INTEGRATED LIFT AND FRAME LOCK FOR A FOLDING CORN HEAD ROW SEPARATOR
20200214206 · 2020-07-09 ·

A harvester or combine includes a folding corn head with a center section and folding wing sections. A folding row separator cover at the hinge location of the folding head sections folds to an angled position so that the folding action between the wings and the center section is not impaired. A single assembly actuates the folding of the row separator as well as locking and unlocking of the wing sections relative to the center frame section. A hydraulic cylinder actuates a main link that connects to the row separator cover and also to a lock pin. Actuation of the hydraulic cylinder pulls the extended end of the main link rearward and upward to raise the cover. The same motion also pulls the locking pin forward from engagement. Retraction of the hydraulic cylinder rod lowers the extended end of the frame of the main link and pulls the cover downward while also moving the lower portion of the main link rearward to engage the locking pin with the frame.

CORN HARVESTER

A harvester includes a main frame, first side frame, and a second side frame. The first and second side frames are rotatable about the main frame between a deployed position and a stowed position. A first crop divider is rotatable with respect to the first side frame to change an angle between the first crop divider and the ground. A first biasing member biases the first crop divider into the raised position. A second crop divider is rotatable with respect to the second side frame to change an angle between the second crop divider and the ground. A second biasing member biases the second crop divider into the raised position. During movement of the first and second side frames into the stowed position, the first and second crop dividers are moved into the lowered position against the biasing force of the respective biasing member.

Harvester head reel segments synchronization

A harvester head may include a position adjustable reel having a first segment and a second segment, a hydraulic supply comprising a pump and a reservoir, a first plurality of hydraulic cylinders coupled to the first segment to reposition the first segment, a second plurality of hydraulic cylinders coupled to the second segment to reposition the second segment, a first bidirectional valve operably coupled between the hydraulic supply and the first plurality of hydraulic cylinders, a second bidirectional valve operably coupled between the hydraulic supply and the second plurality of hydraulic cylinders, at least one sensor to sense relative positioning of the first segment and the second segment and a controller. The controller may output control signals to the first bidirectional valve and the second bidirectional valve based upon signals from the at least one sensor to synchronize positioning of the first segment and the second segment.

SYSTEM AND METHOD FOR GROUND FOLLOWING OF A COMBINE HEADER WITH FLEXIBLE CUTTER BAR

A harvesting head for a combine and method of operating. An attachment frame at an aft end of the head attaches with a combine feederhouse. A main frame of the head is movably connected to the attachment frame, and the main frame has a range of travel with respect to the attachment frame. A resilient float element is provided between the attachment and main frames. A flexible cutterbar on the main frame operates to cut crops. The cutterbar is supported on the main frame by a plurality of pivoting arms distributed across a width of the head. With the main frame in a nominal intermediate position within the range of travel, the plurality of pivoting arms have 10 percent or less of total available travel as upward travel and at least 90 percent of total available travel as downward travel when the head is set in the nominal position.

Folding agricultural head

A head for an agricultural machine includes a frame with a center segment defining a first longitudinal axis and a wing defining a second longitudinal axis. The head also includes a motion control assembly connecting the center segment and the wing such that the wing is movable relative to the center segment between a deployed position and a non-deployed position. The motion control assembly is configured to maintain the second longitudinal axis in a parallel relationship with the first longitudinal axis as the wing moves between the deployed position and the non-deployed position, and the wing is movable from the deployed position to the non-deployed position along a continuous arc.

WING LOCKING WITH HYDRAULIC BLOCKER VALVE

A harvesting system includes a header pivotably attached to a combine. The header includes a center section to which a left wing and right wing are pivotably attached. A wing locking system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially fiat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

ORIFICED CHECK VALVE IN WING CIRCUIT

A wing locking system for a harvesting header is provided. The wing locking system includes an accumulator, a fluid cylinder operably attached to a wing of the harvesting header, a hose fluidly connecting the accumulator and the fluid cylinder, and a valve operably disposed between the accumulator and the fluid cylinder. The valve includes a first selectable position configured to permit a first fluid flow rate between the accumulator and the fluid cylinder and a second selectable position configured to permit a second fluid flow rate from the accumulator to the fluid cylinder. The first fluid flow rate is greater than the second fluid flow rate.

Harvesting head constant force assembly
10524422 · 2020-01-07 · ·

An agricultural harvesting head for an agricultural harvester has a constant force assembly that changes the mechanical advantage of a spring applied to the mainframe of the agricultural harvesting head. As the mainframe of the agricultural harvesting head moves up and down on the front of the combine feederhouse, compressing and decompressing the spring, the constant force assembly changes the mechanical advantage of the spring such that the spring provides a relatively constant lifting force to the mainframe of the harvesting head as the mainframe moves up and down.

SUSPENSION COMPLIANCE TO REDUCE FRAME LOADING

A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.
