[0025] The lower end of the feeding pipe 8 is fixedly connected to a material spraying plate 9, and a plurality of spray holes 5 are provided on the inner bottom wall of the material spraying plate 9. When the material hole 10 containing powder is connected to the air pump 6, the airflow sprayed by the air pump 6 drives the powder in the material hole 10 to enter the material spraying plate 9 through the feeding pipe 8. The bottom surface of the material spraying plate 9 is fixedly connected to a stirring rod 13, and the shape of the stirring rod 13 is a circular curved structure. The plurality of spray holes 5 are gradually inclined outward from the inside to the outside, and the airflow drives the spray material located in the material spraying plate 9 to be sprayed from the spray holes 5. Since the plurality of spray holes 5 are gradually inclined outward from the inside to the outside, the powder in the material spraying plate 9 is sprayed out from the spray holes 5. The mixing outer cylinder 1 is gradually inclined outward so that the sprayed powder is evenly sprinkled on the upper surface of the mixture in a diffused state, and then mixed when the stirring rod 13 rotates, so that the powder is evenly mixed in the mixture. The upper surface of the mixing outer cylinder 1 is installed with a power structure 4, and the rotating ring 3 and the material passing pipe 8 are both connected to the power structure 4. The inside of the mixing outer cylinder 1 is fixedly installed with a spray rack 11 connected to the outside, and the outer end of the spray rack 11 is connected to the water supply structure.

The powder in the spraying disk 9 is sprayed out from the spray hole 5 driven by the air flow and evenly sprinkled on the mixed material below. The lower gear 403 drives the feed pipe 8 to rotate by meshing with the driven gear 404. The feed pipe 8 drives the stirring rod 13 to rotate through the spraying disk 9 to stir the mixed material.
