Device for automatically and quantitatively filling dry materials

The invention relates to a device for automatically and quantitatively filling dry materials, which comprises a material containing mechanism for containing the dry materials, a material conveying mechanism for conveying the dry materials, and a material conveying mechanism for conveying the dry materials, a first discharge hole is formed in the lower end of the conveying pipe; the material conveying pipe is located over the material containing mechanism. The material scraping plate is arranged under the material containing mechanism; the scraping plate is provided with an opening matched with the dry material outlet; the material pushing plate is arranged on the bottom surface of the material scraping plate through a supporting frame; a plurality of first through holes are formed in the material pushing plate at equal intervals; and the driving mechanism is used for pushing and pulling the material pushing plate to make the material pushing plate reciprocate in the supporting frame. The quantitative dry mate
