Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conventional combine for cutting and threshing grains such as rice, wheat and soybeans.

[0002]

Conventionally, a drive shaft at the rear of the feeder house is provided in front of the threshing unit, a crop harvesting header is provided in front of the feeder house to form a mowing unit, and the mowing unit is movable up and down in front of the threshing unit. There is a technology that continuously harvests the culm harvested by the grain harvesting header from the feeder house and feeds it to the threshing unit. It is necessary to stop the work, stop the engine and take out the clogged culm from the cereal header or feeder house, which makes it difficult to simplify the handling operation and improve the efficiency of the harvesting operation. There is.
