There are many types of scraper conveyors used in mines, and the forms and layout of each component are different, but the main structure and basic components are the same, consisting of the head, fuselage, tail and auxiliary equipment.The head part is the transmission device of the conveyor, including the head frame, motor, hydraulic coupling, reducer, head spindle and sprocket components.The function is that the motor drives the scraper to run in the chute through the coupling, the reducer, the spindle of the head and the guide sprocket wheel, and the coal is transported out.
Mine conveyor rope traction and wire rope core belt conveyor transport long distance, transport capacity, suitable for large and medium-sized mine uphill, downhill, inclined shaft lifting and long distance horizontal transport.The former USES steel wire rope as the traction mechanism and the conveyor belt as the bearing part. The fuselage structure is relatively simple, and the conveyor belt has no deviation problem and less energy consumption, so it can transport people.However, the head and tail of the machine have complex structure and large length, so the opening up of the chamber should be increased when used underground.The latter high-strength conveyor belt has both traction and bearing function, simple structure and reliable operation;But the joint process is more complicated and the investment is higher.The belt conveyor used in the mine shall adopt incombustible rubber belt or plastic belt.It is suitable for conveying coal in the middle roadway and the blasting and mining working face.The conveyor is a flexible traction mechanism of continuous transport machinery, its traction component is a scraper chain, the carrying device is the middle trough, scraper chain is placed in the middle trough of the trough surface, the middle trough along the whole line of transport, scraper chain around the head and tail of the sprocket wheel connected into a closed shape in the middle trough.
