Abstract

The invention can be used for irrigation of orchards and agricultural crops and for spraying liquids in various industries. The purpose of the invention is to provide opportunities for self-regulation of consumption and increase reliability in the work by reducing clogging. To this end, the nozzle is equipped with a curl stop. The swirler is installed with the possibility of axial movement and rotation and is made of elastic material. Swirler tabs have a triangular cross section. The nozzle is also provided with a rigidly connected with a swirl deflector located at the exit of the nozzle. The distance from the lower plane of the swirl to the cross section of the deflector, equal to the cross section of the nozzle, is chosen equal to the distance from the limiter to the exit plane of the nozzle. 2 hp ff, 1 ill.

Description

(L

The invention relates to agriculture and can be used for irrigation of orchards, vineyards and other agricultural crops and for spraying liquids in various industries.

The aim of the invention is to provide the possibility of self-regulation of the flow rate and an increase in operational reliability due to a decrease in the clogging.

The drawing shows a nozzle, a general view.

The nozzle includes a housing 1 with nozzles 2 and a Swirl chamber 3 and a swirler 4 with screw lugs 5 mounted in the swirl chamber 3 with the possibility of axial movement.

The nozzle is also equipped with a limiter 6 stroke swirl 4 installed in the chamber 3 of the vortex.

The swirler 4 is rotatably mounted and made of an elastic material, for example rubber, and the protrusions

5 swirl 4 are made with a triangular cross section.

The nozzle, in addition, is provided with a rigidly connected with the swirler 4 and the deflector 7, located at the exit of the nozzle 2.

The distance from the lower plane of the swirler 4 to the cross section of the deflector 7, equal to the cross section of the nozzle 2, is chosen to be equal to the distance from the limiter 6 to the output plane of the nozzle 2.

The nozzle works as follows.

Irrigation water (sprayed liquid) is fed into the chamber 3 swirls, lifts the swirler 4 above the stop 6, and passes between the screw lugs 5. At the same time, the swirler 4 is not pressed tightly against the housing 1, the water turns it due to the reactive force arising during the flow of screw protrusions 5. Since the screw protrusions 5 have a triangular cross-section, their sharp outer edges scrape off the surface of the chamber 3 swirling deposits (if any).

the latter are discharged by the flow of water through the nozzle 2 to the outside. As the pressure in the irrigation network grows, the swirler 4 presses more and more tightly to the chamber surface 3 vortexes, the rotation stops, the screw lugs 5 are compressed and pressed into the swirler 4 (due to the triangular section, the screw lugs 5 behave more elastic than the central part of the swirl 4). The flow area between the swirler 4 and the housing 1 is reduced, and the greater the pressure, the more compressed the swirler 4, the smaller the flow area, thus maintaining flow-independent flow. Irrigation water jets, formed by screw protrusions 5, come together as they pass through nozzle 2, are sprayed, and the resulting water mist irrigates the plants. After the water supply is shut off, the screw lugs 5 are unclenched and the swirler 4 is separated from the chamber 3 by swirling. Due to the triangular cross section of the screw protrusions 5, the swirler 4 contacts with the chamber 3 swirls not along the surface, but along the lines of the vertices, which prevents the swirler 4 from sticking and subsequent overgrowing of the culvert sections. Under its own weight, swirl 4 descends in the chamber 3 swirls down to limiter 6. The elasticity of swirl 4 is sufficient so that when assembling the nozzle with a small force, swirl 4 into the chamber 3 swirls through restrictor 6, but back through the stopper 5 under its own weight, swirl 4 falls out.

The nozzle works in a similar way, the swirler 4 of which is provided with a deflector 7. The difference is that the deflector 7 takes part in the forming

fog, improving spray quality and increasing the irrigation radius. In addition, after turning off the water supply, the swirler 4 with the deflector 7 is lowered under the action of its own weight, and the nozzle simultaneously locks on both sides: due to the equal vertical dimensions up to the shut-off sections, the edge of the swirler 4 joins the stopper 6, and the deflector 7 blocks the nozzle 2. Thus Thus, penetration of small animals into the nozzle, litter ingress and evaporation of the remaining water in the system with subsequent precipitation are prevented.
