Abstract
An apparatus for removing bulk materials from a laterally enclosed storage area wherein the apparatus may be substantially buried within the bulk material. The apparatus includes a support column mounted at a base into a support floor. An auger is attached by means of an axial mount at the base of the support column for enabling rotational inclination of the auger from (i) a vertical orientation wherein the auger is nearly parallel with the vertical axis of the support column, (ii) through intermediate angles of inclination, to (iii) a substantially horizontal orientation wherein the auger is adjacent to the support floor. The suspension cable is coupled between the support column and auger to enable selective adjustment of auger inclination. A rotational displacement drive is coupled to the support column to rotate the column about its vertical axis, along with the attached auger. A rotational drive motor is mounted at a distal end of the auger. Rotation of the auger, along with revolution of the support column provide for progressive removal of conical layers of surface material with each 360 degree revolution. Continued inclination to the horizontal level enables the total volum…
