The roller brush 54 sweeps the dust and debris into the inlet of the ash collection box 57. The ash collection box 57 sucks in the dust and debris through the vacuum pump 55, thereby reducing the dust content in the working environment and fundamentally alleviating the problem of high dust.

Thus, when the piston 45 advances in the pump barrel 461, the upper one-way check valve member 463 closes and the lower one-way check valve member 463 opens, thereby pumping water from the water tank 465. When the piston 45 retracts in the pump barrel 461, the lower one-way check valve member 463 closes and the upper one-way check valve member 463 opens, thereby transporting the water to the second branch pipe 464, and the water flows from the second branch pipe 464 to the water delivery pipe 466 and from the water delivery pipe 466 to the two spray pipes 467, thereby generating spray for atomized dust removal, with relatively low energy consumption and high automation;

The first large gear 61 drives the first small gear 63 to rotate. The first small gear 63 drives the second small gear 65 to rotate. The second small gear 65 drives the second large gear 66 to rotate, thereby realizing the linkage of the two groups of cleaning disk brushes 53 in opposite directions, facilitating the cleaning of the ground and the collection of dust and debris. The dust and debris are cleaned and transferred to the roller brush 54. The roller brush 54 sweeps the dust and debris into the inlet of the dust collection box 57. The dust collection box 57 sucks in the dust and debris through the vacuum pump 55, thereby reducing the dust content in the working environment and fundamentally alleviating the problem of high dust. The cleaning component 5 is provided with a vacuum pump 55, which can intake air quickly, improve the rate of dust treatment, thereby reducing the dust concentration in the working environment, effectively carrying out targeted dust reduction in a local area, and improving the air quality of the working environment;

[0055] While spraying and dust suppressing, this device also drives the cleaning component to remove the surface dust of the passing road surface, thereby maximizing dust suppression. It is convenient to operate and flexible to deploy.
