Description
Technical field:
The utility model belongs to agricultural irrigation water delivery technical field, is specifically related to the embedded infiltrating irrigation pipe of a kind of outer edge.
Background technology:
According to statistics, China's agricultural water accounts for more than 80% of national total water consumption, using water wisely, reduces the loss of water, and development high-efficiency water-saving agricultural has become the fundamental state policy of China.The form of agricultural irrigation is a lot, and have furrow irrigation, sprinkling irrigation, drip irrigation and infiltrating irrigation etc., wherein with infiltrating irrigation science and advanced person the most, after pouring water, soil still keeps rarefaction, not spoiled soil structure, does not produce sealing of soil; Surface soil humidity is low, can reduce evaporation from land surface; Underground imbedded by pipeline, reduces floor space; Irrigation quantity is few, and efficiency of pouring water is high.Infiltration irrigation technology adopts the soakaway trench with some water seepage holes to be layed in farmland, forest land, nursery etc. on the ground, be connected water source again, water is oozed out through water seepage hole by the hydraulic pressure improved, with wetting soil, supply the moisture of planting in soil needed for plant, reduce through sunlight according to the evaporation discharge shining moisture, water-saving 80%, saving of labor 85%.Existing infiltrating irrigation pipe has the following disadvantages: 1, bury soil outward and suction function causes line clogging, is difficult to inspection and maintenance; 2, water dropping openings flow instability, is difficult to accurately control water percolating capacity; 3, infiltrating irrigation pipe mechanical strength is low, is difficult in the comparatively long distance laying of deep soil.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of background technology and provides a kind of antiseepage hole plug, accurately can control water yield and have the embedded infiltrating irrigation pipe of outer edge of good mechanical strength.
The embedded infiltrating irrigation pipe of a kind of outer edge, is characterized in that, comprises embedded water dropper and outer edge is short oozes pipe, and the water dropper be embedded in water-supply-pipe comprises the current stabilization road of band current stabilization effect, and the water delivery tube wall below current stabilization road current punches, and water oozes along pipe tap after current stabilization; Inlay one outside the position of corresponding described pipe tap edge is short outward and ooze pipe, the short inside pipe wall that oozes of described outer edge is provided with flow path groove, and the width of respective tube cinclides place flow path groove is at least 2 times of pipe tap diameter, and water oozes out along the short flow path groove water seepage hole oozing pipe of described outer edge.
Described outer edge is short oozes that pipe is outer to be set on the outer tube wall of described embedded water dropper, adopts the mode of two panels engaging to fix, and two panels is inlayed outward and shortly oozed the part that pipe is connected and be provided with in conjunction with wall, by conjunction with the engaging nail of the Φ 1.5mm of 4 on wall and connecting hole engaging.
Short the oozing on inside pipe wall of described outer edge is evenly distributed with 4 studs, and two panels is inlayed the short rear stud of pipe clamp conjunction that oozes outward and can be stuck on the outer tube wall of described embedded water dropper.
The outer tube wall at described embedded water dropper two ends is provided with the water stopping trough of annular protrusion, the short two ends of oozing pipe of described outer edge are provided with chuck, chuck is fixed on the outside of water stopping trough, can ooze out by anti-sealing, can play again the short effect of oozing pipe of fixing described outer edge at the short pipe two ends of oozing of described outer edge.
According to the described embedded dripper spacing of water consumption adjustment of irrigated crop, when the tube wall of described embedded water dropper punches, sychronisation is used to be fixed on the outer tube wall of corresponding embedded water dropper by short for the described outer edge pipe that oozes.
Short to ooze effective injection machine shaping for described embedded water dropper and outer edge, and described embedded water dropper and water-supply-pipe use LLDPE, LDPE or HDPE material, and the short pipe that oozes of described outer edge uses HDPE, PP or ABS material.
Preferred described outer edge is short oozes pipe range 37mm, the long 33mm of described embedded water dropper, and the short flow path groove oozing pipe of described outer edge is provided with 6 water seepage holes.
Preferred described water-supply-pipe external diameter Φ 16mm, described outer edge is short oozes pipe external diameter Φ 19.6mm, the long 1.5mm of stud, diameter 1.5mm.
External diameter specification commonly used by water-supply-pipe of the present utility model is Φ 12mm, Φ 16mm or Φ 20mm.For external diameter Φ 16mm, provided underground length can reach 80 meters, compensationly lays 200 meters.The pressure using infiltrating irrigation pipe is 0.05MPa-0.3MPa, and water yield flow per hour can be controlled in 2L-40L, and can realize accurate control.Outer edge of the present utility model embedded infiltrating irrigation pipe inside and outside wall is smooth, decreases the possibility that root system of plant is wound around pipeline.By increasing pipe thickness, can buried 0.1-0.5 rice, low temperature frozen pipe can be prevented by underground is buried.Bound moisture filtration treatment system and the measure such as precipitation return duct lower than infiltrating irrigation pipe height, can ensure that product uses more than 10 years.
The embedded infiltrating irrigation pipe of outer edge of the present utility model is mainly used in buried plant, trees are irrigated.Take full advantage of the stability that embedded water dropper drips, outer edge is short to be oozed pipe and plays the embedded water dropper apopore of protection and do not buried soil blocking outward and prevent negative pressure from sucking the effect of earth, and plays external compensation, make infiltration evenly.Thoroughly solve buried irrigation product blocking sex chromosome mosaicism.The embedded infiltrating irrigation pipe scope of application of outer edge of the present utility model is extensive, without geology soil and crop restriction.Can be buried, also can use on earth's surface.Different according to long-term cropping, imbed the suitable degree of depth, by ground mulching mulch film, heat transpiring moisture, the moisture under making crop make full use of mulch film.Cold district can reduce once a year by the way that irrigate band is irrigated, and greatly reduces the waste of recruitment and material.
The embedded infiltrating irrigation pipe of outer edge of the present utility model can realize full-automatic production and laying, and production efficiency is high, cheap, and have good market prospects, materials are nonpoisonous and tasteless, meets the idea of development of national low-carbon environment-friendly.
