Technical Field

The invention relates to a plough module for exchangeable mounting on a base frame of a plough device for ploughing according to the preamble of claim 1 and to a plough device equipped with at least one such plough module according to claim 12.

Background

When plowing is carried out by such plowing devices, which are usually towed by a tractor, so-called new excavation is cut from the ground. The new excavation has a lateral zone along which the first cutting element cuts. Furthermore, the new excavation has a bottom area which connects the two lateral areas and is separated from the ground by means of the second cutting element. Accordingly, the ground has a separating surface in the region of the newly excavated bottom surface (the so-called furrow bottom). In this way, approximately rectangular new soil is cut out of the soil, wherein, on the remaining ground, a horizontal cutting surface (furrow bottom) is formed by means of the second cutting element and a vertical cutting surface (furrow wall) is formed by means of the first cutting element. By cutting out the newly excavated soil, a furrow wall is formed on the ground, and the side area of the newly excavated soil is detached from the furrow wall. The ground area thus defines the vertical lowermost surface of the newly turned earth at the moment of separation from the ground.

It should be noted that the terms "horizontal" and "vertical" as well as "above" and "below" relate to the arrangement and design of the ploughing device, which is understood to be intended to rest on the ground and to be movable in the working direction in ploughing operation, and further to the arrangement and design of the ploughing module according to the invention fixed to the ploughing device.

A related ploughing device is known from DE 102017102683 a 1. A first cutting element, which is designed as a cutting disk and which is rotatable, is arranged on the basic frame of the ploughing device, said first cutting element having a circumferential first cutting edge, wherein the first cutting element is designed such that a newly excavated lateral region of the ground can be cut off by the ploughing module being moved in the ploughing direction over the ground. The plowing direction or working direction is defined as the direction in which the plowing device moves over the ground. A flat second cutting member having a second cutting edge is also secured to the base frame and disposed in front of the first cutting member in the direction of plowing. The second cutting element is designed to be able to cut off the newly excavated ground surface region by moving the ploughing module over the ground in the ploughing direction. When ploughing is carried out by means of the ploughing device, the region of the base of the newly excavated soil to be formed is first cut by means of the second cutting element. The following first cutting element, which is designed as an arc-shaped cutting disk, then cuts the newly excavated lateral area and turns it over in the formed furrow. Such plowing devices require only significantly reduced traction forces as compared to conventional plowing using a plow body and brush plate.

A disadvantage of the ploughing device according to DE 102017102683 a1 is that the various cutting elements are mounted individually on the base frame, which makes it difficult to mount or retrofit onto conventional base frames for ploughing. Furthermore, the spatial alignment of the two cutting elements relative to one another is complicated and their adjustment or setting can generally only be carried out to a limited extent.

Disclosure of Invention

The object of the invention is to provide a structural unit which can perform all the functions of the aforementioned ploughing or ploughing method, can be mounted on the base frame of the ploughing device in a replaceable manner and can perform easy ploughing.

This object is achieved by a ploughing module having the features according to claim 1. Suitable refinements are defined in the dependent claims.

This object is achieved by designing the plough module as a completely assembled structural unit and having a first carrier structure on which the first cutting element is arranged and a second carrier structure on which the second cutting element is arranged and which is connected to the first carrier structure, and by providing the first carrier structure with means for detachable fixing to a base frame of the plough device in which the plough module is provided, in which the second cutting element is arranged behind the first cutting element in the plough direction.

According to a first aspect of the invention, a plowing module for a plowing device for plowing is described. The ploughing module has a first carrier structure on which a rotatable cutting element (e.g. an arc-shaped disc) is arranged. A second cutting element, such as another disc or a cutting knife arranged at a defined angle with respect to the first cutting element, is mounted on a second carrier structure, which is in turn firmly connected on one side to the first carrier structure. The rotatable first cutting element has a circumferential first cutting edge and is designed to cut through a newly excavated lateral region of the ground surface, in particular from the furrow wall, by means of a first cutting region of the first cutting edge when the ploughing device is moved with the carrier structure over the ground surface in its ploughing direction (i.e. working direction). The first carrier structure and the second carrier structure are firmly connected to each other and together arranged on a base structure of the plough device. The second cutting element has a second cutting edge, which is arranged on the second carrier structure and is designed such that, when the plough module is moved over the ground surface in the ploughing direction, a bottom region of the newly excavated ground of the ground surface can be cut off by means of a second cutting region of the second cutting edge, in particular along a parting plane between the newly excavated ground and the plough bottom. The second cutting member is arranged in the direction of plowing relative to the first cutting member such that the second cutting zone is located behind the first cutting zone in the direction of plowing.

The position of the respective cutting elements on the plough module relative to each other is preferably adjustable, preferably pivotable. This has significant advantages over known plowing devices. For example, a ploughing module can be used in such a way that a first cutting element for side separation of the new soil is arranged before a second cutting element for bottom separation of the new soil.

