Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine having an auger that moves between a storage position and a discharge position and above the driver's seat.

[0002]

2. Description of the Related Art In a combine in which grains in a grain tank are discharged to a transportation means such as a truck through an auger, the discharge positions of the grains by the auger are located on the left and right side surfaces of the combine and at the rear ( It is set in 3 places). Then, the auger swivels leftward (counterclockwise) with respect to the combine from the storage position to the discharge position, and swivels rightward (clockwise) from the discharge position to the storage position. Was configured as. That is, the auger swivels above the threshing section and the culm section.

Therefore, since there are no obstacles in the turning range of the auger other than the auger receiver arranged at the storage position for turning and lifting the auger, if the auger receiver is separated from the auger receiver, The auger can be turned at an arbitrary angle in its ascending direction and can be moved up and down at an arbitrary position.

Generally, in the mowing work in a field, the combine is rotated counterclockwise while rotating from the outside to the inside of the field. Therefore,
The road on which the grain transporting means such as a truck travels is located on the right side in the traveling direction of the combine.
Therefore, the discharge position where the auger discharges the grain is often the right side or the rear part in the traveling direction of the combine, and it is extremely rare to discharge the grain on the left side of the combine.

Assuming that the grain discharging position of the auger is on the right side in the traveling direction of the combine, if the auger is turned counterclockwise, the turning angle of the auger increases, and the auger moves from the storage position to the discharging position. The turning time of
This will reduce work efficiency. Therefore, there has been proposed a combine in which the auger is swung clockwise (clockwise) from which the swivel angle from the storage position to the discharge position is reduced to improve work efficiency.

[0006]

When turning the auger clockwise, the auger passes above the combine driver's seat and a grain tank for temporarily storing grains. Therefore, if the auger is swung at an arbitrary raised position or moved up and down at an arbitrary position as in the conventional case,
The auger collides with the driver's seat and the Glen tank, which is extremely dangerous in work.

In view of the above circumstances, it is an object of the present invention to provide a combine in which the auger is turned clockwise to improve work efficiency and work safety.

[0008]

9) A combine range in which a restriction range (H) for prohibiting the descent is set, and the turning position of the auger (19) detected by the turning position detection means (45) is within the restriction range (H). In some cases, the combine position detection means (46) is provided with a control means (50) configured to permit the descent of the auger (19) when the auger (19) is detected. It is in.

That is, when the upper limit switch 26 does not detect that the auger 19 is at the rising end,
The turning of the auger 19 is prohibited. The auger 19 can be raised at an appropriate timing.

[0045]

According to the first aspect of the present invention, when the auger is in the regulation range where the auger is prohibited from descending, the storage position detecting means for detecting that the auger is in the storage position or the position corresponding to the storage position is provided. Since the descent of the auger is permitted when the auger is detected, the auger can be reliably stored in the auger receiver, and the work efficiency can be improved. Further, even if the auger descends, it does not come into contact with the worker, and the work safety can be improved.

According to the second aspect of the present invention, when the upper limit detecting means does not detect the auger, the turning of the auger is prohibited, so that the turning auger has a Glen tank or an operation within its turning range. Without touching your seat,
Work safety can be improved.
