Abstract
Description
La présente invention est relative à un dispositif de suspension pour une rampe de pulvérisation agricole. The present invention relates to a suspension device for an agricultural sprayer boom.
On sait que,en raison des sollicitations verticales et horizontales d'une rampe de pulvérisation agricole, dues au déplacement sur un terrain irrégulier, il est nécessaire d'amortir les mouvements de la rampe, et ce d'autant plus que, suivant une tendance qui va en s'amplifiant, les rampes ont des longueurs de plus en plus importantes. We know that, due to the vertical and horizontal stresses of an agricultural sprayer boom, due to movement on uneven ground, it is necessary to dampen the movements of the boom, all the more so as, following a trend which is increasing, the ramps are becoming longer and longer.
Dans un agencement connu de rampe , la rampe comporte un élément central, ou balançoire, quiet réglable en hauteur à l'aide d'un vérin hydraulique disposé entre un bâti fixe appartenant à l'engin de pulvérisation et un châssis auquel l'élément central est suspendu par gravité en au moins un point. Pour tenter d'amortir les sollicitations brusques auxquelles la rampe est soumise, il est connu de mettre l'une des chambres du vérin de réglage en hauteur en communication avec un accumulateur de pression, en général un accumulateur à azote.Mais cet agencement ne donne pas satisfaction car, lorsqu'un mouvement- brusque vertical ou horizontal est appliqué à la rampe, ce mouvement engendre des efforts entre le châssis supportant directement la rampe et le bâti arrière, ce qui empêche le vérin et l'accumulateur de remplir de manière satisfaisante leur rôle d'amortissement. In a known boom arrangement, the boom comprises a central element, or swing, quiet adjustable in height using a hydraulic cylinder arranged between a fixed frame belonging to the spraying machine and a frame to which the central element is suspended by gravity at at least one point. To try to dampen the sudden stresses to which the ramp is subjected, it is known to put one of the chambers of the height adjustment cylinder in communication with a pressure accumulator, generally a nitrogen accumulator. But this arrangement does not give not satisfaction because, when a sudden vertical or horizontal movement is applied to the ramp, this movement generates forces between the chassis directly supporting the ramp and the rear frame, which prevents the jack and the accumulator from satisfactorily filling their depreciation role.
L'invention a pour but de remédier à cet inconvénient en fournissant un dispositif de suspension qui permette d'amortir efficacement et simplement les sollicitations ci-dessus. The object of the invention is to remedy this drawback by providing a suspension device which allows the above stresses to be absorbed efficiently and simply.
A cet effet, le dispositif selon l'invention est caractérisé par le fait qu'il comporte, en série entre l'élé- ment central de la rampe et le châssis supportant la rampe par l'élément central, au moins un amortisseur pneumatique qui est constitué par un vérin dont l'une des chambres est reliée à un accumulateur de pression, notamment un accumulateur à azote. To this end, the device according to the invention is characterized in that it comprises, in series between the central element of the ramp and the chassis supporting the ramp by the central element, at least one pneumatic damper which consists of a jack, one of the chambers of which is connected to a pressure accumulator, in particular a nitrogen accumulator.
Suivant un premier mode de réalisation, l'élément central de la rampe est guidé transversalement par rapport au châssis et il est suspendu à celui-ci en son centre par un amortisseur pneumatique unique. According to a first embodiment, the central element of the ramp is guided transversely with respect to the chassis and it is suspended from the latter in its center by a single pneumatic damper.
Suivant un second mode de réalisation, l'élément central de la rampe est suspendu au châssis par deux biellettes divergentes, et en général d'égale longueur, un amortisseur pneumatique étant incorporé en série dans chaque billette. According to a second embodiment, the central element of the ramp is suspended from the chassis by two divergent links, and generally of equal length, a pneumatic damper being incorporated in series in each billet.
En général, le châssis est un châssis intermédiaire qui est lui-même supporté de manière réglable en hauteur par un bâti fixe, le réglage en hauteur étant obtenu à l'aide d'un vérin hydraulique qui est disposé en série entre le châs- sis intermédiaire et le bâti fixe. In general, the chassis is an intermediate chassis which is itself supported in an adjustable manner in height by a fixed frame, the height adjustment being obtained by means of a hydraulic cylinder which is arranged in series between the chassis. intermediate and fixed frame.
On comprendra bien l'invention à la lecture du complément de description qui va suivre et en référence aux dessins annexés qui font partie de la description et dans lesquels

Fig. 2 est une coupe verticale longitudinale suivant la ligne II-II de la Fig. 1 ; et
Figs. 3 et 4 sont des vues analogues respectivement aux
Figs. 1 et 2 et relatives à un second mode de réalisation de l'invention.The invention will be clearly understood on reading the additional description which follows and with reference to the appended drawings which form part of the description and in which
Fig. 1 is a schematic rear elevation view showing part of an agricultural sprayer boom mounted on a machine and equipped with a suspension device according to a first embodiment of the invention
Fig. 2 is a longitudinal vertical section along the line II-II of FIG. 1; and
Figs. 3 and 4 are views similar to respectively
Figs. 1 and 2 and relating to a second embodiment of the invention.
On décrira tout d'abord , en référence aux Figs. 1 à 4, les éléments communs aux deux modes de réalisation de l'lnven- tion. We will first describe, with reference to Figs. 1 to 4, the elements common to the two embodiments of the invention.
