Invenția, se referă la un aparat pentru stropit, destinat combaterii bolilor și dăunătorilor plantelor sau administrării de îngrășăminte în stare lichidă, utilizat în agricultură. jThe invention relates to a spraying device, intended for combating plant diseases and pests or administering liquid fertilizers, used in agriculture. j

Este cunoscută o mașină de stropit AS 14, formată dintr-un rezervor și o pompă fixată în interiorul rezervorului, care necesită în funcționare presiuni de ordinul a șase atmosfere, reglarea jetului făcându-se prin apăsare pe o pârghie a lăncii de stropit, care este prevăzută cu o singură duză de pulverizare.An AS 14 spraying machine is known, consisting of a tank and a pump fixed inside the tank, which requires pressures of the order of six atmospheres in operation, the jet being adjusted by pressing a lever on the spraying lance, which is provided with a single spray nozzle.

Se mai cunoaște un dispozitiv de stropit cu jet în evantai, care realizează transformarea unui curent dat de aer, într-un curent de aer în evantai, prin aplatizarea progresivă a secțiunilor de trecere a aerului, până la obținerea unei secțiuni de refulare convenabile, secțiune în care sunt amplasate în mod corespunzător duzele de pulverizare a lichidului.A fan jet spraying device is also known, which transforms a given air stream into a fan air stream by progressively flattening the air passage sections until a convenient discharge section is obtained, a section in which the liquid spraying nozzles are appropriately placed.

Aceste dispozitive prezintă în principal, dezavantajul că pentru obținerea unui unghi mare al jetului, necesită pe de o parte, atât forme complicate ale canalelor de conducere și dirijare a aerului, precum și lungimi mari ale secțiunilor de refulare a aerului, fapt ce face ca pentru ventilatoarele de debite mici și mijlocii să nu fie eficiente, datorită micșorării jetului și scăderii presiunii sale de penetrație în atmosferă, iar pe de altă parte necesită un număr mare de duze de pulverizare a lichidului pentru realizarea unei distribuții uniforme a picăturilor în jetul de aer, fapt ce le face inaplicabile pentru tratamentele cu volum redus și ultraredus (FR 2079514],These devices mainly have the disadvantage that in order to obtain a large jet angle, they require, on the one hand, both complicated shapes of the air guiding and directing channels, as well as long lengths of the air discharge sections, which makes them inefficient for small and medium flow fans, due to the reduction of the jet and the decrease in its penetration pressure into the atmosphere, and on the other hand, they require a large number of liquid spray nozzles to achieve a uniform distribution of droplets in the air jet, which makes them inapplicable for low and ultra-low volume treatments (FR 2079514],

Problema tehnică, pe care o rezolvă invenția, este de a aplica tratamente cu volum redus și ultraredus, printr-o distribuire uniformă a picăturilor de soluție în spațiu.The technical problem, which the invention solves, is to apply low and ultra-low volume treatments, through a uniform distribution of solution droplets in space.

Aparatul pentru stropit, conform invenției, rezolvă această problemă și înlătură dezavantajele soluțiilor cunoscute prin aceea că, conducta este prevăzută la capătul superior cu un distribuitor centrifugal de pulverizare acționat manual de o manivelă și că dispozitivul centrifugal este alcătuit din niște conducte dispuse regulat în jurul axei de simetrie, sub forma unor trapeze isoscele, având muchiile înclinate sub niște unghiuri cuprinse, între 3Q și 60° față de bază, conducte pe care sunt montate duzele de pulverizare.The spraying device, according to the invention, solves this problem and removes the disadvantages of known solutions in that the pipe is provided at the upper end with a centrifugal spray distributor manually operated by a crank and that the centrifugal device is made up of pipes regularly arranged around the axis of symmetry, in the form of isosceles trapezoids, having the edges inclined at angles ranging between 30 and 60° with respect to the base, pipes on which the spray nozzles are mounted.

