ABSTRACT:
A device to remotely extract particulate material comprises a number of archimedes screw sections joined end-to-end by universal joints and surrounded by a housing which articulates at the universal joints. The screw sections terminate in a material extraction head at the ingress end of the housing. A housing support runs the length of the housing and includes push arms which extend to the housing proximate the ingress end of the housing. The push arms may be remotely extended in order to translate the material extraction head. Furthermore, the housing support may be rotated about its longitudinal axis to move the material extraction head. In this way material over an area may be extracted.
