Technical Field
The present disclosure relates to harvesters, and more particularly to a lighting mechanism for aligning harvesters in a field.
Background
Agricultural machines, such as combine harvesters, can operate and harvest crops at different times of a given day. This may include dusk or later when it is more difficult for the operator to see a distance in front of the agricultural machine. This is especially more difficult for an operator looking to either side of the agricultural machine, especially when the machine includes an implement such as a harvesting header or draper head having a significant lateral width. At dusk, it can be challenging for the operator to align the agricultural machine and header with the crop rows in the field.
Accordingly, there is a need for a lighting mechanism that is located on the header at a location that can be seen by an operator of the cab of the agricultural machine and that facilitates alignment of the header in the field.

Detailed Description
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments described herein and illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications in the illustrated devices and methods, and such further applications of the principles of the disclosure as illustrated herein being contemplated as would normally occur to one skilled in the art to which the disclosure relates.
In fig. 1, an embodiment of an agricultural combine 10 having a chassis 12 is shown with wheels 14 in contact with the ground. Wheels 14 are connected to the chassis 12 and are used to propel the combine 10 forward in a forward operating or travel direction. The forward operating direction is to the left in fig. 1. The operation of the combine harvester 10 is controlled from the operator's cab 16. The operator's cab 16 may include a number of controls (not shown) for controlling the operation of the combine harvester 10. A cutter head 18 is provided at the forward end of the combine harvester 10 and is used to harvest a crop (such as corn) and direct it to an inclined conveyor 20. The harvested crop is directed to the inclined conveyor 20 by a guide drum 22. As shown in fig. 1, the guide cylinder 22 guides the harvested crop through an inlet transition 24 to an axial harvested crop processing apparatus 26.
The harvested crop processing apparatus 26 may include a rotor housing 34 and a rotor 36 disposed therein. The rotor 36 comprises a hollow cylinder 38, to which hollow cylinder 38 crop handling elements for a charging section 40, a threshing section 42 and a separating section 44 are fastened. The loading section 40 is arranged at the front end of the axial harvested crop processing apparatus 26. The threshing section 42 and the separating section 44 are positioned downstream of the charging section 40 in the longitudinal direction and behind the charging section 40. The barrel 38 may be in the form of a truncated cone located in the charging section 40. The threshing section 42 may comprise a front section in the form of a truncated cone and a cylindrical rear section. The cylindrical separating section 44 of the drum 38 is located at the rear of the axial harvested crop treatment unit 26 or at an end thereof. Instead of an axial harvested crop processing unit 26, it is also possible to use a tangential threshing cylinder with a subsequent axial threshing section or straw chopper.
Grains and chaff falling through a threshing basket associated with the threshing section 42 and through a separating screen associated with the separating section 44 may be directed to the grain cleaning system 28 having a blower 46 and screens 48, 50 with louvered baffles. The screens 48, 50 may be vibrated in the front-to-rear direction. The cleaning system 28 removes chaff and directs the clean grain on a screw conveyor 52 to a lift (not shown) for the clean grain. The elevator for the clean grain deposits the clean grain in the grain bin 30 as shown in fig. 1. The clean grain in grain bin 30 may be unloaded to a grain truck, trailer, or truck (not shown) by means of an unloading auger 32. The harvested crop remaining at the lower end of the lower screen 50 is in turn conveyed to the harvested crop processing apparatus 26 by the screw conveyor 54 and an overhead conveyor (not shown). Harvested crop residue, including primarily chaff and small stalk particles, passing at the upper end of the upper screen 48 may be transported to the rear by means of a vibrating plate conveyor 56 and to a lower inlet 58 of a chopper rotor assembly 60.
The blower 46 described above generates an air flow that carries large quantities of chaff and small particles to the rear of the combine and to the chopper rotor assembly 60. The blower 46 can provide three or more air paths within the combine. A first air path or flow path may pass through a front portion of the combine harvester 10. The second air path or flow path may be located above the lower screen 50 and below the upper screen 48 or chaffer screen. A third air path or flow path may be located below the lower screen 50. All three air or flow paths fill the combine body and are capable of generating a flow of compressed air to pick up and carry stalks, grains and other residue or particles to the rear of the combine 10.
The threshed stalks exiting the separating section 44 are discharged from the harvested crop processing apparatus 26 through an outlet 62 and directed to a discharge chute 64. A discharge drum 64 or discharge beater interacts with a plate 66 disposed therebelow to discharge the stalks rearwardly and the grain and material other than the grain (MOG) is directed through the cleaning system 28. The wall 68 is located rearward of the discharge tube 64. The wall 68 guides the stem into the upper inlet 70 of the shredder rotor assembly 60.
The shredder rotor assembly 60 may include a housing 72 (i.e., a shredder housing) in which rotors 74 are disposed, the rotors 74 being rotatable in a counterclockwise direction about axes extending horizontally and transverse to the operating direction. The rotor 74 may include a plurality of shredder blades 76, the plurality of shredder blades 76 depending and distributed in pairs around the circumference of the rotor 74, the shredder blades 76 interacting with opposing blades 78 secured to the housing 72.

