Scraper conveyorTraction 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 90-degree 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 shearer's orbit, 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 components by what? Various types of scraper conveyor of the main structure and composition of the basic components 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 components such as chains. Machine head by the head frame, motor, fluid coupling, reducer, such as pieces of the composition and sprocket. The transition from the central trough, the central groove, scraper chain and the composition of such pieces. Rear scraper plane for the return of the device chain. Heavy-duty 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 186-189 AD between the invention of "roll-over" - 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; low transport capacity, a maximum of only a few dozen tons per hour; conveyor only tens of meters in length;-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; to pull shift hydraulic support for fixed-point shift care ; clean up floating face coal; hoisting cables, pipes, tubes, etc. emulsion. Scraper conveyor in fully mechanized coal face shearer and hydraulic support and co-ordination 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 component), as components 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 completion 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, no-load power consumption of a greater power for the total about 30%. 2, not long-distance 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 30-40 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, more than a single chain, such as V-type, SGD-11 type, SGD-20 type, such as low-power light scraper conveyor. The second stage is the early 40's from Germany to produce flexible scraper 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 SGW-44-type scraper conveyor is the phase of the representative products. Into the 60's as a result of the emergence of hydraulic support, in order to meet the needs of fully mecha。
