SUMMARY OF THE INVENTION =
The present disclosure provides an agricultural implement apparatus that overcomes problems in the prior art.
In a first embodiment the present disclosure provides an agricultural implement for mounting on a U-shaped foundation frame supported on wheels for travel over a ground surface where the foundation frame includes first and second laterally spaced mounting beams fixed to and extending from a base. The implement is configured to perform an agricultural operation, to rest on the ground surface when in an idle position, and to attach to the foundation frame when in an operating position. The implement comprises a rigid implement portion configured to be attached to the first and second mounting beams at first and second beam locations remote from the base such that the first and second mounting beams are prevented from moving laterally with respect to each other.
In a second embodiment the present disclosure provides an agricultural implement apparatus for mounting on a U-shaped foundation frame supported on wheels for travel over a ground surface where the foundation frame includes a base beam and first and second substantially parallel and laterally spaced mounting beams fixed to and extending in a like direction from corresponding first and second ends of the base beam.
The apparatus comprises an operating implement configured to perform an agricultural operation and including a rigid structural member. A support assembly is configured to support the operating implement in an idle position on the ground surface. The rigid structural member is configured to be attached to the first and second side beams at corresponding first and second beam locations remote from the base beam such that the first and second mounting beams are substantially prevented from moving laterally with respect to each other.
2 In a third embodiment the present disclosure provides an agricultural implement apparatus comprising a U-shaped foundation frame supported on wheels for travel over a ground surface where the foundation frame includes right and left substantially parallel and laterally spaced mounting beams fixed at inner ends thereof to a substantially horizontal base beam and extending in an outward direction from the base 'beam to outer ends thereof remote from the base beam such that an open implement area is provided between the mounting beams from the outer ends of the mounting beams to the base beam. An implement is configured to perform an agricultural operation, to rest on the ground surface when in an idle position, and to attach to the foundation frame in the open implement ,area when in an operating position. A plurality of beam attachment mechanisms is mounted to the foundation frame. Each beam attachment mechanism comprises a lift arm pivotally attached at an inner end thereof to the corresponding beam and defining a hook at an outer end thereof, where the lift arm is pivotal from a loading position extending in the outward direction to an operating position extending upward.
Each beam attachment mechanism further comprises a hydraulic cylinder operative to pivot the lift arm between the loading position and the operating position, and a beam engagement member. For each beam attachment mechanism, a corresponding implement attachment mechanism is mounted to the implement, each implement attachment mechanism comprising a shaft oriented substantially horizontally and an implement engagement member. The attachment mechanisms are configured such that, with the lift arms in the loading position, the foundation frame is movable to an implement loading position with respect to the implement in the idle position where the hook of each beam attachment -mechanism is located under the shaft of the corresponding implement attachment mechanism such that pivoting the lift arms to the operating position moves the implement upward and in an inward direction such that each implement engagement member moves into engagement with the corresponding beam engagement member.

3 open implement area. With no connection between the first and second mounting beams except at the base beam, there is a clear space between the mounting .beams which facilitates loading of implements that extend above the mounting beams however since the mounting beams are connected to each other only at their ends fixed to the base beam, forces exerted on the opposite outer ends thereof can put severe stresses on the connection to the base beam. Attaching the rigid structural member to outer portions of the mounting beams prevents lateral movement of one beam with respect to the such that lateral forces on the outer end of one beam are resisted by both beams.
The present disclosure further provides an agricultural implement comprising corresponding beam and implement attachment mechanisms which provides a secure mounting of the implement to the foundation frame, as well as providing a rigid implement connected to each beam such that lateral movement of one mounting beam with respect to the other is prevented. The implement also provides a simple and effective implement moving mechanism to raise the implement from the idle position supported on the ground to the operating position supported on the foundation frame.

A foundation frame 3 includes first and second laterally spaced mounting beams 9A, 9B fixed to and extending from a base, illustrated here as a base beam 11, and with no connection between the first and second mounting beams 9A, 9B except at the base beam 11. The foundation frame 3 may be self-propelled to move an implement 15 over a field to perform an agricultural operation, or may simply be a foundation platform providing a wheeled support frame to which various implements can be connected.
