Abstract

La présente invention concerne un conduit présentant une guillotine comprenant : un corps supérieur attaché et fixé à un côté d'un objet cible pour la fixation ; un corps inférieur accouplé en rotation à un côté du corps supérieur, qui guide le sens de convoyage d'une chaîne passant à travers ; une guillotine mise en rotation de manière sélective au moyen d'une pluralité de maillons sur un côté du corps inférieur de façon à limiter le mouvement vers le bas de la chaîne ; et un capot protecteur sur un côté du corps inférieur, qui empêche les objets étrangers d'entrer dans le corps inférieur. La guillotine comprend : un cylindre dont la longueur peut être agrandie de manière sélective ; une pluralité de premiers maillons accouplés de manière rotative au niveau de leur extrémité à un côté du cylindre ; une pluralité de seconds maillons accouplés de manière rotative à l'autre extrémité de la pluralité de premiers maillons ; et une guillotine accouplée et reliée à une extrémité de la pluralité de seconds maillons et raccordée de manière sélective à la chaîne de façon à limiter le mouvement de la chaîne dans un sens.
