けてある全稈投入型コンバインに関する。[Detailed description of the invention] [Field of industrial application] The present invention includes a raking device for raking the planted grain culm, a reaping device for reaping the raked grain culm, and a raking device for reaping the raked grain culm, and a raking device for reaping the raked grain culm, and a raking device for reaping the raked grain culm. A reaping pre-processing section consisting of a pre-processing head section equipped with a merging device for feeding and merging grains, and a feed case equipped with a rear conveyance device for transporting the harvested grain culm inherited from the merging device toward the threshing device, is connected to the feed case. This invention relates to a full-culm input type combine harvester that is attached to the traveling machine body through the base end of the combine harvester.

に沈下突入するといつた問題がある。[Prior Art] In a full-culm input type combine harvester having the above configuration, when one of the left and right running devices falls into the furrow during wheat cutting work, the machine body tilts to the left and right, and the attitude of the harvesting device changes accordingly. Because of this, there are problems such as the cutting height not being constant in the horizontal direction or the cutting device sinking into the ground.

を設けていた。 Therefore, as mentioned above, even if the machine body is tilted due to the sinking of one of the traveling devices, at least the reaping device can be kept in line with the planting surface, and the pretreatment head section can be operated in a rolling manner relative to the machine body. However, the rolling operation structure of this device is to attach the preprocessing head part to the feeder case (aircraft body) via a fulcrum shaft along the longitudinal axis of the aircraft so that it can freely roll. Regardless of the situation, it is common to construct a pretreatment head that can always be aligned with the planting surface. If the rolling operation of the preprocessing head cannot be performed sufficiently with only the configuration in which the preprocessing head can perform rolling operation via the fulcrum shaft, it is necessary to further ensure that the rolling operation of the preprocessing head cannot be performed sufficiently. A balance biasing spring was provided.
しかし、上記のように前処理ヘツド部が自由ロ

なわれなかつた。
However, in the case where the pretreatment head part is free rolling as described above, the rolling operation relies only on the ground reaction force from the planting surface, so the cutting width is not the same as the one equipped with the above-mentioned merging device. Those with a wide pretreatment head are heavy in weight, and the rolling action cannot be performed smoothly using ground reaction force alone.
本考案の目的は刈幅の広い前処理ヘツド部を持
つものにおいても、円滑にローリング作動できる
ものを、構造を簡素化した状態で行なえるものを
提供する点にある。 An object of the present invention is to provide a device that can perform rolling operations smoothly even in a device having a pretreatment head portion with a wide cutting width, with a simplified structure.

The characteristic structure according to the present invention is that the preprocessing head part is pivoted to the feed case so as to be able to be driven in a rolling manner by a first drive device that is bridged between the two, and the preprocessing head part is supported on the horizontal reference line or The reaping pretreatment section is driven to vertically swing with respect to the traveling machine body by a second drive device which is provided with a rolling control means to maintain a predetermined posture with respect to the ground and is installed across the feed case and the traveling machine body. The feed case side mounting end of the first drive device is fixed to a second drive device mounting bracket provided on the feed case, and the first drive device and the second drive device are configured to extend and contract. The directions are set so that they are located on substantially the same plane along the front-rear direction in a plan view, and the effects are as follows.
つまり、前記前処理ヘツド部をローリング駆動

That is, by providing the first drive device that drives the pretreatment head in a rolling manner, it is possible to cause the pretreatment head with a wide cutting width to perform a smooth rolling operation. Moreover, by adopting this first drive device, it is possible to not only set the pretreatment head section in a posture along the planting surface, but also to set the pretreatment head section in a posture along the planting surface, but also to control the pretreatment head section through the operation of the rolling control means consisting of a gravity-type tilt sensor, etc. It is possible to set the plant so that it is inclined at a certain angle with respect to the horizontal reference line (the planting surface if the planting surface is a horizontal surface).
その結果、前処理ヘツド部のローリング作動を

As a result, the rolling operation of the pretreatment head can be performed more smoothly, and the tilting position can be set as desired.For example, in a field with a planting surface along a slope, if one of the left or right traveling devices sinks further, The pretreatment head can be set in a position along the planting surface.

化を図ることができる。 Moreover, when configuring the first drive device,
Since the attachment end of the first drive device to the feeder case and the attachment end of the second drive device to the feeder case are fixed to the same bracket, the number of parts can be reduced accordingly, and the attachment of the second drive device to the feeder case is easy. If the end is displaced rearward in the longitudinal direction of the aircraft compared to the mounting end of the first drive device, a bending moment will be applied to the preprocessing head corresponding to the distance, and the feeder case itself will need to be reinforced. However, in the present invention, the reaction force of the first drive device acts directly on the second drive device in almost the same direction of expansion and contraction, so the bending moment applied to the feed case can be kept low, and the bending moment on the connecting bracket itself can be suppressed. The moment can also be suppressed to a small value, and parts can be simplified.

バイン。 A pretreatment head section 5 equipped with a raking device 1 for raking the planted grain culms, a reaping device 2 for reaping the raked grain culms, and a merging device 4 for transversely feeding and merging the harvested grain culms in the middle of the cutting width; A reaping pre-processing section 9 consisting of a feed case 8 equipped with a rear transport device 7 for transporting the harvested grain culm inherited from the merging device 4 toward the threshing device 6 is transferred to the traveling machine through the base end of the feed case 8. It is a full culm input type combine harvester attached to the feed case 8, and the pretreatment head section 5 is attached to the first section which is bridged between both the feed case 8 and the feed case 8.
The feed case 8 is pivotally supported by a drive device 21 so as to be driven in a rolling manner, and includes a rolling control means 27 for maintaining the preprocessing head section 5 in a predetermined posture with respect to a horizontal reference plane or the ground.
The reaping pre-processing section 9 is configured to be vertically swingable with respect to the traveling machine body by a second drive device 11 installed over the traveling machine body 10, and the first drive device 21 is mounted on the feed case side. The end is fixed to a second drive device mounting bracket 19 provided on the feed case 8, and the expansion and contraction operation direction of the first drive device 21 and the second drive device 11 is set approximately along the front-rear direction in plan view. A full-culm input type combine harvester that is set up in a row on the same plane.