The apparatus 1 includes first and second beam attachment mechanisms 13A, 13B
adapted to be mounted on the corresponding first and second mounting beams 9A, 9B at beam locations remote from the base beam 11. The various beam attachment mechanisms 13 described can be attached to the beams 9 by welding or with plates and bolts and the like suitably configured.
The apparatus 1 includes an operating implement 15 configured to perform an agricultural operation. The illustrated implement 15 is a grain tank configured to receive and dispense granular material such as harvested crops, and when mounted on the foundation frame 3, to transport the granular material.
In the illustrated apparatus 1 the first and second mounting beams 9A, 9B are laterally spaced and substantially parallel and extend in a like direction from corresponding first and second ends 11A, 11B of the base beam 11. The apparatus 1 includes a rigid
7 implement portion that is configured to be attached to the mounting beams 9 by the beam attachment mechanisms 13 such that the first and second mounting beams 9A, 9B
are prevented from moving laterally with respect to each other.
In the illustrated apparatus 1 the rigid implement portion is provided by a rigid structural member 17, here the frame forming part of the operating implement 15, that is configured to be attached to the first and second beam attachment mechanisms 13A, 13B
mounted on the corresponding first and second mounting beams 9A, 9B at fixed beam locations remote from the base beam 11 such that the mounting beams 9 are substantially locked in a position that is fixed with respect to each other and with respect to the rigid structural member 17. In the illustrated apparatus 1 first and second implement attachment mechanisms 19A, 19B are mounted on the rigid structural member 19 at locations corresponding to the beam locations where the first and second beam attachment mechanisms 13, 13B have been attached.
When the foundation frame 3 is in the loading position with respect to the implement 15 =
as schematically illustrated in Fig. 3, the first and second implement attachment mechanisms 19A, 19B are directly above the corresponding first and second beam attachment mechanisms 13A, 13B. The illustrated implement 15 is configured such that when the foundation frame 3 is in the loading position as seen in Fig. 5, the implement 15 is between and above the first and second mounting beams 9A, 9B.
The apparatus 1 includes a support assembly, illustrated as hydraulic jacks -21 configured to support the operating implement 15 in an idle position on the ground surface 7 as shown in Figs. 1 ¨ 3. The apparatus 1 further includes an implement moving mechanism operative, when the foundation frame 3 is in the loading position with respect to the implement 15 as illustrated in Figs. 3 and 5, to move the implement 15 vertically upward or downward from the position of Figs. 3 and 5 to the position of Fig. 4 where the weight of the implement is transferred wholly from the ground surface 7 to the foundation frame
are prevented from moving laterally with respect to each other.
In the illustrated apparatus 1 the rigid implement portion is provided by a rigid structural member 17, here the frame forming part of the operating implement 15, that is configured to be attached to the first and second beam attachment mechanisms 13A, 13B
mounted on the corresponding first and second mounting beams 9A, 9B at fixed beam locations remote from the base beam 11 such that the mounting beams 9 are substantially locked in a position that is fixed with respect to each other and with respect to the rigid structural member 17. In the illustrated apparatus 1 first and second implement attachment mechanisms 19A, 19B are mounted on the rigid structural member 19 at locations corresponding to the beam locations where the first and second beam attachment mechanisms 13, 13B have been attached.
When the foundation frame 3 is in the loading position with respect to the implement 15 =
as schematically illustrated in Fig. 3, the first and second implement attachment mechanisms 19A, 19B are directly above the corresponding first and second beam attachment mechanisms 13A, 13B. The illustrated implement 15 is configured such that when the foundation frame 3 is in the loading position as seen in Fig. 5, the implement 15 is between and above the first and second mounting beams 9A, 9B.
