摘要
本次设计是关于多功能带式输送机的设计，设计要求输送机可移动，可伸缩，输送倾角可调。对于可移动功能本设计采用在输送机添加四个滚动轮的方法；可伸缩功能是通过设计伸缩链轮实现的，然后利用液压臂来实现伸长和缩短和输送角度的变换。
大概的设计流程为：首先对带式输送机作了简单的概述；接着分析了带式输送机的选型原则及计算方法；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的输送机各主要零部件进行了校核。
普通型带式输送机由六个主要部件组成：传动装置，机尾和导回装置，中部机架，拉紧装置以及胶带。最后简单的说明了输送机的安装与维护。目前，胶带输送机正朝着长距离，高速度，低摩擦的方向发展，近年来出现的气垫式胶带输送机就是其中的一个。在胶带输送机的设计、制造以及应用方面,目前我国与国外先进水平相比仍有较大差距,国内在设计制造带式输送机过程中存在着很多不足。
本次带式输送机设计代表了设计的一般过程, 对今后的选型设计工作有一定的参考价值。

 Abstract

The design is a graduation project about the multifunctional belt conveyor. The design requires the belt conveyor to be mobile, scalable, and the transmission angle should be adjustable. In this design, we install four scroll wheels to achieve the function of moving; to make it scalable ,we can design specific drum arrangement ,and then use the hydraulic arm to realize the elongation, shortening and the adjusting of the transmission angle .
The main design process is : First, it is introduction about the belt conveyor. Next, it is the principles about choose component parts of belt conveyor. After that the belt conveyor abase on the principle is designed. Then, it is checking computations about main component parts.
The ordinary belt conveyor consists of six main parts: Drive Unit, Jib or Delivery End, Tail Ender Return End, Intermediate Structure, Loop Take-Up and Belt. At last, it is explanation about fix and safeguard of the belt conveyor. Today, long distance, high speed, low friction is the direction of belt conveyor’s development. Air cushion belt conveyor is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of belt conveyor.
This desegn is on behalf of the commen design process of the belt conveyor ,it provides reference value to the selection of design work in the future.
