Title
(EN) SILO EMPTYING DEVICE WITH ADJUSTABLE HEIGHT DRAIN SCREW
(FR) DISPOSITIF DE VIDANGE DE SILO À VIS DE VIDANGE DE HAUTEUR AJUSTABLE
Abstract
(EN)
The invention relates to a device (1) for emptying a silo (20), having a central discharge orifice (21), said device (1) comprising a drain screw (2) which is rotatably supported by a beam (3) equipped with wheels (4) to form an assembly (5) for scanning the silo (20), a first system for rotatably driving the wheels (4) and a second system (7) for rotatably driving the drain screw (2), a base (8) that can be positioned in the central discharge orifice (21) of the silo (22), and comprising a fixed part surmounted by a movable part for coupling the so-called proximal end (51) of the scanning assembly (5) to said base (8), said movable part of the base (8) being a rotary part mounted rotatably on the fixed part of the base (8) about a vertical pivot axis (XX') transverse to the axis (YY') of rotation of the drain screw (2). The scanning assembly is mounted on the movable part of the base which is adjustable in angular position about an axis (ZZ'), orthogonal to the pivot axis (XX') of the movable part of the base (8).
(FR)
Dispositif (1) de vidange d'un silo (20) à orifice (21) d'évacuation central, ledit dispositif (1) comprenant une vis (2) de vidange supportée à rotation par une poutre (3) équipée de roues (4) pour former un ensemble (5) de balayage roulant permettant de balayer le silo (20), un premier système d'entraînement en rotation des roues (4) et un deuxième système (7) d'entraînement en rotation de la vis (2) de vidange, une embase (8) positionnable dans l'orifice (21) d'évacuation central du silo (22), et comprenant une partie fixe surmontée d'une partie mobile de couplage de l'extrémité (51) dite proximale de l'ensemble (5) de balayage à ladite embase (8), cette partie mobile de l'embase (8) étant une partie rotative montée à rotation sur la partie fixe de l'embase (8) autour d'un axe (XX') pivot vertical transversal à l'axe (YY') de rotation de la vis (2) de vidange. L'ensemble de balayage est monté sur la partie mobile de l'embase réglable en position angulaire autour d'un axe (ZZ'), orthogonal à l'axe (XX') pivot de la partie mobile de l'embase (8).
