<p>The apparatus for harvesting crops, particularly seed crops, comprises a mobile support structure (20) and a crop stripping device in the form of a rotor (30), which may be attached to height adjustable arms and is driven by drive means (22). The rotor (30) carries transverse rows of wedge form crop stripping elements (10) which may be combined with transverse ribs. The crop stripping elements have prominent leading edges, for example each formed at the junction between two faces which are acutely inclined with respect to each other. They may be attached to removable, raised, hollow mounting bars. The drive to the rotor may be so arranged that during forward movement of the apparatus the crop engaging elements (32) are propelled progressively through the crop, moving upwards at a front region. Seeds and other plant parts detached by the action of the rotor are impelled into a crop flow passage (27) under a crop guide cover (21). Essential dimensions of the rotor and crop engaging elements may be varied conveniently.</p> |
