Description

Machine de travail, notamment du type déchaumeuse ou ameublisseur du sol, en particulier pour le travail sur une grande largeur  Work machine, particularly of the dethatcher type or soil loosener, in particular for working over a wide width
La présente invention concerne une machine de travail, notamment du type déchaumeuse ou ameublisseur du sol, en particulier pour le travail sur une grande largeur. The present invention relates to a working machine, particularly of the dethatcher or soil loosener type, in particular for working over a wide width.
Elle concerne plus particulièrement une machine de travail du sol du type comprenant un châssis portant au moins un timon d'attelage au véhicule, des moyens de relevage, un organe de référence et au moins une pluralité d'outils de travail du sol suivant un terrage réglable par l'intermédiaire de l'organe de référence, l'organe de référence de type rouleau tournant autour d'un axe, les moyens de relevage du châssis comportant au moins une paire de roues et étant aptes à faire passer le châssis d'une position de travail où l'organe de référence est au sol et où les roues sont relevées au-dessus du sol, à une position de transport où l'organe de référence est relevé au-dessus du sol et où les roues sont au sol. It relates more particularly to a tillage machine of the type comprising a chassis carrying at least one drawbar to the vehicle, lifting means, a reference member and at least a plurality of tillage tools in a soil adjustable by means of the reference member, the roll-type reference member rotating about an axis, the lifting means of the chassis comprising at least one pair of wheels and being able to pass the chassis of a working position where the reference member is on the ground and the wheels are raised above the ground, at a transport position where the reference member is raised above the ground and where the wheels are on the ground .
De telles machines posent un problème pour le travail d'une grande largeur de travail qui nécessite d'augmenter la longueur de la rangée d'outils de travail du sol. Jusqu'à présent, pour résoudre ce problème, les rangées d'outils sont constituées de sections de rangées articulées entre elles pour former, en position transport, une rangée d'outils par exemple en U. Comme l'illustre la demande internationale WO1991/003922. Le sectionnement des rangées et l'entraînement en déplacement desdites sections pour le passage d'une configuration alignée à une configuration par exemple en U rend complexe l'ensemble. En outre, à chaque ajout d'une section de rangées d'outils, il est nécessaire de revoir tout la conception de la machine. Dans de tels modes de réalisation, le timon est monté à pivotement autour d'un axe horizontal perpendiculaire à l'axe de rotation des roues de l'engin. Such machines pose a problem for working a large working width which requires increasing the length of the row of tillage tools. So far, to solve this problem, the rows of tools consist of sections of rows hinged together to form, in transport position, a row of tools for example U. As illustrated in the international application WO1991 / 003922. The cutting of the rows and the moving drive of said sections for the passage of an aligned configuration to a configuration for example in U complex complex. In addition, with each addition of a section of tool rows, it is necessary to review the entire design of the machine. In such embodiments, the drawbar is pivotally mounted about a horizontal axis perpendicular to the axis of rotation of the wheels of the machine.
Un but de la présente invention est donc de proposer une machine de travail du sol du type précité dont la conception permet, de manière simple, de faire varier la longueur de la rangée d'outils à l'intérieur d'une large plage. An object of the present invention is therefore to propose a working machine ground of the aforementioned type whose design allows, in a simple way, to vary the length of the row of tools within a wide range.
Un autre but de la présente invention est de proposer une machine du type précité dont la conception permet la réalisation d'un ensemble compact. Another object of the present invention is to provide a machine of the aforementioned type whose design allows the realization of a compact assembly.
