Description
La présente invention a pour objet un perfectionnement aux godets à crible pour chargeur frontal. The present invention relates to an improvement to screen buckets for a front loader.
Il est connu d'employer des godets appelés godets "squelette" qui sont constitués par un godet de forme usuelle, mais dont le fond est constitué, en tout ou en partie par une grille,Ainsi, lorsque le chargeur frontal charge sur le tas, en fonction de l'espacement des barreaux de la grille. It is known to use buckets called "skeleton" buckets which are constituted by a bucket of usual shape, but the bottom of which is constituted, in whole or in part by a grid, Thus, when the front loader loads on the heap, according to the spacing of the bars of the grid.
les éléments les plus gros sont enlevés, tandis que les éléments fins restent sur place, ce qui nécessite de revenir ensuite avec un autre godet pour évacuer ces éléments fins.the larger elements are removed, while the fine elements remain in place, which requires returning with another bucket to remove these fine elements.
Il est également connu d'employer des godets appelés "quatre en un qui sont constitués en deux parties : un bouclier muni d'oreilles de fixation aux extrémités des deux bras du chargeur frontal et une partie mobile articulée sur ce bouclier, cette partie mobile comportant une lame horizontale portée par deux parois latérales ; l'ensemble comportant une paire de vérins, situés chacun à une extrémité latérale, permettant de déplacer la partie mobile par rapport au bouclier. It is also known to use buckets called "four in one" which are made up of two parts: a shield provided with fixing ears at the ends of the two arms of the front loader and a movable part articulated on this shield, this movable part comprising a horizontal blade carried by two side walls; the assembly comprising a pair of jacks, each situated at a lateral end, making it possible to move the mobile part relative to the shield.
Lorsque la partie mobile est serrée contre le bouclier, l'ensemble forme un godet normal i lorsqu'elle est complètement relevée, le bouclier devient une lame de terrassement ; lorsqu'elle est légèrement relevée, l'engin peut être utilisé comme un décapeur (scraper) ; lorsqu'elle est actionnée contre le bouclier, le godet peut être employe comme une benne preneuse. Cependant, ces dispositifs ne peuvent pas être. employés pour les opérations de criblage qui consistent à séparer dans un tas de matériau les particules fines (sables et gravillons par exemple) des grosses (pierres ou cailloux). When the movable part is pressed against the shield, the assembly forms a normal bucket i when it is completely raised, the shield becomes an earthmoving blade; when slightly raised, the machine can be used as a scraper; when pressed against the shield, the bucket can be used as a clamshell. However, these devices cannot be. employed for the screening operations which consist in separating in a pile of material the fine particles (sand and gravel for example) from the large ones (stones or pebbles).
La présente invention concerne un godet de criblage facilitant considérablement les opérations de criblage. The present invention relates to a screening bucket which considerably facilitates screening operations.
Le godet selon la présente invention est constitué en deux parties articulées l'une à l'autre, la partie mobile étant constituée par une poche comportant un fond, muni d'une lame, deux joues latérales et une paroi arrière constituée par une grille, la paroi du bouclier étant conformée à la forme de la grille de façon à pouvoir l'obturer quand les deux parties sont serrées l'une contre l'autre
A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés Figure 1,une une vue d'un exemple de réalisation d'une poche munie d'une grille ;
Figure 2, une vue de la pièce dorsale mobile destinée à êt-re articulée sur la poche de la figure 1 ;
Figure 3, une vue de ces deux éléments assemblés et portés par les bras d'un chargeur frontal ;;
Figure 4, une vue du déchargement des matières fines;
Figure 5, une vue du déchargement des matières retenues par la grille.The bucket according to the present invention consists of two parts hinged to each other, the movable part being constituted by a pocket comprising a bottom, provided with a blade, two lateral cheeks and a rear wall constituted by a grid, the wall of the shield being conformed to the shape of the grid so as to be able to close it when the two parts are pressed against each other
By way of non-limiting example and to facilitate understanding of the invention, there is shown in the accompanying drawings Figure 1, a view of an exemplary embodiment of a pocket provided with a grid;
Figure 2, a view of the movable back piece intended to be re-articulated on the pocket of Figure 1;
Figure 3, a view of these two elements assembled and carried by the arms of a front loader;
Figure 4, a view of the discharge of fine materials;
Figure 5, a view of the unloading of materials retained by the grid.
En se reportant aux figures 1 et 2, on voit que le godet est constitué de deux éléments : une poche 1 (figure 1) et un bouclier 2 (figure 2). La poche 1 comporte deux parois latérales ou "joues" 3, un fond 4 et un dos 5 qui est constituée par une grille. L'écartement des barreaux constituant la grille est déterminée à volonté en fonction des dimensions du criblage souhaité;
A son sommet et à chacune de ses extrémités, la poche 1 comporte une chape 6 munie à sa base de deux orifices 7 et 8 faisant paliers.Referring to Figures 1 and 2, we see that the bucket consists of two elements: a pocket 1 (Figure 1) and a shield 2 (Figure 2). The pocket 1 has two side walls or "cheeks" 3, a bottom 4 and a back 5 which is constituted by a grid. The spacing of the bars constituting the grid is determined at will according to the dimensions of the desired screening;
At its apex and at each of its ends, the pocket 1 comprises a yoke 6 provided at its base with two orifices 7 and 8 forming bearings.
