Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a driver's seat in a combine harvester where a worker is seated.

When operating a combine harvester, it is generally installed at a high position on the side of the reaping pan, and allows the operator to sit in the driver's seat and perform operations such as Isoko's gravel harvesting, meli removal, and threshing. At the same time, Iso 8 moved out of the row of bamboo killing rows.
In order to prevent the formation of residue or the roller running the full distance stepping on it and colliding with the loss, move in the direction of travel of the entrance, that is, the frontmost branch of the machine and the grain pole. It is necessary to constantly monitor the relative position of the However, if the operator sitting in the driver's seat is too low or too close to the vehicle, the operating device often obstructs the driver's sight. Therefore, conventionally, driving
Depending on the volume of the worker, the height can be adjusted either in a horizontal direction or in an inclined direction that increases as the sword is drawn. I am trying to adjust it so that it is positioned high and forward.

However, with large aircraft, you may not be able to see the tip of the splitter body even if you move the operating g forward and raise it. There are many ridge stands that allow you to look in the direction of the cuttings.
In contrast, in the conventional driver's seat, the seat, the backrest, and the elbow lamppost with the reaping operation lever move as one, so the driver sits shallowly and lies in the mid-bottom position. Moreover, the backrest is far away from the back, making the worker's posture unstable and making it difficult to operate levers, etc.

The present invention has the above features and features a horizontal seat that is raised and lowered by operating a height adjustment device, and a backrest that goes up and down and moves back and forth in accordance with the raising and lowering movement of the seat. J:! 7.7 - To provide a combine harvester driver's seat that makes it easy for all women to operate the lever while seated regardless of the height of the toe. Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 and 2 show an embodiment of the uninvented combine harvester seat, Figure 1 is a side view of a combine harvester in which this invention was actually used, and Figure 2 is a side view of the driver's seat. . In the figure,
A combine harvester 1 is equipped with a pair of left and right running rollers 2, and on a running frame 3 connected to the combine harvester 1, a frame 5 of a threshing machine 4 extending over the entire length of the harvester is located on the paper backing in FIG. It's equipped. In front of the threshing machine 4, a reaper, generally designated by reference numeral 6, is pivotally supported on a bearing at the front end of the threshing machine 4, and is swung by a hydraulic cylinder to form a clipper-shaped cutting blade. The cutting height according to step 7 is adjusted. The reaping machine 6 is equipped with a plurality of dividing rods 8 that support the cutting blades γ and extend from the front to the rear. Grass plant 9 moving through the rows
Each of them is standing firm. The reference numeral 10 is a lifting device for raising the grain culm by transporting the tip of the grain culm that has been raked by the weeding body 9. In the raising case 11, there are many lugs 12. A hoisting chain running at regular intervals is suspended. A grain culm feeder t (not shown) is provided between the raising case 11 and the threshing machine 4 to transport the grain culm cut by the cutting blade T toward the threshing machine 4. In the frame 5 of the threshing machine 4, there are provided a handling cylinder for threshing the grain culms transferred from the grain culm conveying device to the feed chain, and a sorting device for sorting out the threshed grains for slaughter. A hopper 13 with a paddy tank is disposed on the first side of the frame 5 for discharging one grain of grain for bagging. Further, at the rear of the frame 5, there is disposed a waste straw processing device 14 equipped with a cutter and the like for cutting grain culms, that is, waste straw discharged from the seven frames 5 after threshing.

On the first front side of the threshing machine 4, drive sources for each part and an engine 1 and 2 are housed in an engine room 15.
A driver's seat, generally designated by reference numeral 16, is disposed on the upper part of the front part of the vehicle, and is supported by a small frame 17. That is, a pair of left and right brackets 18 fixed on the small frame 17 and a pair of left and right brackets 19 erected in front thereof include the seat 20 of the driver's seat 16 and the backrest 21.
and armrest 22t - a link mechanism 2 with a pair of five stones shown as an example of an interlocking device that supports and interlocks the movements of
3 is waiting. That is, the bracket 18 has
Link 2 of length = -n with mutually meshing gears 24.25
6.27 is pivotally supported, and the playable part of the link 27 on the left stone is connected by a rotating pivot 28. In addition, the left and right links 26 are connected at a position in the center of the long link 26 where the distance from the center of rotation of the link 26 is equal to the distance between the rotating groove of the link 27 and the pivot shaft 28. Axis, 1i! 9 is a bearing 2, and a threaded portion 32 of a screw thread 32 which is integrally formed in the center of the pivot shaft 29 and which is rotatably supported in a bearing 31 of the large part of the pivot shaft 28 is screwed. They are together. Further, both pivots 28, 29 and the lower end of the seat 20 are connected by connecting links 33, 34, and a handle is fitted into the square head of the screw head 32 and rotated. As a result, the distance between the two pivots 2B and 29 expands and contracts, and the mid-height seat 20 maintains a horizontal position and moves up and down in the vertical direction via the links 6.27 and 33.34. . Next, the left stone bracket 19 has a link 3 that is approximately the same length as the longer link 26.
5 is pivotally supported, and this link 35 and the link 26
A pair of right and left interlocking plates 36 are pivotally attached to the free end portions of the two. The backrest fL, 21, which has a medium-high shape and allows the back to lean against when viewed from the seat 20, is fixed to the left and right support plates 36 and formed integrally, and the seat 20 is indicated by a solid line in the figure. When the seat 2o is descending as shown, the rear end of the seat 2o is raised slightly obliquely with its lower end face facing the upper front. Also, when the seat 20 is raised to the position indicated by the chain line in the figure, the movement of the link mechanism 23 causes the L9 backrest A21 to rise together with the seat 20, and the upper surface of the seat 20 is almost raised. Sheet 2 while making sliding contact
It is composed of two sections that move forward toward the middle and upper part of the o. Furthermore, when sitting on the seat 20, the right direction is 1ii.
11, a water-cone-shaped armrest 22 is fixed to the upper end of the support plate 26 integrally with the entire rear layer, and is integrated with the 2v1 backrest n21 to allow vertical movement and back-and-forth movement. It is configured to do so. This armrest 22 is connected to a hydraulic system and is connected to a hydraulic system for raising and lowering the reaping machine 1o. In the front, an operating device 38 equipped with various operating levers is installed upright in front of a stew knob 39.

