Abstract: A clean out system of a header for an agricultural vehicle including at least one cover having a plurality of perforations and at least one actuating member connected to the at least one cover. The at least one actuating member is configured for moving the at least one cover between a first position to completely cover at least one cutout of the frame of the header for blocking the unwanted material from exiting the header, a second position to at least partially uncover the at least one cutout for permitting the unwanted material to pass through the at least one cutout, and a third position to align at least one perforation of the plurality of perforations with the at least one cutout for permitting the unwanted material to pass through the at least one cutout and the at least one perforation of the plurality of perforations.

Abstract: A cleaning system of a header for an agricultural vehicle. The header includes a frame with a floor having at least one cutout therein. The cleaning system includes at least one door, an elongated member operably connected to the at least one door, and at least one actuator connected to the elongated member. The elongated member is rotatable by the at least one actuator to slide the at least one door between a first position for covering the at least one cutout and a second position for at least partially uncovering the at least one cutout and allowing an unwanted material to pass through the at least one cutout.

Abstract: A threshing section for a combine harvester includes a rotor and a transition cone. The rotor has an axis of rotation, a downstream end, and an upstream end. The upstream end includes one or more blades for moving crop downstream in a direction of crop flow. The transition cone at least partially surrounds the upstream end of the rotor and the blades. An annular space is formed between a swept profile of the blades and an interior surface of the transition cone through which crop is introduced into the threshing section. A cross-sectional area of the annular space, which is measured in a radial direction, is substantially constant along at least a portion of a length of the swept profile.

Abstract: A threshing system of an agricultural harvester includes a rotor cage surrounding a rotor, a threshing space defined between the rotor cage and the rotor, and a transition cone defining an infeed to the rotor cage and the threshing system. A mating interface between the rotor cage and the transition cone is curved in three different dimensions of a Cartesian coordinate system for maximizing the threshing space. As viewed from above the mating interface of the threshing system, a convex portion of the rotor cage is mounted to a concave portion of the transition cone.

Abstract: A threshing and separating system including a rotor cage, a first vane rail movably connected to the rotor cage, and a first vane portion with a first constrained end pivotably connected to the rotor cage and a first movable end linked to the first vane rail. The threshing and separating system further including a second vane rail movably connected to the rotor cage, and a second vane portion with a second constrained end pivotably connected to the rotor cage and a second movable end linked to the second vane rail, the second vane portion and the first vane portion together define a substantially continuous vane.

Abstract: An agricultural vehicle including a chassis and a threshing system supported by the chassis. The threshing system includes a rotor, a housing surrounding at least a portion of the rotor and including at least one concave, and a concave adjustment and suspension device connected to the housing and configured for adjusting a position of the concave frame and relieving an impact force acting on the at least one concave. The concave adjustment and suspension device includes a torsion bar, a drive operably coupled to the main section of the torsion bar and configured for rotating the torsion bar to adjust the position of the concave frame, and at least one pneumatic spring mounted to the torsion bar and configured for compressing to relieve the impact force acting on the at least one concave.

Abstract: A draper belt system is provided that includes a first draper belt assembly with first and second rollers, and a second draper belt assembly with third and fourth rollers. The third roller of the second draper belt assembly is disposed adjacent to the first roller of the first draper belt assembly. The first draper belt assembly is configured to pivot relative to the second draper belt assembly. Pivoting of the first draper belt assembly results in a change in a distance between the first and third rollers.
