本発明の実施の形態に係る薬液噴霧器について実施例１及び実施例２を参照しながら詳細に説明する。 A chemical sprayer according to an embodiment of the present invention will be described in detail with reference to Example 1 and Example 2.
本発明の実施例１に係る薬液噴霧器について図１乃至図４を参照しながら詳細に説明する。図１は本発明の実施例１に係る薬液噴霧器の全容を示す概念図である。
本発明の実施例１に係る薬液噴霧器１Ａは、大まかに説明すると、図１に示すように、上部に第１，第２の上部開口２ａ，２ｂを有する容器部２と、この第１の上部開口２ａにその導出部６ｂが挿設されながら取り付けられる回収還流部４と、容器部２内に収容される図示しない薬液をミスト状に噴霧するための噴霧部とにより構成されている。この噴霧部は、ヘッダー３とこれに接続される供給管５により構成され、ヘッダー３のノズル１９（噴霧口）に供給管５を通じて容器部２内の薬液が供給される仕組みになっている。
さらに、上述のような実施例１に係る薬液噴霧器１Ａの回収還流部４は、外縁６ａから導出口６ｃに向かって縮径する漏斗体６と、この漏斗体６の外縁６ａに延設される湾曲板状の薬液受け部７とにより構成されている。
また、実施例１に係る薬液噴霧器１Ａのヘッダー３に接続される供給管５は、容器部２の第２の上部開口２ｂに挿設され供給管５の下端部は容器部２の底に達していて、容器部２内に収容される薬液の量が少ない場合でもヘッダー３への薬液の供給が可能になっている。
A chemical sprayer according to Embodiment 1 of the present invention will be described in detail with reference to FIGS. FIG. 1 is a conceptual diagram showing the whole of the chemical sprayer according to Embodiment 1 of the present invention.
The chemical sprayer 1A according to the first embodiment of the present invention will be roughly described. As shown in FIG. 1, the chemical sprayer 1A has a container part 2 having first and second upper openings 2a and 2b in the upper part, and the first upper part. The recirculation part 4 is attached while the lead-out part 6b is inserted into the opening 2a, and the spray part for spraying a chemical solution (not shown) contained in the container part 2 in a mist form. The spray unit is composed of a header 3 and a supply pipe 5 connected to the header 3, and is configured such that the chemical solution in the container unit 2 is supplied to the nozzle 19 (spray port) of the header 3 through the supply pipe 5.
Further, the recovery reflux part 4 of the chemical sprayer 1A according to the first embodiment as described above is extended to the funnel body 6 that is reduced in diameter from the outer edge 6a toward the outlet 6c, and the outer edge 6a of the funnel body 6. It is comprised by the curved plate-shaped chemical | medical solution receiving part 7. FIG.
Further, the supply pipe 5 connected to the header 3 of the chemical sprayer 1A according to the first embodiment is inserted into the second upper opening 2b of the container part 2, and the lower end of the supply pipe 5 reaches the bottom of the container part 2. In addition, even when the amount of the chemical liquid stored in the container portion 2 is small, the chemical liquid can be supplied to the header 3.
次に、図２を参照しながら上述のような実施例１に係る薬液噴霧器１Ａの使用方法について説明する。図２は本発明の実施例１に係る薬液噴霧器の使用状態を示す断面図である。なお、図１に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
実施例１に係る薬液噴霧器１Ａを用いて被散布対象であるぶどうの幼房１０に薬液として、例えば、ジベレリン溶液を散布するには、図２に示すように、まず、容器部２内に薬液８（ジベレリン溶液）を入れてから、容器部２の第１の上部開口２ａに、回収還流部４の漏斗体６の導出部６ｂを挿設して取付け、さらに、容器部２の第２の上部開口２ｂから容器部２の内部に、ヘッダー３に接続される供給管５の下端側を挿入してヘッダー３への薬液８の供給を可能な状態にする。
Next, a method of using the chemical sprayer 1A according to Example 1 as described above will be described with reference to FIG. FIG. 2 is a sectional view showing a usage state of the chemical sprayer according to the first embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
In order to spray, for example, a gibberellin solution as a chemical solution to the bunches 10 of grapes to be sprayed using the chemical sprayer 1A according to the first embodiment, first, as shown in FIG. 8 (gibberellin solution) is inserted, and the lead-out part 6b of the funnel body 6 of the recovery reflux part 4 is inserted and attached to the first upper opening 2a of the container part 2, and the second part of the container part 2 is further attached. The lower end side of the supply pipe 5 connected to the header 3 is inserted into the container portion 2 from the upper opening 2b so that the chemical solution 8 can be supplied to the header 3.