The apparatus 1 includes a support assembly, illustrated as hydraulic jacks -21 configured to support the operating implement 15 in an idle position on the ground surface 7 as shown in Figs. 1 ¨ 3. The apparatus 1 further includes an implement moving mechanism operative, when the foundation frame 3 is in the loading position with respect to the implement 15 as illustrated in Figs. 3 and 5, to move the implement 15 vertically upward or downward from the position of Figs. 3 and 5 to the position of Fig. 4 where the weight of the implement is transferred wholly from the ground surface 7 to the foundation frame
8 3. In the schematically illustrated apparatus 1 the implement moving mechanism is provided by jack handles 23 that extend or retract the hydraulic jacks 21. It is contemplated that the hydraulic jacks 21 could also be connected to a hydraulic power source of the foundation frame 3 when the foundation frame 3 is in the loading position.
In the illustrated apparatus 1 the jack handles 23 are manipulated to move the implement downward such that the first implement attachment mechanism 19A bears against the first beam attachment mechanism 13a and the second implement attachment mechanism 19B bears against the second beam attachment mechanism 13B as shown in Fig. 4.
The 10 jack handles 23 are manipulated such that the weight of the implement 15 is wholly transferred from the ground surface 7 to the foundation frame 3, and then further such that the hydraulic jacks 21 move off the ground surface 7 as shown in Fig. 4.
It is contemplated as well that in some configurations of the implement, the implement 15 moving mechanism will move the implement upward so that the first implement attachment mechanism bears upward against the first beam attachment mechanism and the second implement attachment mechanism bears upward against the second beam attachment mechanism, and the two are connected together.
In the illustrated apparatus 1 the beam attachment mechanisms 13 and the implement attachment mechanisms 19 can be conveniently provided by cooperating latch mechanisms 25 as schematically illustrated in Fig. 6. The latch mechanisms 25 are provided by conical projections 27A extending upward from the top surface of the mounting beams 9 and corresponding conical recesses 27B in the rigid structural member 17. As the rigid structural member 17 moves downward the conical projection enters the conical recess 27B and further downward movement moves the conical projection 27A and recess 27B into full engagement in the correct alignment.
The implement 15 is attached to the first and second mounting beams 9 when the implement
In the illustrated apparatus 1 the jack handles 23 are manipulated to move the implement downward such that the first implement attachment mechanism 19A bears against the first beam attachment mechanism 13a and the second implement attachment mechanism 19B bears against the second beam attachment mechanism 13B as shown in Fig. 4.
The 10 jack handles 23 are manipulated such that the weight of the implement 15 is wholly transferred from the ground surface 7 to the foundation frame 3, and then further such that the hydraulic jacks 21 move off the ground surface 7 as shown in Fig. 4.
It is contemplated as well that in some configurations of the implement, the implement 15 moving mechanism will move the implement upward so that the first implement attachment mechanism bears upward against the first beam attachment mechanism and the second implement attachment mechanism bears upward against the second beam attachment mechanism, and the two are connected together.
In the illustrated apparatus 1 the beam attachment mechanisms 13 and the implement attachment mechanisms 19 can be conveniently provided by cooperating latch mechanisms 25 as schematically illustrated in Fig. 6. The latch mechanisms 25 are provided by conical projections 27A extending upward from the top surface of the mounting beams 9 and corresponding conical recesses 27B in the rigid structural member 17. As the rigid structural member 17 moves downward the conical projection enters the conical recess 27B and further downward movement moves the conical projection 27A and recess 27B into full engagement in the correct alignment.
The implement 15 is attached to the first and second mounting beams 9 when the implement
9 attachment mechanisms 19 bear against the beam attachment mechanisms 13 to engage the latch mechanisms 25.
Correct alignment of the rigid structural member 17, and thus the implement 15, with the foundation frame 3 is facilitated since the conical projection 27A can enter an edge of the conical recess 27B and will be forced into alignment as the conical projection 27A moves fully into the conical recess 27B.
Further a lock recess 31 can be provided in the conical projection 27A
:configured to receive a lock member 33 that is biased by a spring 35 or the like when the conical projection 27A and recess 27B are fully engaged. A latch release 29 is mounted on the open side of the rigid structural member 17.
