Belt floating prevention device for underground coal mine conveyor belt

The utility model relates to a belt anti-floating device of an underground coal mine conveyor, which belongs to the technical field of coal mine electromechanical transportation and comprises an upper belt and a lower belt, an unloading roller I is arranged at the position where the upper belt moves to a slope turning point, and a turn-back roller II is arranged at the position, far away from the slope turning point, between the upper belt and the lower belt; the upper belt is redirected through the unloading roller I to form a redirected belt, the redirected belt continues to be folded back through the folding-back roller II to form a folding-back belt, the redirected belt is parallel to the upper belt, and the folding-back belt is parallel to the lower belt. The upper belt bears materials, the direction of the materials is changed through the unloading roller I, the materials are unloaded on the buffer bed, and the upper belt receives the materials through the buffer bed after being turned back through the
