The invention relates to agriculture, namely, to drip irrigation.

Known irrigation device, comprising a pipeline with a dropper in the form of microporous tubes mounted transversely of the pipeline with the possibility of axial movement, one end of microporous tubes plugged and fitted each adjusting rod rigidly connected is and is low maintenance reliability due to possible clogging and compressed air for cleaning, result in unproductive labor, and loss of this environment, and the process takes a long time. In addition, the drip cause significant energy losses of water in the pipe, and the diameter must be increased, which leads to higher drip irrigation systems.

Known dropper installed across the drip line and containing a movable nozzle and coaxially associated tubular soft porous element, the second end of which is reinforced inside the drip line. The movable nozzle provided with a coaxially installed therein a perforated tube, one end of which is fixed in the hole of the pipe, while the porous elastic element is mounted on a perforated tube with the possibility of changing its cross section by rolling pipe, and the tube is provided with a lock position of the moving pipe.

The disadvantage of this dropper is the complexity of the design, as it is necessary to perform numerous holes across the axis of the pipe on both sides, as well as the reduction of operational reliability, if heavily contaminated irrigation water and within the pores of the elastic element accumulate small particles, o, dropper reduce the throughput of the feeder line so as to cause large resistance to flow, thus increasing its diameter. All this increases the cost of drip irrigation system. Thus the range of regulatory costs reduced.

The purpose of the invention improving the reliability by ensuring compromise, providing a controlled supply of water and simplify the design.

This objective is achieved in that the dropper consists of a flexible discharge tube with a porous member, and a regulating element, configured to change the cross-section of the tube by means of a rolling element. The regulatory element is designed in the form of a squeezing sleeve with an internal tapered bore, provided with a movable conical sleeve with a longitudinal slit and with a support washer at the base, with taper bushing is located between the jaws of the sleeve and the water outlet tube, squeezing the sleeve is provided with a coupling nut contact with the puck with the possibility of axial movement of the conical tube relative to the outer surface of the water outlet tube. While the water outlet tube is made of an elastic materiae is attached to the hole of the pipe.

This embodiment of the device and the combination of all characteristics is of small diameter irrigation pipe (humidifier) and does not create resistance within its cavity. In this case also is not only the best rinse the dropper, but also adjust the flow of water through the movable conical sleeve, movable locking nut in the inner conical hole squeezing sleeve and slotted grooves on the movable conical sleeve allow you to change the shape of the elastic water outlet tube in the cavity which contains an inert fibrous along the length of the material (for example, glass fiber, basalt fiber, etc.,), which is laid along in an elastic tube.

A positive effect is to improve the operational reliability of the droppers and unifying their details for prefabrication, when this happens the recovery process forms a drip when adjusting the water outlet channel in it. Tube of flexible resilient material has a resistance to corrosion in aggressive water irrigation to biological and mineral impurities of irrigation water that does not require expensive filters of thin clearing. In which enables you to dramatically reduce the requirement for water treatment, which is at least half of the cost of drip irrigation.

In Fig.1 shows the proposed dropper, longitudinal section; Fig. 2 section a-a in Fig.1.

Dropper consists of regulatory and porous element regulating element contains the squeezing sleeve 1 with an internal tapered bore 2, in which missing plastic, elastic, elastic culvert pipe 3, channel 4 which is placed a porous element made of an inert water wavy fiber 5 (for example, glass fiber, basalt fiber, etc ). Coaxially with the tube 3 is mounted movable conical sleeve 6 into the conical hole of the jaws 2 of the sleeve 1, and the movable conical sleeve 6 is slotted slot 7 (Fig.2) from the smaller base of more and more its base set thrust washer 8. On squeezing the sleeve 1 screw thread cap nut 9, the contacting its base with a support washer 8, so that together with the movable conical sleeve 6 to control fluid tightly compresses the plastic elastic, elastic culvert pipe. Slotted longitudinal slits allow the tapered bushing to reduce the inner diameter, thereby taper bushing to the other wavy fibers. This will reduce the screening area between the fibers. On the nut 9 from outer side of the scale is applied 10 on the jaws of the sleeve 1 label zero, which are designed for calibrating the required flow rate expires on droppers.

The dropper works as follows.

The drip is attached to the drip line fittings on the pipeline, to which is attached culvert pipe 3. Water under pressure enters the channel 4 of the tube 3 and through the fibrous capillary element seeps across the length and flows down in the form of drops into the soil.

Regulation of water consumption is due to a change in the working of the cross-section area of the channel 4 of the tube 3 at the location of the capillary element using the Union nut 9, a screw on squeezing the sleeve 1, and the nut 9 end presses on the washer 8 and moves the tapered sleeve in the form of a wedge in the cavity of the tapered bore 2 of the sleeve 1 on the surface of the pipe 3. The sleeve 6 with a longitudinal slit incisions begins to shrink, and consequently compressing an elastic tube 3, which, in turn, deforms (bends) and the effect on the fibrous element, pressing the individual fibers to each other, straightening vitsy.

When unscrewing the nuts 9 on the sleeve 1, respectively, the tapered end of the movable sleeve 6 is returned to its original position, the longitudinal slits increases, there is a bending elastic tube 3 and the flow through fibrous capillary element increases. Using the plotted scale 10 on the nut 9 and the mark of zero on the sleeve 1 is the scaling flow dropper in function of the degree of compression of the fibrous element 5. Scaling is performed using a beaker and a stopwatch. Getting the necessary flow expiration, dropper set up for irrigation. Thus, it is uniformly stable distribution of water along the length of the pipeline.

The positive effect from the use of the invention in comparison with the prototype is to improve the reliability of the droppers, since the automatic flushing of intravenous and restoration of patency culvert channel with capillary element is adjustable nut, while continuing watering, with increasing distance between the fibers, made of an inert material having a wavy shape that creates a change in velocity of the expiry of the channel length and constant vibration. This oznacza the project for a costly fine filter.

We offer the drip is simple in construction, can be easily replaced, if necessary, its removal to improve operation due to the possibility of self-purification, and at the same time, no increase of the cross section of irrigation pipe, i.e., can the pipeline to do small diameter, and this leads to a decrease in the cost of drip irrigation system, not less than 70% Implementation details dropper folding allows to simplify the manufacturing technology for mass production.

DROPPER containing mounted in the hole of the pipe body with the water outlet pipe, made of an elastic material, which regulates mobile and porous elements, characterized in that, to improve operational reliability by ensuring compromise, providing a controlled supply of water and simplify the design, the regulatory element is designed in the form of a squeezing sleeve with an internal tapered bore, a movable sleeve with a longitudinal slit from smaller to larger base and a support washer on a larger base, thus the mobile taper bushing is located between the jaws of the sleeve and the water outlet tube and squeezing the sleeve has nacido is it the surface of the water outlet tube, in the output channel which is porous element of typed inert wavy fibers.
