GRAIN DISCHARGER

[Object] To provide a grain discharger that stabilizes support of the vertical grain-elevating device and smoothly rotates it. [Solution] A grain discharger comprising: a grain tank (5); a discharging helix (32) provided at the bottom of the grain tank (5); a connect member (11) that is L-shaped if seen in side view; a horizontal cylinder unit (15), provided in the connect member (11), for incorporating the terminal end of the discharging helix (32); a helical grain elevator (34); a grain-elevating cylinder (20) for incorporating the helical grain elevator (34); a vertical cylinder unit (30), provided in the connect member (11), into which the bottom of the grain-elevating cylinder (20) is inserted in such a way that it is rotatable about the vertical axis; wherein the grain-elevating cylinder (20) includes an upper cylinder (47) to which a horizontal discharge cylinder (13) is connected at its upper end, and a lower cylinder (48) that is thicker than the upper cylinder (47); and the bottom of the lower cylinder (48) is inserted into the vertical cylinder unit (30) in such a way that it is rotatable about the vertical axis.