この後、ぶどうの木の枝から延びるぶどうの幼房１０を、回収還流部４の薬液受け部７とヘッダー３のノズル１９の間である漏斗体６上に来るように配置してから、ヘッダー３を操作してノズル１９から噴射されるミスト状の薬液８を幼房１０に吹きつければよい。
この時、図２に示すように、ぶどうの幼房１０に当たらなかった薬液８は、幼房１０を挟んで，ヘッダー３のノズル１９と対峙して設けられる薬液受け部７の表面において受け止められ、その表面上を流れて漏斗体６内に移動し、漏斗体６の導出部６ｂを通って導出口６ｃから容器部２内に還流される。
また、ぶどうの幼房１０に吹きつけられた薬液８のうち、幼房１０の表面に付着しきれなかった薬液８は、幼房１０から滴り落ちて漏斗体６に流化し、漏斗体６の導出部６ｂを経て容器部２内に還流される。
After that, the vine cuboid 10 extending from the branch of the vine is arranged so as to come on the funnel body 6 between the chemical solution receiving part 7 of the recovery reflux part 4 and the nozzle 19 of the header 3, and then the header. 3 is operated and the mist-like chemical solution 8 sprayed from the nozzle 19 is sprayed onto the juvenile 10.
At this time, as shown in FIG. 2, the drug solution 8 that has not hit the grape cubicle 10 is received on the surface of the drug solution receiving portion 7 provided facing the nozzle 19 of the header 3 across the cubule 10. Then, it flows on the surface, moves into the funnel body 6, passes through the outlet portion 6 b of the funnel body 6, and returns to the container portion 2 from the outlet port 6 c.
In addition, of the chemical solution 8 sprayed on the grape cubicle 10, the chemical solution 8 that did not adhere to the surface of the cubule 10 drips from the cubule 10 and flows into the funnel body 6. It is refluxed into the container part 2 through the lead-out part 6b.
このように、本発明の実施例１に係る薬液噴霧器１Ａによれば、必要量の薬液８を常時携行しながら被散布対象である，例えば，幼房１０に薬液８を噴霧することができるとともに、余剰な薬液８を確実に回収して再利用することができる。このような実施例１に係る薬液噴霧器１Ａでは、従来例のように、薬液８を一時収容するための容器部２と、薬液８を噴霧するための噴霧部とそれを備えたカップ部が長い管でつながれた形態になっておらず、容器部２に噴霧部３，５及び回収還流部４が短く接続した形態になっているので、装置自体が極めてコンパクトで軽量であり、携行が容易である。
加えて、実施例１に係る薬液噴霧器１Ａでは、先に述べた従来例とは異なり、薬液８を噴霧するための噴霧部３，５と、噴霧されて余剰となった薬液８を受け止めて回収するための回収還流部４が一体ではなく、完全に分離された独立の構成として設けられているので、構造上も噴霧部３，５と回収還流部４とを一体に連結する必要がなく、これにより、実施例１に係る薬液噴霧器１Ａの操作性・作業性の自由度が極めて高くなると同時に、製造が容易になっている。この結果、作業効率に優れる薬液噴霧器を廉価に提供することができる。
また、実施例１に係る薬液噴霧器１Ａにおいて、回収還流部４の薬液受け部７と、ヘッダー３とは互いに独立して、これらが対向した配置になっているので、特に薬液受け部７を鉛直下方に配置した場合には、薬液受け部７がほぼ水平になっても被散布対象への薬液８の噴霧と余剰な薬液８の回収を行うことができる。
そして、実施例１に係る薬液噴霧器１Ａは小型で軽量であり、しかも、従来例のように長い管体を備えるものではないので、作業者による薬液噴霧器１Ａの姿勢を傾ける等の配置の変更が極めて容易である。このため、薬液８の散布時に、幼房１０を支える茎を故意に曲げる必要が少なくなるので、薬液８の散布時にぶどうの幼房１０を折り取ってしまうリスクを軽減することができる。
As described above, according to the chemical sprayer 1A according to the first embodiment of the present invention, the chemical solution 8 can be sprayed on, for example, the juvenile 10 which is a target to be sprayed while always carrying the required amount of the chemical solution 8. The excess chemical solution 8 can be reliably recovered and reused. In the chemical solution sprayer 1A according to the first embodiment, as in the conventional example, the container portion 2 for temporarily storing the chemical solution 8, the spray portion for spraying the chemical solution 8, and the cup portion including the same are long. It is not in a form connected by a pipe, and since the spray parts 3 and 5 and the recovery reflux part 4 are shortly connected to the container part 2, the apparatus itself is extremely compact and lightweight, and easy to carry. is there.
