Multi-wheeled excavating and loading system

摘要

In an excavating and loading system, an excavating wheel assembly comprises three excavating wheels each having a plurality of digging buckets. Each digging bucket is moved to the material receiving position during movement of the digging bucket through an initial portion of its rotation and to the material discharging position during a subsequent portion of its rotation. Material discharged from the digging buckets of the excavating wheel assemblies is received by conveyors and is transported thereby upwardly and rearwardly to a discharge point at the rear of the vehicle. The two outside excavating wheels of the excavating wheel assembly may be equipped with conical cutting members, whereby the excavation formed by the excavating and loading system is provided with tapered side walls.
