ABSTRACT:
A scraper blade is provided for a conveyor belt for removing material such as hot asphalt mix which would otherwise tend to stick to the conveyor belt surface. A scraper blade assembly is mounted to a swinging arm which is pivoted to the conveyor frame and positioned near the underside of the discharge end of the conveyor. A blade is mounted transversely to the conveyor belt for scraping material from its surface, and heating elements are provided for heating the blade to prevent material build-up on the scraper. A control system including sensors, a control valve and a control cylinder is provided for pivoting the blade away from the conveyor to allow passage of the conveyor splice without damaging it, or in response to a conveyor belt stoppage.
