The following adverse effects during mowing work for the purpose of sliding left and right
May be removed. That is, the mowing part is located on the left and right
Harvesting on the reciprocating runway if it is arranged over the entire surface
Can work, but in a small double-harvest combine
Has a small number of cutting lines, so the body width is
It is longer and the mowing part is located on one side of the vehicle body adjacent to the driver's seat
The mowing leans to one side of the car body. So, this
Harvesting in the center of the field in a spiral from the surrounding ridge
Reap toward. [0005] In the ridge, the portion where the driver's seat is disposed
So that it does not touch the culm,
Is left. In this mowing work, the first row
In the harvesting process, the unplanted surface is about the width of the driver's seat area
Therefore, the mowing section should be as close to the driver's seat as possible.
Go on. In this case, the crawler on the cutting section side
The mowing work proceeds as it is next to the harvesting culm.
The crawlers, especially in soft fields,
E.g. the neighboring uncut culm may fall down
Threshing and sorting work due to the adhesion of mud to the culm
There has been the disadvantage of becoming more efficient. like this
To eliminate the adverse effects, move the crawler from the adjacent uncut grain culm.
So that the mowing part is closer to the uncut culm side
It is configured to be slidable. On the other hand, the purpose of sliding the reaping unit left and right is
And as stated in JP-B-53-27171
When the aircraft is turned over on the headland,
To reciprocate cutting by sliding
However, in this case, slide the mowing part manually one by one.
Is a great deal of labor, and therefore,
An actuator that slides left and right is required,
Not only does it lead to higher costs, but also
Must be performed, leading to erroneous operation and fuel consumption.
There is also a problem in durability due to repeated riding. [0007] Therefore, the slide of the mowing part is as described above.
When switching between mowing at the ridge and mowing at other times
Configuration that slides manually if it is done only once
It does not require much labor and the number of parts is small.
Can reduce the size and cost of the mowing part.
In conventional technology, it is not possible to achieve these objectives.

There is a high possibility that the case will tilt forward, backward, left and right. [0010] Also, in the aforementioned Japanese Utility Model Laid-Open No. 5-15728,
In the case of a sliding type combine,
The first transmission shaft is directly connected to the force shaft, that is, the cutting input
The shaft case must be close to the base end of the first transmission shaft case.
No. On the other hand, the first transmission shaft case is
Do not interfere with the traveling transmission case etc.
Uh, it must be arranged to some extent ahead. Therefore,
In this case, the cutting input shaft case at the rear end of the cutting section also moves forward.
The entire reaping section must be moved forward.
I will. Further, a pre-processing device such as an elevating device is moved forward and backward and left and right.
