DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

[0042] FIGS. 1-5 schematically illustrate an embodiment of an agricultural implement apparatus 1 of the present disclosure for mounting on a U-shaped foundation frame 3 supported on wheels 5 for travel over a ground surface 7. 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.

[0043] 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.

[0044] 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.

[0045] 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 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.

[0046] 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.

[0047] 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.

[0048] 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 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.

[0049] In the illustrated apparatus 1 the jack handles 23 are manipulated to move the implement 15 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 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.

[0050] It is contemplated as well that in some configurations of the implement, the implement 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.

[0051] 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 27A 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 attachment mechanisms 19 bear against the beam attachment mechanisms 13 to engage the latch mechanisms 25.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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 extending implement frame 155 and the implement 115 is configured to seed a crop.

[0057] 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.

[0058] FIG. 11 schematically illustrates an implement 315 comprising a liquid tank 361 and sprayer nozzles 363 mounted on a laterally extending sprayer boom 365 and configured to spray liquid chemicals on a crop.

[0059] 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.

[0060] 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.

[0061] FIGS. 12-16 schematically illustrate a ramp raising system installed on the foundation frame 3 and implement 67 for raising the implement 67 off the ground surface 7 and up to the operating position supported on the foundation frame 3. The raising system comprises a plurality of ramp members 69 attached to one of the foundation frame 3 and the implement 67, each ramp member 69 including a sloping bearing surface 69S, and a corresponding plurality of support members 79 attached to the other of the foundation frame 3 and the implement 67. The ramp members 69 and the support members 79 are configured such that as the implement 67 moves toward the operating position, each support member 79 bears against the sloping bearing surface 69S of the corresponding ramp member 69 and exerts an upward force on the implement 67.

[0062] FIGS. 12-16 schematically illustrate a system where the ramp members 69 are mounted on the foundation frame 3 and the support members 79 are mounted on the implement 67. In this arrangement the sloping bearing surface 69S of the ramp members 69 is the top surface. First and second ramp members 69A, 69B are attached to corresponding first and second side beams 9A, 9B. Each ramp member 69 extends substantially parallel to the corresponding side beam 9 from a base end 71 thereof that is nearest the base beam 11, to a remote end 73 thereof. Each ramp member 69 comprises a substantially horizontal flat portion 75 extending from the base end 71 thereof to a midpoint thereof, and an inclined portion 77 sloping downward from the midpoint to the remote end 73 of the ramp member 69.

[0063] The raising system further comprises first and second support members 79A, 79B attached to sides of the implement 67 and are configured to move up the sloping inclined portions 77 of the corresponding first and second ramp members 69A, 69B as the implement 67 moves toward the operating position. When the implement 67 is moved all the way to the operating position of FIG. 14 it is supported on the flat portions 75 of the ramp members when in the operating position as seen in FIG. 16.

[0064] The illustrated support members 79 each comprise a support wheel 81 configured to roll along the corresponding ramp member 69, and a support surface 83 adjacent to and above a bottom edge of the support wheel 81 as schematically illustrated in FIG. 15. Thus as the support wheel 81 rolls up ramp member 69 the support surface 83 is above the ramp member 69 as seen in FIG. 15. When the implement 67 moves into the operating position of FIG. 14, each wheel 81 moves beyond the base end 71 of the corresponding ramp member 69 so that the wheel 81 no longer keeps the support surface 83 above the ramp member 69, and instead each support surface 83 rests on the corresponding flat portion 75 of each ramp member 69 supporting the implement 67 when the implement 67 is in the operating position.

[0065] An extendable connection actuator 85 is attached to the foundation frame 3 and is releasably attachable to the implement 67 by a pin 87 engaging a hook 89 on the implement 67. As the actuator 85 extends the pin 87 rides over the top of the hook 89 and then falls down behind the hook 89. Retracting the actuator 85, typically a hydraulic cylinder, then pulls the implement 67 toward the foundation frame 3 such that the support members 79 move up the ramp members 69 and the implement 67 moves to the operating position. Extending the actuator 85 will push the support members 79 away from the foundation frame 3 such that the support wheels 81 again roll up onto the ramp members 69 and down to move the implement 67 to the idle position. The actuator 85 can also be configured as a constantly pressurized hydraulic cylinder so that same exerts a substantially constant force on the hook 89 in the retracting direction R to keep the implement 67 in the operating position.

[0066] The implement 67 is supported in the idle position by legs 91. In the operating position the legs 91 are sufficiently far above the ground 7 that they will not interfere with implement operations. Further ramp members 69 can be attached to the foundation frame 3 at convenient locations, each with a corresponding support member 79 mounted on the implement 67. In the illustrated foundation frame 3, third and fourth ramp members 69C, 69D are attached to the base beam 11, and wherein the implement 67 comprises a corresponding third and fourth support members 79C, 79D configured to move up the inclined portion of the ramp members 69C, 69D as the implement 67 moves toward the operating position.

[0067] FIGS. 19-21 schematically illustrate an alternate system where the support members 79′ are mounted on the foundation frame 3′ and the ramp members 69′ are mounted on the implement 67′. In this arrangement the sloping bearing surface 69S′ of the ramp members 69′ is the bottom surface. Each ramp member 69′ extends substantially parallel to the path P of the foundation frame 3′ from a base end 71′ thereof that is nearest the base beam 11′ of the approaching foundation frame 3′, to a remote end 73′ thereof. Each ramp member 69′ again comprises a substantially horizontal flat portion 75′ extending from the remote end 73′ thereof to a midpoint thereof, and an inclined portion 77′ sloping upward from the midpoint to the base end 71′ of the ramp member 69′.

