Abstract

La présente invention a trait à un appareil de protection contre la diffusion de fragments destiné au frein d'une pelleteuse. L'appareil de protection contre la diffusion de fragments inclut : un burin qui fait saillie vers le bas à partir du centre d'un corps principal de frein de manière à concasser un soubassement ; une plaque tampon de caoutchouc qui est dotée d'un trou d'insertion dans lequel le burin est inséré dans une partie centrale du corps principal doté d'une forme de plaque circulaire, la plaque tampon de caoutchouc permettant d'amortir les impacts appliqués au burin lorsque le soubassement est concassé ; une clavette inclinée qui est montée sur une surface extérieure du burin, la clavette inclinée étant dotée d'un diamètre extérieur augmentant graduellement vers son côté inférieur afin d'empêcher que la plaque tampon de caoutchouc ne se déplace vers le bas ; une plaque de fer de protection qui est disposée sur chacune des extrémités supérieure et inférieure de la plaque tampon de caoutchouc afin d'empêcher que la plaque tampon de caoutchouc ne soit endommagée ou afin d'empêcher que la clavette inclinée de soit séparée ; et une pluralité de boucles de fil métallique qui sont fixées sur une extrémité supérieure d'un côté de la plaque tampon de caoutchouc de manière à entourer une partie latérale du burin. De la sorte, selon la présente invention, la pelleteuse peut être dotée d'une durabilité maximisée et permet également d'empêcher que les éléments de la pelleteuse ne soient endommagés et usés par des fragments de soubassement.
