[0020] The working principle of this utility model is:

[0021] When using the device, the rear end of the roller assembly 5 can be connected to the tractor, or the dust cover 2 can be connected to the support arm of the existing roller, so that the existing roller roller can be set behind the dust cover 2; the device is connected to an external power supply, and is powered by the tractor or the roller. When in use, water is injected into the water tank 3-1 through the water inlet 3-2, and the air outlet end of the suction pump 4-4 is immersed in the water. The water pump 3-4 is powered on to pump out the water in the water tank 3-1, and the water is injected into the water distribution tank 3-5, and then sprayed out by the atomizing nozzle 3-6, which can humidify the surface of the roadbed aggregate and reduce the dust generated by the collision between the aggregates when the roller is working. The suction pump 4-4 is powered on to suck out the air in the collection box 4-2. Negative pressure is generated in the cavity 2-1 through the air intake pipe, so that the outside air can be sucked into the cavity 2-1 through the multiple dust cover holes 2-2. The entry of air can make the raised dust enter the cavity 2-1, and then enter the collection box 4-2 through the cavity 2-1 and the air intake pipe to collect the dust. The filter 4-3 plays a role in filtering dust. The above method can further reduce the dust raised by the roller during operation. The air extracted by the vacuum pump 4-4 is discharged into the water in the water tank 3-1 through the air outlet end, which can further reduce the fine dust brought out by the vacuum pump 4-4 when extracting air. The gas is discharged through the air outlet 3-3, and the net bucket 4-5 can collect the dust in the gas discharged by the vacuum pump 4-4.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
