Abstract

Systems, methods and apparatus are provided for scraping material from a conveyor belt. Some embodiments include primary and secondary scraper assemblies.

First claim

The invention claimed is:

1. A conveyor scraper, comprising:
a pole;
a tension-adjustable primary scraper blade assembly supported on said pole, said primary scraper blade assembly comprising a first spring element; and
a tension-adjustable secondary scraper blade assembly, said secondary scraper blade assembly comprising a second spring element separate from said first spring element.

2. The conveyor scraper of claim 1 , further comprising:
first and second arm mounts supported on said pole independently of said primary scraper blade assembly, wherein said tension-adjustable secondary scraper blade assembly is supported on said first and second arm mounts, wherein an angular position of said secondary scraper blade assembly is adjustable.

3. The conveyor scraper of claim 2 , wherein at least one of said arm mounts comprises a fastener configured to adjust said angular position of said secondary scraper blade assembly.

4. The conveyor scraper of claim 1 , first spring element comprises a torsion spring arranged around said pole, wherein said primary scraper blade assembly further comprises:
a housing at least partially enclosing said torsion spring within said housing; and
a blade supported on said housing.

5. The conveyor scraper of claim 4 , wherein said housing comprises an extrusion having a transversely extending support, wherein said blade is supported on said support.

6. The conveyor scraper of claim 4 , wherein said housing comprises an extrusion having an internal stop, wherein said torsion spring is disposed to contact said internal stop.

7. The conveyor scraper of claim 4 , further comprising:
first and second bearings pivotally supporting said housing on said pole, each of said bearings being at least partially enclosed in said housing.

8. A conveyor scraper, comprising:
a pole configured to be supported on a conveyor; and
a primary scraper blade assembly, the primary scraper blade assembly comprising:
a torsion spring arranged around said pole;
a housing at least partially enclosing said torsion spring inside of said housing; and
a blade supported on said housing.

9. The conveyor scraper of claim 8 , further comprising:
first and second arm mounts disposed on said pole and mounted independently of said primary scraper blade assembly, said first and second arm mounts configured to releasably support a secondary scraper blade assembly.

10. The conveyor scraper of claim 9 , further comprising:
first and second bearings pivotally supporting said housing on said pole, each of said bearings being at least partially enclosed in said housing.

11. The conveyor scraper of claim 9 , further comprising:
first and second arm mounts disposed on said pole, said first and second arm mounts configured to releasably support said secondary scraper blade assembly.

12. The conveyor scraper of claim 11 , wherein said housing comprises an internal stop, said internal stop being configured to stop said torsion spring from rotating in at least a first direction.

13. A method of installing a conveyor scraper assembly, comprising:
supporting a pole of a primary scraper assembly on a conveyor; and
installing a secondary scraper assembly on said pole independently of the primary scraper assembly.

14. The method of claim 13 , further comprising:
resiliently contacting a conveyor belt with a blade of said secondary scraper assembly.

15. The method of claim 13 , further comprising:
adjusting a rotational position of said secondary scraper assembly.

16. The method of claim 15 , further comprising:
adjusting an attack angle of a blade of said secondary scraper assembly.

17. The method of claim 13 , further comprising:
supporting a blade of said primary scraper assembly on a housing supported on said pole; and
applying a torque to said blade with a torsion spring.

18. The method of claim 17 , further comprising:
at least partially enclosing said torsion spring inside said housing.

19. The method of claim 18 , further comprising:
rotationally supporting said housing on first and second bearings, said first and second bearings supported on said pole.

20. The method of claim 19 , further comprising:
at least partially enclosing each of said first and second bearings inside said housing.
