Detailed Description

To better explain the technical problems and means to be solved by the present application, the embodiments of the present application are further described below with reference to the accompanying drawings.

To facilitate a better understanding of all the embodiments of the present application, the working direction of the paddy field flatland weeder described in the present application is defined as the Y direction.

Example 1

As shown in fig. 1, the paddy field land leveling weeding machine comprises a frame 1, wherein the frame 1 is made of hard materials (such as steel materials), three hanging points 2 which are arranged in a triangle shape are arranged at the front end of the frame 1, and the hanging points 2 are used for hanging the frame 1 and a traction vehicle. The end of the frame 1 opposite to the hanging point 2 is provided with a flat scraper 3, the cross section of the flat scraper 3 is C-shaped, the inner side of the C-shaped opening forms a concave surface of the flat scraper 3, and the opening direction of the concave surface of the flat scraper 3 is the same as the advancing direction of the operation. The concave surface of the flat scraper is fixed with at least one scraper articulated lug 3-1 and a mode adjusting lug 3-2, the scraper articulated lug 3-1 is used for fixing the flat scraper 3 on the frame 1 in an articulated manner, so that the flat scraper 3 is kept in horizontal fit with the frame. The mode adjustment lug 3-2 is preferably disposed at the center of the grading blade 3 for articulation with the mode switch actuator 4. The mode conversion actuating mechanism 4 is arranged on the rack 1 and comprises a plane connecting rod mechanism 4-1, a connecting part 4-2 and a mode adjusting oil cylinder 4-3, wherein the connecting rod mechanism 4-1 is composed of two hard rod bodies in a hinged mode, one end of the connecting rod mechanism 4-1 is hinged with the mode adjusting lug 3-2, and the other end of the connecting rod mechanism 4-1 is hinged with the rack 1. The joint part of the connecting rod mechanism 4-1 is also provided with a connecting part 4-2, the connecting part 4-2 is used for being hinged with a piston rod of a mode adjusting oil cylinder 4-3, and the tail part of a cylinder body of the mode adjusting oil cylinder 4-3 is hinged with the frame 1.

A plurality of grass pressing plates 5 are arranged on the upper part of the convex surface of the leveling scraper 3 at equal intervals along the length direction, and each grass pressing plate 5 is vertically arranged on the leveling scraper 3, so that the grass pressing plates 5 form arc-shaped bulges on the upper part of the convex surface side of the leveling scraper 3.

Through the mutual matching of the mode conversion actuating mechanism 4 and the frame 1, the land leveling scraper 3 and the grass pressing plate 5 realize the mutual conversion of functions between the land leveling mode and the grass removing mode under the reciprocating motion of the mode adjusting oil cylinder 4-3.

The use process comprises the following steps:

the traction vehicle is connected with the paddy field flat land weeder through the hanging point 2, and the traction vehicle drives the paddy field flat land weeder to move forward. When the land leveling mode is used for operation, the manipulator determines an operation reference plane according to the elevation of the operation land and adjusts the hanging point 2, so that one side of the land leveling scraper 3 adjacent to the ground is in the same reference plane when contacting with the ground. By adjusting the mode adjusting oil cylinder 4-3 in the mode conversion executing mechanism 4, the piston rod of the mode adjusting oil cylinder 4-3 is extended and contracted to drive the connecting rod mechanism 4-1 and the ground scraping plate 3 to move synchronously. The leveling blade 3 is adjusted to the leveling mode, the mode adjusting oil cylinder stops stretching and contracting and keeps locking the leveling blade angle, namely the concave surface direction of the leveling blade is consistent with the advancing direction of the operation. At this time, the leveling scraper 3 rubs the ultrahigh soil to be discharged to the outer side of the leveling scraper 3 or filled into a depression lower than the reference plane, and further leveling of the operation land is realized.

In the closing period or beating period of the paddy field, the mode adjusting oil cylinder 4-3 in the mode conversion executing mechanism 4 is adjusted, so that a piston rod of the mode adjusting oil cylinder 4-3 extends out, the connecting rod mechanism 4-1 and the flat scraper 3 are driven to synchronously move, the state of the flat scraper 3 is adjusted, the flat scraper 3 is locked under the weeding mode operation, namely, the convex surface of the flat scraper 3 is contacted with the ground, and the grass pressing plate 5 is inserted into the ground. The grass pressing plate 5 slides in the soil of the operation land along with the operation traction vehicle, and simultaneously presses grass seeds or weed seedlings into the deep soil to destroy the growth environment or root system of the grass seeds or weed seedlings, thereby achieving the purpose of physical weeding.

