Abstract:
A threshing and separating mechanism for a combine having a supporting structure, the mechanism comprising:an elongated rotor mounted in the supporting structure for rotation about a rotor axis; an elongated housing mounted in the supporting structure and surrounding the rotor, the housing being spaced from the rotor to form an annular space between the rotor and the housing for crop material to flow through in a crop flow direction from an inlet end of the housing to an outlet end of the housing; and the housing, when viewed in a vertical section along a housing axis, being frusto-conical, having a top that diverges from a bottom in the crop flow direction, and the housing being arranged relative to the rotor such that the gap between the rotor and the top of the housing increases in the crop flow direction, the housing axis diverging upwardly away from the rotor axis in the crop flow direction.
