Description

A dust suppression device

Technical Field

The utility model relates to the technical field of coal mines, in particular to a dust suppression device.

Background technique

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. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological strata rich in coal, usually including tunnels, shafts, mining faces, etc.

In the prior art, there is a coal mining dust reduction device with Chinese patent number CN219119304U, which comprises a mobile base, a push handle fixedly connected to the upper left end of the mobile base, a water collecting box fixedly connected to the upper left end of the mobile base, and a mobile device fixedly connected to the front end of the fixed frame. The coal mining dust reduction device described in the utility model can adjust the spraying range of the spray head so that the spraying dust reduction range is wider, thereby improving the dust reduction efficiency. However, the existing coal mining dust reduction device has the problem that the device cannot remain horizontal when climbing a slope. Because the device cannot remain horizontal when climbing a slope, the existing coal mining dust reduction device has the problem that it is easy to be damaged by tipping over when climbing a slope. Therefore, a dust reduction device is proposed. After the first motor (2) drives two rotating wheels (8) to rotate, the device can remain horizontal when climbing a slope and is not easy to tip over, so that the device is not easy to be damaged by tipping over when climbing a slope.
