Coal mining scraper conveyor is a continuous conveyor with disturbing traction mechanism. Commonly used in coal mining face. Because the coal mining face is relatively narrow, the lighting is insufficient, coal mining scraper conveyor has a long laying distance, the transportation task is hit, that is, transporting coal, and it also functions as a running track of the coal mining unit. Therefore, the operation management of the hanging conveyor is difficult, which may cause Accidents such as mechanical failures and personal injuries directly affect the normal production of coal.
Coal mining scraper conveyor can be used on the working face with coal seam inclination angle not exceeding 25 °. However, with the scraper conveyor of coal mining unit, the inclination angle is generally small, and anti-skid measures should be taken in the mining area when the coal seam inclination angle is large. At present, most of the working faces adopt curved scraper conveyors to meet the requirements of general mining and comprehensive mechanized coal mining. For different types of scraper conveyors, the components and arrangements are different, but their basic components are the same.
Its traction mechanism is a scraper chain, and its bearing device is a chute. In the fully mechanized mining face, in order to cooperate with the coal mining machine and the hydraulic support, a coal blocking board and a guide pipe (for a chain traction coal mining machine) are provided on the side of the goaf of the chute. The power device of the conveyor uses explosion-proof asynchronous motors. After calculating the required power according to the design requirements, two YB2-355M2-4 explosion-proof asynchronous motors are selected. The motor is connected to the reducer via a fluid coupling. The YOX-600 type fluid coupling was selected according to the power and speed. The reducer is a self-designed three-stage cone-cylindrical gear reducer. The reducer is connected to the sprocket and drives the ring chain that bypasses the sprocket. The ring chain bypasses the head and tail sprocket for stepless closed loop run. The endless chain is connected to the scraper, which pushes the coal in the chute to the unloading point at the machine head to unload. The chute is connected by the middle groove, the adjustment groove and the transition groove. I use dumbbell connection to connect them.
