Description
Technical field
The present invention relates to manufacture method, watering pipeline, the manufacture method and the mist cooling means of watering pipeline of sprinkler, sprinkler of water operation and mist cooling etc. that nozzle as watering usefulness used or be used for the growing nursery and culture of the cultivations of weak vegetables etc. and paddy rice etc.
Background technology
In the facilities horticulture field of agricultural, carry out the growing nursery and culture of the cultivation, paddy rice etc. of weak vegetables etc. in the so-called vinyl plastics film greenhouse of being everlasting.During above-mentioned vegetable growing and seedling cultivation of rice, the operation of watering of every day is indispensable.
Here, the general method that adopts is in the operation of watering, and in the end of flexible pipe the watering utensil that can obtain spraying the shape watering is installed, and moves the limit at the greenhouse inner edge and waters.The operation of watering is so usually changeed warm March from temperature, and is the most necessary between the megathermal period when July in summer～by the end of September especially.In summer, the temperature in the greenhouse surpasses 40 degree, and this is one of operation the heaviest in the farm work.
In recent years, constantly carry out to alleviate the exploitation of the watering pipeline that such operation intensity is purpose (for example, firmly changing the trade name " ス ミ サ Application ス イ (Japanese) R greenhouse " that agriculture goods, materials and equipments limited company produces).This watering pipeline 170, as shown in figure 21, be set at vinyl plastics film greenhouse 171 such as central portion, like this, hold the watering utensil need not resembling in the past and vinyl plastics film greenhouse 171 in, move, just can carry out watering of necessity at short notice.
In above-mentioned watering pipeline 170, in order to improve the uniformity of watering, the combinatorial problem at the elevation angle of the aperture of water sprayering hole and water sprayering hole is scrutinized.
Here, in watering pipeline 170 in the past, when wearing water sprayering hole, employing is bored a hole facing to the raw material plate of flat, from vertical direction perforation, employing and is shone the method that wears water sprayering hole with pin or laser.Below, this method for punching is called vertical perforation.
By the water sprayering hole that wears like this, water relies on hydraulic pressure in the direction perpendicular to the pipe inner face tangent line in the watering pipeline 170 of tubulose, that is, disperse on the radial direction in tubular pipeline.
The watering stream of such water sprayering hole is temporarily kept bar-shaped watering stream after spraying from water sprayering hole, subsequently because of air drag can begin to be separated into fine liquid drops gradually, and form the dispersion of drop sharp from a certain moment beginning.
But,, exist the problem of following watering height and the problem at the intensity peak of watering for above-mentioned watering pipeline in the past.
That is, as the problem of watering height, with technology in the past, particularly, water sprayering hole is arranged on high position, the elevation angle, for example in order near watering pipeline, to sprinkle water, often adopt behind the height that watering is sprayed onto about 3m the method that drop is nearby fallen to watering pipeline.This be because, as previously mentioned, flow from the watering that the water sprayering hole that is used for watering pipeline in the past ejects, have and after spraying, temporarily keep bar-shaped watering stream, gradually begin to be separated into fine liquid drops because of air drag subsequently, and, therefore need before disperseing, bar-shaped current make its rising from the characteristic that a certain moment begins to disperse.
Owing to adopt this method, make near the watering watering pipeline become possibility, but shown in Figure 22 (a) and Figure 22 (b), when the height till vinyl plastics film greenhouse 171 ceilings is not enough, and as shown in figure 23, cooling is set with yarn 172 for the temperature of ethene suppressing plastic foil greenhouse 171 inside, Bao Bushi promptly is set, owing to can not upwards be sprayed onto the height that needs to watering, appearance can not be near watering pipeline sufficient problem of watering.
About this point, have and set forr a short time than other water sprayering hole by spraying to flexible pipe water sprayering hole nearby, flow is reduced, the method of the peak value of intensity thereby inhibition is watered is (for example, with reference to " day disclosure utility model communique " real fair 3-26376 communique " (on August 30th, 1986 is open) ".
In addition, for example, also have a kind of part that on thin plate perforate wall, is formed with to cover the water sprayering hole 30 inclined plane 31, as shown in figure 25 (for example, with reference to " Japanese publication communique " spy opens the 2000-176319 communique " (on June 27th, 2000 is open) ") that the direction of dispersing of the water under the hydraulic pressure effect makes it to change.
Near water sprayering hole highly low and that can sprinkle water watering pipeline so just obtains sprinkling water.In addition, another problem that watering in the past exists with pipeline is the peak value of the relevant intensity of watering, i.e. the homogeneity question that watering distributes.
According to above-mentioned in the past method as shown in figure 21, by high elevation angle water sprayering hole to aspect the watering pipeline watering nearby, the tendency that the distribution that watering occurs concentrates on narrow range, relatively there is grow in the intensity of watering (mm/hr) and other watering zone.As putting relevant countermeasure therewith, above-mentioned " day disclosure utility model communique " real fair 3-26376 communique " (on August 30th, 1986 is open) " though in methodical expression, but, there is the tendency that water sprayering hole is more little, the watering scope is narrow more for the watering at the high elevation angle.Therefore, for guaranteeing uniformity, need more water sprayering hole to watering pipeline watering nearby.Like this,, then be difficult to add uniform hydraulic pressure in the upstream side and the downstream of water spray hose if on watering pipeline, form many water sprayering holes, therefore, the problem that can not extend with regard to the length that has produced water spray hose, the i.e. problem of long size.
In addition, owing to adopt the water sprayering hole 30 (with reference to Figure 25) of record in " Japanese publication communique " spy opens the 2000-176319 communique " (on June 27th, 2000 is open) ", make the watering of carrying out broader region by each water sprayering hole become possibility, but people expect and can sprinkle water highly uniformly with lower watering in recent years.Specifically, exactly the expectation situation that obtains under the state of implementing the tunnel covering about highly about 60cm, sprinkling water etc. etc., with low-down watering highly also can uniform sprinkling water sprayering hole.When so strictness restriction is highly done in watering, exist to be difficult to utilize the watering pipeline that forms water sprayering hole 30 to sprinkle water, particularly exist the problem that is difficult to sprinkling water uniformly near the watering pipeline uniformly.
Summary of the invention
The present invention is in order to solve the above problems, purpose is to provide and can and guarantees to obtain in the nearby position of sprinkler or watering pipeline with low watering height sprinkler, the manufacture method of sprinkler, the watering pipeline of the water sprayering hole of the suitable intensity of watering to the uniform sprinkling of broader region more, the manufacture method of watering pipeline, and mist cooling means.
Sprinkler of the present invention is the sprinkler that a plurality of water sprayering holes is set for addressing the above problem, and it is characterized in that, in a side that relies on hydraulic pressure to make water to disperse, have and can make its center line water sprayering hole that form, adjacent crossingly.
According to foregoing invention, the water that disperses from adjacent water sprayering hole relies on hydraulic pressure to disperse after discharging from sprinkler, makes the current of mutual bump disperse, disperse.Because this clashes into mutually, not only weaken the current of the water that disperses, the i.e. surge pressure of current that disperses, and can make the water droplet micronize, form vaporific fine water droplets.
Promptly, the sprinkler of the nozzle of watering usefulness in the past and watering pipeline etc., the general perforate wall relative thin plate cross section perpendicular that all has a water sprayering hole on the thin plate, present the frustum of a cone of bottom width or the water sprayering hole of the thin frustum of a cone before the surface presents to the surface, that is, have usually relatively thin plate and present the water sprayering hole that vertical cylinder shape, apparent surface present bottom width or preceding thin circular cone shape.And because the water that disperses away from adjacent water sprayering hole mutual bump does not take place, is bar-shaped to the extended line of radial direction and disperses, therefore, water can be done remote watering according to hydraulic pressure.
Therefore, for afield the sprinkler of allowing to sprinkle water in the nearby watering of sprinkler, make it to disperse upward once be necessary, and need to improve the watering height.In addition, even disperse upward, still can not be in the broad regions watering nearby of sprinkler.
To this, sprinkler of the present invention is in a side that relies on hydraulic pressure to make water to disperse, have and can make its center line water sprayering hole that form, adjacent crossingly.Therefore, the direction of the current that disperse that disperse out from sprinkler by hydraulic pressure changes owing to clash into the current that disperse from adjacent water sprayering hole.In addition, the imposing manner of current because such bump can suppress to disperse makes highly attenuating of watering distance and watering.
