Abstract

Dispositif de vidange d’un silo à orifice d’évacuation central, ledit dispositif comprenant une vis (2) de vidange supportée à rotation par une poutre (3) équipée de roues (4) pour former un ensemble de balayage roulant, un racleur (13) équipant l’ensemble de balayage, un premier système d’entraînement en rotation des roues (4) et un deuxième système d’entraînement en rotation de la vis (2) de vidange, une embase positionnable dans l’orifice d’évacuation central du silo, cette embase comprenant une partie fixe surmontée d’une partie mobile rotative de couplage de l’ensemble de balayage à ladite embase. Le racleur (13) est monté, sur l’ensemble de balayage, mobile à pivotement autour d’un axe (VV') parallèle à l’axe de rotation de la vis (2) de vidange pour un déplacement dudit racleur (13) entre une position active rapprochée du sol, et une position inactive écartée du sol, et le dispositif de vidange comprend au moins deux actionneurs d’entraînement en déplacement du racleur (13) entre les positions active et inactive. (Figure 9)Device for emptying a silo with a central discharge port, said device comprising an emptying screw (2) rotatably supported by a beam (3) equipped with wheels (4) to form a rolling sweep assembly, a scraper ( 13) fitted to the sweeping assembly, a first drive system in rotation of the wheels (4) and a second drive system in rotation of the drain screw (2), a base that can be positioned in the discharge orifice central silo, this base comprising a fixed part surmounted by a rotating movable part for coupling the scanning assembly to said base. The scraper (13) is mounted, on the sweeping assembly, movable to pivot about an axis (VV ') parallel to the axis of rotation of the drain screw (2) for a movement of said scraper (13) between an active position close to the ground, and an inactive position away from the ground, and the emptying device comprises at least two actuators for driving the movement of the scraper (13) between the active and inactive positions. (Figure 9)
