In addition, the normally self-releasing type combine, a threshing unit is provided on the left side of the traveling body having left and right traveling crawlers, a grain tank is provided on the right side of the threshing unit, a cab is provided in front of the grain tank, The mowing unit is disposed on the left side of the cab and in front of the threshing unit. 2. Description of the Related Art A combine in which a mowing unit slides in the left-right direction of a machine, and has a dustproof cover for preventing dust generated in the mowing unit from scattering to a driving operation unit having a driver's cab. A structure in which the dustproof cover is fixedly supported on the frame integrally extended from the raising case of the mowing portion, and the dustproof cover slides left and right integrally with the mowing portion, and a frame integrally extended from the threshing portion behind the mowing portion. There is a structure in which a dust-proof cover is fixedly supported, and the dust-proof cover is held at a fixed position irrespective of the left and right sliding of the mowing part. [0003] In the mounting structure of the dustproof cover, in the former case, the position of the dustproof cover with respect to the operation unit changes as the reaping unit slides to the left and right, and a certain dustproof effect cannot be obtained. At the same time, it is necessary to perform a difficult dust-proofing process to fill a gap between the dust-proof cover and the operation unit that changes with the left and right sliding of the mowing unit. On the other hand, in the latter case, when the reaper is turned up and down, the dustproof cover is provided with a certain distance so that the dustproof cover does not interfere with damage, and the dustproof cover follows the up and down rotation of the reaper. The dust-proof cover must be turned up and down, and the dust-proof cover cannot be extended to the front of the mowing part, so that the mounting structure of the dust-proof cover is complicated and only a low dust-proof effect can be obtained. [0004] It is an object of the present invention to provide a dustproof cover so that dust generated in a sliding type mowing part can be surely prevented from scattering to a driving operation part having a driver's seat. [0005] A combine harvester according to the present invention is configured such that the reaper is slidable in the lateral direction of the machine at the tip of a reaper connecting pipe extending obliquely downward and forward from a vertical pivot of the reaper. And a combine harvester including a dustproof cover for preventing dust generated in the mowing portion from scattering to the driving operation portion side having a driver's seat.
A cutting side panel stretched along the left side edge of the driving operation unit is fixed to a cutting unit that is rotatable up and down and that is not interlocked with the lateral sliding of the machine body, and is horizontally mounted above a raising case of the cutting unit. The support rod is integrally extended from the front end of the cutting side panel, and the right edge of the dustproof cover is fixedly supported on the cutting side panel, and the front edge is fixedly supported on the support rod. By supporting the intermediate portion slidably on the raising case side, the support rod cannot be supported in a cantilever manner. Therefore, the support strength of the dustproof cover is increased, and the dustproof cover can be stably mounted. This is a preferred embodiment. Therefore, according to the combine harvester of the present invention, the dust cover is fixedly mounted at a fixed position on the side of the reaper so as not to slide right and left integrally with the reaper. Even if you slide left and right, the dustproof cover is always in a fixed position, and you can obtain a high dustproof effect constantly,
It is possible to reliably prevent dust generated in the sliding type mowing part from scattering to the driving operation part having the driver's seat. An embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a plan view showing a mounting structure of a dustproof cover, FIG. 2 is an overall side view of a self-removable combine, and FIG. 3 is an overall plan view of the combine, in which (1) includes a left-right traveling crawler (2).

A vertical front bearing pipe (58) fixed to the front end of the rotating frame (56) is rotatably fitted to and supported by the outside of the front support shaft (55), and the cutting unit (7) is connected to the cutting upper connecting pipe (51). ) And the rotating frame (56), the rotation of the cutting unit (7) about the slide pipe (40) as a fulcrum is restricted by the cutting upper connecting pipe (51) and the rotating frame (56), The rotating frame (56) is configured to rotate in the horizontal direction following the slide of the mowing part (7). As shown in FIGS. 1 and 6, the front and upper right side surfaces of the mowing portion (7) are covered to prevent dust generated in the mowing portion (7) from scattering to the driving operation portion (11). And a dustproof cover (59) made of transparent resin. The dustproof cover (59) has its lower right edge detachably attached to the mowing side panel (52), and both ends are brackets (60) (6).
