Abstract:

A scraper assembly for a baler includes a mounting plate attached to a face of a plunger. The mounting plate includes an annular countersunk region and a concentric mounting bore. A follower plate includes an annular aperture. A scraper plate is attached to the follower plate for scraping a wall of a compression chamber. A cam insert includes a first annular projection seated within the annular aperture of the follower plate, and a second annular projection seated within the annular countersunk region of the mounting plate. The cam insert further includes a through bore extending through the second annular projection. The second annular projection and the through bore are eccentric from a center of the annular aperture and the first annular projection. A threaded fastener extends through the through bore of the cam insert and into threaded engagement with the mounting bore in the mounting plate.
