Description

TRACTEUR ENJAMBEUR  TRACTOR ENJAMBEUR
La présente invention concerne un véhicule automoteur du type tracteur enjambeur, permettant de travailler toutes les parcelles agricoles , principalement maraîchères. The present invention relates to a self-propelled vehicle straddle tractor type, to work all agricultural parcels, mainly market gardeners.
Pour les travaux agricoles, il est connu d'utiliser des tracteurs surélevés permettant de passer au dessus des plants divers, et particulièrement des vignes, des plantations fruitières, des artichauts, .. et portant sous leur châssis les outils nécessaires à la réalisation des différentes tâches :  For agricultural work, it is known to use elevated tractors to pass over various plants, especially vines, fruit plantations, artichokes, .. and carrying under their chassis the tools needed to achieve the different tasks:
Labourage, binage, arrosage, épandage d'engrais, etc....  Plowing, hoeing, watering, spreading fertilizer, etc.
Ces tracteurs de type connu disposent de la configuration suivante :  These tractors of known type have the following configuration:
-un châssis disposé dans le sens du mouvement, porté par 4 roues dont la voie de roulement est légèrement supérieure à la largeur du châssis porteur ;  a chassis arranged in the direction of movement, carried by four wheels whose running track is slightly greater than the width of the undercarriage;
-une cabine de conduite , solidaire du châssis et dont la visibilité est orientée dans le sens du déplacement du tracteur ;  a driving cabin, integral with the chassis and whose visibility is oriented in the direction of the tractor's movement;
-des outils solidaires du châssis et placés sous celui-ci, généralement vers l'arrière.  tools integral with the chassis and placed under it, generally towards the rear.
Ce type de tracteur comporte les inconvénients suivants :  This type of tractor has the following drawbacks:
-la proportion de terrain couvert par le passage des roues est importante par rapport à la surface totale cultivable ; le passage des roues compacte le sol : cette compaction a des conséquences négatives sur la vie biologique des sols agricoles et leur structure physique, facilitant l'érosion et la pollution.  -the proportion of land covered by the passage of the wheels is important compared to the total cultivable surface; the compact passage of the wheels on the ground: this compaction has negative consequences on the biological life of agricultural soils and their physical structure, facilitating erosion and pollution.
Une part importante du travail du tracteur consiste à décompacter et à ameublir les sols qu'il a lui même détériorés.  A large part of the tractor's job is to decompact and loosen the soil that he himself has deteriorated.
-ces tracteurs roulant toujours dans la même direction, ils doivent faire demi tour à l'extrémité du terrain à travailler : ces manœuvres contribuent à la détérioration des sols et à la limitation de la surface cultivable par rapport au domaine,  -These tractors always drive in the same direction, they have to turn around at the end of the ground to work: these maneuvers contribute to the deterioration of the grounds and the limitation of the cultivable surface compared to the field,
-les outils fixés sous le châssis sont peu visibles ainsi que le résultat instantané de leur action : toute personne ayant vu un tracteur fonctionner, aura noté que le conducteur est en permanence tourné vers l'arrière, ce qui n'est pas pour le moins ergonomique et ne facilite pas la qualité de son travail.  -the tools attached to the chassis are not very visible as well as the instantaneous result of their action: anyone who saw a tractor running, will have noted that the driver is permanently facing back, which is not the least ergonomic and does not facilitate the quality of his work.
Le tracteur enjambeur selon l'invention permet de pallier ces inconvénients des tracteurs de type connu, en limitant le temps de travail rapporté à la surface effectivement cultivée et en préservant celle-ci.  The straddle tractor according to the invention makes it possible to overcome these disadvantages of tractors of known type, by limiting the working time related to the actually cultivated surface and preserving it.
Le tracteur enjambeur selon l'invention comporte en combinaison :  Straddle tractor according to the invention comprises in combination:
-une poutre châssis unique de grande longueur. Cette poutre est perpendiculaire au sens de déplacement du tracteur en phase de travail. Sans modifier l'invention cette poutre peut être une poutre treillis, par exemple de section triangulaire, ou constituée de profilés du commerce. -a single frame beam of great length. This beam is perpendicular to the direction of travel of the tractor during the work phase. Without modifying the invention this beam may be a trellis beam, for example of triangular section, or made of commercial profiles.
