Scraper for double chain scraper feeder

摘要

The scraper is in three parts. It consists of a one-piece scraper plate which has sunken coupling extensions (8) at both ends, by which it can be connected to the connecting members (5') of the scraper chain (5) by coupling pieces (14) and vertical screw bolts (17). There is a three-point support for the coupling piece on the scraper plate. The coupling piece rests on one side on the vertical screw bolt via a lifter passing through the horizontal connecting member on parallel support surfaces either side of the scraper axis. The horizontal connecting member is thus free to move in the chain bed (13).
