ABSTRACT:
An excavating bucket wheel has a plurality of radially outwardly open bucket chambers disposed in a circular array. During rotation of the bucket wheel each chamber cyclically assumes a material receiving position and a material dumping position. Each bucket chamber is defined by a cutting plate supported at the wheel periphery and having a trailing edge as viewed in the direction of wheel rotation, two axially spaced, parallel side walls and a rear wall extending axially between the side walls. An outer edge of the rear wall is situated adjacent the cutting plate. Each bucket chamber is further defined by a bottom wall extending axially between the side walls and being supported for pivotal motion about an axis oriented parallel to the rotary axis of the bucket wheel and situated adjacent the outer wheel periphery. The bottom wall has a first pivotal position for receiving material and a second pivotal position for dumping material. There is further provided a first actuating device for pivoting the bottom wall. Each rear wall is, at an inner edge thereof, supported for pivotal motion about an axis oriented parallel with the rotary axis of the bucket wheel. A second actuating device urges each rear wall into contact with the outer terminal edge of a respective bottom wall.