Preferably, the plough device has a plurality of plough modules, for example three to eight modules on one plough side, i.e. a total of six to 16 modules for one basic frame. In contrast to known plowing devices, in known plowing devices a first cutting element for cutting the side of the new turn is disposed behind a second cutting element that cuts the bottom of the new turn or furrow from which the new turn is cut. This known arrangement is obviously chosen because the first cutting element, for example in cooperation with the guide plate or in a certain design as a hollow disc, is responsible for turning over the cut-out new spoil. For this purpose, the bottom of the furrow, i.e. the underside of the newly excavated soil, must already be cut. In the known device, the second cutting element is therefore arranged before the first cutting element, taking into account its movable cutting edge. By this arrangement the first cutting element can turn the newly excavated side directly after it has been cut, since the bottom of the furrow has already been cut. In order for the side portion of the first cutting element to be able to be reliably cut, or in a bent configuration also to be ready to be turned and to start turning over new spoil, the driving or mounting or holding of the first cutting element must of course be provided at its rear side. This, however, in turn means that the second cutting elements and the first cutting elements must each have a separate carrier, by means of which they are attached to the frame. This makes it considerably difficult to adjust the two cutting elements relative to each other.

In contrast, in the present invention, the first cutting element that cuts the side of the new turn is disposed before the second cutting element that cuts the bottom surface of the new turn or the bottom surface of the furrow. This is generally not taken into account, since in ploughs in which first the first cutting element for cutting the side of the new turn is arranged in the direction of traction, the turning function cannot be performed despite the shape designed as a hollow disc and mainly provided for turning the new turn. Since the furrow bottom has not yet been cut. The advantage of the module according to the invention is precisely that only two cutting elements need to be provided, without guide plates or brush plates. The advantage according to the invention is now also that, on the basis of the fact that the first cutting element has a drive or bearing or carrier structure on its rear side and in the case of being arranged in front of the second cutting element, which also has a carrier structure, the two carrier structures of the first cutting element and the second cutting element can be connected to each other, so that a module is formed which can be attached to the carrier frame of the plough means by means of a single suspension device. A decisive advantage is that a conventional ploughing device with a plough body can be easily retrofitted by removing the plough body and installing the corresponding modules. Of course, a conventional base frame (also referred to as a plow frame) can be equipped with a plowing module according to the present invention at the factory.

Surprisingly, it has now been shown that in ploughing devices with a front cutting element as a hollow disc, it is possible to cut the side regions without the side regions being cut first of all with subsequent turning, since the furrow bottom has not yet been cut. The turning is only done by the subsequent second cutting element. It has been shown that if a plurality of such modules are arranged one behind the other in the ploughing device, in the second module which follows the first module as seen in the ploughing direction, the first cutting element does not only cut the side of the newly excavated soil which is already present there, but also the ground furrows which are already present there are already cut by means of the first module. The desired function can thus be performed directly by the second module, i.e. the first cutting element in the form of a hollow disc cuts the side of the new turn and at the same time can turn the new turn.

With regard to the construction, it may be beneficial for the holding device or carrier structure of the first cutting element to have a carrier structure for the second cutting element at the rear side, so that two cutting elements can be easily attached and connected into one module. For example, if the plowing set has only one plowing module, then in the first pull of plowing the field, only this first pull is the pull that cuts the side of the new turn that has not been cut out and turns over the turn that has not occurred. On the second pull, however, the cut-off new spoil will be turned over directly by the first cutting element, since the second cutting element has already cut the furrow bottom in this region and thus the underside of the new spoil. This results in considerable advantages compared to conventional ploughing devices. The plough module according to the invention can be exchanged or adapted without further expenditure for conventional plough assemblies with plough bodies. It is also possible to easily replace defective components for modular reasons or to easily replace correspondingly adapted further plough modules on the plough device due to changes in the ground structure.

The plough module according to the invention is particularly advantageous if both the first cutting element and the second cutting element can be adjusted with respect to their position. Thus, an adjustability for the ground to be plowed and an adjustability of the two cutting elements relative to each other are created. The second cutting member is pivotable on a carrier structure that holds the first cutting member to direct the second cutting member slightly downwardly as it cuts the ground to prevent the cutting member at the bottom of the cutting furrow from backing out during plowing and to simultaneously maintain the first cutting member below the ground. The first cutting element can be pivoted and moved in a plurality of directions and thus has a plurality of degrees of freedom in order to achieve a correspondingly optimum plowing result in the cooperation of the two cutting elements with one another.

The provision of a plurality of modules on the plowing device is also advantageous in that a greater width can be plowed in one pull by the device according to the invention. It is also expedient to pivot the cutting elements out of engagement when the edge of the field to be ploughed has been ploughed, otherwise the width of the last traction would be too large, so that there is a risk that e.g. a piece of ground in the adjacent field will be dug out by the ploughing module arranged on the furthest side. To avoid this, this can be prevented by pivoting the cutting element or the respective cutting element out of engagement.

A plow module according to the present disclosure is coupled to a towing machine (e.g., a tractor) via a base frame of the plow assembly such that the tractor pulls the cutting element across the ground surface in the direction of plowing. The base frame may also be part of a carrying iron or plough frame. For a plough module consisting of two cutting elements arranged on a combined carrier structure, i.e. a side for cutting the newly turned soil and a first cutting element for turning and a second cutting element for cutting the plough bottom, the plough frame can be omitted completely. The carrier structure has metal rods and/or fiber composite elements. Furthermore, as will be described in detail below, the attached elements may be adjustably secured to the carrier structure.

