Quantitative screw conveying device for raw materials

The utility model discloses a quantitative screw conveying device for raw materials. The quantitative screw conveying device comprises a conveying device body, a conveying rod, a conveying groove, a quantitative structure, a fixing seat, a feeding hopper, a rotating shaft, a receiving plate, a through hole and a driving structure. The material receiving device has the advantages that the driving structure is used for driving the rotating shaft to rotate, the rotating shaft rotates to drive the material receiving plates on the side face of the rotating shaft to rotate, and therefore when the two adjacent material receiving plates rotate to the topmost portion and are matched with the tops of the through holes, raw materials in the feeding hopper can fall into the two adjacent material receiving plates and the rotating shaft, and the raw materials are conveyed to the feeding hopper. After the two material receiving plates containing the raw materials rotate, the raw materials located between the two adjacent ma
