Scraper for double centre chain scraping flight conveyor for underground mining

摘要

A chain bracket (4) is convex relative to the longitudinal scraper axis. During assembly, and with fitted double-centre-chain, the bracket initially comes into contact with the two legs (3a) of the horizontal chain links (3), which face the centre of the scraper. When a defined assembly force is reached, the bracket additionally clamps the inner and outer legs (3b) of the links with approx. the same force. The bracket is held positively in apertures (15,16) in the scraper body (1), in direction of movement and at rights angles to it.
