Abstract
A break-away apparatus for a boom arm is positioned at a joint between a main boom and a boom tip to allow the boom tip to assume a neutral position and forward, rearward, and upward positions. A hinge assembly is positioned between the boom tip and main boom. The hinge assembly includes an upper ball joint, a first hinge, and a second hinge. The boom tip is movable relative to the main boom about an axis of the first hinge, about an axis of the second hinge axis, and/or about a pivot defined by the upper ball joint. A first spring assists a return of the boom tip to the neutral position.
Claims15
A boom arm assembly comprising:
- a main boom;
- a boom tip configured to assume a neutral position and to pivot to a forward position, a rearward position, and an upward position relative to the main boom;
- an upper ball joint connecting the main boom to the boom tip;
- a first hinge connected to the main boom, the first hinge having a first hinge axis defined between the upper ball joint and the first hinge;
- a second hinge connected to the boom tip, the second hinge having a second hinge axis defined between the upper ball joint and the second hinge;
- a hinge connecting bar connecting the first hinge to the second hinge;
- a first hinge seat attached to the main boom and having a resilient insert shaped to fit about a first portion of the hinge connecting bar;
- a second hinge seat attached to the boom tip and having a resilient insert shaped to fit about a second portion of the hinge connecting bar;
- and
- a spring assembly connecting the boom tip to the main boom at a second ball joint, the spring assembly comprising a first spring and an elongated rod, wherein the first spring applies a holding force on the boom tip toward the main boom such that the spring assembly provides a break-away threshold;
- wherein the boom tip is movable relative to the main boom about the first hinge axis, the second hinge axis, and a pivot point defined by the upper ball joint when the break-away threshold is exceeded;
- wherein the first spring urges the boom tip toward the neutral position relative to the main boom when the boom tip is not in the neutral position.
A sprayer vehicle, comprising:
- a frame supported by a plurality of wheels;
- an engine carried by the frame and configured to drive at least one of the plurality of wheels;
- a storage tank carried by the frame;
- a main boom carried by the frame;
- a boom tip configured to assume a neutral position and to pivot to a forward position, a rearward position, and an upward position relative to the main boom;
- an upper ball joint connecting the main boom to the boom tip;
- a first hinge connected to the main boom, the first hinge having a first hinge axis defined between the upper ball joint and the first hinge;
- a second hinge connected to the boom tip, the second hinge having a second hinge axis defined between the upper ball joint and the second hinge;
- a hinge connecting bar connecting the first hinge to the second hinge;
- a first hinge seat attached to the main boom and having a resilient insert shaped to fit about a first portion of the hinge connecting bar;
- a second hinge seat attached to the boom tip and having a resilient insert shaped to fit about a second portion of the hinge connecting bar;
- and
- a spring assembly connecting the boom tip to the main boom at a second ball joint, the spring assembly comprising a first spring and an elongated rod, wherein the first spring applies a holding force on the boom tip toward the main boom such that the spring assembly provides a break-away threshold;
- wherein the boom tip is movable relative to the main boom about the first hinge axis, the second hinge axis, and a pivot point defined by the upper ball joint when the break-away threshold is exceeded;
- wherein the first spring urges the boom tip toward the neutral position relative to the main boom when the boom tip is not in the neutral position.
