Technical Examples
  1. A tensioner for maintaining engagement of a conveyor belt cleaner, including one or more scraper blades mounted on a rotatable support frame, with a conveyor belt. The tensioner includes a mounting member attached to the support frame for conjoint rotation therewith, a biasing member attached to the mounting member, and an actuator attached to the biasing member. Operation of the actuator stores a biasing force within the biasing member which in turn rotates the scraper blades into full-face engagement with the conveyor belt. As the scraper blades wear, the biasing member continues to rotate the blades into full-face engagement with the conveyor belt with a biasing force that changes in magnitude. The scraper blades include a blade face having an area which changes as the blades wear, in order to maintain a substantially constant contact pressure between the blades and the conveyor belt as the blades wear.
