The invention relates to techniques for irrigation of agricultural crops and is intended for use with drip irrigation.

Known dropper, comprising a housing with inlet and the membrane, in which, to improve reliability when the pressure in the network and the availability of irrigation water, mechanical impurities, input and output are namebrands cavity, and the entrance dropper made in the form of krivokolenny pipe, the inner end of which is installed perpendicular to the membrane and concentric with it and provided associated with the membrane cap having a lateral slot (SU inventor's certificate No. 1109091. A. MCL3A 01 G 25/02. Dropper / Aravantinou, Masakali, Mboyo (USSR). - Application No. 3589798/30-15; Claimed 06.05. 1983; publ. 23.08.1984, bull. No. 31).

The disadvantages described droppers include low operational reliability due to clogging debris outlet and a high degree of irregularity in the issuance of irrigation norms.

The closest analogue to the stated object is dropper comprising a housing and a flexible membrane, in which, to improve the reliability, efficiency and functionality, on the inner surface of each part of the body is tapered regulatory and spherical protective camera located appropriate estwenno coaxially with the housing bore and the hole in the membrane, when this chamber is communicated between a cavity, which can travel posted membrane and channels made in the form of a cut along the axis of the nozzle of Laval, tapering part of which is converted to a spherical protective camera, in addition, the membrane made additional aperture located coaxially with the conical regulatory cells (SU inventor's certificate No. 1586615. A2. M CL5. A 01 G 25/02. Dropper / Nasrudin, PTP, Assault (USSR).- Application No. 4600656/30-18; Claimed 03.11.1988; Publ. 23.08.1990, Bul).

The disadvantages described dropper adopted us as naiblizhajshee analogue, include low operational reliability due to clogging of the holes of the membrane plant and mineral litter and their agglomerates of large size and high degree of non-uniformity of issuance irrigation rates per unit time.

The essence of the claimed inventions

Task to be solved by the claimed invention is directed operational reliability technology of drip irrigation.

The technical result is an increase in uniformity of issuance of irrigation norms.

This technical result is achieved by the fact that known dropper containing the entrance and exit of the housing, on the inner surface of the logged spherical protective camera, located coaxially her outlet and Kahn the crystals in the form of a cut along the axis of the Laval nozzles, extending part, which is converted to a spherical protective chamber, and placed over it to move the membrane with holes according to the invention provided with the inlet opening threaded lid, float in the form of a hollow sphere, freely placed over the membrane, the annular chamber in the casing provided with a spherical protective camera tapering parts of the channels made in the form of a cut along the axis of the Laval nozzles, additional membrane having a drain hole bottom screw cap with mounted in the drain hole removable diffuser facing the additional membrane extended part, with the annular flange of the diffuser, interrupted radially oriented slots, paired with additional membrane at the outlet of the housing for movement.

The invention is illustrated in the drawing, which presents a dropper, diametrical section.

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

The dropper contains input 1 and output 2 of the housing 3. On the inner surface of the log 1 is made of a spherical protective chamber 4 located coaxially her outlet channels 5 and 6. The channels 6 are views cut along the axis of the Laval nozzles, extending part, which is converted to a spherical protective the chamber 4. Over a spherical protective chamber 4, the outlet 5 and channels 6 posted equipped with the ability to move with holes 7 and the diaphragm 8. The dropper provided with the upper threaded cap 9, the float 10, the annular chamber 11, an additional membrane 12, the lower threaded cap 13. The upper threaded cap 9 has an outlet 14. The inner cavity of the upper threaded cap 9 is made conical. The float 10 in the form of a hollow sphere freely placed over the membrane 8. The annular chamber 11 is made concentric with the outlet 5 and the spherical protective chamber 4 on the bottom part of the input 1 of the housing 2. The annular chamber 11 is communicated with a spherical protective camera 4 tapering parts of the channels 6, made in the form of a cut along the axis of the nozzle of Laval. The main membrane 8 and the additional membrane 12 is made equal and have the identical design. The holes in each membrane 8 (12) completed with a shift to the annular peripheral edge 15. Bottom screw cap 13 has a drain hole 16. The inlet opening 14 of the upper threaded cap 9, the discharge opening 5 of the housing 3 and the drain hole 16 in the lower threaded cap 13 is coaxially. From the drain 16 of the lower threaded cap 13 is mounted a removable diffuser 17. The extended part of the diffuser 17 is turned in the direction of additional membrane 12. The extension of the military part of the cone 17 has an annular flange 18, channeled radially oriented slits 19. The depth of the slots 19 and the height of the cone 17 are in the ratio 1:(3-8). The bottom cover 13 is provided with serological 20 extra membrane 12. It is posted on the output 2 of the case 3 can move. The annular flange 18 of the diffuser 17 is associated with the back side additional membrane 12.

The float 10 and the main membrane 8 into the conical cavity of the upper threaded cap 9 form a chamber 21 high pressure. Placed over the annular chamber 11, a spherical protective chamber 4 and 6 cameras main diaphragm 8 forms a cavity 22 medium pressure. Located above the annular chamber 18 of the diffuser 17 additional membrane 12 forms a cavity 23 of the low pressure. The flow of water dropper is determined by the number and depth of the slits 19 a removable diffuser 17 and the diameter of the drain hole 16.

The dropper works as follows.

The inlet opening 14 at the top of the threaded cap 9 connect the flexible hose to the nipple of the water distribution system piping drip irrigation. When water under pressure due to the momentum of the float 10 and the membrane 8 are pressed against the bottom part of the input 1 of the housing 2. The membrane 8 is pushed to the edges of the annular chamber 11, channels 6 and protective spherical chamber 4. When filling the cavity of the camera 1 of the housing 2 and to the practical cavity upper threaded cap 9 float 12 POPs up and closes off the inlet opening 14. In the chamber 21 is supported by the water pressure is equal at the entrance to the inlet. Simultaneously, through the opening 7 in the membrane 8, the water from the chamber 21 high pressure flows into the annular chamber 11 at the bottom part of the input 1. Vegetable and mineral Sora passed through the opening 7, are trapped in the annular chamber 11, as a narrowing of the camera 6 is made in the form of a cut along the axis of the Laval nozzles are located above the bottom of the camera 11. Due to the expanding shapes 6 channels water from the annular chamber 11 with a minimum of pressure and speed is reset in a protective spherical chamber 4. The jet streams of water radially oriented channels 6 are mutually inhibit each other, and the water under the action of gravitational forces from the cavity 22 medium pressure at the outlet 5 is supplied to the output 2 of the housing 3. The flow of water with suspended solids, microorganisms, tiny vegetable and mineral debris falls from the outlet 5 to the surface of the additional membrane 12. The peripheral edge 15 additional membrane 12 is attached on the bottom part of the sludge trap 20. SOR smoothly with the surface of the membrane 12 enters the perforated bottom 20 threaded cap 13. Water from output 2 on holes 7 in additional membrane 12 is fed into the cavity 23 of the low pressure. From the cavity 23 of the low pressure irrigation water through radial is oriented slits 17 enters the cavity of the cone 17, and then through its drain opening 16 is fed to irrigated land. Since the slits 19 are placed on the diffuser 17 above the level of the sludge trap 20, the weed part is not supplied to him. This contributes to the fact that irrigation water to the slots 19 is supplied only under the influence of gravitational forces. The presence of the annular chamber 11 and sludge trap 20 ensures high process reliability dropper. Removable diffuser 17 on the lower threaded cap 13 provides a wide range of irrigation rates.
