de la pelle de la figure 2.from the shovel of Figure 2.
La pelle hydraulique schématisée sur la figure 1 est une pelle classique comprenant une flèche 1 portant à son extrémité un balancier 2 commandé par un vérin hydraulique 3. Le balancier 2 porte lui-même à son extrémité un godet 4 de type standard articulé autour d'un premier axe 5 à l'extrémité dudit The hydraulic excavator schematically in Figure 1 is a conventional excavator comprising an arrow 1 carrying at its end a rocker 2 controlled by a hydraulic cylinder 3. The rocker 2 itself carries at its end a bucket 4 of standard type articulated around a first axis 5 at the end of said
balancier 2.pendulum 2.
Le godet 4 est mû par un palonnier 6 articulé, d'une part, sur le godet et, d'autre part, sur le balancier 2 en un second axe 7. Le palonnier 6 est articulé en 8 (figure 3) sur l'extrémité de la tige d'un vérin hdyraulique 9 de commande du The bucket 4 is moved by a spreader 6 hinged, on the one hand, on the bucket and, on the other hand, on the balance 2 in a second axis 7. The spreader 6 is hinged at 8 (Figure 3) on the end of the rod of a hydraulic cylinder 9 of the
godet, porté par le balancier 2.bucket, carried by the pendulum 2.
Le godet cisailleur selon l'invention (figures 2 et 4) est constitué d'une paire de mâchoires définie par un bras fixe 10 solidarisable du balancier 2 et par un bras mobile 11 articulé sur le bras fixe 10 autour d'un axe symbolisé en 12 et The shearing bucket according to the invention (FIGS. 2 and 4) consists of a pair of jaws defined by a fixed arm 10 that can be secured to the rocker 2 and by a movable arm 11 hinged to the fixed arm 10 around an axis symbolized in FIG. 12 and
susceptible d'être commandé par la tige du vérin 9. capable of being controlled by the cylinder rod 9.
Le bras fixe 10 est monté sur le balancier 2 par les mêmes moyens que le godet standard 4. A cet effet, les axes 5 et 7 du godet sont engagés dans des perçages ménagés aux endroits The fixed arm 10 is mounted on the rocker 2 by the same means as the standard bucket 4. For this purpose, the axes 5 and 7 of the bucket are engaged in holes in the places
appropriés dans la partie postérieure du bras fixe 10. appropriate in the posterior part of the fixed arm 10.
La partie antérieure du bras fixe est conformée en mâchoire de cisaille et est munie d'une lame de coupe The front part of the fixed arm is shaped like a shear jaw and is provided with a cutting blade
inférieure 13 de préférence amovible et à dents de retenue 14. lower 13 preferably removable and retaining teeth 14.
Le bras mobile 11 comporte en partie postérieure un prolongement 15 susceptible d'être articulé sur la tige du The movable arm 11 comprises at the rear part an extension 15 that can be articulated on the rod of the
vérin 9 par le même axe 8 que le godet standard 4. cylinder 9 by the same axis 8 as the standard bucket 4.
La partie antérieure du bras mobile 11 est conformée en mâchoire antagoniste de celle du bras 10 et équipée également d'une lame de coupe supérieure 16 de préférence amovible et à The front part of the movable arm 11 is shaped like a jaw opposite to that of the arm 10 and is also equipped with an upper cutting blade 16 which is preferably removable and
dents de retenue 17.retaining teeth 17.
Le godet cisailleur est représenté sur la figure 4 en position d'ouverture maximale et sur la figure 2 (bras mobile 11') en position de fermeture totale sous la commande du The shearing bucket is shown in FIG. 4 in the maximum open position and in FIG. 2 (movable arm 11 ') in the fully closed position under the control of
vérin 9.cylinder 9.

Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes notamment en ce qui concerne les formes et dimensions des bras fixe 10 et mobile 11. Les bras 10 et 11 pourraient être non plus de part et d'autre de l'axe d'articulation 12, comme illustré sur les dessins, mais croisés à la manière d'une paire de ciseaux, le godet cisailleur étant dans ce cas fermé par rétraction maximale de la tige du Finally, the invention is obviously not limited to the embodiment shown and described above but covers all variants, particularly with regard to the shapes and dimensions of the fixed arm 10 and mobile 11. The arms 10 and 11 could be either on either side of the hinge axis 12, as shown in the drawings, but crossed in the manner of a pair of scissors, the shearing bucket being in this case closed by maximum retraction of the stem of
vérin 9.cylinder 9.
Par ailleurs, au lieu d'une cisaille à mâchoires simples comme représentée sur les dessins, l'une des deux mâchoires, supérieure ou inférieure, pourrait être double, l'autre mâchoire, simple, étant susceptible de pénétrer dans l'intervalle ménagé entre les deux parties parallèles de la Moreover, instead of a simple jaw shear as shown in the drawings, one of the two jaws, upper or lower, could be double, the other jaw, simple, being likely to enter the gap between the two parallel parts of the
mâchoire double.double jaw.
