A transition cone for a threshing system of an agricultural harvesting machine has an inner surface with a tapering inner circumference between a wider upstream end and a narrower downstream end, and a plurality of vanes in the transition cone. Each vane extends between the upstream end and the downstream end and at least partly around the tapering inner circumference. Each vane includes an upstanding segment extending away from the inner surface, and a base segment extending from the upstanding segment along the inner surface on the downstream side of the upstanding segment. The base segment has a thicker proximal region adjacent the upstanding segment and a thinner distal edge opposite thereto.

An agricultural vehicle including a chassis and a threshing system supported by the chassis. The threshing system includes a rotor, a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor, and an infeed ramp connected to the front concave. The infeed ramp is located at a distance radially away from the rotor and has a plurality of slots therein. The threshing system also includes a support member positioned underneath the infeed ramp and a plurality of vanes connected to the support member. Each vane extends through a respective slot of the plurality of slots and is located at a distance radially away from the rotor. The vanes are configured for contacting and directing the crop material rearwardly towards the front concave.

A threshing and separating system including a non-stationary rotor cage including a perforated cylindrical body extending in a longitudinal direction from a first open end portion to a second open end portion. The first open end portion supported by a first rotatable coupling point, and the second open end portion supported by a second rotatable coupling point. The threshing and separating system also includes a rotor configured to rotate within the non-stationary rotor cage to thresh harvested crop. The non-stationary rotor cage is configured to rotate about an axis extending between the first rotatable coupling point and the second rotatable coupling point, and to be rotationally driven by the rotor via the threshed harvested crop.

A transition cone for a threshing system of an agricultural harvesting machine has an inner surface with a tapering inner circumference between a wider upstream end and a narrower downstream end, and a plurality of vanes in the transition cone. Each vane extends between the upstream end and the downstream end and at least partly around the tapering inner circumference. Each vane includes an upstanding segment extending away from the inner surface, and a base segment extending from the upstanding segment along the inner surface on the downstream side of the upstanding segment. The base segment has a thicker proximal region adjacent the upstanding segment and a thinner distal edge opposite thereto.

A threshing system for an agricultural harvester includes a rotor and a substantially cylindrical cage that surrounds at least a portion of the rotor. The threshing system also features a material flow adjustor for controlling axial movement of material through the cage. The material flow adjustor is movably mounted adjacent to a threshing space and includes at least one material conveying edge that enters the threshing space. The material flow adjustor is moveable between a first operative position, in which the at least one material conveying edge is spaced from the rotor in a radial direction by a first distance, and a second operative position in which the at least one material conveying edge is spaced from the rotor in the radial direction by a second distance, the second distance being less than the first distance.
