The liquid supply system is arranged, when the liquid supply system works, the water pump is started, liquid in the water storage tank is conveyed to the spray head 5 through the water conveying pipe, the spray head 5 atomizes and sprays the liquid into the fog gun barrel 4, and atomized liquid drops are formed and sprayed out through high-speed airflow in the fog gun barrel 4.

Referring to fig. 1 to 4, the working principle of the spray dust settling device is as follows:

starting a liquid supply system, enabling liquid to reach the spray head 5 through a conveying pipeline, and forming liquid drops through the spraying action of the spray head 5; starting the fog gun barrel 4, forming high-speed airflow in the fog gun barrel 4, and crushing the liquid drops into fine liquid drops by the high-speed airflow so that the liquid drops are further atomized and sprayed out from an outlet of the fog gun barrel 4; because the adjusting sleeve is arranged at the outlet of the fog gun barrel 4 and encloses the outlet of the fog gun barrel 4, atomized liquid from the fog gun barrel 4 drops into the adjusting sleeve; the spray adjustment module 6 starts adjusting the spray range: firstly, adjusting the action of a driving mechanism, driving an adjusting sleeve to open a small angle, wherein at the moment, the spray from the adjusting sleeve is outwards dispersed and sprayed out at a small angle, and the spraying stroke is large when the dispersion angle is small, so that the best spraying effect is formed at the position of a far end; then, the adjusting driving mechanism continues to act to drive the adjusting sleeve to open a medium angle, at the moment, the spray from the adjusting sleeve is outwards diffused and sprayed at a medium angle, the diffusion angle is medium, the spray stroke is medium, and the best spray effect is formed at the position with the medium stroke distance; then, the adjusting driving mechanism continues to act to drive the adjusting sleeve to open a large angle, the spray from the adjusting sleeve is sprayed out in a diverging mode at the large angle, the spraying stroke is small if the diverging angle is large, and the best spraying effect is formed at the position of the near end; the atomized liquid drops from the adjusting driving sleeve can be controlled to have the maximum spraying effect in the range of the whole spraying stroke through the continuous driving action of the adjusting driving mechanism, so that the spraying dust-settling effect in a larger coverage range is realized; in addition, the spraying direction of the spraying assembly 2 is adjusted through the adjusting device 3, for example, when the spraying assembly 2 is adjusted to rotate around a vertical axis, spraying within a range of 360 degrees can be realized, and the coverage range of spraying dust fall is further enlarged.

The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
