Sprayer with cyclone

The invention relates to agricultural machinery, in particular to sprayers and can be used for protection of vineyards against pests and diseases.Sprayer with cyclone comprises a frame on wheels, on which are mounted a tank for working fluid, connected in series to a pump with cardan gear, a pressure regulator and two pipelines (16) with atomizers (17). The sprayer also contains a centrifugal fan (5), to which are connected two curved pipelines for air circulation, each composed of horizontal and vertical (7) rods. To the vertical rod (7) is fixed the pipeline (16) with atomizers (17). The sprayer additionally comprises two cyclones (8) with suction confusors (9). The cyclones (8) are connected to the centrifugal fan (5) and provided with a main accumulator (10) with a filter (11) for the captured working fluid, which is connected to the tank through an ejector for the transfer of the captured working fluid into the said tank. In the lower part of confusors (9) are installed two secondary accumulators (18) for the captured working fluid, connected to the main accumulator (10). The pipelines (16) are made with the possibility of installing the atomizers (17) opposite to the center of confusors (9) by means of two rotary arms (20) with hydraulic cylinders (21).The result consists in spraying with working fluid in a sufficient quantity two rows of vineyards concomitantly, in reducing soil pollution with toxic chemicals and conserving the working fluid used for plant treatment. Invenţia se referă la tehnica agricolă, în special la maşinile de stropit, şi poate fi utilizată pentru protecţia plantaţiilor de viţă-de-vie contra dăunătorilor şi bolilor.Maşina de stropit cu ciclon conţine un cadru pe roţi, pe care sunt montate un rezervor pentru lichidul de lucru, unit consecutiv cu o pompă cu transmisie cardanică, regulator de presiune şi două conducte (16) cu pulverizatoare (17). Maşina de stropit mai conţine un ventilator centrifug (5), la care sunt unite două conducte cotite pentru refularea aerului, alcătuite fiecare dintr-un braţ orizontal şi unul vertical (7). La braţul vertical (7) este fixată conducta (16) cu pulverizatoarele (17). Maşina de stropit conţine suplimentar două cicloane (8) cu confuzoare de aspiraţie (9). Cicloanele (8) sunt unite cu ventilatorul centrifug (5) şi dotate cu un acumulator principal (10) cu filtru (11) pentru lichidul de lucru captat, care este unit cu rezervorul printr-un ejector pentru transportarea lichidului de lucru captat în