A cet effet, l'invention a pour objet une machine de travail du sol tractée par un véhicule comprenant un châssis portant au moins un timon d'attelage au véhicule, des moyens de relevage, un organe de référence et au moins une pluralité d'outils de travail du sol suivant un terrage réglable par l'intermédiaire de l'organe de référence, l'organe de référence de type rouleau tournant autour d'un axe, les moyens de relevage du châssis comportant au moins une paire de roues et étant aptes à faire passer le châssis d'une position de travail où l'organe de référence est au sol et où les roues sont relevées au-dessus du sol, à une position de transport où l'organe de référence est relevé au-dessus du sol et où les roues sont au sol, caractérisée en ce que les roues des moyens de relevage ont leurs axes sensiblement orthogonaux à l'axe de rotation de l'organe de référence et en ce que le timon est monté mobile sur ledit châssis entre la position de travail où il est sensiblement parallèle aux axes de rotation des roues et sensiblement orthogonal à l'axe de rotation de l'organe de référence et la position de transport où il est sensiblement perpendiculaire aux axes de rotation des roues. For this purpose, the subject of the invention is a machine for tillage drawn by a vehicle comprising a chassis carrying at least one drawbar to the vehicle, lifting means, a reference member and at least a plurality of tillage tools according to an adjustable land by means of the reference member, the roller-type reference member rotating about an axis, the lifting means of the frame comprising at least one pair of wheels and being able to move the frame from a working position where the reference member is on the ground and where the wheels are raised above the ground, to a transport position where the reference member is raised above the ground and where the wheels are on the ground, characterized in that the wheels of the lifting means have their axes substantially orthogonal to the axis of rotation of the reference member and in that the drawbar is movably mounted on said frame between the working position o it is substantially parallel to the rotational axes of the wheels and substantially orthogonal to the axis of rotation of the reference member and the conveying position where it is substantially perpendicular to the wheel rotation axis.
Grâce au fait que le timon d'attelage est monté mobile sur le châssis entre la position de travail, dans laquelle il est sensiblement parallèle à l'axe de rotation des roues et sensiblement orthogonal à l'axe de rotation de l'organe de référence et exerce sur le châssis un effort de traction transversal à l'axe de rotation de l'organe de référence et parallèle à l'axe des roues, et la position de transport dans laquelle il est sensiblement perpendiculaire aux axes des roues et exerce sur le châssis un effort de traction dit axial suivant une direction générale sensiblement parallèle à l'axe de rotation de l'organe de référence et sensiblement orthogonale à l'axe de rotation des roues, la longueur des rangées d'outils est uniquement limitée par la longueur autorisée des véhicules sur route, cette longueur n'étant pas limitée dans certains pays. Thanks to the fact that the drawbar is movably mounted on the chassis between the working position, in which it is substantially parallel to the axis of rotation of the wheels and substantially orthogonal to the axis of rotation of the reference member and exerts on the chassis a traction force transverse to the axis of rotation of the reference member and parallel to the axis of the wheels, and the transport position in which it is substantially perpendicular to the axes of the wheels and exerts on the chassis a traction force said axial in a general direction substantially parallel to the axis of rotation of the reference member and substantially orthogonal to the axis of rotation of the wheels, the length of Rows of tools is only limited by the permitted length of road vehicles, this length being not limited in some countries.
De préférence, au moins une partie des outils de travail du sol étant organisés en une ou plusieurs rangées d'outils s'étendant de préférence sensiblement parallèlement à l'axe de rotation de l'organe de référence, l'une des roues de relevage de la ou d'au moins l'une des paires de roues s'étend, en position basse d'appui au sol, entre l'organe de référence et une rangée d'outils de travail du sol. Preferably, at least a portion of the tillage tools being organized in one or more rows of tools preferably extending substantially parallel to the axis of rotation of the reference member, one of the lifting wheels the or at least one of the pairs of wheels extends, in the low position of support to the ground, between the reference member and a row of soil working tools.
Les roues de relevage d'au moins une paire de roues s'étendent donc, de préférence, de part et d'autre de la ou des rangées d'outils avec l'une des roues de la paire de roues disposée entre l'organe de référence et la rangée d'outils, la plus proche de l'organe de référence. Cette configuration permet de réduire la compacité de l'ensemble en position transport par relevage de l'organe de référence. The lifting wheels of at least one pair of wheels preferably extend, preferably, on either side of the row or rows of tools with one of the wheels of the pair of wheels arranged between the body reference and the row of tools, the closest to the reference member. This configuration makes it possible to reduce the compactness of the assembly in the transport position by raising the reference member.
Ainsi, de préférence, en position de transport du châssis, l'organe de référence présente au moins une position haute écartée du sol dans laquelle il s'étend dans la largeur de la voie délimitée par ladite au moins une paire de roues de relevage. Thus, preferably, in the chassis transport position, the reference member has at least one high position spaced from the ground in which it extends in the width of the track delimited by said at least one pair of lifting wheels.
