GRAIN TANK OF COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To prevent the loss of lateral balance of the body of a combine harvester to deteriorate the gyrating operability in a combine harvester having a grain tank on one side of the body and increasing the capacity of the tank by expanding a side wall of the tank by preventing the outward expansion of the side wall when the inclination angle of the body exceeds a preset level caused by the increase of the weight of the grain tank. SOLUTION: The side wall of the grain tank is made to be expandable outward to the outside of the body of the combine harvester. The combine harvester is provided with a detection means to detect the amount of unhulled rice grains stored in the grain tank and a detection means to detect the inclination angle of the body. The side wall is expanded to increase the capacity of the tank with a controlling mechanism in connection with the signals transmitted from the detection means exclusively when the amount of the grains in the grain tank reaches a preset level and the inclination angle of the body inclined due to the weight increase of the grain tank is smaller than a preset angle.
