Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining, and particularly relates to a coal crushing device for coal mining. Background Technique

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, underground roadways are usually dug to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, the surface soil layer is generally directly stripped to mine coal, which is a surface coal mine. Generally, after coal mining, a crushing device is needed to crush it for subsequent transportation and use.

[0003] When some existing coal crushing devices crush coal, the crushing device is usually fixed in the crushing cavity. When it is necessary to crush coal into different sizes, the crushing device needs to be replaced, which is not convenient for operators to use. Content of the Utility Model