Généralement, l'organe de référence est couplé à pivotement au châssis par une liaison à pivotement autour d'un axe sensiblement parallèle à l'axe de rotation de l'organe de référence pour le passage dudit organe de référence d'une position basse d'appui au sol correspondant à la position de travail du châssis à une position haute écartée du sol correspondant à la position de transport du châssis dans laquelle il est apte à s'étendre dans la largeur de la voie délimitée par ladite au moins une paire de roues de relevage. Generally, the reference member is pivotally coupled to the frame by a connection pivotally about an axis substantially parallel to the axis of rotation of the reference member for the passage of said reference member from a low position of ground support corresponding to the working position of the frame at a high position spaced from the ground corresponding to the transport position of the frame in which it is able to extend in the width of the track delimited by said at least one pair of lifting wheels.
En position de travail du châssis, l'organe de référence s'étend derrière la ou les rangées d'outils pris dans le sens d'avancement de la machine. En position de transport du châssis, l'organe de référence s'étend à côté ou au-dessus de la ou les rangées d'outils. In the working position of the frame, the reference member extends behind the row or rows of tools taken in the direction of advance of the machine. In position transporting the frame, the reference member extends next to or above the row or rows of tools.
De préférence, le timon d'attelage est monté sur le châssis mobile à pivotement autour d'un axe dit vertical orthogonal à l'axe de l'organe de référence et à l'axe de rotation des roues. Preferably, the drawbar is mounted on the movable frame pivotally about a so-called vertical axis orthogonal to the axis of the reference member and the axis of rotation of the wheels.
De préférence, la machine de travail du sol comporte au moins deux paires de roues de relevage à axes de rotation sensiblement parallèles, chaque roue d'une paire de roues formant avec la roue de l'autre paire de roues un ensemble de roues à balancier. Cette disposition permet une répartition au sol de la charge du châssis. Preferably, the tillage machine comprises at least two pairs of lifting wheels with substantially parallel axes of rotation, each wheel of a pair of wheels forming with the wheel of the other pair of wheels a set of balance wheels. . This arrangement allows a distribution on the ground of the chassis load.
De préférence, la ou chaque paire de roues de relevage est couplée au châssis par une structure de liaison montée à pivotement sur le châssis autour d'un axe horizontal sensiblement orthogonal à l'axe de rotation de l'organe de référence. Preferably, the or each pair of lifting wheels is coupled to the frame by a connecting structure mounted to pivot on the frame about a horizontal axis substantially orthogonal to the axis of rotation of the reference member.
La structure de liaison est donc montée à pivotement sur le châssis autour d'un axe sensiblement parallèle à l'axe de rotation des roues de relevage et orthogonal à l'axe de rotation de l'organe de référence. The connecting structure is pivotally mounted on the frame about an axis substantially parallel to the axis of rotation of the lifting wheels and orthogonal to the axis of rotation of the reference member.
De préférence, la structure de liaison comprend une pièce de type pont, de préférence en forme générale d'arceau, reliant lesdites roues de relevage d'une paire de roues entre elles et au moins un bras de liaison de la pièce de type pont au châssis, ledit au moins un bras étant monté à pivotement sur ledit châssis. Preferably, the connecting structure comprises a bridge-type piece, preferably in the general shape of a bow, connecting said lifting wheels of a pair of wheels together and at least one connecting arm of the bridge-type piece to frame, said at least one arm being pivotally mounted on said frame.
La forme en arceau de la pièce de liaison de type pont permet de limiter les conflits avec le châssis lors de l'entraînement en déplacement des roues de relevage pour le passage d'une position haute à une position basse. De préférence, le châssis porte-outils, dont au moins une partie des outils de travail du sol sont organisés en une ou plusieurs rangées s'étendant de préférence sensiblement parallèlement à l'axe de rotation de l'organe de référence, comprend, pour chaque rangée d'outils, au moins une poutre à laquelle les outils sont couplés, de préférence par un dispositif de sécurité, ladite poutre étant formée de sections de poutres montées mobiles l'une par rapport à l'autre à pivotement autour d'un arbre d'axe horizontal transversal à l'axe longitudinal de la poutre pour permettre auxdits outils desdites sections de poutre de suivre le profil du sol, lesdites sections de poutres étant reliées l'une à l'autre par des moyens élastiquement déformables tendant à rappeler les sections d'extrémité de la poutre en direction du sol. Il en résulte un meilleur travail du sol. The arch form of the bridge-type connecting piece makes it possible to limit conflicts with the chassis when driving the lifting wheels to move from a high position to a low position.