In addition, in the chemical sprayer 1A according to the first embodiment, unlike the conventional example described above, the spray units 3 and 5 for spraying the chemical liquid 8 and the chemical liquid 8 that has been sprayed and received are collected and collected. Since the recovery reflux unit 4 is not integrated and is provided as a completely separated independent configuration, there is no need to connect the spray units 3 and 5 and the recovery reflux unit 4 together in terms of structure, Thereby, the freedom degree of operativity and workability | operativity of 1 A of chemical | medical solution sprayers based on Example 1 becomes very high, and manufacture is easy. As a result, a chemical sprayer excellent in work efficiency can be provided at low cost.
Further, in the chemical sprayer 1A according to the first embodiment, the chemical liquid receiving unit 7 of the recovery reflux unit 4 and the header 3 are arranged independently of each other. When arranged below, the chemical solution receiving portion 7 can be sprayed with the chemical solution 8 on the object to be sprayed and the excessive chemical solution 8 can be collected even when the chemical solution receiving portion 7 becomes substantially horizontal.
The chemical sprayer 1A according to the first embodiment is small and light, and does not include a long tube body as in the conventional example. Therefore, the operator can change the arrangement such as tilting the posture of the chemical sprayer 1A. Very easy. For this reason, since it is less necessary to intentionally bend the stem supporting the cubule 10 when the medicinal solution 8 is sprayed, it is possible to reduce the risk of breaking the grape bunches 10 when the medicinal solution 8 is sprayed.
再び、図１の説明に戻るが、実施例１に係る薬液噴霧器１Ａにおいては、容器部２の第１の上部開口２ａ近傍に、第１の上部開口２ａに向かって縮径する縮径部２ｃを設け、この縮径部２ｃの長さＡ（図１を参照）を、回収還流部４の漏斗体６の導出部６ｂの長さＢ（図１を参照）よりも短くしておくことで、漏斗体６の導出部６ｂが、容器部２の第１の上部開口２ａに単に挿設されただけの状態であっても、回収還流部４を第１の上部開口２ａから脱落し難くすることができる。
他方、上述のような縮径部２ｃや、この縮径部２ｃよりも長い導出部６ｂを備えない場合でも、容器部２に着脱可能に回収還流部４を固定することで、第１の上部開口２ａからの回収還流部４の脱落を好適に防止することができる。
より具体的には、例えば、容器部２の外側面，及び，漏斗体６の側面にそれぞれ対をなすような突起状又はフック状の掛止部１２を少なくとも２セット以上設け、容器部２の外側面に設けられる１２と，漏斗体６の側面に設けられる掛止部１２とを弾性体１３である、例えば、ゴムバンドやつるまきバネ等でつなぐことにより、容器部２の第１の上部開口２ａから回収還流部４が外れるのを好適に防止することができる。
また、容器部２の第１の上部開口２ａから回収還流部４の外れを防止する他の方法としては、例えば、回収還流部４を構成する漏斗体６の導出部６ｂの外側面を、容器部２の第１の上部開口２ａの内側面に螺設してもよいし、回収還流部４と，容器部２の第１の上部開口２ａの間に弾性体からなるパッキンを介設して回収還流部４の外れを防止してもよい。
Returning to the description of FIG. 1 again, in the chemical sprayer 1A according to the first embodiment, the diameter-reduced portion 2c that is reduced in diameter toward the first upper opening 2a in the vicinity of the first upper opening 2a of the container portion 2. And the length A of the reduced diameter portion 2c (see FIG. 1) is made shorter than the length B (see FIG. 1) of the outlet portion 6b of the funnel body 6 of the recovery reflux portion 4. Even if the lead-out part 6b of the funnel body 6 is simply inserted into the first upper opening 2a of the container part 2, the recovery reflux part 4 is made difficult to fall out of the first upper opening 2a. be able to.
