Abstract
Description
Dispositif de disque anti-dévers pour pulvériseurs et notamment les pulvériseurs avec trains de disques disposés en x parfait. Anti-roll disc device for sprayers and in particular sprayers with disc trains arranged in perfect x.
La présente invention concerne un dispositif de disque anti-dévers pour pulvériseurs et notamment les pulvériseurs avec trains de disques disposés en X parfait. The present invention relates to an anti-roll disc device for sprayers and in particular sprayers with train of discs arranged in perfect X.
On sait que les pulvériseurs ont généralement tendance à se mettre légèrement en travers lors de travaux en dévers. En effet, les composantes d'efforts transversales s'exerçant sur les trains de disques sont théoriquement équilibrées de sorte que en devers, la composante transversale du poids du pulvériseur joue de façon non négligeable. A cette tendance de mise en travers du pulvériseur, seule s'oppose la composante longitudinale de réaction à la traction de l'appareil en travail. We know that sprayers generally tend to get slightly across when working on slopes. In fact, the components of transverse forces exerted on the train of discs are theoretically balanced so that in the tilted direction, the transverse component of the weight of the sprayer plays a significant role. To this tendency of crossing the sprayer, only the longitudinal component of reaction to traction of the apparatus in opposition is opposed.
L'invention vise à remédier à cet inconvénient en proposant un dispositif de disque anti-dévers pour pulvériseurs, notamment les pulvériseurs avec trains de disques disposés en X parfait, caractérisé en ce qu'il comporte un disque plan de grand diamètre, de l'ordre de grandeur de ceux des disques des trains aratoires ou légèrement supérieur, monté libre en rotation axiale en suspension élastique sur le châssis du pulvériseur, disposé en position sensiblement centrale et dans le plan médian longitudinal de ce dernier, en sorte de pénétrer le sol en roulement d'une profondeur sensiblement constante lors du travail, ladite suspension élastique autorisant un effacement vertical du disque devant un obstacle ou inégalité du sol mais résistant aux efforts transversaux de façon à maintenir le pulvériseur en ligne au cours du travail. The invention aims to remedy this drawback by proposing an anti-roll disc device for sprayers, in particular sprayers with disc trains arranged in perfect X, characterized in that it comprises a flat disc of large diameter, of the order of magnitude of those of the discs of the agricultural trains or slightly higher, mounted free in axial rotation in elastic suspension on the chassis of the sprayer, disposed in a substantially central position and in the longitudinal median plane of the latter, so as to penetrate the ground in rolling of a substantially constant depth during work, said elastic suspension allowing vertical erasure of the disc in front of an obstacle or unevenness of the ground but resistant to transverse forces so as to keep the sprayer in line during work.
Cette suspension élastique du disque est assurée avantageusement par deux lames-ressorts cintrées classiques disposées verticalement de chaque côté du disque et reliées toutes deux, à leur niveau haut, par exemple, par une bride de serrage .au châssis du pulvériseur et recevant à leur niveau inférieur l'axe de rotation du disque. This elastic suspension of the disc is advantageously provided by two conventional curved leaf springs arranged vertically on each side of the disc and both connected, at their high level, for example, by a clamping flange. To the chassis of the sprayer and receiving at their level lower the axis of rotation of the disc.
Selon une disposition avantageuse de l'invention convenant en particulier aux pulvériseurs en X parfait, le disque peut recevoir deux rasettes, droite et gauche, disposées très proches l'une de l'autre, le long de la surface du disque, et réglables en profondeur. Ces deux rasettes permettent de travailler la bande centrale de largeur 8 à lOcm, non remuée par les trains de disques avant. Le réglage en profondeur des rasettes, équivalent pour chacune d'elle, permet d'ajuster la répartition et le volume de terre remuée qui sera reprise par les deux trains de disques arrière afin d'obtenir une bonne finition de travail. According to an advantageous arrangement of the invention particularly suitable for sprayers in perfect X, the disc can receive two skimmers, right and left, arranged very close to each other, along the surface of the disc, and adjustable in depth. These two skimmers allow you to work the central band of width 8 to 10 cm, not disturbed by the front disc trains. The depth adjustment of the skimmers, equivalent for each of them, makes it possible to adjust the distribution and the volume of stirred earth which will be taken up by the two rear disc trains in order to obtain a good working finish.