This results in better tillage.

Comme mentionné ci-dessus, la machine de travail du sol, objet de l'invention, est destinée à être tractée par un véhicule tracteur. Cette machine est de préférence plus particulièrement destinée à ameublir ou à déchaumer le sol. Cette machine comprend un châssis 1 portant au moins un organe 4 de référence. L'organe 4 de référence est un organe rotatif de type rouleau tournant autour d'un axe YY'. Dans l'exemple représenté, l'organe de référence est formé d'une juxtaposition de tronçons de rouleaux, en l'occurrence de type cage tournant chacun autour d'un axe, lesdits axes étant sensiblement confondus. De manière équivalente, l'organe de référence aurait pu être formé d'un rouleau unique. Lesdits tronçons de rouleaux sont montés à rotation entre deux flasques. Ces flasques sont couplés à une poutre elle-même reliée au châssis par au moins un bras pivotant autour d'un axe parallèle à l'axe de rotation des tronçons de rouleau. Le déplacement à pivotement des bras s'opère en synchronisme à l'aide de vérins 14 s'étendant entre châssis et bras, Ainsi, l'organe 4 de référence est apte à passer d'une position basse à une position haute et inversement, lors de l'actionnement des vérins 14. As mentioned above, the soil working machine, object of the invention, is intended to be towed by a tractor vehicle. This machine is preferably more particularly intended to loosen or loosen the soil. This machine comprises a frame 1 carrying at least one reference member 4. The reference member 4 is a rotary member of the roll type rotating around an axis YY '. In the example shown, the reference member is formed of a juxtaposition of roller sections, in this case of cage type each rotating about an axis, said axes being substantially merged. Equivalently, the reference member could have been formed of a single roll. Said sections of rollers are rotatably mounted between two flanges. These flanges are coupled to a beam itself connected to the frame by at least one arm pivoting about an axis parallel to the axis of rotation of the roll sections. The pivoting movement of the arms is effected in synchronism by means of jacks 14 extending between frame and arm. Thus, the reference member 4 is able to move from a low position to a high position and vice versa. when actuating the cylinders 14.
Le châssis 1 de la machine de travail porte encore des moyens de relevage. Les moyens de relevage du châssis 1 comportant au moins une paire de roues 5, 6 et étant aptes à faire passer le châssis 1 d'une position de travail où l'organe 4 de référence est au sol et où les roues 5, 6 sont relevées au-dessus du sol, à une position de transport où l'organe 4 de référence est relevé au- dessus du sol et où les roues 5, 6 sont au sol. Le châssis porte encore au moins une pluralité d'outils 3 de travail du sol suivant un terrage réglable par l'intermédiaire de l'organe 4 de référence. Ces outils sont de préférence des outils de type disque ou lame. Au moins une partie de ces outils sont organisés en une ou plusieurs rangées d'outils d'axe sensiblement parallèle à l'axe de rotation de l'organe 4 de référence. The chassis 1 of the working machine still carries lifting means. The lifting means of the frame 1 comprising at least one pair of wheels 5, 6 and being able to move the frame 1 of a working position where the reference member 4 is on the ground and where the wheels 5, 6 are raised above the ground, at a transport position where the reference member 4 is raised above the ground and where the wheels 5, 6 are on the ground. The frame still carries at least a plurality of tillage tools 3 according to an adjustable land by means of the reference member 4. These tools are preferably tools of disk or blade type. At least a portion of these tools are organized in one or more rows of axis tools substantially parallel to the axis of rotation of the reference member 4.
