  • Patent number: 4317494
    Abstract: A material removal device for removing auger spoil from a drilling site (such as, for example, an earth situs). A hollow spoil-receiving container is provided having an inclined floor and having a generally vertically disposed barrel portion secured to the inclined floor adjacent the upper end thereof for enclosing a preselected axial length portion of the auger with a snug operable fit. The auger is operably movable in the container barrel portion during drilling to permit the spoil from the drilling operation to be carried upwardly through the barrel portion by the auger flights and deposited in the main part of the container. The container also has a selectively lockable door vertically hinged on the container at a point adjacent the lower end of the container inclined floor. A generally vertically disposed elongated framework structure is secured to the container and extends upwardly therefrom.
