Abstract

A flexible scraper for a grader or other solid object processing system. The flexible scraper is adjustably mounted to a frame and contacts a rotating roller to clean the rotating roller or prevent components from wrapping around the roller, as well as maintain products within designated lanes. Connectors allow insertion and release of the scraper into and from the frame. The flexible scraper is inserted into slots in the frame and held against the rotating roller by gravity.

First claim

What is claimed is:

1. A processor for processing solid objects, comprising:
a frame;
a plurality of rollers extending in a longitudinal direction mounted to the frame;
a plurality of receptacles hanging at a first end of the plurality of rollers above the rollers, each receptacle including a slot with an open top;
a plurality of scrapers mounted to the frame, each scraper comprising a longitudinally extending base receiving a flexible blade that hangs down and contacts an associated roller, the base having a first mounting tab at a first end of the base, the first mounting tab including a connector extending in the longitudinal direction that is received in a slot of a corresponding receptacle, so that the position of each scraper is adjustable relative to the frame.

2. The processor of claim 1 , wherein the connector comprises a neck and a head.

3. The processor of claim 1 , wherein the head is round and each slot is tapered and has a rounded bottom.

4. The processor of claim 1 , further comprising an adjustment mechanism connected to the frame for adjusting the position of the rollers, wherein the receptacles are connected to the adjustment mechanism for adjusting the position of the rollers.

5. The processor of claim 1 , wherein the rollers rotate about a longitudinal axis, and each blade contacts an upward rolling portion of an associated roller.

6. A method of assembling a processor for processing solid objects, comprising:
providing a processor having a plurality of longitudinally extending rollers mounted to a frame;
providing a scraper having a connector and a flexible blade; and
inserting the connector of the scraper through an open top into a tapering slot in the frame so that the flexible blade contacts a roller of the processor.

7. The method of claim 6 , further comprising the step of adjusting the position of the scraper relative to the frame.

8. A processor for processing solid objects, comprising:
a frame;
a plurality of rollers extending in a longitudinal direction mounted to the frame;
a plurality of receptacles hanging at a first end of the plurality of rollers, each receptacle including a slot;
a plurality of scrapers mounted to the frame, each scraper comprising a longitudinally-extending base receiving a flexible blade and having a first mounting tab at a first end of the base, the first mounting tab comprises a first leg, a second leg extending at an obtuse angle relative to the first leg and a connector extending from the second leg for insertion in a corresponding slot to mount the scraper to the frame.

9. The processor of claim 8 , further comprising a second mounting tab connected to the second end of the base and a second connector extending from the second mounting tab.

10. The processor of claim 8 , wherein the second leg is substantially horizontal when the scraper is mounted to the frame.

11. The processor of claim 8 , wherein each connector extends substantially perpendicular from the second leg in a longitudinally outward direction and comprises a neck and a head.
