PROBLEM TO BE SOLVED: To provide a discharging device for combine harvester that is especially designed so that the damage of grains may be suppressed and also so that unloading efficiency may be increased while the grain-unloading operation. SOLUTION: A grain-unloading device 11 for conveying the grain inside the grain tank 3 in the crosswise direction and unloading is provided on the bottom part of the grain tank 3. Then, a grain elevator 12 for elevating the unloaded grain is connected to the grain-unloading device 11. A grain-discharging auger 13 is attached to the upper part of the grain elevator 12 for unloading so that the front end unloading opening on the top edge may rise and fall or may rotate. A hopper 15 is detachably attached to the side part of the grain tank 3. A cylindrical material 21 for pneumatically unloading the grain in the hopper 15 on the lower part of the hopper. The unloading device for the combine harvester equipped with an auxiliary opening part 35 having an opening and closing door 36 is provided on the side plate 18 of the hopper 15.
