Description

Technical Field

[0001] The present application relates to the field of coal mining machines, and in particular to an automatically adjustable coal shoveling plate structure of a coal mining machine. Background Art

[0002] For mining thin or extremely thin coal seams, the development of high-powered cantilevered shearers is becoming a trend. A cantilevered shearer is a type of machine that places the main body of the shearer to the side of the conveyor, close to the coal wall. This addresses issues such as the clearance between the shearer and the conveyor, the coal-passing space between the shearer and the conveyor, and the layout of the shearer's components.

[0003] However, for the low mining thickness of extremely thin coal seams, the gap between the traditional suspended machine body and the top plate (above) and the bottom plate (below) is relatively small. When installing a small-diameter roller, coal rock behind the roller is easily retained and accumulated under the suspended machine body, resulting in increased walking resistance of the entire machine.
