Un autre but de l'invention est de proposer un engin dont la conception permet une conduite aisée, sans effort, et un passage dans des zones à voie de circulation de faible largeur et de profil complexe. Another object of the invention is to provide a machine whose design allows easy driving, effortlessly, and a passage in traffic lane areas of small width and complex profile.
À cet effet, l'invention a pour objet un engin roulant notamment pour la dépose au sol, sous forme d'un lit, de matériaux en vrac, ledit engin comprenant un châssis roulant équipé d'un réservoir de stockage et de distribution des matériaux en vrac et d'une table de lissage, la table de lissage présentant un bord d'attaque disposé, transversalement au sens de déplacement de l'engin, c'est-à-dire suivant la largeur de l'engin et ledit réservoir étant muni, en partie inférieure formant fond du réservoir, d'une ouverture de déchargement disposée entre le bord d'attaque de la table de lissage et les roues du châssis roulant de l'engin, en vue de la dépose d'un lit de matériau en vrac d'épaisseur contrôlée, caractérisé en ce que le châssis roulant est monté à basculement autour de l'axe de rotation des roues par l'intermédiaire desquelles il repose au sol pour le passage dudit engin d'une configuration dite de travail dans laquelle la table de lissage est en contact d'appui avec le sol à une configuration dite de transport dans laquelle la table de lissage est écartée du sol, en ce que les roues du châssis roulant sont des roues motrices, et en ce que le réservoir et la table de lissage forment un ensemble mobile réglable en position par l'intermédiaire de moyens de réglage configurés pour permettre, au moins dans la position dans laquelle les roues du châssis roulant reposent sur un sol plan horizontal et la table de lissage s'étend parallèlement au sol, à écartement du sol, d'une part, un réglage en hauteur de la table de lissage et de l'ouverture de déchargement par déplacement en monte ou baisse dudit ensemble dans le sens d'un écartement ou d'un rapprochement du sol, d'autre part, un réglage en inclinaison de la table de lissage de manière à former un angle non nul entre le plan de la table de lissage et l'axe de rotation des roues. 3 To this end, the subject of the invention is a rolling machine, in particular for the laying on the ground, in the form of a bed, of bulk materials, said machine comprising a rolling frame equipped with a storage and material distribution tank. in bulk and a smoothing table, the smoothing table having a leading edge disposed transversely to the direction of movement of the machine, that is to say according to the width of the machine and said tank being equipped, at the lower part forming a bottom of the tank, with an unloading opening arranged between the leading edge of the smoothing table and the wheels of the rolling chassis of the machine, for the purpose of removing a bed of material in bulk of controlled thickness, characterized in that the rolling frame is mounted to tilt around the axis of rotation of the wheels through which it rests on the ground for the passage of said machine of a so-called working configuration in which the smoothing table is in con ground support to a so-called transport configuration in which the smoothing table is spaced from the ground, in that the wheels of the rolling frame are driving wheels, and in that the reservoir and the smoothing table form a movable assembly adjustable in position by means of adjusting means configured to allow, at least in the position in which the wheels of the rolling frame rest on a horizontal plane ground and the smoothing table extends parallel to the ground, spaced from the floor, on the one hand, a height adjustment of the smoothing table and the unloading opening by moving upward or downward of said assembly in the direction of spacing or bringing the ground closer, on the other hand , a tilting adjustment of the smoothing table so as to form a non-zero angle between the plane of the smoothing table and the axis of rotation of the wheels. 3
Le montage à pivotement du châssis portant le réservoir et la table de lissage autour de l'axe de rotation des roues du châssis permet l'utilisation de la table de lissage comme moyen d'appui sur la surface venant d'être revêtue, tout en suivant le profil du sol. Le réglage en inclinaison de la table de lissage avec le plan de l'ouverture de déchargement du réservoir suivant cette inclinaison permet à l'ouverture de déchargement de ne pas constituer un obstacle lors de l'avancement de l'engin. Le réglage en inclinaison de la table de lissage, au moins par pivotement de la table de lissage autour d'un axe, parallèle au plan de la table de lissage, et transversal, en particulier orthogonal à l'axe de rotation des roues, de manière à former, entre le plan de la table de lissage et l'axe de rotation des roues, un angle aigu d'un côté ou de l'autre de l'engin suivant la déclivité du sol, permet de maintenir l'horizontalité de la table de lissage, en l'absence d'une planéité du sol. Le réglage en hauteur de la table de lissage et de l'ouverture de déchargement par rapport au plan d'appui au sol des roues du châssis permet l'obtention d'un lit d'épaisseur souhaitée.  The pivotal mounting of the frame carrying the reservoir and the smoothing table around the axis of rotation of the wheels of the frame allows the use of the smoothing table as a means of support on the surface that has just been coated, while following the soil profile. The inclination adjustment of the smoothing table with the plane of the unloading opening of the tank following this inclination allows the unloading opening not to be an obstacle during the advancement of the machine. The inclination adjustment of the smoothing table, at least by pivoting the smoothing table about an axis, parallel to the plane of the smoothing table, and transverse, in particular orthogonal to the axis of rotation of the wheels, so as to form, between the plane of the smoothing table and the axis of rotation of the wheels, an acute angle of one side or the other of the machine according to the gradient of the ground, makes it possible to maintain the horizontality of the smoothing table, in the absence of flatness of the ground. Adjusting the height of the smoothing table and the unloading opening relative to the ground support plane of the wheels of the frame makes it possible to obtain a bed of desired thickness.
