Abstract
The invention discloses a bubbler root irrigator comprising threaded labyrinth channels. The bubbler root irrigator comprises a circular tube, wherein threaded labyrinth channels are arranged on the tube wall of the circular tube; a water inlet, a sand sluicing hole and a ventilating and water-guiding hole are formed on the circular tube; a filter screen is arranged in the water inlet; the water inlet is communicated with the threaded labyrinth channels; and a water outlet is formed at the tail part of the threaded labyrinth channels. Compared with the conventional micro-irrigator, the bubbler root irrigator of the invention integrates the threaded labyrinth channels, the water inlet, the sand sluicing hole and the ventilating and water-guiding hole into a whole, so the bubbler root irrigator is applicable in the bubbler root irrigation of various soils; and compared with exposed tubes on the ground, the service life of the bubbler root irrigator is prolonged from 3 to 5 years to morethan 20 years, and the construction cost thereof is reduced by more than 20%.
Description
Technical field
The invention belongs to a kind of micro-irrigation emitter in agricultural economy woods irrigation technique field, drought-hit area, particularly a kind of bubbler root irrigator comprising threaded labyrinth channels is used to solve water-deficient area economic forest water-saving irrigation.
Background technology
Water-saving irrigation is the major measure that the countries in the world developing modern agriculture is adopted, and slight irrigation has been widely used in the crop of high added values such as economic fruit, vegetables, flowers, medicinal material as the irrigation technique of a kind of advanced person in the water-saving irrigation.Irrigator is one of the most key parts of irrigation system, and the structure of irrigator and the quality of hydraulic performance thereof are very big to uniformity, anti-blockage capability, the lifetime of system influence of irrigation system.China develops aspect modern water-saving technology comparatively fast over past ten years, in greatly developing the process of modern water-saving irrigation, it is widely acknowledged, drip irrigation is the technology of water-saving, but there is following problem in it: drip irrigation pipe all exposes on the ground on the ground, not only influence farming, cause artificial destruction, and aging easily, and only be 3-5 service life.If the employing underground drip irrigation causes the obstruction of irrigator easily, where when obstruction take place be difficult for being found by the people, maintenance difficulty is big, if large tracts of land is changed hollow billet once more, difficulty of construction is big, the drip irrigation cost is also bigger, has limited the large tracts of land development of ground drip irrigation and underground drip irrigation thus.
In order to overcome the deficiency of above-mentioned drip irrigation project, the applicant is in the long term studies process, name is called " a kind of root-irrigation method of underground artesian spring that is applicable to trees " in 2008, applied for Chinese patent (application number: 200810150395.8), this patent application has proposed the new ideas that the spring root is irritated, and made a kind of simple assistant's irrigator, to be that the water that the microtubule of 4mm flows out imports crop root via assistant's irrigator by diameter, this application has proposed the theory that the spring root is irritated, not only overcome the shortcoming of ground and underground drip irrigation mode, hollow billet is increased to 20 years by 5-8 service life, and moisture directly added to the crop root position, realization is changed to irrigated crop by irrigated soil, reduced the obstruction of evaporation from land surface and irrigator, improved the utilization ratio of pouring water, the assistant's irrigator that provides in its technical scheme also is a kind of easy blank, does not form a kind of spring root truly and irritates product.
Summary of the invention
The easily aging and ND shortcoming when influencing farming, underground drip irrigation and easily stopping up and stop up of the ground drip irrigation that exists at above-mentioned prior art, the objective of the invention is to, a kind of bubbler root irrigator comprising threaded labyrinth channels is provided, adopt this bubbler root irrigator comprising threaded labyrinth channels, not only pipe-line system all can be imbedded below ground, water-saving result with infiltrating irrigation, and be difficult for to produce stop up, hydraulic performance well, change easily and keep in repair.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of bubbler root irrigator comprising threaded labyrinth channels, it is characterized in that, this bubbler root irrigator comprising threaded labyrinth channels is integrated, comprise a pipe, the screw-type labyrinth flow-path is arranged on the tube wall of pipe, water inlet, flushing sluice and ventilation water guide mouth are arranged on the pipe, screen pack is arranged in the water inlet, water inlet and screw-type labyrinth flow-path are connected, and are provided with delivery port at the afterbody of screw-type labyrinth flow-path.
The runner center line length overall 1500mm of above-mentioned screw-type labyrinth flow-path, runner beam overall 3mm, degree of depth 2mm, tooth depth 1mm, space width 4mm, when water inlet pressure was 10m, the flow of delivery port was 71/h.
Bubbler root irrigator comprising threaded labyrinth channels of the present invention, micro-irrigation emitter different from the past, screw-type labyrinth flow-path, water inlet, flushing sluice and ventilation water guide mouth are integrated in one, the soil that is applicable to various different soil properties carries out the filling of spring root, when soil water permeability is strong, water by delivery port all infiltrates, when the soil water permeability difference, the water that has little time to infiltrate flows out to enter by the ventilation aqueduct and oozes the pond, reaching two kinds of irrigation methods thus combines, to guarantee that moisture all enters crop root, irrigation water utilization ratio height.The long discharge section area of inner irrigator runner is big, threaded labyrinth runner center line length overall 1500mm, minimum widith are 2mm, and in the past labyrinth flow-path water dropper minimum widith at 0.5-1.2mm, runner center line length overall is about 100mm, threaded labyrinth runner fluidised form index is less than 0.5, and energy dissipating and turbulent flow are effective.It is simple in structure, has the characteristics of root filling and spring; Adopt this bubbler root irrigator comprising threaded labyrinth channels, its pipe-line system can all be imbedded underground, has only an end of bubbler root irrigator comprising threaded labyrinth channels to flush with ground, is similar to buried sprinkling irrigation; The replacing of inner bubbler root irrigator comprising threaded labyrinth channels, easy to maintenance because inner bubbler root irrigator comprising threaded labyrinth channels and hollow billet are that the slight irrigation of 4mm is connected by diameter, can simply dismantle and change; Because this bubbler root irrigator comprising threaded labyrinth channels flow is bigger, every strain tree only is equipped with 1, and fixed investment is less; Long service life, cheap because all pipelines are all imbedded below ground, is compared with the pipeline that is exposed to ground, and brought up to 20 year or more by 3-5 service life, and cost reduces more than 20%.
