Description

Automatic conveying device for coal mine mining

Technical Field

The application relates to the technical field of coal mining equipment, in particular to an automatic conveying device for coal mining.

Background

Coal mines are areas where mankind is mining coal resources in coal-rich mining areas, and are generally classified into underground coal mines and open pit coal mines. When the coal seam is far from the earth surface, coal is generally selected to be extracted from underground mining roadways, which is an underground coal mine. When the distance between the coal seam and the ground surface is very short, the earth surface soil layer is generally stripped directly to excavate coal, and the coal is an open pit coal mine. Most of coal mines in China belong to underground coal mines. Coal mine range includes large areas of above-ground and below-ground and related facilities. Coal mines are reasonable spaces that humans excavate when mining coal-rich geologic formations, and generally include roadways, shaft pits, and face formations, among others.

When the coal mine is excavated, the conveying is slower by manpower, so that the conveying device is adopted for conveying; however, the conventional coal mine excavating and conveying device has some defects when in use, firstly, the conventional coal mine excavating and conveying device is not automatic enough, more manual operations are needed, and secondly, the belt of the conveying device is easy to loosen and skid after long-time use, so that the conveying efficiency is affected.
