[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. The vast majority of coal mines in my country are underground coal mines. The scope of a coal mine includes a large area above ground, underground and related facilities. A coal mine is a reasonable space excavated by humans when digging geological strata rich in coal, usually including tunnels, shafts, mining faces, etc.

[0003] In the process of coal mining, the mined coal will be transported out of the coal mine through a conveyor belt. In the process of conveying the coal mine by the conveyor belt, in order to avoid dust, a dust suppression device will be used to spray during transportation. Although such an operation can achieve a certain dust suppression effect, it still has the following shortcomings in actual use;

[0004] Coal mine areas are often accompanied by a large amount of dust. When the dust suppression device is not in use, these impurity dusts can easily clog the spray head, thus affecting subsequent use. Utility Model Content