The plow frame or carrier frame formed by the first carrier structure and the second carrier structure thus provides a rigid, but adjustable, fixed structure for the cutting elements and additional components (e.g., joints or adjustment elements) on the plow module. In other words, the cutting elements are secured to the respective first or second carrier structure such that there is no relative movement between the cutting elements during plowing. If the second cutting element is pressed into the ground during ploughing as a result of cutting the newly turned earth, the first cutting element is simultaneously pressed into the ground by traction. Preferably, however, the cutting element may also be adjustable during plowing, which may be achieved electrically or hydraulically, for example.

According to an exemplary embodiment, the first cutting element and/or the second cutting element are pivotably fixed to the respective carrier structure, for example by means of joints, such that the angle between the axis of rotation and the direction of extension of the second cutting edge can be adjusted and can be fixed at a desired position. In a further advantageous embodiment of the invention, the second carrier structure itself is pivotably connected to the first carrier structure by means of a joint. As a result, the rake angle of the second cutting member can be adjusted relative to the plowing direction. The rake angle is typically such that the front cutting edge is directed slightly downward into the ground.

In a further exemplary embodiment, the first cutting element and/or the second cutting element are pivotably and/or translatably arranged on the respective carrier structure for adjusting the rake angle and the position relative to each other. Thus, depending on the nature of the ground and on the desired working depth, the rake angle of the second cutting member relative to the direction of plowing can be adjusted.

Devices such as the aforementioned joints are used to adjust the cutting element angle (board angle) and may adjust the cutting element's rake angle (the angle of inclination perpendicular to the furrow wall of the ground) and the cutting element's azimuth angle (toward the plowing direction, i.e., the tractor's direction of travel). The cutting line of the cutting element between the first cutting edge and the furrow wall can be adjusted in height by means of an adjustable support. Thus, the vertical distance and/or the horizontal distance between the first cutting element and the second cutting element may be variably adjustable. In other words, in a further exemplary embodiment, the first cutting element and the second cutting element may be arranged to each other such that the cutting area of the first cutting edge of the first cutting element is vertically spaced apart from the second cutting edge of the second cutting element. By adjustment in the horizontal direction, the cutting width or the plowing width of the tractor can be adjusted.

In one embodiment of the invention, the first cutting region is preferably formed in a first cutting plane and the second cutting region is formed in a second cutting plane, the first cutting plane and the second cutting plane being at an angle of 30 ° to 135 °, in particular at an angle of 45 ° to 110 °, to one another. The desired angle can be adjusted for this purpose in that the two cutting elements are pivotably mounted on the respective associated carrier structure. Of course, a predetermined, fixed alignment of the two cutting planes is also within the scope of the invention.

The first cutting edge extends in a first cutting plane and the second cutting edge extends in a second cutting plane. The first cutting element and the second cutting element are fixed relative to one another on the carrier structure in such a way that the first cutting plane and the second cutting plane are formed non-parallel and in particular have an angle (opening angle) of more or less than 90 ° with respect to one another. In other words, in a further exemplary embodiment, the first cutting element may be arranged such that an angle of about 0 ° to about ± 30 ° is formed between the rotational axis of the first cutting element and the direction of extension of the second cutting edge (or the tangent of the second cut if the second cutting element forms a rotating disc). In particular, when the plough means are intended to be placed on the ground, the normal to the first cutting plane has a (directional) component parallel to the horizontal direction. The axis of rotation of the cutting element is in particular parallel to the normal of the first cutting plane. Furthermore, when the plough means are intended to be placed on the ground, the normal of the second cutting plane has a further (directional) component, which is parallel to the vertical direction. For example, the angle between the normals may be selected between 45 ° and 130 ° to achieve a desired furrow pattern in the subsurface.

If the first cutting surface and the second cutting surface are, in particular, approximately 90 ° to each other, the second cutting element presses the undercut fresh spoil in the direction towards the first cutting element. As a result, advantageously new turning between the first cutting element and the second cutting element can be handled during the movement in the ploughing direction. The cooperation of the two rotating mechanical elements, i.e., the first cutting element and the second cutting element, has a preferred plowing result or "break" (clod breaking). Furthermore, the strong lateral pulling forces of the first cutting element, which have a negative effect on the traction wire of the tractor, are largely compensated by the reaction of the second cutting element. The tractor remains on the track without much counter-rotation.

The first cutting element is rotatably or rotatably fixed to the first carrier structure. Accordingly, the first cutting element has a first rotational axis about which the first cutting element rotates. The first cutting element is preferably designed as an arc-shaped cutting plate and has a circular line of a circle. The first cutting edge in the circumferential direction is formed along a circular line. By means of the first cutting edge, the lateral region of the newly excavated soil is separated from the furrow wall and at the same time the newly excavated soil is diverted laterally. The first cutting edge in the circumferential direction has a first cutting region. The first cutting region is a circumferential section of the first cutting edge, which circumferential section in the ploughing direction preferably first comes into contact with the ground and cuts the ground. The first cutting element may have a diameter of about 500mm to about 800 mm. Furthermore, the first cutting element may have teeth, be centrally mounted and may be position-adjusted relative to the first carrier structure and the second cutting element, preferably by means of a slide.

It is particularly advantageous if the first cutting element, which is rotatable about the axis of rotation, is arcuate or has a conical or frustoconical shape. Thereby ensuring that the severed new turn of earth is rotated and deposited in the adjacent furrow created by the passage of the plowing module. The axis of rotation of the first cutting element is adjusted at an angle to the direction of plowing, such that the leading edge of the cutting element is lowered with respect to the direction of plowing and the cutting element extends essentially obliquely to the direction of plowing and thus extends towards the new excavation from the cutting element to the cut.

