摘要
本次设计的混凝土搅拌机及螺旋输送机是我们的主要设计机型。它是强制式卧轴混凝土搅拌机中的一种,强制式混凝土搅拌机不仅能搅拌干硬性混凝土,而且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。其主要组成结构包括:搅拌装置,搅拌传动系统,上料、卸料系统,供水系统,机架及行走系统,电气控制系统,润滑系统等。主要设计计算内容是混凝土搅拌机机架的设计,主要包括:机架结构方案的确定、机架上所有部件之间相互位置的确定、机架上所有部件与机架的连接方式及安装位置、机架外形尺寸的确定、机架钢结构的选材,机架稳定性的校核、完成机架总成图及零部件图。
对螺旋输送机结构进行设计与计算,对整个装置中的传动系统进行了运动力学分析及结构设计,对其驱动装置做了深入设计,并着重对其主要零部件进行了具体设计,包括螺旋输送机的螺旋直径,螺距,轴径进出料口,叶片形式,中间悬挂轴承,槽体,螺旋轴的计算选型。
电动机是通过螺旋输送机的功率来计算选型。减速器中齿轮通过齿面接触疲劳强度来计算,通过齿根弯曲疲劳强度验算;轴按许用弯曲应力计算法校核轴径。

Abstract
The design of the concrete mixer and the spiral conveyer is our main design models. It pulsory horizontal axis in a concrete mixer, compulsory mixing concrete mixer can not only dry hard concrete, but also stirred lightweight aggregate concrete, concrete can achieve a strong role in stirring, stirring very uniform, high productivity, quality Low is a new type of domestic mixer with pact structure, good looks. The ponents of its structure, including: mixing device, stirring drive system, feeding, unloading system, water supply systems, rack and walking systems, electrical control system, lubrication of the main content is js2000 concrete mixer rack design, These mainly include: rack structure of the programme of identification, rack between all ponents determine the location of, all ponents on the rack and rack of connections and installation of position, the determination of rack form factor, the selection frame steel structure , Checking the stability of the rack, complete plans and parts rack assembly plans.
For the construction industry background, which is required by the screw conveyor design and structure in this design. The entire device in the transmission system for the movement of mechanical and structural was designed. The design of its drivi
