Abstract: A crop stripper has a moving shaker pan between the stripper drum and an auger receiving the gathered crop parts from the drum. The pan has a conveying platform arranged in a series of descending steps from the stripper drum to the auger. It is constrained to oscillate in a manner in which the front end has both horizontal and vertical components of movement whereas the rear end moves along a small downwards incline. It is found that these features help to promote the rearward movement of crop parts such as grain, so reducing spillage in the space between the stripper drum and the auger.

Abstract: Crop stripping apparatus is provided comprising a toothed crop-stripping drum and an auger for collecting crop stripped by the drum. Between the drum and the auger is a roller rotatable in the same direction as the drum. Behind and close to the outer peripheral surface of the roller a chute slopes downwards towards the auger at a progressively reducing angle. The spacing between the drum and the auger is greater than the expected length of deteched plant stalks but is otherwise kept as small as possible for compactness. The roller serves to draw the plant stalks from the drum and urge them into the zone of action of the auger.

Abstract: A crop stripper has at least one drum (6a, 6b) with several axially extending series of stripping teeth (8). The drum is rotatably in end supports. The tooth roots (26) at the ends of the drum have an edge profile inclined radially away from the adjacent supports to deflect plant stems which contact these profiles during the operation of the stripper away from the supports, so reducing the tendency for the stems to become trapped between rotor and support. A capping (32) on the support overlaps the adjacent tooth roots to assist this effect. A pair of drums can be arranged end to end with an intermediate support (14) between them and be similarly arranged to deflect plant stems away from the intermediate support. This allows increase of the operating width of the crop stripper while minimizing the risk of blockage from stems trapped between the intermediate support and the drums.

Abstract: A crop stripper drum has a series of axial rows of flexibly displaceable teeth (12) circumferentially spaced around the drum. At the roots of the teeth are bulbous openings (12b, 22a) formed in metal members, which may comprise the teeth (12) or be elements (21) separate therefrom. For flexibility, the teeth may be given root openings larger than the openings formed by said separate elements, thereby reducing their root widths, or they may be put in a resilient mounting (62) that increases the deflection they experience under load. Separate elements (52) provided for forming the stripper openings, may be of an adjustable form to vary the width of the openings. The constructions disclosed are able to allow the use of metal for the active stripping means, whereby to increase the service life and reduce the power requirements. Adjustment of the size of the openings allows the striper to be adapted to harvest different crops.
