The invention relates to a flow coal-mining machine, comprising a rack (4), a two-rail coal mining mechanism, a driving mechanism and a travelling mechanism, wherein the rack (4) is of a frame structure; the rack is provided with the two-rail coal mining mechanism; a gearwheel shaft (8) in the middle of the two-rail coal mining mechanism is provided with the driving mechanism which is fixed on a power electrical motor (15) on the rear end of the rack; the gearwheel shaft (8) on the upper end of the rack is connected with the travelling mechanism arranged on one side of the middle part of the rack (4) through a conveyer belt; the lower end of the rack is fixedly with two rails (1); the entrance of the two-rail coal mining mechanism is respectively provided with two slipping plates (6); theupper ends of the two slipping plates are respectively fixed on of the rack; the lower end of the two slipping plates are respectively arranged above the conveyer belt; and the rear end of the rack isprovided with a railing (25) with a moveable mechanism. The machine is particularly suitable for small and medium-sized coal mines, can transport coals to the conveyer belt, can clear a coal-scatterpile, and have simple structure, low cost, convenient use, time economization, manpower economization and high efficiency.
Description
technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a mobile shearer for medium and small coal mines. Background technique [0002] At present, the underground coal mining equipment in domestic coal mines has developed rapidly, but for a long time in the underground, due to the complex terrain and uneven distribution of coal seam structure, this has brought many difficulties to coal mining work. Large-scale mines with good coal seam structure and good conditions have used advanced large-scale turbine coal mining equipment and coal transportation equipment. Due to the large size of coal mining equipment and coal transportation equipment, the movement is not flexible, and there are many dirty coal left over from mining. Requires manual removal with shovel. Small and medium-sized mines generally still use electric drills and blasting to mine coal, that is, after the coal is loosened, the loose coal is sent to the conve...
