ABSTRACT:
A fruit harvesting machine consisting of a wheeled support on which is mounted a vertically extending housing containing a pair of transversely arranged blowers, one above the other, the housing having a laterally directed, vertically extending, laterally converging air collection chamber receiving air from the blowers and having a laterally facing discharge passage of substantial height. Movable air-guiding members are mounted in the discharge passage in a vertical array. In one embodiment, the members are louvers horizontally pivoted and linked together for simultaneous oscillating movement. Another embodiment uses a vertical crankshaft and drive linkages to oscillate the louvers. A further embodiment uses vertically pivoted oscillating louvers coupled by gears. A still further embodiment uses vertically journaled rotating apertured drums cooperating with an apertured fixed outlet wall on the mouth of the discharge passage to control the lateral discharge of the high pressure air from the discharge passage. Another embodiment employs inclined air-guiding discs mounted on a vertical rotating shaft. In each case, the lateral air discharge is of an intermittent nature tending to cause shaking or oscillation of a tree to cause fruit thereon to break loose from the tree as the machine is moved therepast.
