  • Patent number: 5354236
    Abstract: A cost effective and efficient method and apparatus for converting a "husk-off" corn picker into a "husk-on" corn picker to reduce kernel loss and damage. The husking bed of the "husk-off" corn picker is removed and replaced with a corn conveyor consisting of a series of driven flights which convey corn from one end of the picker to the other. The corn conveyor is set at an elevated angle so that the uptake end is lower than the deposit end of the conveyor. A suction fan is attached to the picker above the corn conveyor and sets of rubber air dams are placed around the conveyor to increase the effectiveness of the fan. An air inlet means is provided in the side of the picker so that the suction means can pull air under the corn conveyor and across the deposit end of the corn conveyor as the ears of corn fall from the conveyor. This directed air flow pulls the debris from the ears of corn as the ears fall and carry the debris into the suction means where it is blown out and away from the corn picker.
