Abstract: The present invention relates to a baler ejection system that may be used with an agricultural harvester, such as a round baler, waste baler, combine, or cotton harvester. More particularly, the bale ejection system uses the motion of two pairs of parallel arms that extend transversely from the sidewalls of a bale chamber at two sets of distinct pivot points. When activated by the operator of the bale ejection system, the two pairs of parallel arms raise simultaneously to expose an outlet through which the bale may be ejected. The bale ejection system is designed to allow a larger outlet for the bale evacuation as compared to existing bale ejection systems that employ circular motion to expose the bale outlet. A formed bale may become ejected by one or more conveyer belts that exert a rearward force on the bale within the bale chamber. The bale becomes ejected through the outlet onto a field upon which the bale ejection system is operating or into a second bale chamber.

The offsetting rolls are aligned on axes that are parallel to the normal guide roll axes and arranged so that one offsetting roll is positioned generally forward of the other. One or more belts are directed around the forward offset roll while the remainder of the belts is directed around the rearward offsetting roll. The alignment and separation of the offsetting rolls is configured to allow roll belts of equal lengths to be used regardless of routing around the offsetting rolls. Trash removal may be improved by the addition of an auger in the space between the offset belts to urge the trash laterally, generally along the length of the offsetting rolls.

Abstract: A roll mounting apparatus for the lower bale forming roll of a round baler enabling the roll to be selectively installed in one of two positions using common mounting components. The normal roll mounting aperture in the side wall allowing the roll shaft ends to extend therethrough is elongated to permit limited radial movement of the shaft. A reversible adapter connected to the main frame (one on each main frame side wall) at each end of the shaft covers a portion of the elongated aperture and provides a mounting connector (threaded hole) to replace a fastener receptacle eliminated by elongation of the aperture. By repositioning the adapter, the shaft may be displaced radially to one of two positions, thereby allowing the roll to be installed in an optimum location for the crop material or to enable manufacturing flexibility. The roll can easily be relocated to the other position, as necessary, using bolted connections securing the adapter to the side walls and the roll shaft bearing to the frame and adapter.
