Glass powder screw feeder

The invention discloses a glass powder spiral batch feeder, and relates to the technical field of transportation devices, the glass powder spiral batch feeder comprises a feeding bin and a crushing assembly, a screening assembly is arranged on one side in the feeding bin, the crushing assembly is arranged on the other side of the feeding bin, and the crushing assembly comprises a shaft rod, a transmission wheel, a compression roller, fine holes, a collection cavity, an air delivery pipe, a heater and a fan; shaft rods are symmetrically and rotationally connected to the other side of the feeding bin, and one end of each shaft rod is connected with a transmission wheel. During use, materials in the feeding bin can be stirred, and the feeding bin is driven to shake during stirring, so that the materials are vibrated, bridging of the materials in the feeding bin is avoided, during feeding, the materials can be screened through shaking of the feeding bin, large-particle materials are crushed, and the materials are
