Description
Technical field
The utility model relates to the instrument that topdresses in a kind of water-saving irrigation industry, particularly
oneplant the irrigate band with concentric screen pack.
Background technology
At present, fertilizer technology is to the future development of high concentration, Composite, fluidization, slow.Water soluble fertilizer is low owing to having producing cost, and nutrient content is high, be easy to compound, can directly be absorbed by crops, is convenient to the plurality of advantages such as rational application of fertilizers and mechanical chemical fertilizer, is more and more subject to the common concern of various countries.
More easily absorbed by crops than traditional fertilizer, water soluble fertilizer is a kind of polyelement composite fertilizer that completely can be water-soluble, it can promptly be dissolved in the water, and its absorption rate is relatively high, more crucially the application process of water soluble fertilizer is very easy, it can apply spray, drip, the industrialized agricultures such as filling comprise sprinkling irrigation along with irrigation system, apply fertilizer when the modes such as drip irrigation are irrigated, realize water-fertilizer integral, reach water-saving, economize fertile, the usefulness of less manpower, again save fertilizer, and saved labour, this today of growing to even greater heights in labor cost, the benefit of applications of water soluble fertilizers is apparent.Therefore, drip irrigation is the agricultural irrigation mode of a kind of advanced person, supplies feedwater by the irrigate band or drip irrigation pipe being placed on crop root, irrigate band has a lot of very little delivery port, from the water slowly wetting crop rhizosphere soils that delivery port overflows.Due to humidity temperature range-controllable, therefore, drip irrigation is the most effective current Water Saving Irrigation Mode, and except economizing on water, also section reduces fertilizer loss, promotes plant growth.At present, Water soluble fertilizer obtains large area extensive use in the northern area of China, achieves good effect.
Drip irrigation technique is by the water dropper on main, arm and hollow billet, under low pressure drips lentamente to soil, is a kind of irrigation system of moisture, fertilizer or other chemical agents etc. filtered directly to soil supply.It is not sprayed water or irrigation canals and ditches flowing water, only allows water slowly ooze, and enters soil under the effect of gravity and capillary.Water near instillation crop root, makes the soil in crop main root district often keep optimum water status.This is the irrigation method of a kind of advanced person.
But at present, water-soluble fertilizer does not have the fertilising facility of specification, and some facility floor spaces are excessive, it is not tolerant that some facilities cannot filter in Water soluble fertilizer, causes drip irrigation pipeline to block.Drip irrigation is with various structure, mainly be divided into labyrinth type drip irrigation tape and interior edge patch type drip irrigation tape, the maximum irrigate band of current usage amount is labyrinth type drip irrigation tape, the hydraulic pressure pressure reducer (decompression runner) be interlinked to the outside in one is set at a certain distance with wall, namely a water dropper is bonded at spacing intervals, pressure reducer is by the bending coiling of the capillary duct of certain diameter (such as 0.8mm) (in labyrinth type) form, irrigation water is through capillary channel repeatedly crooked pressure reduction, irrigation water is made to be drops instillation root soil, supply moisture.In addition, labyrinth type drip irrigation tape and interior edge patch type drip irrigation tape complex manufacturing, under hot melt state, labyrinth sheet water dropper and the continuous water dropper of joint strip are bonded in LDPE tube wall and obtain respectively, product quality cost is higher, and flank irrigate band technique is simple, be form by vacuumizing pressing after extruder extruding pipe material under hot melt state, but existence can not be durable in use, runner is easy to blocking, the shortcoming that anti-clogging is bad.
As can be seen here, because water must flow through the very little runner of diameter, for preventing blocking pipeline, very high to irrigation water quality requirement, before entering runner, need to filter irrigation water.Even if but irrigation water is through the centrifugal filtration of stem, still have the husky particle matter that waits of soil on a small quantity and be mixed into irrigation water, block capillary runner when flowing through the hole of water pressure-reducing valve, water outlet is had some setbacks or inequality, affect result of use and life-span, the penetration and promotion of serious restriction drip irrigation.Existing irrigate band, except high expensive, best problem can not effectively prevent from silt, root of the crop palpus etc. from entering in its runner to cause deposition blocking, and then affect the circle of drip irrigation system, causes maintenance cost to increase considerably.
Based on previous reasons, the utility model provides
oneplant the irrigate band with concentric screen pack, in the runner of irrigate band, current first flow into water dropper again after the filtration of screen pack, effectively prevent from the impurity such as silt, root of the crop palpus from entering water dropper to result in blockage, have a strong impact on the use of irrigate band, simultaneously, reduce the maintenance cost of labour intensity and irrigate band, there is higher practicality and economic benefit.
Summary of the invention
The purpose of this utility model is to provide
oneplant the irrigate band with concentric screen pack, in the runner of irrigate band, current first flow into water dropper again after the filtration of screen pack, effectively prevent the impurity such as silt, root of the crop palpus from entering water dropper and result in blockage.
To achieve these goals, the technical solution adopted in the utility model is: described a kind of irrigate band with concentric screen pack, comprise irrigate band, described irrigate band is the irrigate band of hollow cylindrical, it is characterized in that: be nested a cylindrical filtration in the cavity of the irrigate band of hollow cylindrical, and the cross section of the irrigate band of described cylindrical filtration and hollow cylindrical is concentric structure; The side of described cylindrical filtration is provided with the numerous mesh playing filtration, and the side of described cylindrical filtration is fixed on the cavity of the irrigate band of hollow cylindrical respective inner by bracing frame makes cylindrical filtration cover be embedded in the cavity of the irrigate band of hollow cylindrical; The side of described irrigate band is provided with the hole for connecting water dropper kept at a certain distance away; Be connected with the water inlet of water dropper by hole, crop root is inserted in the water side of water dropper.
The aperture of the mesh of described cylindrical filtration is 60-150 order.
The material of described cylindrical filtration adopts polyethylene or polypropylene or Kynoar or polytetrafluoroethylene (PTFE).
The water inlet of water dropper is directly inserted in hole, crop root is inserted in its water side simultaneously, thus realize the object of drip irrigation; Hole also can directly use as irrigating hole, and the liquid fertilizer in the runner of irrigate band flows through hole, infiltrates into crop root from upper soll layer.
The aperture of the mesh of described cylindrical filtration is 60-150 order, and mesh aperture is excessive, then do not produce the effect of filtering, and the impurity such as silt easily pass and then enter after in water dropper pipe and produce the problem blocked equally; Mesh aperture is too small, though be beneficial to the filtration of impurity, causes current osmotic pressure to increase.Therefore, the large I of mesh aperture is preferably 80-100 order.
The beneficial effects of the utility model: after concentric screen pack is set in the runner of irrigate band, current then in runner first must flow into water dropper again after the filtration of screen pack, thus realize filtering function, effectively prevent from the impurity such as silt, root of the crop palpus from entering water dropper to result in blockage, simultaneously, the maintenance cost of irrigate band, has higher practicality and economic benefit.
