Description

Technical Field

[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. 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.

However, the automatic cable-dragging device for a coal mining machine in the prior art does not have the function of protecting the cable when in use, which causes scratches on the coal mining machine when pulling the cable, thereby reducing the use effect of the automatic cable-dragging device for the coal mining machine. To this end, we propose an automatic cable-dragging device for a coal mining machine to solve the above problem. Utility Model Content
