  • Patent number: 5768822
    Abstract: A tractor mountable apparatus for collecting and destroying insects from multiple rows of plants, and for simultaneously burning unwanted vegetation on the ground between the rows of plants as the tractor passes along the rows, is disclosed. The apparatus includes a supporting frame mountable upon the front end of a tractor with a number of open top metal pans suspended from the supporting frame at spaced intervals such that the pans pass between rows of plants as the apparatus moves through a field. Each of the pans has three or more transversely spaced elongated gas burner conduits for directing combustible gases along the surface of the pan and directing the combustible gases downwardly beyond the rear end of the pan for destroying insects that are knocked into the pan as the pan passes between the rows, and for destroying unwanted vegetation between the rows of plants.

  • Patent number: 4148150
    Abstract: Tractor mountable apparatus for collecting and destroying insects from multiple rows of plants, such as cotton, as the tractor passes along the rows is disclosed. The apparatus comprises a supporting frame including longitudinal support members mountable upon the front end of a tractor to project forward rather than rearwardly thereof, and transverse support members carried by the longitudinal support members. A plurality of insect destroying open topped metal pans are suspended from the transverse support members and are spaced to pass between the rows of plants as the apparatus moves through a field. Each of the pans has an elongated perforated gas fired burner for heating the pan and for completely incinerating insects falling into the pans, and laterally extending resilient agitator means or flexible aprons mounted thereon for knocking insects from the side branches of the plants.
