FIELD: mechanical engineering; conveyors.
SUBSTANCE: invention relates to device for removing contaminants from conveyor belts in belt conveyors near drive and/or end tension drum conveyor belt. Proposed device contains system holder secured on carrying skeleton of conveyor belt which carries at least one scraper-type member. Scraper member consists of scraper plate arranged on plate bracket which adjoins, in working position, conveyor belt to provide cleaning of belt surface. Scraper member contains lower rotary joint with horizontal axle of rotation coupled with plate bracket and spring device to press scraper plate to conveyor belt acting onto plate bracket. Said device is made and arranged so that plate bracket is spring is spring-loaded, being tilted around horizontal axle of rotation when scraper plate is in operating position when scraper plate gets onto solid contaminants on conveyor belt, it can easily deflect and return again into operating position of conveyor belt. Scraper plate 8 is mounted on plate bracket 7 for turning in upper rotary joint 12 with horizontal axle 14 of rotation and is held by pretension of spring of upper spring device whose spring acts in opposite direction relative to lower rotary joint 11 and its spring device.
EFFECT: increased service life at high speeds of belt and large masses of material to be removed from belt near drum.
