Description

本発明は、ポンプ及びモータを備えた動力型であって、薬液などの液体の噴霧に利用される噴霧機に関するものである。   The present invention relates to a sprayer that is a power type equipped with a pump and a motor and is used for spraying a liquid such as a chemical solution.

従来、このような分野の技術として、実公平07−8044号公報がある。この公報に記載された噴霧機は、背負い型であると共に、薬剤タンクの背面には凹所が設けられ、この凹所内にはバッテリ、モータ及びポンプなど様々な部品が組み込まれている。そして、この凹所の開口部分は背当てによって覆われている。さらに、薬剤タンクの横側方及び下方には、凹所に連通する2つの通気路が形成され、各通気路は、凹所内に設けられた冷却ファンの駆動によって、外気が凹所から出たり入ったりする際に利用され、凹所内に外気を導入し続けることで、モータの適切な冷却が達成される。   Conventionally, Japanese Utility Model Publication No. 07-8044 is known as a technology in such a field. The sprayer described in this publication is of a backpack type, and a recess is provided in the back of the medicine tank, and various parts such as a battery, a motor and a pump are incorporated in the recess. And the opening part of this recess is covered with the backrest. Further, two vent passages communicating with the recesses are formed on the lateral side and the lower side of the drug tank, and each of the vent passages is driven by a cooling fan provided in the recesses so that outside air can be discharged from the recesses. The motor is properly cooled by being used when entering and continuing to introduce outside air into the recess.

実公平07−8044号公報No. 07-8044

しかしながら、前述した従来の噴霧機には、薬剤タンクの横側方及び下方で開放された2つの通気路が形成されているが、各通気路は、吸気や排気のために単に溝状をなしており、ポンプやバッテリなどの部品を収容するための空間として利用することができない。従って、薬液タンクの背面側で窪みのように形成された凹所では、底面と四側面とで囲まれた空間として形成されるので、バッテリ、モータ、ポンプ、配管及び電気配線などの部品を凹所内に組み付ける際に手や工具が凹所内に入りにくく、これら部品の組付け作業やメンテナンスが難しいといった問題点がある。   However, the above-described conventional sprayer is formed with two air passages that are opened laterally and below the drug tank. However, each air passage has a groove shape for intake and exhaust. It cannot be used as a space for housing parts such as a pump and a battery. Therefore, the recess formed like a depression on the back side of the chemical tank is formed as a space surrounded by the bottom surface and the four side surfaces, so that parts such as the battery, motor, pump, piping, and electrical wiring are recessed. There is a problem in that hands and tools are difficult to enter into the recess when assembling in the place, and it is difficult to assemble and maintain these parts.

In addition, since the sprayer (1) is also required to be maintainable, it is possible to easily replace parts in the pipe housing recess (8). Furthermore, in order to improve the above-described assembly workability and maintainability, the cover (20) for covering the pipe housing recess (8) is detachable from the liquid tank (2).

また、配管収容凹部(8)内には、液体タンク(2)に固定されたポンプ(10)と、液体タンク(2)内の液体をポンプ(10)を介して外部に排出する配管系部品(18)とが取付けられ、カバー(20)には、モータ(9)に電力を供給するバッテリ(22)と、バッテリ(22)に電気的に接続された切換スイッチ(26)と、バッテリ(22)からの電力をモータ(9)に供給する電気配線系部品(28)とが取付けられていると好適である。このような構成では、液体流動系統の部品をなすポンプ(10)及び配管系部品(18)が液体タンク(2)側に設けられ、電気系統の部品をなす切換スイッチ(26)、バッテリ(22)及び電気配線系部品(28)がカバー(20)側に設けられているので、液体流動系統の部品と電気系統の部品とを個別に組み立てることができ、組立作業性が極めて良好になり、噴霧機(1)のユニット化が容易に達成される。   Also, in the pipe housing recess (8), the pump (10) fixed to the liquid tank (2) and the piping system parts for discharging the liquid in the liquid tank (2) to the outside via the pump (10) (18) and a battery (22) for supplying power to the motor (9), a changeover switch (26) electrically connected to the battery (22), and a battery ( It is preferable that an electrical wiring system component (28) for supplying electric power from 22) to the motor (9) is attached. In such a configuration, the pump (10) and the piping system part (18) which are parts of the liquid flow system are provided on the liquid tank (2) side, and the changeover switch (26) and the battery (22) which are parts of the electrical system are provided. ) And the electrical wiring system component (28) are provided on the cover (20) side, the liquid flow system component and the electrical system component can be assembled separately, and the assembly workability becomes extremely good. The unitization of the sprayer (1) is easily achieved.

