The water supply tank 34 is connected to the water washing box 35 through a drainage pipe. The water level of the water supply tank 34 is higher than the water level of the water washing box 35, so that the water washing box 35 can be continuously replenished with water; the smoke exhaust port 322 of the smoke exhaust pipe 321 of the explosion-proof diesel engine 32 is arranged at the top of the water washing box 35 to prevent the problem of back suction when the smoke is not exhausted. A drain valve 351 is arranged on the side of the bottom of the water washing box 35. When draining water through the drain valve 351, the ash in the water can also be discharged synchronously. A smoke outlet 352 is arranged on the top of the water washing box 35. The black smoke of the explosion-proof diesel engine 32 passes through the water washing box 35 and then is discharged through the smoke outlet 352, and the ash is washed away.

In addition, the diesel tank 33 is lower than the hydraulic oil tank 39 and the two form an L-shaped step space 332. The water washing tank 35 is arranged in the L-shaped step space 332, so that the hydraulic oil tank 39, the water tank 34, the water washing tank 35 and the diesel tank 33 are compactly arranged behind the rear wheel 13; the exhaust port 322 of the exhaust pipe 321 of the explosion-proof diesel engine 32 is arranged at the top of the water washing tank 35 to prevent the problem of back suction when the smoke is not exhausted. A drain valve 351 is arranged on the side of the bottom of the water washing tank 35. When draining water through the drain valve 351, the ash in the water can also be discharged synchronously. A smoke outlet 352 is arranged on the top of the water washing tank 35 to wash away the ash. In this embodiment, the heavy hydraulic oil tank 39, water tank 34, water washing tank 35 and diesel tank 33 are compactly arranged behind the rear wheel 13, and the explosion-proof diesel engine 32 is arranged above the chassis 1 between the front wheel 12 and the rear wheel 13, so that the front and rear weight of the chassis is relatively balanced, which is beneficial to the stability of the vehicle body on the basis of compact design.
