The concrete conveying vehicle cleaning device comprises a vibrating screen 31, a spiral silt separator 41, a mixing water tank 51 and a feeding belt 61, wherein the vibrating screen 31 is obliquely arranged above the mixing water tank 51, a feeding hole of the spiral silt separator 41 is formed in the mixing water tank 51, the feeding belt 61 is arranged at a discharging hole of the spiral silt separator 41 and a discharging hole of the vibrating screen 31, a mixed solution of concrete excess materials falling off in the cleaning process of the concrete conveying vehicle and water enters the vibrating screen 31, the concrete excess materials with the grain diameter smaller than 5mm in the mixed solution fall into the mixing water tank 51, and the concrete excess materials larger than 5mm are conveyed away by the feeding belt 61 at the discharging hole of the vibrating screen 31.

With reference to fig. 2 to 4, the movable screen 31 is a swinging vibrating screen or an eccentric block vibrating screen, a screen plate 311 is arranged in the vibrating screen 31, and the vibrating screen 31 swings or vibrates to screen the concrete remainder.

In order to realize the screening of the concrete excess, a plurality of screening grooves 312 arranged along the inclined direction of the vibrating screen 31 are arranged on the upper end surface of the screen plate 311, when the screen plate 311 screens the concrete excess, the concrete excess A with the grain diameter larger than 5mm is arranged on the upper end surface of the screen plate 311, and the concrete excess B with the grain diameter smaller than or equal to 5mm falls into the screening grooves 312.

In order to allow the concrete remnants A placed on the upper end surface of the screen plate 311 to be sent out of the mixing water tank 51, the concrete remnants B dropped into the screening grooves 312 are dropped into the mixing water tank 51. When the screen plate 311 is installed in the vibrating screen 31, the upper end surface of the screen plate 311 is higher than the upper end opening surface of the mixing water tank 51, so that concrete excess materials with the grain diameter larger than 5mm on the upper end surface of the screen plate 311 are discharged out of the mixing water tank 51 and are conveyed away through the feeding belt 61 outside the mixing water tank 51. The bottom surface of the sieving tank 312 is lower than the upper port surface of the mixing water tank 51 so that the concrete remnants falling into the sieving tank 312 are discharged into the mixing water tank 51.
