普通型胶带输送机 The design is a graduation project about the belt conveyor with a large dip. At 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 with a larger dip abase on the principle is designed. Then， it is checking computations about main component parts. Just as ordinary belt conveyor， the belt conveyor consists of six main parts: Drive Unit， Jib or Delivery End， Tail Ender Return End. Intermediate Structure， Loop Take-Up and Belt. The only different is it uses pattern belt， which used to increase friction to avoid the move between the belt and goods. 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 conveyors 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 problem is discovered in the computations of the tail stand.
