Definitions

  • the present invention relates generally to agricultural machinery and methods therefor for harvesting crop material such as hay, straw, grass and the like, and, more particularly, relates to an agricultural bale accumulator and method therefor.
  • a continuing trend to achieve an efficient farming operation and to decrease manual labor provides the need for efficient and capable agricultural machinery.
  • One type of agricultural machinery is used to harvest crop material such as hay, straw, grass and the like.
  • baler An agricultural baler
  • the baler may comprise a motorized machine driven by an operator or, alternatively, may comprise a wheeled frame adapted for traveling alongside or behind a tractor.
  • a baler is a wheeled chassis adapted for hitched connection to a tractor to be towed in tandem behind the tractor.
  • a cord such as wire or twine, is tied around the bale to hold the bale together in its compressed form.
  • the baler ejects the tied bales periodically from a bale chamber of a baler as the baler travels over the ground.
  • Each ejected bale may be directly discharged either to a bale accumulator or to the ground for later pick up by a bale collector in order to make the harvesting of the crop material more efficient and to decrease manual labor.
  • Bales provided by either the bale accumulator or the bale collector may then be deposited on a vehicle, such as a tractor trailer, for hauling to another location for storage.
  • a bale accumulator is a widely used piece of mobile equipment which may comprise a part of a baler or, alternatively, may comprise a wheeled chassis adapted for traveling alongside or behind a baler.
  • a bale accumulator is a wheeled chassis adapted for hitched connection to a baler to be towed in tandem behind the baler.
  • Examples of conventional bale accumulators are disclosed in U.S. Patent Nos. 3,272,352, 4,310,275, 4,215,964 and 4,961,679.
  • a bale accumulator is normally arranged to receive a plurality of successive bales as they eject from the bale chamber of the baler and to accumulate the received bales into a group or parcel of accumulated bales for temporary storage. The group of accumulated bales may then be discharged onto the ground in an ordered array permitting mechanical recovery thereof or, otherwise, be mechanically removed from the bale accumulator.
  • a bale collector is a widely used piece of mobile equipment which may comprise a motorized machine driven by an operator or, alternatively, may comprise a wheeled chassis adapted for traveling alongside or behind a tractor.
  • a bale collector is a motorized machine driven by an operator.
  • the bale collector is normally arranged to pick up individual bales from the ground and to accumulate the retrieved bales into a group or parcel of collected for temporary storage. The group of collected bales may then be discharged onto the ground in an ordered array permitting mechanical recovery thereof or, otherwise, be mechanically removed from the bale collector.
  • bale accumulator and "bale collector” are sometimes referred to interchangeably in the agricultural industry, the present invention generally refers to both pieces of equipment as a bale accumulator in the sense that both pieces of equipment receive and store bales. Therefore, it is contemplated that the present invention may be used on a bale collector as well as the bale accumulator, as described hereinabove.
  • balers vary in size and shape according to the type of baler used to form the bales.
  • the types of balers generally include rectangular balers and round balers. Some rectangular balers form so-called small-sized bales measuring about 36 cm x 46 cm x 31 cm to 132 cm and weighing 18 kg to 27 kg. Other rectangular balers form so-called medium-sized bales measuring about 80 cm x 87 cm x up to 249 cm and weighing 300 to 600 kg. An example of a rectangular baler forming medium-sized bales is disclosed in U.S. Patent No. 4,525,991. Still other rectangular balers form so-called large-sized bales measuring about 118 cm x 127 x up to 274 cm and weighing up to 1000 kg.
  • balers forming large-sized bales are disclosed in U.S. Patent Nos. 4,034,543 and 4,307,528. Some round balers form so-called cylindrical- sized bales measuring about 1.75 m in diameter x 1.75 m long and weighing 450 kg to 675 kg.
  • bale accumulator of the present invention is particularly well-suited for use in conjunction with rectangular balers producing the medium-sized bales.
