Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain tank device for extracting and storing grains that have been threshed and sorted in a threshing section into a grain tank.

[0002]

Normally, the grain tanks are arranged adjacent to each other in parallel on the right side of the threshing section, and when the capacity of the grain tanks is to be increased, a means for expanding the grain tanks in the right outer direction is provided. However, in this case, there is an inconvenience that the entire width of the body is enlarged.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention provides a grain tank device of a combine in which the grains threshed in the threshing section are stored in a grain tank adjacent to the right side through a lifting cylinder. By extending the upper left side above the threshing section, the storage capacity of the grain tank is effectively increased without expanding the overall width of the fuselage.When the grains are stored in the grain tank, the left-right balance is unbalanced. It does not stabilize and keeps good, it is hard to fall over even with a large capacity, and it improves running performance in wetlands.

Further, by providing the above-mentioned fried cylinder on the rear wall of the grain tank, it is possible to satisfactorily expand the grain tank without being affected by the installation of the fried cylinder, and at the same time for maintenance and inspection of the fried cylinder. For convenience, it is possible to easily maintain stable function.