Selon un mode de réalisation, les moyens de réglage configurés pour un réglage en hauteur et en inclinaison de la table de lissage sont au moins partiellement communs. Selon un mode de réalisation, les moyens de réglage comprennent deux actionneurs à actionnement indépendant disposés chacun entre le châssis et l'ensemble mobile. According to one embodiment, the adjustment means configured for adjustment in height and inclination of the smoothing table are at least partially common. According to one embodiment, the adjustment means comprise two independently actuated actuators each disposed between the frame and the moving assembly.
Selon un mode de réalisation, chaque actionneur est un vérin dont la tige est fixée au châssis et dont le corps est fixé par l'intermédiaire d'un bras audit ensemble mobile. According to one embodiment, each actuator is a cylinder whose rod is fixed to the frame and whose body is fixed by means of an arm to said moving assembly.
Selon un mode de réalisation, l'axe longitudinal de chaque vérin s'étend orthogonalement à l'axe de rotation des roues. 4 According to one embodiment, the longitudinal axis of each cylinder extends orthogonally to the axis of rotation of the wheels. 4
Cet axe longitudinal de chaque vérin s'étend, de préférence, sensiblement orthogonalement, c'est-à-dire à plus ou moins 10° près, au plan de la table de lissage.  This longitudinal axis of each cylinder preferably extends substantially orthogonally, that is to say more or less 10 °, to the plane of the smoothing table.
Selon un mode de réalisation, l'un des bras et ledit ensemble mobile sont couplés l'un à l'autre par une liaison pivot d'axe transversal à l'axe de rotation des roues et parallèle au plan de la table de lissage et l'autre des bras et ledit ensemble sont couplés l'un à l'autre par une liaison à pivotement et à coulissement, le coulissement étant apte à s'opérer suivant une direction parallèle au bord d'attaque de la table de lissage. L'utilisation, en tant qu'actionneurs, de vérins pouvant être pilotés par le conducteur de l'engin permet un réglage permanent, y compris pendant la conduite de l'engin. Le conducteur a ainsi la possibilité de procéder en temps réel et en continu à un réglage de la position de la table de lissage, lorsqu'il constate un problème. Selon un mode de réalisation, l'engin est équipé d'un guidon en U, les branches du U couplant l'âme du U formant poignée aux vérins, et l'une des branches du U est couplée à l'un des vérins de manière déplaçable à coulissement le long dudit vérin. Le déplacement à coulissement évite une torsion du guidon lors de la commande d'une variation de longueur des vérins avec un réglage en longueur des vérins différencié d'un vérin à l'autre. According to one embodiment, one of the arms and said movable assembly are coupled to each other by a pivot link axis transverse to the axis of rotation of the wheels and parallel to the plane of the smoothing table and the other arm and said assembly are coupled to each other by a connection to pivoting and sliding, the sliding being adapted to operate in a direction parallel to the leading edge of the smoothing table. The use, as actuators, of cylinders that can be controlled by the driver of the machine allows a permanent adjustment, including while driving the machine. The driver thus has the possibility of real-time and continuous adjustment of the position of the smoothing table, when he finds a problem. According to one embodiment, the machine is equipped with a U-shaped handlebar, the branches of the U coupling the core of the U forming a handle to the jacks, and one of the branches of the U is coupled to one of the jacks of slidingly movable manner along said cylinder. The sliding movement avoids a torsion of the handlebars when controlling a variation in the length of the cylinders with a length adjustment cylinders differentiated from one jack to the other.
Selon un mode de réalisation, le réservoir ouvert par le dessus est délimité par une paroi transversale dite avant, une paroi transversale dite arrière, et deux parois longitudinales dites latérales, le bord d'attaque de la table s'étend à la base de la paroi arrière du réservoir et l'ouverture de déchargement est une ouverture obturable. Il est ainsi possible de remplir le réservoir de l'engin en un lieu éloigné de la surface à revêtir d'un lit de matériaux en vrac. According to one embodiment, the tank opened from above is delimited by a so-called front transverse wall, a so-called rear transverse wall, and two so-called lateral lateral walls, the leading edge of the table extends to the base of the rear wall of the tank and the unloading opening is a closable opening. It is thus possible to fill the tank of the machine at a place remote from the surface to be coated with a bed of bulk materials.