The illustrated latch members 25 prevent lateral movement of one beam 9 with respect to the other however up and down movement of one mounting beam 9 with respect to the other is not significantly reduced.
Figs. 7 and 8 schematically illustrate an alternate arrangement wherein the beam attachment mechanisms 13 and the implement attachment mechanisms 19' comprise plates 37 attached to the rigid structural member 17' and to the mounting beams 9' and defining mounting holes 39. The implement via the rigid structural member 17' is attached to the mounting beams 9' by a bolt 41 through the holes 39 in the plates 37.
The implement apparatus 1 can be configured to perform a variety of agricultural operations. Fig. 9 schematically illustrates an implement 115 comprising agricultural product tanks 151 mounted to the mounting beams 109 of the foundation frame 103 by plates 137 and bolts 141. Furrow openers 153 are mounted on a laterally ex/ending implement frame 155 and the implement 115 is configured to seed a crop. =
Fig. 10 schematically illustrates an implement 215 comprising cultivator shanks 257 mounted on a laterally extending implement frame 259 and configured to cultivate a field surface.
Fig. 11 schematically illustrates an implement 315 comprising a liquid tank 361 and sprayer nozzles 363 mounted on a laterally extending sprayer boom and configured to spray liquid chemicals on a crop.
The disclosed implement apparatus 1 adds structural rigidity to a foundation frame which includes mounting beams 9 extending from a base, such as a base beam 11. With no connection between the first and second mounting beams 9A, 9B except at the base beam 11, there is a clear space between the mounting beams 9 which facilitates loading of implements that extend above the mounting beams 9, such as the grain tank 15 however since the mounting beams 9 are connected to each other only at their ends fixed to the base beam 11 forces exerted on the opposite outer ends thereof can put severe stresses on the connection to the base beam 11. By attaching the rigid structural member 17 to outer portions of the mounting beams 9, lateral movement of one beam with respect to the other is prevented and so lateral forces on the outer end of one beam 9 are resisted by both beams 9A. 9B.
It is contemplated that in the operations contemplated up and down movement of one mounting beam 9 with respect to the other will not subject the connection of the mounting beams 9 to the base beam to excessive forces.
Figs. 12 ¨ 19 illustrate an agricultural implement apparatus 101 comprising a U-shaped foundation frame 103 supported on wheels 105 for travel over a ground surface where the foundation frame 103 includes right and left substantially parallel and laterally spaced mounting beams 109R, 109L fixed at inner ends thereof to a substantially horizontal base beam 111 and extending in an outward direction OD from the base beam 111 to outer ends 110 thereof remote from the base beam 111 such that an open implement area 112 is provided between the mounting beams 109 from the outer ends 110 of the mounting beams to the base beam 111. The illustrated foundation frame 103 is self-propelled and includes a motor assembly 108 that provides hydraulic power to drive and steer the wheels 105, and provide any other implement power requirements. For clarity of illustration the motor assembly 108 is not shown in Figs. 12 and 13.
An implement is configured to perform an agricultural operation such as seeding, cultivating, spraying as described above, and only the implement frame 115 of the implement is illustrated to facilitate viewing the attachment of the implement frame to the foundation frame 103. Also as described above the implement is configured to rest on the ground surface when in an idle position, as illustrated in the top view of Fig. 12, with the foundation frame 103 approaching. The implement frame 115 is configured to attach to the foundation frame 103 in the open implement area 112 when in an operating position as shown in Figs. 13 and 19.
In the illustrated apparatus 101 four beam attachment mechanisms 114 are mounted to the foundation frame 103. Right and left outer beam attachment mechanisms 114RO, 114L0 are mounted to corresponding right and left end portions of the con-esponding right and left mounting beam s 109R, 109L, and right and left inner beam attachment mechanisms 114RI, 114LI are mounted to the base beam 111 .
