  • Patent number: 5319911
    Abstract: A machine for harvesting foodstuffs, such as nuts from the ground, uses compressed air passing through at least one venturi to create a vacuum at the inlet of a pickup conduit. Nuts are sucked into the pickup conduit which provides a straight flow path for the nuts. Compressed air is also discharged near the pickup conduit inlet to blow nuts to the inlet of the pickup conduit. Additionally, the machine discharges air from laterally extending blower arms to move nuts from obstacles which cannot be easily reached by the pickup conduit to locations where the foodstuffs can be reached by the pickup conduit.
