Currently, a scraper conveyor is generally provided with two driving devices which are respectively arranged at the head part and the tail part of the scraper conveyor; the driving device transmits traction force through the traction scraper chain, overcomes various running resistances and drives the scraper conveyor to run.
Along with the length of the fully mechanized coal face becoming longer, the length requirement for the scraper conveyor is gradually increased, and the starting load of the scraper conveyor is increased due to the fact that the diameter of a scraper chain is thickened and the weight is increased after the length of the scraper conveyor is increased. Aiming at the problems, a mode of additionally arranging a drive at the middle part of the scraper conveyor is adopted to solve the problems; for example, the utility model patent with the application number of CN202111066989.2 discloses a multistage driving scraper conveyor, which is characterized in that a plurality of driving parts are arranged on a machine body, and a sprocket assembly is driven to operate by the driving parts together, so that a scraper is driven to transport a coal mine on a carrying plate, and a high-power driving part is not required to be arranged at the head and the tail of the machine body, thereby saving roadway space, uniformly distributing driving force and realizing stable starting and stable operation of the scraper conveyor under a heavy load condition. For example, the patent of the utility model with the application number of CN202120668341.1 discloses a multipoint intelligent driving scraper conveyor, wherein a driving structure is not arranged at the tail part of a scraper conveyor head, and the driving structure is distributed on a middle groove body, so that the tension of a scraper chain is reduced, the diameter of the chain is reduced, and the traction force is reduced.
