DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain raising apparatus provided with a raising case for raising and supporting uncut kernels.

[0002]

2. Description of the Related Art Conventionally, a raising case is formed of a case main body and a detachable upper cover, so that maintenance of the raising case can be easily performed only by attaching and detaching the upper cover.

[0003]

In the prior art, when the auxiliary raising case is provided separately from the raising case, the auxiliary raising case is disposed on the front side of the raising case, that is, on the upper cover side. As a result, the upper cover of the raising case cannot be easily attached or detached, and there is a problem that the maintainability of the raising case deteriorates.

[0004]

However, according to the present invention, there is provided a combine having an auxiliary raising case for protruding a falling culm standing tine in the advancing direction of the fuselage on the front side of a raising case for protruding the raising tine in the lateral direction of the fuselage. In the grain stem raising device, the rear end of the weeding arm is detachably attached to the front end of the mowing frame supporting the raising case, and a weeding plate is attached to the front end of the weeding arm, and the weeding arm is integrally attached to the weeding arm.
On the grass mounting bracket, one side below the auxiliary raising case
Bracket attached to the part with two bolts
Fasten and attach one bolt of the weeding board mounting bracket.
Hole is formed in an arc-shaped long hole, and the
Erected along the front of the raising case, and
Use the other bolt as a fulcrum when loosening the bolt
Move the upper part of the auxiliary raising case by a predetermined range
When the maintenance of the raising case is performed and the auxiliary raising case is
By lowering the part in the advancing direction of the fuselage, the upper cover of the raising case can be easily attached and detached without obstructing the auxiliary raising case, and the maintenance property of the raising case can be prevented from being deteriorated by the auxiliary raising case. The auxiliary raising case can be easily lowered by releasing the bolts, and the auxiliary raising case can be made to stand on its own in a lowered state, so that the auxiliary raising case can be easily handled during maintenance of the raising case.

A driving case is provided on the upper part of the auxiliary raising case, and the end of the driving case is detachably mounted on the upper front surface of the raising case. The driving case is separated from the raising driving shaft of the raising case when the auxiliary raising case falls down and is connected when returning. By providing the input shaft to the drive case, the input shaft and the drive shaft, which is the transmission shaft to the auxiliary raise case, can be automatically separated and connected by the fall and return operations of the auxiliary raise case. The auxiliary raising case can be easily handled at the time of maintenance.
