Description
【０００１】[0001]
本考案は、植物に灌水する際にホースの先端に取り付けて用いられる灌水器の 改良に関する。 The present invention relates to an improvement of a watering device attached to a tip of a hose when watering a plant.
【０００２】[0002]
従来のこの種の灌水器としては、ホースの先端に取り付け可能なパイプの先端 に、該先端開口面積を拡大する略半球状の裏蓋が取り付けられると共に、該裏蓋 の拡大された開口部には多数の噴射孔を有する噴射板が取り付けられた構成のも のが知られている。 In a conventional water irrigation device of this type, a substantially hemispherical back lid that expands the opening area of the tip is attached to the tip of a pipe that can be attached to the tip of a hose, and the opening of the back lid is enlarged. It is known that an injection plate having a large number of injection holes is attached.
【０００３】[0003]
しかしながら、上述のような従来の灌水器にあっては、パイプの内径で絞られ た高圧水が絞られた状態のままで噴射板に供給される構造であるため、噴射板の 中心部と外周部とで受圧する水圧に差が生じ、このため各噴射孔から噴射される 水粒や噴射水圧が不揃いとなって灌水むらが生じると共に、前記水圧差は供給水 圧を高めるにつれて大きくなることから供給水圧にも限度があり、従って灌水量 も少くなってしまうという問題があった。 However, in the conventional irrigation system as described above, the high-pressure water squeezed by the inner diameter of the pipe is supplied to the jet plate in the squeezed state, so that the central part and the outer periphery of the jet plate are Since there is a difference in the water pressure received between the parts, the water droplets injected from each injection hole and the water pressure are not uniform, resulting in uneven irrigation, and the water pressure difference increases as the supply water pressure increases. There was a problem that the supply water pressure was also limited and the irrigation volume was also small.
【０００４】 また、特に、中心部の噴射孔から噴射される水の勢いが強くなるため、幼苗を 倒したり土を吹き飛ばす等の不都合が生じるという問題がある。[0004] Furthermore, in particular, the momentum of water sprayed from the spray hole in the central portion becomes strong, so that there is a problem in that inconveniences such as overturning seedlings and blowing away soil occur.
【０００５】 そこで本考案ではかかる問題点を解消し、水粒の揃った細かく柔らかい水を大 量にかつ広範囲にむらなく噴射することが出来る灌水器を提供することを目的と するものである。In view of the above, it is an object of the present invention to solve the above problems and to provide a watering device capable of spraying a large amount of fine and soft water with uniform water particles over a wide area without unevenness.
【０００６】[0006]
上述の目的を達成するために、本考案の灌水器では、ホースの先端に取り付け 可能なパイプの先端に、該先端開口面積を拡大する略半球状の裏蓋が取り付けら れると共に、該裏蓋の拡大された開口部には多数の噴射孔を有する球面状の噴射 板がパイプの軸線方向に対して傾斜状に取り付けられた灌水器において、 前記パイプのホース取付側に所定の長さだけ他の部分よりは小口径の絞り部を 形成した。 In order to achieve the above-mentioned object, in the irrigator of the present invention, a substantially hemispherical back cover that expands the opening area of the tip is attached to the tip of the pipe that can be attached to the tip of the hose, and the back lid is attached. In the irrigator in which a spherical injection plate with a large number of injection holes is attached to the enlarged opening of the pipe in an inclined shape with respect to the axial direction of the pipe. The narrowed part has a smaller diameter than the part marked with.
【０００７】[0007]
本考案の灌水器では、上述のように構成されるので、ホースから供給された高 圧水は、まずパイプの絞り部で一旦絞られた後、絞り部よりは口径の大きい他の 部分を通過する際に減圧された状態で裏蓋内に供給されるため・噴射板に受ける 水圧が均一化される。そして、この点は供給水圧を上げても変化せず、水量のみ を増大させることが出来る。 Since the irrigation device of the present invention is configured as described above, the high pressure water supplied from the hose is first squeezed by the squeezing part of the pipe and then passes through another part having a larger diameter than the squeezing part. Since the water is supplied to the back cover in a depressurized state, the water pressure received by the spray plate is made uniform. And this point does not change even if the supply water pressure is increased, and only the water volume can be increased.
【０００８】 従って、水粒の揃った細かく柔らかい水を大量かつ広範囲にむらなく噴射する ことが出来る。Therefore, it is possible to spray a large amount of fine and soft water having uniform water particles evenly over a wide range.
