The utility model arranges a plurality of rollers at the front end of the connection box, and the rollers are used to crush the clamping rod fault or large pieces of coal, thereby improving the transportation efficiency and avoiding the blockage problem.

[0005] The utility model proposes a detachable crushing device for thin coal seams, which specifically comprises a coal mining machine traction part, a connecting box, a walking part, a scraper conveyor and a roller cutter. The coal mining machine traction part, the connecting box and the walking part are connected in sequence, and the walking part is placed on the edge of the scraper conveyor; a plurality of roller cutters are arranged at the front end of the connecting box.

[0006] Furthermore, the traction part, the connection box and the traveling part of the coal mining machine are connected by a plurality of screw rods.

[0007] Furthermore, a fixed base is provided at the front end of the connection box, and a roller is provided on the fixed base.

[0008] Furthermore, the hob is positioned on the fixed base by means of positioning pins.

[0009] Furthermore, the hob is mounted on a fixed base by bolts.

[0010] The beneficial effects of the detachable crushing device for thin coal seams described in the utility model are:

[0011] (1) The utility model discloses a detachable crushing device for thin coal seams, which overcomes the problems of existing thin coal seam coal mining machines having a short body, a small coal passing space, and coal blockage caused by large pieces of coal or gangue. By arranging a plurality of rollers at the front end of the connecting box to crush large pieces of coal or clamping rod faults, the efficiency of coal mining is improved and the labor intensity of underground workers is reduced.
