Belt conveyer is one of most equipment used in bulk transport. Belt conveyer is continual motion machine of sideless conveying articles, using rubber belt to be conveyer belt is called rubber belt conveyer, and brief name is sealing-tape machine. Belt conveyer is an important component part of lifting and transport machinery. Its structure is very simple, and has low cost, long distance transport and very high productivity. It is mainly used in metallurgy、mining coal、power plant、port and industrial enterprises. It will make the bigger and bigger contribution for our country various mining industry loading and unloading mechanization and modernization.
In the existing technology, in coal mine common digs the gangue coal transport vehicle is mainly the scraper conveyer, its flaw is easy to appear the card chain link, to break the chain link, and the nose chain wheel breaks the tooth, the card scraper, breaks the scraper, the bottom chain is easy to overflow the breakdown and so on. Moreover, because machine is unwieldy, installment and removal link is complex, equipment failure rate is high, it creates the worker’s labor intensity in a big way, the working efficiency is low, the fitting invests is big and so on. Furthermore, in the scraper movement process the extrusion or blows the card of the gangue and the scraper to trough is easy to produce the spark, to form the hidden danger, is disadvantageous to the safety in production.
This article mainly introduced one kind of simple coal mine shaft tunneling gangue coal transportation belt conveyer in view of this kind of situation. First, it introduced the work characteristic of belt conveyer, the development survey, the principle of work and the classification; Next, it introduced the adhesive tape friction drive principle; Finally, it has carried on in detail design and calculation according to the working condition of belt conveyer, like drive, rack and so on. Its structure is simple, the installs and disassemble is convenient, the cost is low, the equipment safe is reliable, in coal mine shaft it is applied widely.
