Abstract

The additional fluid injector for an agricultural fluid spray boom injects the additional fluid directly to the inlet to the boom to reduce the delay of the fluid input. The injector has a remote control (1) and a tank (2) for a feed (4) connected to a pump (3). A pressure regulator is connected to a distributor (6) for the liquid to each of the electro valves (7) for each injector (8).

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

L'invention concerne un dispositif destine aux pulvérisateurs à rampes tel que décrit sur la figure 1 comportant au départ une cuve principale, (10), une pompe principale (ll), des vannes de répartition (12), une rampe (13), comprenant des sections de rampe (14), des tuyaux d'alimentation (15), et des buses de pulvérisation (16). Le dispositif tel que décrit sur la figure 2, permet d'injecter un ou plusieurs fluides supplémentaires à l'entrée de chaque section formant la rampe d'épandage du pulvérisateur. The invention relates to a device intended for boom sprayers as described in FIG. 1 initially comprising a main tank (10), a main pump (ll), distribution valves (12), a ramp (13), comprising boom sections (14), supply hoses (15), and spray nozzles (16). The device as described in FIG. 2 makes it possible to inject one or more additional fluids at the entrance to each section forming the sprayer boom.

L'invention s'applique en particulier pour l'injection dans la rampe de désherbants, produits phytosanitaires, ou d'engrais liquides lors de la pulvérisation d'un fluide. The invention applies in particular to the injection into the boom of weedkillers, phytosanitary products, or liquid fertilizers during the spraying of a fluid.

Plusieurs types de dispositifs visant cet objectif existent sur le marché, cependant ils présentent tous l'inconvénient d'injecter le fluide très en amont de la rampe d'épandage entre la pompe principale et les Vannes de répartition du pulvérisateur. La longueur et le diamètre important des tuyaux d'alimentation du pulvérisateur engendrent un délais d'arrivée du fluide important jusqu'aux buses alors que le pulvérisateur continue sa progression dans le champ si bien qu'il est difficile d'évaluer l'endroit ou sera injecté le fluide, et d'atteindre les zones à traiter et aussi d'arrêter l'arrivée du fluide en dehors des zones à traiter, tant que les tuyaux d'alimentation du pulvérisateur contiennent du fluide. Several types of devices for this purpose exist on the market, however they all have the disadvantage of injecting the fluid very upstream of the spreading ramp between the main pump and the sprayer distribution valves. The length and the large diameter of the sprayer supply hoses cause a delay in the arrival of significant fluid to the nozzles while the sprayer continues its progression in the field so that it is difficult to assess the place or the fluid will be injected, and reach the areas to be treated and also to stop the arrival of the fluid outside the areas to be treated, as long as the supply pipes of the sprayer contain fluid.

L'invention permet de remédier à cet inconvénient. Le dessin représenté sur la figure 1 représente l'art antérieur. La figure 2 représente le dispositif selon l'invention : un boîtier de commende électrique (1) permet d'actionner la pompe (3) et simultanément une ou plusieurs électrovannes (7) correspondant respectivement à chaque tronçon de rampe (13) forment la rampe du pulvérisateur (14). The invention overcomes this drawback. The drawing shown in Figure 1 represents the prior art. FIG. 2 represents the device according to the invention: an electrical control box (1) makes it possible to actuate the pump (3) and simultaneously one or more solenoid valves (7) corresponding respectively to each section of ramp (13) form the ramp of the sprayer (14).

Le fluide contenu dans le réservoir auxiliaire (2) amené par la pompe (3) traverse le régulateur de pression (5) qui permet d'ajuster la quantité de The fluid contained in the auxiliary tank (2) supplied by the pump (3) passes through the pressure regulator (5) which makes it possible to adjust the quantity of

fluide à injecter, le surplus de fluide étant retourné au réservoir auxiliaire (2) tandis que la quantité désirée de fluide circule par les tuyaux souples (4) jusqu'au répartiteur (6) formé d'une chambre avec une entrée et autant de sorties que de tronçons de rampe (13) chaque tronçon (13) étant équipé d'une électrovanne (7) située a quelques centimètres de l'entrée de chaque tronçon (13), elle commande l'ouverture ou la fermeture de l'arrivée du fluide vers l'injecteur (8) constitué d'un cylindre de plastique obstruant la conduite et percé d'un trou calibré. Il a pour but de répartir de façon homogène le flux de fluide dans chaque section de rampe (14) en particulier lors de la pulvérisation en travers de pente, afin d'éviter qu'une quantité plus importante de fluide ne soit diffusée dans les tronçons les plus bas de la rampe.  fluid to be injected, the surplus fluid being returned to the auxiliary tank (2) while the desired quantity of fluid flows through the flexible pipes (4) to the distributor (6) formed by a chamber with an inlet and as many outlets as ramp sections (13) each section (13) being equipped with a solenoid valve (7) located a few centimeters from the inlet of each section (13), it controls the opening or closing of the arrival of the fluid to the injector (8) consisting of a plastic cylinder obstructing the pipe and pierced with a calibrated hole. Its purpose is to distribute the fluid flow evenly in each boom section (14), in particular when spraying across the slope, in order to prevent a larger quantity of fluid from being diffused in the sections the lowest of the ramp.

Le fluide arrive ensuite dans le T mélangeur (9) situé à proximité immédiate de chaque section de rampe (13). The fluid then arrives in the T mixer (9) located in the immediate vicinity of each ramp section (13).

Constitué de deux entrées correspondant aux diamètres intérieurs de la conduite de tuyaux souples (15) du pulvérisateur dans lequel il vient s'insérer, et d'une entrée correspondant au diamètre intérieur du tuyau souple amenant le fluide dans le T mélangeur (9), il a pour but de mélanger le fluide avec le support liquide contenu dans la cuve principale (10) pulvérisé par les buses de la rampe (16). Consisting of two inlets corresponding to the inside diameters of the flexible pipe line (15) of the sprayer into which it is inserted, and an inlet corresponding to the inside diameter of the flexible pipe bringing the fluid into the mixer T (9), its purpose is to mix the fluid with the liquid support contained in the main tank (10) sprayed by the nozzles of the boom (16).

La proximité immédiate du T mélangeur (9) avec la section de rampe permet une réponse quasi instantané au problème posé sur le terrain et donc de traiter localement ce problème, générant ainsi des économies importantes de produits, et de nombreux passages de pulvérisateur Le boîtier de commande sert également à actionner un dispositif servant a l'éradication des mauvaises herbes situées en bordure de champ. Constitué d'un réservoir contenant un désherbant non sélectif de contact, d'une pompe électrique amenant au moyen de tuyaux souples à une électrovanne puis à une buse de pulvérisation située à l'une des extrémités de la rampe.The immediate proximity of the mixer T (9) to the boom section allows an almost instantaneous response to the problem posed in the field and therefore to locally treat this problem, thus generating significant savings in products, and numerous sprayer passages. control is also used to activate a device used to eradicate weeds located at the edge of the field. Consisting of a tank containing a non-selective contact weedkiller, an electric pump bringing by means of flexible pipes to a solenoid valve and then to a spray nozzle located at one end of the boom.
