I have. The connecting wire (driving means) 20 has one end connected to the end of the parallel link mechanism 12 of the weeding rod 4, the other end connected to the lifting frame 13, and a connection in synchronization with the lifting and lowering of the second reaper 11. The grass rod 4 can be moved up and down.

きるものである。The direction sensor 21 is provided on the weeding rod 4 to control the direction of the undercarriage 2 along the culm row in the field. If the weeding rod 4 is configured to be able to travel on the ground surface reference irrespective of the elevating operation of the pretreatment device 9 as shown in FIG.
No. 1 is able to contact the base of the cereal stem row to reliably perform the detection operation.

る。Next, the operation will be described. First,
The traveling device 1 is operated while driving the rotating parts of the body to move the chassis 2 forward, and the combine operation is started. Then, the cereal culm in the field reaches the rotating raking reel 6 which is weeded by the weeding rod 4 at the front and is scraped backward. And the culm is cut by the cutting device 5,
Under the action of the scraping auger 7, it is collected in an intermediate portion, passed on to the conveyor 8 and supplied to the threshing machine 3 behind.
【００１８】そして、穀稈は、脱穀機３によって脱穀処

さに保持されている。The culm is subjected to threshing by the threshing machine 3. On the other hand, the culm remaining on the field with the upper part cut off is cut off by the second cutting device 11 driven via the transmission shaft 17 and discharged to the field. By the way, during the above work, the second
The harvesting height of the mowing device 11 is detected by the ground contact sensor 18, and the control valve 19 is switched based on the signal, and is constantly maintained at a constant height via the hydraulic cylinder 16.

は、刈取装置５に高刈りをさせるために、上昇した位置
にあるが、分草杆４は、上述のように地表面に沿った状
態で進行している。For this purpose, the weeding rod 4 at the front part operates in synchronization with the second mowing device 11 via the connecting wire 20 to ensure the weeding while maintaining a constant distance from the ground surface. The action can continue. In this case, the pre-processing device 9
Is in the raised position in order to make the reaper 5 perform high cutting, but the weeding rod 4 is traveling along the ground surface as described above.

沿った高さを保って前進できる構成にしたものであるか
ら、穀稈の分草作用が極めて確実に出来る特徴がある。Therefore, since the direction sensor 21 is provided at the weeding rod 4 and is at a low position, the direction sensor 21 has the characteristic that it can act on the root position of the cereal stem and reliably detect the cereal stem row. As described above, in order to make the mowing device perform high mowing, the weeding rod, which has not been able to function sufficiently in a state where the mowing device has been raised to a high position together with the pretreatment device, is synchronized with the second mowing device on the ground surface. The structure is such that it can move forward while maintaining the height along the line, so that there is a feature that the weeding action of the cereal stem can be extremely reliably.
【００２１】特に、分草杆は、別体の制御機構を設けな

作用出来て穀稈列の検出が確実にできるものである。In particular, since the weeding rod adopts an interlocking structure that synchronizes with the second reaper without providing a separate control mechanism, the structure can be simplified. Also,
As shown in the embodiment, when a culm contact type directional sensor is provided on this weeding rod, the directional sensor can act on the stem of the cereal culm and reliably detect the culm row. It is.
