Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a material conveying device used in 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, 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 peel off the surface soil layer to mine coal. This is an open-pit coal mine.

[0003] In the existing coal mining, when the transportation device transports the mined coal, the coal will shake off the surface of the conveyor belt, causing waste of coal and reducing the transportation efficiency. At the same time, when transporting the coal at different heights, it is necessary to use conveying machinery of different heights. It is very troublesome to replace the machinery. In order to solve the shortcomings of the existing technology, we propose a material conveying device for coal mining. Utility Model Content
