Design and manufacture of scraper conveyor covers the movement of conversion, power transmission, the transmission mechanism, such as mechanical design. Through the integration of knowledge, choice scraper conveyor as graduation project. The design is based on the actual transportation environment is based on the port, in the design of new design ideas as possible, choose a more rational structure, and strive to improve the quality of scraper conveyor, reduce production and operating costs, while fully absorb learning scraper conveyor on the basis of machine design experience, reference to the relevant design information, complete the structural design of scraper conveyor. The main research questions are: optimization of planetary gear reducer, chain design, blade design, transport, chain scission detection devices. Design a practical application requirements. Through this design, exercise their own research and analysis, processing and finishing, the ability to use tools manual, initial grasp of the mechanical engineering design process, methods and technical specifications to improve engineering design calculations, theoretical analysis, charting capabilities, technical documents prepared .
