Cette Buse (2) pour dispositif de pulvérisation comprenant, à son extrémité distale, un pavillon (5) dont l'ouverture (51) comprend au moins une dent (54, 55, 56). Avantageusement, la présence de dent à l'ouverture de sortie de la buse ou de picots et/ou lames à l'intérieur de la buse tend à perturber l'écoulement du jet d'air. En cas de feuille formant écran au jet d'air, le jet d'air ainsi rendu turbulent, augmente ses chances de dévier la feuille écran et ainsi augmente la pénétration du traitement dans le feuillage.The nozzle (2) for spraying device comprising, at its distal end, a horn (5) whose opening (51) comprises at least one tooth (54, 55, 56). Advantageously, the presence of tooth at the outlet opening of the nozzle or pins and / or blades inside the nozzle tends to disturb the flow of the air jet. In the case of an air-jet screen sheet, the jet of air thus rendered turbulent increases its chances of deflecting the screen sheet and thus increases the penetration of the treatment in the foliage.
Description
La présente invention concerne une buse pour un dispositif de pulvérisation. Un dispositif de pulvérisation est classiquement utilisé, porté par une machine agricole, tel un tracteur ou une remorque, afin de parcourir une plantation de végétaux, avantageusement en ligne, tel des arbres ou de la vigne, et permettre de pulvériser sur lesdits végétaux un produit phytosanitaire.The present invention relates to a nozzle for a spraying device. A spraying device is conventionally used, carried by an agricultural machine, such as a tractor or a trailer, in order to travel through a planting of plants, advantageously in line, such as trees or vines, and make it possible to spray a product on said plants. plant.
Afin de réaliser la pulvérisation, un circuit d'air apporte un air propulseur jusqu'à une buse. L'air propulseur entre par une entrée de la buse, la traverse de part en part et ressort par une ouverture en sortie, sous forme d'un jet d'air dirigé vers les végétaux à traiter. La buse assure une fonction de mise en forme du jet d'air et sa distribution vers les végétaux à traiter. Le produit phytosanitaire est dispersé à l'ouverture de sortie de la buse afin d'être porté ou soufflé par le jet d'air dans le feuillage des végétaux à traiter.In order to carry out the spraying, an air circuit brings propellant air to a nozzle. The propellant air enters through an inlet of the nozzle, crosses it right through and exits through an opening at the outlet, in the form of a jet of air directed towards the plants to be treated. The nozzle performs a function of shaping the air jet and its distribution towards the plants to be treated. The phytosanitary product is dispersed at the outlet opening of the nozzle in order to be carried or blown by the air jet in the foliage of the plants to be treated.
Il peut arriver que le jet d'air rencontre une feuille d'un des végétaux, sensiblement transverse au jet d'air, et formant écran. Un tel écran est pénalisant en ce qu'il empêche une pénétration profonde dans l'épaisseur du feuillage du produit phytosanitaire.It may happen that the air jet meets a leaf of one of the plants, substantially transverse to the air jet, and forming a screen. Such a screen is penalizing in that it prevents deep penetration into the thickness of the foliage of the plant protection product.
Aussi il est recherché un moyen d'éviter ou d'atténuer les effets de ce problème.Also a way is being sought to avoid or mitigate the effects of this problem.
La présente invention remédie à cet inconvénient en proposant une buse pour dispositif de pulvérisation comprenant, à son extrémité distale, un pavillon dont l'ouverture comprend au moins une dent.The present invention overcomes this drawback by proposing a nozzle for a spraying device comprising, at its distal end, a horn, the opening of which comprises at least one tooth.
Selon une autre caractéristique, tout le contour de l'ouverture est dentelé.According to another characteristic, the entire outline of the opening is serrated.
Selon une autre caractéristique, une dent présente une hauteur et/ou une largeur comprise entre 1 et 50% de la longueur de l'ouverture.According to another characteristic, a tooth has a height and / or a width of between 1 and 50% of the length of the opening.