Selon un mode de réalisation, le réservoir est compartimenté par des cloisons s'étendant parallèlement à l'axe longitudinal de l'engin pris suivant la direction 5 According to one embodiment, the tank is compartmentalized by partitions extending parallel to the longitudinal axis of the machine taken in the direction 5
de déplacement de l'engin, les moyens d'obturation de l'ouverture de déchargement comprennent une série de trappes disposées côte à côte dans le sens de la largeur de l'engin, lesdites trappes étant montées mobiles entre une position fermée de l'ouverture de déchargement dans laquelle lesdites trappes sont séparées l'une de l'autre par une cloison et une position ouverte de l'ouverture de déchargement dans laquelle lesdites trappes font au moins partiellement saillie dudit réservoir, au moins l'une des trappes étant apte à se déplacer entre la position fermée et la position ouverte indépendamment des autres trappes et l'engin est équipé d'une butée de fin de course des trappes en position ouverte, cette butée de fin de course étant réglable en position. La présence d'une pluralité de trappes à l'intérieur d'un réservoir compartimenté permet de réduire la largeur de travail et/ou le débit de distribution. for moving the machine, the closing means of the unloading opening comprise a series of traps arranged side by side in the direction of the width of the machine, said traps being movably mounted between a closed position of the unloading opening in which said hatches are separated from each other by a partition and an open position of the unloading opening in which said hatches at least partially project from said tank, at least one of the traps being suitable to move between the closed position and the open position independently of the other hatches and the machine is equipped with an end stop of the hatches in the open position, this end stop being adjustable in position. The presence of a plurality of hatches inside a compartmentalized tank makes it possible to reduce the working width and / or the distribution flow rate.
Selon un mode de réalisation, le réservoir comprend deux volets de réglage de la largeur du lit de matériaux en vrac à déposer, chaque volet s'étendant au- dessous des moyens d'obturation de l'ouverture de déchargement en position fermée de ladite ouverture de déchargement, chaque volet étant au niveau de son bord dit supérieur couplé à une paroi latérale du réservoir par une liaison pivot d'axe de pivotement parallèle au plan de la table de lissage pour le passage dudit volet d'une position en applique contre ladite paroi latérale à une position écartée de ladite paroi latérale. Ces volets participent donc également au réglage de la largeur de travail. According to one embodiment, the reservoir comprises two flaps for adjusting the width of the bed of bulk materials to be deposited, each flap extending below the means for closing the unloading opening in the closed position of said opening. unloading, each flap being at its upper edge coupled to a side wall of the reservoir by a swivel axis pivot connection parallel to the plane of the smoothing table for the passage of said flap from a position to apply against said side wall at a position spaced from said side wall. These flaps therefore also contribute to the adjustment of the working width.

Comme mentionné ci-dessus, l'invention a pour objet un engin 1 roulant automoteur pour la dépose au sol, sous forme d'un lit ou couche, de matériaux en vrac de revêtement pour routes, chaussées ou autres surfaces. Ces matériaux en vrac peuvent être formés par de l'asphalte, du sable, des gravillons ou autres. As mentioned above, the object of the invention is a self-propelled machine 1 for the laying on the ground, in the form of a bed or a layer, of bulk coating materials for roads, roadways or other surfaces. These bulk materials can be formed by asphalt, sand, gravel or other.
Cet engin 1 est un engin 1 automoteur comprenant un châssis 2 équipé de deux roues 8 d'appui au sol. Ces roues 8 sont des roues motrices entraînées à rotation autour d'un axe XX'. Pour permettre cet entraînement moteur en rotation des roues, l'engin est équipé d'un pont hydrostatique auquel chaque roue 8 est couplée par un demi-arbre, ce pont hydrostatique intégrant un différentiel et étant couplé à un moteur thermique. Ces moyens moteurs d'entraînement en rotation des roues ne seront pas décrits plus en détail, car ils sont bien connus à ceux versés dans cet art. This machine 1 is a self-propelled machine 1 comprising a chassis 2 equipped with two wheels 8 ground support. These wheels 8 are driven wheels rotated about an axis XX '. To allow this motor drive in rotation of the wheels, the machine is equipped with a hydrostatic bridge to which each wheel 8 is coupled by a half-shaft, this hydrostatic bridge incorporating a differential and being coupled to a heat engine. These drive means for rotating the wheels will not be described in more detail, as they are well known to those skilled in the art.
D'autres moyens moteurs d'entraînement en rotation des roues, tels qu'un moteur électrique alimenté par une batterie, auraient pu être envisagés sans sortir du cadre de l'invention. En particulier, l'essieu aurait pu être réalisé d'un seul tenant et non brisé comme dans l'exemple représenté. L'engin comprend encore un réservoir 3 de stockage et de distribution des matériaux en vrac destinés à former ledit revêtement, et une table 4 de lissage, le réservoir 3 de stockage et la table 4 de lissage étant montés sur le châssis 2. Other wheel drive means, such as an electric motor powered by a battery, could have been envisaged without departing from the scope of the invention. In particular, the axle could have been made in one piece and not broken as in the example shown. The machine further comprises a tank 3 for storing and dispensing bulk materials intended to form said coating, and a smoothing table 4, the storage tank 3 and the smoothing table 4 being mounted on the frame 2.