In addition, because such bump, cause dispersing everywhere with the bar-shaped water that disperses, the water droplet of the water that disperses by micronize, become vaporific fine water droplets, expanded in watering pipeline watering zone nearby.Therefore, do not need to resemble and disperse once upward the watering pipeline in the past, so can lower the watering height.
Its result can provide the sprinkler that need not improve the watering height, can carry out uniform sprinkling in the nearby position of sprinkler to more wide zone.
Sprinkler of the present invention, the diameter (R) of the perforation excircle that size is little in the adjacent water sprayering hole are below the 2.0mm, more than the 0.05mm.
Sprinkler of the present invention, the distance of adjacent water sprayering hole (D) are below the 20mm, more than the 0mm.
Sprinkler of the present invention, the above-mentioned center line in the adjacent water sprayering hole and above-mentioned water is flown out angle (X) that the face of side forms is below 80 °, more than 20 °.
Again, sprinkler of the present invention can be used as the thin plate-like object formation.Here, gauge of sheet can be got about 0.1mm～4mm, and serves as better with the thickness of 0.2mm～1mm.In addition, the material of thin plate is not limited to resin, also can with metal and rubber.In addition, thin plate not necessarily leaves no choice but make big part, also can make the such smallclothes of nozzle that use on sprayer front end etc.
In addition, though can be done so that its center line intersects, the number of adjacent water sprayering hole be a plurality of, be not particularly limited, be preferably made 2.If adjacent water sprayering hole is more than 3, for the center line that makes them meet at a bit, very high to the requirement of precision when forming water sprayering hole, and when making 2 because in the same plane, can realize making center line to meet at a bit easily.Therefore, sprinkler of the present invention, the quantity of adjacent water sprayering hole is even number.
In addition, the manufacture method of sprinkler of the present invention is characterized in that: it is the manufacture method with sprinkler of a plurality of water sprayering holes, in a side that relies on hydraulic pressure to make water to disperse, can make its center line wear adjacent water sprayering hole crossingly.
According to above-mentioned invention, above-mentioned sprinkler, can by in the side that relies on hydraulic pressure to make water to disperse, can make its center line wear adjacent water sprayering hole to make crossingly.
Like this, can provide the manufacture method that to carry out in the nearby position of sprinkler to than the sprinkler of the uniform sprinkling of broad regions.
Watering pipeline of the present invention for solving the above problems, is characterized in that: it is the pipeline with the usefulness of watering of a plurality of water sprayering holes, in a side that relies on hydraulic pressure to make water to disperse, have and can make its center line water sprayering hole that form, adjacent crossingly.
That is, as in the past, utilize towards the water sprayering hole that relies on hydraulic pressure that water is formed to the surface that radial direction disperses, the water that disperses out from adjacent water sprayering hole does not clash into, disperses with bar-shaped on the extended line of radial direction.Therefore, can water be sprinkled water at a distance according to hydraulic pressure.
Therefore, for afield the sprinkler of allowing to sprinkle water in the nearby watering of sprinkler, make it to disperse upward once be necessary, and need to improve the watering height.In addition, even disperse upward, can not be in the broad regions watering nearby of sprinkler.
To this, watering pipeline of the present invention is in a side that relies on hydraulic pressure to make water to disperse, have and can make its center line water sprayering hole that form, adjacent crossingly.Therefore, by the water that hydraulic pressure disperses out in the side of dispersing, the water bump with dispersing out from adjacent water sprayering hole changes direction.That is, the current that disperse of the water that disperses that disperses out from adjacent water sprayering hole by such bump, can suppress the imposing manner of water nearby the clashing into of watering pipeline.Therefore, by such inhibition, can lower the watering distance and the watering height of the water that disperses.
Again, because the inhibitory action that such bump forms, cause dispersing, make disperse aqueous dispersion, watering zone enlarge with the bar-shaped water that disperses that the disperses fine water droplets of dispersing everywhere, nebulize.Like this, can sprinkle water equably in watering pipeline broader region nearby.
This result, making becomes possibility to the uniform watering of broad regions more, and can provide and have with low watering height at the watering pipeline watering pipeline of the water sprayering hole of the suitable intensity of watering of position assurance nearby.
Watering pipeline of the present invention, for addressing the above problem, it is characterized in that: be pipeline with the usefulness of watering of a plurality of water sprayering holes, when the hydraulic pressure with 0.2MPa disperses water, in a side that relies on hydraulic pressure to make water to disperse, have and to make that form, the adjacent water sprayering hole of the water knock against each other that disperses away with hitting from the pipeline of the usefulness of watering.
According to above-mentioned invention, can utilize the pressure of supply water about normally used 0.2MPa during operation that waters in facility cultivation, make current nearby the clashing into of dispersing of the water that disperses away from adjacent water sprayering hole at watering pipeline.
Therefore, do not use in order to make water disperse and have special device, utilize with the obtainable such hydraulic pressure of general running water, the current that disperse of the water that disperses out from adjacent water sprayering hole being clashed near watering pipeline reliably in order to the power that obtains high hydraulic pressure from water sprayering hole.
This result, making becomes possibility to the uniform watering of broad regions more, and can provide and have with low watering height at the watering pipeline watering pipeline of the water sprayering hole of the suitable intensity of watering of position assurance nearby.
In addition, in the operation of watering of facility cultivation, also adopt supply pressure sometimes, specifically adopt supply pressure in 0.05MPa～0.2MPa scope sometimes less than 0.2MPa.Therefore, above-mentioned adjacent water sprayering hole, if when the hydraulic pressure with 0.05MPa disperses water, in a side that relies on hydraulic pressure to make water to disperse from the pipeline of the usefulness of watering, water sprayering hole that the water knock against each other that disperses is away formed with hitting, then better.
Above-mentioned adjacent water sprayering hole preferably makes the water under the hydraulic pressure effect all be formed at the perforate wall to the inclined plane that the direction of dispersing of radial direction changes.
By above-mentioned formation, water relies on hydraulic pressure when watering pipeline disperses, and the direction of water is covered a part by this inclined plane and changed.In addition, at this moment, the imposing manner of water is suppressed by this inclined plane.Therefore, by this inhibition, watering distance and watering height are further lowered.
In addition, by the inhibition that causes by this inclined plane, make and disperse, make aqueous dispersion, watering zone to enlarge everywhere with the bar-shaped water that disperses.
This result, can be provided at sprinkler nearby position, can carry out the sprinkler of uniform sprinkling to broad regions more with lower watering height.
Above-mentioned adjacent water sprayering hole, if the thickness that is the pipeline on the conduit section of flat state be made as L, from being made as H to the height of the intersection point of the center line of above-mentioned adjacent water sprayering hole with the face of the pipeline of the anti-face side of side of sprinkling water, preferably satisfy the relation of following formula:
0.5×L＜H＜L+50mm…(1)
By above-mentioned formation, can provide to make the water that disperses out from adjacent water sprayering hole near watering pipeline, clash into, can carry out to broad regions the sprinkler of uniform sprinkling reliably mutually in the nearby position of sprinkler.
Watering pipeline of the present invention also can be to have the member that combines with above-mentioned adjacent water sprayering hole, with the water sprayering hole that forms at a side that relies on hydraulic pressure to make water to disperse, the center line that do not make its center line and other water sprayering hole crossingly.
Sprinkler of the present invention, the diameter (R) of the perforation excircle that size is little in the adjacent water sprayering hole are below the 2.0mm, more than the 0.05mm.
Sprinkler of the present invention, the distance of adjacent water sprayering hole (D) are below the 20mm, more than the 0mm.
Sprinkler of the present invention, the above-mentioned center line in the adjacent water sprayering hole and above-mentioned water is flown out angle (X) that the face of side forms is below 80 °, more than 20 °.
And in sprinkler of the present invention, the quantity of adjacent water sprayering hole is even number.
Like this, can utilize above-mentioned adjacent water sprayering hole, also can utilize the center line that does not make its center line and other water sprayering hole water sprayering hole that form, in the past to sprinkle water crossingly in the position of leaving watering pipeline to watering near the watering pipeline.Therefore, can guarantee wide watering zone by wearing the water sprayering hole that lacks than quantity in the past.
