ABSTRACT:
A vacuum operated fruit harvesting machine is disclosed for harvesting fruit from fruit trees. The fruit harvesting machine of the invention comprises a picker head connected to an air flow control valve. A discharge valve is connected to the air flow control valve by means of a plurality of rigid or flexible conduits. The picker head comprises a conduit having an internal wall portion. A gripper is angularly positioned relative to the internal wall of the curved conduit for gripping the stem of the fruit. As the fruit is conducted into the picker head, the fruit pivots against the internal wall which functions as a fulcrum causing the stem to be peeled away from the fruit at the calex thereof. The air control valve in an alternative embodiment is a gate valve apparatus in which an increase in differential pressure between an intake chamber and a differential means controls the gate valve to move the gate valve from a second position to a first position for permitting transportation of the fruit towards a source of partial vacuum.
