Abstract
Description
La présente invention a pour objet un dispositif de braquage de roues surThe present invention relates to a device for steering wheels on
une machine à ramasser -es fruits tombés au sol en vue d'une transformation aiimentaire, destiné à permettre au ramasseur de ladite machine de pouvoir travailser en tournant autour du pied de l'arbre. Un dispositif de braquage connu consiste à orienter les a machine for collecting fruit fallen to the ground for food processing, intended to allow the collector of said machine to be able to work by turning around the base of the tree. A known turning device consists in orienting the
quatre roues directrices d'une machine à ramasser les fruits. four-wheel steering of a fruit picking machine.
Toutefois, l'angle de braquage, résultant de l'orientation des deux roues intérieures, ne permet pas d'obtenir un rayon de braquage suffisamment court pour que, son ramasseur situé à l'avant des quatre roues évolue en However, the steering angle, resulting from the orientation of the two inner wheels, does not make it possible to obtain a turning radius short enough for its pickup located at the front of the four wheels to evolve.
tournant au pied de l'arbre.turning at the foot of the tree.
Un autre dispositif de braquage comporte à l'arrière de la machine à ramasser les fruits une roue directrice centrale qui forme avec l'axe des deux roues avant, non -orientables, Another turning device comprises at the rear of the fruit picking machine a central steering wheel which forms with the axis of the two front wheels, which are not steerable,
un petit rayon de braquage.a small turning radius.
Toutefois ce dispositif de braquage sur cette machine ne permet pas au ramasseur situé en avant des roues de travailler la zone de fruits tombés en tournant à proximité du pied de l'arbre. De plus la disposition du ramasseur par rapport aux roues de la machine pose également le problème de suivi du sol. En effet, les roues évoluants sur du terrain agricole engendrent au ramasseur des différences de niveau, soit une hauteur variable entre ledit ramasseur par rapport However, this turning device on this machine does not allow the picker located in front of the wheels to work the area of fallen fruit while turning near the base of the tree. In addition, the arrangement of the pickup relative to the wheels of the machine also poses the problem of following the ground. Indeed, the wheels moving on agricultural land generate differences in level for the collector, that is to say a variable height between said collector with respect to
au sol.on the ground.
Un dispositif également connu sur une machine à ramasser les fruits est constitué en côté d'une roue avant, directrice et, à l'arrière, de deux roues non-orientables. Pour parcourir le tour d'un arbre avec ce dispositif, le centre du rayon de braquage passant par l'axe des deux roues arrières, doit être confondu avec le centre du diamètre représentant le A device also known on a fruit picking machine consists of a front steering wheel and, at the rear, two non-steerable wheels. To travel around a tree with this device, the center of the turning radius passing through the axis of the two rear wheels must be confused with the center of the diameter representing the
pied de l'arbre.foot of the tree.
Toutefois, le ramasseur est placé transversalement à la machine, entre la roue avant et les deux roues arrières et, However, the pickup is placed transversely to the machine, between the front wheel and the two rear wheels and,
travaille de biais ne pouvant utiliser toute sa longueur. working at an angle that cannot use its entire length.
Un autre dispositif braque les deux roues d'une mach'ne à Another device steers two wheels of a machine
ramasser les fruits, tirée par un tracteur. picking up the fruit, pulled by a tractor.
Toutefois ce dispositif n'est pas destiné à permettre au ramasseur de cette machine, d'approcher les arbres, mais à tourner en bout des andains de fruits. La présente invention a pour but de remédier aux inconvénients des dispositifs connus sur les machines à ramasser ies fruits en proposant, un dispositif de braquage destiné à permettre au ramasseur de pouvoir travailler à la fois, de front sur toute la longueur, en tournant autour du pied de l'arbre et en se maintenant d'une hauteur constante However, this device is not intended to allow the picker of this machine to approach the trees, but to turn the end of the fruit swaths. The object of the present invention is to remedy the drawbacks of the known devices on fruit picking machines by proposing a turning device intended to allow the picker to be able to work simultaneously, head-on over the entire length, by turning around the foot of the tree and keeping a constant height
par rapport au sol.relative to the ground.
Pour se faire, le dispositif de braquage comporte par rapport à la machine, une roue avant gauche, non orientable et, deux roues arrières, directrices dont celle de gauche est à la fois plus en arrière que celle de droite et, plus à To do this, the turning device comprises with respect to the machine, a front left wheel, not steerable and, two rear wheels, steered, the left one of which is both further back than the right one and, more
gauche que la roue avant de manière à accroitre La stabilité. left as the front wheel so as to increase stability.
Ce dispositif permet de disposer en côté de la roue avant un ramasseur de sorte que de profil le centre du diamètre dudit ramasseur et le centre du diamètre de la roue avant se This device makes it possible to have a pick-up side of the front wheel so that in profile the center of the diameter of said pick-up and the center of the diameter of the front wheel are
trouvent alignés sur un même axe perpendiculaire au sol. are aligned on the same axis perpendicular to the ground.
Selon une autre caractéristique de ce dispositif de braquage, lorsque le ramasseur tourne autour du pied de l'arbre, le rayon décrit par la roue avant est confondu au rayon de la roue arrière droite, évitant ainsi de trop According to another characteristic of this turning device, when the pickup rotates around the base of the shaft, the radius described by the front wheel is coincident with the radius of the right rear wheel, thus avoiding too much
marquer le terrain.mark the field.
Selon un mode préférentiel le dispositif de braquage vu de dessus permet au ramasseur de pouvoir travailler en According to a preferred mode, the turning device seen from above allows the collector to be able to work in
tournant au pied de l'arbre dans le sens horaire. turning at the foot of the tree clockwise.
Symétriquement la présente invention tient compte d'un Symmetrically, the present invention allows for a
dispositif tournant dans le sens anti-horaire. device rotating counterclockwise.
Les dessins annexés illustrent l'invention: La figure 1 représente une vue de dessus du dispositif de braquage; La figure 2 représente de profil, le dispost-if selon l'invention. En référence à ces dessins, le dispositif comporte par rapport à la machine, une roue avant gauche [-} non S orientable et deux roues directrices dont une roue arrière gauche (2), articulée par un pivot (8), située plus en arrière que la roue arriere droite (3), articuilée par un The accompanying drawings illustrate the invention: Figure 1 shows a top view of the turning device; Figure 2 shows in profile, the dispost-if according to the invention. With reference to these drawings, the device comprises with respect to the machine, a left front wheel [-} non S steerable and two steered wheels including a left rear wheel (2), articulated by a pivot (8), located further back that the right rear wheel (3), articulated by a
pivot (9) et, plus à gauche que la roue avant (. i- pivot (9) and, more to the left than the front wheel (. i-
comporte également un ramasseur (4) situé en côté de ia roue avant, de telle sorte que le centre du diamètre dudit ramasseur (4) et le centre de la roue avant (1), se trouvent alignés sur un même axe perpendiculaire au sol. L'orientation des roues directrices se réalise par la commande d'un vérin also includes a pickup (4) located next to the front wheel, so that the center of the diameter of said pickup (4) and the center of the front wheel (1) are aligned on the same axis perpendicular to the ground. The steering wheels are oriented by controlling a cylinder

Le dispositif selon l'invention est particulièrement destiné à permettre au ramasseur de machines à ramasser les fruits de pouvoir travailler en tournant autour du pied de l'arbre. The device according to the invention is particularly intended to allow the picker of fruit picking machines to be able to work by turning around the base of the tree.