On the other hand, even when the reduced diameter part 2c as described above and the lead-out part 6b longer than the reduced diameter part 2c are not provided, the recovery reflux part 4 is fixed to the container part 2 so as to be removable. It is possible to suitably prevent the recovery reflux portion 4 from dropping from the opening 2a.
More specifically, for example, at least two sets of protrusion-like or hook-like latching portions 12 that form a pair on the outer side surface of the container portion 2 and the side surface of the funnel body 6 are provided. The first upper portion of the container portion 2 is formed by connecting the outer surface 12 and the hooking portion 12 provided on the side surface of the funnel body 6 with an elastic body 13 such as a rubber band or a helical spring. It can prevent suitably that the collection | recovery reflux part 4 remove | deviates from the opening 2a.
Further, as another method for preventing the recovery reflux part 4 from coming off from the first upper opening 2a of the container part 2, for example, the outer surface of the lead-out part 6b of the funnel body 6 constituting the recovery reflux part 4 may be The inner surface of the first upper opening 2a of the part 2 may be screwed, or a packing made of an elastic material may be interposed between the recovery reflux part 4 and the first upper opening 2a of the container part 2. The recovery reflux unit 4 may be prevented from coming off.
なお、容器部２の第１の上部開口２ａに回収還流部４を螺設したり、パッキンを介して容器部２の第１の上部開口２ａに回収還流部４を取り付ける場合には、漏斗体６の導出部６ｂから容器部２内への薬液の還流が妨げられないよう、第１の上部開口２ａと，回収還流部４との接続部分に通気口を設けておくとよい。また、漏斗体６の導出部６ｂが十分な直径を有する場合や、容器部２の第２の上部開口２ｂと供給管５の間に隙間が形成される場合には、通気口は必ずしも必要はない。
このように、容器部２に回収還流部４を着脱可能に固定することによる効果は、上述のような薬液８の散布作業時における薬液噴霧器１Ａの安定性の向上だけでなく、薬液噴霧器１Ａが分解可能となることで、そのメンテナンスを容易にすることもできる。すなわち、使用後に薬液噴霧器１Ａを分解して隅々まで洗浄することができる。
さらに、例えば、複数種類のぶどうを生産する場合には、薬液８の被散布対象である幼房１０の大きさが品種によってさまざまになるので、このような場合には、それぞれのぶどうの品種の幼房１０の大きさに応じた回収還流部４をそれぞれ準備しておき、目的に応じて適切な大きさの回収還流部４に交換して用いることができる。従って、実施例１に係る薬液噴霧器１Ａの汎用性を高めることができる。
他方、容器部２と回収還流部４とを一体に構成してもよい。この場合、容器部２から回収還流部４が外れるのを確実に防止することができる。さらに、この場合、回収還流部４における薬液受け部７を着脱可能にすることで、被散布対象の大きさに応じた薬液受け部７に交換することが可能になるので、薬液噴霧器１Ａの汎用性を高めることができる。
In addition, when the collection | recovery reflux part 4 is screwed in the 1st upper opening 2a of the container part 2, or when the collection | recovery reflux part 4 is attached to the 1st upper opening 2a of the container part 2 via packing, it is a funnel body. It is advisable to provide a vent in the connecting portion between the first upper opening 2a and the recovery reflux part 4 so that the reflux of the chemical solution from the lead-out part 6b to the container part 2 is not hindered. Further, when the lead-out portion 6b of the funnel body 6 has a sufficient diameter, or when a gap is formed between the second upper opening 2b of the container portion 2 and the supply pipe 5, the vent is not necessarily required. Absent.
As described above, the effect of detachably fixing the recovery reflux unit 4 to the container unit 2 is not only the improvement of the stability of the chemical sprayer 1A during the spraying operation of the chemical solution 8 as described above, but also the chemical sprayer 1A. Since it can be disassembled, the maintenance can be facilitated. That is, after use, the chemical sprayer 1A can be disassembled and cleaned to every corner.
