Low-pressure drip

 

The invention relates to agriculture and can be used for irrigation of perennial plants. Dropper consists of a body mounted on hanging on the conductor pipe. To the wire with adjustable suspensions with a mechanism for regulating suspended corrugated sliding cone with corrugations. Corrugated sliding cone is made of opaque polymeric film or foil. Inside the cone is installed movable ring retainer. The apex of the cone directed toward made in the lower part of the housing opening. Using ring-retainer, pushing the cone, provide regulation of the diameter of the irrigated area in accordance with the distribution of the roots of plants. 3 Il.

The invention relates to agriculture and can be used for irrigation of perennial plants.

A known design of irrigation network for irrigation slope of the land, provided with outlets, including the case with a calibrated orifice (ed. St. 1304785 MKI a 01 G 25/02, B 15, 1978).

The disadvantage of this design of the outlet is to supply water at one point. This limits the irrigation area. To hydrate zone distribution comporno dropper, includes case with a calibrated orifice and a group of water outlet nozzles. Design dropper allows the release of water at several points on the area distribution of the roots of the tree. The disadvantages of this dropper is a reduction in the reliability of its operation due to the use of culverts as pipes, because the danger of clogging of the nozzles is higher than the calibrated holes.

The closest the present invention is a discharge (ed. St. 1020015, MCI And 01 25 G/ 02, B 27, 1983), including the flow regulator in the form of cork crane with a stepped widening orifice, the flow distributor in the form of corrugated cone with alternating open and closed from the end of chute-corrugations, the last of which is perforated and provided with a mechanism for regulating the angle of the corrugation.

The disadvantage is the closest of the device is its complexity, the complexity in the repair and inefficiency in irrigation of perennial crops (orchards, vineyards). Tree watering Mature trees will lead to the formation of the root system, limited by space moistened spot, which reduces the wind resistance of trees.

To eliminate the mentioned disadvantages allows offers is in the form of corrugated cone, installed coaxially into the water hole and provided with a mechanism for regulating the angle of the corrugation, in which corrugated cone made sliding of the blade, for example, opaque material and has calibrated coaxial water outlet hole using the adjustable suspension, representing, together with ring-lock mechanism for regulating the angle of the corrugation.

The essence of the proposed technical solution is that the implementation of the water distribution element in the form of sliding corrugated cone allows you to increase the size of the calibrated water outlet hole, split water on the number of points corresponding to the number of bumps of the cone, and to apply irrigation water according to the crown of the tree, increasing the diameter of the circle as tree growth, which stimulates the roots to spread and increases wind resistance. Execution of corrugated cone of opaque material to protect tree trunks tree from weeds.

Using the adjustable suspension corrugated cone is attached to the trellis wire, and its top is oriented relative to the body dropper and set of soon is regulirovaniya angle of the corrugation of the cone.

The essence of the proposal is illustrated by drawings, where Fig. 1 gives a General view of the drip from the side, Fig. 2 - arrangement of drippers along the row of trees, in Fig. 3 is a diagram of the change of wetting zone at different positions of the cone.

The proposed low-pressure drip includes a housing 1 mounted on the pipe 2, is suspended from the trellis wire 3. To this wire using the adjustable suspension with 4 controllers 5 is attached corrugated sliding cone 6 with corrugations 7, made for example of opaque material. Inside the cone is installed movable ring-retainer 8, the top of the cone 6 is directed to a calibrated hole 9 made in the lower part of the housing 1, and are accurately aligned him with articulated suspensions 4.

The work is low-pressure drip in the following order.

Before the beginning of the irrigation season make adjustment dropper on the operating mode. Using a rolling ring-retainer 8 specify the size of the irrigated area, pushing corrugated cone 6. Then also using the adjustable suspension 4 adjust the position of the cone 6 relative to the housing 1 infusion and its top relative to the axis of the calibrated orifice 9. If kapelln the abuser to the diameter of the trunk (Fig. 2). The cone can be made of a polymeric film or foil.

When irrigation water is fed into the pipeline 2, it fills the body dropper 1 and flows through the opening 9 at the top of the cone 6. The alignment of the top of the hole 9 provides the separation of the stream into separate streams flowing over the bumps 7 to the lower edge of the cone, where as drops or small streams fed to the soil surface. Because the number of bumps can be 8-10 or more, the flow of water through a calibrated orifice 9 may be increased to 60 and 80 l/h, the Diameter of the holes 9, respectively, is increased to 5-8 mm. This dramatically increases the reliability of the dropper.

Before the next irrigation season can be made to increase the area of irrigation, accordingly, to increase the area of distribution of the root system of the tree. This increase is the opening of the cone 6 in width by moving the ring-retainer 8 up using the adjustable suspension.

Thus, the proposed low-pressure drip much easier constructively, which increases its reliability, maintainability and efficiency in the irrigation of perennial plants.
