Description

Technical Field

[0001] The utility model relates to the technical field of coal mines, and more specifically to a split-type cutting part protective cover of a continuous miner. Background Art

[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 and mining faces.

[0003] A continuous miner is a comprehensive tunneling and short-wall mining equipment that integrates cutting, traveling, transporting and spray dust suppression. The continuous miner consists of a cutting mechanism, a loading mechanism, a traveling mechanism, a hydraulic system, an electrical system, a cooling spray dust removal device and a safety protection device.

[0004] When the continuous miner is shut down, in order to ensure the safety of personnel on the working site, a protective cover needs to be installed on the cutting part of the continuous miner. The currently installed protective cover is heavy and old, consumes manpower, and is inconvenient to install. Therefore, we provide a split-type cutting part protective cover for the continuous miner. Utility Model Content
