[0034] The following provides specific usage of the device: 1. In the building foundation construction area of ​​the newly built residential area, the ground is relatively flat. The dust suppression device is moved to the edge of the site, the power is turned on, the pump body 8 is started through the control system 21, the drive motor 38 is started, and the control device slowly moves along the boundary of the site at a speed of 0.1 m / s. The crawler 13 rotates smoothly, and the elastic parts of the front wheel group 15 and the supporting wheel group 19 are slightly extended and retracted to adapt to the slight undulations of the ground; the water in the dust removal box 5 is extracted through the pump body 8 and sprayed out through the nozzle to form a fine water mist to cover the construction area, and the dust in the air settles rapidly.

Even under complex road conditions, the equipment runs stably, without tipping or jamming, and effectively suppresses the spread of dust.

[0036] 3. When dust reduction operations are carried out over a long period of time and over a large area, the second valve 25 of the return pipe 6 is opened to adjust the drainage volume. After a period of operation, the dust removal box 5 is checked. The bottom inclined surface allows the accumulated water to flow smoothly to the outlet pipe 6.

The pressure gauge 23 monitors the water pressure of the drainage pipe 9 in real time and adjusts the power of the pump body 8 in a timely manner. According to calculations, compared with the water-saving mode not being enabled, the water resource recovery rate has been greatly improved, and the nozzle blockage rate has been reduced, which greatly saves water resources and equipment maintenance costs while ensuring the dust reduction effect.

[0037] The dust suppression device for construction provided by the present invention optimizes and innovates from multiple dimensions such as dust suppression effect, maneuverability, stability and water saving, effectively solves the problem of dust in construction, and has broad market application prospects.