  • principles of the present invention are not limited to bale accumulators for rectangular balers producing medium-sized bales.
  • the present invention may be utilized with great effectiveness in conjunction with rectangular balers producing the large-sized bales, rectangular balers producing the small-sized bales as well as round balers producing the cylindrical-sized bales.
  • U.S. Patent Nos. 4,961,679 and 4,955,774 each disclose an agricultural bale accumulator having a bale-transfer and bale-turning mechanism attached to one side of a chassis and an extension table pivotally attached to an opposite side of the chassis.
  • the extension table is moveable between a horizontal bale accumulating position and a vertical transport position.
  • the extension table can accommodate one bale when located in the horizontal operative position.
  • an additional castor wheel is provided on a main axle supporting the chassis in order to accommodate the extra load that can be accumulated on the extension table. Bales received on one side of the load bed are turned 90 degrees and transferred across the load bed.
  • the bales are discharged using a bale-discharge conveyor which pushes the bales accumulated on the load bed off the load bed to the ground.
  • U.S. Patent Nos. 4,961,679 and 4,955,774 do not disclose a support system which contacts the extension table at a location beyond a side of a chassis to which the extension table is attached. Therefore, the extension table does not have any direct support for a bale accumulated thereon from either the chassis or the ground. A lack of direct support for the extension table places all the stress due to the weight of a bale on the hinge which may weaken or break over time under normally rigorous field conditions. These patents also do not disclose attaching the extension table to the main bale-receiving table.
  • the center table receives large-sized bales from a bale chamber of a baler.
  • a push bar pushes a bale on the center table to the right or left table.
  • the right and left tables are provided with associated extensions which appear to have a width dimension approximately equal to one third a width dimension of each of the right and left tables.
  • a hinge connects each extension to its associated table so that it may be moved between a transport and storage position on a top surface of its associated table and an unfolded position coplanar with its associated table. When an extension is in its transport and storage position, a sensor is actuated to give a false indication that a bale in on its associated table.
  • the sensor provides a control signal to the push bar to prevent movement of the push bar toward that table thereby preventing damage to the push bar that would result if a bale were moved onto a table whose extension is folded to the transport and storage position.
  • the right and left tables are pivotally mounted on their frames between a bale accumulating position and a bale discharging position so that when the tables are unlatched they tilt downwardly at the rear of the tables under the weight of the bale to permit a bale carried thereon to slide to the ground as the bale accumulator continues its forward movement.
  • a spring pulls the table back to its latched position.
  • U.S. Patent No. 4,844,675 does not disclose a purpose for the extensions when unfolded to a position coplanar with the associated tables. Since the extensions appear to have a width dimension approximately equal to one third a width dimension of each of the right and left tables, it is clear that each of the extensions cannot accumulate an additional large bale.
  • This patent also does not disclose a support system which contacts the extension at a location beyond the side of the table to which the extension is attached. Therefore, the extension does not have any direct support for a partial bale which may be accumulated thereon from either a main frame or the ground. A lack of direct support for the extension places all the stress due to the weight of a partial bale on the hinge which may weaken or break over time under normally rigorous field conditions.
  • this patent does not teach or suggest a need for supporting the extension, at a location beyond the side of the table to which the extension is attached, when the extension is in the unstowed position and when the table is in the bale accumulating position and/or the bale discharging position.
  • Hoelscher, Inc. located at 312 S. Main, P.O Box 195, Bushton, Kansas, U.S.A.,
  • bale accumulator Model 1030 having a load bed pivotally mounted to a main frame.
  • the load bed includes a center table and two side tables on opposite sides of the center table.
  • the bale accumulator bale has a carrying capacity of three total bales on each of the three tables and a bale dumping capacity of two of the three total bales from the two side tables.
  • the center table continuously receives bales from a bale chamber of a baler during while baling and is not permitted to dump any bales.
