Abstract
Description
La présente invention a pour objet un perfectionnement aux dents latérales de godets de pelles mécaniques et plus particulièrement aux godets de pelles mécaniques travaillant en retro-cavage. The present invention relates to an improvement to the lateral teeth of mechanical shovel buckets and more particularly to mechanical shovel buckets working in backhoeing.
Il est connu de placer aux deux extrémités latérales dtun godet devant travailler en retro-cavage d'une part une dent et d'autre part une lame facilitant la découpe du sol. Mais il arrive que des cailloux se bloquent entre ces deux éléments. It is known to place at the two lateral ends of a bucket which has to work in backhoeing on the one hand a tooth and on the other hand a blade facilitating the cutting of the soil. But sometimes stones get stuck between these two elements.
Selon un premier aspect de la présente invention ces deux éléments sont faits en une seule pièce. Mais la fixation de telle pièce dite pièce de coin sur un godet pose de graves problèmes car cette pièce subit des efforts perpendiculaires : dune d'une part des efforts sensiblement perpendiculaires à la partie faisant dent lors du travail en poussée et du travail en retro-cavage ainsi que des efforts transversaux par rapport à la partie faisant lame. Il en résulte que leur fixation au godet se détériore souvent et quels sont arrachés.According to a first aspect of the present invention these two elements are made in one piece. But the fixing of such a part called a corner part on a bucket poses serious problems because this part undergoes perpendicular forces: on the one hand, forces substantially perpendicular to the toothed part during work in pushing and working in retro- digging as well as transverse forces relative to the blade portion. It follows that their attachment to the bucket often deteriorates and which are torn off.
La présente invention a pour objet des perfectionnements à ce type de matériel améliorant leur tenue aux efforts. The present invention relates to improvements to this type of material improving their resistance to stresses.
La dent latérale selon la présente invention est une dent comportant à la fois une pointe et une lame latérale réalisées en une seule pièce. De plus, elle comporte : une paroi plane de fixation latérale ; deux parois planes faisant coin ltune sensiblement horizontale passant sous la lame du godet, l'autre oblique venant prendre appui contre la tranche avant de la paroi latérale du godet ; et une butée latérale coopérant avec ladite paroi plane de fixation de façon à enserrer la paroi oblique du godet. The lateral tooth according to the present invention is a tooth comprising both a point and a lateral blade produced in one piece. In addition, it comprises: a flat side fixing wall; two planar walls forming a substantially horizontal corner passing under the blade of the bucket, the other oblique coming to bear against the front edge of the side wall of the bucket; and a lateral stop cooperating with said flat fixing wall so as to enclose the oblique wall of the bucket.
À A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention, on a représenté aux dessins annesta:
Figure 1 une vue latérale, avec coupe partielle, illustrant une dent latérale selon la présente invention
Figure 2 une vue en coupe selon A-A de la figure 1
Figure 3 une vue en coupe selon B-B de la figure 1.By way of nonlimiting example and to facilitate understanding of the invention, the annesta drawings are shown:
Figure 1 a side view, partly in section, illustrating a lateral tooth according to the present invention
Figure 2 a sectional view along AA of Figure 1
Figure 3 a sectional view along BB of Figure 1.
En se reportant à ces figures, on voit que le godet qui n'est que partiellement représenté comporte à chaque coin la jonction de la lame 1 et de la paroi latérale 2 et que ce coin est muni dune pièce de coin, appelée aussi dent latérale qui comporte à la fois une dent 3 et une lame 4. Referring to these figures, we see that the bucket which is only partially shown has at each corner the junction of the blade 1 and the side wall 2 and that this corner is provided with a corner piece, also called lateral tooth which has both a tooth 3 and a blade 4.
Cette pièce de coin travaille à la fois selon les forces représentées par f1 et t (en retro-cavage et en poussée) et latéralement. This corner piece works both according to the forces represented by f1 and t (backhoeing and pushing) and laterally.
La lame 4 est prolongée par une paroi latérale 5 qui sert à sa fixation sur la paroi latérale 2 du godet au moyen de trois boulons placés dans les orifices 6. De plus, la pièce de coin comporte deux parois 7 et 8 faisant coin qui viennent respectivement prendre appui, la paroi 7 sous la lame 1 et la paroi 8 contre la trache avant 2a de la paroi latérale 2 du godet. De préférence, la paroi 8 est rigoureusement parallèle à la tranche 2a contre laquelle elle s'applique sur toute sa longueur, tandis que la-paroi 7 est légèrement oblique par rapport à la face inférieure de la lame 7 d'une part pour faciliter la mise en place et d'autre part pour obtenir un effet de coincement. De plus, la paroi 7 est de faibles dimensions. The blade 4 is extended by a side wall 5 which is used for its attachment to the side wall 2 of the bucket by means of three bolts placed in the orifices 6. In addition, the corner piece has two corner walls 7 and 8 which come respectively take support, the wall 7 under the blade 1 and the wall 8 against the front trache 2a of the side wall 2 of the bucket. Preferably, the wall 8 is strictly parallel to the edge 2a against which it is applied over its entire length, while the wall 7 is slightly oblique with respect to the underside of the blade 7 on the one hand to facilitate the placement and secondly to obtain a wedging effect. In addition, the wall 7 is of small dimensions.
La portion de la dent latérale constituée par la paroi de fixation 5, la lame 4, et la paroi d'appui 8 comporte en outre une butée latérale 9 qui, en coopérant avec la paroi de fixation 5 vient enserrer une portion de la paroi latérale 2 du godet (figure 2). De préférence, comme cela est représenté à la figure 2 le rebord de la paroi latérale 2 est biseautée et la butée 9 comporte une paroi interne 9a inclinée de façon analogue au plan incliné 2b du biseau de façon à obtenir, là également, un effet de coincement. The portion of the lateral tooth formed by the fixing wall 5, the blade 4, and the support wall 8 further comprises a lateral stop 9 which, by cooperating with the fixing wall 5 encloses a portion of the side wall 2 of the bucket (Figure 2). Preferably, as shown in FIG. 2, the edge of the side wall 2 is bevelled and the stop 9 has an internal wall 9a inclined in a manner analogous to the inclined plane 2b of the bevel so as to obtain, here too, an effect of jamming.
Ainsi, par coincement entre les parois 7 et 8 dune part et les parois 5a et 9a d'autre part, on obtient une fixation très solide de la dent latérale qui lui confère une très bonne tenue au travail. Thus, by wedging between the walls 7 and 8 on the one hand and the walls 5a and 9a on the other hand, a very solid attachment of the lateral tooth is obtained which gives it very good work performance.
