A square baler with an ejector system

摘要

A square baler having a bale case within which crop is compacted by means of a plunger and a discharge outlet at one end of the bale case is provided and an auxiliary ejector system for advancing bales towards the discharge outlet independently of the movement of the compacting plunger. The ejector system comprises a shuttle assembly (10) mounted in a wall of the bale case for reciprocation parallel to the direction of movement of the bales in the bale case. A least one dog (102) mounted on the shuttle assembly (10) engages in the last bale in the bale case positioned nearest the discharge outlet and advances the bale incrementally out of the discharge outlet in response to reciprocation of the shuttle assembly (10). In the invention, a second shuttle assembly (12) is mounted in a wall of the bale case for reciprocation independently of the first shuttle assembly (10). The second shuttle assembly (12) has at least one dog (122) to engage in the next-to-last bale in the bale case. By selecting which of the shuttle assemblies to activate, an operator may elect to eject only the last base in the bale case or the last two bales.