The first cutting element automatically rotates as the plow assembly moves along the ground surface. Whereby the friction forces cause the first cutting member to move. The first cutting element is preferably dimensioned such that only the lower half of the first cutting element, which is located below the first rotation axis, penetrates the ground during ploughing, so that friction with the ground can cause rotation.

The rotation of the first cutting element, which is formed in an arc or plate shape, also causes the cut new turned earth to be lifted and at the same time turned to the side. The severed fresh spoil is in particular in frictional contact with the first cutting surface of the first cutting element. The first cutting surface is a surface of a first cutting element formed in the first cutting edge. Furthermore, the first cutting surface is the surface directed to the detached newly excavated soil. The first cutting surface may be designed uniformly without recesses or protrusions. Further, the first cutting surface (i.e., the outer side surface of the first cutting element) may be formed in a conical shape or a frustoconical shape.

In a preferred embodiment, the second cutting element is designed as a disc and is rotatably mounted, wherein the second cutting edge is defined by a circumferential edge of the second cutting element. Alternatively, the second cutting element may be realized by an adjustable cutting blade having a cutting edge extending transversely to the ploughing direction. The cutting element, which is preferably serrated on its cutting edge, is preferably oriented slightly rearwards, i.e. with a defined angle, with its tip relative to the direction of the plough. The included angle between the plough and the ploughing direction is more than 90 degrees. By means of the second cutting edge, the newly excavated ground surface region is separated from the trench bottom of the ground, undercut and, if necessary, lifted at the same time. In the case of a rotatable disc, the second circumferential cutting edge has a second cutting area. The second cutting zone is the circumferential section of the second cutting edge that subsequently contacts and cuts the ground in the plowing direction.

A first cutting element, such as an arcuate disk, cuts the new turn at a first vertical level, for example starting from a working depth of about 15 to 35 centimeters from the ground surface, and directs the new turn into the pre-formed furrow.

At a second, horizontal level, about 15 to 35 cm working depth from the ground surface, the freshly excavated earth is cut horizontally by a second cutting element, i.e. from the bottom of the furrow.

The distance between the two cutting planes (upper: the first vertical cutting element rotating; lower: the second horizontal cutting element) can be adapted by adjusting the rotating cutting element.

An effective plow body is comprised of the primary components of a first arcuate cutting member and a second planar cutting member (e.g., a cutter or rotatable disc) generally corresponding to an inclined plane of wrap drawn through the ground. The cut-off fresh cut soil moves upward along the curved first cutting members of the inner and side surfaces thereof. This process involves compressing the upper half of the newly excavated earth and stretching the lower half. As a result, compressive, tensile and torsional stresses are generated in the newly excavated soil, resulting in soil splitting.

By the arrangement according to the invention of the second cutting element in the direction of ploughing behind the first cutting element, the friction forces which would otherwise result in the required high pulling forces of the ploughing device can be reduced. Since the new spoil has been separated from the furrow bottom by the second cutting member as it is cut from its side by the first cutting member, the new spoil has been lifted and turned by the first cutting member. The second cutting region is located behind the first cutting region in the direction of plowing, for example between 1cm and 50cm, in particular between 15cm and 25 cm. The second substantially horizontal cutting disc or blade is in contact with the ground as the second cutting disc and may be said to extend behind or behind the first substantially vertically arranged cutting disc or element. This arrangement of the second cutting element "undercuts" the furrow wall or new excavation to be plowed horizontally, thus significantly facilitating raking/furrow clearing. The vertically arranged curved first cutting element vertically cuts the freshly excavated soil, which has been horizontally pre-cut by the downstream second cutting element, during the subsequent pulling, while the freshly excavated soil is turned over and laterally placed, preferably into the furrow, by the rotary movement of the hollow disc.

Therefore, the plowing device can realize a stable plowing effect. The coefficient of friction is greatly reduced compared to conventional rigid plow bodies because the cutting element rotates therewith. In this sense, a smoothly running, fuel efficient plow is provided, while the plow produces a constant furrow pattern that is nearly ready for use on the seedbed.

According to a further exemplary embodiment, the second cutting element is an actively rotatable cutting element and the second cutting edge is a cutting edge surrounding the second cutting element. The second cutting element may be driven or rotated by an electric or hydraulic drive.

According to a further exemplary embodiment, the first cutting edge or the second cutting edge of the first cutting element or of the second cutting element is of arcuate tooth form and is designed, for example, as a concave disk. The curved design means that a depression or a protrusion (tooth) is formed in the first cutting edge or the second cutting edge. Thus, an improved cutting effect of the first cutting element or the second cutting element may be achieved when separating new spoil. By means of the spherical cap design, in particular of the first cutting element, the newly turned soil sliding along the first cutting element can be turned over, so that a connecting brush or guide plate can be dispensed with. Advantageously, the first cutting edge of the first cutting element and/or the second cutting edge of the second disc-shaped cutting element has a recess in the circumference. This results in a design in the form of a circular saw blade which penetrates the ground particularly easily and can be set into rotation by engagement with the ground.