Dans l'exemple représenté, la table 4 de lissage présente un bord 5 d'attaque disposé transversalement au sens de déplacement de l'engin, c'est-à-dire suivant la largeur de l'engin 1 , et le réservoir 3 est muni, en partie inférieure formant fond 6 du réservoir 3, d'une ouverture 7 de déchargement disposée entre le bord 5 d'attaque de la table 4 de lissage et les roues 8 du châssis 2 8 In the example shown, the smoothing table 4 has a leading edge disposed transversely to the direction of movement of the machine, that is to say along the width of the machine 1, and the reservoir 3 is equipped, in the lower part forming a bottom 6 of the tank 3, with an unloading opening 7 arranged between the leading edge 5 of the smoothing table 4 and the wheels 8 of the frame 2 8
roulant de l'engin 1 . En particulier, le réservoir 3 ouvert par le dessus est, à la manière d'une trémie, délimité par une paroi 18 transversale dite avant, une paroi 19 transversale dite arrière et deux parois 20 longitudinales dites latérales. Le bord 5 d'attaque de la table 4 de lissage s'étend à la base de la paroi 19 arrière du réservoir 3 et l'ouverture 7 de déchargement du réservoir 3 est une ouverture obturable. rolling gear 1. In particular, the tank 3 open from above is, in the manner of a hopper, defined by a so-called front transverse wall 18, a so-called rear transverse wall 19 and two so-called lateral lateral walls 20. The leading edge of the smoothing table 4 extends to the base of the rear wall 19 of the tank 3 and the unloading opening 7 of the tank 3 is a closable opening.
Généralement, la table 4 de lissage, qui peut être formée par une simple tôle fixée au réservoir, en particulier à la paroi 19 arrière du réservoir au niveau de son bord 5 d'attaque présente une largeur comprise entre 0,60 à 1 ,20 m et une longueur comprise entre 30-40 cm pour former une surface d'appui suffisamment importante. Generally, the smoothing table 4, which can be formed by a simple sheet metal attached to the tank, in particular to the rear wall 19 of the tank at its leading edge, has a width of between 0.60 and 1.20. m and a length of between 30-40 cm to form a sufficiently large bearing surface.
Dans l'exemple représenté, le réservoir 3 est compartimenté par des cloisons 21 s'étendant parallèlement à l'axe longitudinal de l'engin 1 pris suivant la direction de déplacement de l'engin. Les moyens 22 d'obturation de l'ouverture 7 de déchargement comprennent une série de trappes 221 disposées côte à côte dans le sens de la largeur de l'engin. Lesdites trappes 221 sont montées mobiles entre une position fermée de l'ouverture 7 de déchargement dans laquelle lesdites trappes s'étendent au moins partiellement à l'intérieur du réservoir 3 et sont séparées l'une de l'autre par une cloison 21 , et une position ouverte de l'ouverture 7 de déchargement dans laquelle lesdites trappes 221 font au moins partiellement saillie dudit réservoir 3. Ces trappes 221 sont des trappes à profil courbe, à concavité tournée vers le fond du réservoir en position fermée. Au moins l'une des trappes est apte à se déplacer entre la position fermée et la position ouverte, indépendamment des autres trappes 221 . In the example shown, the tank 3 is partitioned by partitions 21 extending parallel to the longitudinal axis of the machine 1 taken in the direction of movement of the machine. The means 22 for closing the discharge opening 7 comprise a series of hatches 221 arranged side by side in the width direction of the machine. Said hatches 221 are movably mounted between a closed position of the unloading opening 7 in which said hatches extend at least partially inside the tank 3 and are separated from each other by a partition 21, and an open position of the unloading opening 7 in which said hatches 221 at least partially project from said tank 3. These hatches 221 are curved profile hatches, concavity turned towards the bottom of the tank in the closed position. At least one of the hatches is able to move between the closed position and the open position, independently of the other traps 221.
Dans l'exemple représenté, chaque trappe est associée à un vérin disposé à l'extérieur du réservoir et s'étendant entre le dessus de la table de lissage et la trappe. Ce vérin permet un déplacement à coulissement de la trappe associée, entre une position fermée et une position ouverte de l'ouverture de 9 In the example shown, each hatch is associated with a jack disposed outside the tank and extending between the top of the smoothing table and the hatch. This jack allows a sliding movement of the associated hatch, between a closed position and an open position of the opening of 9
déchargement du réservoir. Il est ainsi possible d'ouvrir certaines ou toutes les trappes, selon la largeur de travail souhaitée. unloading the tank. It is possible to open some or all traps, depending on the desired working width.
