The invention relates to a cross side dumping
type variable-frequency drive conveying device for
coal mines. The cross side dumping
type variable-frequency drive conveying device for the
coal mines comprises a scraper conveyor and a scraper
loader. The scraper conveyor comprises a conveyor head, a conveyor body and an extensible conveyor
tail. The extensible conveyor
tail is composed of a
fixed frame and a movable frame. A first extensible conveyor
tail deflection slot, a second extensible conveyor tail deflection slot and a third extensible conveyor tail deflection slot are formed between the conveyor body and the movable frame. An extensible conveyor tail push unit I and an extensible conveyor tail push unit II are arranged on the movable frame on one side of the first extensible conveyor tail deflection slot and on one side of the second extensible conveyor tail deflection slot respectively. The cross side dumping
type variable-frequency drive conveying device for the
coal mines has the advantages that
energy conservation and emission reduction are realized, and requirements of a motor for high starting torque and soft starting can be met; since the conveying device can be started at
low speed and
high torque, collapsing force on a chain is reduced, post maintenance cost is lowered, the longest service life is realized, and the high requirement on
coal mining mechanization is met.