[0068] Thus it can be seen that a plurality of ramp members 69, 69′ and a corresponding number of support members 79, 79′ can be mounted on either or both of the foundation frame 3, 3′ and implement 67, 67′ as required by the configuration of various implements. To facilitate proper alignment of the implement and foundation frame, FIG. 22 schematically illustrates the sloping bearing surface 69S″ of the ramp member 69″ formed as a trough with a flat bottom generally the same width as the width of the support wheel 81″. If slightly misaligned when contacting the bearing surface 69S″, the wheel 81″ will slide to the bottom of the trough in the desired aligned position.

[0069] FIGS. 25 and 26 illustrate a system 201 using a ramp member 269 in combination with a raising arm 259 to move an implement 221 from the idle position of FIG. 25 to the operating position of FIG. 26 supported on the foundation frame 203. The support member 279 is mounted on the implement 221 and configured to engage the ramp member 269 about the same time as the pin 260 on the implement 221 engages the recess 262 in the raising arm 259. The actuator hydraulic cylinder 285 is then retracted moving the raising arm 259 and pin 260 up to move the first end 221A of the implement 221 up and toward the foundation frame 203 and also moves the support member 279 upward along the ramp member 269. Constant hydraulic pressure retracting the actuator hydraulic cylinder 285 keeps the implement in the operating position, and when it is desired to move the implement 221 off the foundation frame 203 into the idle position resting on legs 291 the actuator hydraulic cylinder 285 is simply extended.

[0070] Thus the system 201 utilizes a combination of the ramp members 69 shown in FIG. 12 and a raising arm 259 with the actuator hydraulic cylinder 285 performing the function of the hydraulic connection actuator of FIGS. 12-20. Other such combinations of the described arrangements are contemplated as well.

[0071] Further to facilitate alignment, FIGS. 23 and 24 schematically illustrate a guide system comprising a circular guide aperture 92 defined in the selected implement 15, and a conical guide member 94 extending from the foundation frame 3. The opposite arrangement with the circular guide aperture 92 defined in the foundation frame 3, and the conical guide member 94 extending from the selected implement 21 will function equally as well. The guide member 94 and the guide aperture 92 are configured such that as the implement moves toward the operating position as seen in FIG. 23, the guide member 94 enters the guide aperture 92, and when the implement 21 is in the operating position the guide member 94 substantially fills the guide aperture 92 as seen in FIG. 24. Thus slight misalignments are corrected when the implement achieves the operating position. The guide member 94 and guide aperture 92 can be oriented vertically or horizontally however with the guide member 94 extending horizontally as illustrated, when the guide member 94 enters the guide aperture 92, the conical edge 96 bears against the top of the guide aperture 92 and forces the implement 15 upward, such that when the implement 15 is in the operating position, the implement 15 bears downward on the guide member 94 and is supported on the foundation frame 3.

[0072] A system for loading granular material into a fill opening of a bin 82 is schematically illustrated in FIGS. 27 and 28. The system comprises a conveyor 78 mounted on wheels for movement along the ground surface 7. The conveyor 78 includes an upper conveyor discharge 78A and a lower conveyor intake 78B. A conveyor control system 76 is operative to move and steer the conveyor and to selectively raise and lower the conveyor intake and the conveyor discharge. A location system 74 is connected to the conveyor control system and is operative to guide the conveyor to a bin loading position shown in FIG. 27 where the conveyor discharge 78A is oriented to discharge into the bin fill opening 84 and the conveyor intake 78B is oriented to receive granular material from an incoming transport vehicle 72A. The conveyor control system 76 could be partially manually controlled, with an operator responding to signals from the location system, or fully automated.

[0073] The illustrated location system is further operative to guide the conveyor 78 to a bin unloading position illustrated in FIG. 28 where the conveyor intake 78B is oriented to receive granular material from a bin discharge opening 86 and the conveyor discharge 78A is oriented to discharge granular material into an outgoing transport vehicle 72B.

[0074] The location system can comprise a global positioning satellite receiver 70 mounted on the conveyor 78 and operative to determine a conveyor discharge location of the conveyor discharge 78A and a conveyor intake location of the conveyor intake 78B, and wherein a bin fill location of the bin fill opening 84 and a bin discharge location of the bin discharge opening 86 are programmed into the location system.

[0075] FIG. 29 schematically illustrates a plurality of bins 82A, 82B, 82C, where bin fill locations corresponding to bin fill openings 84A, 84B, 84C, and bin discharge locations corresponding to bin discharge openings 86A, 86B, 86C are programmed into the location system 74 and the location system is operative to guide the conveyor 78 to the bin loading and unloading positions with respect to each bin.

[0076] Alternatively as schematically illustrated in FIG. 27 the location system 74 can include a bin fill homing device 80A mounted adjacent to the bin fill opening 84 and a bin discharge homing device 80B mounted adjacent to the bin discharge opening 86. A conveyor discharge homing device 70A is mounted adjacent to the conveyor discharge 78A and a conveyor intake homing device 70B mounted adjacent to the conveyor intake 78B and the devices 70A, 70B connect through the location system 74 to the conveyor control system 76 to move and steer the conveyor 78.

[0077] 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.
