The disadvantages of the injector drip irrigation is a low quality irrigation in root horizon.

The essence of the claimed invention.

The challenge aimed declare invented the e, selective supply of irrigation water to the roots of trees or plants.

The technical result improved quality of irrigation.

This technical result is achieved by the fact that in the known injector for drip irrigation systems, including the outlet, a porous body with a plug at the lower end and mounted them in a replaceable porous element according to the invention, a replaceable porous element made in the form of the cylinder, paired diametrically planes on the cylindrical surface of each executed part of the groove, forming a vertically-oriented channels in the plane of the connector and screw grooves in the mating parts of the cylinder, the steps of the spiral grooves are not multiples of each other, and an outlet provided with a float valve located therein above the pressure damping; the cap on the end the porous housing is fitted with a cumulative camera.

By performing a replaceable porous element in the form of the cylinder with helical grooves on the surface is achieved by the above technical result.

The invention is illustrated by drawings.

Information confirming the possibility of implementing the claimed invention are as follows.

Injector for drip irrigation systems includes the outlet 1, the porous body 2 with the cover 3 at the lower end and mounted them in a replaceable porous element 4.

Outlet 1 consists of a cover 5 to the outlet 6 and the outlet for air and supporting frame 7. The cover 5 with the supporting frame 7 are mutually connected by a threaded section 8. Outlet 1 is equipped with a float valve 9. The valve 9 has a shut-off needle 10 and the supporting elements 11 on its bottom part 12. Shut-off needle 10 has the capability of interfacing with a conical socket 13. The float valve is mounted above the chamber 14 of the damping of the pressure of the outlet 1.

The porous body 2 is provided longline posted by radially oriented lugs 15, 16 and 17. The porous body 2 is connected with the lower part of the supporting frame 7 and the cover 3 at its lower end.

Cover 3 at the end of the porous cor the USA 2 has a cumulative camera 18.

Replaceable porous element 4 is made in the form of the cylinder 19 and 20. On the cylindrical surface of each part 19 (20) is made of the grooves 21. The grooves 21 when the coupling parts of the cylinder 19 and 20 form the channels 22 and 23 in the plane of the connector. On the cylindrical surface portions 19 and 20 is screw grooves 24 and 25. In the mating parts 19 and 20 replaceable porous element 4 helical grooves 24 and 25 are not multiples of each other.

Injector for drip irrigation systems is as follows.

Before working injector on irrigated area check its completeness and correctness of the Assembly. Depending on the type of root systems of tree plantations or agricultural plants in the porous body 2 is placed a removable porous elements 4 with different costs of irrigation water. For this purpose, the cover 5 sbencivu with the supporting frame 7. From the cavity of the supporting frame 7 remove the float valve 9. Next, the bottom end of the housing 2 disassemble the cover 3. Ramrod push replaceable porous element 4 from the housing 2. Next, the operator visually evaluates the condition of the parts 19 and 20 of the element 4 and is a couple in accordance with the normal flow of the water injector. The injector Assembly is performed in the opposite order.

On the pre-wetted area of the hull 2 with the lugs 15, 16 and 17 of the injector is implanted into the layer of soil so the image is m, to cover 5 spoke over the top layer of soil at 1-2 cm Inlet 6 on the cover 5 connect the flexible hose to the nipple of the water distribution network of drip irrigation system.

When submitting pre-cleaned of sediment and mineral Sora irrigation water in the inlet opening 6 in the cover 5 jet of water from the cone socket 13, extending and extinguishing speed, gets on the edge of the shut-off needle 10 and flows down on the surface of the float valve 9, filling the cavity of the supporting frame 7 and the camera 14 damping of the pressure of the outlet 1. The support elements 11 on the bottom part 12 of the float valve 9 is held with a gap above the chamber 14 of the damping pressure. The flow of water gently flowing down into the chamber 14, and vertically-oriented channels 23 and 22 replaceable porous element 4 is fed into the collection chamber 18, providing access water across the surface of the porous body 2.

When filled with water the total volume of the injector float valve 9 POPs up over the camera 14 damping pressure. Shut-off needle 10 of the valve 9 closes off the living section of the conical socket 13. Outlet port “a” connects the cavity of the supporting frame 7 with the atmosphere, the bypass air and the constant pressure on the water. The water from the channels 22 and 23 and the helical grooves 24 and 25 of the element 4 through the porous body 2 enters the root layer of soil. Inouye grooves 24 and 25 provide damping the flow of water and its distribution with the specified flow rate. It provides high quality drip irrigation.