By means of the described plough device, traction/fuel can be saved due to the easy traction of the plough device. In addition, the plow assembly can be used universally and can work under almost all terrain conditions. Furthermore, the new turning is constantly damaged by the rotating movement of the cutting board. This achieves the desired soil block crushing (soil block breaking). Due to the soil block crushing effect, the post-treatment steps can be reduced. This saves the work steps up to the treatment of the seedbed. Furthermore, the soil is advantageously mixed. Furthermore, the conventional standard components or standard additional tools, such as fertilizer skimmers and circular coulters, are no longer required. The rotating first cutting element and/or second cutting element produces less wear and tear and therefore less replacement part costs. With this good ground plowing, humus damaging metal wear by the cutting elements is largely avoided or reduced as compared to plowing devices using conventional plow plates.

According to a further exemplary embodiment, the ploughing device has at least one further ploughing module, which further has a rotatable first cutting element having a circumferential further first cutting edge and is designed such that, when the carrier structure is moved in the ploughing direction over the ground surface, a further lateral region of a further new turn of the ground surface can be cut off by the further ploughing module and the further first cutting element, so that the further new turn can be lifted by the further first cutting element.

As can be seen from the above embodiment, the plurality of plowing modules are arranged adjacent to each other in the plowing direction, that is, spaced and aligned in a direction orthogonal to (in a horizontal plane) the plowing direction. Thus, a large amount of new soil, arranged side by side in the ploughing direction, can be cut off from the ground, lifted and, if necessary, turned over.

When a large number or a plurality of corresponding plough modules are arranged and a corresponding number of cutting elements are arranged one behind the other in the direction of ploughing, a wider area can be ploughed by pulling at once, compared to the case of using only one plough module, due to the use of separate plough modules laterally to one another transversely to the direction of ploughing. Likewise, it is advantageous for the function of the plough device if the cutting elements are disengaged and can therefore be pivoted out of their adjustment position. This makes it possible, for example, to convert the following cutting element into a leading cutting element. In the case of a combination of a plurality of ploughing modules of a ploughing device, this can be of interest or advantageous for different parameters, for example the ground properties in the sense of optimum adaptation.

For example, with the plough device according to the invention, even without a guide plate and a plough plate, a new turn of the ground can be turned gently and flatly, for example 15cm, by the upper rotatable curved first cutting element.

In an exemplary embodiment, the first cutting element and the second cutting element are exchangeably arranged (e.g. by a threaded connection) on the respective carrier structures. The first carrier structure is designed such that it can be detachably mounted on the base frame of the plough device, this preferably being done by means of a screw connection. Shear bolts may also be provided to protect the stone. The mounting elements provided for this purpose, such as holes or pins, are preferably designed and arranged such that they are compatible with commercially available basic frames for plough assemblies. The plough module can thus be easily converted into a base frame of the plough device, for example on the plough body.

Due to the rotation of the first cutting member, the cut fresh spoil is easily lifted, turned and placed onto the furrow. When the plowing device moves along the plowing direction, new turned soil is placed along the plowing direction.

Since the new soil is lifted by the rotating first cutting element, the new soil can be deposited behind the cutting element in the ploughing direction in an energy-saving manner.

In a particularly preferred embodiment of the plough module according to the invention, the second cutting element is designed as a stationary cutting knife. The cutting knife is designed as a flat, rectangular, straight or curved blade which is fixed to the second carrier structure in the end region. Preferably by means of a thread, which also makes it possible to easily replace the second cutting element when worn. The cutting edge of the blade in its working position points in the direction of plowing and is generally oriented transversely thereto.

In an advantageous embodiment of the design, the cutting knives of the second cutting element are L-shaped, the first bars of the cutting knives being oriented horizontally in the working position of the ploughing module and the second bars being oriented substantially vertically. The first bars thus separate the bottom area of the new turn to be formed. While in the working position of the plough module the vertical second bar is located in front of the first cutting element and facilitates access to the ground surface, since the second bar extends substantially in the same plane as the leading edge of the first cutting element. For reasons of mechanical robustness, it is advantageous to design the cutting knife in one piece. The cutting knives are generally in the shape of flat blades with sharp edges on the front side of the blade. The rake angle of the blades relative to the direction of plowing can be adjusted to ensure that the desired depth of plowing module into the ground is achieved and maintained.

The invention also comprises a plowing device, on the base frame of which at least one plowing module according to the invention is arranged, preferably 6 to 16 such plowing modules are arranged, according to claim 12. In this case, the plough module is firmly connected to the base structure, preferably by means of a screw connection, which connection is made by means of the first carrier structure. It goes without saying that compatible fixing elements, for example holes or bolts, have to be formed on the base frame and the first carrier structure. Alternatively, an adapter element can also be provided in order to be able to adapt and fix the plough module to different base frames of the plough. The plough module can thus be easily mounted on the base frame or, for example, be removed for maintenance purposes.

Detailed Description

Fig. 1 shows a ploughing module for ploughing a ground surface 120, in which first cutting elements 102 in the form of spherical cap-shaped hollow discs are arranged before second cutting elements 105 in the form of planar discs one behind the other in the ploughing direction. The first cutting member 102 is provided for cutting the newly excavated side surface, while the second cutting member 105 arranged behind the first cutting member 102 is designed as a planar disc which cuts the furrow bottom surface. The two cutting elements 102, 105 are connected together as a ploughing module by means of the carrier structures 4, 5. The carrier structures 4, 5 may be fixed to a base frame (not shown) and the second cutting member 105 is connected in an articulated manner to the first cutting member 102 via the carrier structure 4 of the first cutting member.