Again, as above-mentioned water sprayering hole in the past, can enumerate the water that makes under the hydraulic pressure effect and be formed at the example of perforate wall to the inclined plane that the direction of dispersing of radial direction changes, and perpendicular to making water rely on the example etc. of perforate wall that hydraulic pressure disperses to radial direction or the frustum face that forms bottom width towards the surface.
The manufacture method of the pipeline of the usefulness of watering of the present invention, in order to solve the above problems, it is characterized in that: this is the manufacture method with watering pipeline of a plurality of water sprayering holes, by the pipeline that is flat state in the watering pipeline is worn water sprayering hole from tilted direction, in a side that relies on hydraulic pressure to make water to disperse, can make its center line form adjacent water sprayering hole crossingly.
According to above-mentioned invention, when watering pipeline forms water sprayering hole, the pipeline that is flat state in the watering pipeline is worn the tubular opening from tilted direction.As the tubular opening, generally be cylindric, but be not limited thereto that for example polygonal tubular is good again.
Like this, in a side that relies on hydraulic pressure to make water to disperse, can easily form and can make its center line water sprayering hole that form, adjacent crossingly.
This result, can provide can be to the uniform watering of broad regions more, and can nearby can guarantee the manufacture method of watering pipeline of the water sprayering hole of the suitable intensity of watering in the position at watering pipeline with low watering height.
The manufacture method of above-mentioned watering pipeline preferably wears above-mentioned water sprayering hole by irradiating laser.
Like this, can easily form precision height, reliable and water sprayering hole that expect easily.
Adopt watering pipeline of the present invention also can carry out the mist cooling.Watering pipeline of the present invention possesses the mist cooling device of power sprayer in the past than it, because simple structure thereby cost are low.So, can realize that the mist that in the past could realize with very high cost cools off with dog-cheap expense.Mist cooling means of the present invention is characterized in that; Employing has a plurality of water sprayering holes, and adjacent water sprayering hole is arranged to its center line and is carried out at the watering pipeline that a side that relies on hydraulic pressure that water is flown out intersects, or, employing has a plurality of water sprayering holes, and when adjacent water sprayering hole is arranged in hydraulic pressure with 0.2MPa water is flown out, a side that relies on hydraulic pressure that water is flown out from watering pipeline make the water that flies out mutually the watering pipeline of collision carry out.
Watering pipeline of the present invention can adopt and lay watering pipeline to such an extent that contact, implement the sprinkling method of sprinkling water with culture medium for cultivating surface, and at this moment, for example, the direction of the water that disperses from above-mentioned adjacent water sprayering hole preferably can more down be sprinkled water than horizontal direction.
Like this, even under the condition that sprinkle water height and watering width is had strict especially restriction, also can carry out even and sufficient watering in the scope of expecting.
That is because the direction ratio horizontal direction of the water that disperses that disperses from above-mentioned water sprayering hole below more, with the direction of the water that disperses towards the horizontal direction top relatively, the watering of the water that disperses height, watering width all can suppress.In addition, because the pipeline laying of will sprinkle water must implement contiguously to sprinkle water with the culture medium for cultivating surface, can prevent from that the water that disperses out is attached to do on the object.Therefore, as for resembling the sprinkling method of making object that flowers class etc. is abstained from airborne fine water droplets of swimming, be fit closely.
Like this, according to the sprinkling method that uses watering pipeline of the present invention, even under the condition that sprinkle water height and watering width is had strict restriction, also can sprinkle water equably in desired region.
About other purpose of the present invention, feature, and advantage, in following content, be described in detail.In addition, benefit of the present invention is below with reference to will be appreciated that in the description of the drawings.

Embodiment
As one of example of the present invention, be that the basis is explained as follows with Fig. 1 and Fig. 2.
Fig. 1, being the figure of one of the example of expression sprinkler of the present invention, is expression because the water knock against each other that disperses that disperses out from water sprayering hole has hit, promoted the miniaturization of the water droplet that hydraulic pressure causes and made a fluid stream of the water that disperses, i.e. the disperse cutaway view of the principle that the surge pressure of current weakens.Shown in figure, the sprinkler 1 of this example comprises the water sprayering hole 10A10B that a group is adjacent, and this water sprayering hole 10A10B perforation centre line L A and LB separately intersects at and relying on hydraulic pressure P to make the disperse intersection point C of side of water.
For this reason, the water that disperses out from this water sprayering hole 10A10B respectively disperses water at the hydraulic pressure P that relies on sprinkler 1 and clashes near the intersection point C of side, owing to this bump, promote the miniaturization of the water that disperses out from water sprayering hole 10A10B, can weaken the surge pressure of the current that disperse simultaneously.
That is because the water that disperses that disperses out from water sprayering hole 10A10B is nearby the clashing into of sprinkler 1, shown in dashed lines among Fig. 1 like that, near the thin plate of formation sprinkler 1, can sprinkle water in very wide scope.
Because the water that disperses is expanded, can weaken the surge pressure of the water that disperses in broad range again.Therefore, can prevent to cause an one of sprinkling water regional or form depression or the phenomenon in formation water route because of the influence of surge pressure.In addition, do not distinguish water sprayering hole 10A10B, when handling as the water sprayering hole of a group that gathers, below, just only be recited as water sprayering hole 10.
In addition, on the perforate wall 11A11B of water sprayering hole 10A10B, formation makes the inclined plane 12A12B that the direction of dispersing of the water under the hydraulic pressure effect changes respectively.Therefore, when water will rely on hydraulic pressure to disperse, the direction of water was hidden a part by this inclined plane 12A12B and changes, and the imposing manner of water is suppressed.Owing to dispersing water before above-mentioned intersection point C clashes into, formed covering, so the inhibition of the distance of sprinkling water and the miniaturization of water droplet all can realize certainly by this inclined plane 12A12B.Therefore, near the thin plate that constitutes sprinkler 1, can sprinkle water in very broad scope more reliably.
Fig. 2, be used in the sprinkler of key diagram 1, the cutaway view of the shape of position that the center line of adjacent water sprayering hole intersects and the water sprayering hole seen from all directions.At first, based on Fig. 2, the explanation water sprayering hole 10 shape.Shown in figure, the water sprayering hole 10A10B of the sprinkler 1 of this example, shape is identical, the direction of just boring a hole difference.More specifically say, from above and below when seeing, its periphery circle ovalize is when the perforation direction is seen, its periphery circle is rounded.Therefore, the center line of the water sprayering hole 10A10B of this example (perforation center line) LALB, the straight line at the center of saying that be exactly to link the periphery circle when the perforation direction is seen.
In addition, as shown in Figure 2, the ellipse of the periphery circle when the watering side of sprinkler 1 or its opposition side are seen water sprayering hole 10A10B, focus nearly all is positioned on the straight line.That is, above-mentioned ellipse presents its major axis and almost is positioned at shape on the straight line.Therefore, can make the water that disperses nearby produce the high efficiency bump on the surface of sprinkler 1 from water sprayering hole 10A10B.
Then, based on Fig. 2, the distance of the intersection point C of the center line from sprinkler 1 to water sprayering hole 10A and 10B is described.Shown in figure, the distance from sprinkler 1 to intersection point C is not according to the watering side surface of the thin plate that constitutes sprinkler 1 but stipulate according to the distance H of starting at from its opposite side surfaces (mm).This distance H, water sprayering hole 10A10B, if the gauge of sheet on sprinkler 1 section that is flat state is made as L (mm), preferably the relation of following formula is satisfied:
0.5×L(mm)＜H(mm)＜L(mm)+50(mm) …(1)
Like this, can make the water that disperses from water sprayering hole 10A10B nearby clash into, make its surge pressure to weaken and in broad range, sprinkle water reliably on the surface of sprinkler 1.
Again, shown in above-mentioned formula (1), the H value, as long as greater than half of gauge of sheet L, also can be in the water sprayering hole 10 of the thin plate inside of sprinkler 1, the water that disperses from water sprayering hole 10A10B is clashed into.
In addition, the distance H from sprinkler 1 to intersection point C, as satisfy following formula (2), then better; As satisfy formula (3), then also will get well.
