Abstract

A boom center section for an agricultural machine includes a bulkhead having a first end and a second end, at least one bulkhead opening located adjacent at least one of the first and the second ends of the bulkhead, and at least one connection assembly disposed within the at least one bulkhead opening. Each bulkhead opening is formed through a first wall of the bulkhead. Each connection assembly includes a plurality of connectors.

First claim

We claim:

1. A boom center section for an agricultural machine comprising:
a bulkhead having a first end, a second end, a front wall and a rear wall;
at least a first bulkhead opening located adjacent at least one of the first and the second ends of the bulkhead, and at least a second bulkhead opening to the other of the first and the second ends of the bulkhead;
a first perimeter wall forming a first tubular member and a second perimeter wall forming a second tubular member, each of the first and the second perimeter walls positioned within the front wall within the at least first bulkhead opening and the at least second bulkhead opening, respectively, the first and the second perimeter walls extending a distance toward the rear wall and configured to form an open cavity between the front wall and the rear wall of the bulkhead;
each of the first tubular member and the second tubular member containing, respectively, a connection assembly which contains a plate perpendicular to the perimeter wall, and the plate being recessed from the front wall and having a plurality of connections, wherein the plurality of connectors extend from their respective plate to the front wall; and
the rear wall of the bulkhead positioned against both of the first and the second perimeter walls, a plurality of openings formed in the rear wall adjacent to the first perimeter wall and the second perimeter wall and configured to align with the plurality of connectors of each respective connection assembly, wherein each connector of the plurality of connectors also respectively extend from their respective plate through a space formed by the cavity and through their respective plurality of openings in the rear wall.

2. The boom center section of claim 1 wherein the at least first bulkhead opening is located in a first portion of the bulkhead adjacent the first end of the bulkhead; and
the at least second bulkhead opening is located in a second portion of the bulkhead adjacent the second end of the bulkhead.

3. The boom center section of claim 1 wherein the plurality of connectors of each connection assembly includes at least one of a hydraulic connector, a electrical connector, a pneumatic connector, and a product connector.

4. The boom center section of claim 1 wherein the plurality of connectors includes quick connect fittings.

5. The boom center section of claim 1 wherein at least a portion of each connector of the plurality of connectors of each connector assembly is positioned to extend a distance away from the back wall.

6. The boom center section of claim 1 wherein a rear wall of the bulkhead is coupled to the agricultural sprayer by way of a plurality of lift arms.
