The present invention relates to agricultural balers of the type commonly referred to as square balers that produce bales having a rectangular cross section, and, more particularly, to bale splitting systems used with square agricultural balers.
Agricultural harvesting machines, such as balers, for example, are used to consolidate and package crop material so as to facilitate the storage and handling of the crop material for later use. In the case of hay, a mower-conditioner cuts and conditions the crop material for windrow drying in the sun. In the case of straw, an agricultural combine discharges non-grain crop material from the rear of the combine defining the straw (such as wheat or oat straw, for example) which is to be picked up by the baler. The cut crop material is typically raked and dried, and a baler, such as a square baler or a round baler, for example, straddles the windrows and travels along the windrows to pick up the crop material and form it into square or round bales. More specifically, a pickup unit at the front of the baler gathers the cut and windrowed crop material from the ground and then conveys the cut crop material into a bale-forming chamber within the baler where the crop material is compacted, typically by means of a reciprocating plunger. The bale-forming chamber usually includes a device for tying bales and a discharge outlet, for example connected to a discharge chute for gently lowering bales onto the field. During normal baling operation, tied bales are ejected from the baler through action of the plunger.
Square agricultural balers are sometimes preferred because the square-shaped bales facilitate stacking, delivery, and use. During baling, however, a small square baler has a relatively small capacity because a small square baler typically only produces one small bale at a time. Farmers either need to have multiple small square balers operating at the same time in order to harvest crop material from the field efficiently or make large square bales and convert them later into bundles of small square bales. These methods are inefficient and expensive.
Described herein is an agricultural baler that can produce small square bales at a fast rate and without the added expense of multiple balers.
Described herein is a bale splitting system for agricultural balers. The bale splitting system receives a large square bale from the bale-forming chamber and splits the large bale into two small square bales before depositing the bale on the ground surface of the field.
An agricultural baler includes a bale splitting system that splits a large square bale into two small square bales. The bale splitting system includes a cutting mechanism configured to split the bale into two smaller bales. The cutting mechanism is slanted at an adjustable angle relative to the bottom wall or the top wall of the bale chamber. The position of the cutting mechanism is adjustable relative to the front wall and the rear wall of the bale chamber. The slanted configuration improves the cutting quality of the bales.
A bale splitting system with two cutting mechanisms that are slanted in the opposite directions can additionally improve the cutting quality and the shape of the bales.
The drawing figures depict one or more implementations, by way of example only, not by way of limitations. In the figures, like reference numerals refer to the same or similar elements.
The terms “forward,” “rearward,” “upward,” “downward,” “left,” and “right,” or “top” or “bottom,” when used in connection with the agricultural baler described herein and/or components thereof are usually determined with reference to the direction of forward operative travel of the towing vehicle and the height of the baler, but they should not be construed as limiting. The terms “longitudinal” and “transverse” are determined with reference to the fore-and-aft direction of the towing vehicle and the width of the baler, and are equally not to be construed as limiting.

Further details of baler 10 may be described in U.S. Pat. No. 7,975,607, which is incorporated by reference herein in its entirety and for all purposes.
In a first aspect, a bale splitting system 200 is provided for an agricultural baler 10, more particularly a large square baler or a rectangular baler, i.e., a machine for forming square or rectangular bales from agricultural crop material. In a large square baler, for example, large bales are discharged in a longitudinal discharge direction from a discharge outlet 23 (
The bale splitting system 200 receives large bales 90 before, while the bales are bound with twine 92, or after the large bales 90 are bound with twine 92, and splits them into two small square bales before discharging bales on the surface of the ground. In other words, the bale splitting system 200 cuts or splits the large bale 90 in two smaller bales before or while the large bale 90 is tied or bound with twine 92, or after the large bale 90 is tied or bound with twine 92. The bale splitting system 200 cuts the large bale 90 along a line that runs parallel to the longitudinal discharge direction (i.e., the fore-aft direction) or parallel to the bale travel axis 100.
The bale splitting system 200 according to embodiments of the present invention may be a separate structure for being added or retro-fitted into an existing agricultural baler. Alternatively, the bale splitting system 200 may be built into agricultural baler 10.

The knife 53 can be mounted to the back of the baler 10, between the forward portion 21 and the rearward portion 22 of the bale chamber 20, and downstream of the plunger 17 and the tying assembly 25 that wraps and ties twine 92 around the bale 90. For example, one side 52 of the knife 53 can be mounted (e.g., fixed) to an upper bar (similar to the bar 60 in

Turning back to
The knife blade 53a can be configured to move between the forward portion 21 (e.g., discharge outlet 23) and the rearward portion 22 of the bale chamber 20 by way of a manually operated mechanical actuator, such as a screw adjuster mechanism or the like. For example, the knife blade 53a can be connected to the upper and lower mounting bars 60 arranged on the upper side (e.g., roof) 56 and the lower side (e.g., floor) 57 of the baler 10, via screws, bolts, pins, or the like, passing through mounting holes 52a, 52b and 54a, 54b, respectively, which can be configured to mate with pairs of upper and lower openings of a plurality of longitudinally extending series of openings formed in the upper and lower mounting bars 60. Alternatively, the knife blade 53a can be configured to move between the forward portion 21 (e.g., discharge outlet 23) and the rearward portion 22 of the bale chamber 20 by way of actuator 59, which may be an electric linear actuator, a pneumatic cylinder, an electronic actuator, or a hydraulic cylinder, e.g., double acting hydraulic cylinder having a moveable piston and controlled by a hydraulic control circuit, for example. However, embodiments are not limited to this configuration, and in other embodiments, the actuator may be driven by a pulley system, an electric motor, a solenoid, etc.
The angle θ between the knife blade 53a and the upper side (e.g., roof) 56 and the lower side (e.g., floor) 57 of the bale chamber 20 can be adjusted in a similar manner. For example, adjusting the knife blade 53a forwardly or rearwardly relative to the forward portion 21 and the rearward portion 22 of the bale chamber 20 will change the angle θ between the knife blade 53a and the upper side (e.g., roof) 56 and the lower side (e.g., floor) 57 of the bale chamber 20.
The actuator 59 used for adjusting the position and the angle of the knife blade 53a can be connected to the knife blade 53a and to a controller, an actuation circuit, or to other systems of the baler 10 by a hydraulic hose or a conduit, and/or by way of electric wires, cables, a bundle of wires or cables, or a wiring harness that includes various stranded or solid wires that interconnect the actuator with various mechanical, hydraulic, or electrical components of the baler 10, for example.

According to another aspect of the present invention, and referring now specifically to
When the knives 53a, 53b are mounted, the knife blades 53a, 53b extend diagonally in a slanted or angled manner between the upper side (e.g., roof) 56 and the lower side (e.g., floor) 57 of the bale chamber 20. The knife blades 53a, 53b are arranged in a central position between the side walls 31, 32 of the baler 10 and parallel to the side walls 31, 32 of the baler 10.

The bale splitting systems 200 and 400 illustrated in the figures and described above increase the throughput of the baler and produce multiple small square bales simultaneously, unlike a conventional small baler that only produces one bale at a time, by splitting a large square bale that enters the bale-forming chamber into two small square bales with a cutting mechanism, significantly improving the baling capacity.
The bale splitting system 200 and 400 illustrated in the figures and described above can be implemented in any hay and forage agricultural vehicle that harvests a grass type crop, including but not limited to small square baler pickups or large square baler pickups, for example.