Selon une autre caractéristique l'intérieur de la buse, tel l'intérieur du pavillon, comprend des picots et/ou des lames.According to another characteristic, the interior of the nozzle, such as the interior of the roof, comprises pins and / or blades.
Selon une autre caractéristique, la buse comprend encore un boisseau rotatif disposé dans le pavillon, où l'intérieur du boisseau comprend des picots et/ou des lames.According to another characteristic, the nozzle also comprises a rotary plug placed in the roof, where the interior of the plug comprises pins and / or blades.
Selon une autre caractéristique, une picot ou une lame présente une hauteur comprise entre 1 et 50% de la longueur de 1'ouverture.According to another characteristic, a pin or a blade has a height of between 1 and 50% of the length of the opening.
Avantageusement, la présence de dent à l'ouverture de sortie de la buse ou de picots et/ou lames à l'intérieur de la buse tend à perturber l'écoulement du jet d'air. En cas de feuille formant écran au jet d'air, le jet d'air ainsi rendu turbulent, augmente ses chances de dévier la feuille écran et ainsi augmente la pénétration du traitement dans le feuillage.Advantageously, the presence of a tooth at the outlet opening of the nozzle or of pins and / or blades inside the nozzle tends to disturb the flow of the air jet. In the case of a sheet forming a screen with an air jet, the air jet thus made turbulent, increases its chances of deflecting the screen sheet and thus increases the penetration of the treatment into the foliage.
L'invention concerne encore un dispositif de pulvérisation, comprenant une telle buse.The invention also relates to a spraying device, comprising such a nozzle.
D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description détaillée donnée ci-après à titre indicatif en relation avec des dessins sur lesquels :Other characteristics, details and advantages of the invention will emerge more clearly from the detailed description given below by way of indication in relation to the drawings in which:
- la figure 1-5 illustrent en vue perspective un mode de réalisation possible d'une buse selon l'invention,FIG. 1-5 illustrate in perspective view a possible embodiment of a nozzle according to the invention,
- les figures 1 et 2 présente une buse entière,- Figures 1 and 2 shows an entire nozzle,
- les figures 3 et 4 présente une buse coupée selon un plan longitudinal,FIGS. 3 and 4 show a nozzle cut along a longitudinal plane,
- la figure 5 présente une vue éclatée.- Figure 5 shows an exploded view.
Une buse 2 forme une conduite apte à transporter l'air propulseur, typiquement issu d'une turbine.A nozzle 2 forms a pipe capable of transporting the propellant air, typically coming from a turbine.
Tel que plus particulièrement visible à la figure 1, l'air entre par une entrée d'air 31 pratiquée dans un manchon 3. L'air arrive typiquement du haut. Il est dévié par un coude dans le manchon 3, afin de poursuivre son parcours sensiblement horizontalement. Le manchon 3 est prolongé, en continuité, par un pavillon 5 en charge de la diffusion de l'air propulseur. Tel que plus particulièrement visible à la figure 2 le pavillon 5 forme l'extrémité distale de la buse 2 et se termine au niveau de son ouverture 51. On entend ici par ouverture le bord terminal du pavillon 5.As more particularly visible in Figure 1, the air enters through an air inlet 31 formed in a sleeve 3. The air typically arrives from the top. It is deflected by an elbow in the sleeve 3, in order to continue its course substantially horizontally. The sleeve 3 is extended, in continuity, by a pavilion 5 in charge of the diffusion of the propellant air. As more particularly visible in FIG. 2, the pavilion 5 forms the distal end of the nozzle 2 and ends at its opening 51. The term “opening” is understood here to mean the terminal edge of the pavilion 5.
Selon une caractéristique importante, cette ouverture 51 du pavillon 5 comprend au moins une dent 54, 55, 56. L'objectif de cette au moins une dent 54, 55, 56 est de perturber le jet d'air sortant de la buse afin de le rendre turbulent, de manière à agiter les feuilles, pour augmenter la pénétration du produit phytosanitaire et éviter un risque de masquage par une feuille écran.According to an important characteristic, this opening 51 of the roof 5 comprises at least one tooth 54, 55, 56. The objective of this at least one tooth 54, 55, 56 is to disturb the jet of air leaving the nozzle in order to make it turbulent, so as to agitate the leaves, to increase the penetration of the plant protection product and avoid a risk of masking by a screen sheet.
