The sprinkler nozzle apparatus

 

(57) Abstract:

Use: agricultural engineering, specifically in the construction of the sprinkler apparatus. The inventive nozzle sprinkler apparatus includes a hollow hexagonal building 1, bar 2, the screw-jet divider 3, the deflector plate 5 made of carbon steel, and the water outlet nozzle 4 in the form of a ring made of brass or plastic, with a hole in the steel part of the body 1 has the shape of a cylindrical Cup, the bottom of which is made coaxial hole smaller than the cylinder diameter of the annular ledge, and a nozzle 4 inside has the shape of a truncated cone, rolling in the cylinder, the length of which is equal to 1 - 3 of its diameter. 1 C.p. f-crystals, 12 ill.

The invention relates to agriculture, in particular for irrigation technique, and can be used in all types of rooms and sredneshirotnykh and delestrogen sprinkler devices.

Known nozzles sredneshirotnykh sprinkler devices N 1, 2, 3, 4 and delestrange installed, for example by sprinkling machines, circular steps "Frigate" and valley (USA), comprising a hexahedral housing with external thread on one end, which he screwed into the boiled to one of the edges of the other end of the housing, and, accordingly, the divider in the form of a screw, twisted pair into the threaded hole at the free end of the strap, with the pointed end (arrow), located approximately on the centerline of the nozzle at a distance of several nozzle diameters from it into the water cutoff (Reference mechanization irrigation, Ed. Stay B. T. M. Kolos", 1979, similar).

Nozzle-analogues have some significant drawbacks. First, the chassis is made from expensive and scarce material alloy of copper and tin, and the bar divider stainless steel. Despite the fact that the nozzles do to the apparatus sprinkling machines "Frigate" for 20 years, the technology of their connection has not given sufficient operational reliability: extensive survey showed that the vast amount of sprinkling machines machines work with attachments without slats, and therefore without dividers jets designed to raspushenny jets and the formation of rain all the way from the device to the most far it drops. Such devices work as the hoses, releasing the rain in the form of large (up to 5 mm) drops only in the far distance (15 to 25 m). The nozzle without straps and dividers are the cause of active destruction of the erosion of the soil structure, the speed of allow case and strap attachments are almost impossible to repair in the conditions of the economy: their connection requires welding on the basis of the additive is borax and the highest skill of the welder. For this reason, the economy never change nozzles, and the purchase in whole apparatus expensive because of their high cost and difficult because of their deficiency. Therefore, the units operate without straps and dividers jets of water, making the rain invalid intensity.

Known nozzles so-called "Universal sredneshirotnykh sprinkler apparatus including the same corpus with internal water final calibrated orifice-nozzle, strap screw on the end and welded to a strap from the bottom plate deflector, perceiving at an acute angle hit the water jet emitted by a cylindrical nozzle with a speed of 10 to 30 m/s, which makes thin-film jet with the formation in the atmosphere atomized rain falling on a large irrigation area, with a reduced environmental harm to the earth in comparison with analogues (see application N 9/4020136 priority from 16.06.94, prototype).

And nozzle prototype has the same drawbacks as similar: expensive non-ferrous metal body and the unreliability of its connection with the steel strip carrying the deflector and the adjusting screw installation with the horizon and the same premenopausally in conditions.

The purpose of the invention, the reduction in stand is undertaken goal is achieved by such components of the nozzle, as the case, strap, screw divider or screw tilt adjusting plate of the deflector and the deflector are made of carbon steel, which is easily welded conventional welding, and the inner part of his body into the water nozzle is manufactured in the form of a ring whose length equals the body, brass or plastic, with a hole in the steel casing in the form of a cylindrical Cup, the bottom of which (output stream) is made coaxial annular hole-ledge with a smaller diameter, and an annular nozzle inserted into the housing, has the same shape and size on the outside, and inside decreasing in the course of the water jet cone followed by a cylinder whose length in proportion to its diameter is 1 3.

In Fig. 1 schematically shows a nozzle for serial sprinkler apparatus in the context of a longitudinal axis of the water outlet hole; Fig.2 is a view along a-a of Fig.1; Fig.3 nozzle universal sredneseriynoe sprinkler apparatus in the context of a longitudinal axis of its water outlet hole; Fig.4 is the same, the view along B-B of Fig.3; Fig.5 view of the nozzle universal sprinkler apparatus from above, Fig.3; Fig.6 and 7 scheme of work the nozzle in Fig.1 on serial Doge is integrated sredneseriynoe sprinkling apparatus; in Fig.10 and 11 in position universal apparatus, inverted 180ofrom the standard; Fig.12 is the same as in Fig.8 11, top view.

The sprinkler nozzle apparatus includes a housing 1, bar 2, a screw 3, the deflector 5 from carbon steel and additionally, inside the housing, insert the nozzle 4 is made of brass or plastic.

Works nozzle by known technologies. For example, serial sprinkler apparatus (Fig.1, 2 and 6), the water enters the conical part of the nozzle 4 from the side of the large diameter is compressed in its cylindrical part, in which turbulent motion becomes laminar and holes are emitted in the form of an infinite cylinder at an angle of about 30oin the atmosphere, and, colliding with the sharp end of the screw-divider 3, spray lightly fluffed in the form of vertical sails rain D1 (Fig.7), the width of R1 falls on irrigated the field surface. During rotation of the apparatus by pushing 2-4othe field is formed political circle, and when the motion of the vehicle with a sprinkling machine washed band. On the universal machine the machine can operate and described nozzle (Fig.1, 2) with plate deflector (Fig.3, 4 and 5), as indicated in Fig.8 12. Water - In enters the conical cylinder is struck at an acute angle at the end portion in the edge of the baffle plate 5, which is in the form of a thin film at an angle 0 +10oto the horizon with a high speed of 10 to 30 m/s is discharged into the atmosphere, connecting with the which turns into a sector atomized rain D2and D3width W2and approximately equal to W3with less intensity than in Fig.6, 7 and best environmental properties that can increase yield and to provide a positive economic result of the amount of water, energy resources and investments.

It is obvious that the proposed solution will find wide use. It will lead many tens of thousands of sprinkler devices in an environmentally safe condition effects on irrigated land, more economically advantageous because it allows the earth to give and in the beginning, and the prospect of higher yields. And, in addition, its industrial use, it is advantageous and guarantees higher reliability, durability and the ability to carry out repairs in farms. 2 4 6 8
