毕业论文--混凝土搅拌机设计.doc

摘要
JS1500型混凝土搅拌机是一款大中型搅拌机,主要适用于较大的建筑工程,是非常重要的建筑机械。它是强制式卧轴搅拌机的一种,不但能搅拌干硬性混凝土,而且能搅拌轻骨料混凝土,是一款多功能搅拌机。在搅拌过程中,通过搅拌轴的回转运动来带动搅拌叶片对筒内物料进行剪切、挤压和翻转推移等搅拌作用,使物料在相对的剧烈运动中的得到充分的拌合,因而它具有拌合质量好、能耗低、效率高等优点。现代建筑工程中搅拌机的广泛应用,不仅减轻了工人的劳动强度,还提高了混凝土工程的质量,对我国的基础设施建设做出了很大贡献。在下一个五年规划中,国家加大了基础设施的建设的力度,这对混凝土机械行业的发展是十分有利的。该类型搅拌机的主要组成结构包括:传动系统、搅拌系统、上料系统、卸料系统、电气控制系统等零部件。在本次设计中,我们主要对传动方案进行了选择和设计计算,还确定了上料、卸料的方式以及叶片的结构,并对部分零部件进行了校核,使之满足不同场合的工作要求。

Abstract
JS1500 type concrete mixer is a large and medium-sized mixer,is mainly suitable for the large construction projects,it is an very important construction machinery. It is a kind of forced horizontal-axis mixer ,not only can mix the dry and rigid concrete, but also can stir light weight aggregate concrete,is a new multi-functional mixer。In mixing process, through the rotary motion of stirring shaft of mixing blades to drive the material in the cylinder of shear, squeezing and flip elapse, make the material such as mixing effect in the relatively intense exercise fully with white, so it would be of good quality, low energy consumption, higher efficiency. Modern architectural engineering of mixer widely used, not only reduce the labor intensity of the workers, but also improves the concrete engineering quality, has made a great contribution the infrastructure construction of our country. In the next five-year plan, the government increased the strength of the infrastructure construction of concrete, the machinery industry development is very favorable. This type of position structure including blender, transmission system, mixing system, feeding system, unloading system and electrical control ponents. In this design, we mainly on the transmission scheme selection and design calculation, also identified loading, unloading and ways of blade structure, and checks for some parts to meet different occasions work requirements.
Keywords: concrete mixer, quality, energy consumption, efficiency and structure
