【正文】 craper conveyor, with Shearer, metal stent with a mechanized mining. Cough such scraper conveyor to adapt to uneven floor and the level of convex curved surfaces, such as conditions shift, is not required for demolition, and coal have also increased, such as the Model SGW44type scraper conveyor is the phase of the representative products. Into the 6039。power small, traction chain the intensity is not high. After years of improvement and development, with fully mechanized coal mining face of the scraper conveyor, in addition to coal, there are four functions: to the shearer for orbit。 Scraper conveyor Traction with scraper chain, in the bed of the delivery of bulk material conveyor called scraper conveyor. Scraper conveyor trough in the middle of the adjacent level can be limited vertical bending is called flexible scraper conveyor. One body in the face and transport interchange roadway was 90degree bending of the face conveyor set called scraper conveyor corner. Coal face in the current, the scraper conveyor is not only the delivery of coal and materials, but also a shearer39。 conveyor only tens of meters in length。 hoisting cables, pipes, tubes, etc. emulsion. Scraper conveyor in fully mechanized coal face shearer and hydraulic support and coordination work. Scraper conveyor of the working principle is to open the chute, as coal, waste or materials, such as pieces of the bear will be fixed in the chain scraper (scraper chain ponent), as ponents of traction. When the Department of nose after transmission, the chain wheel drive shaft rotating head, so that the cycle runs driven scraper chain stores along the chute to move the head up to the unloading machine. Scraper chain sprocket for no class to bypass the closed cycle operation, the pletion of the delivery of materials. Scraper conveyor What advantages and disadvantages? Scraper conveyor is the main advantages and disadvantages: advantages: 1, the structure of a solid. Can withstand coal, waste or other materials of red, hit, hit, pressure and other external force. 2, able to adapt to uneven floor coal face, bending over the need for vertical or horizontal can withstand the bending direction. 3, body short, easy to install. 4, can act as Shearer orbit. 5, can reverse run, easy to deal with the accident at the end of chain. 6, fluid can be the fulcrum of the preceding night stand. Disadvantages: 1, noload power consumption of a greater power for the total about 30%. 2, not longdistance transmission. 3, prone to swap chain, jumped the accident chain. 4, consumption of steel and more. Costs. Scraper conveyor through several stages of development? Scraper conveyor in the production of coal mine development and construction, more or less gone through three stages. The first phase of 3040 years, is detachable scraper conveyor, which can only be a straight line in the face with the laying, with the face forward, need manual demolition, removal, assembly. Scraper chain plate, mor
