[0002] A concrete mixer truck is a special truck used to mix and transport concrete. During the process of transporting concrete, it is inevitable that concrete will adhere to the surface of the truck. Coupled with the fact that the construction site is usually muddy, a large amount of soil will also adhere to the vehicle. If it is not cleaned, when the mixer truck travels on the urban road, it will pollute the urban environment.

[0003] Existing cleaning devices are mostly gantry-type cleaning equipment. The concrete mixer truck slowly travels under the gantry, so that multiple spray heads arranged inside the gantry can wash the mixer truck. However, there is a lot of sewage during the washing process. If the sewage is allowed to flow out, the cleaning site of the concrete mixer truck will be dirty and messy.
