摘要
In the scraper for chain bands of double-center chain scraper conveyors, the chain shackle is shaped in such a way in the direction of the scraper longitudinal axis that, during mounting with an inserted double-center chain, the chain shackle first comes to bear on those two legs of the horizontal chain links located towards the center of the scraper, in order, when the screw connection is tightened further, additionally to clamp the outer legs of the chain links. When a defined mounting force has been reached, the inner and outer chain-link legs are clamped with the same force. The concave curvature of the shackle, in contrast to the straight shackle, prevents the shackle from lifting off from the inner chain-link legs due to the bearing effect of the outer chain-link legs. An always uniformly distributed and permanently firm and reliable chain clamping is thereby guaranteed.
