Classifying and enclosing device for a stone swath former drawn by a tractor, of the type having two axes forming a 'V' with respect to the direction of motion of the tractor, and having resilient and vibratable teeth
The present invention relates to a classifying and enclosing device for a stone swath former, having oblique arms deployed in a V-shaped manner and equipped with vibrating teeth juxtaposed in the form of a comb, characterised in that at least one bar (13) or a series or shorter bars (13) placed longitudinally in succession is arranged outside the row of vibrating teeth (5) carried by each arm (2), in a direction substantially parallel to the direction of this arm (2) and at a height relative to the ground (7) which, together with the mutual spacing of the teeth (5), determines the maximum size of the stones capable of escaping laterally outside the "V", after being raked up upstream of the swath former (1). The device according to the invention can be used in the sector of the removal of stones from stony ground, the stone swaths obtained having a uniform composition making it easier to pick them up or crush them on the spot.
