The invention relates to agricultural irrigation, in particular to soil irrigation.

Known injector for drip irrigation, including outlet and a porous casing, which regulated the water supply and equipped with a pressure regulator, made in the form of a replaceable porous element. (SU, copyright certificate №812237.(51), MCL3A 01 G 25/02. Injector for drip irrigation / VK Gubin, GO sheikin and N.P. Mityanin (USSR). - Application No. 2773423/30-15. Declared 31.05.79; published 15.03.81, bull. No. 10.)

The disadvantage of this injector is the uneven distribution of precipitation in the zone of moisture both in terms of depth and area. In addition, the injector has a low reliability and low service life.

Known dropper, including collapsible chamber with the nozzle and the injector in the form of a pin with ribs converging to the tip of the pin, and the camera is positioned in the upper part of the injector and is equipped with a dispenser water supply and permeable hollow core placed in the cavity of the pin, while the lower part of the rod is made with a pointed end, and the pin between the ribs made water conveyance channels communicated with the cavity of the pin, the rod is made of a porous material in the form of a hollow body of circular cross section, and the dispenser water is made in the form of a hollow popla the ka with Subarus posted by needles. (RU, patent No. 2202879, IPC7A 01 G 25/02. 2003)

The disadvantages of the known drip is the design complexity, low reliability because of the possibility of overgrowth of porous material by phytoplankton, the lack of regulation of soil moisture at a depth of wetting.

The closest technical solution to the stated object is the drip, including mounted in the hole of the humidifier housing and mounted therein regulatory element made in the form of a float valve with one upper locking needle in the form of a pyramid on the top surface of the valve and oriented opposite to him a shut-off needle at the bottom part thereof, mating in the initial position of the float valve with outlet openings in the housing of the humidifier and the humidifier has the form of a U-shaped knees, the inner surface each provided with a labyrinth of channels in the form of alternating non-intersecting ridges and troughs, with U-shaped knee is formed by combining parts of the core of permeable material placed in the cavity of the injector. (RU, patent No. 2214087, IPC7A 01 G 25/02. 2003)

The drawback dropper is the low reliability due to overgrowth of holes permeable material phytoplankton, as well as the complexity of the design the products.

The essence of the claimed invention is as follows.

Task to be solved by the claimed invention is directed, enhanced operational reliability, ensuring uniform moisture root zone soil layer to both the area and depth of wetting.

Technical result - increase of operational reliability. This technical result is achieved by the fact that in the known injector for soil moisture, comprising a split housing made by helix groove on the peripheral part provided with a tapered hole, directed to the outside of the injector, and the diameter of the holes increases from the spiral grooves to the outer end of the injector, and a detachable housing parts are connected by a yoke, which serves as a stop for the bottom of the injector into the soil and tip.

The unit injector is illustrated by drawings.

1 schematically shows a diametrical section of the housing of the injector.

Figure 2 - the same kind in the plan.

Figure 3 is a view of the injector side.

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

The injector consists of a detachable fitting 1 and parts 2 and 3 of the casing. Inside parts 2 and 3 of the casing is provided a spiral groove 4. The internal cavity of the groove is connected with the outside the second surface of the conical injector holes 5, moreover, the diameter of the holes 5 in the inner cavity of the groove is smaller than that of the outer surface of the injector. Parts 2 and 3 of the casing are connected by a yoke 6, which has openings 7 bolt and the lug 8.

Preparation of the injector to work is to connect the halves of the enclosure through the yoke 6 and the tip 8 and the connection to the irrigation pipe fitting 1 with a hose.

The injector operates as follows.

The operator drip irrigation system plunges by clicking on the clamp injector into the soil. The length of the injector must be equal to the depth of wetting the entire root zone soil layer. Water from the irrigation pipe through the nozzle 1 flows into the groove 4. The water pressure in the irrigation pipe and gravity forces the water moves along the spiral groove. This causes centrifugal forces that push through the tapered bore 5 of irrigation water. The taper of the holes reduces the flow of water into the soil, its erosion and uniform wetting of the root zone soil layer. In addition, the expanding cone holes 5 prevents clogging of the discharge on phytoplankton. The injector will provide a uniform distribution of precipitation in the root zone soil layer the entire irrigation season.

1. Injector for soil moisture, comprising a split housing with depravadas channel, characterized in that the internal cavity of the housing is fitted with a spiral groove with a tapered holes on its surface, connecting the screw groove with the outer surface of the housing.

2. The injector according to claim 1, characterized in that the diameter of the conical hole, conjugated with groove, is smaller than the outer surface of the shell.
