PROBLEM TO BE SOLVED: To solve a problem that wet grains have bad grain fluidity, do not smoothly flow in a carrying conveyer to lower the discharge speed of the grains, and adhere to the inner wall surface of a grain tank to highly increase left grains, while the carrying conveyer is disposed in the inner lower portion of the grain tank of a combine harvester having the grain tank loaded thereon, and operated to forcibly discharge the grains at a high speed in improved discharge efficiency, and to solve a problem that the volume of the grain tank is reduced, although it can be considered to form the bottom of the grain tank in steep slopes to prevent the left grains. SOLUTION: This combine harvester in which the carrying conveyer 37 is disposed in the inner lower portion of the grain tank 29 is characterized by disposing eccentric shafts 40, 56 at places near to the carrying conveyer 37 and driving a movable plate 82 on a bottom plate 29e through the eccentric shafts 40, 56.