Dans les exemples représentés, le châssis comporte deux rangées de disques concaves à concavité inversée d'une rangée de disques à une autre. In the examples shown, the frame has two rows of concave concave disks inverted from one row of disks to another.
Le châssis 1 porte-outils, dont au moins une partie des outils 3 de travail du sol sont organisés en une ou plusieurs rangées 3 s'étendant de préférence sensiblement parallèlement à l'axe YY' de rotation de l'organe 4 de référence, comprend, pour chaque rangée d'outils 3, au moins une poutre 8 à laquelle les outils 3 sont couplés, de préférence par un dispositif 10 de sécurité. Ladite poutre 8 est formée de sections de poutre montées mobiles l'une par rapport à l'autre à pivotement autour d'un arbre 9 d'axe horizontal transversal à l'axe longitudinal de la poutre 8. L'arbre 9 s'étend donc orthogonalement à l'axe de rotation de l'organe 4 de référence et parallèlement à l'axe des roues pour permettre auxdits outils 3 desdites sections de poutre de suivre le profil du sol. Les sections de poutres sont reliées l'une à l'autre par des moyens 1 1 élastiquement déformables tendant à rappeler les sections d'extrémité de la poutre 8 en direction du sol. The frame 1 tool holder, at least a portion of the tools 3 tillage are organized in one or more rows 3 extending preferably substantially parallel to the axis YY 'of rotation of the member 4 reference, comprises, for each row of tools 3, at least one beam 8 to which the tools 3 are coupled, preferably by a safety device 10. Said beam 8 is formed of beam sections mounted movable relative to each other to pivot about a shaft 9 of horizontal axis transverse to the longitudinal axis of the beam 8. The shaft 9 extends therefore orthogonal to the axis of rotation of the reference member 4 and parallel to the axis of the wheels to allow said tools 3 of said beam sections to follow the profile of the ground. The beam sections are connected to each other by means 1 1 elastically deformable tending to recall the end sections of the beam 8 in the direction of the ground.
Le dispositif de sécurité reliant chaque outil 3 à la poutre 8 est formé d'un ressort hélicoïdal assurant la liaison de l'outil de travail du sol à l'une des poutres du châssis 1 . Ce dispositif de sécurité ne sera pas décrit en détail car il est bien connu à ceux versés dans cet art. Grâce à la présence de dispositif de sécurité au niveau de chaque outil de travail du sol, chaque outil est apte à s'escamoter lors de la rencontre avec un obstacle au cours de l'avancement du châssis en position travail. The safety device connecting each tool 3 to the beam 8 is formed of a helical spring ensuring the connection of the soil working tool to one of the beams of the frame 1. This safety device will not be described in detail because it is well known to those skilled in the art. Thanks to the presence of safety device at each tillage tool, each tool is able to retract when encountering an obstacle during the advancement of the frame in working position.
En position travail du châssis, l'organe 4 de référence s'étend derrière la ou les rangées 3 d'outils pris dans le sens d'avancement de la machine. Ainsi, dans l'exemple représenté, le châssis comporte, en position travail, une première rangée d'outils, dite rangée avant d'outils de travail du sol, une rangée arrière d'outils de travail du sol et l'organe 4 de référence. En position transport du châssis, l'organe de référence s'étend à côté ou au-dessus de la ou les rangées d'outils. In the working position of the frame, the reference member 4 extends behind the row or rows 3 of tools taken in the direction of advance of the machine. Thus, in the example shown, the frame comprises, in working position, a first row of tools, called the front row of tillage tools, a rear row of tillage tools and the body 4 of reference. In the transport position of the frame, the reference member extends next to or above the row or rows of tools.
