[0024] When in use, the scraper 10 can be installed between the other ends of the mixing rod 9 by fixing bolts. When mixing materials, the horizontal mixing rod 9 and the vertical mixing support rod 13 can be fully mixed, which can improve the mixing effect. During mixing, the mixing rod 9 can drive the scraper 10 to rotate, scraping off the raw materials attached to the inner wall of the mixing box 1, which can reduce waste.

[0025] Both sides of the rotating tube 6 have baffles 15 facing outwards at the middle of the top of the mixing box 1.

The beating disc 21, under pressure, drives the beating shaft 22 to rotate, lifting the raw material and reducing its falling speed for easier subsequent screening. Then, the motor 4 drives the rotating pipe 6 connected to its output end to rotate, causing the rotating pipe 6 to drive the cleaning brush 8 to rotate at a uniform speed on the screen 7, removing the residue adhering to the screen 7. The raw materials are swept to prevent clogging and affecting the filtration effect. Then, larger raw materials are allowed to enter the feed trough 14 of the rotating tube 6 through the inclined downward screen 7, and then enter the rotating tube 6 through the feed trough 14. The larger raw materials can be discharged into the raw material collection box through the discharge pipe 12 and undergo secondary crushing to prevent larger raw materials from mixing with it and affecting the mixing effect. At the same time, during the mixing, the horizontal stirring rod 9 and the vertical stirring support rod 13 can fully stir it, which can improve the mixing effect. During the stirring, the stirring rod 9 can drive the scraper 10 to rotate and scrape off the raw materials attached to the inner wall of the mixing box 1, which can reduce waste. When the rotating tube 6 drives the stirring rod 9 to rotate forward and backward, it can drive the spiral stirring blade 11 to rotate and transport the raw materials upward and downward, so that the mixed raw materials can be discharged into the mixing collection box through the annular discharge trough and the discharge hood 3.
