Conveyor belt stripper for moving sticky minerals

摘要

The crossbar is fitted with scrapers (5) acting on the conveyor belt. These scrapers are automatically swivelled through entrainment by the belt jointly about the axis of the crossbar from a work position to a reversing position and vice versa as the belt running direction changes over a predetermined arc angle.The scrapers are mounted on a sleeve tube of the tubular crossbar. The sleeve tube freely rotates round the crossbar between two stops defining the arc angle.
