Abstract
An agricultural baler includes a main bale chamber extending in a bale forming direction from an inlet end to an outlet end. The main bale chamber includes a plurality of stationary walls and a plurality of movable density doors positioned downstream from the stationary walls, relative to the bale forming direction. The stationary walls include a ceiling, a first side wall and a second side wall. A plunger compresses and moves the crop material from the inlet end towards the outlet end of the bale chamber. The baler is characterized in that the first side wall, the second side wall and/or the ceiling comprises a constriction surface, which constricts the main bale chamber in a direction transverse to the bale forming direction.
Claims20
An agricultural baler, comprising:
- a main bale chamber extending in a bale forming direction from an inlet end to an outlet end, the main bale chamber including a plurality of stationary walls and a plurality of movable density doors positioned downstream from the stationary walls, relative to the bale forming direction, the stationary walls including a ceiling, a first side wall and a second side wall, the plurality of density doors comprise a top door positioned downstream and adjacent to the ceiling, a first side door positioned downstream and adjacent to the first side wall, and a second side door positioned downstream and adjacent to the second side wall;
- and
- a plunger for compressing and moving the crop material from the inlet end towards the outlet end of the bale chamber, the plunger moves between a retracted position and an extended position, at least one of the first side wall, the second side wall and the ceiling having a constriction surface, the constriction surface having an upstream end located immediately downstream from the extended position of the plunger and a downstream end located downstream of the upstream end and immediately preceding the plurality of movable density doors relative to the bale forming direction, the top door, the first side door, and the second side door each having an inwardly angled surface relative to the bale forming direction such that the constriction surface and the angled surfaces constrict the main bale chamber in a direction transverse to the bale forming direction.
