Abstract: An apparatus for separating a granular material from a conveying air stream (5) comprising a deflecting surface (2) for the laden conveying air stream (5) against which flow may take place substantially tangentially is described. In order to allow advantageous separation conditions, it is proposed that the deflecting surface (2) adjoins a guiding surface (3) curved in the opposite direction in the flow direction for a largely laminar flow separation.

Abstract: A straw walker for a combine harvester includes a straw walker grate provided with through-openings for grain to be separated and with driving profiles arranged along the straw walker grate at a mutual distance from one another. The driving profiles extend transversely to the conveying direction and include a first respective profile limb upwardly protruding from the straw walker grate. In order to provide advantageous conveying conditions, the driving profiles also include a second respective profile limb descends in the conveying direction towards the straw walkers grate. The second respective profile limb is provided between the first respective profile limb and the straw walker grate on the breast side of the driving profiles. The breast side of the driving profiles is at the rear of the driving profiles in the conveying direction.

Abstract: The invention describes a straw walker for a combine harvester, comprising a straw walker grate (2) provided with through-openings (3) for the grain to be separated and with driving profiles (5, 6) which are arranged along the straw walker grate (2) at a mutual distance from one another, which extend transversely to the conveying direction and which comprise a profile limb (7) upwardly protruding from the straw walker grate (2). In order to provide advantageous conveying conditions it is proposed that a profile limb (8) descending in the conveying direction towards the straw walkers grate (2) is provided between the profile limb (7) upwardly protruding from the straw walker grate (2) and the straw walker grate (2) on the breast side of the driving profiles (5, 6) which is at the front in the conveying direction.
