The elastic hammer 26 of the vibration mechanism generates vibration between the outer cylinder 10 and the delivery pipe 9, which enhances the looseness of the waste during transportation and prevents material accumulation and blockage. Driven by the air flow of the air supply pipe 12, the vibration mechanism is linked with the delivery pipe 9 to continuously loosen the blockage points during the material transportation process and improve the transportation efficiency. The drying mechanism heats and dries the waste in the delivery pipe 9 to reduce the humidity and prevent wet waste from adhering to the pipe wall. In conjunction with the vibration mechanism, the dried material is looser, further reducing the possibility of adhesion and blockage.
