TITOLO: LANCIA EROGATRICE MISCELATRICE DI SOSTANZE PESTICIDE E/O LARVICIDE TITLE: LANCE DISPENSER MIXING OF PESTICIDE AND / OR LARVICIDE SUBSTANCES
CAMPO DI APPLICAZIONE DELL'INVENZIONE FIELD OF APPLICATION OF THE INVENTION
Il presente trovato si inserisce nel campo dei dispositivi di disinfestazione per irrorazione di una miscela di acqua con sostanze pesticide e larvicide. The present invention falls within the field of disinfestation devices for spraying a mixture of water with pesticidal and larvicidal substances.
Specificamente si tratta di un erogatore miscelatore che consente di addizionare direttamente all'acqua una sostanza liquida avente caratteristiche pesticida e/o larvicida, al fine di bloccare la proliferazione larvale oltre ché allontanare il problema degli insetti e delle zanzare che affliggono, specialmente d'estate, la popolazione. Specifically, it is a mixer dispenser that allows you to add a liquid substance with pesticidal and / or larvicidal characteristics directly to the water, in order to block larval proliferation as well as remove the problem of insects and mosquitoes that afflict, especially in summer. , the population.
Sono già diffusi alcuni metodi atti a ridurre la proliferazione larvicida ed in particolare: Some methods are already widespread to reduce larvicidal proliferation and in particular:
• interventi aerei nei campi coltivati, nelle risaie ed in altri focolai di sviluppo larvale ad esse limitrofe, a mezzo elicottero, • aerial interventions in the cultivated fields, in the rice fields and in other centers of larval development adjacent to them, by helicopter,
· trattamenti dell'acqua nei tombini, vasi, fioriere, griglie di scarico, pozzetti di raccolta delle acque meteoriche, Water treatments in manholes, vases, planters, drain grates, rainwater collection pits,
• bonifiche di tombini di raccolta delle acque piovane prima dell'avvio di ogni ciclo di trattamento larvicida; • reclamation of rainwater collection manholes before the start of each larvicide treatment cycle;
In ogni caso tutti quegli accorgimenti atti ad evitare il ristagno delle acque meteoriche o di qualsiasi altra provenienza. In any case, all those precautions aimed at avoiding the stagnation of rainwater or any other source.
La periodicità dei trattamenti è congruente alla tipologia del prodotto usato, secondo le indicazioni riportate in etichetta; indipendentemente dalla periodicità. The frequency of treatments is congruent to the type of product used, according to the indications on the label; regardless of the periodicity.
L'inconveniente delle metodologie sopra descritte, specie quelli eseguiti negli spazi di proprietà privata, riguarda il fatto che, sebbene utilizzanti prodotti di sicura efficacia larvicida, essi devono essere pre-miscelati con una certa dose di acqua (in un apposito serbatoio) dopodiché la miscela così creata può essere erogata. Da ciò ne consegue due tipologie di erogazione, la prima manuale e la seconda automatizzata; nel primo caso l'utilizzatore deve caricarsi del peso del serbatoio di miscela e con comando manuale mettere in pressione detto serbatoio per poi erogare la miscela. Nel secondo caso, qualora non si voglia ricorrere all'azionamento manuale, si deve aggravare il sistema della motorizzazione necessaria allo scopo, motorizzazione che appesantisce in maniera considerevole il carico suN'utilizzatore. The drawback of the methods described above, especially those performed in privately owned spaces, concerns the fact that, although using products of certain larvicidal efficacy, they must be pre-mixed with a certain dose of water (in a special tank) after which the mixture thus created can be dispensed. This results in two types of dispensing, the first manual and the second automated; in the first case, the user must load the weight of the mixture tank and with manual control pressurize said tank and then dispense the mixture. In the second case, if you do not want to resort to manual operation, you have to worsen the system of the motorization necessary for the purpose, motorization that considerably weighs down the load on the user.
