[0025] Working principle: When in use, the device is driven by a tractor. When the driving motor 102 is turned on to drive the cleaning disc 101 to rotate and clean the road surface, the extraction pump 4 can be turned on. The extraction pump 4 sequentially sucks the dust around the cleaning disc 101 through the installation groove 1 and multiple suction pipes 2. Under the suction force, the gas containing dust enters the installation groove 1 through multiple suction pipes 2, and the gas passes through the L-shaped filter 3 and sequentially passes through the cone cover 5 and the connecting pipe 6 into the water tank 7. The L-shaped filter 3 blocks the dust impurities in the gas on the right side, and the water tank 7 adsorbs the tiny particles in the gas. After the gas is adsorbed, it floats up under the action of buoyancy and is discharged to the outside through the exhaust pipe 9. By filtering and purifying the extracted dust gas, the dust can be effectively processed, and the dust reduction is carried out by suction at the bottom, which can effectively reduce the situation where dust adheres to the ground and affects cleaning.

[0026] The inclination angles of the multiple water spray pipe heads 14 are adjusted in advance according to the required spraying angle. When adjusting, the two T-shaped compression bolts 16 are rotated in the opposite direction. The T-shaped compression bolts 16 are separated from the corresponding connecting shafts while being rotated, and the fixation of the connecting shaft and the cross pipe 13 is released. At this time, the cross pipe 13 can be rotated, and the cross pipe 13 drives the multiple water spray pipe heads 14 to rotate. When the required angle is adjusted according to the spraying needs, the rotation of the cross pipe 13 is stopped, and the T-shaped compression bolts 16 are rotated forward. The T-shaped compression bolts 16 are rotated and move downward to be in close contact with the top of the corresponding connecting shaft. Under the action of the friction force between the connecting shafts, the connecting shaft is fixed, thereby fixing the cross pipe 13 and the multiple water spray pipe heads 14. After cleaning a short distance, the water pump 10 is turned on. The water pump 10 extracts water from the water tank 7 through the L-shaped extraction pipe 11 and the water suction head. The extracted water is discharged into the cross pipe 13 through the hose 12 and the connecting pipe in turn. The water in the cross pipe 13 is discharged through the multiple water spray pipe heads 14 to spray the cleaned ground. By spraying and dust reduction after cleaning, the cleaning operation will not be affected. At the same time, the dust reduction effect can be effectively achieved by combining the method of suction and dust reduction during cleaning.

[0027] When the L-shaped filter 3 needs to be removed for cleaning later, the U-shaped handle can be pulled upward to drive the counterweight cover 8 to move upward, and the counterweight cover 8 drives the L-shaped filter 3 to be removed from the installation slot 1, and the L-shaped filter 3 can be cleaned. After cleaning, the L-shaped filter 3 can be moved back into the installation slot 1 and wait for the next use.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
