<p>The driving unit is set up on a support structure (6) and is activated by a rotary motion (B) generated by a disc (10), which is joined eccentrically to a plant distributor (15), linked to a connecting rod (14). The distributor (15) is provided with a wedge-shaped receptacle (115), with jaws (215), which receptacle (115) because of the eccentric movement (E-E') is wedged in and extracted from the soil. When it is wedged in, due to the contact with a cam (18), the jaws (215) open themselves (H), so that the plant coming from a supplying plate (11) and passing through a duct (12), from the receptacle (115) be put into the cavity prepared by the wedge. Then, the jaws (215) reclose themselves by a resilient self-recovery action. The connecting rod (14) is linked to the duct (12), so as the plants from the plate (11) arrive to the wedge-shaped receptacle (115), independently from the position of the eccentric movement of the distributor (15). <IMAGE></p> |
