Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine harvesting device in which a harvesting section slides left and right with respect to a machine having a threshing section.

[0002]

2. Description of the Related Art Conventionally, a reaping part is slidably supported at a tip of a reaping connecting pipe extending forward of a machine body, and the reaping part is laterally fed by screw feeding by a cylinder or a motor.

[0003]

Since an actuator such as a cylinder or a motor for sliding the reaper is inevitably arranged at the lower part of the reaper, it has been damaged due to contact with a field scene or adhesion of mud.

An object of the present invention is to provide a combine harvester that isolates an actuator for sliding a harvester from a field scene to prevent damage to the actuator.

[0005]

SUMMARY OF THE INVENTION Therefore, the combine harvesting device of the present invention is provided with a support case for slidably supporting the harvesting part at the tip of the harvesting connecting pipe extending to the front of the machine body. It is characterized in that a reinforcing member extending in the left-right direction is integrally extended, and an actuator for sliding the cutting unit is arranged inside the reinforcing member.

[0006]

[Operation] Therefore, since the actuator that slides the mowing part is isolated and protected from the field scene by the support case and its reinforcing member, it is possible to prevent the actuator from coming into contact with the field scene and adhesion of mud. Can be prevented from being damaged.
