Abstract
Abstract A carrot topping machine in which carrots are delivered to an orientating apparatus by an upwardly-inclined elevator. The elevator has a box-like casing over which runs carrot-conveying flights carried by bars connected between conveying chains. A supply hopper is located adjacent the bottom of the elevator, the hopper permitting passage of the bars and flights to pick up carrots. Adjacent the top of the casing is an opening over which the flights pass so that excess carrots fall into the casing from which they are re-directed back to the hopper by chutes. Feed paddle wheels are located at the top of the elevator to receive the carrots and roll them on to the orientating apparatus.