1.0×L(mm)＜H(mm)＜L(mm)+20(mm) …(2)
1.5×L(mm)＜H(mm)＜L(mm)+10(mm) …(3)
As shown in Figure 2, use the perforation periphery circle of the water sprayering hole 10A10B that sees from anti-perforation direction, promptly with the perforation periphery circle of the perforation direction of the opposition side of the watering side of thin plate, promptly wherein the little person's of size perforation periphery diameter of a circle R represents the aperture of water sprayering hole 10A10B.The diameter R of water sprayering hole 10A10B, R preferably are taken as below the 2.0mm, more than the 0.05mm, but are not limited thereto, and can adjust according to gauge of sheet and feed pressure etc.
As shown in Figure 2, use distance D position that the face with the watering side of thin plate intersects, its center line LA and centre line L B to represent the distance of water sprayering hole 10A and water sprayering hole 10B.The distance D of water sprayering hole 10A and water sprayering hole 10B preferably is taken as below the 20mm, more than the 0mm, but is not limited thereto, and can adjust according to gauge of sheet and feed pressure etc.
If the angle X that forms between the face with the watering side of its center line LA and centre line L B and thin plate represents the perforation direction of water sprayering hole 10A and water sprayering hole 10B, X preferably is taken as below 30 °, better more than 20 °.In addition, X be preferably in below 80 °, better more than 60 °
By forming water sprayering hole 10A10B, making above-mentioned H, D, R, X satisfy above-mentioned condition, just can make the water that disperses from water sprayering hole 10A10B near the surface of sprinkler 1, clash into, make its surge pressure to weaken more reliably and in broad range, sprinkle water.
For another example of the present invention, make the following instructions with Fig. 3～Figure 11 (c).In addition, in this example, the watering pipeline as sprinkler is described, but sprinkler being not limited thereto, for example, also can be the sprinkler of nozzle etc. that is used for the watering usefulness of sprayer.In addition, for ease of explanation,, be omitted with going up same symbol, its explanation for having the member of said function with the member shown in the accompanying drawing of above-mentioned example.
In this example, the situation that sprinkler of the present invention is implemented as watering pipeline is described.Fig. 3 is illustrated in the pipeline of flat state, makes its center line form the state of water sprayering hole 10 in the watering side crossingly.On pipeline, form water sprayering hole 10, be the method for the adjacent water sprayering hole 10A10B of a group (a pair of), be not particularly limited, for example can list the method that adopts laser.
Then, for configuration example, describe according to Fig. 4 (a) and Fig. 4 (b), Fig. 5 (a) and Fig. 5 (b) as the adjacent water sprayering hole of the watering pipeline of the sprinkler of this example.
The watering pipeline 2 of this example shown in Fig. 4 (a), all be 2 thin plates that the thermoplasticity film of synthetic resin by the polyethylene of thin thickness etc. is constituted overlap, again to processing such as the circumference of the mutual width of the thin plate of these coincidences seal, make sealing state, form the member of tubulose with a pair of ear shape portion 2323.
This gauge of sheet is for example got about 0.5mm, but not necessarily is limited to this, and is also applicable for the thickness about 0.1mm～3.0mm.
Like this, watering pipeline 2, when watering during water flowing, owing to hydraulic pressure expands, becoming such as diameter is tubulose about 30mm～40mm, becomes flat when not water flowing.In addition, the watering pipeline 2 of this example also not necessarily needs ear shape portion 2323.In addition, the diameter of watering pipeline 2 is not particularly limited, and can suitably set according to the water yield of being supplied with by watering pipeline 2 and hydraulic pressure etc.
In addition, shown in Fig. 4 (a), water sprayering hole 10 can dispose adjacent water sprayering hole 10A and water sprayering hole 10B substantially abreast with pipe lengths.In addition, water sprayering hole 10 also can be done substantially uniformly-spaced configuration on pipe lengths.Like this, water sprayering hole 10 is by wearing formation with water sprayering hole 10A and water sprayering hole 10B as a unit.
Above-mentioned watering pipeline 2, it repeats withstand voltage fatigue strength superior performance, simultaneously, has expansibility resistance, warm tolerance, cold resistance, anti-drawing crack and resistance to impact.In addition, though not shown in watering pipeline 2 also can be in its surface, form a plurality of reinforcements that extend along its length.Like this, watering pipeline 2 is not easy to bend in the time of can making water flowing.
This watering pipeline 2 was connected with not shown pump in when watering, utilized this pump to add such as the hydraulic pressure about 0.2MPa.And, from the water that disperses of adjacent water sprayering hole 10A10B watering pipeline 2, above-mentioned, nearby clashing at the intersection point C of centre line L ALB.
Above-mentioned watering pipeline 2 is in a tubular form the time, and a series of water sprayering hole 10 wears along its length in accordance with regulations at interval.In addition, these water sprayering holes 10, in Fig. 4 (a) and Fig. 4 (b), the 1st quadrant of tubular sections, length direction along watering pipeline 1 wears into one (row) in accordance with regulations at interval, but be not limited thereto, in the 1st quadrant of section circle, also can wear into many (multiple rows) in accordance with regulations at interval along the length direction of watering pipeline 1.
Also have, not only at the 1st quadrant of tubular sections, also can form water sprayering hole 10 in one or more ground at the 2nd quadrant.In addition, the interval of these water sprayering holes 10, the intervals of the plantling branch that consideration is cultivated etc. are set in accordance with regulations at interval.
In addition, the water sprayering hole 10A10B of the water sprayering hole 10 on the watering pipeline 2 of this example, when making watering pipeline 2, be not to plane raw material thin plate, in the stage that ear shape portion 2323 is not sealed, wear via the angle that is not the perforation angle X (with reference to Fig. 2) of vertical direction.About this perforation angle X, it is applicatory getting 20～80 degree, and expected value is 30～60 degree.Like this, make the watering distance and the watering range of water.
This water sprayering hole 10A10B wears, in this example, for example can use laser irradiation to carry out.But, be not limited thereto, for example use punch press and perforation to wear also passable with pin.
Utilize this water sprayering hole 10A10B, as shown in Figure 2, from the surperficial incident laser of thin plate, and connect to the inside side of thin plate and wear, simultaneously, at its perforate wall 11A11B, have the inclined plane 12A12B and the opposite face that toward the inside side of thin plate the aperture are dwindled from the surface of thin plate.
Promptly, water sprayering hole 10, for the pipeline that is flat state in the watering pipeline 2, by tilted direction wear from pipe surface to the anterior shape that attenuates in pipeline the inside, such as the opening of circular cone scalariform, the water the hydraulic pressure effect under is formed on the perforate wall 11A11B towards the inclined plane 12A12B of the direction variation of dispersing of radial direction.
In detail, water sprayering hole 10A10B, the laser of the section circle by not shown convex lens, via perforation angle X from the face side oblique incidence of thin plate, connect thin plate.Therefore, as shown in Figure 2, big than the inside side in face side, its aperture of thin plate.
Again, why can wear from the opening of pipe surface from tilted direction like this, can think, owing to the energy that by convex lens mainly is laser is the cause that decays gradually to the anterior circular cone scalariform that attenuates in pipeline the inside.
Therefore, can be clear that also that the inclined plane 12A12B of plumb line side has than perforation angle X big angle of inclination, and the taper surface relative, have little angle of inclination than perforation angle X with it from Fig. 2.
In addition, thus, when from thin plate top when vertical direction is provided with water sprayering hole 10A10B, the part of the inside water sprayering hole of the inboard of thin plate, can hide its part even hide the hole by inclined plane 12A12B.
In addition, in above-mentioned watering pipeline 2, the thin state of laser is connected thin plate, but be not limited thereto, laser also can be the rounded pencil of parallel lines of section.That is,,, also can form the water that makes the hydraulic pressure effect under is formed at perforate wall 11A11B towards the inclined plane 12A12B of the direction variation of dispersing of radial direction water sprayering hole owing to wear such as the tubular opening from tilted direction for the pipeline of the flat state of watering pipeline 2.Because perforation like this can be by carrying out such as the energy that increases laser.
Fig. 4 (b), the state of the water sprayering hole when being watering pipeline 2 water flowings of presentation graphs 4 (a), along the cutaway view of A-A ' line direction.Shown in figure, when watering pipeline 2 water flowings, respectively from water sprayering hole 10A and 10B, being in substantially parallel relationship to the water that disperses that pipe lengths is dispersed, near the intersection point C of the centre line L A of water sprayering hole 10A10B and LB, water clashes into.