L'invention est illustrée ci-après à l'aide d'un exemple de réalisation et en référence au dessin annexé sur lequel:
La figure 1 est une vue en perspective d'un dispositif de disque anti-dévers selon l'invention et
La figure 2 est une vue de dessus de ce dispositif.The invention is illustrated below with the aid of an exemplary embodiment and with reference to the appended drawing in which:
FIG. 1 is a perspective view of an anti-roll disc device according to the invention and
Figure 2 is a top view of this device.
Avec référence aux figures, le dispositif selon l'invention est essentiellement constitué d'un disque plan 1 monté libre en rotation axiale sur deux lames-ressort 3, disposées de chaque côté de son axe et symétriques l'une de l'autre par rapport au plan du disque. With reference to the figures, the device according to the invention essentially consists of a flat disc 1 mounted freely in axial rotation on two leaf springs 3, arranged on each side of its axis and symmetrical with respect to each other in terms of the disc.
Ces lames sont cintrées pour former un arrondi sur l'avant. Elles sont reliées rigidement au châssis par leur plat supérieur au moyen d'une bride de serrage classique non représentée appliquée sur une traverse du châssis, par exemple une traverse longitudinale médiane. Le montage est réalisé en sorte que le disque soit disposé sous le châssis du pulvériseur, en position centrale et avec son axe perpendiculaire au plan longitudinal médian de ce dernier. L'axe du disque est relié aux plats inférieurs des lames. Le diamètre du disque est équivalent à celui des disques des trains aratoires du pulvériseur et son axe sensiblement au niveau de ceux de ces derniers. These blades are curved to form a rounded front. They are rigidly connected to the chassis by their upper plate by means of a conventional clamp not shown applied to a cross member of the chassis, for example a median longitudinal cross member. The assembly is carried out so that the disc is placed under the chassis of the sprayer, in the central position and with its axis perpendicular to the longitudinal median plane of the latter. The axis of the disc is connected to the lower plates of the blades. The diameter of the disc is equivalent to that of the discs of the sprayer's agricultural trains and its axis substantially at the level of those of the latter.
Les lames-ressorts sont tordues à leur extrémité inférieure de façon à porter chacune au moyen d'une bride classique 4 une rasette 5 réglable en profondeur. Ces rasettes sont montées symétriques l'une de l'autre par rapport au plan du disque et disposées très proches de la surface de ce dernier. Cette disposition avec rasettes convient, comme déjà mentionné, aux pulvériseurs en X parfait. The leaf springs are twisted at their lower end so as to each carry by means of a conventional flange 4 a razor 5 adjustable in depth. These skimmers are mounted symmetrical to each other with respect to the plane of the disc and arranged very close to the surface of the latter. This arrangement with skimmers is suitable, as already mentioned, for perfect X sprayers.
Ainsi, en position de travail le disque s'enfonce dans le sol et le taille longitudinalement en roulant. Thus, in the working position the disc sinks into the ground and cuts it longitudinally while rolling.
Ce faisant, il maintient le pulvériseur en ligne au cours du travail et notamment en condition de dévers. Les rasettes réglées en profondeur remuent la bande avant non travaillée par les trains de disques avant. Cette bande ainsi travaillée est reprise par les trains de disques arrière pour une finition parfaite du sol travaillé. In doing so, it keeps the sprayer in line during work and in particular in a slope condition. The razors adjusted in depth move the front strip not worked by the front disc trains. This strip thus worked is taken up by the rear disc trains for a perfect finish of the worked floor.
L'arrondi des lames-ressorts en se déformant permet au disque de s'effacer sur les inégalités du sols, telles que pierres, racines, etc.... The roundness of the leaf springs when deformed allows the disc to fade over uneven ground, such as stones, roots, etc.
L'invention apporte ainsi un dispositif simple et fiable permettant de tenir en ligne les pulvériseurs et particulièrement adapté aux pulvériseurs en X parfait. The invention thus provides a simple and reliable device for keeping sprayers in line and particularly suitable for sprayers in perfect X.
