Apparatus for individual separation of small bodies, which is of application in precision sowing machines, comprising a frame (1) at the top of which a block-piece (4) is articulated, which block-piece comprises a rank of boxes (6) into which through respective loading mouth-pieces (7), seeds (8) are supplied in suitable amounts, said block-piece comprising in a forward area a rank of conical cavities (9) corresponding to boxes (6), said cavities being formed by two plates (10, 11) provided with semi-conical entrances (9a, 9b) which are opposite in a position of the plates wherein they are applied one against the other, which conical cavities due to the oscillation of the block-piece from a position inclined rearwardly to a position inclined forwardly under the action of suitable means, fill with seeds, then said means determine the oscillation of the block-piece rearwardly.