As shown in fig. 1, a rotatable first cutting element 102 with a circumferentially curved first cutting edge 103 is arranged on the first carrier structure 4 and is designed such that, when the carrier structure 4 is moved over the ground 120 in the ploughing direction 110, as shown in fig. 2, a lateral region 202 of a newly excavated earth 201 of the ground 120 can be cut by the first cutting region of the first cutting edge 103 (see fig. 2). The direction of plowing 110 is defined as the direction in which the plowing device 3 moves on the ground 120. A second cutting element 105 having a second cutting edge 106 is arranged on the second carrier structure 5, which second carrier structure 5 is detachably connected to the first carrier structure 4 and can be pivoted relative thereto. The second cutting element 105 is designed such that, when the carrier structure 5 is moved in the direction of plowing 110 over the ground surface 120, the bottom region 203 of the new excavation 201 of the ground surface 120 can be cut by the second cutting region of the second cutting edge 106, wherein the second cutting element 105 is arranged in the direction of plowing 110 relative to the first cutting element 102 such that the second cutting region is arranged behind the first cutting region in the direction of plowing. Thereby, the second cutting region is spaced apart from the first cutting region by a distance x.

Since the base frame 2 of the plough module 1 with the first carrier structure 4 and the second carrier structure 5 is pressed in the direction of the parting plane 121 of the ground surface 120 during the ploughing process, the first cutting element 102 is correspondingly pressed in the direction of the parting plane 121 of the ground surface 120, so that the first cutting element 102 remains at the desired soil depth during the ploughing.

Fig. 2 shows a schematic view of important functional elements of a plowing device according to an exemplary embodiment of the present invention during plowing. Fig. 2 shows the exact spatial arrangement of the first cutting element 102 and the second cutting element 105 and the formation and turning of the new excavation 201. For the sake of clarity, the other components of the associated ploughing device 3 are not shown.

As shown in fig. 2, a so-called new turn 201 is cut out of the ground 120 during plowing. The new excavation 201 has a lateral zone 202 along which the first cutting element 102 cuts. Furthermore, the new excavation 201 has a bottom surface region 203 which connects the two side regions 202 and is separated from the ground 120 by a second cutting element 105, here shown as a double L-shaped fixed cutting blade 6. Accordingly, the ground 120 has a separating surface 121, a so-called furrow bottom 121, on the bottom surface region 203 of the new soil 201. After cutting out the new turn 201, the furrow wall 122 can be seen in the ground 120 from which the lateral region 202 of the new turn 201 has detached. The ground area 203 thus defines the lowest level of the new excavation 201 in the vertical direction at the moment of separation from the ground 120. The side regions 202 of the new excavation 201 define the sidewall regions of the new excavation 201 at the moment of separation from the ground 120.

As shown in fig. 1, the carrier structures 4 and 5 for the two cutting elements 102 and 105 are designed to connect at least the first cutting element 102 and the second cutting element 105 together firmly to the base frame 2 of the plough means 3. The first carrier structure 4 can be fixed to a towing machine (for example a tractor) by means of the base frame 2 of the plough device 3 in order to drive the cutting elements 102, 105 accordingly in the plough direction 110. The plough module 1 has, for example, a first carrier structure 4 and a second carrier structure 5, which can be designed to be fixed or pivotable by means of a joint.

The first carrier structure 4 and the second carrier structure 5 thus form a rigid, fixed structure for the cutting elements 102, 105. The cutting members 102, 105 are secured to the carrier structures 4, 5 so that there is no relative movement between the positions of the cutting members 102, 105 during plowing. According to the invention, if the second cutting member 105 is pressed against the ground 120 due to the cutting of the new excavation 201, the first cutting member 102 is also pressed under the ground 120 at the same time, since the two carrier structures 4, 5 are firmly connected to each other.

The first cutting element 102 and the second cutting element 105 are rotatably fixed to the respective carrier structure 4 or 5. Accordingly, the first cutting member 102 has an axis of rotation 108 about which the cutting member 102 rotates. The second cutting element 105 forms a second rotation axis 109 about which the second cutting element 105 rotates. The first cutting element 102 and the second cutting element 105 are here designed, for example, as spherical cutting disks or planar disks and have a circular circumference. Respective circumferential first and second cutting edges 103, 106 are formed along the circumference. By means of the first cutting edge 103, the side region 202 of the new turn 201 is separated from the furrow wall 122 of the ground 120. The first circumferential cutting edge 103 has a cutting region 104. The cutting region 104 is the circumferential section of the first cutting edge 103 which, in the direction of plowing 110, first comes into contact with the ground 120 and cuts it. By means of the second cutting edge 106, the floor area 203 of the new excavation 201 is separated from the ground 120. The second cutting region of the second cutting edge 106 is a circumferential section of the second cutting element 105, which in the direction of plowing 110 then makes contact with the ground surface 120 or which follows the first cutting element and cuts the ground surface. The double arrow 12 in fig. 2 indicates that the second cutting member 105 is pivotably mounted on a second carrier structure 5, not shown here. Said pivoting allows the rake angle of the cutting blade 6 with respect to the direction of plowing to be adjusted, thus allowing the depth of penetration of the plowing module 1 into the ground 120 to be adjusted.

