Abstract
The present invention provides a scraper mechanism for a disk blade including a wear ring attached to the rim of a rotary scraper and releasably biased toward and held in planar contact with one side of a disk blade. The wear ring is molded from a low friction, long-wearing material, such as molded nylon. The low friction material eliminates the metal to metal contact of conventional rotary scrapers and therefore eliminates the squeal associated with rotary scrapers. Also, wear of the scraper is audibly detected when the wear ring is worn away, thereby alerting the operator that maintenance is required.
Claims22
In a scraper mechanism for a disk blade including means for supporting the scraper with respect to the disk blade, said scraper including a hub, a plurality of spokes extending radially from the hub, and a peripheral rim supported by the spokes, the improvement comprising:
- a wear ring releasably secured in contacting relationship with said rim, and disposed intermediate said rim and said disk blade, said wear ring being held in planar contact with one side of said disk blade.
In a rotary scraper mechanism for a disk blade including a plurality of spokes extending from a hub, and means for biasing the spokes toward the disk blade, the improvement comprising:
- a wear ring releasably secured in contacting relationship with said spokes, and disposed intermediate said spokes and said disk blade, said wear ring being held in planar contact with one side of said disk blade by said biasing means.
