This invention provides an improved, safety overload prevention device for a material conveying auger which includes an auger casing, a main drive shaft journalled therein and a main auger flight secured around the shaft, an intake flight section (11) secured to and extending along a tubular support sleeve (12) rotatably mounted on an intake drive shaft portion (14) which is adapted for connection to the main drive shaft of the auger so as to rotate therewith, and a clutch device (18) operatively interconnecting the tubular sleeve (12) and the drive shaft portion (14), the clutch device (18) including a radially displaceable spring loaded detent (19) movable between an engaged position wherein the tubular sleeve (12) is fast with the drive shaft portion (14) and rotates therewith, and a disengaged position wherein drive to the tubular sleeve (12) is disengaged in the event of an obstruction, such as a leg or arm being trapped in the flighting.
L'invention porte sur un dispositif de sûreté prévenant les surcharges dans les transporteurs à vis de matériaux et comprenant: un carter; un arbre moteur y étant monté sur paliers; et une vis hélicoïdale principale solidaire de l'axe. Le dispositif comporte en outre une section d'introduction (amont) de la vis, solidaire d'un tube support (12) monté tournant sur la partie d'introduction (amont) de l'arbre moteur (14), et pouvant ou non lui être crabotée pour tourner avec lui; et un embrayage (18) assurant la liaison entre le tube (12) et la portion (14) de l'arbre d'entraînement (14). Ledit embrayage (18) comporte une clavette (19) à ressort, mobile entre une position crabotée où le tube (12) est solidaire de l'arbre moteur (14) et tourne avec lui, et une position non crabotée où le tube (12) se désolidarise de l'arbre moteur (14) au cas ou un élément obstruant, tel qu'un bras ou une jambe, vienne se prendre dans la section amont de la vis
