Switch magnetic resistance control type speed regulation scraper conveyor

The utility model particularly discloses a switch magnetic resistance control type speed regulation scraper conveyor. Driving systems which are arranged at a machine head and a machine tail of the conveyor respectively are switch magnetic resistance motor speed regulation systems. Each switch magnetic resistance motor speed regulation system comprises a switch magnetic resistance controller which is used for controlling a switch magnetic resistance motor, wherein an output shaft of the switch magnetic resistance motor is connected with an input end of a reducer through an elastic coupling and an output end of the reducer is connected with a machine head chain wheel shaft group. According to the switch magnetic resistance control type speed regulation scraper conveyor, the low speed starting of heavy loads can be achieved and the power grid and mechanical impact is avoided; the real-time rapid regulation on the running speed of a scraper can be performed to adapt to various complex conditions, the reactive abr