Furthermore, for example, when producing a plurality of types of grapes, the size of the juvenile 10 to which the chemical solution 8 is to be applied varies depending on the variety. The recovery reflux section 4 corresponding to the size of the juvenile 10 is prepared, and the recovery reflux section 4 having an appropriate size can be exchanged and used depending on the purpose. Therefore, the versatility of the chemical sprayer 1A according to the first embodiment can be enhanced.
On the other hand, you may comprise the container part 2 and the collection | recovery reflux part 4 integrally. In this case, it is possible to reliably prevent the recovery reflux part 4 from coming off the container part 2. Furthermore, in this case, by making the chemical liquid receiving part 7 in the recovery reflux part 4 removable, it is possible to replace the chemical liquid receiving part 7 according to the size of the object to be sprayed. Can increase the sex.
また、実施例１に係る薬液噴霧器１Ａのヘッダー３は、例えば、図１に示すような把持部３ｂと操作部３ａを備えて手動で駆動するタイプのヘッダー３であってもよいし、特に図示しないが、指で押圧部を押し下げて液体を噴射させるタイプでやはり手動で駆動するタイプの噴霧部であってもよい。また、ヘッダー３の駆動方法は、必ずしも手動である必要はなく、電池等により供給される電力で駆動する自動噴霧タイプのものでもよい。
前者の場合には、すなわち、ヘッダー３を手動で駆動させる場合には、実施例１に係る薬液噴霧器１Ａをより廉価に提供できるというメリットが。他方、後者の場合には、すなわち、ヘッダー３を電力で駆動させる場合には、前者の場合に比べて製造コストはやや高くなるものの、長時間にわたって薬液８の散布作業を行う必要がある場合に、作業者の手にかかる負担を軽減することができるので、作業性を向上できるというメリットがある。
Further, the header 3 of the chemical sprayer 1A according to the first embodiment may be, for example, a header 3 of a type that is manually driven with a grip portion 3b and an operation portion 3a as shown in FIG. However, it may be a spray unit of a type that is manually driven by a type in which liquid is ejected by pressing the pressing unit with a finger. The driving method of the header 3 is not necessarily manual, and may be an automatic spray type driven by electric power supplied from a battery or the like.
In the former case, that is, when the header 3 is driven manually, there is a merit that the chemical sprayer 1A according to the first embodiment can be provided at a lower cost. On the other hand, in the latter case, that is, when the header 3 is driven by electric power, the manufacturing cost is slightly higher than in the former case, but it is necessary to perform the spraying operation of the chemical solution 8 for a long time. Since the burden on the operator's hand can be reduced, there is an advantage that workability can be improved.
さらに、実施例１に係る薬液噴霧器１Ａにおいては、容器部２から導出されて裸出する供給管５の裸出部５ａを、可撓性を有する材質により構成してもよい。
この場合、供給管５の裸出部５ａの可撓性を利用して、図２に破線で示すように、ヘッダー３の位置を自在に変化させることができるので、被噴霧対象であるぶどうの幼房１０の周囲の様々な方向から薬液８を噴霧することができる。
このように、余剰な薬液８を受け止める回収還流部４と、薬液を噴霧するヘッダー３とを完全に独立した構成として設け、かつ、ヘッダー３に接続される供給管５の少なくとも容器部２から裸出する部分を可撓性を有する材質により構成することで、作業者は***を変えることなくヘッダー３の位置だけを変更することによって、薬液受け部７との相対的な距離や位置関係を変えつつ、被散布対象の周囲の様々な方向から薬液８を散布することが可能になる。
この場合、回収還流部４にヘッダー３を一体に備えた場合に比べて、作業者はより少ない動作で被散布対象であるぶどうの幼房１０の全周に薬液８を散布することができると同時に散布残しの箇所に対して集中的に再度散布することも可能なので、薬液８の散布作業の作業効率を向上させることができる。
なお、実施例１に係る薬液噴霧器１Ａでは、容器部２の内部に供給管５の一部を挿設する場合を例に挙げて説明しているが、図示されるもの以外にも、容器部２の底の近くの側面に第２の上部開口２ｂを設け、この第２の上部開口２ｂに液漏れしないように可撓性を有する供給管５を接続してもよい。
また、容器部２の第２の上部開口２ｂに、キャップ等を介して供給管５を着脱可能に固定してもよい。この場合、薬液８の散布作業時に、不意に供給管５が容器部２から外れてしまうのを防止することができる。
Furthermore, in the chemical spray device 1A according to the first embodiment, the bare portion 5a of the supply pipe 5 that is led out from the container portion 2 and bare may be formed of a flexible material.
