Description

The invention relates to a device for spraying liquids and can be used for irrigating agricultural land by means of artificial sprinkling, as well as in the study of soil erosion and hydrology.

The aim of the invention is to increase the uniformity of irrigation.

Fig, 1 shows a sprinkler; Fig 2 - regulating the shutter.

The sprinkler device comprises a case of vertically mounted F-lenses and telescopically connected to annular h, pipe airi i 3, on which above the annular gaps are installed by means of a threaded connection and with the possibility of axial movement, deflector head:; г1 4 and 5 с are profiled; kidd, 1, and surfaces. The nozzle 5 has a parabolic-shaped guide surface 6 and is made with radial slits 7. A cone nozzle 8 is installed at the end of the pipe 1, with an outlet 9, the pipe 3 is installed on the tubular base 10 and the coupling I, while the device is equipped with a rotating drive, made in the form of tubular wings 12 and 13 with outlet holes And evenly spaced but on opposite sides, and

In the tubular wings x 12 and 13 there are adjustable valves, 15 shutters 15,

Coupling 1 1 is connected to supply 1, its vpy is 16,

The sprinkler works i.j ;;: - in a blowing manner.

Water from pipe 16 is supplied under pressure of 2-2.5 atm to pipes 1--3 and tubular wings 12 and 13,

The water coming out of the pipe 1, aa, is inserted into the conical 1–1 garden: at 8, passes through its outlet 9 and irrigates, mainly, the peripheral part of the round area,

E Oda, passing through the annular gap between pipes 1 and 2, is directed to the guide surface of the deflector nozzle 4 and irrigates, preferably, the middle part of the area. Coming through the annular gap between the pipe, MI 2 and 3 water

directed to the surface 6 of the nozzle 5 and irrigated: the central part of the area, while part of the water flow radially slit 7 is directed into the middle and peripheral parts of the treated area,

B ode entering the tubular wings

12 and 13, it comes out through the openings 14 in the form of an extra-irrigating area of jets, the reactive force of which causes the wings to turn. 12 and 13, and with them, the whole tubular body is rotated with nozzles 4 and 5. (The speed of the device is controlled by 1,) I adjust the shutter 15 by turning it and changing the outlet section 17 water from nozzles 4 to 5 is performed by rotating them and changing the gap between them and the ends of pipes 2 and 3 facing them,

E5bp is a masked implementation with a parabolic direction, a radial surface

cuts, as well as ensuring vrap1eni pipes with nozzles increases the uniformity of water,

The use of the proposed invention makes it possible to obtain high-quality and uniform irrigation of the cultivated area, as well as to increase the reliability of scientific research in the field ;; erosion and hydro. of soils.
