この考案は、農作物などに水を散布供給する際
に好適に使用される灌水チユーブの改良に関する
ものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the improvement of an irrigation tube that is suitably used when spraying and supplying water to agricultural crops.
従来より、農作物などに水を散布供給するに際
しては、第６図に示すように、灌水孔１を長手方
向に沿つて所定間隔で穿設した上半の長尺熱可塑
性フイルム３と下半の長尺熱可塑性フイルム５と

構成した灌水チユーブが提案され、需要者の便宜
に供されている。
Conventionally, when spraying and supplying water to agricultural crops, etc., as shown in FIG. An irrigation tube constructed by overlapping a long thermoplastic film 5 and welding both side edges thereof has been proposed for the convenience of users.
ところで、この種の灌水チユーブは農作物を植
生した畝間などに蛇行配置して給水管から供給さ
れる水を多数の灌水孔を介して散布するのである
が、畝間に配置する際の捩れなどにより通水する
とうねつてしまうことが多く、その結果、灌水が
水平から下方方向に散布される部分が生じて灌水
効率が低下する欠点があつた。そこでこのような
不都合を回避するために、例えば、チユーブのう
ねりを直しながら灌水孔を斜め上方に向け止具で
固定保持したり、あるいは灌水チユーブの断面を
横向き瓢箪形などに形成して安定化を図るなど
種々の工夫がなされているが、前者の場合は灌水
チユーブの設置ないしは固定作業が面倒になり、
また後者の場合は製造コストが嵩むなどさらに解
決すべき点があつた。 By the way, this type of irrigation tube is arranged in a meandering manner between the furrows where agricultural crops are planted, and the water supplied from the water supply pipe is sprayed through a large number of irrigation holes. When watered, it often undulates, and as a result, there are areas where irrigation water is sprayed downward from the horizontal, resulting in a reduction in irrigation efficiency. Therefore, in order to avoid such inconveniences, for example, while correcting the undulation of the tube, the irrigation hole is fixed and held diagonally upward with a stopper, or the cross section of the irrigation tube is formed into a horizontal gourd shape, etc., to stabilize it. However, in the former case, installing or fixing the irrigation tube becomes troublesome;
In the latter case, there were further issues to be resolved, such as increased manufacturing costs.
そこで、この考案では灌水孔を穿設した上半の
長尺熱可塑性フイルムと、この長尺熱可塑性フイ
ルムよりも肉薄に形成した下半の長尺熱可塑性フ
イルムとを重畳して両側縁を溶着することにより

易化と灌水効率の向上化を図ろうとするものであ
る。
Therefore, in this invention, the upper long thermoplastic film with irrigation holes is overlapped with the lower long thermoplastic film, which is thinner than this long thermoplastic film, and the edges on both sides are welded. By doing so, a tube body is formed, and the welded portions on both sides are configured as ribs for preventing rotation, thereby facilitating installation work and improving irrigation efficiency.
この場合、上半フイルムと下半フイルムとの間
に濾過シートを介挿配置し、この濾過シート側縁
を含む両フイルムの各側縁を所定幅で溶着すれ

上半フイルムと濾過シートとの溶着幅を下半フイ
ルムと濾過シートとの溶着幅よりも小さく設定す
れば、灌水チユーブへの通水時に上半フイルムと
濾過シートとを常に離間させることができるので
好適な濾過灌水を達成することができる。 In this case, if a filter sheet is inserted between the upper half film and the lower half film, and each side edge of both films, including the side edge of the filter sheet, is welded to a predetermined width, water can be supplied to the irrigation tube. It can be easily filtered even if it is mixed with dirt, and
By setting the welding width between the upper half film and the filter sheet to be smaller than the welding width between the lower half film and the filtration sheet, the upper half film and the filtration sheet can always be kept apart when water is passed through the irrigation tube. A suitable filtered irrigation can be achieved.
さらに、上半フイルムと下半フイルムとの間に
複数の濾過シートを介挿配置し、これらの濾過シ
ートのメツシユを下半フイルム側から上半フイル
ム側に向かつて次第に粗から密に設定すれば濾過
効率と耐久性の向上を図ることが可能となる。 Furthermore, if a plurality of filter sheets are interposed between the upper half film and the lower half film, and the mesh of these filter sheets is gradually set from coarse to dense from the lower half film side to the upper half film side. It becomes possible to improve filtration efficiency and durability.
この考案に係る灌水チユーブは、通水により水

せるものである。
In the irrigation tube according to this invention, even when the water pressure increases due to water flow and the tube becomes circular, due to the difference in thickness between the upper half film and the lower half film, the upper half film is pulled toward the lower half film, and the welded portions on both sides are separated. It is oriented diagonally downward and functions as a support on both sides, becoming a rotation-preventing rib and stabilizing the tube body.
次に、本考案に係る灌水チユーブの好適な実施
例につき添付図面を参照しながら以下詳細に説明
する。
Next, preferred embodiments of the irrigation tube according to the present invention will be described in detail with reference to the accompanying drawings.

