摘 要 关键词：AbstractTConstruction machinery concrete mixing equipment is an important device, it is one of the key equipment of concrete production. Since the concrete mixing equipment is working objects sand stone and cement mixture, and the amount of large, poor working conditions. Therefore, concrete mixing equipment in the high-tech, high-performance, automated, intelligent direction of great necessity. Modern building engineering mixer widely used, not only to reduce the labor intensity, but also improve the quality of the concrete project on Chinas infrastructure construction has made great contributions. 牋The design focuses on the twin-shaft compulsory concrete mixer design, comprising mixing bucket design, hopper design. In accordance with relevant national standards, in parts, materials, construction technology and other aspects of the design of the structure is reasonable, to meet the requirements of the production needs of concrete mixing equipment. It focuses on the mix design mix device manufacturing. Of spare parts involved in the design, verification, each member put forward detailed arguments within tolerance, to be formally identified the size of the parts, the overall layout, to meet various requirements. Twin shaft compulsory concrete mixer in the mixing process, to drive through the rotary motion of the stirring blades of the stirring shaft tube material to cut, squeeze and flip goes on and so stirring, so that the material obtained in a relatively vigorous exercise in full the mixing, so that it has good mixing quality, low energy consumption and high efficiency.Keywords: Concrete mixer, quality, energy consumption, efficiency, long life 绪 论目 录 摘??要?...................................................................
