ABSTRACT
Scraper conveyor is a kind of flexible traction for the transport machinery，Primarily for the use of coal face. Fully mechanized coal mine in the coal face of the main tasks is to undertake the mining of coal Shearer continuously reproduced to the machine，Ensure that the fully mechanized coal face of the coal for export. It requires a high degree of the fuselage of small，easy loading；The use of transport capacity to meet the needs of production sites；Solid structure，can resist pressure，smashing and collision；Change the distance，the lengthening and shortening the convenience；can not demolished by mechanical removal.
According to the design parameters and environmental requirements，the scraper conveyor through the development of the situation，the trend of development，structure，working principle，types and roles of the scraper conveyor transport capability of calculation ，The level of the bending of the geometric parameters，the operation of the resistance，the chain tension and the traction，electrical power，the resistance to passage of the chute，the chain of pre-tension and tight links of the chain of calculation and the calculation of strength，to complete scratch Board conveyor structure improvement，drawn-scraper conveyor the map，the nose gear，such as structural design. a paper scraper conveyor English translation was Completed.
