ABSTRACT:
In a separator for pneumatic single grade sowing machines, a supporting plate (1) is provided to which a plurality of fingers (8; 28; 41) are pivotally connected. One end of the fingers forms an effective area section (12) which engages passing seed grains clinging to suction holes (6) of an apertured plate 4. Each finger (8; 28; 41) is engaged by a respective spring (13; 20; 23; 30; 44) which acts on the fingers (8; 28; 41) and thus on their effective area sections (12) against the direction of rotation (10) of the apertured plate (4) (FIG. 1).
