Description

“IRRORATRICE AD ACCUMULO D’ARIA IN PRESSIONE” "SPRAYER WITH ACCUMULATION OF PRESSURE AIR"

L’invenzione proposta è una irroratrice portatile per fitofarmaci ovvero altri liquidi da nebulizzare da usare in agricoltura . Come tutte le irroratrici di piccole o medie dimensioni può anche essere vantaggiosamente impiegata nelle disinfestazioni civili. The proposed invention is a portable sprayer for pesticides or other liquids to be sprayed for use in agriculture. Like all small or medium-sized sprayers, it can also be advantageously used in civil disinfestation.

Le irroratrici portatili reperibili attualmente sul mercato funzionano in uno dei seguenti tre modi: Portable sprayers currently on the market work in one of three ways:

* manualmente (la pressione necessaria al funzionamento viene fornita tramite una pompa a mano), * manually (the pressure required for operation is supplied by a hand pump),

* elettricamente (la pressione viene fornita da una pompa mossa da motorino elettrico che viene alimentato con una batteria ricaricabile) * electrically (the pressure is supplied by a pump driven by an electric motor which is powered by a rechargeable battery)

* con motore a scoppio (la pressione viene fornita da una pompa fatta funzionare da un motore a scoppio). * with internal combustion engine (the pressure is supplied by a pump operated by an internal combustion engine).

La irroratrice azionata manualmente ha il suo limite nella scomodila di dovere dare ia pressione di esercizio alia macchina attraverso appunto una azione manuale, la qual cosa la rende poco comoda per lavori di media o grande entità. The manually operated sprayer has its limit in the inconvenience of having to give the operating pressure to the machine through a manual action, which makes it not very convenient for medium or large-scale jobs.

La irroratrice azionata elettricamente pur conservando una buona praticità di uso, necessita di una ricarica delia batteria che impiega diverse ore. The electrically operated sprayer while maintaining a good practicality of use, requires a battery recharge which takes several hours.

La irroratrice azionata da un motore a scoppio è sicuramente ia più potente ma comporta iJ trasporto appunto di un motore a scoppio e del carburante necessario al suo funzionamento e comporla anche una manutenzione senza dubbio maggiore di quella necessaria per le pompe manuali o elettriche. The sprayer driven by an internal combustion engine is certainly the most powerful but involves the transport of an internal combustion engine and the fuel necessary for its operation and also requires maintenance without doubt greater than that required for manual or electric pumps.

Scopo della presente invenzione è permettere di svolgere la irrorazione senza pompare manualmente, senza ['utilizzo di motore elettrico e dunque di una batteria da ricaricare, senza Lutili zzo ed il trasporto di un motore a scoppio e del carburante ad esso necessario. The object of the present invention is to allow spraying to be carried out without pumping manually, without using an electric motor and therefore a battery to be recharged, without using it and transporting an internal combustion engine and the fuel necessary for it.

La irroratrice qui presentata consiste infatti, nelle sue pani essenziali, di un serbatoio adatto per l’accumulo di aria compressa, un impianto carico c distribuzione dell’aria, un serbatoio per il liquido da irrorare, un impianto di carico e di rilascio del liquido, cui è connessa la lancia irroratrice attraverso apposito tubo dì gomma. Il congegno può essere montato su un carrello. In fact, the sprayer presented here consists, in its essential bases, of a tank suitable for the accumulation of compressed air, a loading system with air distribution, a tank for the liquid to be sprayed, a system for loading and releasing the liquid. , to which the spray lance is connected through a suitable rubber tube. The device can be mounted on a trolley.

La soluzione tecnica proposta dall’ inventore è accumulare la riserva di aria necessaria al lavoro di irrorazione nei serbatoio di aria compressa tramite un normale compressore d'aria (anche i modelli più economici in commercio servono benissimo lo scopo) in modo da svolgere poi rimerà operazione di irrorazione fino ad esaurimento del fitofarmaco senza pause. Terminala l’operazione del carico dell’aria nel serbatoio, che impiega qualche minuto, il compressore viene staccato dalla irroratrice che viene resa autonoma. The technical solution proposed by the inventor is to accumulate the reserve of air necessary for the spraying work in the compressed air tank through a normal air compressor (even the cheapest models on the market serve the purpose very well) in order to carry out the operation again. of spraying until exhaustion of the pesticide without pauses. Once the operation of loading the air into the tank is completed, which takes a few minutes, the compressor is disconnected from the sprayer which is made autonomous.

il fitofarmaco viene invece caricalo nel Lappo sito serbatoio per i liquidi. Il serbatoio dei liquidi è dotato di un bocchettone che permette la connessione ad un normale rubinetto da giardino attraverso un tubo di quelli comunemente usati per innaffiare, con attacchi rapidi a tenuta. In questa maniera viene introdotta nella macchina l’acqua necessaria alla diluizione del fitofarmaco. Un conta-litri posto all’ingresso deirimpianto di carico permette di introdurre con precisione l<'>esatta quantità d<’>acqua necessaria, the pesticide is instead loaded into the Lappo reservoir site for liquids. The liquid tank is equipped with a union that allows the connection to a normal garden tap through a hose of those commonly used for watering, with quick-release couplings. In this way, the water needed to dilute the pesticide is introduced into the machine. A liter-counter placed at the entrance to the loading system allows you to accurately introduce the exact amount of water needed,

L’acqua di diluizione, nel caricare il serbatoio del fitofarmaco, attraversa un serbatoio di miscelazione del farmaco, dotato al suo interno di clementi elicoidali che favoriscono appunto la miscelazione, nel quale si sarà preventivamente immesso il fitofarmaco nella sua forma in polvere o concentrata. In tal modo la sostanza da irrorare è ben diluita e pronta all’uso. The dilution water, when loading the pesticide tank, passes through a drug mixing tank, equipped inside with helical elements that favor mixing, into which the pesticide in its powder or concentrated form will be previously introduced. In this way the substance to be sprayed is well diluted and ready for use.

Terminate le operazioni di carico dell’aria e del liquido, attraverso una apposita valvola si immette l’aria compressa nell’ impianto che connette il serbatoio dell’aria con quello dei liquidi, mettendo cosi la macchina in pressione. La pressione di spinta del liquido viene tenuta costante durante tutto l’utilizzo attraverso un apposito regolatore di pressione, che garantisce la giusta pressione di esercizio fino al completamento del lavoro. Once the air and liquid loading operations have been completed, through a special valve the compressed air is introduced into the system that connects the air tank with that of liquids, thus putting the machine under pressure. The thrust pressure of the liquid is kept constant throughout use through a special pressure regulator, which guarantees the right operating pressure until the work is completed.

Π serbatoio del liquido è dotato al suo interno di un polmone di gomma che ha il duplice compito di tenere separato il liquido dall’aria compressa e di agevolare il completo svuotamento del serbatoio. The liquid tank is equipped with a rubber buffer inside which has the dual task of keeping the liquid separate from the compressed air and facilitating the complete emptying of the tank.

L’aria compressa residua dopo il lavoro di irrorazione fornisce pressione per la pulizia della macchina, e degli augelli di spruzzo prima del nuovo utilizzo. The residual compressed air after the spraying work provides pressure for cleaning the machine, and the spray nozzles before using it again.
