The bucket elevator 200 of this embodiment 1 is an improved design based on the prior art. Referring to fig. 2 and 3, the main body of the apparatus includes a vertically disposed feed housing 201, an upper hopper 202 is disposed at a lower end of the feed housing 201, and the upper hopper 202 is disposed at the other side surface connected to the discharge passage 400. An end shield 203 is provided at the upper end of the feeder housing 201. One belt conveying roller 204 is disposed inside the lower end of the feeder housing 201 and in the end cover 203, respectively, and the two belt conveying rollers 204 are on the same vertical line. A conveyor belt 205 is provided between the two belt conveyor rollers 204, a plurality of buckets 206 are connected to the conveyor belt 205 at equal intervals, and the bucket 206 on the side close to the upper hopper 202 is designed to have an opening facing upward and the bucket on the side close to the discharge path 400 is designed to have an opening facing downward. In addition, a lifting motor 207 is arranged on the outer side surface of the end cover 203, and an output shaft of the lifting motor 207 extends into the end cover 203 and is connected with the end surface of the belt conveying roller 204. The conveyor belt 204 is driven by the lifting motor 207 to rotate clockwise in the feeding housing 201, so that the grain can be dug up by the digging hopper 206 on the conveyor belt 205 when entering the bottom end of the discharge passage 400 from the discharge passage 400 or the upper hopper 202 and then conveyed upward along with the conveyor belt 204. When the bucket is turned over as the conveyor belt 204 moves to the top of the end shield 203, the grain in the bucket 206 can be thrown down.

Referring to fig. 3, a discharging opening 2031 is formed at a lower end of the end shield 203 near the grain dryer 100, wherein a top end of the discharging pipe 300 is connected to the discharging opening 2031, so that the grain can be thrown down when the grain in the hopper 206 is turned over, and then enter the discharging pipe 300 through the discharging opening 2031. Meanwhile, the side surface of the end cover 203 close to the dryer 100 is provided with a dust suction port, and the outer end of the dust suction port is connected with a dust suction trapezoidal cover 500.