La présence de dents 53, 54, 55 le long du contour de l'ouverture 51 est d'autant plus avantageusement perturbante pour le jet d'air que les dents recouvrent une longueur importante du contour de l'ouverture 51. Aussi selon un mode de réalisation préférentiel tout le contour de l'ouverture 51 est dentelé.The presence of teeth 53, 54, 55 along the contour of the opening 51 is all the more advantageously disturbing for the air jet as the teeth cover a significant length of the contour of the opening 51. Also according to one embodiment of preferred embodiment the entire outline of the opening 51 is serrated.
Selon le mode de réalisation illustré, le pavillon 5 est configurable au moyen de deux volets 52, 53 mobiles relativement au corps 57 de pavillon, afin de varier la taille de l'ouverture 51. Aussi le contour de l'ouverture 51 est partagé entre les trois pièces 57, 52, 53. Aussi, au moins une dent 54 est disposée sur la partie de l'ouverture 51 réalisée par le corps 57, au moins une dent 55 est disposée sur la partie de l'ouverture 31 réalisée par le volet 52 et au moins une dent 56 est disposée sur la partie de l'ouverture 51 réalisée par le volet 53.According to the illustrated embodiment, the roof 5 is configurable by means of two flaps 52, 53 movable relative to the body 57 of the roof, in order to vary the size of the opening 51. Also the outline of the opening 51 is shared between the three parts 57, 52, 53. Also, at least one tooth 54 is disposed on the part of the opening 51 produced by the body 57, at least one tooth 55 is disposed on the part of the opening 31 produced by the flap 52 and at least one tooth 56 is disposed on the part of the opening 51 produced by the flap 53.
Ces dents 53, 54, 55 présentent un profil quelconque, par exemple triangulaire. La hauteur et/ou le module d'une dent 53, 54, 55 est compris entre 1 et 50% de la longueur de l'ouverture 21 du pavillon 5.These teeth 53, 54, 55 have any profile, for example triangular. The height and / or modulus of a tooth 53, 54, 55 is between 1 and 50% of the length of the opening 21 of the roof 5.
Un effet créateur de turbulences important est obtenu par des dents 53, 54, 55 disposées sur l'ouverture 51. Cet effet peut encore être augmenté en disposant à l'intérieur, par exemple sur au moins une paroi interne de la buse 2, des picots 82 et/ou des lames 81. On entend ici par paroi interne de préférence une paroi en contact avec le flux d'air lors de sa traversée de la buse 2. Ces picots 82 et/ou lames 81, d'extension sensiblement transverse à la direction du flux d'air ont pour objectif de perturber l'écoulement de l'air lorsqu'il traverse la buse 2 et particulièrement lorsqu'il longe les parois internes. Une paroi tapissée de picots et/ou de lames peut être toute paroi interne. Il peut s'agir de la paroi interne du manchon 3. Cependant l'effet perturbateur obtenu est d'autant plus important que l'on se rapproche de la sortie. Aussi la paroi interne du pavillon 5 est préférée.A significant turbulence-creating effect is obtained by teeth 53, 54, 55 disposed on the opening 51. This effect can be further increased by placing inside, for example on at least one internal wall of the nozzle 2, pins 82 and / or blades 81. The term “internal wall” is preferably understood here to mean a wall in contact with the air flow when it passes through the nozzle 2. These pins 82 and / or blades 81, of substantially transverse extension to the direction of the air flow are intended to disturb the flow of air when it passes through the nozzle 2 and particularly when it runs along the internal walls. A wall lined with pins and / or blades can be any internal wall. It may be the internal wall of the sleeve 3. However, the disturbing effect obtained is all the more important the closer one gets to the outlet. Also the inner wall of the pavilion 5 is preferred.