の両フイルム１４，１６を重畳し、その両側縁を
溶着してチユーブ状に形成するとともに前記両側
溶着部を転回阻止用リブ１８，１８として構成す
るものである。 In FIG. 1, an irrigation tube 1 according to the present invention is shown.
0 is made of a thermoplastic film such as polyethylene resin and has irrigation holes 12 perforated at predetermined intervals along the longitudinal direction, for example, an upper half long film 14 with a thickness of 200 microns and a width of 50 mm, and this length. Same material as Shaku Film 14, 120 microns thick.
These two films 14 and 16 are overlapped and their both side edges are welded to form a tube shape, and the welded portions on both sides are used as rotation prevention ribs 18 and 18. It consists of
なお、この場合、転回阻止用リブ１８，１８、
すなわち、両側溶着部の長さはチユーブ状本体２
０の直径の1/3程度あるいはそれ以上に設定する
のが好ましい。 In this case, the rotation prevention ribs 18, 18,
In other words, the length of the welded parts on both sides is the length of the tube-shaped main body 2.
It is preferable to set it to about 1/3 of the diameter of 0 or more.
また、上半フイルム１４の灌水孔１２は、ダイ
ス装置でなくレーザー発振装置などにより穿孔す
れば、灌水孔１２の周縁部にバリなどが生じない
だけでなく縁部が肉厚となるので耐久性が向上
し、極めて小径の孔も穿設できるので灌水チユー
ブに噴霧あるいは点滴などの機能を付与すること
もでき好適である。 Furthermore, if the irrigation holes 12 of the upper half film 14 are drilled using a laser oscillation device or the like instead of a die device, not only will burrs not form on the periphery of the irrigation holes 12, but the edges will be thicker, resulting in increased durability. It is preferable that the irrigation tube can be provided with functions such as spraying or dripping, since it improves the water resistance and allows holes of extremely small diameter to be drilled.
このように構成される本考案に係る灌水チユー

することができる。 When water is passed through the irrigation tube according to the present invention constructed in this way, the lower half film 1 is heated by the water pressure.
Even if the film 6 has a substantially semicircular shape, the upper half film 14, which is set to be thicker than the lower half film 16, does not have the same semicircular shape, and the ribs 18, 18 (both side welded parts) are not the same as the lower half film 16. Even if the tube body 20 is twisted or turned, these ribs 18, 18 will support both sides of the tube body 20. Therefore, even if the irrigation hole 12 is arranged in a meandering manner in a furrow or the like, the irrigation hole 12 always faces diagonally upward, and the irrigation water can be reliably distributed. In addition, since the upper half film 14 is made thick, it is extremely resistant to tearing and damage due to water pressure applied to the periphery of the irrigation hole 12.
Furthermore, since it can sufficiently cope with deterioration caused by ultraviolet rays from the sun, it can be used stably for a long period of time.

を使用するのが好ましいことは言うまでもない。 2 and 3, a nonwoven filter sheet 22 of the same length and width is inserted between both films 14 and 16 of the irrigation tube shown in FIG. 1, and side edges 22a and 22b of this filter sheet 22 are Side edges 14a, 16a and 14 of both films 14, 16 including
This is another embodiment of the irrigation tube according to the present invention constructed by welding the upper half film 14 and the filter sheet 22 to the lower half film 16. By setting the width to be narrower than the welding width with the filter sheet 22, the upper half film 14 and the filter sheet 22 are
By ensuring that a gap A is provided between the filter and the filter, it is possible to prevent impossibility of watering and a decrease in filtration efficiency due to dirt and the like. In this case, it is preferable to use a nonwoven filter sheet 22 made of the same thermoplastic resin fiber as the film material so that the films 14 and 16 can be reliably kept liquid-tight when welded together. Needless to say.

る。 Furthermore, FIGS. 4 and 5 show that another filter sheet 24 is inserted between the lower half film 16 and the filter sheet 22 in the irrigation tube shown in FIG. This is yet another embodiment of the irrigation tube according to the present invention, in which the mesh of the filter sheets 22 is set coarser than that of the filter sheets 22. Since dust can be sequentially separated and filtered, it is possible to improve not only filtration efficiency but also durability.
先に述べたように、本考案に係る灌水チユーブ

て大きい。 In addition, since a gap can be maintained between the upper half film and the filter sheet when water is passed through, it is possible to prevent impediment of watering due to debris and a decrease in filtration efficiency.Furthermore, when using multiple filter sheets, it is possible to separate the garbage. It has various advantages such as being able to improve filtration efficiency and durability, and its practical effects are extremely large.
以上、本考案に係る灌水チユーブの好適な実施