Corresponding right and left outer implement attachment mechanisms 126R0, 126L0 are 'mounted to the implement 115 at locations corresponding to locations of the right and left outer beam attachment mechanisms 114R0, 114L0, and corresponding right and left inner implement attachment mechanisms 126R1, 126L1 are mounted to the implement 115 at locations corresponding to locations of the right and left inner beam attachment mechanisms 114R1, 114LI. The four connections raise the implement 115 up from the idle position in a level orientation and then hold the implement 115 securely to the foundation frame 103.
Each beam attachment mechanism 114 comprises a lift arm 116 pivotally attached at an inner end thereof to the corresponding beam about a lift pivot axis LPA
oriented . substantially horizontally and perpendicular to the outward direction OD.
The lift arms 116 define a hook 118 at the outer ends thereof and are pivotal from a loading position shown in Figs. 14 and 16 extending in the outward direction OD to an operating position extending upward as shown in Fig. 17. A hydraulic cylinder 120 is operative to pivot the lift arm 116 between the loading position and the operating position and a beam engagement member 122 is operative to engage a corresponding implement engagement member 124 attached to the implement 115.
For each beam attachment mechanism 114, a corresponding implement attachment mechanism 126 is mounted to the implement 115. Each implement attachment mechanism 126 comprises a shaft 128 oriented substantially horizontally and perpendicular to the outward direction OD, and the implement engagement member 124.
The attachment mechanisms 114, 126 are configured such that, with the lift arms 116 in the loading position, the foundation frame 103 is movable to an implement loading position with respect to the implement 115 in the idle position where the hook 118 of each beam attachment mechanism 114 is located under the shaft 128 of the Corresponding implement attachment mechanism 126. Figs. 12, 14, and 15 show the lift arm 116 in the loading position approaching the implement attachment mechanisms 126 on the implement 115, and Fig. 14 shows, in phantom lines, the lift arm 116 in the implement loading position with the hook 118 under the shaft 128.
With the foundation frame 103 in implement loading position, pivoting the lift arms 116 toward the operating position of Fig. 17 moves the implement 115 upward and in an inward direction ID. Fig. 16 shows the lifting arm 116 in an intermediate position partially raised from the loading position of Fig. 15 and the implement 115 raised from its idle position supported on the ground. When the lifting arm 116 reaches the operating position of .Fig. 17, each implement engagement member 124 moves into engagement with the corresponding beam engagement member 122 and the implement 115 is fully raised and secured in the operating position as shown in Figs. 13, 17, and 19.
Removing the implement 115 from the foundation frame 103 and returning same to the idle position supported on the ground is accomplished by activating the hydraulic cylinders 120 in the opposite direction to move the lift arms 116 from the operating position to the loading position which moves the implement 115 forward and downward to the idle position, where the foundation frame 103 and attached beam attachment mechanisms 114 can be moved away from the implement 115 and the corresponding implement attachment mechanisms 126.
In the illustrated apparatus 101 the beam engagement member 122 is provided by a pin configured to slide into the socket that forms the implement engagement member 124.
The pin comprises a tapered end 130 operative to guide the pin into the socket. The illustrated pins and sockets are cylindrical such that the pins can rotate in the sockets to allow some flexing of the implement and foundation frame 103 during operation.
It is contemplated that the beam engagement member 122 could instead be provided by the socket and the implement engagement member 124 provided by the pin. It is also contemplated that other engagement mechanisms could be used as well.
A hydraulic fluid source 132 of the motor assembly 108 is operative to direct pressurized hydraulic fluid into the hydraulic cylinders 120 to move the lift arms 116 from the loading position to the operating position and operative to exert a bias force BF on the lift arms 116 urging the lift arms 116 toward the operating position as shown in Fig. 17. The hydraulic fluid source 132 directs pressurized hydraulic fluid to the hydraulic cylinders 120 at a pressure selected to exert the desired bias force BF which holds the beam and implement engagement members 122, 124 together in engagement. The engagement supports the implement 115 on the foundation frame 103 and also serves to prevent lateral movement of the right mounting beam 109R with respect to the left mounting beam 109L. Thus if an opposite force F is exerted on the lift arm 116 away from the operating position toward the loading position that is greater than the bias force BF, the lift arm 116 will move away from the operating position toward the loading position and pressurized hydraulic fluid will move out of the hydraulic cylinder 120 and back to hydraulic fluid source 132.
