Abstract

A fastening system for an agricultural system includes a first mounting plate coupled to a first component and a second mounting plate coupled to a second component. The second mounting plate aligns with the first mounting plate. The fastening system also includes a coupling assembly coupled to the first mounting plate by a retaining fastener. The coupling assembly comprises two clamping plates which 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. The retaining fastener extends through the two clamping plates. An alignment fastener also extends through the two clamping plates and is selectively tightened while the coupling assembly is in the second position to drive the two clamping plates to couple the first and second mounting plates to one another.

First claim

The invention claimed is:

1. A fastening system for an agricultural system, comprising:
a first extension coupled to a first component of the agricultural system;
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;
a coupling assembly comprising two clamping plates coupled to the first extension by a retaining fastener extending through respective retaining openings in the two clamping plates and in the first extension; and
at least one alignment fastener extending through respective alignment openings in the two clamping plates, wherein the coupling assembly is configured to rotate about the retaining fastener from a first position configured to facilitate alignment of the first and second extensions to a second position that at least partially sandwiches the first and second extensions between the two clamping plates of the coupling assembly, the at least one alignment fastener is configured to maintain alignment of the two clamping plates, and the retaining fastener and the at least one alignment fastener 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.

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

3. The fastening system of claim 1 , wherein the first extension comprises at least one first open-ended slot, the second extension comprises at least one second open-ended slot, the at least one first open-ended slot is configured to be aligned with the at least one second open-ended slot while the first extension is aligned with the second extension, and the at least one first open-ended slot and the at least one second open-ended slot are configured to receive the at least one alignment fastener as the coupling assembly is rotated from the first position to the second position.

4. The fastening system of claim 3 , wherein the at least one first open-ended slot and the at least one second open-ended slot are curved to accommodate receiving the at least one alignment fastener.

5. The fastening system of claim 1 , wherein the retaining fastener and the at least one alignment fastener comprise:
respective heads disposed on a first side of the retaining fastener 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 of the retaining fastener 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.

6. The fastening system of claim 1 , wherein the respective tightening features comprise wingnuts.