The rotatable disc coulter 13 may be arranged in front of or in connection with the ploughing module 1, cutting or slicing the ground 120 beforehand before the vertical second new excavation 9 of the cutting blade 6 and the first cutting element 102. As a result, the pulling force required for plowing is reduced, as is the wear of the cutting blade 6 and the subsequent first cutting element 102. The cutters cut horizontally and vertically as double or triple edged cutters.

As the plowing device 3 moves along the ground surface 120, the first cutting member 102 rotates. In this case, for example, friction forces generate the cutting element 102 movement. Wherein the cutting members 102 are sized such that only the lower half of the first cutting member 102 below the rotational axis 108 enters the ground 120 during plowing, such that frictional forces with the ground 120 cause the rotation.

The rotation of the first cutting member 102 also produces a lifting of the cut new spoil 201. This is illustrated in fig. 2 by an arrow which indicates the transport direction 123 of the new soil 201 along the ploughing device 3.

The severed new excavation 201 is in frictional contact with the cutting surface 113 of the cutting element 102. The cutting surface 113 is the surface of the cutting element 102 formed within or surrounded by the first cutting edge 103. Further, the cutting surface 113 is a surface directed to the cut-off fresh soil 201. As shown in fig. 1, the cutting surface 113 may be uniformly formed without depressions or protrusions.

As the new turn 201 is lifted by rotating the cutting member 102, the new turn 201 can be sent to the adjacent furrow in an energy efficient manner. The furrows are dug out as they pass before the plowing module, as shown in fig. 2.

According to fig. 1, the first cutting element 102 and the second cutting element 105 are fixed relative to one another to the carrier structure 4, 5, i.e. the cutting region 104 of the first cutting element 102 is spaced apart in the vertical direction from the second cutting element 105 or above the second cutting element 105 when the ploughing device 3 is located on or into the ground 120 in the working position.

The rotating cutting element 102 and the second cutting element 105 work together in an advantageous manner. On the one hand, the required plough depth is kept constant by means of the second cutting element 105, since the cut-off new soil 201 presses with a defined pressure/traction force on the second cutting element 105 and thereby counteracts the lifting of the rotating cutting element 102. On the other hand, the energy-saving effect of the rotating cutting element 102 is utilized when cutting the new excavation 201, in particular when cutting the lateral surface or lateral region 202 of the new excavation 201. Thus, an energy-efficient plowing set 3 is provided without adversely affecting the quality of the furrow pattern. In addition, the rotating second cutting element 105 causes the cut-off fresh soil 201 to be pressed in the direction of the first cutting element 102, thereby performing the fragmentation of the cut-off fresh soil 201. Furthermore, due to the lateral forces introduced into the first carrier structure 4 by the upstream second cutting element 105, the lateral forces introduced onto the first cutting element 102 during cutting are counteracted, so that the ploughing device 3 can be guided more easily and better by means of a towing machine.

The first cutting element 102 and the second cutting element 105 are arranged relative to each other on the first carrier structure 4 and the second carrier structure 5 such that a second cutting region 107 of the second cutting edge 106 of the second cutting element 105, which comprises a front half of the second cutting element 105, is located behind the first cutting region 104 of the first cutting edge 103 of the first cutting element 102 by a distance x in the plough direction 110. Thus, during plowing, the rotating first cutting element 105 first strikes the new turn 201 laterally and cuts the new turn from the remaining ground 120 with the second cutting edge 106 of the second cutting element 105 in an energy-efficient manner. The first cutting element 105 then cuts the lateral region 202 of the new excavation 201 with the first cutting edge 103. The second cutting member 105 undercuts the furrow wall cut with the first cutting member 102 (. in this way, the subsequent cutting member 102 of the subsequent module can vertically cut and turn the new turn laterally, then the new turn 201 is rotated by the arcuate shape of the first cutting member 102 and its oblique orientation with respect to the plowing direction and placed in the furrow beside it the first and second cutting members 102, 105 thus cut the new turn 201 in an energy efficient manner and they are simultaneously maintained at the desired cutting depth by means of the pressure acting on the second cutting member 105.

The second cutting element 105 undercuts the new excavation 201 in one area (approximately half a disk). Another fixing area of the second cutting member 105 on which a fixing rod/fixing shaft (rotation shaft 109) for fixing to the first carrier structure 4 is arranged is formed at the side of the second cutting member 105 facing away from the first cutting member 102. Thus, the fixed bar/shaft extends in the already treated furrow during plowing, which reduces the pulling force of the plowing device 3.

The carrier structures 4, 5 are designed such that the first cutting element 102 and/or the second cutting element 105 can be adjusted relative to one another along the direction of plowing 110 and/or vertically, i.e. orthogonally to the direction of plowing 110. For example, the first cutting element 102 may be movably fixed to the carrier structure 4 by means of a bolt connection 115, which bolt connection 115 may engage in an elongated hole 116 in the first carrier structure 4. By adjusting the distance of the cutting elements 102, the second cutting elements 105 and the carrier structures 4, 5 in the direction of plowing 110, the plowing device 3 can be adapted to the specific conditions of different types of soil and used in an efficiency optimized manner. Furthermore, if the element is deformed after the ploughing device 2 is used, the element can be readjusted.

