bit, so it into a modern coal mining process of the major equipment indispensable. Scraper conveyor functions to maintain continuous operation, production can be carried out normally. Otherwise, the whole coal face production status will be shown, so that disruption of the entire production. Scraper conveyor ponents by what? Various types of scraper conveyor of the main structure and position of the basic ponents are the same, it is by the head, middle and tail of three machine parts. In addition, for over conveyor equipment used hydraulic jacks and tight chain tight when the subsidiary ponents such as chains. Machine head by the head frame, motor, fluid coupling, reducer, such as pieces of the position and sprocket. The transition from the central trough, the central groove, scraper chain and the position of such pieces. Rear scraper plane for the return of the device chain. Heavyduty scraper conveyor tail and nose of the same are also provided with power transmission devices, from the install location to distinguish under the name on the nose and head. Scraper conveyor of work? Scraper conveyor of the working principle and basic structure, and our country in the years 186189 AD between the invention of rollover water is the same keel. However, the use of scraper conveyor transported materials kibbling is the beginning of this century developed in the United Kingdom industry. Scraper conveyor early, simple structure and light, then it is only used to transport coal, manual loading of coal。 conveyor only tens of meters in length。 to pull shift hydraulic support for fixedpoint shift care 。 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.