また、バッテリ(22)は、カバー(20)の下部に取り付けられていると好適である。重量物であるバッテリ(22)が噴霧機(1)の下部に配置されることで、使用中において、液体タンク(2)内の液体が少なくなったような場合でも噴霧機(1)を安定させることができる。特に、背負い式の噴霧機(1)の場合に効果的である。   The battery (22) is preferably attached to the lower part of the cover (20).

本発明によれば、部品の組付け作業性やメンテナンス性に優れた噴霧機の提供が可能になる。   ADVANTAGE OF THE INVENTION According to this invention, provision of the sprayer excellent in the assembly | attachment workability | operativity and maintenance property of components is attained.

以下、図面を参照しつつ本発明に係る噴霧機の好適な実施形態について詳細に説明する。   Hereinafter, a preferred embodiment of a sprayer according to the present invention will be described in detail with reference to the drawings.

図1に示すように、噴霧機1は、背負い式の動力噴霧機であると共に、農薬などの薬液を貯留する薬液タンク(液体タンク)2を有する。この薬液タンク2は、軽量化のために樹脂のブロー成形によって作り出されている。また、薬液タンク2の上部には樹脂製のキャップ3が螺着され、キャップ3の着脱によって薬液タンク2内に農薬などの薬液の投入・排出が可能になる。さらに、背負バンド4のフック4a,4bを引っ掛けるための穴をもったフランジ6a,6bが液体タンク2の外面に一体的に形成されている。   As shown in FIG. 1, the sprayer 1 is a shoulder-type power sprayer and has a chemical tank (liquid tank) 2 that stores chemicals such as agricultural chemicals. The chemical liquid tank 2 is produced by resin blow molding for weight reduction. Also, a resin cap 3 is screwed onto the upper part of the chemical liquid tank 2, and the chemical liquid such as agricultural chemicals can be charged and discharged into the chemical liquid tank 2 by attaching and detaching the cap 3. Further, flanges 6 a and 6 b having holes for hooking the hooks 4 a and 4 b of the back strap 4 are integrally formed on the outer surface of the liquid tank 2.

図2〜図4に示すように、薬液タンク2の背面2aには、略真ん中から下半分が切り取られたような形状の配管収容凹部8が設けられ、この配管収容凹部8は、薬液タンク2の背面2a側で開放されると共に、薬液タンク2の下端まで延長されて、薬液タンク2の全幅にわたって下側が開放されている。このような配管収容凹部8内には、電動モータ9の先端に固定された小型ポンプ10が収容され、モータ9は止め金具11によって薬液タンク2に固定されている。従って、配管収容凹部8は、薬液タンク2の下端まで延長されているので、薬液タンク2の下側から配管収容凹部8に工具を挿入することができ、電動モータ9やポンプ10は言うに及ばず、後述する配管などの部品の組み付け作業が容易になる。しかも、この噴霧機1は、メンテナンス性も要求されているので、配管収容凹部8内の部品の交換などを容易に行うことができる。   As shown in FIGS. 2 to 4, the rear surface 2 a of the chemical liquid tank 2 is provided with a pipe accommodating recess 8 having a shape such that the lower half is cut off from the middle. Is opened to the lower surface 2a side, and extended to the lower end of the chemical liquid tank 2, and the lower side is opened over the entire width of the chemical liquid tank 2. A small pump 10 fixed to the tip of the electric motor 9 is accommodated in such a pipe accommodating recess 8, and the motor 9 is fixed to the chemical liquid tank 2 by a stopper 11. Accordingly, since the pipe housing recess 8 is extended to the lower end of the chemical tank 2, a tool can be inserted into the pipe housing recess 8 from the lower side of the chemical tank 2, and the electric motor 9 and the pump 10 are not limited. Therefore, the work of assembling parts such as piping described later becomes easy. In addition, since the sprayer 1 is also required to be maintainable, it is possible to easily replace parts in the pipe housing recess 8.

