<p>The invention relates to an arrangement (1) for stripping material from the lower run of the conveyor belt of a belt conveyor. The arrangement comprises scrapers (11) organised in groups (G1, G2), arranged distributed across the width of the conveyor belt and resting resiliently against the lower face (8) of the lower run. All scrapers are arranged obliquely with respect to the running direction (LR) of the lower run (9), the scrapers (11) of a first group (G1) being oriented at an angle in relation to the scrapers (11) of an adjacent second group (G2). In order to achieve an improved careful cleaning action, in particular in the case of an undulating conveyor belt, the arrangement according to the invention is characterised in that each scraper (11) is supported by way of at least two coiled torsion springs (20, 21) at least indirectly on the supporting structure of the belt conveyor, wherein each torsion spring (20, 21) is connected by the upper end (28, 29) thereof to a front end portion (11.1) or a rear end portion (11.2) of the scraper (11), viewed in the running direction (LR); each torsion spring is rotatably connected by the lower end (30, 31) thereof to a cross strut (5, 6, 7) of a support frame (2) mounted on the supporting structure of the belt conveyor and has at least one leg section (24, 25; 26, 27) directed substantially obliquely to the running direction (LR) and obliquely downwardly opposite to the running direction.</p> |