【０００９】[0009]
図１及び図２は本考案実施例の灌水器Ａを示しており、この実施例では、供給 水圧が２Ｋｇ／ｃｍ２までのものについて説明する。1 and 2 show an irrigator A according to an embodiment of the present invention, and in this embodiment, a water supply pressure up to 2 Kg / cm 2 will be described.
【００１０】 この灌水器Ａは、パイプ１と裏蓋２と噴射板３とで構成されている。The watering device A is composed of a pipe 1, a back cover 2 and an injection plate 3.
【００１１】 前記パイプ１は、しんちゅうで形成されると共に、そのホース取付側に他の大 口径部１ａよりは小口径の絞り部１ｂが形成されている。即ち、大口径部１ａは その口径が１９ｍｍで長さが１００ｍｍ〜１１０ｍｍに形成される一方、小口径 部はその口径が１７．５ｍｍで長さが２８０ｍｍ〜３００ｍｍに形成されている 。The pipe 1 is made of brass, and a narrowed portion 1b having a smaller diameter than the other large diameter portion 1a is formed on the hose mounting side. That is, the large diameter portion 1a has a diameter of 19 mm and a length of 100 mm to 110 mm, while the small diameter portion has a diameter of 17.5 mm and a length of 280 mm to 300 mm.
【００１２】 前記裏蓋２は、銅で略半球状に形成されていて、その開口面が前記パイプ１の 軸方向に対し４５°の角度を持つように大口径部１ａの先端に取り付けられてい る。そしてこの裏蓋２はその開口径が７０ｍｍに形成されている。The back cover 2 is made of copper and has a substantially hemispherical shape, and is attached to the tip of the large diameter portion 1 a so that the opening surface thereof forms an angle of 45 ° with the axial direction of the pipe 1. It The back cover 2 has an opening diameter of 70 mm.
【００１３】 前記噴射板３は、しんちゅうで球面状に形成されていて、１７００個の噴射孔 ３ａが形成されている。そしてこの各噴射孔３ａは、図２の拡大図に示すように 、入口側口径が０．２ｍｍ上で、出口側が０．１５ｍｍに形成されている。The injection plate 3 is made of brass and has a spherical shape, and 1700 injection holes 3 a are formed. As shown in the enlarged view of FIG. 2, each of the injection holes 3a has an inlet side diameter of 0.2 mm and an outlet side of 0.15 mm.
【００１４】 この実施例の灌水器Ａでは上述のように構成されるので、ホースから供給され た２Ｋｇ／ｃｍ２の高圧水は、まずパイプ１の絞り部１ｂで一旦絞られた後、大 口径部１ａを通過する際に減圧されるため、この減圧された状態で裏蓋２内に供 給され、これにより噴射板３の全体に均一化された状態で水圧を受けることにな る。Since the irrigator A of this embodiment is configured as described above, the high-pressure water of 2 kg / cm 2 supplied from the hose is first squeezed by the squeezing portion 1b of the pipe 1 and then has a large diameter. Since the pressure is reduced when passing through the portion 1a, it is supplied in the back cover 2 in this reduced pressure state, and as a result, the entire jet plate 3 is subjected to water pressure in a uniformed state.
【００１５】 従って、各噴射孔３ａから水粒のそろった細かく柔らかい水が大量かつ広範囲 にむらなく噴射される。Therefore, a large amount of fine and soft water with uniform water droplets is uniformly and widely sprayed from each spray hole 3a.
【００１６】 尚、前記各部の寸法は、使用する供給水の水圧に応じて変化する。The dimensions of the above-mentioned parts change according to the water pressure of the supply water used.
【００１７】[0017]
以上説明したように、本考案の灌水器では、パイプのホース取付側に所定の長 さだけ他の部分よりは小口径の絞り部を形成したことで、噴射板に受ける水圧を 均一化させることができ、これにより、水粒の揃った細かく柔らかい水を大量か つ広範囲にむらなく噴射させることが出来るようになるという効果がある。 As described above, in the irrigation device of the present invention, the water pressure received by the jet plate is made uniform by forming a narrowed portion on the hose mounting side of the pipe by a predetermined length and having a smaller diameter than other portions. This has the effect of making it possible to spray a large amount of fine, soft water with uniform water droplets over a wide area evenly.
