Abstract
A large round baler includes bale-forming means conducted over rotary bodies with stationary axes and rotary bodies with movable axes so as to define an expansible circumference of a baling chamber. Some of the movable rotary bodies are mounted to a carrier mounted to fixed side walls defining opposite sides of the baling chamber. The carrier is pivotally mounted to opposite side walls defining opposite sides of the baling chamber for movement between a lowered operating position and a raised discharge position wherein it holds a span of the bale-forming means, which during operation, forms the rear portion of the circumference of the baling-chamber above the formed bale so that the latter may be discharged.
Claims7
In a large round baler, having chassis-supporting components forming an expansible baling chamber and including at least one endless, flexible bale-forming means, that is conducted over rotary bodies with stationary axes and rotary bodies with movable axes, and that generally surrounds the circumference of a baling chamber with said rotary bodies with stationary axes including a first rotary body with a fixed axis being located at a forward side of an inlet leading to a baling chamber having a circumference otherwise surrounded by said flexible bale-forming means, and having opposite sides defined by opposite side walls, the improvement comprising:
- a) a carrier mounted to said opposite side walls exteriorly of said baling chamber for pivoting vertically between a lowered operating position, and a raised bale discharge position;
- b) said rotary bodies with movable axes including first, second, and third rotary bodies with respective movable axes mounted to said carrier, with said first rotary body with a movable axis being positioned at a location adjacent an opposite side of said inlet from said first rotary body with a fixed axis when said carrier is in said operating position, and with said second and third rotary bodies with movable axes being mounted adjacent each other at a location spaced rearward from said first rotary body with a moveable axis and forming a slot between the last-named second and third rotary bodies;
- c) at least one tensioning mechanism including a least a fourth rotary body with movable axis;
- d) a first span of said bale-forming means extending between said first and fourth rotary bodies with movable axes and forming a rear expansible section of the circumference of said baling chamber, with its tension being determined at least in part by said at least one tensioning mechanism;
- and
- e) a second span of the bale-forming means extending rearwardly from said first rotary body with a moveable axis through said slot, whereby movement of said carrier to said bale discharge position will result in said first and second spans of said bale-forming means being elevated so as to permit a completed bale to be discharged from said baling chamber.