Les picots 82 sont sensiblement ponctuels et présentent une hauteur comprise entre 1 et 50% de la longueur de l'ouverture 51 du pavillon 5. Les lames 81 présentent des formes quelconques, par exemple linéaires ou en vagues, de longueurs quelconques. Les lames 81 présentent une hauteur comprise entre 1 et 50% de la longueur de l'ouverture 51 du pavillon 5.The pins 82 are substantially punctual and have a height between 1 and 50% of the length of the opening 51 of the roof 5. The blades 81 have any shapes, for example linear or in waves, of any length. The blades 81 have a height of between 1 and 50% of the length of the opening 51 of the roof 5.
Selon une autre caractéristique, plus particulièrement visible aux figures 3-5, la buse 2 comprend encore un moyen d'obturation 8, sous la forme d'un boisseau 8. Ce boisseau 8 est disposé, avantageusement dans le pavillon 5 et sa rotation permet de varier la section utile du pavillon 5/de la buse 2. La figure 3 montre un boisseau 8 ouvert et la figure 4 montre un boisseau 8 fermé.According to another characteristic, more particularly visible in Figures 3-5, the nozzle 2 further comprises a closure means 8, in the form of a plug 8. This plug 8 is arranged, advantageously in the pavilion 5 and its rotation allows to vary the useful section of the roof 5 / of the nozzle 2. FIG. 3 shows a plug 8 open and FIG. 4 shows a plug 8 closed.
Dans ce cas les parois internes en contact avec l'air ne sont plus celles du pavillon 5, mais celles du boisseau 8. Aussi, les parois internes du boisseau 8 comprennent des picots 82 et/ou des lames 81. A noter que le boisseau 8 tel que représenté comporte deux ouvertures de passage de l'air et donc quatre parois internes. Les deux parois centrales sont ici recouvertes de lames 81, tandis que les deux parois latérales sont recouvertes de picots 82. Un tel arrangement est bien sûr illustratif.In this case the internal walls in contact with the air are no longer those of the roof 5, but those of the plug 8. Also, the internal walls of the plug 8 include pins 82 and / or blades 81. Note that the plug 8 as shown has two air passage openings and therefore four internal walls. The two central walls are here covered with blades 81, while the two side walls are covered with pins 82. Such an arrangement is of course illustrative.
L'invention concerne encore un dispositif de pulvérisation comprenant une telle buse 2.The invention also relates to a spraying device comprising such a nozzle 2.
Cette buse est plus communément appelée diffuseur.This nozzle is more commonly called a diffuser.
Selon un mode de réalisation alternatif ce diffuseur comprend un canal destiné à porter l'air de son entrée à sa sortie. Ce canal est muni d'au moins une protubérance conformé pour agir sur le flux d'air. Par agir on comprend que les protubérances peuvent guider le flux d'air. Elle s'apparente alors à des lamelles comme on peut le voir sur la partie droite de la figure 4.According to an alternative embodiment, this diffuser comprises a channel intended to carry air from its inlet to its outlet. This channel is provided with at least one protuberance shaped to act on the air flow. By acting we understand that the protrusions can guide the air flow. It then looks like lamellae as can be seen on the right-hand side of FIG. 4.
Alternativement les protubérances peuvent perturber le flux d'air en sortie du diffuseur. Ces protubérances présentent alors la forme de picot et/ou de nervures disposées dans le canal.Alternatively, the protrusions can disturb the air flow at the outlet of the diffuser. These protrusions then have the shape of a spike and / or of ribs arranged in the channel.
Alternativement les protubérances sont complétées et/ou remplacées par des éléments rapportés dans le canal.Alternatively, the protuberances are supplemented and / or replaced by elements added in the channel.
Selon une alternative le diffuseur ne comprend pas de volets mobiles en sortie.According to an alternative, the diffuser does not include movable flaps at the outlet.
Il est bien évidemment possible de combiner les différents modes de réalisation décrit dans cette demande.It is obviously possible to combine the different embodiments described in this application.
