Abstract
The present invention is a barrel screen apparatus comprising an elongate, hollow, cylindrical and rotatable barrel screen cage having a receiving end and a discharge end. A hopper is positioned adjacent to the receiving end of the barrel screen cage and has a pair of augers to convey the material and regulate the rate of feed into the feed end of the barrel screen cage. A concave plate is attached to the support frame and positioned directly below and along the length of the barrel screen cage to catch the screened material through the cage. Spiral flighting is attached to the external periphery of the barrel screen cage to convey the material forwardly on the concave plate towards the front of the apparatus where stripper bars, mounted longitudinally on the periphery, push the material off the side of the apparatus. The material accumulates adjacent to a fold-down apron on the side of the apparatus which facilitates pickup by a front-end loader or other means.
