Abstract

The utility model discloses a broken belt conveyor belt capturer, which is arranged on a plurality of points in high inclined belt conveyor rack. The conveyor upper belt is between upper and lower brake blocks. When the belt is in normal material transportation, the belt does not contact with the brake blocks to avoid the belt damnification. When the belt breaks, the upper belt containing materials drops down and slides forwards, drag the reverse-stoppable roller and the lower brake block below, the lower brake block displaces upwards during the sliding process, and the distance between the upper and lower brake blocks is getting smaller and smaller, and eventually the belt is compressed tightly until the belt stops, the purpose of broken belt to capture is gained. The use of the coal flow face lifting plate and the vertical roller on the two sides of the capturer is to stir the out stretching materials on the belt, when big block material is met to convey through, some angle is turned to let the big block material pass, and then the former state is reset automatically, thus the overloading of the belt is avoided. The utility model is always at working waiting state.