さらに、ポンプ10には、薬液タンク2内の液体をポンプ10内に流入させるための吸水パイプ12の一端が接続されると共に、吐水パイプ13の一端が接続されている。この吐水パイプ13の他端は、液体の流量を調節する調圧弁14に接続され、調圧弁14には、噴霧ノズルN(図3参照)に接続された導出パイプ15の一端が接続されている。また、吐水パイプ13から導出パイプ15への流入量を調節する回動レバー式の調圧弁14には、余水パイプ16の一端が接続され、余水パイプ16の他端は薬液タンク2に接続されている。従って、吸水パイプ12と吐水パイプ13と調圧弁14と導出パイプ15と余水パイプ16とからなる配管系部品18によって、所望量の薬液を薬液タンク2から噴霧ノズルN(図3参照)に供給し続けることができる。   Further, the pump 10 is connected to one end of a water absorption pipe 12 for allowing the liquid in the chemical liquid tank 2 to flow into the pump 10 and to one end of a water discharge pipe 13. The other end of the water discharge pipe 13 is connected to a pressure regulating valve 14 that adjusts the flow rate of the liquid. The pressure regulating valve 14 is connected to one end of a lead-out pipe 15 connected to the spray nozzle N (see FIG. 3). . In addition, one end of a spill pipe 16 is connected to the rotary lever type pressure regulating valve 14 that adjusts the amount of inflow from the water discharge pipe 13 to the outlet pipe 15, and the other end of the spill pipe 16 is connected to the chemical liquid tank 2. Has been. Accordingly, a desired amount of chemical solution is supplied from the chemical solution tank 2 to the spray nozzle N (see FIG. 3) by the piping system component 18 including the water absorption pipe 12, the water discharge pipe 13, the pressure regulating valve 14, the outlet pipe 15 and the spill pipe 16. Can continue.

このような配管系部品18が取り付けられる薬液タンク2には、配管収容凹部8の開口部分を塞ぐための樹脂製のカバー20が固定され、断面L字状をなすカバー20は、ネジ19によって着脱自在に構成される。さらに、カバー20の内面側には、底壁20aに近づけられたボックス状のバッテリ収容部21が形成され、モータ9に電力を供給するバッテリ22は、バッテリ収容部21の内部に設けられた複数本のフィン23によってバッテリ収容部21内でしっかりと保持される。また、薬液タンク2側にも、バッテリ押さえ込み用の突起部24が形成され、薬液タンク2にカバー20を組み付けた後、この突起部24でバッテリ22が軽く押さえ込まれ、バッテリ22のガタ付きを防止している。   A resin cover 20 for closing the opening of the pipe housing recess 8 is fixed to the chemical tank 2 to which such a piping system component 18 is attached, and the cover 20 having an L-shaped cross section is attached and detached by a screw 19. Freely configured. Further, a box-shaped battery accommodating portion 21 that is close to the bottom wall 20 a is formed on the inner surface side of the cover 20, and a plurality of batteries 22 that supply electric power to the motor 9 are provided inside the battery accommodating portion 21. The fins 23 are firmly held in the battery housing 21. Further, a protrusion 24 for pressing the battery is formed on the chemical tank 2 side, and after the cover 20 is assembled to the chemical tank 2, the battery 22 is lightly pressed by the protrusion 24 to prevent the battery 22 from rattling. doing.

