[0036] Specifically, please refer to Figure 5 , the side surface of the scraping plate 7 is attached to the inner wall of the stirring tank 3.

[0037] In this embodiment, it is ensured that the scraping plate 7 can scrape off the raw materials attached to the stirring tank 3, ensuring the quality of stirring and facilitating the cleaning of the inner cavity of the stirring tank 3.

[0038] Specifically, please refer to Figure 6 , the directions of the three groups of spray holes 23 are respectively inclined upward, horizontally inward, and inclined downward.

[0039] In this embodiment, it is ensured that the spray holes 23 can spray and clean the rotating shaft 5, the stirring rod 6 and the scraping plate 7 from three different directions to ensure the cleaning quality. In addition, the spray holes 23 inclined downward can spray the cleaning water into the stirring tank 3 to clean the inside of the stirring tank 3.

[0040] Working principle: When in use, first use the air cylinder 10 to drive the box cover 4 to move upward, pour the pet feed into the stirring tank 3, and then move the box cover 4 downward until the box cover 4 completely covers the top of the stirring tank 3. At this time, start the vacuum pump 11, use the vacuum pump 11 to extract the air in the stirring tank 3, so that the inside of the stirring tank 3 is in a vacuum state. Then start the servo motor 9 to drive the rotating shaft 5 to rotate, and use the rotation of the rotating shaft 5 to drive the stirring rod 6 and the scraping plate 7 to rotate inside the stirring tank 3 to stir the feed. At the same time, the scraping plate 7 scrapes the feed adhering to the inner wall of the stirring tank 3 during stirring to ensure that the feed is completely mixed. After stirring, start the solenoid valve 13 to discharge the feed in the stirring tank 3 through the discharge port 12, catch the stirred feed through the receiving hopper, and then drive the box cover 4 to lift upward by the air cylinder 10, close the transparent plate 26 and start the water pump 20. The water pump 20 transports the water in the water storage tank 18 to the circular spray pipe 22 through the water guiding hose 21 and the water guiding steel pipe 28, so that the water in the circular spray pipe 22 sprays out from the three groups of spray holes 23. At the same time, start the electric telescopic rod 17 to drive the slider 16, the water guiding steel pipe 28 and the circular spray pipe 22 to move up and down reciprocally. When the circular spray pipe 22 moves to the side of the rotating shaft 5, the stirring rod 6 and the scraping plate 7, the water sprayed out from the three directions of the spray holes 23 sprays and cleans the rotating shaft 5, the stirring rod 6 and the scraping plate 7. In addition, when the spray holes 23 move above the stirring tank 3, the spray holes 23 inclined downward can spray the cleaning water into the stirring tank 3 to clean the inside of the stirring tank 3. The cleaning sewage passes through the grille 2 and drops into the water receiving tray 25. Finally, take out the water receiving tray 25 from the outer box 1 to treat the cleaning waste water, and that's it.

[0041] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present utility model.
