本科机械毕业设计论文CAD图纸 QQ 401339828 PAGE I 摘 要 搅拌机在现代建筑工程中有着广泛应用，它不仅减轻了工人的劳动力，还保证了混凝土工程的质量问题，对我国的现在的基础设施建设做出了巨大贡献。 搅拌可以使两种或者两种以上的不同物质在彼此直接相互扩散，从而达到均匀混合的目的。混凝土搅拌机在搅拌过程中，通过搅拌筒的转动，带动搅拌叶片对筒内砂石、水泥等物料进行翻转、挤压等搅拌操作，使物料在相对剧烈运动中得到充分的搅拌。 本次设计的主要机型是自落式锥型反转出料搅拌机计。它是小型工程建筑凝土搅拌机中的一种，自落式锥型反转出料搅拌机能搅拌轻骨料混凝土，能使混凝土达到强烈的搅拌作用，搅拌非常均匀，生产率高，质量好，成本低。它是目前国内较为新型的搅拌机，整机结构紧凑、外型美观、便于运输。其主要组成结构包括：搅拌装置，搅拌传动系统，上料机构，供水系统，电气控制系统等。主要设计计算内容是自落式锥型反转出料搅拌机整体结构的设计，主要包括：整体结构方案的确定、搅拌筒外形尺寸的确定、电机的选择、上料机构的设计、减速器的设计、联轴器的选择以及完成机架总成图及零部件图。 本次设计主要通过对搅拌筒的设计，电动机的选择，减速器的设计，联轴器的选择，来实现搅拌机更高的机械效率及更好的工作稳定性。 关键词：混凝土搅拌机，外壳设计，减速器 Abstract The mixer is widely used in the modern construction, it not only reduces the workers labor, but also guarantee the quality of concrete project, made a huge contribution to our countrys current infrastructure construction. Mixing can make two or more than two kinds of different substances in each other mutual diffusion, so as to achieve the purpose of mixing. The concrete mixer in the mixing process, through the rotation of the mixing drum, drives the stirring bladeson the sand, cement and other materials are turning cylinder, extrusion mixing operation, to mix the materials fully in the relative strenuous exercise. The main models of this design is a self falling type cone type reverse feeding mixer. It is a small building concrete mixer, self falling type cone type reverse feeding mixer mixing of lightweight aggregate concrete, can make the concrete to achieve strong stirring, mixing uniformity, high productivity, good quality, low cost.It is a relatively new type of mixer, compact structure, beautiful appearance,convenient transportation. The main structure comprises: mixing device, mixing transmission system, feeding mechanism, water supply system, electric control system etc.. The main design content is a self falling type cone type reverse feeding mixer design, overall structure include: the overall structure scheme, the mixing drum shape size determination, motor selection, feeding mecha
