Abstract
A foldable rear boom section of an agricultural product applicator includes at least one first tube connected to a first end of a respective at least one second tube and a hinge assembly coupled to the first and second tubes and configured to pivot the second tube with respect to the first tube about a pivot axis. Further, a nozzle is connected to a second end of the second tube. Pivoting the first and second tubes about the pivot axis causes the foldable rear boom section and the nozzle to transition between an extended position and a retracted position.

A foldable rear boom section of an agricultural product applicator comprising:
- a support bar;
- a mounting bracket operably coupled with the support bar;
- at least one first tube connected to a first end of a respective at least one second tube;
- a hinge assembly coupled to the first and second tubes and configured to pivot the second tube with respect to the first tube about a pivot axis, the hinge assembly including a hinge base coupled to the first tube and the mounting bracket, the hinge base including one or more hinge base plates extending from a first end adjacent the second tube to a second end spaced apart from the second tube, the hinge assembly further including a pivot arm coupled to the second tube, the pivot arm including one or more pivot arm plates coupled to the second tube at a first end of the one or more pivot arm plates, wherein each pivot arm plate of the one or more pivot arm plates extends upward from the first end of the pivot arm plate to a pivot point and then upward from the pivot point to a second end of the pivot arm plate;
- a nozzle connected to a second end of the second tube;
- wherein pivoting the first and second tubes about the pivot axis causes the foldable rear boom section and the nozzle to transition between an extended position and a retracted position,
- wherein the first end of each of the one or more hinge base plates and the pivot point of each of the one or more pivot arm plates are pivotably coupled together and configured to allow the first and second tubes to pivot with respect to each other, and
- wherein the hinge assembly further includes an actuator configured to cause pivoting of the pivot arm with respect to the hinge base in order to cause pivoting of the second tube with respect to the first tube, the actuator being coupled at one end to the second end of each of the one or more pivot arm plates.
