Abstract
An excavating and loading system includes an excavating and wheel assembly at the front thereof and a plurality of conveyors for conveying the material from the excavating wheel assembly upward and rearwardly. The excavating wheel assembly includes a pair of excavating wheels with a total width wider than the overall width of the following portions of the system. A supporting and housing apparatus extends between the excavating wheels and rotatably supports the same from the front of the vehicle. A power plant is provided and a drive shaft extends down along the supporting and housing means between the two excavating wheels. Gearing is provided in the interior of the wheels and is connected to the drive shaft for powering the excavating wheels. Apparatus is provided for raising and lowering excavation height of the excavation wheel assembly to thereby vary the grade of the excavation. The excavating wheels are provided with means for positively moving the walls of a plurality of buckets between material receiving and material discharge positions.
