Patent

CA 2334242

The invention relates to a material conveying assembly (10) of the kind comprising an outer tubular casing (11) and a rotary feed screw (12) mounted within the casing (11) on a tubular drive shaft (13), wherein the intake end of the auger is provided with a replacement intake auger sub-assembly (14) comprising flexible helical flighting (15) freely rotatably mounted on a drive shaft extension (17) which is connected to the main drive shaft (13) and a clutch device (30) which drivingly connects the intake flighting shaft portion (25) to the drive shaft extension (17). The clutch device is arranged so that it will automatically disengage drive to the shaft portion (25) in the event of an overload occurring. A soft pliable extension sleeve (19) is co-axially fitted over the open leading end of the outer casing (11) and is arranged to encircle a portion of the intake flighting (15). The extension sleeve (19) being easily deformable, in combination with the resilient flexible flighting (15) significantly reduces the likelihood of any injury being suffered by an operator in the event of one of his or her limbs being caught in the intake flighting.

La présente invention concerne un assemblage convoyeur (10) de matériau du type qui comprend un fourreau tubulaire (11) extérieur et une vis d'alimentation rotative (12) contenue dans le fourreau (11) et montée sur une arbre de commande tubulaire (13). Dans cet assemblage, l'extrémité d'alimentation de la vis est remplacée par un sous-assemblage de vis sans fin (14) constitué de spires flexibles (15) montées rotativement libres sur une extension d'un arbre de commande (17) reliée à l'arbre de commande (13) principal, d'un mécanisme d'embrayage (30) qui couple mécaniquement la partie d'arbre (25) supportant les spires d'alimentation à l'extension d'arbre (17). Le dispositif d'embrayage est conçu de manière à permettre un désaccouplement automatique de la partie d'arbre (25) en cas de surcharge. Un manchon d'extension (19) flexible et pliable est fixé coaxialement sur les ouvertures d'extrémité du fourreau (11) extérieur et disposé de manière à entourer une partie des spires d'alimentation (15). Ce manchon d'extension (19), facilement déformable, permet, en combinaison avec les spires flexibles (15) et résiliantes, de réduire la probabilité de blessures occasionnées à un opérateur, ou à une opératrice, au cas où un de leurs membres serait accidentellement pris dans les spires d'alimentation.
