Description

La présente invention a pour objet un dispositif de pulvérisation de produit de traitement dans les cultures, et notamment adapté à la viticulture et l'arboriculture. On connaît déjà des dispositifs de pulvérisation de produit de traitement qui comprennent essentiellement des buses de pulvérisation disposées sur des rampes destinées à être portées par un châssis lui-même apte à être fixé sur un engin tracteur. De manière générale, dans les domaines de la viticulture et de l'arboriculture, les rampes sont disposées en sorte que les buses propulsent le produit de traitement en jets horizontaux, perpendiculairement au plan formé par la végétation. Il a également été proposé des procédés consistant à pulvériser les produits de traitement à partir un d'avion volant à basse altitude en sorte que le déplacement d'air permette d'une part de disperser le produit et d'agiter la végétation pour permettre une répartition homogène. De tels dispositifs sont toutefois réservés aux grandes étendues, et ne peuvent pas être utilisés pour les petites parcelles, dans le cas de la vigne notamment. The present invention relates to a device for spraying treatment product in crops, and in particular suitable for viticulture and arboriculture. Treatment product spraying devices are already known which essentially comprise spray nozzles arranged on ramps intended to be carried by a frame itself capable of being fixed on a tractor vehicle. Generally, in the fields of viticulture and arboriculture, the ramps are arranged so that the nozzles propel the treatment product in horizontal jets, perpendicularly to the plane formed by the vegetation. Methods have also been proposed for spraying the treatment products from a low-flying airplane so that the displacement of air on the one hand disperses the product and agitates the vegetation to allow homogeneous distribution. Such devices are however reserved for large areas, and can not be used for small parcels, in the case of the vine in particular.

Il a également été proposé de réaliser, pour les mêmes raisons que précédemment, la pulvérisation à partir d'un hélicoptère, permettant de réduire, sans toutefois le faire disparaître, l'inconvénient lié à la taille de cultures. Cependant, quel que soit l'engin volant utilisé, ces procédés présentent des inconvénients, outre ceux de coût et de surdimensionnement par rapport la taille de la majorité des cultures, il peut subsister après passages de l'engin, aussi bien des zones non traitées ou peu traitées, que des zones traitées deux fois. It has also been proposed to carry out, for the same reasons as above, spraying from a helicopter, to reduce, but not eliminate, the disadvantage related to the size of crops. However, whatever the flying machine used, these methods have drawbacks, besides those of cost and oversizing compared to the size of the majority of cultures, it can remain after passages of the machine, both untreated areas or little treated, only twice treated areas.

On connaît aussi des dispositifs de pulvérisateur tels que celui décrit dans le document FR 2 464 101, qui associe un atomiseur rotatif à un ventilateur, ce dernier créant un courant d'air apte à disperser les gouttelettes de produit de traitement générées par ledit atomiseur. Sprayers are also known, such as that described in document FR 2 464 101, which associates a rotary atomizer with a fan, the latter creating a stream of air capable of dispersing the droplets of treatment product generated by said atomizer.

