PROBLEM TO BE SOLVED: To eliminate a problem that soft skin grains, especially soybeans, among harvested grains are damaged to lower their commercial value, although a long vertical spiral disposed in a pipe and a grain-discharging spiral capable of being revolved in the vertical and lateral directions are generally used as means for discharging the harvested grains from a tank receiving the grains. SOLUTION: In this grain-discharging device, grains discharged from a tank discharge port 2 disposed at the lower end of a tank 1 are discharged from a grain discharge port 5 formed at the end of a grain guide pipe 4 with the wind force of a fan 3, and at least a prescribed portion ranging from a place near to the tank discharge port 2 to the fan 3 in an air duct 6 ranging from the fan 3 to the tank discharge port 2 is downward inclined toward the side of a grain discharge port 5. A forcibly carrying device 7 for forcibly carrying the grains to the tank discharge port 2 is further disposed in the tank 1.
