Description
Technical field
The present invention relates to a kind of drip irrigation hose, relate in particular to and a kind ofly form the first-class waterpipe and second water pipe at drip irrigation hose, second water pipe is planned to a plurality of sections, make drip irrigation hose inside no matter produce how much hydraulic pressure and all can discharge the impartial water yield by the apopore of unit section formation separately, guiding helps the drip irrigation hose of the balanced growth of crops.
Background technology
Drip irrigation hose is installed on the ground near crop root in arviculture usually, makes the inner flowing water of flexible pipe be fed to ground by the peripheral limbers that forms of flexible pipe.Generally speaking drip irrigation hose is for continuous drop low amounts of water earthward, and the water flowing aperture is minimum, is convenient to flowing water and drop by drop evenly and lentamente drops near the crop root the soil by the limbers.
Conventional hoses because of high more near watering hydraulic pressure more, apart from watering more far water press lowly more, the phenomenon that hydraulic pressure eminence output is big, hydraulic pressure lower output is few usually can appear.And drip irrigation hose just for no matter the flexible pipe inside water pressure all can supply equal water gaging to crop by limbers separately.The high-quality drip irrigation hose should irrespectively can be supplied the water of equal equivalent by limbers separately with the inner hydraulic pressure that produces of flexible pipe.In other words, different its speeds of growth of crop output are also different, and therefore in order to reach balanced growth purpose, impartial water gaging need be supplied in a plurality of limbers that form in the drip irrigation hose.
Former proposition early much can be offset the inner various drip irrigation hoses that produce hydraulic pressure of drip irrigation hose, wherein or have a plurality of impedance bodies with impedance structure are installed on the limbers that drip irrigation hose supplies water earthward, or forms drip irrigation hose with dual pipe.The purpose of making drip irrigation hose with dual pipe is that film of synthetic resin is the bonding end in the stacked curling back of round shape part, forms outside water pipe so that form inboard water pipe and stacked place in the inboard.SEAL is vertically dropped in effluent waterpipe inboard outside, make inboard and outside water pipe form a plurality of inboard limbers of a determining deviation, the peripheral limbers, the outside that is communicated with that forms of outside water pipe and flexible pipe, the water of inboard water pipe supply flows into outside water pipe by inboard limbers, supplies water to the flexible pipe outside by limbers, the outside again.
Even if the water of the inboard water pipe supply of above-mentioned drip irrigation hose outside water pipe can arrive limbers, the outside, also difference appears in the water yield that can cause because of the pressure reduction that inboard water pipe produces supplying outside water pipe.And the past drip irrigation hose generally adopts the synthetic resin flexible pipe, do not have to be prone between delivery period the inboard drying of flexible pipe be close to the back flowing water that causes supplying water can not be by the problem of flexible pipe inboard.
In addition, once mentioned in " drip irrigation hose " of the prior art, shown in Fig. 1 a and Fig. 1 b, adopt prominent ring 105 to make it keep a determining deviation between drip irrigation hose internal perisporium 106 and the periphery wall 107, inboard water pipe 101 supplies water the back to internal perisporium 106 generation hydraulic pressure, make internal perisporium 106 diameters greater than periphery wall 107 or be equal to, the periphery wall 107 of being close to no hydraulic pressure forcefully, thereby keep spacing to diminish with outside water pipe 103 cross sections that prominent ring 105 forms, reduce the plus-pressure that puts on internal perisporium 106 at inboard water pipe 101 hydraulic pressure smaller parts, because of prominent ring 105 makes outside water pipe 103 more free from worry, thereby reach output equalization by limbers, the outside 104.But the above-mentioned utility model of registration earlier only depends on equally and keeps spacing can't ensure balanced hydraulic pressure in the drip irrigation hose with prominent ring 105, and is adjacent to phenomenon between the dry rear hose and is not resolved yet.
Also have, in the prior art " decompression liner and the drip irrigation hose that utilizes it ", it is higher to be used for reduce pressure the relatively outstanding position of impedance of section, the outstanding position of punching between the apopore of liner L machined surface moulding of drip irrigation hose H as shown in Figure 2, form corresponding outstanding position with flexible pipe periphery in the flexible pipe thermal bonding because of the outstanding position of above-mentioned punching, the drip irrigation hose H of the L shaped one-tenth of joint liner on flexible pipe is provided thus, this liner L optionally uses incision (incise) mode and rejecting (pick) mode, forms drainage arrangement T1 in the punching operation.But this class drip irrigation hose H needs joint liner L on flexible pipe T in addition, also needs punching drainage arrangement T1 on flexible pipe T, has caused the rise of manufacturing cost.And, only depend on liner to reach and regulate the hydraulic pressure purpose.

Tabular resin film two ends because of welding circuit 11 mutual thermal welding cyclic coils after, not only form first-class waterpipe 1 in that the tabular resin film is inner, same at tabular resin film joint because of 2 welding circuits, 11 formation, second water pipe 2.
Simultaneously stacked place additional lateral increase form one or more welding circuit 11 ', 2 welding circuits 11 that make vertical formation and horizontal welding circuit 11 ' link to each other, stacked place is planned as an above unit section.
The unit section forms a plurality of, horizontal welding circuit 11 ' formation more than two at drip irrigation hose A, adjacent welding circuit 11 ' have uniform distances a plurality of units section spacing is equated simultaneously, certain cultivation spacing that can corresponding crop.