Pour varier le degré d'ouverture des trappes, et par suite le débit de distribution, l'engin peut être équipé d'une butée 23 de fin de course des trappes 221 en position ouverte. Cette butée 23 de fin de course est réglable en position. To vary the degree of opening of the hatches, and consequently the delivery rate, the machine can be equipped with a stop 23 end of the hatches 221 in the open position. This end stop 23 is adjustable in position.
Dans l'exemple représenté, la butée 23 de fin de course est formée par une tringle disposée à l'extérieur du réservoir et positionnable, en position active, sur la trajectoire suivie par les trappes 221 lors du passage de la position fermée à la position ouverte des trappes 221 . Cette tringle, qui s'étend le long de la largeur de l'engin, est ainsi logée à chacune de ses extrémités dans un flasque s'étendant en saillie du dessus de la table de lissage. Ces flasques s'étendent en regard l'un de l'autre et sont munis chacun d'une encoche équipée de crans de positionnement de l'extrémité de la tringle, pour un maintien de la tringle en position active, c'est-à-dire sur la trajectoire suivie par les trappes, ou en position inactive, c'est-à-dire en dehors de la trajectoire suivie par les trappes. In the example shown, the end stop 23 is formed by a rod disposed outside the tank and positionable, in the active position, on the trajectory followed by the hatches 221 when passing from the closed position to the position open hatches 221. This rod, which extends along the width of the machine, is thus housed at each of its ends in a flange projecting from the top of the smoothing table. These flanges extend facing one another and are each provided with a notch equipped with positioning notches of the end of the rod, for maintaining the rod in the active position, that is to say say on the trajectory followed by the traps, or in inactive position, that is to say outside the trajectory followed by the traps.
Pour parfaire cette possibilité de réglage de la largeur du lit, le réservoir 3 comprend deux volets 24 de réglage de la largeur du lit de matériaux en vrac à déposer. Chaque volet 24 s'étendant au-dessous des moyens 22 d'obturation de l'ouverture 7 de déchargement en position fermée de ladite ouverture 7 de déchargement. Chaque volet 24 est, au niveau de son bord dit supérieur, couplé à une paroi 20 latérale du réservoir 3 par une liaison pivot d'axe de pivotement parallèle au plan de la table 4 de lissage pour le passage dudit volet 24 d'une position en applique contre ladite paroi 20 latérale à une position écartée de ladite paroi 20 latérale. Le réglage en position de chaque volet s'opère ici manuellement à l'aide d'un levier pivotant extérieur au réservoir et en prise avec l'axe pivot du volet. Ce levier pivotant est apte à occuper plusieurs positions angulaires en fonction de la position souhaitée 10 To complete this possibility of adjusting the width of the bed, the tank 3 comprises two flaps 24 for adjusting the width of the bed of bulk material to be deposited. Each flap 24 extending below the means 22 for closing the opening 7 unloading in the closed position of said opening 7 unloading. Each flap 24 is, at its upper edge, coupled to a side wall 20 of the reservoir 3 by a fulcrum axis pivot connection parallel to the plane of the smoothing table 4 for the passage of said flap 24 of a position applied against said side wall at a position spaced from said side wall. The adjustment in position of each flap operates here manually using a pivoting lever outside the tank and engaged with the pivot axis of the flap. This pivoting lever is able to occupy several angular positions depending on the desired position 10
pour le volet. for the shutter.
Le réservoir 3 ainsi réalisé et la table 4 de lissage forment un ensemble monté sur le châssis 2. Le châssis 2 comprend donc une structure support du réservoir 3 et de la table 4 de lissage. Cette structure support entoure au moins partiellement les moyens moteurs d'entraînement des roues 8, par l'intermédiaire desquelles le châssis 2 repose au sol. Le châssis 2 pré-équipé du réservoir 3 et de la table 4 de lissage est donc, avec le réservoir 3 et la table 4 de lissage, monté à basculement autour de l'axe XX' de rotation des roues 8 par l'intermédiaire desquels il repose au sol, pour le passage dudit engin d'une configuration dite de travail dans laquelle la table 4 de lissage est en contact d'appui avec le sol à une configuration dite de transport dans laquelle la table 4 de lissage est écartée du sol. La configuration transport est illustrée à la figure 8. The reservoir 3 thus produced and the smoothing table 4 form an assembly mounted on the frame 2. The frame 2 thus comprises a support structure of the reservoir 3 and the smoothing table 4. This support structure at least partially surrounds the motor drive means of the wheels 8, through which the chassis 2 rests on the ground. The chassis 2 pre-equipped with the reservoir 3 and the smoothing table 4 is therefore, with the reservoir 3 and the smoothing table 4, mounted to tilt about the axis XX 'of rotation of the wheels 8 through which it rests on the ground, for the passage of said machine of a so-called working configuration in which the smoothing table 4 is in bearing contact with the ground to a so-called transport configuration in which the smoothing table 4 is removed from the ground . The transport configuration is shown in Figure 8.
