Abstract
An agricultural system includes an arm of a header. The arm is configured to rotate about a pivot joint. The agricultural system also includes a fluid-filled biasing member, an actuator, and a controller. The fluid-filled biasing member is configured to couple to the arm and to impart a torque onto the arm. The actuator is coupled to the fluid-filled biasing member and is configured to move the fluid-filled biasing member relative to the actuator to change the torque imparted by the fluid-filled biasing member onto the arm. The controller configured to receive an input indicative of a target flotation pressure of the arm output a signal to instruct the actuator to set a position of the fluid-filled biasing member relative to the actuator based at least in part on the target flotation pressure of the arm.
Claims20
An agricultural system, comprising:
- an arm of a header, wherein the arm is configured to support a cutter bar assembly, and the arm is configured to rotate about a pivot joint;
- a fluid-filled biasing member configured to couple to the arm, wherein the fluid-filled biasing member is configured to impart a torque onto the arm;
- an actuator coupled to the fluid-filled biasing member, wherein the actuator is configured to move the fluid-filled biasing member along the arm relative to the actuator to change the torque imparted by the fluid-filled biasing member onto the arm;
- and
- a controller configured to:
- receive an input indicative of a target flotation pressure of the arm;
- and
- output a signal to instruct the actuator to set a position of the fluid-filled biasing member relative to the actuator based at least in part on the target flotation pressure of the arm.
A non-transitory computer readable medium comprising executable instructions that, when executed by a processor, are configured to cause the processor to:
- receive an input indicative of a target flotation pressure of an arm of a header for an agricultural system, wherein the arm is coupled to a support of a fluid-filled biasing member of the header and configured to rotate about a pivot joint, the fluid-filled biasing member is configured to impart a torque onto the arm, and the support of the fluid-filled biasing member is coupled to an actuator configured to move the support along the arm relative to the pivot joint;
- and
- output a signal to instruct the actuator to set a position of the support of the fluid-filled biasing member relative to the pivot joint based at least in part on the target flotation pressure of the arm.
A header of an agricultural system, comprising:
- a cutter bar assembly configured to cut crops during operation of the agricultural system;
- an arm assembly comprising:
- an arm configured to support a portion of the cutter bar assembly,
- wherein the arm is configured to rotate about a pivot joint;
- a fluid-filled biasing member comprising a support configured to couple to the arm, wherein the fluid-filled biasing member is configured to impart a torque onto the arm;
- and
- an actuator comprising a rod configured to couple to the support, wherein the actuator is configured to move the support along the arm relative to the pivot joint to change the torque imparted by the fluid-filled biasing member onto the arm;
- and
- a controller communicatively coupled to the arm assembly and configured to:
- receive an input indicative of a target flotation pressure of the arm;
- and
- output a signal to instruct the actuator to set a position of the support relative to the pivot joint to set a current flotation pressure of the arm based at least in part on the target flotation pressure of the arm.
