When the through slot 2111 is connected to the feed pipeline 1, the rotating ring 2113 is driven to rotate by the second motor 2117, and then the rotating ring 2113 is obliquely arranged on the inner wall of the rotating ring 2113. A plurality of fan blades 2114 increase the air flow velocity inside the feed pipe 1, improve the thrust on the material at the blocked position, and facilitate clearing the blocked position. The second motor 2117 is fixedly installed inside the movable block 207. The top and bottom ends of the movable block 207 are fixedly installed with limit arc plates 208. When the lower limit arc plate 208 contacts the bottom wall of the feed pipe 1, the feed trough 209 is connected to the feed pipe 1.
