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