BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine equipped with a grain tank for collecting sorted threshed grains.

[0002]

SUMMARY OF THE INVENTION Conventionally, Japanese Utility Model Application Laid-Open No. 59-3
As disclosed in Japanese Patent No. 4543 or Japanese Utility Model Application Laid-Open No. Sho 59-31841, there is a technology in which an engine is installed below a driver's seat and a grain tank is mounted on a machine upper surface behind the engine so as to be rotatable laterally. However, when the driven body is fixed to the front end of the auger shaft of the transverse feed auger at the bottom of the tank, and the driving body connected to the driven body is fixed to the driving shaft, by connecting the driven body and the driving body with a V belt, It is necessary to perform a V-belt attaching / detaching operation simultaneously with the lateral turning operation of the tank,
The handling operation cannot be simplified or the like, and the driven body and the driving body are always connected by a flexible transmission wire, so that the V-belt attaching / detaching operation can be omitted, but the turning angle of the tank is increased. Therefore, there is a problem that the wire becomes long, and the storing of the wire becomes troublesome, and there is a problem that the wire is extended to the tank opening portion, and a worker is hooked on the wire to restrict the movement. . Then, the actual opening 62-134350
As shown in the publication, there is also a technique of connecting the auger shaft of the tank lateral feed auger to the drive shaft of the machine via a driving body and a driven body, but a shaft crossing the auger shaft is provided and the driven body is attached. The auger shaft input structure cannot be easily simplified and lightened, and the auger shaft alone cannot be easily driven by branching the driving force of the threshing unit and transmitting the engine power to the drive shaft. There is a problem.

[0003]

According to the present invention, an engine is provided below a driver's seat, and a grain tank is mounted on a top surface of a machine rear of the engine so as to be rotatable laterally. In the combine for fixing the driven body to the front end of the auger shaft of the lateral feed auger and for fixing the driving body to be engaged with the driven body to the driving shaft, the driven body and the driving body are engaged around the driving shaft and integrally rotated. And a lock member for maintaining the driven body engaged with the driven body is attached to the guide body while the driven body is removably connected to the driven body in the lateral rotation direction of the tank. Since the drive shaft is connected to the auger shaft of the tank through the driven body and the driven body that is disengaged by the lateral rotation operation of the tank, the driven body can be detached from the drive body only by the lateral rotation operation of the tank. Engage driven body with driven body The operation of removing the conventional V-belt can be eliminated, eliminating problems such as belt slip or mis-belt, and eliminating the need for the connection of the conventional flexible transmission wire. In addition to eliminating restrictions on work, the operability can be improved, the drive structure can be simplified, the auger shaft input section can be lightened, and the driven body can be easily engaged or disengaged from the drive body. Since the lock member is attached to the guide body that guides the movement, the lock member can support the driven body opposite to the drive body in an appropriate posture, prevent uneven wear of the driven body and the drive body, improve durability, and reduce drive noise. This can be easily achieved.
