Abstract
A belt type variable chamber round baler includes a starting chamber for receiving crop material at the outset of bale formation. An adjustment mechanism is provided for adjusting the volume of the bale starting chamber, for accommodating baling of various crops. A series of starting chamber rollers are supported between a pair of arms, which are pivotably mounted to the baler. The adjustment mechanism is operable to control the position of the pair of arms prior to bale formation, and thereby the position of the starting chamber rollers within the bale forming chamber of the baler. In this manner, the size of the starting chamber can be adjusted.
Claims15
A round baler for forming round bales of crop material, comprising:
- a plurality of side-by-side trained around a plurality of rollers and cooperating to define a bale-forming chamber, the belts being movable between a starting position and a finish position, with the belts being trained around a forward baler roller and a rear baler roller which define a crop inlet to the bale-forming chamber;
- a mechanism for supporting the belts above and between the pair of rollers defining a crop inlet to the bale-forming chamber to define a bale starting chamber therebelow when the belts are in their starting position, comprising a pair of arms to which at least one roller is mounted, wherein each of the side-by-side belts is trained about the at least one roller between the forward baler roller and the rear baler roller and is solely supported by the at least one roller therebetween, and wherein each of the side-by-side belts defines a first run extending between the rear baler roller and the at least one roller and a second run extending between the forward baler roller and the at least one roller, and wherein the bale starting chamber is defined by the first and second runs of the side-by-side belts;
- and
- adjustment means for varying the position of the at least one roller prior to the bale formation, to vary the volume of the bale starting chamber.
In a belt-type round baler for forming round bales of crop material and including a plurality of stationary baler rollers and a plurality of side-by-side baler belts engaged with the baler rollers and cooperating to define a bale forming chamber, in which the belts are disposed in a starting position prior to bale formation and in a finish position after bale formation, the improvement comprising a mechanism for supporting the belts in the starting position to define a bale starting chamber for receiving crop material from the crop inlet of the baler at the outset of bale formation, wherein the starting chamber is located between a rear stationary baler roller and a forward stationary baler roller which define the crop inlet, comprising:
- a pair of supporting arms movably mounted to the baler above the pair of stationary baler rollers;
- and
- at least one support roller rotatably mounted to the supporting arms, wherein the belts are wrapped around the at least one support roller between the rear and forward stationary baler rollers and are solely supported thereby between the rear and forward stationary baler rollers defining the crop inlet without support by the stationary baler rollers between the rear and forward stationary baler rollers.
In a belt type round baler for forming round bales of crop material and including a plurality of stationary baler rollers and a plurality of side-by-side baler belts engaged with the baler rollers and cooperating to define a bale forming chamber, in which the belts are disposed in a starting position prior to bale formation and in a finish position after bale formation, the improvement comprising a mechanism for supporting the belts in the starting position to define a bale starting chamber for receiving crop material at the outset of bale formation, wherein the starting chamber is located between a rear lower stationary baler roller and a forward lower stationary baler roller defining the crop inlet of the baler, comprising:
- supporting structure movably mounted to the baler;
- a plurality of starting chamber rollers rotatably mounted to the supporting structure, wherein the belts are wrapped around the starting chamber rollers and are solely supported thereby between the rear lower baler roller and the forward lower baler roller defining the crop inlet without support by the stationary baler rollers between the rear and forward stationary rollers;
- and
- adjustment means for moving the supporting structure to a selected position for adjusting the position of the starting chamber rollers prior to bale formation, for varying the volume of the bale starting chamber.
A round baler for forming round bales of crop material, comprising:
- a plurality of side-by-side belts trained around a plurality of rollers and defining a bale-forming chamber, the belts being movable between a starting position and a finish position, with the belts being trained around a pair of rollers defining the crop inlet to the bale-forming chamber;
- a mechanism for supporting the belts above and between the pair of rollers defining the crop inlet to the bale-forming chamber to define a bale starting chamber therebelow;
- and
- an adjustment mechanism for varying the position of the belt-supporting mechanism prior to bale formation, to vary the volume of the bale starting chamber, wherein the adjustment mechanism is interconnected with the belt supporting mechanism to provide adjustment of the bale-supporting mechanism between an uppermost starting position and a lowermost starting position, and wherein the adjustment mechanism provides infinitely variable positioning of the bale-supporting mechanism between the uppermost starting position and the lowermost starting position.
