he high-capacitly armored face conveyor with rectangular tuming integrates the conveying, transferring and crushingfunctions of fully mechanized coal mining face. By applving the principle of rotary table, the scraper single chain conveying and90-degree turning are realized, and the transported coal is transferred to the belt conveyor through the transfering machineand the crusher.This product has four innovation points: realize the continuous transportation from the working face to themining area along the trouah without transferringify the eauipment supportina links, help to reduce the bottom chainback coal and coal dust concentration underaround:The desianrotary plate auide structure realizes the continyousrioht-anale changing movement of the chain scraper, and the desian of the rotary plate ensures that the scraper and the coaflow can tum smoothly.A new type of two-sided combined middle slot is developed. When the middle plate of the middle slot isbadly wom, the middle slot can be tured over and installed, which extends the service life.The sprocket teeth are designed tobe removable. When the outer teeth are badly worn, the teeth can be replaced, which is easy to operate and reduces the usecost.