The unit section is by two vertical welding circuits 11 and two horizontal welding circuits 11 ' form extra one or more the welding circuit 11 that vertically forms of section central authorities of unit ", the unit's of making section second water pipe 2 form two above unit water pipes 21,21 '.
This moment 11 ' terminal linking to each other with vertical two welding circuits 11 of horizontal welding circuit gets final product, and need not and vertically welding circuit 11 vertical formation.Be not that straight line forms as shown in Figures 3 and 4, vertically in the welding circuit 11 arbitrary and the extra welding circuit 11 that forms " link to each other, additionally the welding circuit 11 of formation " again with vertical welding circuit 11 in arbitrary the formation that links to each other, do not limit its form.
The water that first-class waterpipe 1, second water pipe 2 and each unit water pipe 21,21 of drip irrigation hose A ' answer UNICOM to make is fed to first-class waterpipe 1 is flowed, shown in Fig. 5 a, form in vertical welding circuit 11 of unit section arbitrary, be that tabular resin 10 ends are positioned at and form water supply hole 11a on the welding circuit 11 of drip irrigation hose A inboard, make in the first-class waterpipe 1 water to 2 supplies of second water pipe.
An other vertical welding circuit 11, promptly tabular resin 10 ends are positioned on the welding circuit 11 in the drip irrigation hose A outside and form and the identical shaped apopore 11b of water supply hole 11a, make the water row who is fed to second water pipe 2 to the external world.Shown in Fig. 5 c, the extra vertical welding circuit 11 that forms that increases " is gone up the same opening part 11c that forms, is made 2 itemize bit stream waterpipe 21,21 ' intercommunications.Simultaneously shown in Fig. 5 b, the part that does not form water supply hole 11a, apopore 11b and opening part 11c certainly will be planned as separately first-class waterpipe 1 and unit water pipe 21,21 '.
Owing to constitute this type of unit section, flowing water by each unit section second water pipe 2 unit water pipes 21 can irrespectively keep certain hydraulic pressure with the flowing water hydraulic pressure by first-class waterpipe 1, thereby the water yield that each apopore 11b that flows through is discharged reaches impartial.
In addition, the welding circuit 11,11 of present embodiment ', 11 " form by thermal welding or high frequency welding method, this type of thermal welding and high frequency welding technology belong to has announced technology, detailed here.
The tabular resin film 10 that present embodiment uses can adopt multiple synthetic resin materials such as polythene PE, polypropylene PP, do not limit the material kind, also can add other additive allotment and make, can adopt all kinds resin film of original production drip irrigation hose or conventional hoses at synthetic resin.
Present embodiment tabular resin film needs to form small male and fomale(M﹠F) 10a on tabular resin film 10 1 surfaces as shown in Figure 6, thereby makes first-class waterpipe 1 and second water pipe, the 2 inboard same small male and fomale(M﹠F) 10a of formation.Small male and fomale(M﹠F) 10a can prevent that also flexible pipe A is close to phenomenon mutually after not using the inner drying of drip irrigation hose A so that flexible pipe.
Flexible pipe inside does not originally have small male and fomale(M﹠F) 10a, is prone to flexible pipe inner peripheral place and is close to phenomenon mutually after drying, causes the water flexible pipe inside of can't flowing through even if be close to power because of it after supplying water yet.The present invention has solved this problem by this type of small male and fomale(M﹠F) 10a.
Small male and fomale(M﹠F) 10a can form in several ways, for example behind the film extruder heating extrusion resin raw material, still make immediately between its lower roll and the top roll that do not form projection by having minute grooves in that the condition of high temperature is following at the extrusion film surface temperature, thereby only form small male and fomale(M﹠F) 10a in a side.The concavo-convex quantity of small male and fomale(M﹠F) 10a, specification etc. are unrestricted at this moment.
The drip irrigation hose A of present embodiment is planned as a plurality of units section in addition, water by first-class waterpipe 1 supply is redistributed to each unit section draining, even if the inner foreign matter of sneaking into of drip irrigation hose A also only can influence the apopore 11b that forms in the unit section, reduced the drip irrigation hose clogging to greatest extent.
And each unit section has only a water supply hole 11a, apopore 11b and opening part 11c, and it forms the word shape that the position is, and promptly each unit section guarantees the water pipe that certain-length is above, to keep certain hydraulic pressure.
The first embodiment drip irrigation hose (A) can additionally not form vertical welding circuit in section central authorities of unit, thereby second water pipe 2 is not planned as two above unit water pipes as shown in Figure 7 yet.This moment, water supply hole 11a was arranged in a side of 11 arbitrary in vertical welding circuit of component unit section, apopore 11b is arranged in other one opposite side of vertical welding circuit 11, the water of the water supply hole 11a that prevents to flow through without second water pipe 2 and directly row to apopore 11b.
Present embodiment drip irrigation hose (A) after planting or before the sowing is installed in crop, can only in crop (sowing position) side drip irrigation hose (A) be installed as shown in Figure 8, also can install in both sides, does not limit it form or quantity are installed.
In sum, the present invention is illustrated with regard to above embodiment, but under the situation that does not surmount invention main idea and scope, the present invention can carry out various deformation and implement.
