Telle que représentée en figure 1, la potence porte-outil selon l'invention comprend un premier ensemble vertical 1 destiné à être fixé au véhicule. II est constitué d'un fourreau de section carrée doté de pattes de fixation et d'une bande longitudinale 3 sur chacun de ses côtés, dotée d'une rangée de perçages 4 permettant un réglage en hauteur sur un support adapté, non représenté, fixé au véhicule tracteur. As shown in Figure 1, the tool holder according to the invention comprises a first vertical assembly 1 intended to be fixed to the vehicle. It consists of a sheath of square section provided with fixing lugs and a longitudinal band 3 on each of its sides, provided with a row of holes 4 allowing adjustment in height on a suitable support, not shown, fixed to the towing vehicle.

Dans le fourreau 1 est monté un coulisseau 5 (figure 3) mobile de bas en haut et inversement sous l'action d'un piston hydraulique V interne au fourreau 1. L'extrémité du coulisseau 5 est doté de deux pattes 6 parallèles sensiblement orthogonales au tube 8, du deuxième ensemble réceptionnant le deuxième ensemble vertical 7 articulé sur le coulisseau 5 et sur les pattes 6 comme il sera expliqué dans la présente description. In the sheath 1 is mounted a slider 5 (FIG. 3) movable upwards and vice versa under the action of a hydraulic piston V internal to the sheath 1. The end of the slider 5 is provided with two substantially orthogonal parallel tabs 6 to the tube 8, the second assembly receiving the second vertical assembly 7 articulated on the slider 5 and the tabs 6 as will be explained in this description.

Le deuxième ensemble 7 comprend un tube 8 de préférence de section carrée articulé en 9 à sa base sur les pattes parallèles 6 à une de leurs extrémités dites internes et une bielle verticale 10 parallèle au tube 8 articulée à l'extrémité externe des dites pattes 6 formant un parallélogramme déformable. The second set 7 comprises a tube 8 preferably of square section articulated at 9 at its base on the parallel tabs 6 at one of their so-called internal ends and a vertical connecting rod 10 parallel to the tube 8 articulated at the outer end of said tabs 6 forming a deformable parallelogram.

L'extrémité supérieure du tube 8 est conformée en une chape qui reçoit via une articulation 11 le troisième ensemble 12 déporté sensiblement perpendiculairement au deuxième ensemble vertical 7. Ledit troisième ensemble 12 est constitué de deux lames parallèles 13 entretoisées formant une poutre de préférence en forme de «S» dont l'extrémité distale par rapport à l'extrémité en chape du tube 8 ou ladite poutre est articulée en 11 (figure 1) et est à un niveau supérieur de l'extrémité proximale dudit tube 8, l'extrémité de la poutre 12 est articulée en 14 sur la bielle 10. The upper end of the tube 8 is shaped as a yoke which receives via a hinge 11 the third assembly 12 offset substantially perpendicular to the second vertical assembly 7. Said third assembly 12 consists of two parallel blades 13 braced forming a beam preferably shaped of "S" whose distal end with respect to the tab end of the tube 8 or said beam is articulated at 11 (FIG. 1) and is at a higher level of the proximal end of said tube 8, the end of the beam 12 is articulated at 14 on the rod 10.

La figure 4 montre en la constitution de l'ensemble 12 en vue éclatée et avec tous ses détails dont certains ne seront pas écrits pour simplifier la description. L'extrémité supérieure de la bielle 10 au-dessus du point d'articulation 14 avec l'ensemble 12 est dotée d'une chape 15 constituée de deux parois parallèles de forme sensiblement triangulaire dotée du côté de la poutre d'un perçage inférieur 16 avec axe d'articulation 17 et d'un perçage supérieur 18 avec axe d'articulation 19. Figure 4 shows the constitution of the assembly 12 exploded view and with all its details some of which will not be written to simplify the description. The upper end of the connecting rod 10 above the articulation point 14 with the assembly 12 is provided with a clevis 15 consisting of two parallel walls of substantially triangular shape with the beam side of a lower bore 16 with hinge pin 17 and an upper bore 18 with hinge pin 19.

Un vérin 20 hydraulique est articulé à la chape 15 sur l'axe 17 par son extrémité proximale 21 de la dite chape 15 et son extrémité distale 22 est articulée à la poutre 13 par l'axe 23 traversant ladite poutre. L'extrémité distale de la poutre 13 est dotée d'un organe de fixation d'un dispositif porte-outil lui-même non décrit. A hydraulic jack 20 is articulated to the yoke 15 on the axis 17 by its proximal end 21 of said yoke 15 and its distal end 22 is articulated to the beam 13 by the axis 23 passing through said beam. The distal end of the beam 13 is provided with a fastener of a tool holder device itself not described.

L'organe de fixation comprend une chape inférieure 24 sensiblement horizontale reliée à la poutre 13 par une articulation à chacune de ses extrémités. The fixing member comprises a substantially horizontal bottom yoke 24 connected to the beam 13 by a hinge at each of its ends.

L'articulation du côté du tube 8 s'effectue par l'intermédiaire d'une biellette en U 20 25 verticale dont deux perçages inférieurs 26 sont en relation avec deux perçages 27 de la chape 24 horizontale et reçoivent un axe 28 The articulation of the side of the tube 8 is effected by means of a U-shaped vertical rod 20 of which two lower bores 26 are in relation to two bores 27 of the horizontal yoke 24 and receive an axis 28

Deux perçages 29 supérieurs avec tube de guidage 30 à l'autre extrémité de la biellette en U 25 reçoivent un axe 31 traversant des perçages 32 des lames de 25 la poutre. Two upper holes 29 with guide tube 30 at the other end of the U-shaped rod 25 receive an axis 31 passing through bores 32 of the beams of the beam.

