Conveyor belt scraper
US D657525 S1
A scraper blade has a tip of hard material and a base of resilient material. The base has at least one concave surface on the front side adjacent to the base and may have an additional concave surface on the back side adjacent to the tip. When the blade is urged against a conveyor belt for removing material, a substantial vertical force created by a significant obstruction on the belt will compress the scraper blade and will cause the blade to deform and move away from the belt until the obstruction has passed. A scraper blade system includes the scraper blade and an adjustment block for holding and adjusting the scraper blade against the conveyor belt.
