 Abstract    Scraper conveyor is an important part of food transport. It Plays an important role in the transport of soybean, corn and other food crops. The main components are: head power part, scraper chain, the tail section and the middle baffle. The motor drives the main shaft to rotate through the chain wheel shaft, and drives the scraper chain. Scraper chain driven by food, and to promote the food with the scraper together forward movement through the friction between the grain crops, in order to achieve the transmission effect. Design and manufacture of the scraper conveyor covers the motion conversion, power transmission, the transmission mechanism of casting forging, content structure design of mechanical design and manufacturing process. After the analysis, selection of scraper conveyor as my graduation project, so it can more comprehensive study by the application of knowledge and skills, analysis and calculation, structure selection, drawing skills and basic knowledge of manufacturing comprehensive application of mechanical design, to our knowledge, summaries, an intensive training and promotion of the comprehensive application of knowledge, skills, are beneficial. In this paper from the point of actual engineering, the design of conveyor 3D overall train of thought, a detailed discussion of the implementation method of the scraper conveyor overall shape, assembly, assembly simulation, interference detection and motion simulation, to achieve the establishment of three dimensional model of scraper conveyor.

Keywords: Scraper conveyor assembly simulation 3Dmodeling
