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. 60-81750, a grain tank is opened to the outside of a machine body around a vertical axis or housed inside a machine body, and a grain tank is fixed at a housed position. There was a technology for attaching a lock member.

[0003]

In the prior art, the belt is stretched at the front end of the lower conveyor at the bottom of the grain tank, and the driving force is transmitted from the machine side, so that the fixing of the lock member is incomplete. However, 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 an abnormality in the lock member at an early stage, so that the machine is mounted on the tank side with the grain remaining in the grain tank. If it is tilted, the grain tank moves in the outer direction of the machine by its own weight, and the belt transmission unit may be damaged by excessive tension, or the driving load on the lower conveyor of the belt may be excessive. In addition, connecting the rear portion of the grain tank to the vertical axis has a disadvantage that the front portion of the grain tank is lowered by the weight of the grain and the lock member or the mounting portion of the member is easily deformed and damaged.

[0004]

According to the present invention, a rear portion of a grain tank is horizontally rotatably mounted on a vertical axis which stands on a machine stand, and a grain tank in a storage position is connected to the machine side. In a combine provided with a lock member for detachably locking, an input shaft for driving a lower conveyor at the bottom of the grain tank is protruded outside the front of the grain tank, and the input shaft is connected to an output shaft of the machine via a clutch. The shaft is removably connected in the rotation direction of the grain tank, and the lock member is disposed outside the horizontal rotation of the grain tank from the clutch mounting position. In addition, it is possible to prevent accidents caused by erroneous operation or failure of the lock member beforehand, and to provide a lock member on the rotation outside of the clutch so that the worker can operate the lock member at the time of operating the lock member. Easily manipulated resulting in not the transmission part is obstructed, such as a clutch, it is intended to obtain aim and facilitate improvement in simplicity and handling operations of the structure, such as the locking member or the clutch.

In addition, the lower surface of the grain tank at the front end of the lower conveyor is slidably mounted on the machine base. Therefore, it is possible to prevent the front part of the grain tank from lowering due to the weight of the grain, thereby eliminating the problem that the lock member or the mounting part of the member is deformed and damaged, and maintain the input shaft and the output shaft properly and It is possible to easily obtain a clutch which can be easily disengaged by turning the tank.
