(57) [Summary] [Purpose] The operator's seat in the combine has a wide field of view even when the operator is seated so that the harvesting work can be performed reliably. [Structure] The driver's seat 6 is arranged in the rear upper part of the mowing section C and in the front upper part of the engine room 8, and the driver's seat 6 is configured to move up and down in conjunction with the raising and lowering of the mowing section C.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of the driver's seat for more reliable harvesting work of the combine.

[0002]

[Prior art]

 As shown in FIG. 6, the driver's seat of the conventional combine is placed on the engine room in the front part of the body frame 31, and the cutting part C is protruded from the side of the driver's seat 28 to the front. Was configured to be able to move up and down.

[0003]

[Problems to be solved by the device]

 However, the driver's seat 28 of the conventional combine B is fixed above the engine room so that the driver's seat is located as high as possible so that the front part of the mowing section C can be seen. The upper part of the device is obstructed and the sward plate 30 is hardly visible. Especially, the sizing plate on the side opposite to the seat is invisible and the operator's experience determines whether or not to perform the work, or the operator is standing or standing upright. I was working with the body leaning forward. Therefore, if you work with intuition, you will be left uncut if the line is bent, and if you stand or bend forward, you will be very tired. There was a risk of being shaken off.

[0004]

[Means for Solving the Problems]

 The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below. That is, the combine driver's seat is arranged in the upper rear of the mowing section and in the upper front of the engine room, and the driver's seat is raised and lowered in conjunction with the raising and lowering of the mowing section.

[0005]

[Operation] The operation of the present invention will be described. When the support frame 24 projecting forward from the pivot shaft 18 provided in the main body of the combine A is rotated by the expansion and contraction of the hydraulic cylinder 27, the driver's seat 6 is simultaneously moved up and down via the suspension 25 connected to the support frame 24. The driver's seat 6 is moved up and down in parallel by the parallel link 23 connected to the rear part, so that the operator's seat is located in front of the conventional one, and the operator can check the front end of the mowing part C while sitting. It is possible to steer and operate with a wide field of view.

【Example】

 The problems to be solved and the means for solving the present invention are as described above. Next, a specific configuration of the present invention will be described with reference to the accompanying drawings. Fig. 1 is an overall right side view of the combine, Fig. 2 is a left side view of the combine, Fig. 3 is a right side view of the same in which the mowing section is raised, Fig. 4 is a left side view of the same, and Fig. 5 is a plan view of the mowing section and the driver's seat. It is a figure.

Explaining from the overall configuration, the combine A mounts the machine frame 2 on the crawler type traveling device 1, projects the cutting section C in front of the machine frame 2, and the cutting section C is located at the front end. The weeding board 10 is projected, the raising device 3 is erected at the rear part of the weeding board 10, and the upper transporting device 12, the lower transporting device 13, the auxiliary feeding device 14, etc. are arranged in the cover 4, and the lower cutting A cutting blade 11 is horizontally provided on the frame. A threshing device 5 with a handling barrel installed in the rear of the mowing section C, a sorting device provided in the lower part thereof, a driver's seat 6 is arranged in the rear part on the right side, a Glen tank 7 in the rear part, and an engine room 8 in the lower part in the rear part of the driver's seat 6. Is provided, and a discharge auger 9 is provided on the front portion from the rear end so that the fine grains stored in the grain tank 7 can be discharged.

Next, the mounting structure of the driver's seat and the reaping part C, which are the main parts of the present invention, will be described. The front column 20 on which the steering lever 20a is projected and the monitor and the like are raised in front of the operating seat 6. It is provided in the upper left part of the cover 4 above the sushi device 3, a side column 22 is attached to the side of the driver's seat 6, and a working lever, a raising / lowering lever of the reaping part, a speed change lever, etc. are provided. At the lower front part of step 6, step 21 is projected. A parallel link 23 is pivotally connected to the rear portion of the driver's seat 6, a rear end of the upper link 23a of the parallel link 23 is pivotally connected to the front end of the Glen tank 7, and a rear end of the lower link 23b is above the engine room 8. The driver's seat 6 can be moved up and down in parallel, and a reinforcing link 32 is provided between the rear end of the upper link 23a and the rear end of the lower link 23b. The upper portion of the front end of the Glen tank 7 is configured so as to bulge above the engine room 8 by disposing the driver's seat 6 above the front of the engine room 8 to expand the capacity.

An upper end of a suspension 25 is pivotally connected to a lower portion of the driver's seat 6, and a lower end of the suspension 25 is pivotally connected to a middle portion of the upper support frame 24a. The upper support frame 24a has a triangular structure in a side view to improve rigidity by fixing the lower support frame 24b and the front support frame 24c to each other, and the upper support frame 24a and the lower support frame 24b are arranged on both left and right sides. The rear end is fixed to the pivot shaft 18 in a π shape in a plan view, and the pivot shaft 18 is rotatably supported on a support stand 16 that is erected on the front portion of the body frame 2. An input shaft 18a is horizontally mounted on the. The lower support frame 24b is internally provided with a transmission shaft for transmitting power to the mowing section C, and a hydraulic cylinder 27 is interposed between the midway portion of the left lower supporting frame 24b and the machine frame 2 to cut the mowing section C. Can be moved up and down, and a mowing frame 26 is fixedly provided at the front end. A transmission shaft for driving the raising device 3 is installed in the front support frame 24c.

With this configuration, when the hydraulic cylinder 27 is extended to raise the cutting section C 1, the driver's seat 6 is raised via the suspension 25, and at this time, the driver's seat 6 is moved by the parallel links 23a and 23b. Are raised in parallel, and the suspension 25 can absorb vibrations during work. Then, when the hydraulic cylinder 27 is contracted and the mowing section C is lowered, the driver's seat 6 moves forward in parallel, and its position becomes the upper rear of the mowing section C, the field of view expands, and the tip of the grass plate 10 is reached. You can see it.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. First, the driver's seat is projected more forward than in the past, and it is configured to move up and down in conjunction with the reaping section, which greatly improves the front field of view both during mowing work and moving. The operator will be able to perform the mowing work while sitting down.

Secondly, since the driver's seat could be located in the front, the Glen tank can be overhung above the engine loom, which not only increases the capacity of the Glen tank but also increases the total length of the combine. It is short and allows the overall height of the Glentank to be low, and there is also space around the engine, which allows the engine to be cased and soundproofed.

Thirdly, the triangular support frame for connecting and supporting the reaper is widened at the rotation fulcrum and is supported by both ends of the combine fuselage, so that the reaper is stable and strong. In addition, by arranging the hydraulic cylinder on the seat side, it is possible to easily attach and detach when the cutting part is open, and the operation for turning to the side is easy. It will be possible.
