Abstract

A feed distribution system for animals comprising a hopper for containing feed, a spinner plate mounted beneath the feed outlet of the hopper, and a motor for rotating the spinner plate. A closure apparatus for the spinner plate includes a central shaft and at least two support legs. The spinner plate is mounted on a motor shaft extending from the motor and is biased upward by the support legs to force the plate towards the bottom of the hopper. In the resting position, a minimal gap is maintained between the spinner plate and the bottom of the hopper such that the spinner plate can rotate without interference, but vermin cannot reach into the gap to access feed that may be on the spinner plate. The support legs are biased by a first biasing member to be in extension to inhibit the edge of the plate from being pulled downward if vermin try to hang from or pull down on the plate. Rotation of the spinner plate generates a centrifugal force to force the support legs into flexion and move the spinner plate downward along the central shaft away from the hopper and, thereby creating a larger gap and allowing the feed to be dispersed during the rotation of the spinner plate.