Le châssis 1 porte encore au moins un timon 2 d'attelage au véhicule qui sera décrit ci-après. De manière caractéristique à l'invention, les roues 5, 6 des moyens de relevage ont leurs axes ZZ' sensiblement orthogonaux à l'axe YY' de rotation de l'organe 4 de référence et le timon 2 est monté mobile sur ledit châssis 2 entre la position de travail où il est sensiblement orthogonal à l'axe YY' de rotation de l'organe 4 de référence et la position de transport où il est sensiblement perpendiculaire aux axes ZZ' de rotation des roues 5, 6. Dans l'exemple représenté, la machine de travail du sol comporte au moins deux paires de roues 5, 6 de relevage à axes de rotation sensiblement parallèles, chaque roue 5, 6 d'une paire de roues formant avec la roue 5, 6 de l'autre paire de roues un ensemble de roues à balancier. En particulier, l'une des roues de relevage de la ou d'au moins l'une des paires de roues, représentée en 6 aux figures, s'étend en position basse d'appui au sol entre l'organe 4 de référence et une rangée d'outils 3. The frame 1 still carries at least one drawbar 2 coupling to the vehicle which will be described below. In a manner characteristic of the invention, the wheels 5, 6 of the lifting means have their axes ZZ 'substantially orthogonal to the axis YY' of rotation of the reference member 4 and the drawbar 2 is movably mounted on said frame 2 between the working position where it is substantially orthogonal to the axis YY 'of rotation of the reference member 4 and the transport position where it is substantially perpendicular to the axes ZZ' of rotation of the wheels 5, 6. In the As shown, the tillage machine comprises at least two pairs of wheels 5, 6 for lifting substantially parallel axes of rotation, each wheel 5, 6 of a pair of wheels forming with the wheel 5, 6 of the other pair of wheels a set of pendulum wheels. In particular, one of the lifting wheels of the or at least one of the pairs of wheels, shown at 6 in the figures, extends in the low position of support to the ground between the reference member 4 and a row of tools 3.
Pour permettre le relevage des roues, la ou chaque paire de roues 5, 6 de relevage est couplée au châssis 1 par une structure 7 de liaison montée à pivotement sur le châssis 1 autour d'un axe WW horizontal sensiblement orthogonal à l'axe YY' de rotation de l'organe 4 de référence. To allow the lifting of the wheels, the or each pair of wheels 5, 6 lifting is coupled to the frame 1 by a connecting structure 7 pivotally mounted on the frame 1 about a horizontal axis WW substantially orthogonal to the axis YY of rotation of the reference member 4.
La structure 7 de liaison comprend une pièce 71 de type pont en forme générale d'arceau reliant lesdites roues 5, 6 de relevage d'une paire de roues entre elles et deux bras 72 de liaison de la pièce 71 de type pont au châssis 1 . Les bras 72 s'étendent de part et d'autre d'une poutre constitutive du châssis 1 et sont montés à pivotement sur ledit châssis 1 . The connecting structure 7 comprises a bridge-like piece 71 of the generally hoop-type connecting said wheels 5, 6 for lifting a pair of wheels together and two arms 72 for connecting the bridge-type part 71 to the chassis 1 . The arms 72 extend on either side of a constituent beam of the frame 1 and are pivotally mounted on said frame 1.
Le timon 2 d'attelage, qui se présente sous forme d'un bras, est quant à lui monté mobile entre une position de travail dans laquelle il est apte à exercer sur le châssis un effort de traction transversal à l'axe de rotation de l'organe de référence, et une position de transport dans laquelle il est apte à exercer sur le châssis un effort de traction dit axial suivant une direction générale sensiblement parallèle à l'axe de rotation de l'organe de référence ou sensiblement orthogonale à l'axe de rotation des roues. The drawbar 2, which is in the form of an arm, is itself movably mounted between a working position in which it is able to exert on the chassis a tensile force transverse to the axis of rotation of the reference member, and a transport position in which it is able to exert on the chassis a traction force said axial in a general direction substantially parallel to the axis of rotation of the reference member or substantially orthogonal to the axis of rotation of the wheels.
En particulier, le timon 2 d'attelage est monté sur le châssis 1 , mobile à pivotement autour d'un axe dit vertical perpendiculaire à l'axe de l'organe 4 de référence et à l'axe de rotation des roues 5, 6. La machine comporte, pour le passage du timon 2 d'attelage de la position de travail à la position de transport et inversement, un actionneur 12, de type vérin, disposé entre le timon 2 d'attelage et le châssis 1 . Le timon d'attelage est équipé à son extrémité libre d'un attelage, tel qu'un attelage trois points pour un couplage à un véhicule tracteur. In particular, the drawbar 2 is mounted on the chassis 1, mobile to pivoting about a so-called vertical axis perpendicular to the axis of the reference member 4 and the axis of rotation of the wheels 5, 6. The machine comprises, for the passage of the drawbar 2 coupling of the position of working in the transport position and conversely, an actuator 12, of the jack type, arranged between the drawbar 2 and the chassis 1. The drawbar is equipped at its free end with a hitch, such as a three-point hitch for coupling to a towing vehicle.