Constitute the quantity of water sprayering hole 10A10B water sprayering hole 10, that a group is adjacent of the watering pipeline 2 of this example, with even number for well, be 2 then especially good.If the water sprayering hole by the adjacent odd number of a group constitutes water sprayering hole 10, then worn porose perforation center line should concentrate entirely on 1 point.If it is just destroyed that not like this, a fluid stream of the water that disperses of the water sprayering hole of adjacent odd number does not concentrate on the balance of 1 point, bump.Therefore, just become and the variform result of watering who designs.
In addition, when the adjacent water sprayering hole by the odd number more than 3 constitutes water sprayering hole 10, also has the another one difficulty.Here it is, in order to make the current that disperse (discharge current) concentrate on 1 point from adjacent water sprayering hole, not only require the intersection point of the perforation center line of each water sprayering hole to concentrate, and require aperture, hole shape, the hydraulic pressure etc. that is added in adjacent each water sprayering hole is identical, is unusual difficulties but satisfy these conditions fully.
Therefore, as the watering pipeline 2 of this example, the water sprayering hole 10 that its center line is formed crossingly preferably is made of 2 water sprayering hole 10A10B.
Here, be example with water sprayering hole 10 such shown in Fig. 4 (b), that form by the X perforation, above-mentioned aperture, hole shape, the condition that is added in the hydraulic pressure etc. of each water sprayering hole are described.Water sprayering hole 10 is made of aperture and the identical water sprayering hole 10A10B of hole shape, therefore, supposes that water sprayering hole 10A is identical with water sprayering hole 10B in the inner anhydrous hydrostatic pressing when mobile of watering pipeline 2.
But, from the upstream side of the current of pipe interior downstream side, from the inboard of pipeline the water sprayering hole 10B of perforating laterally, with from the downstream upstream side, from the inboard of pipeline laterally the water sprayering hole 10A of perforating relatively, since the pressure of the influence of current, the water that disperses increase.That is, water sprayering hole 10A and water sprayering hole 10B, owing to the current with watering pipeline 2 inside are arranged in parallel, the pressure the when result causes water sprayering hole 10A with water sprayering hole 10B water to be dispersed is different.
That is, the influence of the kinetic energy that produces by the current of watering pipeline 2 inside, water sprayering hole 10A is different with water sprayering hole 10B.That is,, therefore, can think that the influence of the kinetic energy that produced by current does not exist because the direction of dispersing of the water that disperses that comes out from water sprayering hole 10A is reverse with the current in the watering pipeline 2.In addition, the direction of dispersing of the water that disperses that comes out from water sprayering hole 10B since with watering pipeline 2 in current in the same way, therefore, the kinetic energy that produces by current be on the occasion of, i.e. its effect makes the hydraulic pressure increase.
Here, the proportion of establishing above-mentioned water is 1, the speed of water is that V (m/s), acceleration of gravity are g (m/s
2), then the kinetic energy that is produced by above-mentioned current can be expressed as V
2/ 2g (gm).
Therefore, the full water pressure that water sprayering hole 10A10B works respectively, water sprayering hole 10B side is bigger than water sprayering hole 10A side.This has just become to hinder makes near 1 the crossing key factor of water intersection point C of discharging from water sprayering hole 10A10B.
In addition, the watering pipeline 2 of this example, the perforation centre line L ALB of 2 water sprayering hole 10A10B that it is paired is in the same plane, can guarantee to become the intersection of a pair of current that disperse of least unit.In addition, paired water sprayering hole 10A10B since its aperture, shape identical, have symmetric relation, so balance is also good.
The watering pipeline 2 of this example forms even number (2) water sprayering hole 10A10B, the intersection point C of its center line LALB, be positioned at watering pipeline 2 the surface near.That is, the centre line L B of the centre line L A of water sprayering hole 10A and water sprayering hole 10B is positioned at same plane, in nearby intersecting of the surface of watering pipeline.Therefore, because how much difference appears in the flowing of the water of above-mentioned watering pipeline 2 inside, the hydraulic pressure that is added to the water that disperses by water sprayering hole 10A10B, this is for making water nearby the clashing into, weakening surge pressure and water is disperseed in broad range, the big influence of unlikely substantially generation at watering pipeline 2 of dispersing.
For this reason, constitute the structure of the even number assortment of water sprayering hole by the even number water sprayering hole, also can be on same plane with the centreline configuration of paired water sprayering hole, as the structure of the odd number assortment that forms by the odd number water sprayering hole, not necessarily need to make all perforation center lines of the water sprayering hole that constitutes water sprayering hole to concentrate on 1 point.
In addition, as relevant water sprayering hole 10 current that disperse (discharge current) nearby illustrate shown in Figure 1, the intersection point C of the center line of boring a hole is also not necessarily consistent with the rum point of the current of representing with the arrow of with dashed lines among the figure that disperse.This can think, since resemble watering pipeline 2, when not too thick thin plate (thin plate of the about 0.2mm～1.0mm of thickness) goes up that tiltedly perforation forms water sprayering hole 10, can not fully guarantee to be enough to make disperse the direction of current complete with the consistent perforation length (length of inclined plane 12A12B) of center line of boring a hole.
Like this, can think, only on such flat material such as above-mentioned thin plate, tiltedly bore a hole merely, during the thickness improper (more than the number mm) of thin plate and plate, be difficult to correctly control the direction of the current that disperse.Therefore, when sprinkler being used for the purposes that agricultural watering pipeline uses, when considering the thickness of the difficulty of perforation precision, manufacturing and necessary thin plate and plate, it is better than making the odd number assortment that adjacent water sprayering hole is made the even number assortment.
Fig. 5 (a) and Fig. 5 (b) are expression is arranged in parallel configuration water sprayering hole 10A10B to the conduit section direction figure.Shown in Fig. 5 (a), like that, the water sprayering hole that disposes water sprayering hole 10A10B is gathered, remembers and make water sprayering hole 20.In addition, the watering pipeline 3 shown in Fig. 5 (a), except that forming water sprayering hole 20 to replace the water sprayering hole 10, other watering pipelines 2 with above-mentioned explanation are identical, so relevant common item explanation is omitted.
Fig. 5 (b), be the water sprayering hole 20 during water flowing in the watering pipeline 3 of presentation graphs 5 (a) state, along the cutaway view of B-B ' line direction.Shown in figure, when watering pipeline 3 water flowings, respectively from water sprayering hole 10A10B, disperse with conduit section direction almost parallel ground, near the water that disperses the intersection point C of the centre line L A of water sprayering hole 10A10B and LB clashes into.
In addition, shown in figure, when the section direction of pipeline is disposed water sprayering hole 10A10B abreast, water sprayering hole 10A10B towards nearly all perpendicular to the direction of the current of the inside of watering pipeline 3.Therefore, the pressure of the water that disperses that comes out respectively from water sprayering hole 10A and 10B can not be subjected to the influence of the current of watering pipeline 3 inside.
In addition, in the above description, the configuration of water sprayering hole 10A and water sprayering hole 10B, the watering pipeline 2 of length direction that is parallel to pipeline and the watering pipeline 3 that is parallel to the section direction (perpendicular to the length direction of pipeline) of pipeline are described.But the configuration for as the water sprayering hole 10A and the water sprayering hole 10B of adjacent water sprayering hole is not limited to these, also can take watering pipeline 2 with the configuration of the centre of watering pipeline 3, promptly, the configuration of tiltedly length direction of pipeline being located.
Then, based on Fig. 6 (a)～Figure 11 (c), watering pipeline of one of example of sprinkler of the present invention and watering pipeline are in the past made comparisons.Fig. 6 (a)～Fig. 6 (c), be watering pipeline, and the cutaway view that constitutes of the summary of in the past watering pipeline of this example of expression, according to the order of Fig. 6 (a), Fig. 6 (b), Fig. 6 (c), expression form above-mentioned water sprayering hole 20 watering pipeline 3, have the water that makes the hydraulic pressure effect under to the inclined plane of the direction variation of dispersing of radial direction be formed at the water sprayering hole 30 of perforate wall watering pipeline in the past 4, have water under its center line and the hydraulic pressure effect to the watering pipeline in the past 5 of the direction of dispersing of radial direction water sprayering hole 50 unanimous on the whole.
