The hopper is mainly used in various production equipment that require a large amount of feed. The most commonly used hopper structures are cylindrical hoppers with spiral grooves and conical hoppers. Due to the lack of stirring and fine screening in existing hoppers, the existing hoppers are unable to screen the materials transported into the hopper;

[0003] Common hoppers on the market cannot screen the materials transported into the hoppers. In order to solve this problem, a hopper for transporting dry powder particles is now provided. Utility Model Content

[0020] In summary, the beneficial effects of the utility model are:

[0021] 1. By connecting the driving motor to the power supply, multiple brush scrapers start working, and the dry powder particles to be transported and finely screened are poured into the cavity of the hopper shell. After being poured, the dry powder particles are finely screened through the screen and enter the lower part of the hopper shell. The large dry powder particles that have not passed through the screen remain on the upper part of the screen waiting for further processing. The large dry powder particles are pushed by the friction of the brush scraper to break them into smaller particles to pass through the screen. After passing through the screen, the small dry powder particles slide down through the discharge port to complete the transportation of the dry powder particles. This process ensures that the dry powder particles can be transported in the state of small particles during transportation. At the same time, multiple brush scrapers are independent detachable parts, which are convenient for later maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS
