The rack 1 is in the form of a rectangular frame structure, and is hollow at the inside and each end face. The conveying bin 2 is correspondingly arranged above the rack 1, and the outer wall thereof is fixedly connected with the inner walls of the upper and lower edges of the rack 1. The conveying bin 2 is provided with an opening at the top. The dust collecting cylinder 3 is arranged at the opening at the top of the conveying bin 2, and is in the form of a frustoconical structure, and is provided with openings at the top and bottom ends. The opening size at the bottom end is larger than that at the top end. The top end of the dust collecting cylinder 3 is in communication with the negative pressure fan system. The discharge bin 4 is arranged at the lower side of the rack 1. The scraping mechanism is arranged on the rack 1. The conveying mechanism comprises an electric roller 501 and a conveying belt 502. The electric roller 501 is arranged in the conveying bin 2, and is in transmission connection with the conveying belt 502, and is used for conveying the materials 7 into the discharge bin 4. Through the arrangement of the conveying bin 2 and the dust collecting cylinder 3, the dust generated during the conveying of the materials 7 can enter into the conveying bin 2, and be sucked out by the negative pressure fan system through the dust collecting cylinder 3. Meanwhile, the arrangement of the rubber curtain 201 and the rubber plate 202 further prevents the dust from flying out of the conveying bin 2, and reduces the amount of dust flying.

[0031] In some embodiments, the conveying mechanism further comprises a bearing seat 503 and a conveying frame 504. A roller shaft 505 is arranged in the electric roller 501. The bearing seat 503 is symmetrically arranged at the left and right sides of the electric roller 501, and is fixed to the top surface of the upper edge of the rack 1. The roller shaft 505 penetrates through the conveying bin 2, and is limitingly arranged in the bearing seat 503. One end of the conveying bin 2 is provided with an opening. The conveying frame 504 penetrates through the opening of the conveying bin 2, and is fixedly connected with the inner wall of the conveying bin 2. A part of the conveying belt 502 is arranged on the conveying frame 504.

[0032] In some embodiments, the conveying bin 2 is further provided with the rubber curtain 201 and the rubber plate 202. The rubber curtain 201 is arranged on the top wall at the opening of the conveying bin 2. The rubber plate 202 is fixedly arranged on the side wall at the opening of the conveying bin 2, and is correspondingly located below the conveying frame 504.

[0033] In some embodiments, the discharge bin 4 is in the form of a frustoconical structure, and is provided with an opening at the bottom. The top is in communication with the conveying bin 2.

[0034] In some embodiments, the scraping mechanism comprises a stretching assembly 601, a rotating frame 602, a scraping plate 603 and a rotating shaft 604.