In this case, the flexibility of the bare portion 5a of the supply pipe 5 can be used to freely change the position of the header 3 as shown by a broken line in FIG. The medicinal solution 8 can be sprayed from various directions around the juvenile 10.
In this way, the recovery reflux section 4 for receiving the excess chemical solution 8 and the header 3 for spraying the chemical solution are provided as completely independent structures, and are barely provided from at least the container section 2 of the supply pipe 5 connected to the header 3. By configuring the protruding portion with a flexible material, the operator can change the relative distance and positional relationship with the chemical solution receiving portion 7 by changing only the position of the header 3 without changing the body position. On the other hand, it is possible to spray the chemical solution 8 from various directions around the object to be sprayed.
In this case, compared with the case where the header 3 is integrally provided in the recovery reflux unit 4, the operator can spray the chemical solution 8 over the entire circumference of the bunches 10 of the grapes to be sprayed with fewer operations. At the same time, since it is possible to spray again intensively on the remaining portions, the work efficiency of the spraying operation of the chemical solution 8 can be improved.
In the chemical sprayer 1A according to the first embodiment, the case where a part of the supply pipe 5 is inserted inside the container portion 2 is described as an example. A second upper opening 2b may be provided on a side surface near the bottom of the second upper opening 2b, and a flexible supply pipe 5 may be connected to the second upper opening 2b so as not to leak.
Further, the supply pipe 5 may be detachably fixed to the second upper opening 2b of the container part 2 via a cap or the like. In this case, it is possible to prevent the supply pipe 5 from being unexpectedly detached from the container portion 2 during the spraying operation of the chemical solution 8.
また、実施例１に係る薬液噴霧器１Ａにおいては、図１，２に示すように、供給管５の下端にメッシュ状又は多孔体からなるストレナー９を設けてもよい。この場合、還流された余剰な薬液８中にぶどうの花粉、おしべ、花茎等の幼房１０の一部が混入した場合に、これらが供給管５から薬液８とともに吸い上げられて目詰まりするのを防止できる。
なお、図１，２ではストレナー９を供給管５の下端に設ける場合を例に挙げて説明しているが、ストレナー９は漏斗体６における椀状部分と導出部６ｂの境界に位置する孔に設けてもよいし、漏斗体６の導出口６ｃに設けてもよいし、これらのいずれか一方と、供給管５の下端部に設けてもよい。
Moreover, in the chemical spray device 1A according to the first embodiment, as shown in FIGS. 1 and 2, a strainer 9 made of a mesh or a porous body may be provided at the lower end of the supply pipe 5. In this case, when a part of the young cell 10 such as pollen of vine, stamen, flower stem, etc. is mixed in the refluxed excess chemical solution 8, these are sucked together with the chemical solution 8 from the supply pipe 5 and become clogged. Can be prevented.
1 and 2, the case where the strainer 9 is provided at the lower end of the supply pipe 5 is described as an example. However, the strainer 9 is formed in a hole located at the boundary between the hook-like portion of the funnel body 6 and the outlet portion 6b. It may be provided, may be provided at the outlet 6 c of the funnel body 6, or may be provided at any one of these and the lower end portion of the supply pipe 5.
ここで、図１，２及び図３を参照しながら実施例１に係る薬液噴霧器１Ａの収納方法について説明する。図３は、本発明の実施例１に係る薬液噴霧器の収納状態を示す斜視図である。なお、図１又は図２に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
実施例１に係る薬液噴霧器１Ａでは、図１，２に示すように、ヘッダー３に係止用のループ１５を、回収還流部４の漏斗体６の側面に先のループ１５を係止するためのフック１４を備えて、漏斗体６の側面にヘッダー３を係止可能としてもよい。
