PROBLEM TO BE SOLVED: To provide a lift, capable of stably throwing out grain by means of a bucket. SOLUTION: In this lift 10, a belt 36 for a bucket conveyor 20 is held straight at a part between an upper flat pulley 32 and a subsidiary pulley 34 in the opening direction to a throwing port 21. Grain in the bucket 38 thus starts being thrown at a position that is similar to that in conventional lifts (position S). However, as the bucket 38 rotates around the upper flat pulley 32 to get into the straight part, speed of the tip of the bucket 38 slows down, and therefore the grain in the bucket 38 is mostly thrown out in the straight part in the moving direction of the bucket 38 (in the opening direction of the throwing port 21). The grain in the bucket 38 can thus be thrown out almost completely at position A, thereby the grain can be stably thrown out. COPYRIGHT: (C)2007,JPO&INPIT
