Reversing mechanism and conveying means and agricultural baler provided therewith

Reversing mechanism for a crop conveying mechanism of an agricultural baler, the conveying mechanism comprising a feeder duct provided to receive cut crop material prior to a bale forming chamber by a stuffer of the conveying mechanism and a first feeding mechanism provided for conveying cut crop material in the feeder duct by conveying elements mounted around an axis of the of the first feeding mechanism such that the conveying elements can rotate in a working direction, the reversing mechanism comprising:

• a ratchet configured for mounting to the axis such that the ratchet rotates together with the conveying elements and a pawl carried by a reverser of the reversing mechanism, the pawl being configured to engage the ratchet upon reciprocation of the reverser such that the conveying elements rotate in a direction opposing the working direction,
• a driving pulley mounted for rotation together with the conveying elements and configured for connection about the axis such that the axis and the conveying elements are configured for rotation in the working direction by a driving belt engaging the driving pulley, and
• a tensioning pulley provided for controlling the tension of the driving belt, such that by engaging the driving belt, the driving belt engages the driving pulley such that the axis is rotationally driven by the driving belt, and by releasing the driving belt by reciprocating the reverser the tensioning pulley is moved such that the driving belt no longer engages the driving pulley and the axis is no longer rotationally driven by the driving belt;
• wherein the reverser is adapted for tilting the tensioning pulley away from the driving belt by pushing onto a lever connected to the tensioning pulley, the reverser having a surface along and over which a portion of the lever travels to thereby tilt the tensioning pulley;
• and
• wherein the ratchet and the driving pulley are mounted to the axis such that the ratchet and the driving pulley rotate together with the axis.
