  • Patent number: 4825582
    Abstract: A vacuum apparatus is disclosed for mechanically removing and destroying insects and related pests from low growing crops. In the preferred embodiment, the apparatus is affixed to a three-point hitch and power takeoff of a standard farm tractor and comprises a dual fan assembly connected by forced air ducts and suction hoses to a plurality of suction shoes. One of the fans forces air through ducts to individual intakes on the shoes, where the air is directed through manifolds down to oppositely aligned blast channels on the lower edges of plant tunnels. These channels lead the forced air current up toward pest receiving outlets in the top center of the interior of each tunnel. Suction hoses, leading from the other fan, apply a partial vacuum to expansion compartments located directly above the pest receiver outlets.In operation, the eradictor is lowered over parallel rows of plants until the plant tunnels enclose subject plants.
