Abstract
A cleaning device for a conveyor belt for installation essentially transverse to the longitudinal direction of the conveyor belt. The cleaning device comprises a supporting structure (3) adapted to hold the cleaning device in place transverse to the conveyor belt (2), the cleaning device covering essentially the whole width of the conveyor belt (2) and consisting of a plurality of individual scraper segments (1′), each of which consists of a body having a scraping face (4), which scraping face (4) rests against the conveyor belt (2). The scraping face (4) on each of the segments (1′) is elastically connected to the supporting structure (3), the number of segments (1′) is relatively great and all the segments are covered by a flexible material.
Claims39
A scraping device for a conveyor belt for installation essentially transverse to the longitudinal direction of the conveyor belt which scraping device comprises a supporting structure adapted to hold the scraping device in place across the conveyor belt, which scraping device is covering essentially the whole width of the conveyor belt and consisting of a plurality of individual scraping segments each of which consists of a body with a scraping face, which scraping face breasts against the conveyor belt where the scraping device comprises a number of segments and the scraping face on each of the segments is individually elastically connected to the supporting structure and all the segments are covered by a flexible material, wherein the scraping device is mounted in a holder where a center area of the scraping device is fixedly connected to the holder with a fixed connection so that the scraping device can be bent toward the conveyor belt in that there is provided one or more adjusting devices on either side of said center area which push different parts of the scraping device against the conveyor belt bent around said fixed connection.
A scraping device for a conveyor belt for installation essentially transverse to the longitudinal direction of the conveyor belt which scraping device comprises a supporting structure adapted to hold the scraping device in place across the conveyor belt, which scraping device is covering essentially the whole width of the conveyor belt and consisting of a plurality of individual scraping segments each of which consists of a body with a scraping face, which scraping face breasts against the conveyor belt where the scraping device comprises a number of segments and the scraping face on each of the segments is individually elastically connected to the supporting structure and all the segments are covered by a flexible material, wherein the scraping device is mounted in a holder where the scraping device is provided one or more adjusting devices which push different parts of the scraping device along the direction of movement of the conveyor belt to bend the scraping device in a curve across the width of the conveyor belt.
