Abstract: An improved filter bucket for a flight conveyor having two sides and a bottom with an integral rake edge. Numerous equally spaced apart arcuately curved wires are fixed to and supported by longitudinally extended cross bars in a grid fashion to form the generally concave bucket bottom interior surface. The wires extend beyond the cross bar at the leading edge of the bucket to form a rake edge for engaging and retaining material conveyed. Perforated sides with numerous holes formed therethrough of diameter equal to the bottom grid spacing wires provide for a uniform filtering action filtering action through the bottom and sides of the bucket.
