During the rotation of the annular transmission member 621, it can drive the pusher 61 between the predetermined area 42 and the edge area 43. The goods are pushed from the edge area 43 to the predetermined area 42, and the goods are unloaded in the predetermined area 42. The present invention realizes a The closed-loop movement can drive the movement of the pusher 61 in both directions, thereby realizing the reciprocating motion of the pusher 61 between the edge area 43 and the predetermined area 42. This structure is simple and can ensure the push of goods. The non-stop continuous movement of the object 61 improves the unloading efficiency of the pushed object 61. Optionally, the endless transmission member 621 can be a conveyor belt or a transmission chain. When the endless transmission member 621 is a conveyor belt, the first transmission wheel 628 and the second transmission wheel 629 should be pulleys; When the annular transmission member 621 is a transmission chain, the first transmission wheel 628 and the second transmission wheel 629 should be sprockets.
