The piston rod 96 can drive the piston plate 97 fixed at its lower end to move up and down reciprocally. When the piston plate 97 moves upward, it can suck in the external water source through the second one-way valve 94. When the piston plate 97 moves downward, it can push out the water source in the first pipe 91 through the first one-way valve 93, and spray it onto the internal gear ring 52 and the gear 54 through the nozzle 95. After flushing the internal gear ring 52 and the gear 54, it flows into the mixing tank 1.

The swing rod 53 can drive the second stirring shaft 3 rotatably connected to its lower surface to revolve around the first stirring shaft 2. The second stirring shaft 3 can drive the gear 54 sleeved on its top end to revolve accordingly. Since the gear 54 and the internal gear ring 52 are meshed with each other, the gear 54 can also rotate on its own when revolving. The gear 54 drives the second stirring shaft 3 to rotate on its own, so that the first stirring shaft 2 and the second stirring shaft 3 stir the materials in the mixing tank 1 in all directions.

[0067] The swing rod 53 can drive the scraper 4 fixed at one end of it to rotate accordingly. Since one side of the scraper 4 is attached to the inner wall of the mixing tank 1, the scraper 4 can scrape off the materials on the inner wall of the mixing tank 1 during rotation.

[0068] The second stirring shaft 3 can drive the eccentric wheel 71 to rotate accordingly. When the eccentric wheel 71 rotates, it can push the screening box 6 to shake left and right along the horizontal direction, screening the materials in the screening box 6;

[0070] The second stirring shaft 3 can drive the cylindrical cam 81 sleeved on its surface to rotate accordingly. Since the limiting rod 83 is slidably connected to the inner wall of the stirring tank 1 in the up and down direction, the movable plate 82 fixed to one end of the limiting rod 83 can only move along the vertical direction.
