<p>The shaker device for a grape harvester, transmits transverse vibrations to the vines by means of two opposite rows of elastic pick-ups, which at one end, are connected to one of two supports which can pivot about a vertical axis. On their outer surface (15, 16) in the elastic region, the pick-ups (1, 2) have reinforcing elements (5, 6), whose ends are fixed to the pivotable supports (3, 4). The reinforcing elements are rigid and have a support face (13, 14), whose spacing from the outer face of the pick up increases positively towards the face end of the pick up because of a curvature, which is less than the maximum curvature of the deflected pick-up.</p> |
