摘 要

全套图纸，加153893706

搅拌可以使两种或多种不同的物质在彼此之中互相扩散，从而达到均匀混合；也可以加速传质和传热过程。在工业生产中，搅拌操作是从工业开始的，围绕食品、纤维、造纸、石油、水处理、建筑等，作为工艺过程的一部分而被广泛应用。本文就以建筑为中心设计一款小型混凝土搅拌机。

本设计的小型混凝土搅拌机是强制式搅拌机中的一种，搅拌非常均匀，质量好，生产效率高，成本低。其主要组成结构包括：电动机、带传动、减速器、链传动、搅拌结构及机架等。主要设计计算内容是小型混凝土搅拌机搅拌装置的设计及其校核，搅拌轴的连接及强度校核，各部分在机架中的安装位置设计已达到小巧方便的设计要求。

本设计完成了总体结构的拟定，通过设计计算和校核，确定了各组成部分的结构尺寸和形状，实现了混凝土搅拌的功能。

ABSTRACT

Mixing can make two or more different materials in the spread of each other, so as to achieve the smooth; mix Also can accelerate and mass and heat transfer process. In industrial production, stirring, from the start of the industrial operation, around food, fibre, paper making, oil, water treatment, construction and so on, as part of the process and has been widely used. This essay, taking construction as the center design a small concrete mixer for reference.

The design of small concrete mixer is a compulsory mixer, the mixing is very uniform, good quality, high efficiency and low cost. Its composition include: motor, belt drive, gear reducer, chain drive, mixing structure and rack. Calculate the content of the main design is the design and checking of the small concrete mixer, agitator, stirring shaft connection and strength check all parts of the installation location in the rack has been designed to achieve compact and

convenient design requirements

The design is completed the overall structure of the formulation, design calculation and verification to determine the structure size and shape of the various components of the concrete mixing.

Key words: Mixer; Vertical shaft; Concrete; Mixing unit; Transmission system
