The design is a graduation project about the belt conveyor used in coal mine. 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 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. 源￥自%六^^维*论-文+网=www.lwfree.cn
