Abstract
An agricultural system includes a header comprising a gauge wheel and a frame, in which the gauge wheel and the frame are coupled to a hydraulic cylinder that is configured to adjust the gauge wheel relative to the frame. The agricultural system also includes a hydraulic circuit fluidly coupled to the hydraulic cylinder, in which the hydraulic circuit is configured to control a fluid flow into and out of the hydraulic cylinder to adjust the gauge wheel relative to the frame, and the hydraulic circuit includes an accumulator configured to enable an amount of fluid in the hydraulic cylinder to change during a harvesting operation of the agricultural system such that the gauge wheel may oscillate from a set position during the harvesting operation.
Claims17
An agricultural system, comprising:
- a header comprising a gauge wheel and a frame, wherein the gauge wheel and the frame are coupled to a hydraulic cylinder that is configured to adjust the gauge wheel relative to the frame;
- a first hydraulic circuit fluidly coupled to the hydraulic cylinder, wherein the first hydraulic circuit is configured to control a fluid flow into and out of the hydraulic cylinder to adjust the gauge wheel relative to the frame, and the first hydraulic circuit comprises an accumulator configured to enable an amount of fluid in the hydraulic cylinder to change during a harvesting operation of the agricultural system such that the gauge wheel may oscillate from a set position during the harvesting operation;
- and
- a second hydraulic circuit, a fluid reservoir, and a valve, wherein the valve is configured to selectively enable the fluid to flow between the fluid reservoir and the first hydraulic circuit while the valve is in a first position and between the fluid reservoir and the second hydraulic circuit while the valve is in a second position.
A hydraulic system for an agricultural system, the hydraulic system comprising:
- a hydraulic cylinder comprising a rod coupled to a gauge wheel of the agricultural system, wherein the hydraulic cylinder comprises a first section and a second section;
- a fluid reservoir;
- a valve configured to transition between a first position and a second position, wherein the valve is configured to enable a fluid to flow between the fluid reservoir and the first section of the hydraulic cylinder while the valve is in the first position to adjust a position of the rod, and the valve is configured to block the fluid from flowing between the fluid reservoir and the first section of the hydraulic cylinder while the valve is in the second position;
- a first accumulator configured to receive the fluid from or supply the fluid to the first section of the hydraulic cylinder regardless of the position of the valve;
- and
- a second accumulator configured to receive the fluid from or supply the fluid to the second section of the hydraulic cylinder regardless of the position of the valve.
An agricultural system, comprising:
- a header comprising a gauge wheel and a frame;
- and
- a hydraulic system, comprising:
- a hydraulic cylinder coupled to the gauge wheel and to the frame;
- a fluid reservoir;
- a first hydraulic circuit fluidly coupling the fluid reservoir with the hydraulic cylinder;
- and
- a second hydraulic circuit fluidly coupling the fluid reservoir with another component of the agricultural system;
- a valve configured to selectively enable fluid to flow between the fluid reservoir and the first hydraulic circuit while the valve is in a first position and between the fluid reservoir and the second hydraulic circuit while the valve is in a second position;
- and
- a control system communicatively coupled to the valve, the control system is configured to instruct the valve to transition to the first position to transition the hydraulic system to a first configuration, the control system is configured to instruct the valve to transition to the second position to transition the hydraulic system to a second configuration, the hydraulic system is configured to enable the fluid to flow between the fluid reservoir and the first hydraulic circuit while the hydraulic system is in the first configuration to change a respective position of the gauge wheel relative to the frame, and the hydraulic system is configured to enable the fluid to flow between the fluid reservoir and the second hydraulic circuit in the second configuration to change a respective position of the other component.
