HARVESTING DEVICE COMPRISING FLEXIBLE LINKS FOR A MACHINE FOR HARVESTING FRUITS, BERRIES AND THE LIKE

摘要

A harvesting device comprises two shaker assemblies (5) mounted face-toface on a straddle carrier frame (9) for shaking fruit-bearing trees or bushes. Each shaker assembly comprises a plurality of horizontal flexible material rods (22) having a first end (22a) detachably fixed to an oscillatory vertical support (19), a median portion (22c) adapted to act on the fruit-bearing trees or shrubs to shake them, and a second end (22b) connected to the frame (9) by a connecting link (23) that is grosso modo horizontal and perpendicular to a vertical median plane of symmetry of the frame. Hence, in operation, the second end (22b) of the rod (22) is maintained at a substantially constant distance from the vertical median plane of symmetry. The connecting link (23) is fixed to the frame (9) by a rigid connection (41) and is flexible in a substantially horizontal plane, so that, in operation, the end (23a) of the connecting link (23) adjoining the rod (22) moves to-and-fro substantially horizontally in a direction substantially parallel to the vertical median plane of symmetry.
