Bale Eject Linkage and Methods of Use

摘要

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 a pair of parallel arms that extend transversely from the sidewalls of a bale chamber a set of distinct pivot points. When activated by the operator of the bale ejection system, the a pairs of parallel arms raise simultaneously to expose an outlet through which the bale may be ejected. A formed bale may become ejected by one or more conveyer belts that exert a rearward force on the bale within the bale chamber.

主权项

1. An agricultural harvester comprising:
a bale chamber comprising a first sidewall and a second sidewall; an outlet at the rear of the bale chamber; a take-up arm positioned at the top of the baler; at least a first serpentine system arranged for the bale chamber, the first serpentine system comprising:
a plurality of baling belt rollers in operable contact with one or more baling belts, the plurality of baling belt rollers comprising at least one baling belt roller in operable contact with the take-up arm, wherein the at least one baling belt roller movable in a direction defined by a pivoting movement of the take-up arm, independent of movement of any other baling belt rollers in the baler; and a belt guide assembly, the belt guide assembly movable among a closed position and one or more open positions, comprising:
a first pair of arms extending transversely from and affixed to a first pair of pivot points on the first and second sidewalls;one or more fixed members positioned at a distance defined by the length of the first pair of arms; andat least one roller rotatably mounted upon an axis transverse to the one or more fixed members. wherein the belt guide assembly uncovers the outlet through which the bale becomes ejected from the bale chamber when the belt guide assembly is raised upward into a partially open or fully open position from its closed position; and wherein the take-up arm pivots upward simultaneously or substantially simultaneously with the belt guide assembly when the belt guide assembly is raised upward into a partially open or fully open position from its closed position.
