ABSTRACT:
An extraction device comprises an inclinable scraper shaft driven in rotation along a first vertical axis of rotation, thereby extracting bulk products stored over a storage area having at least one evacuation opening. The extraction device comprises a support piece whose foundation is mounted to rotate above the evacuation opening along the first axis of rotation, defining a supporting base for the scraper shaft. The base is inclined by an angle .beta. with respect to the horizontal. The first driving member is provided to rotate the support piece and the scraper shaft about the first axis. The foundation of the scraper shaft is inclined with respect to the axis of the scraper shaft by an angle .alpha. complementary of the angle .beta. and is mounted to rotate on the base along a second axis of rotation perpendicular to said base. The extraction device further comprises a second driving member to rotate the scraper shaft about the second axis of rotation for adjusting the inclination of this shaft with respect to the vertical by an angle between 0.degree. and 90.degree..