Dans la configuration travail, l'engin peut présenter une position conforme à la figure 7, avec la table 4 de lissage en appui sur la surface déjà revêtue, ce revêtement n'étant pas représenté à la figure 7. In the work configuration, the machine may have a position according to FIG. 7, with the smoothing table 4 resting on the already coated surface, this coating not being represented in FIG. 7.
Pour permettre la commande en basculement, par le conducteur de l'engin 1 , l'engin 1 est équipé d'un guidon 15 en U sur lequel le conducteur peut prendre appui pour commander le basculement du châssis, notamment pour le passage en configuration de transport de l'engin. Généralement, sous l'effet du poids de la table de lissage et du réservoir, le réservoir tend à basculer naturellement en configuration travail lorsque le conducteur relâche son effort d'appui sur le guidon et a ramené le guidon dans une position dans laquelle le plan de la table s'étend horizontalement. Le réservoir 3 et la table 4 de lissage forment un ensemble monté de manière réglable en position sur le châssis 2. À cet effet, des moyens 91 , 92 de réglage sont prévus entre le réservoir 3 et le châssis 2. Ces moyens 91 , 92 de réglage sont prévus pour permettre un déplacement, de manière solidaire en déplacement, du réservoir 3 et de la table 4 de lissage. Ces moyens de réglage 11 To enable the tilting control by the driver of the machine 1, the machine 1 is equipped with a handlebar 15 U on which the driver can support to control the tilting of the chassis, especially for the passage in configuration of transport of the machine. Generally, under the effect of the weight of the smoothing table and the tank, the tank tends to tilt naturally in working configuration when the driver releases its support force on the handlebars and brought the handlebars to a position in which the plane of the table extends horizontally. The reservoir 3 and the smoothing table 4 form an assembly mounted adjustably in position on the frame 2. For this purpose, means 91, 92 of adjustment are provided between the reservoir 3 and the frame 2. These means 91, 92 adjustment are provided to allow displacement, in solidarity with displacement, of the reservoir 3 and the smoothing table 4. These adjustment means 11
comprennent deux actionneurs, en l'occurrence ici deux vérins 91 , 92 à actionnement indépendant, disposés chacun entre le châssis 2 et le réservoir 3. comprise two actuators, in this case two actuators 91, 92 with independent actuation, each arranged between the frame 2 and the reservoir 3.
Ainsi, chaque vérin 91 , 92, qui est un vérin hydraulique à double effet est couplé par sa tige 1 1 au châssis, en particulier à la partie du châssis entourant un demi-arbre de liaison d'une roue au bloc hydrostatique. Ainsi, l'un des vérins s'étend au niveau de l'un des demi-arbres et l'autre vérin au niveau de l'autre demi-arbre. Le corps de chaque vérin est quant à lui fixé par l'intermédiaire d'un bras 12 à la paroi 18 transversale dite avant du réservoir 3. Dans l'exemple représenté, l'un des bras 12 et la paroi 18 transversale avant du réservoir 3 sont couplés l'un à l'autre par une liaison 13 pivot d'axe transversal à l'axe XX' de rotation des roues 8 et parallèle au plan de la table de lissage. Ainsi, le bras 12 est équipé à son extrémité libre d'une platine circulaire qui vient se loger à rotation à l'intérieur d'un logement ménagé, de forme complémentaire, sur la face externe de la paroi 18 transversale avant du réservoir 3. L'autre des bras 12 et la paroi 18 transversale avant du réservoir sont couplés l'un à l'autre par une liaison 14 à pivotement et à coulissement, le coulissement étant apte à s'opérer suivant une direction parallèle au bord 5 d'attaque de la table 4 de lissage. À cet effet, la paroi 18 transversale avant du réservoir 3 est équipée de deux rails parallèles formant glissière disposés dans le sens de la largeur de l'engin, et le bras est équipé d'une platine circulaire venant s'insérer entre les rails parallèles de cette glissière. Thus, each cylinder 91, 92, which is a double-acting hydraulic cylinder is coupled by its rod 1 1 to the frame, in particular to the portion of the frame surrounding a half-shaft connecting a wheel to the hydrostatic block. Thus, one of the cylinders extends at one of the half-shafts and the other cylinder at the other half-shaft. The body of each jack is fixed by means of an arm 12 to the so-called front transverse wall 18 of the tank 3. In the example shown, one of the arms 12 and the front transverse wall 18 of the tank 3 are coupled to each other by a pivot link 13 axis transverse to the axis XX 'of rotation of the wheels 8 and parallel to the plane of the smoothing table. Thus, the arm 12 is equipped at its free end with a circular plate which is rotatably housed inside a housing of complementary shape on the external face of the front transverse wall of the tank 3. The other of the arms 12 and the front transverse wall 18 of the reservoir are coupled to each other by a link 14 pivoting and sliding, the sliding being able to operate in a direction parallel to the edge 5 of Smoothing Table 4 attack. For this purpose, the front transverse wall 18 of the tank 3 is equipped with two parallel rails forming a slideway arranged in the direction of the width of the machine, and the arm is equipped with a circular plate which fits between the parallel rails. of this slide.