Using the hydraulic cylinders 120 to exert a strong bias force BF toward the operating position allows the lift arms 116 to move slightly in response to sudden forces on the apparatus 1 during operation and then be pushed back into the desired operating position.
Such sudden forces can break bolts and like fasteners and this slight movement of the lift arms 116 can relieve the strain on other parts of the apparatus 1 and reduce the occurrence of damage.
Loss of hydraulic pressure is typically sensed and the apparatus 1 powered off to avoid damage. If desired a releasable lock mechanism 134 such as schematically illustrated in Fig. 18 may be provided as well to secure the lift arms 116 in the operating position with the implement engagement members 124 engaged with the corresponding beam engagement members 122. Fig. 18 illustrates a loose engagement which will allow some flexing as discussed with respect to the hydraulic cylinders 120 exerting a bias force BF.
It is contemplated that the hydraulic fluid source could also be configured to conventionally extend and retract the hydraulic cylinders and lock them to keep the lift arms in the operating position with no hydraulic fluid allowed to move in and out as is also known in the art. The lock mechanism 134 would also then maintain the engagement of the beam and implement engagement members 122, 124.

In the illustrated apparatus 101 the shaft 128 on each implement attachment mechanism 126 extends between substantially vertical mounting plates 136. Portions 136A
of the mounting plates 136 that are next to the hooks 118 when the foundation frame 103 is moving into the implement loading position, as seen in Fig. 15, slope laterally away from the shaft 128 to guide the corresponding lift arm 116 and corresponding hook 118 toward the shaft 128.
The implement frame 115 can be incorporated into wide variety of implements.
The implement mounting system of the apparatus 101 comprising corresponding beam and implement attachment mechanisms 114, 126 provides a secure mounting of the implement 115 to the foundation frame 103 and also provides a simple and .effective implement moving mechanism to raise the implement 115 from the idle position supported on the ground to the operating position supported on the foundation frame 103.
The foregoing is considered as illustrative only of the principles of the invention.
Further, since numerous changes and modifications will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction .and operation shown and described, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.
Correct alignment of the rigid structural member 17, and thus the implement 15, with the foundation frame 3 is facilitated since the conical projection 27A can enter an edge of the conical recess 27B and will be forced into alignment as the conical projection 27A moves fully into the conical recess 27B.
Further a lock recess 31 can be provided in the conical projection 27A
:configured to receive a lock member 33 that is biased by a spring 35 or the like when the conical projection 27A and recess 27B are fully engaged. A latch release 29 is mounted on the open side of the rigid structural member 17.
The illustrated latch members 25 prevent lateral movement of one beam 9 with respect to the other however up and down movement of one mounting beam 9 with respect to the other is not significantly reduced.
Figs. 7 and 8 schematically illustrate an alternate arrangement wherein the beam attachment mechanisms 13 and the implement attachment mechanisms 19' comprise plates 37 attached to the rigid structural member 17' and to the mounting beams 9' and defining mounting holes 39. The implement via the rigid structural member 17' is attached to the mounting beams 9' by a bolt 41 through the holes 39 in the plates 37.
The implement apparatus 1 can be configured to perform a variety of agricultural operations. Fig. 9 schematically illustrates an implement 115 comprising agricultural product tanks 151 mounted to the mounting beams 109 of the foundation frame 103 by plates 137 and bolts 141. Furrow openers 153 are mounted on a laterally ex/ending implement frame 155 and the implement 115 is configured to seed a crop. =
Fig. 10 schematically illustrates an implement 215 comprising cultivator shanks 257 mounted on a laterally extending implement frame 259 and configured to cultivate a field surface.
Fig. 11 schematically illustrates an implement 315 comprising a liquid tank 361 and sprayer nozzles 363 mounted on a laterally extending sprayer boom and configured to spray liquid chemicals on a crop.
