System and method for actuating a boom assembly of an agricultural sprayer

1. A system for actuating a boom assembly of an agricultural sprayer, the system comprising:

a frame;

a boom assembly supported relative to the frame;

a linkage assembly configured to couple the boom assembly to the frame, the linkage assembly comprising:

a support arm pivotably coupled between the frame and the boom assembly,

a lift actuator pivotably coupled between the frame and the support arm, the lift actuator configured to raise and lower the boom assembly in a vertical direction, and

a tilt actuator pivotably coupled between the frame and the boom assembly, the tilt actuator configured to adjust a tilt angle of the boom assembly relative to the vertical direction; and

a controller configured to selectively actuate the tilt actuator to adjust the tilt angle of the boom assembly.

2. The system of claim 1 , wherein the controller is configured to adjust the tilt angle to an operational tilt angle during operation of the agricultural sprayer, the operational tilt angle corresponding to a substantially non-zero tilt angle relative to the vertical direction.

3. The system of claim 2 , wherein the operational tilt angle ranges from 5 degrees to 75 degrees relative to the vertical direction.

4. The system of claim 1 , wherein the boom assembly comprises a first boom section, a second boom section, and a fold actuator coupled between the first and second boom sections, the fold actuator configured to actuate the second boom section relative to the first boom section about a pivot axis.

5. The system of claim 4 , wherein the controller is configured to receive an input indicative of a change in a vertical positioning of the second boom section relative to a field reference position.

6. The system of claim 5 , wherein the controller is configured to control the operation of the tilt actuator to adjust the tilt angle of the boom assembly in a manner that tilts the pivot axis relative to the vertical direction, the controller being further configured to control the operation of the fold actuator to actuate the second boom section relative to the first boom section about the tilted pivot axis in a manner that moves the second boom section at least partially in the vertical direction to account for the change in the vertical positioning of the second boom section relative to the field reference position.

7. The system of claim 5 , wherein the input is received by the controller from at least one sensor configured to detect a parameter indicative of the vertical positioning of the second boom section relative to the field reference position.

8. The system of claim 7 , wherein the parameter comprises a vertical distance defined between the second boom section and the field reference position.

9. The system of claim 6 , wherein the controller is further configured to control the operation of the lift actuator to raise or lower the boom assembly in the vertical direction based on the change in the vertical positioning of the second boom section relative to the field reference position.

10. The system of claim 1 , further comprising a plurality of spray nozzles fixedly coupled to the boom assembly, wherein the controller is configured to adjust the tilt angle of the boom assembly to adjust a spray angle of the spray nozzles.
