Description

They usually include tunnels, shafts, and mining faces, etc. During the mining of coal mines, a large amount of dust will be generated, which not only affects the vision but also can be inhaled into the body and cause harm. Therefore, a dust reduction device is needed to remove dust from the mining environment.

[0003] A Chinese patent with patent number CN215332968U discloses a dust removal and dust reduction spray device for coal mining. The bearing is driven to rotate by a motor, and the connecting pipe on the bearing linkage sleeve changes its angle. The nozzles are evenly distributed above the connecting pipe, which increases the spray area and ensures the uniformity of the spraying, thereby improving the dust reduction effect and being able to reduce dust in different spray areas.

The staff will need to move and adjust it, affecting the progress of the spraying. Utility Model Content