  • the two side tables dump the two bales by pivoting about a pivot axis between a bale accumulating position and a bale discharging position, wherein the two side tables are in a horizontal position and an inclined position, respectively, relative to the main frame.
  • Holescher's bale accumulator Model 1030 is limited to a bale accumulation capacity of three bales and to a bale discharge capacity of two bales.
  • Holescher's bale accumulator does not have an extension table connected to a load bed and moveable relative to the load bed between a stowed position and an unstowed position, wherein the extension table is substantially co-planar with the load bed and adjacent to the side of the load bed when the extension table is in the unstowed position to permit the extension table to accumulate thereon an additional bale. Therefore, Holescher's bale accumulator Model 1030 cannot accumulate more than three bales.
  • bale accumulator Model 8576 having a load bed pivotally mounted to a main frame.
  • the load bed includes a center table and two side tables on opposite sides of the center table.
  • the two side tables each have an extension table pivotally attached a longitudinal side thereof and moveable between a stowed, road transport position and an unstowed, bale accumulating position
  • the bale accumulator Model 8576 has a bale has a carrying capacity of five total bales on each of the three tables and the two extension tables and a bale dumping capacity of four of the five total bales from the two side tables and the two extension tables.
  • the center table continuously receives bales from a bale chamber of a baler during while baling and is not permitted to dump any bales.
  • the two side tables and the two extension tables dump the two bales by pivoting, about a pivot axis mounted on the main frame, from a bale accumulating position to a bale discharging position, wherein the two side tables are in a horizontal position and an inclined position, respectively, relative to the main frame.
  • Case IH Corporation's bale accumulator Model 8576 does not disclose a support system which contacts the extension table, at a location beyond the side of the load bed to which the extension table is attached, when the extension table is in the unstowed position and when the load bed is in the bale accumulating position and/or the bale discharging position. Therefore, the extension table does not have any direct support for a bale which may be accumulated thereon from either a main frame or the ground. A lack of direct support for the extension table places all the stress due to the weight of a bale on a hinge which may weaken or break over time under normally rigorous field conditions.
  • U.S. Patent Nos. 4,961,679, 4,955,774 and 4,844,675 and Case IH Corporation's bale accumulator Model 8576 each teach only one extension table pivotally attached to one side of the chassis, load bed and load bed, respectively. These references do not teach or suggest attaching additional extension tables to the one extension table or supporting the one extension table in combination with any additional extension tables. Further, each of these references only teach a hinged connection between the extension table and the load bed. Various bale stacking mechanisms for accumulators are known as provided in the following disclosures.
  • U.S. Patents 4,363,583 and 4,952,111 disclose a mechanical arm that picks up and move over to the accumulator's load bed to form a stack of bales.
  • U.S. Patents 3,446,369, 3,414,139, 3,487,955, 3,918,595, 5,405,229 and 4,203,695 each disclose a bale stacking mechanism implemented as a separate loading table pivotally connected to a side of the accumulator's load bed between a horizontal bale receiving position for receiving bales a horizontal plane and a vertical bale delivery position for delivering the horizontally received bales in a vertical stacked arrangement on the load bed.
  • This type of stacking mechanism is disadvantageous because the separate loading table is offset from the bale chute of the baler takes up extra space and cannot accumulate bales for discharging.
  • Patents Re 25,750, 3,278,049, and 3,251,485 each disclose a bale stacking mechanism implemented as a separate loading platform located in front of the accumulator's load bed where stacks of bales are formed prior to being moved onto the accumulator's main load bed which accumulates and discharges the bales.
  • This type of stacking mechanism is disadvantageous because the platform performs a dedicated stacking task and cannot accumulate bales for discharging.
  • Patent 4,370,796 discloses a bale stacking mechanism implemented as a by receiving a row of bales across a lateral axis of the accumulator's load bed, then lifting the first row, then receiving a second row of bales below the first row, then stacking the first and second rows before pushing the stack across a longitudinal axis of the load bed.