The disclosed implement apparatus 1 adds structural rigidity to a foundation frame which includes mounting beams 9 extending from a base, such as a base beam 11. With no connection between the first and second mounting beams 9A, 9B except at the base beam 11, there is a clear space between the mounting beams 9 which facilitates loading of implements that extend above the mounting beams 9, such as the grain tank 15 however since the mounting beams 9 are connected to each other only at their ends fixed to the base beam 11 forces exerted on the opposite outer ends thereof can put severe stresses on the connection to the base beam 11. By attaching the rigid structural member 17 to outer portions of the mounting beams 9, lateral movement of one beam with respect to the other is prevented and so lateral forces on the outer end of one beam 9 are resisted by both beams 9A. 9B.
It is contemplated that in the operations contemplated up and down movement of one mounting beam 9 with respect to the other will not subject the connection of the mounting beams 9 to the base beam to excessive forces.
Figs. 12 ¨ 19 illustrate an agricultural implement apparatus 101 comprising a U-shaped foundation frame 103 supported on wheels 105 for travel over a ground surface where the foundation frame 103 includes right and left substantially parallel and laterally spaced mounting beams 109R, 109L fixed at inner ends thereof to a substantially horizontal base beam 111 and extending in an outward direction OD from the base beam 111 to outer ends 110 thereof remote from the base beam 111 such that an open implement area 112 is provided between the mounting beams 109 from the outer ends 110 of the mounting beams to the base beam 111. The illustrated foundation frame 103 is self-propelled and includes a motor assembly 108 that provides hydraulic power to drive and steer the wheels 105, and provide any other implement power requirements. For clarity of illustration the motor assembly 108 is not shown in Figs. 12 and 13.
An implement is configured to perform an agricultural operation such as seeding, cultivating, spraying as described above, and only the implement frame 115 of the implement is illustrated to facilitate viewing the attachment of the implement frame to the foundation frame 103. Also as described above the implement is configured to rest on the ground surface when in an idle position, as illustrated in the top view of Fig. 12, with the foundation frame 103 approaching. The implement frame 115 is configured to attach to the foundation frame 103 in the open implement area 112 when in an operating position as shown in Figs. 13 and 19.
In the illustrated apparatus 101 four beam attachment mechanisms 114 are mounted to the foundation frame 103. Right and left outer beam attachment mechanisms 114RO, 114L0 are mounted to corresponding right and left end portions of the con-esponding right and left mounting beam s 109R, 109L, and right and left inner beam attachment mechanisms 114RI, 114LI are mounted to the base beam 111 .
Corresponding right and left outer implement attachment mechanisms 126R0, 126L0 are 'mounted to the implement 115 at locations corresponding to locations of the right and left outer beam attachment mechanisms 114R0, 114L0, and corresponding right and left inner implement attachment mechanisms 126R1, 126L1 are mounted to the implement 115 at locations corresponding to locations of the right and left inner beam attachment mechanisms 114R1, 114LI. The four connections raise the implement 115 up from the idle position in a level orientation and then hold the implement 115 securely to the foundation frame 103.
Each beam attachment mechanism 114 comprises a lift arm 116 pivotally attached at an inner end thereof to the corresponding beam about a lift pivot axis LPA
oriented . substantially horizontally and perpendicular to the outward direction OD.
The lift arms 116 define a hook 118 at the outer ends thereof and are pivotal from a loading position shown in Figs. 14 and 16 extending in the outward direction OD to an operating position extending upward as shown in Fig. 17. A hydraulic cylinder 120 is operative to pivot the lift arm 116 between the loading position and the operating position and a beam engagement member 122 is operative to engage a corresponding implement engagement member 124 attached to the implement 115.
For each beam attachment mechanism 114, a corresponding implement attachment mechanism 126 is mounted to the implement 115. Each implement attachment mechanism 126 comprises a shaft 128 oriented substantially horizontally and perpendicular to the outward direction OD, and the implement engagement member 124.
