This machine power is big, the multi-electrical machinery crosswise arrangement, the complete machine structure is compact, 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 on main part to be possible to extract from the worked-out section, easy to replace, facilitates the service.The pulling motor outputs torque decelerates after the third-level cylindrical gears and the second-level planet gear reduction gear, by the planet carrier outputs, with walks lining on the feet and palms of buddha meshing through the driving gear, by walks again round and on working surface scraper conveyers rack rail meshing causes the coal mining machine back and forth to walk, simultaneously the brake spindle output shaft is connected through the key and the brake, realizes the electricity hauling department brake.About the hauling department, the middle electrically controlled boxs 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 a whole, plays the fastening and the connection role. The hauling department with walks to make a body, caused the fuselage overall size to be compact, reduced the fuselage width.The G400/930-AWD coal mining machine, the ease of operation, the reliability is high, the accident rate is low, the starting efficiency is high, may satisfy the high production highly effective working surface the need.Key word: The coal mining machine； the hauling department； walks；Planet gear1
