Abstract

A breakaway adapter system is provided that allows the same breakaway joints and breakaway boom segments to be used with either front-mounted or rear-mounted booms. The adapter system may have a multi-piece construction with a secondary boom segment end cap that can be reconfigured to receive either a left-side hinged or right-side hinged adapter hinge bracket or hinge plate. This allows a main boom body to be reversed for switching between front-mounted and rear-mounted configurations by rotating the main boom body 180-degrees while retaining breakaway joints and breakaway boom segments in rearward deflecting positions.

First claim

What is claimed is:

1. A breakaway adapter system facilitating both front-mounted and rear-mounted configurations of a sprayer boom of an agricultural sprayer, wherein the sprayer boom includes a main boom body connected to the agricultural sprayer with the main boom body having outer ends, a sprayer facing side facing toward the sprayer, and an outwardly facing side facing away from the sprayer, wherein the breakaway adapter system comprises:
a pair of breakaway boom segments arranged outwardly beyond outer ends of the main boom body;
a pair of breakaway joints arranged between the outer ends of the main boom body and the pair of breakaway boom segments, wherein the breakaway joints are configured to allow the breakaway boom segments to deflect in rearward deflection directions; and
a pair of adapter arrangements between the outer ends of the main boom body and the pair of breakaway joints, each adapter arrangement configured to engage and support either breakaway joint of the pair of breakaway joints;
wherein when the sprayer boom is in the front-mounted configuration, the breakaway joints mount to the adapter arrangements in a first mounting position in which the breakaway joints are arranged to allow the breakaway boom segments to deflect in a deflection direction that is common with a direction faced by the sprayer facing side of the main boom body; and
wherein when the sprayer boom is in the rear-mounted configuration, the breakaway joints mount to the adapter arrangements in a second mounting position in which the breakaway joints are arranged to allow the breakaway boom segments to deflect in a deflection direction that is common with a direction faced by the outwardly facing side of the main boom body.

2. The breakaway adapter system of claim 1 wherein when converting the sprayer boom between front-mounted and rear-mounted configurations, the main boom body changes to an opposite orientation by rotating to face an opposite direction such that when the sprayer boom is in the front-mounted configuration, the sprayer facing side of the main boom body faces toward a front end of the spray and opposite a forward travel direction of the sprayer and when the sprayer boom is in the rear-mounted configuration, the sprayer facing side of the main boom body faces toward a back end of the spray and toward a forward travel direction of the sprayer.

3. The breakaway adapter system of claim 2 wherein when converting the sprayer boom between front-mounted and rear-mounted configurations, the breakaway joints maintain the same orientation when the sprayer boom is in either one of the front-mounted and rear-mounted configurations.

4. The breakaway adapter system of claim 3 wherein when converting the sprayer boom between front-mounted and rear-mounted configurations, the breakaway boom segments maintain the same orientation when the sprayer boom is in either one of the front-mounted and rear-mounted configurations.

5. The breakaway adapter system of claim 1 wherein each adapter arrangement further comprises an adapter plate having multiple adapter holes selectively receiving a fastener to define the first and second mounting positions of the adapter arrangements.

6. The breakaway adapter system of claim 5 further comprising a first hinge plate configured to allow deflection of the breakaway boom segment in a first direction, and a second hinge plate configured to allow deflection of the breakaway boom segment in a second direction, and wherein the first and second mounting positions of the adapter arrangements allow for mounting the first and second hinge plates.

7. The breakaway adapter system of claim 6 wherein each adapter plate has first and second adapter tabs with the first and second mounting holes extending through the respecting first and second tabs to selectively receive a fastener to provide the first and second mounting positions of the adapter arrangements.

8. The breakaway adapter system of claim 7 wherein the breakaway joints are supported by the first and second hinge plates.

9. The breakaway adapter system of claim 8 wherein,
the first hinge plate defines a left-side hinged hinge plate allowing the breakaway boom segment to deflect to the left when viewed from beyond the breakaway boom segment facing toward the breakaway joint, and
the second hinge plate defines a right-side hinged hinge plate allowing the breakaway boom segment to deflect to the right when viewed from beyond the breakaway boom segment facing toward the breakaway joint.

10. The breakaway adapter system of claim 9 wherein the left-side hinged and right-side hinged hinge plates include shock mounts extending upwardly from respective left and right portions that align with a corresponding one of the first and second adapter tabs of the adapter plate for connecting the left-side hinged and right-side hinged hinge plates to the adapter plates.

11. A breakaway adapter system for a sprayer boom having a pair of breakaway boom segments of an agricultural sprayer, wherein the agricultural sprayer is configured as one of a front-boom sprayer and a rear-boom sprayer, the breakaway adapter system comprising:
a pair of adapter arrangements that can mount in at least a first mounting position and a second mounting position,
wherein when the pair of adapter arrangements is in the first mounting position, the sprayer boom defines a front-mounted position for mounting the sprayer boom to a front-boom sprayer; and
wherein when the pair of adapter arrangements is in the second mounting position, the sprayer boom defines a rear-mounted position for mounting the sprayer boom to a rear-boom sprayer.

12. The breakaway adapter system of claim 11 wherein each adapter arrangement further comprises an adapter plate having multiple adapter holes that define the first and second mounting positions of the pair of adapter arrangements.

13. The breakaway adapter system of claim 11 wherein the sprayer boom includes a main boom body connected to the agricultural sprayer and with the main boom body having a sprayer facing side facing toward the sprayer and an outwardly facing side facing away from the sprayer,
wherein when the sprayer boom is in the front-mounted position, the sprayer facing side of the main boom body faces rearward toward the front-mounted boom sprayer; and
wherein when the sprayer boom is in the rear-mounted position, the sprayer facing side of the main boom body faces forward toward the rear-mounted boom sprayer.

14. The breakaway adapter system of claim 13 further comprising a pair of breakaway boom segments arranged outwardly beyond outer ends of the main boom body with the pair of adapter arrangements between the pair of breakaway boom segments and the main boom body,
wherein when the pair of adapter arrangements is in the first mounting position, the pair of adapter arrangements facilitates movement of the pair of breakaway boom segments in a deflection direction that is rearward and faces toward the front-mounted boom sprayer; and
wherein when the pair of adapter arrangements is in the second mounting position, the pair of adapter arrangements facilitates movement of the pair of breakaway boom segments in a deflection direction that is rearward and faces away from the rear-mounted boom sprayer.

15. The breakaway adapter system of claim 14 wherein a pair of breakaway joints is arranged between the main boom body and the pair of breakaway boom segments, wherein each breakaway joint of the pair of breakaway joints includes at least one hinge configured to allow movement of the respective breakaway boom segment relative to the main boom bod
