Abstract

A compression roll housing for an agricultural machine, having a side panel provided with at least one elongated aperture for receiving a shaft of a compression roll and allowing movement of the shaft within the aperture. The housing is provided with a cover plate which rotates about an axis parallel to the shaft and is provided with an indentation to partially surround the shaft. Movement of the shaft, such as along a longitudinal axis of the aperture, causes the plate to rotate to provide a cover across the aperture to prevent the escape of any material from the housing.

Claims

1. A compression roll housing for an agricultural machine, said housing having a side panel provided with at least one elongated aperture for receiving a shaft of a compression roll, said aperture allowing movement of the shaft along the elongated aperture, wherein the housing is provided with a cover plate which rotates about an axis parallel to the shaft, and said plate is provided with an elongated indentation to partially surround the shaft, and wherein movement of the shaft along the elongated aperture causes movement of the shaft along the elongated indentation thereby causing the plate to rotate to provide a cover across the elongated aperture to prevent the escape of material from the housing.

2. The compression roll housing as claimed in claim 1 wherein the aperture allows movement of the shaft along a longitudinal axis of the aperture, which movement causes the plate to rotate to provide a cover across the aperture in all positions of the shaft within the aperture.

3. The compression roll housing as claimed in claim 1 wherein the plate has the form of a sector of a circle.

4. The compression roll housing as claimed in claim 1 wherein the cover plate is positioned on the side panel inside of the housing.

5. The compression roll housing as claimed in claim 2 wherein the plate has the form of a sector of a circle.

6. The compression roll housing as claimed in claim 3 wherein the cover plate is positioned on the side panel inside of the housing.
