ABSTRACT:
A scraper unit for a scraper-chain assembly is composed of a one-piece scraper with extensions at the ends of its main body for engagement with horizontal links of the chains. The extensions have underside recesses which locate the shanks of the horizontal links and external cavities which locate the vertical links joined to these horizontal links. Deep vertical profiled pockets in the scraper end regions receive and shape-lock coupling pieces which encompass the inner shanks of the horizontal links and project laterally across the links, i.e., parallel to the scraper. The coupling pieces can be permanently joined to the links or detachable therefrom. The coupling pieces have tongues which support beneath the outer shanks of the horizontal links. Nuts engage on fixing bolts or the like projecting through both the scraper and the coupling pieces enabling the scraper to be detached. Where the coupling pieces are detachable they have additional threaded pins engaging in bores in the scraper and receiving nuts.