Le fonctionnement d'une telle machine est le suivant. La machine est attelée à un véhicule tracteur dans une configuration conforme à la figure 3 et correspondant à la position de transport du châssis dans laquelle le timon 2 d'attelage est apte à exercer un effort axial, c'est-à-dire sensiblement parallèle à l'axe de rotation de l'organe de référence et orthogonal à l'axe de rotation des roues sur le châssis 1 . L'organe 4 de référence et les outils 3 de travail du sol sont en position écartée du sol et les roues 5 et 6 sont en position d'appui au sol de sorte que la machine se déplace par appui roulant sur lesdites roues avec un encombrement en largeur correspondant à la voie délimitée par les roues puisque l'organe 4 de référence est relevé et disposé dans la largeur de ladite voie. Lors d'une arrivée dans le champ, le vérin 12 d'entraînement en déplacement du timon d'attelage est actionné pour un déplacement relatif à pivotement entre châssis et timon jusqu'à la position de travail conforme à la figure 1 dans laquelle le timon exerce sur le châssis 1 un effort de traction suivant une direction générale orthogonale à l'axe de rotation de l'organe de référence et parallèle à l'axe des roues. L'organe 4 de référence est amené en appui au sol par les vérins 14 et les roues 5, 6 sont relevées à l'aide du ou des vérins 13. Dans cette position de travail, les outils de travail du sol peuvent, en fonction de la position de l'organe 4 de référence, être disposés au niveau du sol comme l'illustre la figure 5 ou au-dessus du sol comme l'illustre la figure 4 où la machine est en bout de champ. La largeur travaillée à l'aide des outils 3 de travail du sol peut être comprise entre 3 mètres et 20 mètres. The operation of such a machine is as follows. The machine is coupled to a towing vehicle in a configuration according to Figure 3 and corresponding to the transport position of the frame in which the drawbar 2 is able to exert an axial force, that is to say substantially parallel to the axis of rotation of the reference member and orthogonal to the axis of rotation of the wheels on the frame 1. The reference member 4 and the tillage tools 3 are in a position away from the ground and the wheels 5 and 6 are in the ground support position so that the machine moves by rolling support on said wheels with a space requirement. width corresponding to the track defined by the wheels since the reference member 4 is raised and disposed in the width of said path. Upon arrival in the field, the cylinder 12 for driving the displacement of the drawbar is actuated for a relative displacement pivoting between frame and drawbar to the working position according to Figure 1 in which the drawbar exerts on the frame 1 a traction force in a general direction orthogonal to the axis of rotation of the reference member and parallel to the axis of the wheels. The reference member 4 is brought to bear on the ground by the jacks 14 and the wheels 5, 6 are raised with the aid of the jacks 13. In this working position, the tillage tools can, depending the position of the reference member 4, be arranged at ground level as shown in Figure 5 or above the ground as shown in Figure 4 where the machine is at the end of field. The width worked using tools 3 tillage can be between 3 meters and 20 meters.
Cette largeur de travail a, en position de transport du châssis, une incidence sur la longueur de la machine mais en aucun cas sur la largeur de ladite machine de sorte que le transport sur route de ladite machine est facilité. This working width has, in the chassis transport position, an impact on the length of the machine but in no case on the width of said machine so that the transport on the road of said machine is facilitated.
Lorsque le travail dans le champ est terminé, les roues 5 et 6 sont de nouveau abaissées, l'organe 4 de référence est relevé et le châssis et le timon sont animés d'un déplacement relatif à pivotement pour le retour de la machine dans une position de transport du châssis. When the work in the field is completed, the wheels 5 and 6 are lowered again, the reference member 4 is raised and the frame and the drawbar are moved relative to pivoting for the return of the machine in a transport position of the chassis.
