The invention relates to agriculture and can be used for irrigation when the soil moisture drip method preferably trees.

Known dropper comprising a housing with inlet and outlet ports and a fixed float valve element included in the input pipe, in which the purpose of self-cleaning drip and simplify its design case and the float is made in the form of a concentric set of cones, while the float is provided with a second locking element within the outlet, and has on the surface a spiral ledge; to regulate flow second shut-off element is made removable (SU inventor's certificate No. 704540, MCL2A 01 G 25/02. Dropper / Hijabi (USSR).- Application No. 2630295/30-15; Claimed 19.06.1978; Publ. 25.12.1979, bull. No. 47 // Opening. Of the invention. - 1979. No. 47).

The disadvantages of this dropper is low reliability. This is because the silt particles settle out of the water in the annular chamber between the bottom cover 7 and the ring stops 8 for the float 3. Filling with silt annular groove between the cover 7 and lugs 8 leads to misalignment of the float body 1. The drip stops working. Drip supplies water only to the surface of irrigated land.

Also known drip outlet including a housing with two connecting hole cameras, the inlet and outlet openings and a float valve, located in the upper chamber, in order to improve the reliability of the outlet comes with a second float valve installed in the lower chamber, while both valves are made double-acting; with a view to expanding the range of operating pressures for a given flow rate through the holes in the cameras mounted adjustable inserts (SU inventor's certificate No. 858670, MCL3A 01 G 25/02. Drip outlet / Ashkenazi, Genmukan, Innentaschen and others (USSR). - Application No. 2441080/30-15; Claimed 05.01.1977; Published 30.08.1981, bull. No. 32 // Opening. The invention. - 1981 - №32).

The disadvantages of this droplet discharge are high demands on the purity of the water and simply installed vertically. A slight misalignment of the housing outlet leads to retarded to the provisions of the float valves 5 and 6. This reduces the operational reliability of the water outlet.

The closest analogue to the stated object is a device for drip irrigation, comprising a housing with an inlet and outlet and located in it float regulating element, in order to improve the uniformity of the irrigation device is provided with an additional float regulatory element located within the core and having a T-shaped squoze the hole and telescopic suction tube connecting the said inlet opening to the outlet opening of the housing (SU inventor's certificate No. 782766, MCL3A 01 G 25/02. Device for drip irrigation / Wthdrawal (USSR). - Application No. 2765876/30-15; Claimed 15.05.1979; Published 30.11.1980, bull. No. 44 // Open. Of the invention. No. 44).

The disadvantages of this device adopted us as naiblizhajshee analogue include design complexity and low reliability. Despite the fact that it is provided with an additional float regulating element, suspended solids and silt particles are not eliminated from the body. As they accumulate in the bottom part of the housing 2 vodozapornyh valve 7 closes the inlet 3 and the device stops working. This device is not intended for water supply in the root horizon.

The closest analogue to the stated object is injector for drip irrigation, including outlet and a porous body, in which the purpose of providing a controlled supply of water, improve the reliability of irrigation and simplify the design, it is equipped with a pressure regulator, made in the form of a replaceable porous element (SU inventor's certificate No. 812237. Ml3A 01 G 25/02. Injector for drip irrigation / Vchurin, Huseyin, Nepitani (USSR). - Application No. 2773423/30-15; Claimed 31.05.1979; Publ. 15.03.1981, bull. No. 10 // Open. Of the invention. - 1981. - what is 10).

The disadvantages of this injector is that the water to the roots of plants fed unevenly. Described injector does not take into account the structure of the skeletal and sucking the roots of trees. In the presence of the core roots of water must be supplied differentially: with increasing depth portions of the feedwater is expected to increase, despite the fact that the density of soil in soil, arable horizon is less than the density of the soil in the subsurface horizon.

The essence of the claimed invention is as follows.

Task to be solved by the claimed invention is directed, enhanced operational reliability of soil moisture.

The technical result - the more uniform distribution of precipitation during the irrigation, simplifying the design, reducing direct costs to operate the system with sub-surface irrigation.

This technical result is achieved by the fact that in the known injector for drip irrigation, comprising a porous body with an inlet and outlet and outlet located therein float regulating element with vodozapornyh valve in its upper part, according to the invention in the upper part of the outlet float above the regulatory element is made valves for air release and in the porous body parallel what about the outlet in the edges of pacotaco made floating holes.

Due to the fact that at the bottom and the edges of pacotaco porous body is floating holes, irrigation water at the expiration of fond evenly at different depth of the soil in accordance with the distribution of the roots of trees, achieved the specified technical result.

The invention is illustrated by drawings.

Figure 1 shows the injector for drip irrigation, type in the plan.

Figure 3 - cross section b-B figure 1 is a vertical diametrical section of the culvert with located it in the highest position regulating element with vodozapornyh valve and floating openings in the other pair of edges of pacotaco porous body.

Figure 4 - cross section b-b In figure 3, the horizontal cross section of the edges of the porous body with five output holes.

Figure 5 - cross section G-g of figure 3, the horizontal cross section of the edges of the porous body at the location of the three outputs.

Figure 6 - cross section d-D in figure 2, the horizontal cross section of the edges of the porous body with a hole in the ribs is of votacao porous body.

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

Injector for drip irrigation is connected to an irrigation pipe with flexible hose. To connect flexible hose injector has a nozzle 1 outlet 2.

In the outlet 2 is the float regulating element 3 vodozapornyh valve 4 in its upper part. In the upper part of the outlet 2 on the float regulating element 3 is made valves 5 to release the air from the cavity of the outlet 2.

Porous housing 6 of the injector has an inlet 7 and outlet openings 8, 9, 10, 11 and 12. In the porous body 6 parallel to the outlet 10 in the ribs 13, 14, 15 and 16 pacotaco made floating holes 8, 9, 11 and 12. Number of ribs 13-16 on the housing 6 more than two and have a sawtooth shape.

Device for drip irrigation works in the following way.

After Assembly of the device and attach it to the irrigation pipeline porous body 6 with pokozachene 13-16 injector immersed in the soil. When water begins working cycle of the device. Water from the irrigation pipe through the hose through the nozzle enters the expansion chamber of the outlet 2. Through the inlet holes 7 water from the body of the outlet 2 of the injector enters the outlet openings 8-12 in the arable horizon of the soil and the us is down by the water the root layer. If the flow of water from the irrigation pipeline exceeds the flow through the holes 8, the float regulating element 3 POPs up and reduces the cross section of the inlet in the nozzle 1, it decreases the access of water in the porous body 6. With decreasing water level in the expansion chamber of the outlet 2 of the float regulating element 3 is lowered and the flow of water from the irrigation pipeline increases. Thus automatically maintains a preset flow rate of water through the holes 8-12 injector for drip irrigation. The gap between the regulating element 3 and the bottom part of the outlet 2 by stops eliminates the deposition of silt particles and impurities in the outlet 2 of the injector and this ensures uninterrupted operation of the float regulating element 3. All of this increases the uniformity of the artificial precipitation height of the injector 7. Floating holes 8, 9, 11 and 12 in the ribs 13-16 deliver water in the soil horizons differentially reducing the lower moisture content in the soil and the subsurface horizon.

The injector will supply water to the roots of woody plants on the depth of their penetration.