Fig. 7, be in the past the watering pipeline 4 of expression as Fig. 6 (b) shown in water sprayering hole 30 near the stereogram of dispersity of the water that disperses.Shown in figure, near water sprayering hole 30, can be separated into vaporific via the flat current zone of several approximately cm of length.
Fig. 8 is the stereogram of the dispersity of the water that disperses near the water sprayering hole 20 of watering pipeline 3 of expression this example as Fig. 6 (a) shown in.Such as described above, water sprayering hole 20 is to be made of 2 adjacent water sprayering hole 10A10B, and these 2 water sprayering hole 10A10B should make its center line LALB hand over mutually at the utmost point intersection point C nearby of the watering side surface of watering pipeline 3 when forming.Like this, shown in figure, from 2 tunnel of water sprayering hole 20 water that disperses, near the utmost point intersection point C nearby of the watering side surface of watering pipeline 3 fierce bump takes place.Therefore, the water that disperses, not via the flat current zone of several approximately cm of length, from the utmost point of watering pipeline 3 nearby be dispersed into immediately vaporific, become vaporific fine water droplets.
Like this, as shown in Figure 8, watering pipeline 3 can be expanded its utmost point dispersion current zone nearby greatly, therefore, with 4 comparisons of watering pipeline in the past shown in Figure 7, especially can be in the watering that nearby carry out the broad range zone of watering pipeline.
Fig. 9 (a)～Fig. 9 (c) is the figure of the watering figure of each watering pipeline shown in the presentation graphs 6 (a)～(c).Shown in Fig. 9 (a), the watering pipeline 3 of this example has the water sprayering hole 20 that forms by the X perforation.Therefore, disperse the utmost point that initial point is positioned at watering pipeline 3 nearby, the water that disperses be dispersed in discharge after begin immediately.In addition, be used to the to disperse dispersion of water of the major part in the kinetic energy of the current that clash into immediately, disperse after the water one of dispersing is discharged, therefore, and as the very little vaporific fine water droplets of surge pressure, can be at the utmost point of watering pipeline nearby with the watering amplitude distribution of broadness.
Owing to can reduce watering height and watering distance significantly, in confined space, be suitable for very much uniform watering again.All the time can suppress the watering of distance water sprayering hole 20 height and watering distance to below 1/3 of water sprayering hole 50.Therefore,, can reduce the setting of watering height significantly, for example, can suppress the watering height, suppress the extremely degree of about 80cm of watering distance to about 60cm by using watering pipeline 3.
In addition, have shown in Fig. 9 (b), form the watering pipeline 4 of the water sprayering hole 30 of water sprayering hole by oblique perforation, by with water sprayering hole 30, make the water hydraulic pressure effect under to the direction variation of dispersing of radial direction, the dispersion of the water that can promote to disperse.
But, different from the water that disperses that water sprayering hole 30 is discharged with the water that disperses of discharging from water sprayering hole 20, can not disperse owing to the bump of many current that disperse.For this reason,, more farther from watering pipeline shown in figure than it watering pipeline 3 with the water sprayering hole 20 of being bored a hole by X to the distance of disperseing initial point, therefore, be difficult to nearby watering of the utmost point at watering pipeline 4.In addition, watering distance and watering big than watering pipeline 3 highly all.In addition, the watering water droplet of watering pipeline 4, thicker than the watering water droplet of the watering pipeline 3 of this example, the surge pressure of the water that disperses is also big.
Fig. 9 (c), expression has the watering pipeline 5 water sprayering hole 50, in the past of vertical perforation.The watering figure of the water sprayering hole 50 of the vertical perforation in the watering pipeline 5 in the past, shown in figure, after spraying, can keep bar-shaped watering stream soon from water sprayering hole 50, but because air drag makes fine liquid drops begin slowly to separate, get impatient constantly from certain begins the dispersion of drop sharply.
Like this, from watering pipeline 5, to the distance of the dispersion initial point of the current that disperse of discharging from the water sprayering hole 50 of vertical perforation, with the watering pipeline 3 of Fig. 9 (a) relatively, be very long.Therefore, the nearby watering at watering pipeline 5 is then very difficult.In addition, the watering water droplet of watering pipeline 5, is very thick at the watering water droplet comparison that produces with the watering pipeline 3 of this example, and the surge pressure of the water that disperses is also very big.
In addition, shown in Figure 10 (b) and Figure 10 (c), as the watering amount that offers plant etc., as seen the above intensity of watering of 5 of the desired value of Da Ti requirement (mm/hr), when forming watering by the water sprayering hole 30 of form in the past, be scope apart from the about 0.6m in the position of watering pipeline 4～about 1.8m, formed when sprinkling water, be scope by the water sprayering hole 50 of form in the past apart from the about 1.8m in the position of watering pipeline 5～about 3.2m.Like this, with in the past watering pipeline, special near it, can not carry out the watering of q.s.
To this, in Figure 10 (a) that the watering of the watering pipeline 3 of this example of expression distributes, be that the scope of 0～about 0.8m can be seen the intensity of watering more than 5 (mm/hr) in the position of distance watering pipeline 3.Like this owing to use the watering pipeline 3 of this example, can be difficult to especially realize in the past, to watering pipeline uniform sprinkling nearby.
Again, this intensity of watering (mm/hr) with highly representing per water that flew to spill how many capacity in 1 hour, adopts and the same computational methods of so-called rainfall, and unit is also identical.
In addition, when representing that as the plane watering in the watering pipeline 345 distributes, can resemble respectively and represent Figure 11 (a), Figure 11 (b), Figure 11 (c).Again, these waterings, to water sprayering hole 203050, all sprinkle water with the same watering elevation angle and same watering aperture, in detail, the watering elevation angle is 35 degree, the water sprayering hole diameter is 0.3mm.In addition, pressure of supply water is 0.2MPa altogether.In addition, here said above-mentioned water sprayering hole diameter 0.3mm, as shown in Figure 2, be meant the perforation periphery circle of the water sprayering hole 10A10B that sees from anti-perforation direction, promptly, justify, promptly refer to the little person's of its size perforation periphery diameter of a circle R with the perforation periphery of the perforation direction of the watering side opposition side of thin plate.In addition, in above-mentioned example, pressure of supply water is about 0.2MPa, and still, pressure of supply water is to do suitably to set according to the internal diameter of water sprayering hole, number etc.
According to distributing as can be known in the watering shown in Figure 11 (a)～Figure 11 (c), water sprayering hole 20 can be sprinkled water to nearby region more than water sprayering hole 3050, and in addition, the zone that can sprinkle water has nothing in common with each other.Like this, water sprayering hole 20 can realize to can not carry out with in the past water sprayering hole 3050 uniform sprinkling, sprinkle water with interior nearby region from the about 0.5m of watering pipeline.In addition, by with the water sprayering hole 20 of this example and in the past water sprayering hole 3050 combinations, can sprinkle water uniformly in broad range arbitrarily.
As previously mentioned, the watering pipeline of this example promptly uses a spot of water sprayering hole, and watering is evenly distributed, so, remove to wear a large amount of water sprayering holes not needing to resemble in the past, in order to be sprinkled water distribution uniformly.Like this, become in the time of can preventing to wear a large amount of water sprayering hole problem, in the uneven disadvantage of hydraulic pressure that connects water pump side water sprayering hole that forms and the water sprayering hole that is not connected the formation of water pump side.
That is, the watering pipeline of this example, nearby carries out uniform sprinkling at watering pipeline at water sprayering hole that can be by lacking than quantity in the past.For this reason, can prevent to produce inhomogeneous, the length of watering pipeline that can extend of above-mentioned hydraulic pressure, promptly, make the long size raising of watering pipeline.
In addition, the small-particleization by the watering water droplet can reduce the inertia energy that disperses, and promptly, sprinkle water, reduce the falling speed of particulate water droplet by utilizing vaporific particulate water droplet, can carry out very soft watering to crop.In addition, owing to can reduce the inertia energy that disperses, watering distance and watering are highly reduced.
The manufacture method of watering pipeline
The watering pipeline with a plurality of water sprayering holes of this example, wear water sprayering hole by pipeline from tilted direction to the flat state in the watering pipeline, can be in a side that relies on hydraulic pressure to make water to disperse, make its center line form adjacent water sprayering hole crossingly, that is, can bore a hole by X and make.
