摘 要
输送机械又称连续输送机械，它是沿着一定的输送路线运输货物的机械。在现代化的大企业中，有大量的原料、半成品和成品（如矿石、焦炭、耐火材料、水泥、化肥、建筑材料、谷物等）需要机械搬运，除了起重机械搬送一部分可以装箱或堆垛的大件物品外，大量的粒散料和小件物品的运输，是靠各种形式的运输机来完成的，在有些工艺流程中，运输机械还是必不可少的生产机械。
运输机械的形式很多，本设计为输送机械的第一类，即固定式带式输送机的设计。
带式输送机是用连续运动的无端输送带输送货物的机械。随着全球经济的增长，带式输送机技术已成为当代科学技术发展的前沿之一。当今世界需要设计和生产“环保”型输送机，要求输送量超过10000t／h，并且要节约能量。输送机技术进步的一个重要特点是基础研究发展为应用技术，进而实现商业化。
带式输送机是用途最为广泛的一种运输机械。主要应用在沿水平方向或沿坡度不大的倾斜方向，连续的大批量地运送粒散状物料或单件物品。它具有生产率高、运送距离长、工作平稳、结构简单、可以在任意位置上装卸、自重小、工作可靠、操作简便、耗能少等重要优点。
在本文中，详细地根据要求对带式输送机的全部过程进行了设计和计算，即总体设计计算、各部件的设计选用，并绘制了总装图及其主要部件的零件图。

Abstract
Transport machine is called the consecution transports machine, it is a machine which conveyances goods along certainly transport route .In modern big business enterprise, there are a great deal of raw material ,seml-processed goods and the finished product(such as the mineral stone,coke,fire-proof material ,cement, turn fatty, construct the material, corn…etc.)demand to be porteraged by machine ,ni addition to the derrick moving to send a part and canning pack or a product of a,the conveyance of a great deal of grain spreads and product ,theconveyance machine is also an essential production machine .
This design is the first Category of the transport machine ,and the design of the fix type take type transports machine.
The take type transports machine is a machine that transports the goods with the fix type take type transports machine .
The take type transports machine is a machine that transports the goods with the without cause belt and continuous sport conveyer .With the development of the world economy ,the technique of the take type conveyance has become one of the fuont of thecontemporary science technique development ,science technique development,desingning an produce the type of “environmental protection” transport machine ,requesting to transport the quantity over 1000ts/h,and to economize the enegy .An important characteristics of the progress of the technique of transports machine is that foundation research development chang into applying the techniqre ,then carry out commercial.
Belt conveyor is one of the most widely used transportmachinery , Mainly used in the oblique direction along the horizontaldirection or along the slope, large batch and continuousdelivery of grain bulk material or single articles. It has the advantages of high efficiency, longtransportation distance, stable work, has the advantages of simple structure, loading and unloading, at any position on small weight, reliable work, convenient operation, low energy consumption and other important advantages.
In this paper, detailed according to the requirement of the whole process of belt conveyor is designed and calculated, the design calculation, such as general designof each component, and draw the assembly drawing and the main parts of the parts diagram. Keywords: conveying machinery; fixed; belt conveyor
