ABSTRACT:Scraper conveyor is conveying dust-like, small particles and small pieces of bulk materials such as continuous conveyor equipment, can horizontal, inclined and vertical transmission. Scraper conveyor is driven by a motor reducer and drive shaft drive shaft and sprocket assembly, and drive chain and sprocket assembly through the chain scraper which will be transported material.

　　　Conveyors for the overall structural design and overall demonstration program; transmission scheme of the system are analyzed and selected, the final choice of using electric motors, three tapered cylindrical reducer, double-and high-intensity ring side chain composed of scraper conveyor, after basic scheme selected by the calculation of the basic parameters of the design of the important components were designed and used to finalize the various important parts of the important parameters of the final design and basic parameters selected, complete a scraper conveyor assembly diagrams, parts diagrams and parts department loaded important component graphs, while the design of the scraper conveyor also has a simple structure, even by force, stable, less prone to clogging and other characteristics.
