<p>This machine makes it possible to suck up and cut the leaves of vines in the region of the bunches without wounding the grape, by means of linear sucking cutting heads (5 and 6) which automatically adapt to the vine by means of electric feelers which transmit information to a hydraulic unit in order to follow the slightest roughnesses of the vegetation. A conveyor belt (9) driven by hydraulic motor (17) and synchronised with the advancement makes it possible to avoid rubbing on the grapes. The leaf-removal heads are mounted on a parallelogram-type support (16) with thrust (20) continuously adjustable by means of a gas jack (15). The leaf-removal heads are mounted on a triple articulation (joint) (10, 11, 12) with gas dampers (shock absorbers) (19). A roller (14) is mounted at the front of the cutting bar for separating leaves and grapes. <IMAGE></p> |
