Abstract
A rotor housing assembly for a harvester has at least one cover plate forming part of a generally cylindrical shaped rotor housing, a central longitudinal axis, and an inner surface, which, when mounted, faces the central longitudinal axis and has a first radius, and one or more rotatable vanes which each are rotatably mounted on an inner surface of the cover plate facing the central longitudinal axis at a rotation point. The one or more rotatable vanes have a contact surface with the inner surface. The contact surface has a second radius that is larger than the first radius of the cover plate. The inner surface of the top cover plate, per rotatable vane, has a symmetrically curved shape such that, during a rotation of the respective vane, the contact surface of the vane with the inner surface of the cover plate substantially follows the shape of the inner surface.
