<p>The scraper is for a conveyor belt and has parts, each consisting of a scraper strip, fixed to the support by a flexible coupling. These are hollow on a support adjustable in height relative to the belt. The hollow couplings are shaped to slide along the support but do not turn relative to it. They have a square section, and pass around the ends of cylindrical rods held in lockable seatings, adjustable in height relative to the belt. Alternatively the sections can be triangular.</p> |
