Harvest machine for olive and similar fruits with adjustable fruit resonance vibration frequency

摘要

Machine for harvesting olive, almond, apricot, plum, mulberry, walnut, etc., shaking tree branches in the resonance frequencies of the fruit. The main feature of this embodiment is utilizing resonance phenomenon in effective harvesting of olives and similar products. Fruits' natural frequencies vary based on the extent of their ripeness, i.e. according to olive's condition (green, pink, black). Thus, olive tree is shaken with selected resonance frequency. The system has a flexible harvesting rod (2) controlled by the operator with an on-off power key (2b) and a wire mechanism lever (2a) for adjusting the jaws of a hook. The system further has a mobile electrical energy supply (4) and a three level resonance set button (5a). It is transported by a trolley or tripod (5) in order to carry the weight of the vibrating structure without exhausting the farmer.
