れる反面次のような欠点があった。A conventional reaping machine, for example, the reaping machine described in Japanese Patent Publication No. 51-9655, processes the entire pre-processing section equipped with the reaping device as described above based on the detection result of a ground sensor installed near the reaping device. Since the main frame was only used to raise and lower the machine around the horizontal axis on the machine side, the detection position and the cutting position were close to each other, making it possible to accurately align the cutting height of the culm, but it had the following drawbacks: there were.

に現われるのである。There is a risk that the weeding bodies, etc., which are slumped in front of the reaping device in the pre-processing section, may plunge into the ground and be damaged when the mowing height is automatically controlled to follow the unevenness of the ground. However, this drawback is especially noticeable when the ground is uneven.

する。The present invention was developed in view of the above circumstances, and when automatically controlling the cutting height, it prevents the pretreatment section from penetrating into the ground regardless of the degree of unevenness of the ground, and prevents damage to the pretreatment section. The purpose of the present invention is to provide a reaping/harvesting machine that can avoid such problems.

る。Figure 1 is a front side view of the combine harvester, in which a planted culm lifting device 1 is installed at the front of the machine, a reaping device 2 is installed near the ground behind this pulling device 1, and At the rear, there is a threshing device 3 mounted on the rear of the machine that collects the husks that have been pulled up and cut.
A rear conveyance device 5 for delivering the cut husk to a feed chain 4 attached thereto is disposed, and these, the lifting device 1, the reaping device 2, and the rear conveyance device 5 constitute a preprocessing section 6.

いる。The main frame γ of this pre-processing section 6 is the traveling body 16.
The pretreatment section 6 is rotatably mounted around the horizontal axis P1, and the bending link 9 is swung by each expansion and contraction movement of the first hydraulic cylinder 8, so that the pretreatment section 6 can be lowered by the drive valve. It is configured.

ることにより伸縮作動すべく構成されている。Furthermore, the expansion and contraction operation of the first hydraulic cylinder 8 is performed by operating a hydraulic control valve (not shown) with a rotation movement of the first sensor 10 disposed directly below the reaping device 2 above a certain level. It is configured as follows.

処理部6に設けられた刈取装置2を地面一定位置に保持
すべく構成されている。That is, the first sensor 10 supports the lower end of the pulling device 1 and has a grass cutting function.
It is pivoted so as to be able to move freely in two rotations, and is biased so as not to rotate downward, so that the 10° tip of the first sensor is in contact with the ground;
In a neutral state in which the arm 10a extending from the base end of the sensor is located at an intermediate position between the ascending contact S1 and the descending contact S2, the arm 10a is installed in the preprocessing section 6 without extending or contracting the first hydraulic cylinder 8. It is configured to hold the harvested reaping device 2 at a fixed position on the ground.

なるように構成されている。On the other hand, in the lifting device 1, the lifting device support rod 13 is swung around the horizontal axis P3 at the lower end of the main frame 1 by the expansion and contraction operation of the second hydraulic cylinder 12. The structure is such that the distance between the weeding body 14 attached to the ground and the ground is approximately constant.

ぼ一定高さ位置に位置されるべく構成されている。That is, a second sensor is pivotally attached to the weed splitting body 14 so as to be biased to rotate downward about the horizontal axis P4, and the arm 15a of the second sensor 15 is connected to a rising contact S4, a descending contact S,
When the weeding body 14 is located at an intermediate position between the two, the grass divider 14 is configured to be located at a substantially constant height from the ground.

起し装置1の下端の分草体14もこの直下の地面形状に
適合させて一定高さ位置に保持されるのである。According to such a configuration, when the reaping device 2 is on uneven ground, the first sensor 10 operates to adapt the reaping device 2 to the shape of the ground directly below the reaping device 2 and hold it at a constant height position, and the raising device 1 The grass divider 14 at the lower end of the grass is also adapted to the shape of the ground directly below and held at a constant height.

形状に拘らず個々に適正な高さに位置されて、分草、引
起し、刈取り作用を適正に行い得るものでありながら、
不測に地面に衝突させて、これら損傷することもない。Therefore, the lower end of the reaping device 2 and the lower end of the pulling device 1 are individually positioned at appropriate heights regardless of the ground shape, so that the grass cutting, pulling, and mowing operations can be performed appropriately.
There is no chance of damage caused by accidental collision with the ground.
又、前記第1及び第2センサー10.15の形状をソリ
状に形成してもよい。Further, the first and second sensors 10.15 may be formed into a sled shape.