The attachment mechanisms 114, 126 are configured such that, with the lift arms 116 in the loading position, the foundation frame 103 is movable to an implement loading position with respect to the implement 115 in the idle position where the hook 118 of each beam attachment mechanism 114 is located under the shaft 128 of the Corresponding implement attachment mechanism 126. Figs. 12, 14, and 15 show the lift arm 116 in the loading position approaching the implement attachment mechanisms 126 on the implement 115, and Fig. 14 shows, in phantom lines, the lift arm 116 in the implement loading position with the hook 118 under the shaft 128.
With the foundation frame 103 in implement loading position, pivoting the lift arms 116 toward the operating position of Fig. 17 moves the implement 115 upward and in an inward direction ID. Fig. 16 shows the lifting arm 116 in an intermediate position partially raised from the loading position of Fig. 15 and the implement 115 raised from its idle position supported on the ground. When the lifting arm 116 reaches the operating position of .Fig. 17, each implement engagement member 124 moves into engagement with the corresponding beam engagement member 122 and the implement 115 is fully raised and secured in the operating position as shown in Figs. 13, 17, and 19.
Removing the implement 115 from the foundation frame 103 and returning same to the idle position supported on the ground is accomplished by activating the hydraulic cylinders 120 in the opposite direction to move the lift arms 116 from the operating position to the loading position which moves the implement 115 forward and downward to the idle position, where the foundation frame 103 and attached beam attachment mechanisms 114 can be moved away from the implement 115 and the corresponding implement attachment mechanisms 126.
In the illustrated apparatus 101 the beam engagement member 122 is provided by a pin configured to slide into the socket that forms the implement engagement member 124.
The pin comprises a tapered end 130 operative to guide the pin into the socket. The illustrated pins and sockets are cylindrical such that the pins can rotate in the sockets to allow some flexing of the implement and foundation frame 103 during operation.
It is contemplated that the beam engagement member 122 could instead be provided by the socket and the implement engagement member 124 provided by the pin. It is also contemplated that other engagement mechanisms could be used as well.
A hydraulic fluid source 132 of the motor assembly 108 is operative to direct pressurized hydraulic fluid into the hydraulic cylinders 120 to move the lift arms 116 from the loading position to the operating position and operative to exert a bias force BF on the lift arms 116 urging the lift arms 116 toward the operating position as shown in Fig. 17. The hydraulic fluid source 132 directs pressurized hydraulic fluid to the hydraulic cylinders 120 at a pressure selected to exert the desired bias force BF which holds the beam and implement engagement members 122, 124 together in engagement. The engagement supports the implement 115 on the foundation frame 103 and also serves to prevent lateral movement of the right mounting beam 109R with respect to the left mounting beam 109L. Thus if an opposite force F is exerted on the lift arm 116 away from the operating position toward the loading position that is greater than the bias force BF, the lift arm 116 will move away from the operating position toward the loading position and pressurized hydraulic fluid will move out of the hydraulic cylinder 120 and back to hydraulic fluid source 132.
Using the hydraulic cylinders 120 to exert a strong bias force BF toward the operating position allows the lift arms 116 to move slightly in response to sudden forces on the apparatus 1 during operation and then be pushed back into the desired operating position.
Such sudden forces can break bolts and like fasteners and this slight movement of the lift arms 116 can relieve the strain on other parts of the apparatus 1 and reduce the occurrence of damage.
Loss of hydraulic pressure is typically sensed and the apparatus 1 powered off to avoid damage. If desired a releasable lock mechanism 134 such as schematically illustrated in Fig. 18 may be provided as well to secure the lift arms 116 in the operating position with the implement engagement members 124 engaged with the corresponding beam engagement members 122. Fig. 18 illustrates a loose engagement which will allow some flexing as discussed with respect to the hydraulic cylinders 120 exerting a bias force BF.
It is contemplated that the hydraulic fluid source could also be configured to conventionally extend and retract the hydraulic cylinders and lock them to keep the lift arms in the operating position with no hydraulic fluid allowed to move in and out as is also known in the art. The lock mechanism 134 would also then maintain the engagement of the beam and implement engagement members 122, 124.
