Abstract
Description
La présente invention a pour objet un dispositif destiné à éliminer les feuilles d'un flux d'air véhiculant lesdites feuilles. The present invention relates to a device intended to eliminate the sheets from an air flow conveying said sheets.
Il existe de nombreuses machines agricoles dans lesquelles il est nécessaire d'éliminer des feuilles qui sont déta chées, soit par des outils de coupe, dans le cas d'une écimeuse ou d'une effeuilleuse, soit par tout autre moyen, comme les dispositifs destinés à détacher les raisins dans une machine à vendanger. Pour réaliser cette élimination, il est usuel d'employer des dispositifs d'aspirction qui aspirent les feuilles et les rejettent. There are many agricultural machines in which it is necessary to remove leaves which are detached, either by cutting tools, in the case of a topper or leaf stripper, or by any other means, such as devices intended to detach the grapes in a harvesting machine. To achieve this elimination, it is usual to use suction devices which suck up the leaves and reject them.
Ce rejet, avec le courant d'air, pouvant présenter des inconvénients, la présente invention a pour objet des moyens permettant de séparer les feuilles ainsi aspirées, du flux d'air les oyant aspirées. This rejection, with the air stream, which can have drawbacks, the present invention relates to means making it possible to separate the sheets thus sucked, from the air flow oying them sucked.
A titre d'exemples non limitatifs et pour faciliter la compréhension de l'invention, on a représenté aux dessins onnexes :
Figure 1g une vue en élévation latérale, en coupe, d'un premier mode de réalisation de l'invention.By way of nonlimiting examples and to facilitate understanding of the invention, the accompanying drawings show:

Figure 4, une vue en élévation latérale, en coupe, d'un troisième mode de réalisation de l'invention. Figure 3, a sectional view along AA of Figure 2
Figure 4, a side elevational view, in section, of a third embodiment of the invention.
En se reportant à la figure 1, on voit que, selon un premier mode de réalisation, le dispositif comporte un capotage 1 comportant un orifice d'entrée 2 et un orifice de sortie 3. Referring to FIG. 1, it can be seen that, according to a first embodiment, the device comprises a casing 1 comprising an inlet port 2 and an outlet port 3.
Entre les deux sont disposés deux rouleaux 4 et 5 entre lesquels est tendue une boucle 6 constituée par un tamis souple. A l'intérieur de la boucle 6 est disposé un ventilateur 7, entraîné par un moteur 8.Between the two are arranged two rollers 4 and 5 between which is stretched a loop 6 constituted by a flexible screen. Inside the loop 6 is arranged a fan 7, driven by a motor 8.
De préférence, comme cela est représenté, le rouleau 5 est extérieur au capotage qui comporte deux fentes 9 et 10 pour laisser passer les deux brins du tamis en boucle 6. L'un au moins des deux rouleaux 4 ou 5 est moteur et entraîné par tout moyen approprié
L'ouverture 2 est protégée par des tringles longitudi nales 11 et peut comporter un outil de coupe qui, dans l'exemple représenté, est constitué par une pluralité de lames 12 coopérant avec des contre-lames 13, les lames 12 étant rayonnantes et entraînées en rotation par un moteur 14.Preferably, as shown, the roller 5 is outside the cowling which has two slots 9 and 10 to allow the two strands of the screen to pass in a loop 6. At least one of the two rollers 4 or 5 is powered and driven by any appropriate means
The opening 2 is protected by longitudi nal rods 11 and may include a cutting tool which, in the example shown, consists of a plurality of blades 12 cooperating with counterblades 13, the blades 12 being radiating and driven. in rotation by a motor 14.
De préférence, la partie de la boucle 6 qui se trouve entre l'outil de coupe et le ventilateur est soutenue par des galets 15. De préférence, également, une brosse circulaire 16 est disposée à la sortie 9 du capotage 1, pour éviter l'aspiration vers l'intérieur du coffre des feuilles sortant dudit capotage. Preferably, the part of the loop 6 which is located between the cutting tool and the fan is supported by rollers 15. Preferably, also, a circular brush 16 is disposed at the outlet 9 of the cowling 1, to avoid the suction towards the interior of the sheets leaving said cowling.
Le fonctionnement du dispositif ainsi décrit est le suivant : le ventilateur 7 est entraîné par le moteur 8, qui a une puissance relativement élevée, de l'ordre de 5 à 6 CV afin d'entrainer le ventilateur à une vitesse suffisante, environ 3000 t/m pour créer un courant d'aspiration important; le couteau rotatif est entrainé par le moteur 14 qui est de faible puissance, environ 0,5 CV soit environ le dixième de celle du moteur 8, la vitesse de rotation du couteau étant de l'ordre de 200 t/m, soit un peu moins du dixième de celle du ventilateur. The operation of the device thus described is as follows: the fan 7 is driven by the motor 8, which has a relatively high power, of the order of 5 to 6 CV in order to drive the fan at a sufficient speed, approximately 3000 t / m to create a large suction current; the rotary knife is driven by the motor 14 which is of low power, approximately 0.5 CV or approximately one tenth of that of the motor 8, the speed of rotation of the knife being of the order of 200 rpm, or a little less than a tenth of that of the fan.
