Lors de son deplacement, I'engin 10 assure ['extraction de la roche sur une hauteur par exemple egale a un metre et correspondent sensiblement a la hauteur des roues inclinees 34. Le front de taille F est defini a l'extremite During its displacement, the machine 10 ensures the extraction of the rock over a height for example equal to one meter and corresponds substantially to the height of the inclined wheels 34. The size F front is defined at the end
d'un talus T forme en avant de l'engin, comme illustre sur les figures 1 et 3. a slope T forms in front of the machine, as illustrated in FIGS. 1 and 3.
Lors de ['exploitation, la bande du convoyeur 50 est maintenue en mouvement et les roues 34 qui vent entranees en rotation dans des sens opposes. Les roues tournent dans un sens tel qu'elles assurent un guidage des blocs vers l'intervalle de concassage 38. Ainsi, les roues tournent de telle sorte que les dents se deplacent du front avant 39 vers l'intervalle de During operation, the conveyor belt 50 is kept in motion and the wheels 34 which are rotated in opposite directions. The wheels rotate in a direction such that they guide the blocks towards the crushing interval 38. Thus, the wheels rotate so that the teeth move from the front edge 39 towards the interval of
concassage 38.crushing 38.
Le chassis 12 equipe des chenilles 20 assure un avancement lent de l'engin suivant une direction d'avancement generalement rectiligne notee A. Simultanement a l'avancement de l'engin, le corps 14 effectue un mouve ment angulaire alternatif autour de l'axe X-X, de sorte que la tete 16 baiaye The chassis 12 fitted with tracks 20 ensures slow advancement of the machine in a generally rectilinear direction of advance noted A. Simultaneously with the advancement of the machine, the body 14 performs an alternating angular movement around the axis XX, so that the head 16 baiaye
un arc de cercle ouvert sur environ 30 et centre autour de l'axe X-X. an arc of a circle open on approximately 30 and center around the axis X-X.
Le debattement angulaire de la tete 16 est reparti symetriquement par rapport a l'axe longitudinal de l'engin. II est tel que la tete balaie depuis ses The angular movement of the head 16 is distributed symmetrically with respect to the longitudinal axis of the machine. It is such that the head sweeps from its
deux extremites une distance superieure a l'ecartement des chenilles 20. two ends greater than the distance between the tracks 20.
Lors de l'avancement de l'engin et du balayage par la tete 16, on comprend que les roues contre-rotatives 34 vent pressees contre le front de taille F definissant l'extremite du talus T. de sorte que, sous ['action de leur rotation, les roues assurent le decrochage de blocs de roche. Ces blocs de roche vent entranes dans l'intervalle de concassage 38, entre les deux roues. En etant compresses entre les deux roues, les blocs de roche voient During the advancement of the machine and the sweeping by the head 16, it is understood that the counter-rotating wheels 34 are pressed against the face of size F defining the end of the slope T. so that, under the action of their rotation, the wheels ensure the unhooking of rock blocks. These rock blocks wind entranée in the crushing interval 38, between the two wheels. By being compressed between the two wheels, the blocks of rock see
leur taille reduite pour former des granulate constitues des blocs concasses. their reduced size to form granulate made up of crushed blocks.
A la sortie de l'i nterval le de concassage 38, les blocs concasses tom bent a I'extremite de recueil du convoyeur 50, lequel achemine ces blocs jusqu'au convoyeur 102. Ce dernier conduit les blocs concasses jusqu'au convoyeur 104, loquel amene les blocs concasses jusqu'a une zone de stockage ou de traitement. La presence des deux roues contre-rotatives 34 permet d'assurer a la fois un detachement des blocs de roche de la carriere et un concassage de ces blocs de roche. Dans la mesure ou les roues 34 ont leurs axes de rota tion Z,-Z, et Z2-Z2 inclines par rapport a la verticale X-X, I'extremite de re cueil du convoyeur peut etre disposee dans ['angle a generalement au dessous de ces roues, assurant ainsi une evacuation facile des blocs concasses. De plus, le mouvement oscillant de la tete de travail 16 par rapport au chassis 12 autour d'un axe perpendiculaire au plan d'appui de l'engin permet d'assurer l/exploitation de la carriere sur une grande largeur, cette largeur At the exit from the crushing center 38, the crushed blocks fall at the collecting end of the conveyor 50, which conveys these blocks to the conveyor 102. The latter leads the crushed blocks to the conveyor 104, loquel brings the crushed blocks to a storage or processing area. The presence of the two counter-rotating wheels 34 ensures both the detachment of the rock blocks from the quarry and the crushing of these rock blocks. Insofar as the wheels 34 have their axes of rotation Z, -Z, and Z2-Z2 inclined relative to the vertical XX, the receiving end of the conveyor can be arranged in the angle generally below these wheels, thus ensuring an easy evacuation of the crushed blocks. In addition, the oscillating movement of the working head 16 relative to the chassis 12 about an axis perpendicular to the support plane of the machine makes it possible to ensure the exploitation of the quarry over a large width, this width
etant inferieure a la largeur de la tete de travail. being less than the width of the working head.
L'engin d'extraction decrit ici et ['installation dans laquelle il est integre permettent de staffranchir des engine independents utilises jusqu'alors dans les carrieres, reduisant ainsi les frais de personnel occasionnes par la The extraction machine described here and the installation in which it is integrated make it possible to staff independent engines previously used in quarries, thus reducing the personnel costs occasioned by the
conduite de ces engine.driving these engine.
