Description

technical field [0001] The invention relates to the field of coal mining machinery and equipment, in particular to the field of coal mining mechanized equipment, and is a plow knife mechanism suitable for coal plows that is easy to adjust. Background technique [0002] Coal plow is a comprehensive mechanized coal mining equipment used for mining thin coal seams of 0.8-2m. It integrates the functions of "mining, loading and transportation", and is equipped with an automatic control system to realize fully automatic coal mining equipment for unmanned working faces. The coal plow is a shallow-cut coal machine with external traction. It uses planing to drop coal, and the coal is loaded into the working face conveyor through the pear face of the coal planer. The coal plow and the scraper conveyor form a coal plow unit. Coal plows generally consist of plow motors, hydraulic couplers, reducers, plow sprockets, and plow chains that are located at both ends of the conveyor to drive ...