The reason why the traditional machine is not favorable for mechanical sowing or rice transplanting because the soil in the hollow pit is pushed and filled by the flat scraper 3 is that the soil filled later is relatively loose, and the original soil is extruded by the flat scraper 3 and has relatively high soil density. In the weeding mode operation of the paddy field land weeding machine, the land leveling scraper 3 needs to press the grass pressing plate 5 into the soil and slide in the soil, so that the soil blocks with higher density are loosened, the density of the soil tends to be average, and the problem is solved well.

In this embodiment, the delta-shaped connection between the hitch point 2 and the towing vehicle is the existing general connection standard, and the detailed connection manner is not described again in this embodiment.

EXAMPLES example 2

In order to reduce the resistance generated by the flat scraper 3 during the operation and facilitate the discharge of the residual soil in a predetermined direction, the present embodiment is implemented by adjusting the vector of the flat scraper 3 with respect to the operation direction. In this embodiment 2, on the basis of embodiment 1, the rack 1 in embodiment 1 is further modified and is designed to be composed of two parts, namely, a first rack 1-1 and a second rack 1-2.

As shown in fig. 2, the first frame 1-1 is a rectangular frame structure, and one side of the first frame adjacent to the towing vehicle is provided with a hitch point 2 arranged in a delta shape, and the other side opposite to the hitch point 2 is provided with an outer ring 6-1. An inner ring 6-2 matched with the outer ring 6-1 is arranged on the second rack 1-2, the outer ring 6-1 and the inner ring 6-2 are nested to connect the first rack and the second rack and can generate relative position rotation, and the outer ring 6-1 and the inner ring 6-2 form a slip ring 6.

As shown in fig. 3, the mode switching actuator 4 is provided on the second frame, passing through the inner slip ring, and the second frame 1-2 is connected to the leveling blade 3 in the same manner as in embodiment 1.

The first frame 1-1 is also provided with a direction vector driving mechanism for driving the inner ring 6-2 to rotate so as to drive the second frame 1-2 to rotate around the center of the sliding ring 6. The direction vector driving mechanism can be driven by a linear actuator represented by an oil cylinder or realized in a mode of a motor and a gear pair. Or other forms of driving devices that can perform the same function, and are not specifically limited herein. The slip ring 6 and the direction vector driving mechanism which are connected with the first frame 1-1 and the second frame 1-2 form a direction vector adjusting device together.

Taking the direction vector driving mechanism as an example, an oil cylinder is adopted, one end of the cylinder body of the oil cylinder is connected with the first rack 1-1 in a hinged mode, and the free end of the piston rod of the oil cylinder is hinged with the inner ring 6-2. The piston of the oil cylinder drives the inner ring 6-2 to rotate, and simultaneously drives the second frame 1-2 fixedly connected with the inner ring 6-2 to generate angle deflection, so that the relative rotation of the flat scraper 3 and the ground is realized.

As shown in fig. 6, in the land leveling mode operation, the operator can push the inner ring 6-2 and drive the second frame 1-2 to rotate relative to the first frame 1-1 by adjusting the extension and contraction of the oil cylinder on the direction vector driving mechanism, so as to change the included angle between the land leveling scraper 3 and the operation direction, reduce the pressure angle between the advancing direction and the resistance direction, and further reduce the operation advancing resistance of the land leveling weeding machine.

Example 3

In order to realize the ground profiling of the leveling blade 3 in this embodiment, in the present embodiment, on the basis of the embodiments 1 and 2, the connection mode between the hitch point 2 of the frame 1 or the first frame 1-1 and the towing vehicle is improved, so that the ground profiling is realized by the directional twisting during the operation.

Because traditional agricultural implement traction vehicle all be equipped with this application the same articulated point 2 that is the setting of article style of calligraphy that arranges, the independent articulated point that wherein lies in upper portion is used for the fixed connection agricultural implement, and it plays the effect of stabilizing agricultural implement and lever fulcrum, and the articulated point that two symmetries in lower part set up is equipped with an hydro-cylinder respectively, and the oil circuit of two hydro-cylinders is parallelly connected form, plays the effect of lever power arm for horizontal lifting agricultural implement.

The embodiment changes the connected mode of the hitching point of original upper portion as the fulcrum into the universal joint connection by the hinge, and the hydro-cylinder of two symmetry hitching points in lower part changes into independent oil circuit, makes hydro-cylinder ability asynchronous motion to the hitching point that drives paddy field flat land weeder of this application around upper portion produces and twists reverse, thereby makes level land scraper blade 3 can make adaptation ground change angle according to the topography change, and then realizes the profile modeling of pasting the ground.