-cette poutre repose à ses deux extrémités sur des bras sous lesquels sont fixées des roues chacune de ces roues est à double sens de rotation et pivotantes autour d'un axe vertical en étant entraînées par des moyens de type connu par exemple de type moto-réducteur hydraulique. Ce type de montage permet par exemple grâce à des senseurs de position connectés à un ordinateur ou à un automate programmable de positionner les roues dans les positions permettant de tourner à 90°, de marcher en crabe, de tourner en carroussel permettant ainsi de s'adapter à toutes les configurations de terrains à cultiver, this beam rests at both ends on arms under which are fixed wheels each of these wheels is in two directions of rotation and pivoting about a vertical axis being driven by means of known type for example of motorcycle type. hydraulic reducer. This type of assembly allows, for example, thanks to position sensors connected to a computer or a programmable controller to position the wheels in the positions allowing to turn at 90 °, to walk in crab, to turn in carousel thus allowing to adapt to all the configurations of grounds to be cultivated,
-selon une autre caractéristique de l'invention la hauteur de cette poutre est réglable en hauteur par rapport aux bras supports de roues et donc au terrain. Selon un mode de réalisation préférentiel, le guidage vertical du mouvement de la poutre sera obtenu par le coulissement de tubes de section cylindrique ou carrée reliés respectivement au support et à la poutre coulissant l'un dans l'autre, la partie coulissante étant entraînée par exemple par des vérins hydrauliques.  according to another characteristic of the invention, the height of this beam is adjustable in height relative to the wheel support arms and thus to the ground. According to a preferred embodiment, the vertical guidance of the movement of the beam will be obtained by sliding tubes of cylindrical or square section respectively connected to the support and the beam sliding one into the other, the sliding part being driven by example by hydraulic cylinders.
-cette poutre porte un ensemble composé à sa partie supérieure de la cabine de conduite et à sa partie inférieure des porte outils pouvant se déplacer sur toute la longueur de la poutre par l'intermédiaire d'un chariot coulissant ou roulant sur cette poutre,  -This beam carries a set composed at its upper part of the driver's cab and at its lower part of the tool holders can move over the entire length of the beam by means of a carriage sliding or rolling on the beam,
-cet ensemble cabine de conduite-porte outils est pivotant à 180 ou 360° par rapport au chariot, sa position entre ces valeurs extrêmes pouvant être indexée, par exemple au moyen d'une couronne à crémaillère.  -This set driving cabin-tool holder is pivotable 180 or 360 ° relative to the carriage, its position between these extreme values can be indexed, for example by means of a rack-and-pinion.
Les figures annexées, données à titre d'exemple non limitatif, permettront de mieux comprendre les caractéristiques de l'invention et de ses avantages.  The appended figures, given by way of non-limiting example, will make it possible to better understand the characteristics of the invention and its advantages.
La figure 1 est une vue de face du tracteur enjambeur selon l'invention.  Figure 1 is a front view of the straddle tractor according to the invention.
La figure 2 est une vue de côté du tracteur enjambeur selon l'invention en représenté sur la figure 1 .  Figure 2 is a side view of the straddle tractor according to the invention shown in Figure 1.
La figure 3 est une vue de dessus du tracteur enjambeur en position de déplacement latéral entre deux parcelles.  Figure 3 is a top view of the straddle tractor in lateral displacement position between two plots.
On a représenté sur la figure 1 la poutre châssis 1 du tracteur enjambeur. Sa longueur peut être variable, selon le type de culture concernée, sans modifier l'invention. Elle est supportée par des supports 2 à chaque extrémité, sous lesquels sont fixées des roues 3 en nombre suffisant pour supporter la charge ,tout ou partie de ces roues étant motrices et orientables à 360°.  FIG. 1 shows the chassis beam 1 of the straddle tractor. Its length may be variable, depending on the type of crop concerned, without modifying the invention. It is supported by supports 2 at each end, under which are fixed wheels 3 in sufficient number to support the load, all or part of these wheels being driving and rotatable 360 °.
Un chariot 4 est supporté par la poutre châssis 1 ; il comporte des moyens connus, par exemple des galets 5 lui permettant de se déplacer sur toute la longueur de cette poutre châssis 1.  A carriage 4 is supported by the chassis beam 1; it comprises known means, for example rollers 5 allowing it to move along the entire length of this chassis beam 1.