1) two parallel support rods (6)
2) is provided, the right bracket (60) is bolted to the front end of the cutting side panel (52), and the support rod (62) is laid obliquely above and behind the horizontal transmission pipe (49) in parallel with it. A support rod (62) is stretched inside the front edge side of the dustproof cover (59), and the left front end of the dustproof cover (59) is detachably attached to the left bracket (61).
Dustproof cover (59) at a fixed position regardless of the slide
Is configured to be fixedly supported. Further, a support plate (63) is provided to extend from the intermediate portion of the horizontal transmission pipe (49) to below the support rod (62), and a pair of front and rear bolts (64) and spacers (65) are provided on the upper surface of the support plate (63). ), A middle portion of the support rod (62) is slidably held on the upper surface side of the support plate (63) by a washer (66) which is tightened and fixed, and a support rod fixed to the middle of the sliding lateral transmission pipe (49). (62) The intermediate portion is configured to be supported. This embodiment is constructed as described above, and moves the cutting part (7) to the right slide end position (the solid line position in FIGS. 3 and 5) when performing a ridge or middle splitting operation. The left and right traveling crawlers (2) prevent stepping on the uncut kernels, and during normal work where the right side of the machine is already cut and the left side of the machine is not cut, the cutting unit (7) is moved to the left slide end position. (The position of the virtual line in FIGS. 3 and 5)
The left traveling crawler (2) is moved as far as possible from the uncut kernels to prevent the traveling crawler (2) from pushing the soil onto the uncut kernels. Dust generated in the mowing portion (7) is removed from the left and rear open surfaces of the dustproof cover (59) by the mowing portion (7).
The dust is discharged toward the outside or to the left of the left side, and does not scatter to the driving operation unit (11) side. Even if the mowing part (7) slides right and left, the dust cover (59) does not move and is always at a fixed position with respect to the driving operation part (11), so that dust does not scatter to the driving operation part (11). Dustproof cover (59)
When the mowing part (7) is raised and lowered, the mowing part (7) moves up and down integrally with the mowing part (7). Therefore, it is not necessary to attach the mowing part (7) to the upper part of the mowing part (7) with a certain distance. And the upper part of the front part of the mowing part (7) can be covered, so that a high dustproof effect can be obtained. Further, since it is not necessary to rotate the dust cover (59) up and down following the elevation of the cutting unit (7), the mounting structure of the dust cover is simplified. The dust cover (59) and the operation unit (1)
Since the gap with (1) is very small and constant, the dust-proof treatment of filling the gap with vinyl, rubber, or the like can be easily performed. Also, a mowing side panel (52) for attaching a dustproof cover (59).
Is also stretched along the left edge of the driving operation unit (11), and the position of the driving operation unit (11) does not change even if the cutting unit (7) is slid left and right. Can also be installed. As is apparent from the above embodiment, the present invention is directed to a cutting connection pipe (29) extending obliquely forward and downward from the vertical pivots (31) and (32) of the cutting unit (7). The cutting section (7) is slidably supported in the left and right direction of the machine body at the tip, and dust generated in the cutting section (7) is exposed to the driver's seat (1).
In a combine harvester equipped with a dustproof cover (59) for preventing scattering to the side of the operation unit (11) having a cutting side (0), a cutting side stretched along the left edge of the operation unit (11). The panel (52) can be turned up and down
The mowing side panel (52) is fixed to a mowing portion that does not interlock with the lateral movement of the machine body, and a support bar (62) that extends above the raising case (18) of the mowing portion (7).
The dustproof cover (59) is extended integrally from the front end, the right edge of the dustproof cover (59) is attached to the cutting side panel (52), and the front edge is attached to the support rod (6).
2), the dustproof cover (59) is fixedly mounted on the cutting section (7) side so as not to slide right and left integrally with the cutting section (7). Even if 7) slides left and right, the dust-proof cover (59) is always at a fixed position, and a high dust-proof effect can be obtained constantly, and dust generated in the sliding-type mowing part (7) is removed from the driver's seat (10). This has a remarkable effect that it can be reliably prevented from scattering toward the driving operation unit (11) having the above.