さらに、このようなバッテリ22は、重量物であるがカバー20の下部に取り付けられることになるので、バッテリ22は噴霧機1の下部に配置され、噴霧機1の使用中において、液体タンク2内の薬液が少なくなったような場合でも噴霧機1を安定させておくことができる。特に、このような構成は、背負い式の噴霧機の場合に効果的である。なお、バッテリ22は、カバー20に取付けられた蓋25(図1参照)によって外部に取り出すことができる。   Furthermore, since such a battery 22 is heavy, but is attached to the lower part of the cover 20, the battery 22 is disposed at the lower part of the sprayer 1, and the liquid tank 2 is used during the use of the sprayer 1. The sprayer 1 can be kept stable even when the amount of the chemical solution is reduced. In particular, such a configuration is effective in the case of a backpack type sprayer. The battery 22 can be taken out by a lid 25 (see FIG. 1) attached to the cover 20.

さらに、カバー20の側壁20bには、レバーによる切換スイッチ26が固定され、この切換スイッチ26はバッテリ22に電気的に接続されている。また、バッテリ収容部21の上壁21aは、薬液タンク2にカバー20を組み付けた後において、配管収容凹部8内で棚部として機能し、この棚部21aの上方には、バッテリ22からモータ9に切換スイッチ26を介して電力を供給するための電気配線系部品28が配置される。そして、この電気配線系部品28の端部にはコネクタ端子30が設けられ、このコネクタ端子30は、モータ9から延びるリード線31に設けられたコネクタ端子32に接続される。また、電気配線系部品28の一部であるバッテリチェッカ37及び充電用端子38は、カバー20の側壁20bに取付けられると共に、バッテリ22に結線されている(図1参照)。   Further, a changeover switch 26 by a lever is fixed to the side wall 20 b of the cover 20, and this changeover switch 26 is electrically connected to the battery 22. Further, the upper wall 21a of the battery housing portion 21 functions as a shelf in the pipe housing recess 8 after the cover 20 is assembled to the chemical tank 2, and the battery 22 and the motor 9 are located above the shelf 21a. An electrical wiring system component 28 for supplying power via the changeover switch 26 is arranged. A connector terminal 30 is provided at an end of the electrical wiring system component 28, and the connector terminal 30 is connected to a connector terminal 32 provided on a lead wire 31 extending from the motor 9. Further, the battery checker 37 and the charging terminal 38 which are a part of the electrical wiring system component 28 are attached to the side wall 20b of the cover 20 and connected to the battery 22 (see FIG. 1).

このようなコネクタ端子30,31を採用することで、配管収容凹部8側の配管系部品18とカバー20側の電気配線系部品28とをそれぞれ独立させることができ、配管収容凹部8内で各部品18,28が渾然となるような事態が防止される。そして、このような構成では、液体流動系統の部品をなすポンプ10及び配管系部品18が薬液タンク2側に設けられ、電気系統の部品をなす切換スイッチ26、バッテリ22及び電気配線系部品28がカバー20側に設けられているので、液体流動系統の部品と電気系統の部品とを薬液タンク2側とカバー20側とで個別にそれぞれ組み立てることができ、作業性が極めて良好になり、噴霧機1のユニット化が容易に達成される。また、カバーの側壁20cには、導出パイプ15を外部に導き出すための通孔39が設けられている。   By adopting such connector terminals 30, 31, the piping system component 18 on the piping housing recess 8 side and the electrical wiring system component 28 on the cover 20 side can be made independent of each other. A situation in which the parts 18 and 28 are stunned is prevented. In such a configuration, the pump 10 and the piping system part 18 constituting the liquid flow system parts are provided on the chemical tank 2 side, and the changeover switch 26, the battery 22 and the electrical wiring system part 28 constituting the electrical system parts are provided. Since it is provided on the cover 20 side, the parts of the liquid flow system and the parts of the electric system can be individually assembled on the chemical tank 2 side and the cover 20 side, respectively, and the workability becomes extremely good. One unitization is easily achieved. Further, a through hole 39 for leading the outlet pipe 15 to the outside is provided in the side wall 20c of the cover.

