ABSTRACT:
A controlled bale ejection mechanism for an agricultural baler is provided. The mechanism includes a bale support which is positioned below the bale when it is ejected, that catches and supports the bale. The bale support is then translated rearward by a hydraulic cylinder and guided by support rails. As the bale support and bale approach the desired location, the bale support is lowered by tilting the rail assembly downward. An articulating shoe is used to support and lower the rails. The bale support tilts as it is lowered, thereby creating a dumping action. If additional tilting is required due to geometry limitations, additional bale support tilt can be created by a weight shift of the bale support, changing the trajectory of the rail or torque induced by the bale support cylinder. The bale is set down on the ground and the ramp assembly resets to prevent the bale from rolling forward and preparing for the next cycle. Springs are used to retract the articulating shoe and lift the rails into transport position. The timing of this system is integrated into the hydraulic baler functions (primarily the discharge gate) so no additional action is required from the operator when ejecting the bale.