Les feuilles aspirées par le courant d'air sont coupées par les lames 12, sans être hachées en morceaux très menus du fait que ces lames tournent asséz lentement. Les morceaux de feuilles viennent se plaquer contre le tamis 6. L'un ou l'autre des rouleaux 4 ou 5 étant entraîné par tout moyen approprié, la boucle 6 se déplace de façon continue, de sorte que la branche de la boucle qui sort par l'ouverture 9 évacue les feuilles coupées, hors du capotage 1. Les feuilles qui ne se détachent pas d'elles-mêmes du tamis sont brossées par la brosse 16, qui en plus évite la remontée de ces dernières dans le coffre. Il peut cependant arriver que certains morceaux de feuilles restent collés au tamis et dans ce cas ils seront détachés par le cou rant d'air en passant devant l'ouverture de sortie 3.The sheets sucked in by the air stream are cut by the blades 12, without being chopped into very small pieces because these blades rotate slowly. The pieces of leaves are pressed against the sieve 6. Either of the rollers 4 or 5 being driven by any suitable means, the loop 6 moves continuously, so that the branch of the loop that comes out through the opening 9 evacuates the cut sheets, out of the casing 1. The sheets which do not detach themselves from the sieve are brushed by the brush 16, which in addition prevents the latter from rising in the trunk. However, it can happen that certain pieces of leaves remain stuck to the sieve and in this case they will be detached by the air stream while passing in front of the outlet opening 3.
Du fait que les lames 12 sont entraînées à une vitesse relativement faible par un moteur 14 développant un couple également faible, les feuilles ne seront pas déchiquetées en morceaux très fins; d'autre part, l'outil de coupe n'ayant qu'une faible inertie pourra s'arrêter au contact de corps étrangers sans provoquer aucun dégat. De plus, la grande majorité des débris végétaux tombent sur le sol sans être projetés dans la végétation du vignoble. Because the blades 12 are driven at a relatively low speed by a motor 14 developing an equally low torque, the sheets will not be shredded into very fine pieces; on the other hand, the cutting tool having only a low inertia may stop in contact with foreign bodies without causing any damage. In addition, the vast majority of plant debris falls on the ground without being thrown into the vegetation of the vineyard.
On peut, comme cela est représenté à la figure 1, décaler les parois de la fente 9 par laquelle le tamis 6 sort du capotage; de telle sorte que la paroi du capotage, qui est située en avant du tamis, soit légèrement en amont de la paroi située en arrière, par rapport au sens de déplacement du tamis cette disposition permet aux feuilles de sortir du capotage 1 en étant toujours plaquées contre le tamis, et évite un bourrage de la fente 9. One can, as shown in Figure 1, shift the walls of the slot 9 through which the screen 6 comes out of the cover; so that the wall of the cover, which is located in front of the screen, is slightly upstream of the wall located behind, relative to the direction of movement of the screen this arrangement allows the sheets to exit from the cover 1 while still being pressed against the sieve, and prevents the slot 9 from jamming.
Les figures 2 et 3 représentent un deuxième mode de réalisation, dans lequel le capotage 1 est cylindrique et divisé en deux parties la et lb entre lesquelles est disposé un tamis circulaire 17, monté à rotation sur un arbre 18 et entrainé en rotation par tout moyen approprié dans le sens indiqué par la flèche. Les feuilles plaquées contre le tamis 17 par l'aspiration se détachent dans la zone située hors du capotage 1. Figures 2 and 3 show a second embodiment, in which the cover 1 is cylindrical and divided into two parts la and lb between which is disposed a circular screen 17, rotatably mounted on a shaft 18 and driven in rotation by any means appropriate in the direction indicated by the arrow. The sheets pressed against the sieve 17 by the suction come off in the area outside the cover 1.
La figure 4 représente un troisième mode de réalisa- tion dans lequel le tamis 19 interposé entre l'outil de coupe et le ventilateur est fixe, mais comporte des mailles en forme de fente, dans lesquelles passent des doigts 20 portés par des bielles 21, parallèles, montées à leurs deux extrémités sur deux disques rotatifs 22 et 23. Lorsque les disques 22 et 23 sont mis en mouvement (par tout moyen approprié non représenté), les doigts 20 "peignent" le tamis 19 et, de proche en proche, les feuilles et débris végétaux sont amenés jusqu'à l'ouverture inférieure 24 du capotage. FIG. 4 represents a third embodiment in which the screen 19 interposed between the cutting tool and the fan is fixed, but has meshes in the form of a slot, through which pass fingers 20 carried by connecting rods 21, parallel, mounted at their two ends on two rotary discs 22 and 23. When the discs 22 and 23 are set in motion (by any suitable means not shown), the fingers 20 "paint" the screen 19 and, step by step, the leaves and plant debris are brought to the lower opening 24 of the cowling.