La plupart de ces dispositifs présente l'inconvénient que la répartition du produit de traitement n'est pas optimisée, une partie de ce produit n'atteignant pas la végétation, ce qui est préjudiciable du point de vue coût et du point de vue environnemental. La présente invention a pour but de proposer un dispositif 5 de pulvérisation permettant de remédier aux divers inconvénients précités. Le dispositif de pulvérisation de produit de traitement dans les cultures, et notamment adapté à la viticulture et à l'arboriculture selon l'invention, est du type comprenant des 10 buses de pulvérisation de produit de traitement associées à des moyens de production de courants d'air, et il se caractérise essentiellement en ce qu'il comporte une structure support prévue apte à être portée par un engin mobile, et comprenant au moins une paire d'éléments verticaux disposés en vis-à-vis et 15 destinés à être positionnés de part et d'autre de la végétation à traiter, chacun desdits éléments comprenant au moins une buse de pulvérisation associée à un ventilateur pointés sensiblement horizontalement en direction de l'autre élément. Les ventilateurs des deux éléments verticaux créent deux 20 flux d'air qui s'affrontent au niveau de la végétation, produisant ainsi des remous dans lesquels est projeté le produit de traitement. Selon une caractéristique additionnelle du dispositif de pulvérisation selon l'invention, chaque ensemble d'une buse et 25 d'un ventilateur est associé à des moyens déflecteurs agencés au niveau de l'élément vertical. Selon une autre caractéristique additionnelle du dispositif de pulvérisation selon l'invention, les éléments déflecteurs présentent une orientation permettant de guider le flux d'air 30 produit par les ventilateurs. Selon une autre caractéristique additionnelle du dispositif de pulvérisation selon l'invention, il comporte des éléments déflecteurs orientables. Selon une autre caractéristique additionnelle du dispositif 35 de pulvérisation selon l'invention, chacun des éléments comporte en partie supérieure un ventilateur dirigé obliquement vers le bas et vers l'autre élément. Selon une autre caractéristique additionnelle du dispositif de pulvérisation selon l'invention, les deux éléments verticaux sont liés l'un à l'autre au travers d'une traverse de longueur réglable. Selon un mode de réalisation particulier du dis de pulvérisation selon l'invention, chacun des éléments verticaux comprend deux joues parallèles entretoisées par une pluralité de parois transversales qui forment avec lesdites joues des conduits d'axes sensiblement horizontaux, en regard desquels sont disposés les ventilateurs, et dans lesquels sont placées les buses de pulvérisation de produit de traitement. Les avantages et les caractéristiques du dispositif de pulvérisation selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. Dans le dessin annexé : -la figure 1 représente une vue schématique partielle en perspective d'un dispositif de pulvérisation selon l'invention. - la figure 2 représente une vue schématique en élévation de profil d'une partie du même dispositif. En référence à la figure 1, on peut voir qu'un dispositif de pulvérisation selon l'invention comprend une structure support 1 destinée à être assujettie à un engin tracteur non représenté, et qui comprend essentiellement deux éléments verticaux 2 séparés par un espace 10, et reliés supérieurement par une traverse 11 qui est prévue réglable en longueur en sorte de permettre de faire varier la largeur de l'espace 10. Most of these devices have the disadvantage that the distribution of the treatment product is not optimized, a portion of this product does not reach the vegetation, which is detrimental from the point of view of cost and environmental point of view. The object of the present invention is to propose a spraying device 5 making it possible to remedy the various aforementioned drawbacks. The spraying device for treatment product in crops, and in particular adapted to viticulture and arboriculture according to the invention, is of the type comprising treatment product spray nozzles associated with means for producing feed streams. air, and it is characterized essentially in that it comprises a support structure provided adapted to be carried by a mobile machine, and comprising at least one pair of vertical elements arranged vis-à-vis and 15 to be positioned on either side of the vegetation to be treated, each of said elements comprising at least one spray nozzle associated with a fan pointed substantially horizontally in the direction of the other element. The fans of the two vertical elements create two airflows which clash at the level of the vegetation, thus producing eddies in which the treatment product is projected. According to an additional feature of the spraying device according to the invention, each set of a nozzle and a fan is associated with deflector means arranged at the level of the vertical element. According to another additional feature of the spraying device according to the invention, the baffle elements have an orientation for guiding the air flow produced by the fans. According to another additional characteristic of the spraying device according to the invention, it comprises orientable deflector elements. According to another additional feature of the spraying device according to the invention, each of the elements comprises in the upper part a fan directed obliquely downwards and towards the other element. According to another additional feature of the spraying device according to the invention, the two vertical elements are connected to each other through a cross member of adjustable length. According to a particular embodiment of the sputtering according to the invention, each of the vertical elements comprises two parallel cheeks bridged by a plurality of transverse walls which form with said cheeks substantially horizontal axis ducts, opposite which are arranged the fans and in which the treatment product spray nozzles are placed. The advantages and characteristics of the spraying device according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof. In the accompanying drawing: FIG 1 shows a partial schematic perspective view of a spray device according to the invention. - Figure 2 shows a schematic side elevational view of part of the same device. With reference to FIG. 1, it can be seen that a spraying device according to the invention comprises a support structure 1 intended to be secured to a tractor vehicle, not shown, and which essentially comprises two vertical elements 2 separated by a space 10, and connected superiorly by a cross member 11 which is provided adjustable in length so as to make it possible to vary the width of the space 10.