Le bouclier 2 comporte une paroi pleine 9 dont la forme et les dimensions correspondent exactement à celles de la grille 5 de la poche 1. A cette paroi 9 sont soudées deux oreilles 10 identiques qui sont munies chacune de deux orifices 11, 12 faisant paliers. The shield 2 has a solid wall 9 whose shape and dimensions correspond exactly to those of the grid 5 of the pocket 1. To this wall 9 are welded two identical ears 10 which are each provided with two orifices 11, 12 forming bearings.
A chacune de ces extrémités, le bouclier 2 comporte un boîtier 23 à I'intéieur duquel est monté un vérin 14. At each of these ends, the shield 2 comprises a housing 23 inside which a jack 14 is mounted.
A sa base chaque vérin 14 est monté à pivotement sur un tourillon qui, dans l'exemple représenté, est exactement aligné sur l'axe des paliers 11 L'extrémité de la tige du vérin 14 est munie d'un maneton 14a. D'autre part, chaque boîtier 23 comporte une paire de paliers 13 destinés à recevoir un axe 15.At its base each cylinder 14 is pivotally mounted on a pin which, in the example shown, is exactly aligned on the axis of the bearings 11 The end of the rod of the cylinder 14 is provided with a crank pin 14a. On the other hand, each housing 23 comprises a pair of bearings 13 intended to receive an axis 15.
Comme on le voit sur la figure 3, la poche 1 est montée à rotation sur le bouclier 1 a-u moyen de deux axes 15 passant à travers les paliers 7 de chaque chape 6 de la poche et 13 du bouclier. L'extrérnité 14a du vérin 14 est monté sur un axe 16 passant à travers les paliers 8 de la poche : ainsi en actionnant les deux vérins 14, on fait pivoter la poche 1 autour des deux axes 15 qui sont alignés. As seen in Figure 3, the pocket 1 is rotatably mounted on the shield 1 by means of two axes 15 passing through the bearings 7 of each yoke 6 of the pocket and 13 of the shield. The end 14a of the jack 14 is mounted on an axis 16 passing through the bearings 8 of the pocket: thus by actuating the two jacks 14, the pocket 1 is pivoted around the two axes 15 which are aligned.
Le bouclier 2 est porté par les deux bras du chargeur à savoir la flèche 17 e-t le bras de cavage 18 au moyen des axes 19 et 20, passant à travers les paliers li et 12. The shield 2 is carried by the two arms of the loader, namely the arrow 17 and the digging arm 18 by means of the axes 19 and 20, passing through the bearings li and 12.
La figure 3 represente la phase de chargement au tas, ce tas-comprenant des éléments de grosse taille, comme des pierres 21 mélangées à du sable 22. Le godet porté par les deux bras 17 et 18 est enfoncé dans le tas et est rempli du mélange de pierres et de sable. FIG. 3 represents the loading phase in the heap, this heap comprising large elements, such as stones 21 mixed with sand 22. The bucket carried by the two arms 17 and 18 is pushed into the heap and is filled with the mixture of stones and sand.
La figure 4 représente le criblage de la matière chargée dans le godet. On voit que, en actionnant les vérins 14, on fait pivoter la poche 1 vers le haut (flèche
F) par rapport au bouclier 2 qui reste fixe, ce pivotement s'effectuant autour des axes 15. Ce mouvement sépare la grille 5 de la paroi pleine 9 du bouclier et les mat-ières fines 22, sable et gravillons par exemple, s'écoulent à travers la grille 5, les gros éléments 21 étant retenus dans la poche.Figure 4 shows the screening of the material loaded in the bucket. It can be seen that, by actuating the jacks 14, the pocket 1 is pivoted upwards (arrow
F) relative to the shield 2 which remains fixed, this pivoting being effected around the axes 15. This movement separates the grid 5 from the solid wall 9 of the shield and the fine materials 22, sand and gravel for example, s' flow through the grid 5, the large elements 21 being retained in the pocket.
La figure 5 représente le déchargement des gros elements 21. Pour cette aération, la poche 1 est ramenée contre le bouclier 2 par les vérins 14 et tout le godet est basculé autour de l'axe 19 par le bras de cavage 18. FIG. 5 represents the unloading of large elements 21. For this ventilation, the pocket 1 is brought back against the shield 2 by the jacks 14 and the whole bucket is tilted around the axis 19 by the digging arm 18.
Grâce à un tel godet, on réalise à chaque cycle de chargement/déchargement le criblage des matières du tas. Thanks to such a bucket, the heap materials are screened at each loading / unloading cycle.
