A belt scraper for belt conveyors suitable for mounting on the head pulley comprises blade subassemblies (2), a mounting structure (1) and two side-mounting subassemblies (3) to ground the whole assembly and provide translatory adjustement motions in perpendicular directions. A torsion spring and a compression spring provided in each blade subassembly (2) provide automatic continuous adjustment of scraper blades and keep scraper blades in continuous contact with the belt surface. The torsion spring is given a pre-tension during the assembly of the blade subassembly (2). The compression spring forward force for automatically adjusting scraper blades for less wear. |
