<p>In a separator for pneumatic single grain sowing machines, a supporting plate is provided to which a plurality of fingers are pivotally connected. One end of the fingers forms an effective area section which engages passing seed grains clinging to suction holes of an apertured plate. Each finger is engaged by a respective spring which acts on the fingers and thus on their effective area sections against the direction of rotation of the apertured plate.</p> |
