This machine power isbig, the multi-electrical machinery crosswise arrangement, plete machine structure pact, uses the exchange frequency conversion velocity modulation system, the frequency conversion velocity modulation uses aircraft-borne-like. Cuts the electrical machinery, the pulling motor and so onmain part tobepossible toextract from the worked-out section, easy to replace, facilitates the service. The pulling motor outputs torque decelerates after the second-level cylindrical gears and the second-level gear reduction gear, bythe carrier outputs, with walks lining onthe feet and palms ofBuddha meshing through the driving gear, bywalks again round and onworking surface scraper conveyer ’s rack rail meshing causes the coal mining machine back and forth towalk, simultaneously the brake spindle output shaft isconnected through the key and the brake, realizes the electricity hauling department brake. About the hauling department, the middle electrically controlled box ’s joint stud, the positioning pin, the rocking shaft sells the axis four groups with about electricity hauling department hinge, these installments join coal mining machine various major assemblies awhole, plays the fastening and the connection role. Traction box and walking ministry independent design, supporting patibility The MG300/900-WD coal mi
