Description

Anti-clogging is from overflow-type subsurface trickle irrigation device
Technical field
The utility model belongs to the anti-blocking equipment technical field of drip irrigation, is specifically related to anti-clogging from overflow-type subsurface trickle irrigation device.
Background technology
Underground drip irrigation (Subsurface Drip Irrigation, be called for short SDI technology) be one of typical apply form of micro irrigation technology, it refers to that water slowly goes out stream by the irrigator on buried hollow billet, soil near infiltrating, relends and helps capillarity or Action of Gravity Field moisture diffusion to be absorbed for crop to whole layer.Due to less to soil structure disturbance in water-pouring process, be conducive to keeping root of the crop layer to loosen penetrating environmental condition, and terramycin dregs loss can be reduced, therefore underground drip irrigation technique have obvious water-saving and yield-increasing benefit.In addition, after field water-carriage system is buried, be convenient to farming operation and Crop Planting Management Agriculture Expert, and buried rear tubing ageing resistace strengthens, not easily lose or artificial damage.
Underground drip irrigation is a kind of by buried for the drip irrigation pipe a kind of drip irrigation method in soil under earth's surface, be transported to buried in the hollow billet of underground with pump handle water, from the moistening underground of delivery port drip irrigation hollow billet, current underground drip irrigation as one economize on water most in drip irrigation, technology that energy-conservation, efficient irrigation method has broad based growth prospect and using value, become the primary study direction of many agricultural science and technology mechanisms at home and abroad.The major advantage of underground drip irrigation is: 1, water-saving ability is remarkable, the plant nutrition needed for plant and moisture directly can be sent to root system, avoids the moisture evaporation problems that drip irrigation is on the ground brought.2, the service life of drip irrigation equipment especially irrigate band is extended, because irrigate band is embedded in underground, avoid farming operation or animal to the destruction of irrigate band, and the problem of aging of the irrigate band preventing ultraviolet and day and night temperature change etc. to cause, increases the service life.3, moisture directly enters root system soil layer, is conducive to root system and grows downwards, and earth's surface is dry, good permeability, is conducive to the breathing of root system of plant and suppresses the growth of weeds.4, avoid because surface irrigation brings the various diseases that there was dampness in the air and cause.5, reduce field management labour intensity, save administrative expenses, be convenient to again the operation of machinery in field.6, impel root system deeply to prick, avoid frostbite root system etc. of freezing to death winter.
At present, the underground drip irrigation equipment used both at home and abroad all from ground drip irrigation system, water dropper often adopt internally-inlaid or directly buried with the water dropper of compensation performance after for irrigating.But find that underground drip irrigation exists problems by large-scale field trial all over the world, as lack of homogeneity of pouring water, water dropper easily blocks, crop root likely wears out hollow billet, the problems such as system maintenance difficulty still exist, and the development speed that also therefore result in underground drip irrigation technique lags far behind surface irrigation.Produce negative pressure in pipe network due to underground drip irrigation system of being everlasting when stopping is supplied water, cause the Soil fine particles around hollow billet apopore to be inhaled into water dropper, cause emitter clogging.This has become underground drip irrigation system development and a bottleneck problem in applying.For solving water dropper negative pressure blockage problem, the method abroad adopted at first installs vacuum breakdown device of vacuum at the peak place of system main pipe, eliminates the adverse effect that in pipe network, negative pressure is brought whereby.This technology can eliminate the negative pressure in pipe network, reduces the blocking of negative pressure appearance, but can not prevent entering of solid tiny particle and entering of plant root, and water dropper still can blockage phenomenon, and the performance of anti-blockage of this technology in applying is not too obvious.After this, human hair is had again to understand by adopting the process of outsourcing non-woven fabrics buried to insert emitter China is domestic, after water supply stops, micropore due to non-woven fabrics has good air-and water-permeable function and filtering function, solid tiny particle is prevented to enter water dropper, can prevent again the hydrotropism's blocking dropping head due to root system of plant simultaneously, thus have good anti-negative pressure anti-clogging function, anti-negative pressure blocking and raising uniformity aspect all obtain certain effect.But the problems such as the forming technology of outsourcing filtrate is complicated and cost is higher, increase system investments cost.This project organization not can solve again the deposition blocking of pipeline water adding system solid particles inside thing, and therefore the design of this structure is subject to certain limitation in applying.
Summary of the invention
The purpose of this utility model will provide one can stop root system and soil particle clogging drip irrigation pipeline exactly, extends the anti-clogging in droping irrigating pipe service life from overflow-type subsurface trickle irrigation device.
The utility model is achieved through the following technical solutions:
Anti-clogging is from overflow-type subsurface trickle irrigation device, primarily of drip irrigation pipe joint 1, be connected on drip irrigation pipe joint 1 drip irrigation in pipe 2 and the protecting tube 3 be located in drip irrigation outside pipe 2 form, it is characterized in that: in described drip irrigation, between pipe 2 and protecting tube 3, be provided with collect cavity 4; By the lattice catch 5 in described drip irrigation between pipe 2 and protecting tube 3, collect cavity 4 is divided into some chambers in described collect cavity 4; In described drip irrigation, pipe 2 is provided with apopore 6.
In described drip irrigation, pipe 2 is made up of elastomeric material.
Protecting tube 3 upper end of described side, close earth's surface is connected with discharging device 7; Described discharging device 7 is connected with chamber.
Described discharging device 7 is water dropper, shower nozzle or water outlet bolt.
Reverse flow check valve 8 is provided with between described discharging device 7 and chamber.
Compared with prior art, the beneficial effects of the utility model are:
1) in drip irrigation, pipe 2 and the protecting tube 3 be located in drip irrigation outside pipe 2 adopt, and make pipe in drip irrigation 2 be socketed in protecting tube 3, solve the problem that in drip irrigation, pipe 2 is easily corroded.
2) employing of collect cavity 4, drip-irrigation water is made first to enter in collect cavity 4 by apopore 6, overflowed when water in collect cavity 4 enters reverse flow check valve 8 automatically after being full of, eliminate the negative pressure in pipe network, reduce the blocking of negative pressure appearance, but entering of solid tiny particle and entering of plant root can not be prevented.
3) in drip irrigation, pipe 2 adopts elastomeric material to make, and the apopore 6 be located under water pressure in drip irrigation on pipe 2 is expanded, and apopore 6 restores after water pressure disappears, and in the process expanded and restore, apopore 6 not easily blocks.