Furthermore, the carrier structures 4, 5 may be designed such that the first cutting elements 102 along the direction component of the first rotation axis 108 and the second cutting elements 105 along the direction component of the second rotation axis 109 may be adjusted relative to each other. In particular, the angle between the first rotation axis 108 and the second rotation axis 109 may be adjusted. The first cutting edge 103 extends in a first cutting plane and the second cutting edge 106 extends in a second cutting plane. The first cutting element 102 and the second cutting element 105 are here fixed relative to each other to the respective carrier structure 4 or 5 such that the first cutting plane and the second cutting plane are not parallel and have an angle relative to each other. For example, the angle between the first rotation axis 108 and the second rotation axis 109 is smaller than 90 °, in particular between 45 ° and 80 °.

Accordingly, by means of the flexible connection of the cutting element 102 and/or the second cutting element 105 to the carrier structures 4 and 5, the distance between the cutting area 104 of the first cutting edge 103 of the cutting element 102 and the second cutting edge 106 of the second cutting element 105 can be adjusted.

Fig. 3 shows a ploughing module 1 according to an exemplary embodiment of the present invention, in which the second cutting element 105 is alternatively formed as a rotating disc 16 or as a fixed cutting knife 6.

The first cutting element 102 and/or the second cutting element 105 may be pivotably fixed (e.g. by means of a joint) to the respective carrier structure 4 or 5, so that the angle between the first rotation axis 108 and the second rotation axis 109 can be adjusted and can be fixed in a desired position. This possibility is illustrated here by way of example by a hydraulic cylinder or spindle 15 which connects the second cutting element 105, which is mounted pivotably in the second carrier structure 5, to the first carrier structure 4. The position of the first cutting element 102, here shown exemplarily as a concave disc with a curved edge, may also be adjusted relative to the first carrier structure 4, for example hydraulically. By such adjustment, the width of the furrow 14 formed or the fit of the two cutting members 102 and 105, among other things, may be affected.

The first cutting element 102 in fig. 3 has a spherical cap shape and has a corresponding fixation area on its first rotational axis 108, which fixation area is formed in a fixation plane. The circumferential first cutting edge 103 extends in a first cutting plane, wherein the fixed plane is spaced apart from the cutting plane along the rotational axis 108. The cutting surface 113 of the cutting element 102 is formed between the circumferential first cutting edge 103 and the fixing zone.

Fig. 4 shows a plough device 3 according to the invention as a plough-bed device, on the base frame 2 of which three plough modules 1 according to the invention are shown by way of example. Each of the three plough modules shown has a first cutting member 102 and, following it, a second cutting member 105, which are each connected to the first carrier structure 4 and the second carrier structure 5 to form an integrated plough module, wherein the second carrier structure 5 is pivotably hinged on the first carrier structure so that the second cutting member 105 can have at least a small front angle down into the soil in order to exert the necessary pressure on the plough means to maintain the desired plough depth and to ensure that the first cutting member 102 formed as a hollow disc cuts the side of the newly ploughed soil at the desired depth. When plowing in the direction of plowing indicated by arrow 110, a first cutting member 102 having a circumferential cutting edge 103 for cutting the side of the newly excavated earth is located in front of a second cutting member 105 also having a circumferential cutting edge 106 for cutting the furrow floor. The first coupling part 20 is used for connecting the plough means 3 to, for example, a towing machine, the first coupling part 20 being hinged to a second coupling part 21, which is formed generally in the shape of a bar. The second coupling part 21 substantially represents the base frame 2. The ploughing module 1 is attached to the base frame 2 by means of a joint 19.

When pulled on the ground 120, a part of the plough module enters under the ground 120 to a structurally predetermined depth and in this case the new soil 201 produced emerges. The plough modules 1 are arranged here substantially staggered one after the other, so that a number of new ploughs corresponding to their number is produced, as shown in fig. 2. These new turns 201, after turning over when leaving the first cutting member 102, are located in the furrow 14 formed by the previous cutting member 102, as shown in fig. 2.

Finally, fig. 5 shows the plough device 3 in a plan view, wherein six plough bodies 24 are arranged next to one another in pairs. The plow body 24 is indicated by a double arrow and can be exchanged for a plowing module 1 according to the invention. This is particularly simple in terms of installation work, since the entire plough module 1 can be exchanged for the plough body 24 originally mounted on the plough device without a significant increase in installation work. The ploughing module 1 according to the present invention has a first front cutting element 102 for cutting the side of the new turn and a rear cutting element 105 for cutting the furrow bottom surface. The second cutting element 105 is fixed to the carrier structure 5, while the first cutting element 102 is attached to the first carrier structure 4. The carrier structure 4 and the carrier structure 5 are connected to each other and to each other such that the second carrier structure 5 can be pivoted in order to be able to adjust the rake angle of the second cutting member 105 relative to the furrow ground. The first cutting member 102 can be adjusted in several degrees of freedom, so that on the one hand the plough width can be adjusted and on the other hand the cooperation between the first cutting member 102 and the second cutting member 105 can be adjusted depending on soil parameters and other parameters. For example, the first cutting member 102 is adjustably attached to the first carrier structure 4 by means of a slider 23, such that its height can be adjusted relative to the plane cut by the second cutting member 105.