Chacun des éléments 2 comprend deux joues latérales parallèles 20 entretoisées par une pluralité de parois transversales 21 qui forment avec les joues 20 des conduits 22 d'axes sensiblement horizontaux. La face extérieure de chacun des éléments 2, est équipée de 35 ventilateurs 3 disposés en sorte de souffler dans les conduits 22, vers l'espace 10. Each of the elements 2 comprises two parallel lateral cheeks 20 braced by a plurality of transverse walls 21 which form with the cheeks 20 ducts 22 of substantially horizontal axes. The outer face of each of the elements 2, is equipped with 35 fans 3 arranged so as to blow in the ducts 22, towards the space 10.

Chacun des éléments 2 comporte également des buses 4 de pulvérisation d'un produit de traitement, installées chacune en regard d'un conduit 22, en avant d'un ventilateur 3. De plus, chacun des éléments verticaux 2 est muni supérieurement d'un ventilateur 30, fixé de manière orientable à l'extrémité de bras 12 solidaire de la traverse 11, et essentiellement dirigé obliquement vers le bas et vers l'élément vertical 2 opposé. En pratique le support 1 est déplacé dans la culture à traiter de manière à enjamber la végétation 5 qui se trouve alors engagée dans l'espace 10. Le fonctionnement simultané des buses 4 et des ventilateurs 3 permet de créer u brouillard de produit de traitement. Les deux flux d'air créés par les ventilateurs 3 des deux éléments verticaux 2, s'affrontent et provoquent des turbulences au coeur de la végétation, permettant ainsi une répartition homogène du produit de traitement. Comme on peut le voir plus particulièrement sur la figure 22 qui représente un élément vertical 2, les parois transversales 21 qui font office de déflecteurs ne sont pas toutes parallèles, celles du haut sont de préférence inclinées vers le bas, tandis que celles dans bas sont inclinées vers le haut, et que les parois 21 intermédiaires sont sensiblement horizontales. Tout est conçu en sorte que le brouillard de produit émis par les buses 4, soit contenu par les différents flux d'air, et entièrement destiné au traitement de la végétation. Cette contention est par ailleurs améliorée par la mise en fonctionnement des ventilateurs 30. La répartition du produit de traitement sur la végétation est ainsi optimisée, ce qui, outre une efficacité maximale du traitement, autorise une économie de produit et d'eau, et évite de répandre un surplus de produit dans le sol. Selon une variante non représentée, les parois transversales 21, ou du moins certaines, notamment celles des extrémités haute et basse, sont conçues en sorte de pouvoir en modifier l'inclinaison à volonté. Each of the elements 2 also comprises nozzles 4 for spraying a treatment product, each installed next to a duct 22, in front of a fan 3. In addition, each of the vertical elements 2 is provided above fan 30, rotatably attached to the arm end 12 integral with the crosspiece 11, and essentially directed obliquely downwardly and towards the opposite vertical element 2. In practice the support 1 is moved in the culture to be treated so as to span the vegetation 5 which is then engaged in the space 10. The simultaneous operation of the nozzles 4 and the fans 3 allows to create a fog of treatment product. The two air flows created by the fans 3 of the two vertical elements 2, clash and cause turbulence in the heart of the vegetation, allowing a homogeneous distribution of the treatment product. As can be seen more particularly in FIG. 22, which represents a vertical element 2, the transverse walls 21 which act as deflectors are not all parallel, those at the top are preferably inclined downwards, whereas those at the bottom are inclined upwards, and that the intermediate walls 21 are substantially horizontal. Everything is designed so that the product mist emitted by the nozzles 4, is contained by the different air flows, and entirely for the treatment of vegetation. This compression is also improved by the operation of the fans 30. The distribution of the treatment product on the vegetation is thus optimized, which, in addition to maximum efficiency of treatment, allows a saving of product and water, and avoids to spread a surplus of product in the soil. According to a variant not shown, the transverse walls 21, or at least some, including those of the upper and lower ends, are designed so as to change the inclination at will.
