Abstract
A closed loop feed trough having a feed chain moveable lengthwise therein to distribute feed from a hopper associated with the trough provided with an impeller which rotates in response to movement of the chain to assist in returning uneaten feed to the hopper. The impeller is mounted in the hopper adjacent its inlet and is fabricated in two halves which are fastened to opposite sides of a drive sprocket which engages the feed chain. Each half of the impeller has a hub and a series of vanes extending outwardly and rearwardly at spaced intervals from the hub to provide a series of buckets between the vanes. A baffle overlies the impeller to shield the buckets from feed in the hopper as they rotate downwardly toward the inlet while affording unloading of feed from between the vanes as they rotate upwardly away from the feed chain.
