AI Technical Summary
The existing dust suppression devices have a fixed spray range, resulting in a small dust suppression area for a single device. This necessitates the deployment of multiple devices, leading to a waste of water resources.
A dust suppression device including a moving mechanism and a dust suppression mechanism was designed. The nozzle is movable by driving the screw with a motor to expand the spraying range, and the direction of the water mist is restricted by the limiting frame to reduce the overlapping area.
This has enabled the dust suppression area of a single device to be increased, the number of devices to be deployed to be reduced, costs to be lowered, water waste to be reduced, and ease of use to be improved.
