Abstract
The present invention is directed to a rotary feeder device for transporting bulk shearable material. The rotary feeder comprises a main housing with a cylindrical passage therethrough, and an inlet port and a discharge outlet each communicating with the cylindrical passage of the main housing. There is a rotor disposed within the cylindrical passage that includes a plurality of pockets spaced peripherally thereabout which rotate successively past the inlet port and discharge outlet which are each defined by a pair of radially-extending rotor blades. The inlet port feeds material directly into the rotating pockets. At the very end of inlet port that is located directly above the rotating pocket area there is located anti-shearing edges that come in close communication with the outer free edges of the rotor blade as the latter rotate. The outer free edges of the rotor blades are located at a sufficient angle from the axial axis of the rotor so that any shearable material disposed partly within the inlet port and partly within a rotor pocket will not be sheared by the co-action between said edges of the inlet port and the leading edges of the rotor blades as they move from under the inlet port. Furthermore, the edges of the inlet port have a cavity provided underneath their front portion into which the partly disposed material is pushed by the rotating blade. The cavity leads into a pocket for the partly disposed material located near or on the inner wall of said housing. The edge of the rotor blades will serve to push the shearable material disposed in the cavity into the pocket.
