Description
Technical field
The utility model relates to the anti-blocking drip irrigation pipe in a kind of micropore labyrinth, particularly relates to the drip irrigation pipe of the buried application of a kind of applicable field crop, belongs to water-saving irrigation agricultural equipment technology field.
Background technology
The various embedded drip irrigation pipe of irrigation being applied in agriculture micro irrigation technology field is at present all on each water dropper, arrange one group of labyrinth, being used for damping and pin subtracts drip irrigation overpressure, the discharge pressure of balanced each drip-watering outlet and water yield, thus ensure that the water yield of drip irrigation pipe each drip-watering outlet in certain laying length is basically identical.Production method is generally on water dropper external cylindrical surface, be carved with various labyrinths groove or inlay labyrinth paster, and then water dropper is extruded in drawing and forming process in drip irrigation pipe and is embedded in drip irrigation pipe.
Due to drip irrigation pipe lay on the ground time, irrigation water evaporation loss is large, affect farming, need every year to reclaim, drip irrigation pipe is subject to the Exposure to Sunlight easily problem such as aging.So modern agriculture widelys popularize buried drip irrigation technique, exactly drip irrigation pipe is embedded in underground and uses.But when existing drip irrigation pipe, irrigate band are embedded in underground, the hydrotaxis of crop root can make fibrous root letter enter the drip-watering outlet of drip irrigation pipe; In addition, in interval of pouring water, the muddy water outside drip irrigation pipe, under suction function, can be recharged by drip-watering outlet, blocks by delivery port or near the labyrinth of exit portion.Because labyrinth length is generally 80 ~ 400 millimeters, labyrinth pin diminishing pressure effect has made end hydraulic pressure go to zero, and when again pouring water, labyrinth end hydraulic pressure cannot be washed open blocking part, causes drip irrigation system to scrap because of blocking.The defect that existing drip irrigation pipe/belt exists, becomes the bottleneck hindering the development of buried drip irrigation technique.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the anti-blocking drip irrigation pipe in micropore labyrinth cheap for manufacturing cost, to solve the problem that buried drip irrigation pipe blocks delivery port.
The technical solution of the utility model is achieved in that the anti-blocking drip irrigation pipe in this micropore labyrinth, be made up of drip irrigation pipe and embedded water dropper, water dropper is cylindrical, cylinder both sides or middle part arrange water outlet slit, the anti-blocking permeable layer in micropore labyrinth that cylinder jacket dress fibrous material or opening foaming poromerics make, water dropper arranges interval and is greater than 30cm in drip irrigation pipe, and drip irrigation tube wall corresponding water dropper water outlet slit location is staggered is uniformly distributed with apopore along the circumference.
The described anti-blocking drip irrigation pipe in micropore labyrinth, described water dropper two ends arrange seam with fixing anti-blocking permeable layer material.
The described anti-blocking drip irrigation pipe in micropore labyrinth, described water dropper two ends arrange annular groove and snap ring with fixing anti-blocking permeable layer material.
The described anti-blocking drip irrigation pipe in micropore labyrinth, described water dropper one end arranges seam, and the other end arranges annular groove and snap ring with fixing anti-blocking permeable layer material.
The described anti-blocking drip irrigation pipe in micropore labyrinth, described anti-blocking permeable layer material is acrylic, polyethylene, the braided sleeving of polypropylene fiber or opening braided sleeving.
The described anti-blocking drip irrigation pipe in micropore labyrinth, described anti-blocking permeable layer material is polyurethane opening expanded material.
The described anti-blocking drip irrigation pipe in micropore labyrinth, the water outlet crack of described water dropper be arranged in parallel along center line on the water dropper face of cylinder.
The technological progress effect of the anti-blocking drip irrigation pipe in the utility model micropore labyrinth is:
1, significantly improve anti-blocking performance, the infiltration space, micropore labyrinth formed due to fibrous material is minimum, and can reach micron order, crop fibrous root cannot be pricked and result in blockage into micropore labyrinth.Drip irrigation system filter plant can be simplified, reduce drip irrigation system operation energy consumption.
2, water dropper labyrinth shape is cartridge type, is directly sleeved on water dropper during production, and significantly reduce water dropper production technology cost, drip irrigation pipe production line hardware does not need to make any change.
3, pour water intermittently, when muddy water recharges and blocked out outlet under suction function, the micropore labyrinth flow process formed because of fiber gap only has several millimeters, when again pouring water, the capillary infiltration double action that the inside and outside differential pressure of irrigation water pressure initiation and water surface tension are formed, also can wash open blocking part.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The key problem in technology of the anti-blocking drip irrigation pipe in the utility model micropore labyrinth has created to be sleeved on packing material as micropore labyrinth flow-path on water dropper with microporous fibre or expanded material, the apopore of water dropper water outlet slit and drip irrigation pipe is crisscross arranged, by means of the capillarity of fibrous material, irrigation water is outwards oozed out again through drip irrigation pipe fibrous material from water dropper slit.
As shown in Figure 1: the anti-blocking drip irrigation pipe in micropore labyrinth of the present utility model, be made up of drip irrigation pipe 5 and embedded water dropper 4, water dropper is cylindrical, hollow space was water flow passage 6, in water dropper cylinder both sides, circumference arranges water outlet slit 3, the anti-blocking permeable layer 2 in micropore labyrinth that cylinder jacket dress fibrous material or opening foaming poromerics make, and water dropper arranges interval and determines by the amount of dripping in drip irrigation pipe, generally be more than or equal to 30cm, in the middle of drip irrigation tube wall corresponding water dropper water outlet slit location, be provided with apopore 1.
Fig. 2 provides another technical scheme of the present utility model, arranges water outlet slit 3 in water dropper cylinder intermediate circumference, and the corresponding water dropper water outlet slit location both sides of drip irrigation tube wall are provided with apopore 1.
