Abstract

The invention relates to irrigation of agricultural crops by sprinkling and can be used in difficult relief conditions. The purpose of the invention is to improve the quality of irrigation by ensuring uniform distribution of water over the irrigated area. The system contains self-oscillating sprinklers, equipped at the entrances with station 5 flow regulators. During the irrigation process, as the water cavities of the hydropneumatic accumulators 7 are filled, valve 15 is activated and a cycle of rain splash over the irrigated area occurs. The use of flow stabilizers makes it possible to create identical conditions for filling the hydro-pneumatic accumulators of all sprinklers, regardless of their hydraulic and geodetic working conditions. 2 Il. ;

The invention seeks to irrigate agricultural crops with sprinkling and can be used in difficult relief conditions.

The purpose of the invention is to improve the quality of irrigation by ensuring uniform distribution of water throughout the irrigated area.

FIG. I depicts the proposed | Q system, a general view; Fig. 2 is a diagram of a self-oscillating sprinkler.

The system contains pressure source 1, distribution 2, irrigation 55 3 and supply A pipelines. Irrigation pipelines 3 are connected via flow regulators 5 and pulse sprinklers 6 of self-oscillating action, 6, Flow stabilizers provide flow

Pulse sprinkler of self-oscillating action contains pneumohydroaccumulator 7, the body of which is equipped with perforated roof 8, separating diaphragm 9 fixed between 30 flanges of the body and krpnka 10. The output of flow regulator 5 through tube 11 communicates with the internal cavity of the valve J2, to the body of which is mounted through a junction of the adapter 13, a sprinkler 13, Adapter 3 with a seat of a piston valve 15 including a spring

The system works as follows

Water from a source of pressure I is fed to a distribution pipe.

water 2 and irrigation pipelines 3, then through the supply pipe A, flow rate stabilizer 5 into the water cavities of the pneumatic accumulators of the sprinklers. As the water cavity is filled, the diaphragm 9 moves to the perforated arch 8 of the Duzs aircar.

When the total volume of the flasher is set, the valve moves away from the saddle and opens abruptly, since the opening force Hai increases due to the pressure on the back plane of the valve 15. When the valve is opened, the water cavity of the pneumogram accumulator through the annular gap between the valve body 12 and the hydraulic cylinder 17 and adapter I3 communicates with the sprinkler. Rain is spilling over the irrigated area. At the end of the splash, the valve closes, the diaphragm moves to a depth of 10, the Sprinkler returns to its original state. Then the watering cycle is repeated. All sprinklers of the system work in the same way.

The uniformity of irrigation over the irrigated area is ensured by the presence of flow stabilizers at the sprinkler inlets.