A worker 3 is at a combine harvester configured as described above.
9, sit on the seat 20 with his back resting on the backrest n-21 of the driver's seat, and operate the operating levers of the operating device H and the operating lever 3T of the armrest 22 to turn the machine. Make it run and operate the equipment in each part. As the machine progresses, the culms in the field that have been divided by the weed cutting body 9 are erected by lifting and transporting the spear tips by the pulling device 10, and the root parts are cut by the cutting blade T. nru. The harvested husks are transferred to a grain culm conveying device:
The grains are transported to the threshing machine 4 and threshed through the hopper 13 after sorting.
At the same time, the waste straw is cut in a waste straw processing device t14 and scattered on the field.

When driving on the road, the operator is seated in the driver's seat 160.
Lower the sheet 20 gold to the solid line position in Figure 2, and
Put #c on the top and lean on the backrest A21,
Fully steer the aircraft while looking directly ahead. When you arrive at the field and start all the holding work, put a hole in the square head of the screw keyaki 32.
When the handle fc is fitted and rotated, the threaded portion of the threaded rod 32 and the female thread 3° are engaged, and the distance between the pivots 28 and 29 is shortened, and the link 26.2γ stands up as shown by the chain line in the figure. The seat 20 is then raised to the position indicated by the chain line through all the connecting links 33 and 34. At this time, the support plate 36 rises diagonally upward due to the action of the links 26 and 35, so the backrest A21 integrated with the backrest also rises diagonally upwards, and the position of the backrest A21 and the seat 20 is aligned. VC＞The back is also 7 lengths J″L21
In addition, the armrest 22 integrated with the support plate 36 also rises diagonally upward, and the relative position of the backrest A21 and the armrest 22 changes as the seat 20 rises. It doesn't change. In this way, after turning the driver's seat 16 and 7, he takes a seat at seat 20Vc and begins harvesting work, but since the backrest n21 is moving forward, the upper back is also closed. Let's hang sheet 20
When seated on the vehicle, the worker 39 has a shallow height of 9, and the worker 39 has a higher V than when driving on the road, so the worker 39 occupies the position indicated by the reference numeral 39 in FIG. That is, in the case where the seat 20 and the backrest A21 rise together as in the conventional case, the seat 20 and the backrest A21 rise as a unit, as shown in the first part by the reference numeral 39B).
My back could not reach the backrest A21 unless I hung it deeply on 2G, but when I hung it shallowly and took a half-waisted posture, my back was too tall for A21.
It will arrive at 21. On the other hand, as is clear from the figure, when the worker monitors the cutting of the culm by the weed cutting body 9, the operator should keep his or her eyes as high and forward as possible since the operating device 38 is within the line of sight. It is easier to monitor the branching body S in a meeting where you can see clearly, that is, if you hang shallowly and take a half-way posture, but if there is no equipment, it is indicated by the code 39! When the sea urchin is in a half-waisted posture, the back motel 21 moves forward and touches the back, making the posture extremely stable. Since the armrests 22 move forward together with the seat back 321, the relative position f between the 39 workers who are hanging shallowly and the operating lever 3T is the same as the seat 2.
It does not change even if 0 increases, and can always be made to occupy the position i11 that is easy to operate.

Two things are clear from the above explanation! Inventively, the combine harvester's driver's seat has a horizontal seat that can be raised and lowered by operating a height adjustment device, and a back that can be raised and lowered and moved back and forth in conjunction with the raising and lowering of this seat. By configuring the armrest with a dual-purpose operation box, the seat can be lowered and hung deeply when driving on the road, or it can be raised and hung shallowly so that the grass can be clearly seen during harvesting. Even when you are in a half-waisted posture, the backrest moves forward and lands on your back, making your posture extremely stable and allowing you to work for long periods of time.Fourly, the field of view is wide and work safety is ensured. can be ensured. In addition, since the armrests move forward and backward in unison with the backrest, the relative position of the operating lever and the backrest does not change regardless of the height of the seat. Operation always:! 1. It is extremely easy to use, and 2. operability and work safety are significantly improved.
