Abstract

The present disclosure describes a fastening system for an agricultural system. The fastening system includes a first mounting plate coupled to a first component of the agricultural system and a second mounting plate coupled to a second component of the agricultural system, in which the second mounting plate is configured to be aligned with the first mounting plate. The fastening system also includes a coupling assembly coupled to the first mounting plate by at least one retaining fastener, in which the coupling assembly comprises two clamping plates configured to move from a first position that facilitates alignment of the first and second mounting plates to a second position that at least partially sandwiches the first and second mounting plates between the two clamping plates of the coupling assembly. The at least one retaining fastener extends through the two clamping plates of the coupling assembly. At least one alignment fastener also extends through the two clamping plates and is configured to be selectively tightened while the coupling assembly is in the second position to establish a compressive force that drives the two clamping plates to couple the aligned first and second mounting plates to one another.

First claim

The invention claimed is:

1. An agricultural system, comprising:
a first mounting plate coupled to a first component of the agricultural system;
a second mounting plate coupled to a second component of the agricultural system, wherein the second mounting plate is configured to be aligned with the first mounting plate; and
a coupling assembly coupled to the first mounting plate by at least one retaining fastener, wherein the coupling assembly comprises two clamping plates configured to move, relative to the first mounting plate and the second mounting plate, from a first position that facilitates alignment of the first and second mounting plates to a second position that at least partially positions the first and second mounting plates between the two clamping plates of the coupling assembly, wherein the at least one retaining fastener extends through the two clamping plates of the coupling assembly, and wherein at least one alignment fastener extending through the two clamping plates is configured to be selectively tightened while the coupling assembly is in the second position to establish a compressive force that drives the two clamping plates to couple the aligned first and second mounting plates to one another;
wherein the first mounting plate comprises a close-ended opening through which a first retaining fastener of the at least one retaining fastener extends to couple the coupling assembly to the first mounting plate, such that the two clamping plates of the coupling assembly are configured to move between the first position and the second position while the first retaining fastener extends within the close-ended opening.

2. The agricultural system of claim 1 , wherein the first component comprises a chassis and the second component comprises a skid.

3. The agricultural system of claim 1 , wherein the first mounting plate is integrally formed with the first component and the second mounting plate is integrally formed with the second component.

4. The agricultural system of claim 1 , wherein the close-ended opening comprises a close-ended slot.

5. The agricultural system of claim 4 , wherein the first mounting plate comprises:
an additional close-ended slot through which a second retaining fastener of the at least one retaining faster extends to couple the coupling assembly to the first mounting plate, such that the two clamping plates are configured to move linearly between the first position and the second position while the second retaining fastener extends within the additional close-ended slot.

6. The agricultural system of claim 1 , wherein the first mounting plate comprises at least one first open-ended slot and the second mounting plate comprises at least one second open-ended slot, the at least one first open-ended slot and the at least one second open-ended slot are configured to be aligned with one another while the first mounting plate is aligned with the second mounting plate, and the at least one alignment fastener extending through the two clamping plates is configured to extend into the at least one first open-ended slot and the at least one second open-ended slot while the coupling assembly is in the second position.

7. The agricultural system of claim 6 , wherein the at least one alignment fastener comprises:
a head disposed on a first side of the at least one alignment fastener and configured to contact a top surface of a first clamping plate of the two clamping plates; and
a tightening feature disposed on a second side of the at least one alignment fastener opposite the first side, wherein the tightening feature is configured to be selectively tightened such that the tightening feature contacts a bottom surface of a second clamping plate of the two clamping plates and the head and the tightening feature, upon tightening, exert a compressive force that drives the two clamping plates to couple the first and second mounting plates to one another.

8. The agricultural system of claim 7 , wherein the tightening feature comprises a locknut.

9. An agricultural system, comprising:
a first extension coupled to a first component of the agricultural system, wherein the first extension comprises two close-ended slots;
a second extension coupled to a second component of the agricultural system, wherein the second extension is configured to be aligned with the first extension; and
a coupling assembly comprising two clamping plates coupled to the first extension by two retaining fasteners extending through respective openings in the two clamping plates and through the two close-ended slots of the first extension, wherein the coupling assembly, via the two retaining fasteners extending through the two close-ended slots, is configured to move, relative to the first extension and the second extension, linearly along the first extension from a first position configured to facilitate alignment of the first and second extensions to a second position that at least partially positions the first and second extensions between the two clamping plates of the coupling assembly, and the two retaining fasteners are configured to be selectively tightened while the coupling assembly is in the second position to establish a compressive force that drives the two clamping plates to couple the first and second extensions to one another.

10. The agricultural system of claim 9 , wherein the first component comprises a chassis and the second component comprises a skid.

11. The agricultural system of claim 10 , wherein the first extension is integrally formed with the first component and the second extension is integrally formed with the second component.

12. The agricultural system of claim 9 , wherein the first extension comprises at least one first open-ended slot and the second extension comprises at least one second open-ended slot, the at least one first open-ended slot and the at least one second open-ended slot are configured to be aligned with one another while the first extension is aligned with the second extension, and at least one alignment fastener extending through the two clamping plates is configured to extend into the at least one first open-ended slot and the at least one second open-ended slot while the coupling assembly is in the second position.

13. The agricultural system of claim 12 , wherein the two retaining fasteners and the at least one alignment fastener comprise:
respective heads disposed on a first side of the two retaining fasteners and the at least one alignment fastener and configured to contact a top surface of a first clamping plate of the two clamping plates; and
respective tightening features disposed on a second side of the two retaining fasteners and the at least one alignment fastener opposite the first side, wherein the respective tightening features are configured to be selectively tightened such that the respective tightening features contact a bottom surface of a second clamping plate of the two clamping plates and the respective heads and the respective tightening features, upon tightening, exert a compressive force that drives the two clamping plates to couple the first and second extensions to one another.

14. The agricultural system of claim 13 , wherein the respective tightening features comprise wingnuts.

15. A fastening system for an agricultural system, wherein the fastening system comprises:
a first extension configured to be coupled to a first component of the agricultural system, wherein the first extension comprises two close-ended slots;
a second extension configured to be coupled to a second component of the agricultural system, wherein the second extension is configured to
