Coal mining operations have evolved from semi-mechanical in the 1950s to comprehensive mechanization in the 1980s. Comprehensive mechanized coal mining is widely used in shallow deep-seated double (single) drum combined coal mining machine (or plow), flexible scraper conveyor and hydraulic self-moving bracket, etc., so that the mining face is broken and coaled, loaded Coal, transportation, support and other links to achieve comprehensive comprehensive mechanization. The double drum shearer is a coal falling machine. The electric motor transmits the power to the spiral drum to drop coal through the cutting part of the reducer, and the movement of the machine is realized by the electric motor passing through the traction part transmission device. There are basically two types of traction, namely anchor chain traction and anchorless chain traction. The anchor chain traction is achieved by the engagement of the sprocket of the traction portion with the anchor chain fixed to the conveyor.
