Abstract
Abstract A bowl type earth moving vehicle auger apparatus employing vertical augers above the earth inlet opening and scraper, the augers having free lower ends and having the upper ends specially mounted in a floating fashion to accommodate entry of large objects such as rocks. The auger lower end is laterally controllably shiftable in response to lateral stresses as a result of a special bearing assembly on the auger upper end shaft, and the auger is vertically shiftable in response to vertical stress as a result of the mounting arrangement of the auger framework to the bowl assembly. Also, the auger is vertically shiftable in cooperation with opening of the apron, as a result of the auger framework being specially cooperable with the apron elevating mechanism, to assure free discharge flow from the bowl without auger interference.
