A water tank 12 and a booster pump 13 are installed on one side of the tank body 1. The water inlet end of the booster pump 13 is connected to the water tank 12, and the water outlet end thereof is fixedly connected to a connecting bottom pipe 14;

[0027] A spray unit is provided above the connecting bottom pipe 14 and located inside the tank body 1. The spray unit is used to spray water directly on the scraper 9 and the inner wall of the tank body 1 without affecting the rotation of the scraper 9 to clean the inner wall of the tank body 1, so as to improve the cleaning effect. The spray unit includes a shunt pipe 15 located inside the tank body 1, and the top end of the connecting bottom pipe 14 and the bottom end of the shunt pipe 15 are respectively fixedly connected with a first end ring 16 and a second end ring 17, and the second end ring 17 is rotatably connected to the inner side of the connecting bottom pipe 14. The outer wall of the shunt pipe 15 is fixedly connected to a limiting ring 18, and the first end ring 16 is clamped between the limiting ring 18 and the second end ring 17.
