Abstract
A novel feeding system and feeder unit for supplying feed to hogs and like animals is disclosed. The feeding system includes a plurality of the novel feeders, and a feed conveyor adapted to deliver feed to each feeder. Each feeder comprises an immobile pan, and superstructure affixed over and to the pan. A threaded shaft is journaled so as to extend upwardly from the pan. A rotor gate is journaled over the pan and is threaded on the shaft means. Under normal conditions, the rotor gate simply turns within the pan and agitates the feed being consumed by the hogs. However, when a latch is depressed, the threaded shaft is immobilized, and rotation of the rotor gate about the immobilized shaft acts to raise and lower the rotor gate relative to the pan. This relative motion adjusts the size of at least one feed-delivery gate space defined between the rotor gate and the pan.