In conventional harvesting applications, an operator may operate the agricultural machine at dusk or at a later time when natural light is unavailable. Thus, the agricultural machine may include a conventional field light that may project light around or in front of the agricultural machine. However, with the floor lights, it is difficult for the operator to see the entire width of the harvesting header. As a result, operators are often challenged by: the laterally outermost edges of the header (i.e., the
To address these challenges, the present disclosure seeks to add a light emitting device to the end of the crop divider stalk at the end of the header. The light emitting device may be oriented in such a way that it directs light back and up towards an operator located in the cab of the agricultural machine. An example of this is shown in fig. 3. Here, a view is provided from the locus of the operator of the agricultural machine traveling in the forward direction of travel 300. The cab may include a first cab window 302 and a second cab window 304. For example, the operator can see one side of the harvesting header when looking out of the first cab window 302.
The harvesting header may be similar to that shown in fig. 2. The header may include a frame 306 to which the pick-up reel is rotatably connected. The spool may be similar to the
As shown in fig. 3, a portion of the crop divider assembly 308 can be seen from the cab. The crop divider assembly 308 may include a divider shroud (divider shroud) 310, the divider shroud 310 being attached to the front tip of the crop divider assembly 308. The crop divider shroud 310 defines a forward most tip or edge of the crop divider assembly 308. The crop divider bar 312 is also visible from the cab through the first cab window 302, although a portion of the crop divider bar 312 is blocked by the reel. As shown, in any event, the crop divider bar 312 may be connected to the forwardmost edge or tip of the crop divider assembly 308.
As also shown in fig. 3, the light mechanism 314 is shown illuminated. The light emitting mechanism 314 may be connected to the end of the crop divider bar 312. The lighting mechanism 314 is located above the ground and is oriented at least partially rearward so that the operator can see the lighting mechanism 314 from the cab. Further, the light emitted by the light emitting mechanism 314 is not projected forward, which in some cases may fool the operator in aligning the header with the crop row. Additionally, the light emitting mechanism 314 is not the first structure that engages the crop, but rather the crop divider bar 312 is the first structure that engages the crop as the header traverses through the field in the forward direction of travel 300.
Although only one end of the harvesting header is shown, it will be understood that similar crop divider bars and lighting mechanisms may be located at the opposite end of the harvesting header in related embodiments. In such a related embodiment, the operator would be able to visually detect the lateral end of the header by means of the light emitting device 314.
Another feature of the lighting mechanism 314 is its placement relative to the crop divider assembly 308 and the ground. In one example, the crop divider bar 308 may extend upward up to a distance of one meter from the ground. The length of the crop divider rod may vary, and in some cases the length may be less than or greater than one meter. In any event, the divider bar 308 extends far enough above the ground and crop divider assembly 308 that the light emitting mechanism 314 is visible when harvesting wheat, beans, or other smaller grain. Accordingly, the present disclosure provides a lighting mechanism 314 that is visible to an operator from the cab of the agricultural machine regardless of the size or type of crop being harvested.
The light emitting mechanism 314 is also positioned outwardly in front of the cab and crop divider assembly 308. Thus, in addition to its positioning at least one foot or more above the ground, the light emitting mechanism 314 is located in front of the header to allow the operator to better align the end of the frame 308 with the crop row.
The light mechanism 314 may include a light emitting diode. In other examples, the light emitting mechanism 314 may take the form of any other conventional type of light emitting device. The light mechanism 314 may include a light bulb or a light emitting diode that receives electrical power from a power source (not shown). In one embodiment, the light emitting mechanism 314 may emit light of a particular color. For example, the light emitting mechanism 314 may emit blue, red, or green light when illuminated. Other colors may be provided that are easily visible and detectable from the cab.
An operator in the cab may operatively control the light mechanism 314 using one of a plurality of controls in the cab. In one example, the lighting mechanism 314 may be turned on or turned on when a conventional field light is off. In another example, a dusk-dawn sensor may trigger the light emitting mechanism 314. A timer may be set at which the light emitting mechanism 314 is triggered. Other sensors or control features may be utilized to control the lighting mechanism on or off.

In addition, crop divider bars having four or more segments may be used. Thus, the design of the crop divider bar may vary depending on the embodiment.
