摘要： A MOG limiting device, herein described as a MOG limiter, approximates a portion of the curvilinear length of a concave. The MOG limiting device can include a connection point near the middle of a concave, slightly offset from center. A bolt, washer and nut assembly protrudes downwardly from the underside of the concave. Two assemblies are positioned in the middle of each side of the concave. The assemblies cooperate with a mounting plate on the MOG limiters to form an upper concave connection and a lower concave connection in each half of the concave. In the cross frame, insert slots are positioned to receive a hinge point located at the end of each arced member making up the frame (rail supports). The hinge points are slidably inserted into the opening and then rotated upwardly to be positioned adjacent to and in conformity with the curvature of the underside of the concave with the connection assemblies holding the MOG limiter in place.

摘要： A threshing drum and a combine using a threshing drum are disclosed. The threshing drum comprising a drum body and beater bars. The beater bars each have a beating edge which describes a circumferential circle about a center axis of the drum body, on which the particular beating edge rotates about the center axis in a beating radius during operation of the threshing drum. To improve a flow of harvested material while the flow is being transferred from a threshing device to a downstream separating device, a cutting ring is positioned centrally on the drum body, viewed in the longitudinal direction of the drum body, which rotates in the circumferential direction of the drum body. The cutting ring has at least one circumferential cutting edge which describes a circumferential circle whose cutting radius, measured with respect to the center axis, is greater than the beating radii of the beating edges.

摘要： An agricultural harvester includes a threshing system having a rotor, a rotor cage surrounding the rotor and including a concave, and a transition cone defining an infeed to the rotor cage. The transition cone has a conical inner surface extending in an axial direction between an upstream end and a downstream end of the cone. A vane is mounted to the conical inner surface of the transition cone. The vane protrudes radially from the conical inner surface, and extends along an axial direction between the upstream end and the downstream end. The vane has a body extending along an axis and a cross-sectional shape that is not constant along the axis.

摘要： An agricultural vehicle includes a chassis, a threshing and separating mechanism supported by the chassis and configured for threshing and separating a crop material, a cleaning system positioned downstream of the threshing and separating mechanism in a direction of crop material flow, and an auxiliary processing system positioned downstream of the threshing and separating mechanism in the direction of crop material flow. The auxiliary processing system has an inlet and an outlet, and includes a discharge chopper having an end and a first direction of rotation about an axis of rotation. The auxiliary processing system also includes at least one rethreshing element coaxially aligned with the discharge chopper and adjacent to the end of the discharge chopper and having a second direction of rotation opposite to the first direction of rotation of the discharge chopper.

摘要： A concave segment (6) for combine harvesters (1), which is provided for separating harvest (2), extends in a circumferential direction (65) in a curve about a concave axis (53), and includes numerous finger strips (62). The finger strips (62) each have a transverse strip (67), wherein the transverse strips (67) each extend in a direction of extension parallel to the concave axis (53), and wherein numerous fingers (63) are disposed on each of the transverse strips (67). The fingers (63) have a curved cross section thereby, and/or the transverse strips (67) have a wave shape (74) in the direction of extension (70).

摘要： A locking arrangement for a concave of a rotary combine, the concave having first and second ends spaced circumferentially around a rotor of the combine. The first end includes a pivot member received in an opening of a hook member supported by a support structure so as to support the first end for pivotal movement about a first pivot axis substantially parallel to a longitudinal axis of rotation of the rotor. A locking member mounted on the hood member is pivotable between an engaged position for engaging the pivot member of the first end of the concave for retaining the pivot member in the opening of the hook member and a disengaged position wherein the locking member is disengaged from the pivot member while the pivot member is supported in the opening by the hook member.

摘要： A combine harvester comprises a threshing and separating mechanism mounted to a main frame, which includes a generally cylindrical chamber having a generally longitudinal axis, and a separating concave assembly. The arrangement further includes a rotor assembly mounted for rotation in the chamber and comprising a generally cylindrical rotor body with a separating section associated with the separating concave assembly. The separating mechanism further comprises a beater assembly arranged behind the concave assembly for receiving threshed and separated crop material therefrom and projecting it rearwardly. The beater assembly comprises a transverse guide mounted behind the separating concave assembly and below the rotor body, and a transverse beater rotor. The chamber comprises a curved guide plate arranged behind the separating concave assembly and above the guide. This guide plate distributes the separated crop material over the full width of the guide in order to minimize the chance that material starts accumulating in the one or other corner and the separating system gets plugged.
