Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a combine harvester mounted on a clentan tanker body for storing grains processed in the threshing unit and taken out from the threshing unit.

As mentioned above, in a combine in which a grain tank is mounted on the fuselage, the grain tank is usually arranged to the side of the threshing section mounted on the fuselage of the combine so as to be parallel to the threshing section. It is fixedly mounted on the machine body, and a transmission mechanism for driving each operating part of the machine body of the threshing unit and a grain transfer device of the grain tank are installed on the side of the threshing unit adjacent to the grain tank. Since a driving transmission mechanism is provided, the grain tank covers the transmission mechanism, making it difficult to inspect and adjust the transmission mechanism.
However, there is a problem that reduces the efficiency of inspection and maintenance.

To do this, the grain tank could be removably mounted on the fuselage of the combine, and removed during maintenance, but the grain tank is quite large. , a lift is required for removal, and prior to its removal, a transmission mechanism that is transmitted from the threshing section side to drive a grain transfer device such as a grain lifting machine that the grain tank is equipped with. The problem arises that the operation is cumbersome because it requires a separate tool to remove it.

The purpose of the present invention is to solve these problems and propose a new means to prevent the grain tank installed on the combine harvester from becoming a hindrance to maintenance. The connection of the seventh grain tank threshing section to the first grain lifting machine, which is suspended, and the connection between the input shaft of the grain transfer device of the grain tank and the power take-off shaft provided on the side of the body of the threshing section are made by inserting and removing. It is not mechanically difficult to ensure that the tank can be loaded and unloaded, and that the direction of insertion and removal for loading and unloading is in the left and right direction of the combine machine. By mounting the grain tank so that it can move left and right and moving it away from the threshing section, a large space for maintenance can be created on the side of the grain tank side of the threshing section. Therefore, the grain tank is mounted on the machine body in parallel to the side of the threshing section, and the grain tank is mounted so that it can move forward and backward with respect to the threshing section along the left and right direction of the machine body, and the grain tank is not separated from the threshing section. The feature is that a support stand is provided on the fuselage without supporting it.
