With the rapid development of China's economic construction, various construction engineering machinery, especially mixers, have been more and more widely used.

The mixer is used to mix various powders such as sand with water to obtain a mortar-like material such as concrete. Please refer to FIG. 1. FIG. 1 is a schematic structural view of a mixer, and a schematic structural view of a typical cleaning device is also shown.

The main body of the mixer shown in the drawing (hereinafter referred to as the stirring main unit 1) includes a rotating body 12 which is located in the stirring cylinder of the stirring main unit 1 and is located below the top cover 11, and the rotating body 12 is under the action of the driving motor 16. The stirring arm 17 that is fixedly connected thereto is rotated. During the agitation of the mortar, a part of the powder or mortar adheres to the inner wall of the agitating cylinder and the surface of the rotating body 12. The above-mentioned adhered mortar or powder will lead to inaccurate metering of the finished mortar; at the same time, the adhered mortar and powder are continuously aggregated on the inner wall of the mixing tank and the surface of the rotating body 12, and the powdered material will fall off. It falls in the stirred mortar, which causes the finished mortar to be uneven and cannot meet the mortar quality requirements of certain construction occasions.

Therefore, timely cleaning of the inner wall of the mixing tank becomes an indispensable task in the operation of the mixer, and the quality of the cleaning device directly affects the cleaning quality and efficiency of the mixing tank.
