Description
Technical Field
[0001] The utility model relates to the technical field of coal mines, in particular to a transportation device used for coal mining. Background Art
[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the coal is usually mined by tunneling underground, which is an underground coal mine. When the coal seam is very close to the surface, the coal is usually mined directly by stripping the surface soil layer, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines encompass large areas above and below ground, as well as related facilities. Coal mines are the reasonable space excavated by humans when excavating coal-rich geological strata, usually including tunnels, shafts, and mining faces. Coal is the most important solid fuel and a type of combustible organic rock.

After reaching the unloading position, they still need staff to assist in unloading, which is not only laborious but also inefficient. For this reason, we propose a transportation device for coal mining. Utility Model Content
