Abstract:
A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester. One embodiment has draper assemblies and a central conveyor fixed relative to the flexible cutterbar assembly, while another has the draper assemblies and central conveyer flexible with the cutterbar assembly.
Abstract:
A combine harvester where opposing concaves on either side of a rotor of a processing system substantially simultaneously travel symmetrical paths. The concaves of the processing system may be pivotally supported on a rockshaft where the axis of the rockshaft moves in a generally vertical manner so that the concaves then move generally radially toward or away from the rotor.
Abstract:
A combine harvester where opposing concaves on either side of a rotor of a processing system substantially simultaneously travel symmetrical paths. The concaves of the processing system may be supported on a suspension system such that the concaves are pivotally supported from a common axial location at one end and translationally adjusted at another end to move the concaves generally radially toward or away from the rotor.
Abstract:
A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester. The header includes laterally spaced support arms attached to and cooperatively supporting the flexible cutterbar assembly. The support arms are pivotally coupled to the frame for swinging movement about a laterally extending axis so that the cutterbar assembly is operable to flex along the length thereof in response to changes in terrain as the header is advanced.
Abstract:
A counterbalancing epicyclic sickle drive has a pair of oppositely rotating weights that offset the inertial forces of the sickle during its abrupt acceleration and deceleration at opposite ends of its path of travel. One of the weights rotates with the main shaft of the drive about its longitudinal axis, while the second weight is fixed to an oppositely rotating crankshaft that orbits about the axis of the main shaft in eccentric relationship thereto. The weight on the main shaft is heavier than the weight on the crankshaft so as to offset changes in inertial forces produced by the crankshaft weight during increased acceleration of its center of gravity at opposite ends of its elliptical path of travel about the axis of the main shaft.
Abstract:
A duct may be disclosed. The duct may comprise a wall and a cover. The wall may define a passage, an inlet in fluid communication with the passage, an outlet in fluid communication with the passage, and an opening in fluid communication with the passage. The cover may be arranged to selectively block the opening.
Abstract:
A harvesting header includes a header frame, a cutterbar assembly mounted to the header frame, and a conveyor assembly supported behind the cutterbar assembly to receive crop severed by the cutterbar assembly. The conveyor assembly includes a pair of side conveyors and a fore-and-aft draper located between the side conveyors. The header further includes a central crop-conveying member that overhangs the rear margin of the fore-and-aft draper and a floor pan that at least partly defines a transition area. The floor pan presents a forwardmost edge adjacent to and rearward of the rear margin. The forwardmost edge is located above a lower run of the draper to direct severed crop materials from the upper run of the draper and to facilitate crop material flow through the transition area.
Abstract:
A curved stripper plate for a row unit of a harvesting header. The stripper plate removes useable parts from crop stalks gathered in a crop passage. In one embodiment, the stripper plate is arched thereby providing an upwardly curved edge along a crop passage of the row unit.
Abstract:
A harvesting header includes a header frame, a flexible cutterbar assembly, and a plurality of laterally spaced apart support arms that are attached to and cooperatively support the flexible cutterbar assembly. The header also includes a draper assembly with a side draper carried on multiple ones of the support arms so as to flex with the cutterbar assembly. The side draper includes an endless flexible draper belt presenting laterally endmost margins, with upper and lower crop-conveying runs extending between the margins. The header further includes pivoting structure mounted relative to the header frame at a rear pivot location so that the pivoting structure projects forwardly from the rear pivot location.