Ce chariot 4 porte l'ensemble formé par la cabine de conduite 6/ porte outils 7, par l'intermédiaire d'un dispositif 8 permettant la rotation de cet ensemble par rapport au chariot 4 autour d'un axe vertical.  This carriage 4 carries the assembly formed by the driver's cab 6 / tool holder 7, through a device 8 allowing the rotation of this assembly relative to the carriage 4 about a vertical axis.
Les outils 9 sont fixés au chariot porte outil 7 par des systèmes de type connus, par exemple des parallélogrammes 10 déformables par vérins ou moteurs hydrauliques , permettant d'atteindre les plantations 11.  The tools 9 are fixed to the tool carriage 7 by known type systems, for example parallelograms 10 deformable by cylinders or hydraulic motors, to reach the plantations 11.
On a représenté sur la figure 2 une vue de côté du tracteur enjambeur représenté sur la figure 1.  There is shown in Figure 2 a side view of the straddle tractor shown in Figure 1.
La poutre 1 est solidaire d'un support 2, sous lequel sont placées les roues 3.  The beam 1 is secured to a support 2, under which are placed the wheels 3.
Celles ci sont orientables à 360° autour d'axes 12. A la partie supérieure des supports 2 des guidages 13, qui peuvent être des cylindres ou des tubes de section carrée, sont placés dans des profilés 14 de section correspondante pour permettre le coulissement, ces profilés étant liés à des vérins 15 solidaires des supports 2 ; on peut ainsi régler la hauteur de la poutre 1. These can be rotated 360 ° around axes 12. At the upper part of the supports 2 of the guides 13, which may be cylinders or tubes of square section, are placed in profiles 14 of corresponding section to allow sliding, these sections being connected to jacks 15 secured to the supports 2; it is thus possible to adjust the height of the beam 1.
On a représenté sur la figure 3 une vue de dessus du tracteur enjambeur selon l'invention. La poutre châssis 1 repose sur les supports 2 .Les roues 3 sont représentées en position parallèle à celle de l'axe de la poutre 1 pour permettre un déplacement latéral. A l'évidence ces roues 3 peuvent être dans n'importe quelle position intermédiaire par rotation autour de leur axe 12.  FIG. 3 shows a view from above of the straddle tractor according to the invention. The chassis beam 1 rests on the supports 2. The wheels 3 are shown in a position parallel to that of the axis of the beam 1 to allow lateral displacement. Obviously these wheels 3 can be in any intermediate position by rotation about their axis 12.
On comprend ainsi tous les avantages du tracteur enjambeur selon l'invention :  All the advantages of the straddle tractor according to the invention are thus understood:
-la surface des chemins de roues est très limitée par rapport à la surface cultivée ; the surface of the wheel paths is very limited with respect to the cultivated surface;
-la cabine et les outils sont placés de façon à permettre une visibilité maximum du travail des outils, sans demander au conducteur de se tourner ; -the cab and tools are placed so as to allow maximum visibility of the work tools, without asking the driver to turn;
-la hauteur de la poutre est réglable pour s'adapter à tous les types de culture, même de grande hauteur comme le maïs par exemple ;  the height of the beam is adjustable to adapt to all types of cultivation, even of great height such as corn for example;
-le tracteur peut se déplacer dans toutes les directions sans faire de manoeuvres telles que des demi-tours ;  the tractor can move in all directions without maneuvers such as half-turns;
On a donc réalisé un tracteur totalement différent des tracteurs existants qui apporte des solutions innovantes par rapport aux matériels existants :  We therefore realized a tractor totally different from existing tractors that brings innovative solutions compared to existing equipment:
-grande largeur de voie par rapport à la trace des roues -large track width relative to the wheel track
-visibilité optimum en mettant la cabine au dessus du sol, et au dessus du sillon ou du travail agricole réalisé, les outils pouvant être devant le conducteur  -visibility optimum by putting the cabin above the ground, and above the furrow or agricultural work done, the tools can be in front of the driver
-réglage de la hauteur du châssis pour s'adapter à toutes cultures -Adjustment of the chassis height to adapt to all cultures
-manoeuvrabilité totale en toutes directions. - total maneuverability in all directions.
