【考案の詳細な説明】
この考案は薬液散布ノズル、主としてトラクターにセッ
トして除草剤を均一に撒布するためのノズル（−名曲面
ノズル）の改良に関するものである。[Detailed Description of the Invention] This invention relates to the improvement of a chemical spray nozzle, mainly a nozzle (known as a curved surface nozzle), which is set on a tractor and is used to uniformly spray herbicides.
この種ノズルは周側−面に横溝型の切欠部が形成してあ
り、元側中心部の噴孔から噴射した薬液は前記切欠部の
傾斜奥壁に触れながら奥壁と土壁間の移行曲面を経て土
壁に添って土壁に並行の暮秋に拡散する。This type of nozzle has a horizontal groove-shaped notch formed on the circumferential side, and the chemical solution injected from the nozzle hole in the center of the base side touches the sloped back wall of the notch and transfers between the back wall and the earthen wall. After passing through a curved surface, it spreads along the earthen wall in late autumn parallel to the earthen wall.
ところで従来のこの種ノズルは黄銅の如き素材で短軸形
を呈しその周面に横溝型の切欠部を形成し、元端側に前
記切欠部内に開口する噴孔があけてあり、薬液の噴出圧
が大であるために噴孔が摩耗して経が大となり早期に使
用に耐えなくなるという欠点がある。By the way, the conventional nozzle of this type is made of a material such as brass and has a short shaft shape, and has a horizontal groove-shaped notch formed on its circumferential surface, and has a nozzle opening in the notch on the base end side, so that the chemical solution can be ejected. Since the pressure is high, the nozzle holes are worn out and the warp becomes large, which has the disadvantage that it becomes unusable at an early stage.
この考案は上記従来の欠点を解決したものである。This invention solves the above-mentioned conventional drawbacks.
以下この考案の実施例を添付図面に基いて説明する。Embodiments of this invention will be described below with reference to the accompanying drawings.
第１図において、１は薬液散布用のノズル杆、Ａは本考
案の薬液散布ノズルであり、袋ナツト２により前記ノズ
ル杆１先端の口金３に締着されている。In FIG. 1, 1 is a nozzle rod for spraying a chemical liquid, and A is a chemical liquid spraying nozzle of the present invention, which is fastened to a cap 3 at the tip of the nozzle rod 1 with a cap nut 2.
第２図第３図はノズルのみを拡大して示しており４はノ
ズル本体、５はノズル本体に装填されるオリフィスであ
る。2 and 3 show only the nozzle in an enlarged manner, 4 is the nozzle body, and 5 is the orifice loaded in the nozzle body.
ノズル本体４は黄銅を素材とし短軸形を呈しその元端に
前記袋ナツト２がかかる鍔縁６が形成しである。The nozzle body 4 is made of brass, has a short shaft shape, and has a flange 6 formed at its base end on which the cap nut 2 is fitted.
ノズル本体４の周側−面には深さが軸心部に達する横溝
型の切欠部７が形成してあり且つこの切欠部内の奥壁ａ
は本体４の軸心線と中央部で交差し土壁す側が浅くなる
傾斜となっていて奥壁の上部はゆるやかな湾曲で土壁に
移行する曲面Ｃを構成している。A transverse groove-shaped notch 7 whose depth reaches the axial center is formed on the circumferential surface of the nozzle body 4, and a deep wall a in this notch is formed.
intersects the axial line of the main body 4 at the center and is sloped so that the earthen wall side becomes shallower, and the upper part of the back wall forms a curved surface C that transitions to the earthen wall with a gentle curve.
ノズル本体の鍔縁６が存在する側の端面にはオリフィス
装填凹部８が形成してあり且つ凹部の中央部には横溝型
切欠部７に連通する窓孔９が形成しである。An orifice loading recess 8 is formed in the end face of the nozzle body on the side where the flange 6 is present, and a window hole 9 communicating with the horizontal groove-shaped notch 7 is formed in the center of the recess.
オリフィス５は例えばステンレスの如き耐摩耗性材より
なる円板形を呈しその中心部に噴孔１０を設けたもので
ある。The orifice 5 is made of a wear-resistant material such as stainless steel and has a disk shape, and has a nozzle hole 10 in its center.
尚図示のオリフィスは円板部を周縁を除き一方に半球状
に膨出して膨出部内の凹部で圧送液を噴孔１０の方に導
き衝突させて噴孔から拡散させるようにしである。The illustrated orifice has a disk portion that bulges out in a hemispherical shape on one side except for the periphery, and a concave portion within the bulge portion guides the pumped liquid toward the nozzle hole 10 where it collides with the liquid and diffuses from the nozzle hole.
この考案は上記したような構造であり、このノズルは噴
孔１０がノズル本体とは別体の、耐摩耗性材よりなる円
板の中心部に噴孔を穿孔したオリフィスにしであるので
、噴孔が摩耗する度合が著しく少く、且つノズルの製造

すことができ更に又噴出流量は噴孔径の異るオリフィス
と取り替えることで簡単に調節することができるという
幾多の優れた効果がある。This nozzle has the structure described above, and the nozzle has an orifice formed in the center of a disc made of a wear-resistant material that is separate from the nozzle body. The degree of hole wear is significantly lower, and the nozzle is much easier to manufacture than conventional nozzles, resulting in lower cost and moreover, the jetting flow rate can be easily adjusted by replacing the orifice with a different nozzle diameter. There are many excellent effects that can be achieved.
