ABSTRACT: The scraper conveyer is the main transport equipment of the coal picking face. Scraper conveyor of reliable, stable and efficient operation will directly affect the productivity and efficiency of coal face. The scraper conveyer has the heavy-duty and super heavy development trend in order to increase production capacity. Firstly, the article compares the characteristics of various types of conveyor in this paper. Select the single-chain scraper conveyor according to the actual situation. This design of center single-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.Secondly, this article designs the overall structure of the central single-chain scraper conveyor. 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. This paper completes the overall design of the double-chain scraper conveyor. And the Machine head, the central groove, chain- wheel sets and other important parts of the design is completed.  Finally, this article completes the detail part design of the reducer and chain- wheel set shaft, gears and other important parts in detail part design. This designed scraper conveyor has a large transport capacity and high reliability.    

Keywords: Scraper conveyor ; central single-chain ; transmission ; Central trough