Grâce à ce montage dans la position représentée à la figure 7 dans laquelle les roues 8 du châssis 2 roulant reposent sur un sol 25 plan horizontal et la table 4 de lissage s'étend parallèlement au sol, à écartement du sol, l'entraînement en déplacement des corps 10 de vérin dans le sens d'un allongement des vérins entraîne une élévation de la table 4 de lissage et du réservoir 3 associé, pour permettre un réglage en hauteur, fonction de 12 With this assembly in the position shown in Figure 7 in which the wheels 8 of the chassis 2 rolling rest on a horizontal plane 25 and the smoothing table 4 extends parallel to the ground, spaced from the ground, the drive displacement of the cylinder body 10 in the direction of an elongation of the cylinders causes an elevation of the smoothing table 4 and associated reservoir 3, to allow adjustment in height, depending on 12
l'épaisseur de la couche de matériaux en vrac à déposer. Ainsi, les vérins 91 , 92 permettent un déplacement en monte ou baisse dudit ensemble 3, 4 dans le sens d'un rapprochement ou d'un écartement du sol. Ces vérins 91 , 92, qui peuvent être actionnés indépendamment l'un de l'autre, permettent encore de faire varier l'angle a formé entre le plan de la table 4 de lissage et l'axe XX' de rotation des roues. Ainsi, dans la position représentée à la figure 7 ou à la figure 4, l'allongement du vérin 92 entraîne un déplacement à pivotement de la table autour de l'axe YY' horizontal orthogonal à l'axe XX' de rotation des roues, cet axe YY' correspondant à l'axe pivot de la liaison 14 pivot du bras 12 du vérin 91 avec le réservoir 3. Ce déplacement à pivotement entraîne une inclinaison de la table 4 de lissage dans le sens de la largeur de l'engin, c'est- à-dire avec une pente de la table s'étendant depuis un point haut formé par l'un des bords longitudinaux de la table 4 de lissage et un point bas formé par l'autre bord longitudinal de la table 4 de lissage. Ce réglage de l'inclinaison de la table 4 de lissage permet ainsi à l'engin de gérer une situation conforme à la figure 5, dans laquelle la roue 8 située côté du vérin 92 repose sur la surface à revêtir, alors que la roue 8 située côté du vérin 91 repose sur une surface déjà revêtue donc située à un niveau supérieur. Il en résulte la formation d'une marche entre lesdites surfaces. En dépit de la présence de cette marche, on constate que le plan de la table 4 de lissage demeure horizontal, en raison de l'angle a aigu formé entre l'axe de rotation des roues et le plan d'appui de la table. the thickness of the bulk material layer to be deposited. Thus, the cylinders 91, 92 allow a movement upward or downward of said assembly 3, 4 in the direction of a rapprochement or a separation of the ground. These cylinders 91, 92, which can be actuated independently of one another, further allow to vary the angle formed between the plane of the smoothing table 4 and the axis XX 'of rotation of the wheels. Thus, in the position shown in FIG. 7 or in FIG. 4, the elongation of the jack 92 causes the table to pivot about the horizontal axis YY 'orthogonal to the axis XX' of rotation of the wheels, this axis YY 'corresponding to the pivot axis of the link 14 pivot arm 12 of the cylinder 91 with the reservoir 3. This pivotal movement causes an inclination of the smoothing table 4 in the direction of the width of the machine, that is to say with a slope of the table extending from a high point formed by one of the longitudinal edges of the smoothing table 4 and a low point formed by the other longitudinal edge of the table 4 of smoothing. This adjustment of the inclination of the smoothing table 4 thus enables the machine to manage a situation according to FIG. 5, in which the wheel 8 located on the side of the jack 92 rests on the surface to be coated, whereas the wheel 8 situated on the side of the jack 91 rests on an already coated surface, thus situated at a higher level. This results in the formation of a step between said surfaces. Despite the presence of this step, it can be seen that the plane of the smoothing table 4 remains horizontal, because of the acute angle α formed between the axis of rotation of the wheels and the support plane of the table.
Bien évidemment, dans le cas d'une situation où c'est la roue située du côté du vérin 91 qui doit reposer sur la surface à revêtir, on procède à une extension de la longueur du vérin 91 . Il est donc possible, selon les vérins actionnés, d'obtenir un angle a aigu d'un côté ou de l'autre de l'engin. Il est ainsi possible de maintenir l'horizontalité de la table 4 de lissage en absence d'une planéité du sol. Obviously, in the case of a situation where it is the wheel located on the side of the cylinder 91 which must rest on the surface to be coated, it proceeds to an extension of the length of the cylinder 91. It is therefore possible, depending on the jacks actuated, to obtain an acute angle to one side or the other of the machine. It is thus possible to maintain the horizontality of the smoothing table 4 in the absence of ground flatness.
