The detachable sealing cover 102 can also be removed according to actual use, and the feed pipe 101 is directly connected to the pipeline for transporting materials, which is convenient for the use of the device.

[0026] A further optimized solution is that the first discharging structure includes a first feeding shell 2 connected to the bottom surface of the storage bin 1, the first feeding shell 2 is a hollow cylindrical structure and the axis is horizontally arranged, the first feeding shell 2 is rotatably connected to the axis of the first rotating shaft, and the first rotating shaft is fixedly connected to a plurality of first blades 201 at equal intervals in the circumferential direction, and the ends of the plurality of first blades 201 away from the first rotating shaft are slidably matched with the inner wall of the first feeding shell 2.