La rampe de pulvérisation 1 est constituée par un élément central 2, ou balançoire, et, de chaque côté de l'élément central 2, par un élément latéral 3, en général en au moins deux troncons articulés, chaque élément 3 étant lui-même articulé sur l'élément central 2 autour d'une articulation 4 généralement verticale. L'élément central 2 est suspendu par gravite a un châssis vertical 5 en au moins un point. A son tour, le châssis 5 est supporté par un châssis principal ou bâti fixe 6 qui est solidaire du châssis 7 de l'engin de pulvérisation.Le châssis 5 est réglable en hauteur sur le bâti 6 par l'intermédiaire d'un vérin hydraulique 8 qui est activé par la centrale hydraulique de l'engin de pulvérisation et dont un élemerrt 9, par exempie le corps, est relié au châssis 7 de l'engin tandis que son autre élément 10, par exemple sa tige, est relié au châssis 5. The spraying boom 1 is constituted by a central element 2, or swing, and, on each side of the central element 2, by a lateral element 3, generally in at least two articulated sections, each element 3 being itself articulated on the central element 2 around a generally vertical articulation 4. The central element 2 is suspended by gravity from a vertical frame 5 at at least one point. In turn, the frame 5 is supported by a main frame or fixed frame 6 which is integral with the frame 7 of the spraying machine. The frame 5 is adjustable in height on the frame 6 by means of a hydraulic cylinder 8 which is activated by the hydraulic unit of the spraying machine and an element 9 of which, for example the body, is connected to the chassis 7 of the machine while its other element 10, for example its rod, is connected to the chassis 5.
Conformément à l'invention, la rampe 1 est suspendue par gravité au châssis 5, en au moins un point, par un dispositif de suspension qui comporte, en série entre l'élément central 2 de la rampe et le châssis 5, au moins un amortisseur pneumatique 11 constitué par un vérin dont l'une des chambres est reliée à un accumulateur de pression 12, par exemple un accumulateur à azote. According to the invention, the ramp 1 is suspended by gravity from the chassis 5, at at least one point, by a suspension device which comprises, in series between the central element 2 of the ramp and the chassis 5, at least one pneumatic shock absorber 11 constituted by a jack one of the chambers of which is connected to a pressure accumulator 12, for example a nitrogen accumulator.
Dans le mode de réalisation des Figs. 1 et 2, l'élément central 2 de la rampe est guidé transversalement par rapport au châssis 5 et il est suspendu à celui-ci en son centre par un-amortisseur il unique dont le corps 13 est relié à l'élément central 2 tandis que sa tige 14 est reliée au châssis 5. In the embodiment of Figs. 1 and 2, the central element 2 of the ramp is guided transversely with respect to the chassis 5 and it is suspended from the latter in its center by a single shock absorber the body 13 of which is connected to the central element 2 while that its rod 14 is connected to the chassis 5.
L'amortisseur 11 est vertical et l'accumulateur 12 est en communication avec la chambre côté tige du vérin. The damper 11 is vertical and the accumulator 12 is in communication with the chamber on the rod side of the jack.
Dans le mode de réalisation des Figs. 3 et 4, l'élément central 2 de la rampe est cette fois suspendu au châssis 5 par deux biellettes 15, en général divergentes vers le bas et d'égale longueur, un amortisseur pneumatique il, avec son accumulateur associé 12, étant incorporé en série dans chaque biellette. Dans la pratique, comme on peut le voir sur les
Figs. 3 et 4, chaque amortisseur Il constitue en fait luimême la biellette correspondante 15, son corps 13 étant relié à l'élément central 2 et sa tige 14 étant reliée au châssis 5 qui, dans ce mode de réalisation, comporte une traverse horizontale 16 aux extrémités de laquelle sont accrochés les deux amortisseurs 11.In the embodiment of Figs. 3 and 4, the central element 2 of the ramp is this time suspended from the chassis 5 by two rods 15, generally divergent downwards and of equal length, a pneumatic damper there, with its associated accumulator 12, being incorporated in series in each link. In practice, as can be seen on the
Figs. 3 and 4, each damper It in fact constitutes itself the corresponding link 15, its body 13 being connected to the central element 2 and its rod 14 being connected to the chassis 5 which, in this embodiment, comprises a horizontal crosspiece 16 aux ends of which the two shock absorbers 11 are hung.
En fonctionnement, les sollicitations auxquelles est soumise la rampe de la part du châssis 7 de l'engin de pulvéirisation sont efficacement et directement absorbées par le ou les accumulateurs 11 du fait que l'amortissement s'effectue immédiatement au niveau du montage de l'élément central 2 de la rampe, sans que les efforts qui peuvent exister entre le châssis 5 et le bâti fixe 6 interviennent dans cet amortissement. In operation, the stresses to which the ramp is subjected on the part of the chassis 7 of the sprayer are effectively and directly absorbed by the accumulator or accumulators 11 because the damping takes place immediately at the mounting of the central element 2 of the ramp, without the forces which may exist between the chassis 5 and the fixed frame 6 intervening in this damping.
Bien entendu, l'invention n'est pas limitée-aux modes de réalisation qui ont été décrits ; on pourrait au contraire concevoir diverses variantes sans sortir pour autant de son cadre;c'est ainsi que, dans le cas d'un vérin amortisseur 11 unique (Figs 1 et 2), celui-ci peut être horizontal et associé à un mécanisme de renvoi,notamment à câble. Of course, the invention is not limited to the embodiments which have been described; on the contrary, it would be possible to conceive of various variants without thereby departing from its framework; this is how, in the case of a single damping cylinder 11 (FIGS. 1 and 2), it can be horizontal and associated with a reference, in particular to cable.