In aggiunta, i metodi descritti sebbene abbastanza efficaci, devono essere ripetuti periodicamente dall'utilizzatore, sia nell'area verde che sull'acqua stagnante, quale quella dei tombini o dei sottovasi o delle vasche di raccolta; intervento che alla lunga può risultare tedioso e disincentivante per la persona stessa. In addition, the methods described, although quite effective, must be repeated periodically by the user, both in the green area and on stagnant water, such as that of manholes or saucers or collection tanks; intervention that in the long run can be tedious and disincentive for the person himself.
ESPOSIZIONE E VANTAGGI DEL TROVATO EXPOSURE AND ADVANTAGES OF THE FOUND
Scopo del presente trovato è quello di mettere a disposizione dell'utilizzatore e della tecnica un differente metodo e sistema di erogazione delle sostanze pesticide e larvicide, idoneo ad essere iniettato attraverso una lancia erogatrice man mano che il flusso di acqua viene diffuso attraverso quest'ultima. The purpose of the present invention is to provide the user and the technician with a different method and system for dispensing the pesticide and larvicide substances, suitable for being injected through a dispensing lance as the flow of water is diffused through the latter. .
Ulteriore scopo del trovato è quello di fornire una lancia erogatrice in grado di garantire l'introduzione nel flusso principale di una quantità prestabilita di sostanza pesticida, così da rispettare i rapporti acqua/disinfestante per un'efficace azione di disinfestazione. A further object of the invention is to provide a dispensing lance capable of guaranteeing the introduction into the main flow of a predetermined quantity of pesticide substance, so as to respect the water / disinfestant ratio for an effective disinfestation action.
Il dispositivo erogatore qui descritto consente pertanto di diffondere il veleno, antizanzare o altri insetti fastidiosi sia per l'uomo che nocivi per le piante, con una semplice prolunga vaporizzatrice, direttamente attaccato al tubo dell'acqua della rete idrica. The dispensing device described here therefore allows to spread the poison, mosquitoes or other annoying insects both for humans and harmful for plants, with a simple steaming extension, directly attached to the water pipe of the water mains.
Quanto sopra limita il peso dell'attrezzatura necessaria, evitando l'impiego di serbatoi a spalla e riducendo il peso gravante sull'utilizzatore. In aggiunta è un dispositivo che potrà essere utilizzato come normale erogatore qualora non si utilizzi il serbatoio aggiuntivo, come descritto in seguito. The above limits the weight of the necessary equipment, avoiding the use of shoulder tanks and reducing the weight on the user. In addition, it is a device that can be used as a normal dispenser if the additional tank is not used, as described below.
Altro vantaggio è relativo alla rigenerazione del sistema proposto, che potrà essere compiuta dall'utilizzatore medesimo e al momento opportuno. Another advantage relates to the regeneration of the proposed system, which can be carried out by the user himself and at the appropriate time.
Infine, in alternativa, sistemi a cartuccia in pressione, del tipo usa e getta o vuoto a rendere, potranno essere impiegati in sostituzione del serbatoio qui descritto. Finally, alternatively, pressurized cartridge systems, of the disposable or returnable type, can be used to replace the tank described here.
Detti scopi e vantaggi sono tutti raggiunti dalla lancia erogatrice miscelatrice di sostanze pesticide e/o larvicide, oggetto del presente trovato, che si caratterizza per quanto previsto nelle sotto riportate rivendicazioni. Said objects and advantages are all achieved by the dispensing lance for mixing pesticide and / or larvicide substances, object of the present invention, which is characterized by what is provided for in the appended claims.
BREVE DESCRIZIONE DELLE FIGURE BRIEF DESCRIPTION OF THE FIGURES
Questa ed altre caratteristiche risulteranno maggiormente evidenziate dalla descrizione seguente di alcune forme di realizzazione illustrate, a puro titolo esemplificativo e non limitativo nelle unite tavole di disegno. This and other characteristics will become more evident from the following description of some embodiments illustrated, purely by way of non-limiting example in the accompanying drawing tables.
Figura 1: illustra la lancia erogatrice oggetto del trovato Figure 1: illustrates the dispensing lance according to the invention
DESCRIZIONE DEL TROVATO DESCRIPTION OF THE FOUND
Con particolare riferimento alla figura, si indica con 1, nel suo complesso, una lancia 1 erogatrice miscelatrice di sostanze 12 pesticide e/o larvicide. With particular reference to the figure, 1 indicates, as a whole, a dispensing lance 1 for mixing pesticide and / or larvicidal substances 12.