  • This type of stacking mechanism is disadvantageous because the mechanism receives the bales along the lateral axis of the load bed.
  • Quadrant 1100 which forms a stack of two bales by dropping a first bale below a bale receiving position, then receiving a second bale on top of the first bale and then discharges the only two bales to the ground by dropping the bottom out from under the first bale received.
  • This type of stacking mechanism is disadvantageous because accumulator can only accumulate two bales in a stack and only two bale for the entire accumulator.
  • U.S. Patent No. 4,312,245 discloses a bale accumulator having a center, a right and a left table. A push bar pushes a bale on the center table to the right or left table. Each table has an associated switch which senses the position of a bale on that table. By monitoring the switches, the bale accumulator automatically forms a load on the tables yet permits the operator to be the sole judge of when the accumulated load of bales is to be dumped. However, the accumulator always forms the same arranged load on the accumulator.
  • U.S. Patent No. 4,844,675 discloses a bale accumulator having a center, a right and a left table.
  • a push bar pushes a bale on the center table to the right or left table.
  • a microprocessor-based control circuit determines a status of the position of the bales on the tables and displays the status on an operator's panel.
  • the control circuit monitors bale switches actuated by the presence of bales on the tables, two switches indicating the position of the push bar, and three table switches indicating when individual one of three of the bales are latched or released for dumping bales therefrom.
  • An operator's panel provides a visual display of the status of the bale accumulator and includes switches which may be actuated by the operator.
  • the control circuit controls the push bar to move bales from the center table onto the left or right table at the sides of the center table, or inhibits movement of the push bar so that a succeeding bale ejected from the baler pushes a bale on the center table onto a trailing fourth table.
  • the control circuit determines which tables should be unlatched to dump a bale therefrom, and energizes a motor or motors to unlatch the tables as determined by the control circuit.
  • Two mechanisms are generally used to discharge bales from a load bed of a bale accumulator.
  • One mechanism employs a load bed pivotable relative to a chassis of the bale accumulator. When the load bed assumes an inclined position the bales slide off the end of bale accumulator to the ground under the force of gravity as the bale accumulator advances.
  • the load bed may assume the inclined position either by exerting a force on the load bed or by permitting the weight of the bales to pivot the load bed.
  • bales may be scatterd or disoriented upon discharge.
  • a complex and costly chain and drive mechanism tends to accumulate litter requiring careful maintenance, and necessitating significant driving energy is required.
  • the accumulation of big bales provides certain problems because of the size and considerable weight of the bales.
  • bales are "dropped" from the baler onto a receiving station of the accumulator
  • size and weight of big bales does not permit such delivery methods.
  • Another problem with the collating of big bales is that they are delivered continuously from the baler. One bale is juxtaposed to the next and careless separation of a bale which has just been formed from one that is still being formed in the baler can cause damage, not only to the bale but may affect operation of the baler itself.
  • U.S. Patent 4,312,245 discloses a bale accumulator having a chassis and a bale receiving bed comprising a central part and two side parts. A bale is received from the baler on the central part and may be moved to either one side part of the other side part. The two side parts are moveable to a bale delivering position to deliver the bales stored thereon to the ground. Although the bale accumulator is large enough to support three bales, it cannot deliver an array of three bales to the ground since the central part has to remain fixed to receive bales from the baler.
  • 4,215,964 shows a bale accumulator for use in conjunction with a so- called large rectangular baler having a generally centrally disposed bale case as seen in traverse direction of the machine.
  • the bale accumulator in operation, is coupled to the rear of the baler with a central bale receiving table generally aligned with the bale case and with bale holding platforms at both sides of the bale receiving table.
  • Bale transfer means are associated with the receiving table and are operable successively to transfer one bale from the receiving table to one bale from the receiving table to one side platform and a next bale from the receing table to the opposite side platform.
