After the electrical machinerystarts after the flexible coupling, the speed reducer, the crank linkmotion gear drives leans the material 13° ledger wall to make thestraight reciprocating motion on the roller, the coal evenly unloadsto other equipment on. It may effectively enhance the working surfaceexcavation equipment the use factor, fully displays the transportationsystem the potential, guaranteed continuously balanced produces. But, bunker flees the warehouse accident frequently to occur in our countrycoal mine. Flees the warehouse matter same as ever to create theequipment major damage, the mine shaft suspends production, when fleesthe warehouse coal amount is bigger, but also can block the tunnel,creates transports the lane to ventilate impeded, causes accident andso on gas explosion. In order to prevent and reduce coal mine coal bunker channeling the warehouse equipment damage, casualties, Roadway congestion and impact production, and other hazards, for the design of a reciprocating coal channeling anti-aircraft positions devices, for the coal bunker channeling warehouse control provides a new way. Key words : coal bunker channeling warehouse; Coal; Anti-channeling devices warehouse.Key Words Crank slide organization；Bunker flees the warehouse；Guards againstflees the warehouse installment；The reciprocation type gives thematerial machine.