L'articulation de la chape 24 à son extrémité orientée vers l'extérieur, c'est à dire à l'opposé du tube 8 s'effectue par un dispositif amortisseur comprenant une tige centrale verticale 33 avec un bloc médian 34 doté d'un perçage traversant fileté 30 dans lequel se logent de chaque côté des vis à tête hexagonales 35 qui traversent respectivement chacune un perçage 36 de chacune des parois verticales de la chape 24. The articulation of the yoke 24 at its end facing outwards, that is to say opposite the tube 8 is effected by a damping device comprising a vertical central rod 33 with a median block 34 having a threaded through hole 30 in which are lodged on each side hexagonal head screws 35 which respectively pass respectively through a bore 36 of each of the vertical walls of the yoke 24.

De part et d'autre du bloc médian sur la tige 33 est enfilé un ressort 37 bloqué en position par rondelle et écrou. Ces ressorts 37 font fonction d'amortisseurs latéraux réglables pour pouvoir modifier la sensibilité de l'amortissement. L'extrémité supérieure de la tige 33 est constituée d'un tube entretoise 38 qui s'insère entre les lames 13 de la poutre et y est bloqué par un axe boulonné 39 passant par des perçages 40 de chaque paroi 13 de la poutre. Le tube entretoise est librement rotatif sur l'axe 39. 10 Une barre qui peut être à vis réglable 41 est montée sur l'axe 19 correspondant aux perçages 18 des ailes 15 de la chape supérieure de la bielle 10. La barre à vis 4 est montée à son autre extrémité sur l'axe 28 qui raccorde la biellette verticale 25 et la chape horizontale 24. En figure 2 est représenté le positionnement de la potence porte-outil pour l'adapter à la position du rang de culture par rapport au véhicule recevant ladite potence. On either side of the median block on the rod 33 is threaded a spring 37 locked in position by washer and nut. These springs 37 act as adjustable lateral dampers in order to modify the sensitivity of the damping. The upper end of the rod 33 consists of a spacer tube 38 which is inserted between the blades 13 of the beam and is blocked by a bolted pin 39 passing through holes 40 of each wall 13 of the beam. The spacer tube is freely rotatable on the axis 39. A bar which can be adjustable screw 41 is mounted on the axis 19 corresponding to the holes 18 of the wings 15 of the upper yoke of the rod 10. The screw bar 4 is mounted at its other end on the axis 28 which connects the vertical link 25 and the horizontal yoke 24. In Figure 2 is shown the positioning of the tool holder to adapt to the position of the crop row relative to the vehicle receiving said stem.

20 Il sera noté que sous l'ensemble 12 est représenté de manière schématique un dispositif 42 recevant le support d'outil non représenté. It will be noted that under the assembly 12 is shown schematically a device 42 receiving the tool support not shown.

Par compression du piston 20, une traction exercée sur la chape 15 de la bielle 10 incline celle-ci vers le bas dans la position représentée en traits discontinus 25 en déformant le parallélogramme constitué par le tube 8 et la bielle 10 et en fait avancer l'élément 12 et le porte-outil 41 d'une longueur de déplacement variable en fonction des souhaits de l'utilisateur mais toujours horizontalement. Ce déplacement peut être de quelques millimètres à plusieurs centaines de millimètres sans que soit modifiée la position en hauteur du porte-outil 41. 30 Cet effet est obtenu par le parallélogramme articulé oscillant réalisé en bout de l'élément 12 par la biellette 25, la chape 24 et l'amortisseur articulé qui 15 compensent par une oscillation en sens contraire l'effet d'abaissement vers le bas suivant un arc de cercle de l'extrémité distale de l'élément 12. En figure 5 est représentée la fixation sur la pièce 24 d'un portique porte-outils 25 qui s'effectue par chape 26 et axes articulés 27-28 ; un vérin 29 articulé étant disposé entre une chape 30 et l'axe 28, ce qui assure une sécurité et une limitation au mouvement d'oscillation du portique 25. By compressing the piston 20, a traction exerted on the yoke 15 of the rod 10 inclines it downwards in the position shown in broken lines 25 by deforming the parallelogram formed by the tube 8 and the connecting rod 10 and advancing the element 12 and the tool holder 41 with a variable length of displacement according to the wishes of the user but always horizontally. This displacement can be from a few millimeters to several hundred millimeters without changing the height position of the tool holder 41. This effect is obtained by the oscillating articulated parallelogram made at the end of the element 12 by the link 25, the clevis 24 and the articulated damper 15 compensating for an oscillation in the opposite direction the effect of lowering downwardly along an arc of the distal end of the element 12. In FIG. 5 is shown the fixation on the part 24 of a tool carrier portico 25 which is made by clevis 26 and articulated axes 27-28; an articulated jack 29 being disposed between a yoke 30 and the axis 28, which ensures a safety and a limitation to the oscillation movement of the gantry 25.

Il va de soi que l'ensemble des vérins hydrauliques sont raccordés par des conduits non décrits à une source quelconque de puissance hydraulique et que 10 l'utilisateur dispose d'un tableau de commandes adapté. It goes without saying that all the hydraulic cylinders are connected by undescribed conduits to any source of hydraulic power and that the user has a suitable control panel.
