[0043] The pushing assembly 300 includes a limiting ring block 310, which is sleeved on the lower end of the rotating shaft 400. The outer wall of the limiting ring block 310 is fixedly installed with multiple inclined plates 311 for pushing the raw materials upward. One end of the inclined plate 311 is fitted with the bottom of the tank body 100 so that when the rotating shaft 400 drives the pushing assembly 300 to rotate, the inclined plate 311 pushes the raw materials on the bottom wall of the tank body 100, so that the raw materials move upward under the guidance of the inclined plate 311, so that the raw materials with heavy density are scooped up by the inclined plate 311, and then fall down through the upper end of the inclined plate 311 to be mixed with the raw materials with light density.