Dans l'exemple représenté, les branches du U du guidon 15 couplent l'âme 17 13 In the example shown, the branches of the U of the handlebar 15 couple the core 17 13
du U formant poignée aux vérins 91 , 92. L'une des branches 16 du U est couplée à l'un des vérins 92 de manière déplaçable à coulissement le long dudit vérin 92, pour éviter toute déformation du guidon au cours de l'allongement ou de la rétractation des vérins. Pour permettre la dépose de matériaux en vrac au sol sous forme d'un lit à l'aide d'un engin tel que décrit ci-dessus, on procède donc comme suit : les trappes 221 étant en position fermée de l'ouverture de déchargement du réservoir 3, on remplit par le dessus ledit réservoir 3. Le contenu de la benne d'un camion peut par exemple être déversé directement par le dessus dans ledit réservoir 3. Une fois le réservoir 3 rempli, l'engin, en configuration transport, est amené par son conducteur sur l'emplacement de la surface à revêtir. Le conducteur de l'engin utilise une cale, ou prépare dans la zone de départ de la surface à revêtir, une base d'épaisseur correspondant à l'épaisseur de la couche devant être déposée. Le conducteur de l'engin procède aux réglages en hauteur et en inclinaison de la table et du réservoir associé en agissant sur les tiges des vérins, commandées en rentrée ou en sortie à partir d'organes de commande placés au niveau du guidon de l'engin, de sorte que la table 4 de lissage repose, après réglage, à l'horizontale sur la cale ou la base préparée, tandis que les roues 8 de l'engin reposent sur la surface à revêtir, que cette surface soit plane ou non. of the U forming a handle to the cylinders 91, 92. One of the legs 16 of the U is coupled to one of the cylinders 92 in a displaceably sliding manner along said cylinder 92, to avoid any deformation of the handlebar during the elongation or the retraction of the cylinders. To allow the removal of bulk materials in the form of a bed bed using a machine as described above, it is therefore as follows: the hatches 221 being in the closed position of the unloading opening of the tank 3, it is filled from above said tank 3. The contents of the bucket of a truck can for example be poured directly from above into said tank 3. Once the tank 3 filled, the machine, in transport configuration , is brought by its driver on the location of the surface to be coated. The driver of the machine uses a shim, or prepares in the starting zone of the surface to be coated, a base of thickness corresponding to the thickness of the layer to be deposited. The driver of the machine makes the adjustments in height and inclination of the table and the associated tank by acting on the rods of the cylinders, controlled in or out from control members placed at the handlebar of the gear, so that the smoothing table 4 rests, after adjustment, horizontally on the wedge or the prepared base, while the wheels 8 of the machine rest on the surface to be coated, whether this surface is plane or not .
L'engin est alors en configuration travail. Les trappes 21 1 sont ouvertes, pour permettre une vidange du réservoir de l'engin et la dépose des matériaux en vrac contenus à l'intérieur de l'engin sur le sol. The machine is then in working configuration. The hatches 21 1 are open, to allow emptying of the tank of the machine and the removal of loose materials contained inside the machine on the ground.
L'engin se déplace avec le guidon formant l'avant de l'engin, et la table 4 de lissage l'arrière de l'engin comme l'illustre la flèche D à la figure 7. L'ouverture de déchargement du réservoir est disposée en avant de la table 4 de lissage et les roues en avant de l'ouverture de déchargement du réservoir. La cale ou la base est donc en arrière de l'engin. The machine moves with the handlebar forming the front of the machine, and the table 4 smoothing the rear of the machine as illustrated by the arrow D in Figure 7. The unloading opening of the tank is disposed forward of the smoothing table 4 and the wheels in front of the unloading opening of the tank. The hold or base is behind the craft.
L'engin est piloté en direction par le conducteur de l'engin agissant sur le 14 The machine is steered in the direction by the driver of the machine acting on the 14
guidon. Les roues circulent d'abord sur la surface à revêtir. Les matériaux en vrac tombent par gravité sur le sol, c'est-à-dire sur la surface à revêtir. Lors de l'avance de l'engin, ces matériaux en vrac déposés sont lissés ou nivelés par la table 4 de lissage qui repose constamment en appui sur la surface venant d'être revêtue. handlebar. The wheels move first on the surface to be coated. Loose materials fall by gravity onto the floor, that is to say on the surface to be coated. During the advance of the machine, these bulk materials deposited are smoothed or leveled by the smoothing table 4 which is constantly resting on the surface just coated.
Dans un cas d'application particulier, à savoir le gravillonnage d'une surface, l'engin peut également être utilisé avec un sens de déplacement opposé, c'est- à-dire avec la table de lissage formant l'avant de l'engin. Dans ce cas, l'ouverture des trappes est bridée à une valeur donnée et l'engin est utilisé avec cette direction de déplacement pour effectuer un tel gravillonnage. In a particular application case, namely the graveling of a surface, the machine can also be used with an opposite direction of movement, that is to say with the smoothing table forming the front of the machine. In this case, the opening of the hatches is clamped to a given value and the machine is used with this direction of movement to perform such a gravel.
