Abstract

A hog feeder comprises a generally overhead horizontal conveyor for transporting feed to a series of drop tubes which contain centerless augers for delivering feed downwardly through the tubes to feed pans therebelow. Attached to the auger at its lower end are elements for engagement by the hogs during feeding to drive the centerless auger and thereby positively deliver feed to the feed pans. The system further includes a limit switch in the down tube of a control feeder unit located above the pan and below the horizontal conveyor for ensuring that there is always feed in the various other feeder units attached to the overhead conveyor.