For example, manufacture method according to the watering pipeline 23 of this example, when on watering pipeline 23, forming water sprayering hole 1020, the pipeline of the flat state in the watering pipeline 23 is worn from pipe surface circular cone scalariform opening of shape carefully before the pipeline the inside is from tilted direction.In addition, the shape of water sprayering hole 1020 is not limited thereto, and is also passable such as polygonal awl scalariform.
Like this, can be easily in a side that relies on hydraulic pressure to make water to disperse, make its center line form adjacent water sprayering hole 10A10B crossingly.
This result can provide to have to make and to implement reliably that watering uniformly becomes possibility and the height that not too needs to sprinkle water, can guarantee the manufacture method of watering pipeline 23 of the water sprayering hole 1020 of the suitable intensity of watering in the nearby position of watering pipeline 23 to broader zone.
Here, according to the manufacture method of the watering pipeline 23 of this example, when on watering pipeline 23, forming water sprayering hole, also can wear the tubular opening from tilted direction to the pipeline of the flat state in the watering pipeline.In addition,, generally be cylindric, but be not limited thereto as the tubular opening, also passable such as polygonal tubular.
Like this, also can provide to have and make by bump and to implement that watering uniformly becomes possibility and the height that not too needs to sprinkle water, can guarantee the manufacture method of watering pipeline 23 of the water sprayering hole 1020 of the suitable intensity of watering in the nearby position of watering pipeline 23 to broader zone from the current that disperse of adjacent water sprayering hole 10A10B.
In addition, according to the manufacture method of the watering pipeline 23 of this example, when forming water sprayering hole 1020, wear by irradiating laser.Like this, but high accuracy, reliably and easily form the inclined plane 12 of expectation.
In addition, according to above-mentioned example, watering pipeline 23 is that 2 thin plates that the thermoplasticity film of synthetic resin by the polyethylene of thin thickness etc. constitutes overlap, the member after the processing such as the edge part of the mutual width of the thin plate that overlaps seals constituted again.
But, be not limited thereto, for example, can make the watering pipeline that constitutes by thick pipe of thickness or flexible pipe.This watering pipeline, for example, pipe or flexible pipe by thickness 0.2mm～4.0mm constitute, and can list thermoplastic resin, natural rubber, synthetic rubber or artificial rubber etc. such as polyethylene, polyvinyl chloride, poly-inferior vinyl chloride, polyamide, polyester etc. as material.These materials can suitably be selected for use alone or in combination.In addition, can make the additive that contains ultraviolet screener, antioxidant, colouring agent in these materials, reaches other as required.Even like this, also can obtain the watering situation same with above-mentioned watering pipeline 23.
For another example of the present invention, be that the basis makes the following instructions with Figure 12～Figure 16.In addition, for ease of explanation,, be omitted with going up same symbol, its explanation for the member of the member said function shown in the accompanying drawing that has with above-mentioned example.
At first, the position to the water sprayering hole that is formed at watering pipeline describes.Figure 12 cuts off the cutaway view of watering pipeline in the conduit section direction when being water flowing.Shown in figure, in the center O with watering pipeline is the X-axis and Y-axis of initial point, the X-axis with the 1st quadrant is the angle that calculates by counter clockwise rotation of the angle of the intersection point C of the starting point central shaft that arrives 2 adjacent water sprayering holes that constitute water sprayering hole 20, defines as the position of regulation water sprayering hole 20.In addition, this angle also can be the angle of the straight line that links above-mentioned initial point O and above-mentioned intersection point C with X-axis formation, in other words is that the X-axis with the 1st quadrant is the angle that starting point calculates.In addition, the situation of the water sprayering hole that constitutes at no above-mentioned intersection point C, by 1 hole, the position of stipulating water sprayering hole by the angle at the center of the watering side of the water sprayering hole that arrives no intersection point C.
Figure 13 (a) and Figure 13 (b) are the figure that represents the water sprayering hole after the X perforation and the water sprayering hole of tiltedly perforation are made up watering pipeline that be configured to, this example, and Figure 13 (a) represents stereogram, and Figure 13 (b) expression is along the cutaway view of C-C ' line direction.Shown in figure, the watering pipeline 6 of this example is that water sprayering hole described in the above-mentioned example 20 and water sprayering hole 30 are combined to form.
In addition, in the experiment of this example, as making water sprayering hole 20, adopt water sprayering hole 20 is disposed respectively in a straight line, water sprayering hole 30 is disposed in a straight line structure respectively with the positions of the positions of about 35 degree on the pipeline and about 145 degree with the positions of the positions of about 20 degree on the pipeline and about 160 degree with the watering pipeline 6 of water sprayering hole 30 combinations, shown in Figure 13 (a) and Figure 13 (b).
In addition, as Figure 13 (a) and shown in Figure 26,0.3mm is all got in the aperture of water sprayering hole 20, water sprayering hole 30, and 1 water sprayering hole 20 is equipped with 2 water sprayering holes 30.In addition, pressure of supply water is about 0.2MPa.
The watering of the water that the water sprayering hole 2030 from the watering pipeline 6 of such combination disperses out distributes, respectively shown in Figure 14 (a) and Figure 14 (b).
In addition, the distribution table of the water that disperses that will come out from all waterings of watering pipeline 6 is shown in Figure 14 (c).Shown in figure, all can guarantee the intensity of sprinkling water more uniformly to position at a distance in nearby position from watering pipeline 6.
Figure 15 (a) and Figure 15 (b) are the distribution maps of the flat state that distributes of the watering of each water sprayering hole of expression watering pipeline 6.The hatched example areas of Figure 15 (b) of other watering distribution that Figure 15 (a) that other watering distributes that expression is formed by water sprayering hole 20 and expression are formed by water sprayering hole 30 adds zone together, promptly is the zone of being sprinkled water by watering pipeline 6.Hence one can see that, and watering pipeline 6 especially can be sprinkled water in its broad regions nearby.
The watering situation of relevant above-mentioned watering pipeline 6 in vinyl plastics film greenhouse 100, as shown in figure 16, water sprayering hole 20 can be born the nearby position of watering pipeline 6, and water sprayering hole 30 can be born apart from watering pipeline 6 position far away slightly.
Here, therefore the miniaturization by water droplet and reduce surge pressure, water sprayering hole 20 greatly suppresses the to disperse distance of dispersing of water, can sprinkle water to the nearby position of watering pipeline 6 with low-down watering height.For this reason, as shown in figure 16, even carry out situation about covering such as the tunnel about highly about 60cm, disperse water also with carry out the members such as thin plate that the tunnel covers and contact, still can sprinkle water in the nearby position of watering pipeline 6.
Like this, the watering pipeline 6 of this example is even under the extremely strict condition of the restriction of relevant watering height, also can be easily be difficult to nearby watering of watering with in the past water sprayering hole.Also have, watering pipeline 6, be used for to carry out with crop the extermination of disease and insect pest, soil disinfection etc. be purpose, loose in the restricted quarter that to spill medicament also be suitable.
In addition, the combination of water sprayering hole is not limited to above-mentioned combination, and the water sprayering hole combination of water sprayering hole 1020 and water sprayering hole 3050 (with reference to Fig. 4 (a)～Fig. 6 (c)) and other modes in the past also can.
As previously mentioned, to the nearby watering of position of watering pipeline 6, undertaken by the water sprayering hole 20 that forms inclined plane 11, watering to the position of leaving watering pipeline 6, undertaken by water sprayering hole 30, therefore, nearby can both sprinkle water equably from watering pipeline 6 to the broad area in a distant place.
Therefore, can provide to have and make and to implement the watering pipeline 6 that watering uniformly becomes possibility and can guarantee the water sprayering hole 20 of the suitable intensity of watering with low watering height, in the nearby position of watering pipeline 6 reliably to broader zone.
In addition, if only with in the past water sprayering hole 3050, to guarantee watering zone to a certain degree in the zone nearby of watering pipeline, need on watering pipeline, wear the different water sprayering hole in many apertures 3050 ... as the watering pipeline 6 of this example, can with the combination of water sprayering hole 20 in wear the water sprayering hole 20 that lacks than quantity in the past.The uniformity of its inner hydraulic pressure improves when like this, making elongation watering pipeline 6.Can make its long size raising.
For another other example of the present invention, with Figure 17 (a), Figure 17 (b), and Figure 18 be that the basis makes the following instructions.In this example, the method that adopts 2 pairs of vinyl plastics films of the watering pipeline greenhouse that illustrates in the above-mentioned example to carry out the mist cooling is described.
