The rotating shaft 8 is rotatably connected with the rotating shaft 9. The rotating shaft 9 is arranged inside the rotating shaft 8 so that the rotating shaft 8 and the rotating shaft 9 can rotate in opposite directions relative to each other. The rotating shaft 8 and the rotating shaft 9 are respectively rotatably connected with the mounting frame 3. The mounting frame 3 is used to provide support for the first gear 5, the second gear 6 and the third gear 7 so that they rotate on the mounting frame 3. The relative movement of the rotating shaft 9 and the rotating shaft 8 is realized through the power of the driving motor 4 and the meshing transmission of the first gear 5, the second gear 6 and the third gear 7.

[0024] The rotating shaft 8 is fixedly connected with a wall scraper assembly 10, which cleans the raw materials adhering to the inner wall of the mixing barrel 1 during the mixing process. It helps to improve the mixing efficiency and ensure that the raw materials are fully mixed and processed.

The raw material flows to the second inclined plate and passes through the discharge port. The dried raw material leaves the drying box 131 and enters the feed assembly 12. The second pulley 122 of the feed assembly 12 rotates and drives the second pulley 126 to rotate through the belt 127 , so that the rotating drum 124 fixedly connected to the second pulley 126 rotates synchronously. Since the bottom of the rotating drum 124 is fixedly connected with a curved pipe 125, the curved pipe 125 can rotate the drum 124 in the mixing barrel 1, so that the raw materials are evenly dispersed in the mixing barrel 1, and then the driving motor 4 is turned on. Through the power of the driving motor 4, through the meshing transmission of the first gear 5, the second gear 6 and the third gear 7, the relative movement of the rotating shaft 9 and the rotating shaft 8 is realized. The relative movement of the rotating shaft 9 and the rotating shaft 8 can drive the scraping assembly 10 and the stirring rod 11 to move relative to each other, so that the raw materials are fully mixed, ensuring the quality and uniformity of the final product.
