提供しようとするものである。DETAILED DESCRIPTION OF THE INVENTION This invention relates to the improvement of a chemical spray nozzle, mainly a nozzle (- famous curved surface nozzle) that is set on a tractor to spray herbicide uniformly, and its purpose is to spray a spray rod. To provide a nozzle that prevents the spray curtain of each nozzle from overlapping with the adjacent spray curtain when a plurality of nozzles are installed at equal intervals, and also allows the spray pattern to be changed and adjusted.
以下この発明の実施例を添付図面に基いて説明する。Embodiments of the present invention will be described below with reference to the accompanying drawings.
第１図、第２図において、Ａはノズル本体であり、短軸
形を呈していてその元端にノズル杆の口金に袋ナツトで
締着するための鍔縁１が形成しである。In FIGS. 1 and 2, A is the nozzle body, which has a short shaft shape and has a flange 1 formed at its base end for fastening to the mouthpiece of the nozzle rod with a cap nut.
ノズル本体の周側−面には深さが軸心部に達する横溝型
の切欠部２が形成してあり、且つこの切欠部内の奥壁ａ
と上壁すは、奥壁ａが本体Ａの軸心線と中央で交差し土
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
かな彎曲で土壁に移行する曲面Ｃを構成して（・る。A transverse groove-shaped notch 2 whose depth reaches the axial center is formed on the circumferential side of the nozzle body, and a deep wall a in this notch
The upper wall has a slope where the back wall a intersects the axis of the main body A at the center and the earth wall side becomes shallower, and the upper part of the back wall forms a curved surface C that transitions to the earth wall with a gentle curvature. Do(・ru.
ノズル本体の元端端面にはオリフィス装填用凹部３が形
成してあり、且つ凹部３の中央部には切欠部２に連通す
る窓孔４が形威しである。An orifice loading recess 3 is formed in the proximal end face of the nozzle body, and a window hole 4 communicating with the notch 2 is formed in the center of the recess 3.
Ｂはノズル本体Ａの凹部３に装填された別体のオリフィ
スであり、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５が設けである。B is a separate orifice loaded in the recess 3 of the nozzle body A, and is made of a wear-resistant material such as stainless steel and has a disk shape, with a nozzle hole 5 provided in the center thereof.
このノズルは噴口５から線状に噴射するスプレー化した
液が切欠部２内で傾斜奥壁ａに触れながら曲面Ｃを経て
上壁すに添い、土壁に並行の暮秋に拡散される。In this nozzle, a sprayed liquid is ejected linearly from the nozzle 5, touches the sloped back wall a in the notch 2, passes through the curved surface C, follows the upper wall, and is diffused in late autumn parallel to the earthen wall.
特にこの発明は横溝型切欠部２が切欠部の両端方向を水
平より所要角度傾斜させたものである。In particular, in this invention, the horizontal groove type notch 2 has both ends thereof inclined at a required angle from the horizontal.
しかるときは、第５図に示すようにノズル杆６に複数個

出するスプレーのパターン７が斜め並行となり隣接のス
プレーパターンと重なり合うことがなく、従って２頭以
上のノズルの組合せとした場合に広巾均質な散布とする
ことができるという効果がある。In such a case, even if multiple nozzles are attached to the nozzle rod 6 in the same direction as shown in Fig. 5, the spray patterns 7 ejected from each nozzle will be diagonally parallel and will not overlap with adjacent spray patterns. Therefore, when two or more nozzles are combined, there is an effect that uniform spraying over a wide area can be achieved.
又このノズルはオリフィスＢを別体のものにしであるの
で、その噴口５を第１図、第２図のようにノズル本体Ａ
の軸線に一致させると第５図のスプレーパターン７のよ
うに横溝型切欠部２の傾斜上位側に対応する部分イで大

−１におけるようにオリフィスＢ−１をその噴口５ａが
横溝型切欠部２における上壁すに直角の向きにすること
により第６図のスプレーパターン７ａのように左右の広
がり度を同じにすることができ、散布面に対応しオリフ
ィスを取り替えてスプレーパターンを容易に変更できる
という効果がある。Also, since this nozzle has a separate orifice B, its nozzle 5 is connected to the nozzle body A as shown in Figures 1 and 2.
When aligned with the axis of the nozzle body A of FIGS. 3 and 4, the spray pattern 7 in FIG.
-1, by orienting the orifice B-1 so that its nozzle 5a is perpendicular to the upper wall of the horizontal groove-shaped notch 2, the degree of spread on the left and right sides can be made the same as in the spray pattern 7a in FIG. This has the effect that the spray pattern can be easily changed by replacing the orifice according to the spraying surface.
尚このノズルは噴口が耐摩耗性オリフィスに形成しであ
るので噴口の摩耗が少く、長期の使用に耐え得る。Since the nozzle of this nozzle is formed into a wear-resistant orifice, the nozzle suffers little wear and can withstand long-term use.