(test method)
Adopt the mist cooling test of the watering pipeline of this example to carry out like that by following.
(watering pipeline)
Watering aperture: 0.3mm
The position of water sprayering hole: about 10 degree and about 170 degree (prescriptive procedure of the position in relevant hole please refer to example 3)
(test vinyl plastics film greenhouse)
7.2m open pipe chamber
Raise crop: cucumber
Cultivation ridge number: 4 ridges
(watering pipeline method to set up)
The height of 2m is provided with 2 on the ground
(method that watering is handled)
Every watering in 1 hour 1 minute (watering in 11 o'clock, 12 o'clock, 13 o'clock)
Pressure of supply water: 0.2MPa
Figure 17 (a) and Figure 17 (b), the summary that is illustrated in the watering pipeline 2 of water flowing state that use in this example, inboard constitutes; Figure 17 (a) is a stereogram; Figure 17 (b) is the cutaway view along D-D ' line direction of Figure 17 (a).
In experiment,, shown in Figure 17 (a) and Figure 17 (b), adopt the position of about 10 degree on pipeline and the structure that about 170 positions of spending dispose water sprayering hole 10 respectively in a straight line as the watering pipeline 2 that forms water sprayering hole 10.
Such on the watering pipeline 2 of this example, shown in Figure 17 (a), formation 2 row water sprayering holes 10, the water sprayering hole 10 of each bar are all uniformly-spaced to form substantially.In addition, shown in figure, when the line segment of water sprayering hole 10 that links the opposing party's row at the water sprayering hole 10 of the side from 2 row drew vertical line downwards, the position of intersecting in the approximate center of line segment formed water sprayering hole 10.That is, the watering pipeline 2 that uses in this example shown in Figure 17 (b), alternately forms water sprayering hole 10 at the 1st quadrant and the 2nd quadrant of cutaway view.
Figure 18 is used for illustrating the skeleton diagram of method that adopts watering pipeline of the present invention, carries out the mist cooling of vinyl plastics film greenhouse.Shown in figure, from the vaporific fine water droplets of the water that disperses of the watering of the water sprayering hole 10 of the watering pipeline 2 that is disposed at the top, can be to raise crop make object 110 spray sprinklers.Like this, the heat of vaporization by the water that disperses can make the temperature in the vinyl plastics film greenhouse 100 reduce.
By above-mentioned mist cooling test, bring the result that the influence of room temperature in the vinyl plastics film greenhouse 100 and humidity draws the spray sprinkler of relevant employing watering pipeline 2 and be shown in Figure 27.
As shown in figure 27, by carrying out 1 minute interval watering every 1 hour with watering pipeline 2, the temperature in the vinyl plastics film greenhouse 100, descend 4 ℃～5 ℃ after about 8 minutes in watering.And this cooling effect continues about 15 minutes after watering, gets back to the preceding temperature of watering after about 30 minutes.In addition, the relative moisture in the vinyl plastics film greenhouse 100 raise 10%～15% before when watering causes temperature to reduce, than watering, but the increase of the relative moisture of degree is not remarkable especially like this.
In addition, in this example, carry out the mist cooling by sprinkling water, still to 2 watering pipelines 2 of ridge configuration of 4 in the vinyl plastics film greenhouse 100, every 1 hour, the quantity of watering pipeline and watering are not limited thereto at interval, can set by cooling effect as required.
Like this, the water sprayering hole watering by watering pipeline disperse water since the effect of X perforation by miniaturization, become vaporific fine water droplets, can promote gasification, utilize this heat of vaporization can make the indoor temperature of vinyl plastics film greenhouse reduce about 5 ℃.
Here, aspect the mist cooling in vinyl plastics film greenhouse, the past, continue to use always possess the power sprayer that is used for making mist generation usefulness, the nozzle that sprays these mists, at the indoor device that makes the high price of the device that nozzle moves usefulness.But, exist these to install the problem of expensive prices.
To this, owing to adopt the watering pipeline of the water sprayering hole of the X perforation that possesses this example to carry out the mist cooling, (above-mentioned in the past installed about below 1/10) can realize the mist cooling with considerably less expense.
In addition, the watering pipeline of this example, the mist that is not limited to vinyl plastics film greenhouse cools off, and the mist that also can be used for animal house cools off, sterilizes, reaches cleaning etc.
For another other example of the present invention, with Figure 19 (a), Figure 19 (b), Figure 20 (a), and Figure 20 (b) be that the basis makes the following instructions.In this example, to adopt the watering pipeline 3 that illustrates in the above-mentioned example, to do object 110 below (making culture medium for cultivating one side of the object 110) method of laying, culture medium for cultivating 120 being carried out watering the part describe.In addition, also can adopt watering pipeline 2 to replace watering pipeline 3.In addition, for ease of explanation,, be omitted with going up same symbol, its explanation for the member of the member said function shown in the accompanying drawing that has with above-mentioned example.
Figure 19 (a) and Figure 19 (b) are to be used for illustrating utilizing watering pipeline 3 of the present invention to carry out the figure of the method for this example of watering the part; Figure 19 (a) is illustrated in the front elevation that lays the state of watering pipeline 3 on the culture medium for cultivating 120, and Figure 19 (b) is illustrated in the side view that lays the state of watering pipeline 3 on the culture medium for cultivating 120.In addition, shown in Figure 19 (a), the situation of 1 mound planting, 2 row of culture medium for cultivating 120 being made object 110 describes.
Here, each row of water sprayering hole 20, be formed at the downside of ear 23, according to definition with the position of the water sprayering hole 20 of Figure 12 explanation, can be expressed as, above at 180 degree, less than the position of the scopes of 270 degree and/or, 270 degree are above, less than the position of 360 scopes of spending, with linearity formation water sprayering hole 20.
Then, adopt Figure 20 (a) and Figure 20 (b), the method for being watered in part pipeline 200, in the past of using point from drop hole 210 to drip to water describes.Figure 20 (a), expression and culture medium for cultivating 120 pipeline 200 that will water contiguously is laid in the state of the cardinal principle central authorities of the row of making object 110.Shown in figure, drip with point water, water, a little drips owing to only drip under it 210 when discharging from the drop hole, carry out the part and water.
Therefore, dripping when watering with point, the scope of drop water saturates is confined to the culture medium for cultivating mid point horizontal scope of soaking into of dripping, and therefore, shown in Figure 20 (a), only lays in the central authorities that make object 110, can not water in enough scopes in the past.For this reason, at least, need lay the pipeline 200 that waters respectively at each row of making object 110.
In addition, especially doing the cultivation initial stage before the root expansion in the broad range of object in culture medium for cultivating, if saturated with water not in the broad range in culture medium for cultivating will be leaned on manually and water to being positioned at not waterlogged scope, this bothers very much.
Again, drip and water, because point drips and will drip repeatedly at the same area of culture medium for cultivating, can produce depression in its position of dripping, form the passage of specific water with point.Its result appears at the more uneven problem of soaking into of water in the culture medium for cultivating., rely under the drop water droplet in the past, at the very difficult uniform sprinkling of realizing of the broad range of culture medium for cultivating for this reason.
To this, sprinkling method shown in Figure 19 (a) and 19 (b), this example, be adopt have in above-mentioned example with Fig. 8～Figure 11 (c) but illustrate, in the method for the watering pipeline 2 of the water sprayering hole 20 of uniform sprinkling near it.
For this reason, shown in figure (a),, can carry out the abundance watering equably to two sides' the object 110 of doing by lay 1 watering pipeline 2 at the center of the row of making object 110.In addition, shown in figure (b), can be respectively the object 110 of doing of each row be carried out sufficient uniformly watering.Therefore, as to the cultivation initial stage before the broad range intramedullary expansion root the sprinkling method of making object 110 when using, do not water by hand yet.
Again,, nearby clash into, become vaporific fine water droplets at the utmost point of water sprayering hole 20 from the water that disperses (spray water) of water sprayering hole 20, therefore, than point drip, to the surge pressure of culture medium for cultivating 120 very a little less than.Therefore, can eliminate because of sprinkle water repeatedly, form depression in the specific region of culture medium for cultivating 120, produce water passage, produce the water that disperses uneven to soaking into of medium, by the drip problem of the sprinkling method that causes of point.