La lancia 1 comprende una impugnatura 2, preferibilmente ergonomica, da impugnare all'atto della erogazione. The lance 1 comprises a handle 2, preferably ergonomic, to be gripped when dispensing.
All'Interno di detta impugnatura 2 è presente, non visibile, un condotto idoneo a convogliare il fluido, l'acqua, da un ingresso 3 verso una uscita 4. Inside said handle 2 there is, not visible, a conduit suitable for conveying the fluid, water, from an inlet 3 to an outlet 4.
Detto ingresso 3 è a sua volta idoneo a poter essere agganciato a una sorgente 5 di erogazione dell'acqua, nella fattispecie è convogliata tramite un tubo 5 di irrigazione posto in derivazione con la rete idrica. Ciò reca il vantaggio di non dover necessitare di un serbatoio di acqua premiscelato. Said inlet 3 is in turn suitable for being coupled to a water supply source 5, in this case it is conveyed through an irrigation pipe 5 placed in derivation with the water network. This has the advantage of not having to need a premixed water tank.
L'ingresso 3 è agganciabile al tubo 5 mediante relativi mezzi 8 di aggancio e collegamento, quali ad esempio mezzi di aggancio rapido. The inlet 3 can be coupled to the tube 5 by means of relative coupling and connection means 8, such as for example quick coupling means.
Si osserva anche la presenza di una prolunga 6 che si protrae dalla uscita 4 della lancia. La prolunga 6 termina con almeno un ugello 9 nebulizzatore che migliora l'azione nebulizzante e diffusiva del pesticida. It is also observed the presence of an extension 6 which extends from the outlet 4 of the lance. The extension 6 ends with at least one nebulizer nozzle 9 which improves the nebulizing and diffusive action of the pesticide.
Sull'impugnatura è presente un organo 7 di comando la cui funzione è di intercettare il fluido di passaggio nel condotto, regolando la sua apertura e chiusura della sezione di passaggio. On the handle there is a control member 7 whose function is to intercept the fluid passing through the duct, regulating its opening and closing of the passage section.
Nella fattispecie l'organo 7 è una leva, ovvero un grilletto che tramite corrispondenti leverismi intercetta il fluido, in maniera nota. In this case the member 7 is a lever, that is a trigger which, by means of corresponding levers, intercepts the fluid, in a known way.
La lancia comprende superiormente una valvola 10 unidirezionale; la valvola 10 è solidale con almeno una unità 11 di carica e contenimento della sostanza 12 da miscelare con l'acqua e diffondere. The lance comprises a one-way valve 10 at the top; the valve 10 is integral with at least one unit 11 for charging and containing the substance 12 to be mixed with water and diffused.
La fuoriuscita di detta sostanza avviene per mezzo della pressione interna a detta unità di carica 11, cosicché all'apertura della valvola 10 la sostanza 12 è libera di entrare nel condotto interno in attraversamento dal fluido. The outflow of said substance occurs by means of the pressure inside said charge unit 11, so that when the valve 10 is opened the substance 12 is free to enter the internal duct through which the fluid flows.
Secondo una forma preferita di realizzazione, un primo azionamento della leva di comando, indicata con 7, apre il condotto principale dell'acqua, mentre un'ulteriore azionamento della leva apre anche la valvola 10 consentendo la fuoriuscita della sostanza 12 come precedentemente descritto. According to a preferred embodiment, a first actuation of the control lever, indicated with 7, opens the main water duct, while a further actuation of the lever also opens the valve 10 allowing the substance 12 to escape as previously described.
