A compartmented bucket wheel assembly in which the compartments extend radially inward and angularly opposite the direction of wheel rotation to facilitate emptying of the compartments and thereby increase the capacity of the bucket wheel. In a structurally simple but sturdy preferred form, the buckets are mounted between the extremities of a plurality of plate members, the outer portions of which extend diagonally outward in the direction of wheel rotation at an obtuse angle to the radially directed inner portions thereof. A number of flat, generally triangular plates disposed between the outer portions of adjacent plate members deflect the material toward the discharge edge which extends diagonally inward from the periphery of the wheel adjacent the front of the bucket along one lateral edge of the outer portion of the leading plate member associated with a particular bucket, to the intersection of the inner and outer portions of the associated trailing plate member.
