Abstract
A scraper blade assembly which is configured to provide a rigid material scraping edge supported on a resiliently compliant material such that the scraping edge is adapted to move in response to irregularities in an associated conveyor belt. Further, supporting structure for the resiliently compliant material is configured so as to promote an upward deformation of the resiliently compliant material when a compressive force is applied to the rigid material scraping edge to thereby form the resiliently compliant material as a supporting surface above the scraping edge when such a force is applied.
Claims22
A scraper blade assembly for a conveyor belt scraper comprising:
- an elongated blade body including a resilient backing member formed of a resilient material and defining a central longitudinal scraper blade axis, said resilient backing member including opposing sides, first and second faces extending longitudinally between said sides, and an upper surface located between said first and second faces and extending longitudinally between said sides;
- a longitudinally extending support frame attached to said elongated body and defining opposing first and second ends;
- end plates attached to said first and second ends for attaching said blade assembly to support structure such that said elongated body extends transversely of an associated conveyor belt;
- and
- said elongated body further including an elongated metal face plate attached to said first face of said resilient backing member and comprising a continuous strip of material having an upper edge adjacent said upper surface extending from said first end to said second end of said support frame.

- a longitudinally extending support frame attached to said elongated body for supporting said elongated body extending transversely of an associated conveyor belt;
- said resilient backing member including an upper portion extending upwardly from an upper edge of said support frame;
- said elongated body further including an elongated rigid face plate attached to said first face of said resilient backing member at said upper portion and having an upper edge for scraping material from an associate conveyor belt, said upper surface of said resilient backing member being coextensive with said upper edge of said face plate for providing support to the conveyor belt;
- said rigid face plate comprising a continuous rigid structure supported out of contact with said support structure, and extending the entire length of said elongated blade body for extending substantially the entire width of an associated conveyor belt;
- a rigid backing member extending upwardly from said upper edge of said support frame along a substantial portion of said second face of said resilient backing member for supporting said upper portion of said resilient backing member against movement when a force is applied against said rigid face plate.