さらに、配管収容凹部8内において、ポンプ10を中央にして、配管系部品18と電気配線系部品28とが左右に振り分けられている。従って、例え配管系部品18から液漏れが発生したとしても、電気配線系部品28に薬液が付着し難く、電気的なショートが起こりにくくなり、切換スイッチ26やバッテリ22などの電気部品の損傷を可能な限り低減することができる。また、カバー20には、配管系部品18に対応する位置に矩形の視認窓33が形成されている。従って、視認窓33により、配管系部品18の液漏れ等の整備点検を可能にし、ネジ止めされたカバー20の外す回数を減らすことができるので、配管収容凹部8内へのゴミや埃の侵入を可能な限り押さえることができる。そして、この視認窓33はクッション性の背当て35によって蓋がなされ、この背当て35はカバー20の背面に着脱自在にピン止めされている。   Further, in the piping housing recess 8, the piping system component 18 and the electrical wiring system component 28 are distributed to the left and right with the pump 10 at the center. Therefore, even if liquid leakage occurs from the piping system component 18, it is difficult for the chemical solution to adhere to the electrical wiring system component 28, and electrical short-circuiting is less likely to occur, resulting in damage to electrical components such as the changeover switch 26 and the battery 22. It can be reduced as much as possible. In addition, a rectangular viewing window 33 is formed in the cover 20 at a position corresponding to the piping system component 18. Accordingly, the inspection window 33 enables maintenance and inspection such as liquid leakage of the piping system parts 18 and the number of times of removing the screwed cover 20 can be reduced, so that dust and dust enter the pipe housing recess 8. Can be suppressed as much as possible. The viewing window 33 is covered with a cushioned backrest 35, and the backrest 35 is detachably pinned to the back surface of the cover 20.

さらに、図5に示すように、配管系部品18の組み付け作業の効率化と薬液タンク2の形状の単純化を可能にするために、薬液タンク2には、配管収容凹部8に向けて突出する接続口部40が設けられ、この接続口部40には円筒状のキャップ部41が被せられている。可撓性の樹脂からなるキャップ部41は、接続口部40の外表面に密着するように押し被せられ、ホースバンド43によって抜け防止が図られている。そして、このキャップ部41は二股になっており、一方は、余水パイプ16として一体に形成され、他方は、吸水パイプ12の挿入を可能にする挿入管44としてキャップ部41に一体的に形成されている。このようなキャップ部41の採用により、配管の接続作業が容易になり、メンテナンス性に優れたユニット化が達成される。   Further, as shown in FIG. 5, in order to make the assembly work of the piping system part 18 efficient and simplify the shape of the chemical liquid tank 2, the chemical liquid tank 2 protrudes toward the pipe housing recess 8. A connection port portion 40 is provided, and the connection port portion 40 is covered with a cylindrical cap portion 41. The cap portion 41 made of a flexible resin is pressed against the outer surface of the connection port portion 40 and is prevented from coming off by the hose band 43. And this cap part 41 is bifurcated, one is integrally formed as the spill pipe 16, and the other is integrally formed in the cap part 41 as the insertion pipe 44 that allows the water absorption pipe 12 to be inserted. Has been. By adopting such a cap portion 41, pipe connection work is facilitated, and unitization with excellent maintainability is achieved.

本発明は、前述した実施形態に限定されるものではない。例えば、液体は薬液に限られない。配管収容凹部8は、液体タンク2の全幅に亘って開放されることに限定されず、液体タンク2の幅の1/2程度でも2/3程度でもよい。   The present invention is not limited to the embodiment described above. For example, the liquid is not limited to a chemical liquid. The pipe housing recess 8 is not limited to being opened over the entire width of the liquid tank 2 and may be about ½ or about 2/3 of the width of the liquid tank 2.