Prin aplicarea invenției se obțin următoarele avantaje:By applying the invention, the following advantages are obtained:

- pulverizare avansată a lichidelor;- advanced liquid spraying;

- controlul razei de acțiune prin reglarea turației dispozitivului centrifugal;- control of the range of action by adjusting the speed of the centrifugal device;

- preț de cost scăzut.- low cost price.

Se prezintă, în continuare, un exemplu de realizare a invenției, în legătură cu figura, care reprezintă schema constructivă a aparatului de stropit.An embodiment of the invention is presented below, in connection with the figure, which represents the construction diagram of the spraying device.

Prezenta invenție propune un aparat pentru stropit, compus dintr-un rezervor 1, al cărui orificiu de alimentare este acoperit de un capac 2, o pompă manuală 3, o conductă 4 prevăzută cu un robinet, care face legătura printr-un cuplaj mobil 5 și un mecanism cu roți dințate conice 6, cu un dispozitiv centrifugal 7, de pulverizare.The present invention proposes a spraying device, composed of a tank 1, whose feed opening is covered by a lid 2, a manual pump 3, a pipe 4 equipped with a tap, which connects through a movable coupling 5 and a mechanism with bevel gears 6, with a centrifugal spraying device 7.

Dispozitivul centrifugal 7, de pulverizare este alcătuit la partea superioară din niște conducte 8 și 9, dispuse regulat în jurul axei de simetrie în grupuri de forma unor trapeze isoscele, având muchiile laterale înclinate sub niște unghiuri, de 3060°,față de baze.The centrifugal spraying device 7 is made up, at the top, of pipes 8 and 9, regularly arranged around the axis of symmetry in groups in the shape of isosceles trapezoids, with the lateral edges inclined at angles of 3060° to the bases.

Mecanismul cu roți dințate conice 6 pune în mișcare de rotație dispozitivul centrifugal 7, cu ajutorul unei manivele 11.The bevel gear mechanism 6 sets the centrifugal device 7 in rotational motion, using a crank 11.

Claims

RO 117136 B

On the pipes 8 and 9 of the centrifugal device 7 are regularly arranged nozzles 10, necessary for spraying solutions for combating plant pest diseases or for carrying out treatments. Nozzles 10 can have various shapes from simple holes or nozzles to capsules and dispersion heads. Instead of the mechanism with 50 conical gears 6, other technical solutions based on transmission belts or chains can be used.

In other constructive variants, the centrifugal device 7 has the upper part made up of semicircular pipes or is in the form of truncated or hemispherical boxes centered on the axis of symmetry, having single or even double walls, when the liquid circulates through the space between the walls. ⁵⁵

The nozzles 10 are regularly arranged at the top, having various shapes, from simple holes or nozzles to the capsules and dispersion heads known in the current state of the art.

A simple case is the branched centrifugal device, with nozzles regularly arranged at the ends of two or more pipes that form 60° angles between 30 and 180°.

To put the device into operation, proceed as follows:

- unscrew the cap 2 and pour liquid into the tank 1 until it is filled to about two-thirds of its volume;

- screw the lid 2 until it is securely sealed, close the 65 valve on the pipe 4 and put the tank 1 under pressure of 3....6 at using the manually operated pump 3.

The device, thus prepared, is transported to the work area where its contents are sprayed, by opening the valve on the exhaust pipe 4 and operating the crank 11 to obtain speeds of the centrifugal device 7 of 70,400...800 rpm.

Due to centrifugal and pressure forces, the liquid is sprayed through the nozzles 10 in the form of fine droplets evenly distributed in space.

Adjusting the range of action of the device is done conveniently by changing the speed of the centrifugal device. Depending on the size, the device is moved either by carrying it on the back with the help of straps, or by placing it on the platform of a means of transport.

To switch the technical means to mechanized operation, it is necessary that it be equipped with a thermal or electric motor to operate both the centrifugal device and a compressor to pressurize the tank 1, possibly a pump for forced circulation of the liquid to the spray nozzles.
