Abstract
The scraper conveyer is the synthesis picking work surface important constituent of the supplementary equipment. It is the first link of the coal shipping. Therefore, the scraper conveyer delivery capacity has decided the mining coal working surface productivity and the efficiency in a great degree; however, our country was lagged behind at present; the scraper conveyer installing equipment power is small. The delivery capacity is low; the transportation is away from short, the durability is bad; Reliability is low; and the life is short. The generalized analysis our country scraper conveyer use present situation, the design manufacture high performance scraper conveyer is imminent. This article first synthesized has compared each kind of type conveyer characteristic, has selected center simple chain according to the actual situation the scraper conveyer. But after, the scraper conveyer has carried on the overall structural design to center simple chain. To the nose transmission device, the aqueduct, the middle trough, the scraper chain, the scraper, the chain wheel, the airplane tail and other major component has carried on the technical analysis and the structural design, has completed center simple chain the scraper conveyer overall design. This design center simple chain about the scraper conveyer two sides are symmetrical, may install the reduction gear on two sidewalls, by left meets, the right mining coal working surface need. Moreover, it may very easily reequip the airplane tail the nose, but adapts each kind of peculiar circumstance. This design of center simple chain of the scraper conveyer characteristic includes: the structure is simple, the stress is even, moves steadily, the friction drag is small, the chute use factor high, the curving performance is good, It is not easy to appear stops up, has the very strong compatibility.
