Description

The invention relates to agriculture and is intended for irrigation of crops.

The purpose of the invention is improving the quality of irrigation and uniformity of water distribution along the front of sprinkling.

The drawing shows a schematic diagram of a sprinkler.

The sprinkler system contains a trolley 2 moving along a rail 1, on which a mast 3 is mounted. Irrigation pipelines 5 are cantilevered to the latter by means of stiffeners and stretch marks 4 with the possibility of changing the height position of each pipeline separately using mechanisms - winches 6. Towards irrigation pipelines 5 through the nozzles with valves 7 for regulating the water pressure, a flexible pipe 8. is connected through which water is pumped 9. The flexible pipe 8 is suspended in a spiral form on a cable 10 fixed to the support racks 11 installed at the ends of the rail

1. A filter 12 is installed between the pump 9 and the flexible pipe 8 to purify water from mechanical impurities. Irrigation pipes 5 are assembled from a set of pipes with diameters of 38-19 mm. in which holes 13 directed downwards are made at distances of 10-15 cm from one another with a diameter

- 2 mm.

With this distance between the holes 13 and their diameter, a multivariate irrigation is provided by sprinkling of crops with different row spacings - 7 cm or more.

The ends of the irrigation pipelines 5 are lowered down by the amount of water pressure loss in them to ensure the same pressure and water supply by all openings 13. At the ends of the irrigation pipes, one hole 14 with a diameter of 1.5 mm is made, directed upward, forming a fountain. At the holes 14 fixed measuring rulers 15 for measuring pressure. The trolley is equipped with a movement mechanism made in the form of an electric drive with a reducer 16, on the axis of which a block (not shown) is installed that moves the cable 17, the ends of which are fixed at the ends of the trolley 2. The cable passes through the freely rotating block 18 in the opposite part of the path from the reducer block 19 control irrigation and imparting reciprocal movement in a predetermined range, for which limiters 20 are installed on rail tracks

Started sprinkler ^m flushes follows.

With pump 9, water is supplied through filter 12 to flexible pipe 8 and through valves 7 to irrigation pipelines 5. The water pressure in irrigation pipelines 5 is regulated by valves 7 at the level of 1–3 m water column. With such a pressure of water in the size of the holes in the pipelines of 1.5 mm, the formation of droplets of not more than 1.0 mm and their free fall on the soil is ensured.

The installation is moved along the rail 1 by means of a cable 17 thrown over a block with a groove in which the cable is jammed. The gear 16 has several speeds of rotation, so you can change the speed of movement of the sprinkler. The movement of the trolley 2 is carried out in automatic mode by the control unit 19 and special stops 20. When they reach which the trolley stops and returns back to the first stop, which also stops and goes back to the second stop.

In the proposed irrigation plant, water is supplied to the plants by concentrated current through pipelines located directly above the plants and freely poured onto the plants from the openings in the form of drops directed downward.

The size of the drops in all parts of the irrigated area is the same, since the size is determined by the diameter of the holes and the pressure of the water at these irrigation holes. Throughout the irrigation area, both are the same. Plants are not damaged, the soil structure is not destroyed.

Irrigation rates can be set large, as drizzling rain does not produce runoff. There is no rain cover in the irrigation area, since each hole serves its irrigation strip 57 cm wide

Claims (2)

Claim 1. Sprinkler installation, including irrigation pipes with water outlets, cantilever mounted on the cart, and a device for raising and lowering them, characterized in that. what. in order to improve the quality of irrigation and uniform distribution of water along the sprinkling front, irrigation pipelines are mounted on a trolley with a downward slope to compensate for head loss along the length of the pipeline. 2. Installation under item 1, characterized in that the holes are located with an interval of 100 - 150 mm and have a diameter of 1-2 mm.