Per fare in modo che le pressioni all'interno dei condotti garantiscano l'efficace entrata della sostanza 12 nel fluido principale, l'unità 11 comprende altresì, prima o dopo la valvola 10, un regolatore 13 di pressione avente la funzione di regolare la pressione della sostanza 12 in ingresso nel condotto interno della lancia; allo stesso modo anche in ingresso 3 è previsto un associato regolatore di pressione 14 che regola la pressione dell'acqua in ingresso nel condotto interno della lancia. To ensure that the pressures inside the ducts ensure the effective entry of the substance 12 into the main fluid, the unit 11 also comprises, before or after the valve 10, a pressure regulator 13 having the function of regulating the pressure. substance 12 entering the internal duct of the lance; in the same way, an associated pressure regulator 14 is also provided at the inlet 3, which regulates the pressure of the water entering the internal duct of the lance.
La ottimale registrazione dei parametri di pressione tra i due fluidi consente di definire in maniera precisa il rapporto di miscelazione acqua/sostanza desiderato. The optimal recording of the pressure parameters between the two fluids allows you to precisely define the desired water / substance mixing ratio.
Nell'esempio si descrive una lancia con valvola 10 unidirezionale comandata in apertura da un organo di comando; tuttavia la valvola 10 potrà essere azionata anche con comando separato, quale un pulsante o un secondo leverismo adiacente al primo descritto. The example describes a lance with a one-way valve 10 commanded to open by a control member; however the valve 10 can also be operated with a separate control, such as a button or a second lever mechanism adjacent to the first described one.
Ancora, detta valvola 10 unidirezionale è agganciabile sulla impugnatura, regolando così il canale di immissione collegato a sua volta in derivazione con il condotto interno, che raggiungerà il flusso d'acqua in transito a seguito della apertura del condotto per mezzo dell'organo di comando 7. Furthermore, said unidirectional valve 10 can be hooked onto the handle, thus regulating the inlet channel connected in turn with the internal duct, which will reach the flow of water in transit following the opening of the duct by means of the control element. 7.
Si descrive ora nel dettaglio l'unità 11. Unit 11 is now described in detail.
Detta unità 11 di carica è sostanzialmente un serbatoio 17 ausiliario di sostanza 12. Said charging unit 11 is substantially an auxiliary tank 17 of substance 12.
Il serbatoio è cavo all'interno e presenta conformazione cilindrica. E' suddiviso in due volumi 18, 19 mediante uno stantuffo 15 o cursore scorrevole. The tank is hollow inside and has a cylindrical shape. It is divided into two volumes 18, 19 by means of a piston 15 or sliding cursor.
Nel volume 18, quello rivolto verso la valvola 10 è alloggiata la carica di sostanza 12 da iniettare, mentre sull'altro volume 19 è contenuta aria o gas in pressione; un coperchio 16 filettato chiude il serbatoio. In the volume 18, the one facing the valve 10, the charge of substance 12 to be injected is housed, while the other volume 19 contains air or gas under pressure; a threaded lid 16 closes the tank.
L'unità 11 di carica è agganciabile all'impugnatura o corpo lancia attraverso un innesto automatico o attacco rapido o filettatura con corrispondenti guarnizioni di tenuta. The charging unit 11 can be attached to the handle or lance body by means of an automatic coupling or quick coupling or thread with corresponding sealing gaskets.
Per concludere, va detto che, una volta scaricata, l'unità 11 è riutilizzabile e riempibile di sostanza 12; il riempimento avverrà attraverso la valvola 10 di ritegno, previo distacco dell'unità 11 stessa dalla lancia 1. In alternativa e maniera del tutto equivalente potrà essere previsto una valvola 22 di ritegno laterale sul serbatoio stesso dell'unità 11. Finally, it must be said that, once unloaded, the unit 11 can be reused and filled with substance 12; the filling will take place through the check valve 10, after detaching the unit 11 itself from the lance 1. Alternatively and in a completely equivalent manner, a lateral check valve 22 may be provided on the tank of the unit 11.
Quanto sopra sarà facilitato dall'apertura della camera deN'aria in pressione, agendo su opportuna valvola di sfiato 20 e di ricarica successiva. The above will be facilitated by the opening of the pressurized air chamber, by acting on a suitable vent valve 20 and subsequent refilling.
Un manometro 21 potrà essere d'ausilio per stabilire la pressione interna alla camera 18. A pressure gauge 21 can be of help in establishing the pressure inside the chamber 18.
