Abstract

PROBLEM TO BE SOLVED: To widen the mounting range of a grain carrier at the time of grain filling work by shifting the center in the back and forth direction of a hopper inward from that of a grain elevator on the outer face at the lower part thereof and separating one end part of time shoot outward by a specified distance from the elevator. SOLUTION: Grains harvested by combine, or the like, is transported by a truck and thrown into a hopper 31 mounted on the outer face at the lower part of the grain elevator 26 of a dryer with one end 32 thereof being spaced apart therefrom by a specified distance. The grains are elevated and carried into a grain storage room 7 by rotary driving a belt 28 with bucket conveyor 27 in the elevator 26. Since the center in the back and force direction of the hopper 31 is shifted inward from that of the elevator and one end 32 of the hopper 31 being spaced apart from the dryer be a specified distance, a grain carrier for throwing grains into the hopper 31 does not collide against the dryer thus enhancing the workability of grain filling work.
