Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for threshing and sorting a grain stalk cut in a cutting section in a threshing section.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Application Laid-Open No. 59-110542 and Japanese Utility Model Application Laid-Open No. 60-36046, a grain tank is opened to the outside of the machine around the vertical axis or stored inside the machine. There was a technique for attaching a lock member for fixing a grain tank to a storage position.

[0003]

In the prior art, a belt is stretched between the front end of the lower conveyor at the bottom of the grain tank and the rear side of the driver's seat to transmit the driving force from the machine side, so that the lock is locked. Even if the fixing of the member is incomplete, the grain tank is easily supported at the storage position by the tension of the belt, and it is difficult for an operator to detect the abnormality of the lock member early,
Therefore, when the aircraft leans toward the tank with the grain remaining in the grain tank, the grain tank moves toward the outside of the machine by its own weight,
There is a problem that the belt transmission unit is damaged by excessive tension or a driving load on a lower conveyor of the belt becomes excessive. In addition, when the grain tank is rotated horizontally, it is necessary to remove and attach the belt by entering and leaving a hand in a narrow space at the front of the grain tank and behind the driver's seat. There is a defect.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a conveyor drive shaft on the machine side by a one-touch connecting clutch which can be disengaged by the horizontal rotation of a grain tank on the machine on one side of the threshing section. In the combine that connects the input shaft of the grain tank and also provides a lock member that connects the grain tank to the machine, the lock member, the conveyor drive shaft, and the one-touch connection clutch are provided at the front of the grain tank in a side view. The lock member is attached to the rotating end at substantially the same position, and the lock member is attached to the outside of the grain tank in the horizontal rotation from the attachment position of the one-touch connection clutch, and the driving force is transmitted through the one-touch connection clutch. It can eliminate the problems caused by flexible wire transmission or belt transmission, such as belt removal / removal operation in a narrow space between the driver's seat rear side and the grain tank front side, which are close to each other. In addition to making it possible to easily perform the horizontal rotation workability of the grain tank and simplify the handling operation, the bearing member of the conveyor drive shaft is provided on the grain tank sliding guide surface of the machine stand, The one-touch connection clutch for connecting the input shaft and the conveyor drive shaft can be engaged and disengaged by a sliding operation of a grain tank, and engine power can be transmitted from a conveyor drive shaft of a bearing member to a lower conveyor, and Since each shaft and the one-touch connection clutch are disposed at substantially the same position as the lock member in a side view, the connection between the input shaft and the conveyor drive shaft by the one-touch connection clutch can be appropriately maintained by the grain tank fixing operation of the lock member,
It is possible to easily prevent the one-touch coupling clutch from being disengaged by the rotational force of the conveyor drive shaft or generating or damaging abnormal noise due to the eccentricity of the engagement portion. Can be arranged at a position where it can be easily performed.
