Description

本発明は、搭載したバッテリからの電力供給によって駆動する携帯式の電動噴霧機に関するものである。   The present invention relates to a portable electric sprayer that is driven by power supply from a mounted battery.

農産物などに防除液などの液剤を噴霧するための携帯式の噴霧機として、電動噴霧機が知られている。背負い式などの携帯式電動噴霧機は、バッテリを搭載しており、バッテリからの電力供給によって駆動する電動ポンプによってタンク内の液剤が吐出流路を介して噴霧ノズルに圧送され、吐出流路に設けられる開閉弁を開操作することで噴霧ノズルから液剤を噴霧させる。   An electric sprayer is known as a portable sprayer for spraying a liquid agent such as a control solution on agricultural products. A portable electric sprayer such as a backpack type is equipped with a battery, and the liquid agent in the tank is pumped to the spray nozzle through the discharge flow path by an electric pump driven by the power supply from the battery, and is supplied to the discharge flow path. The liquid agent is sprayed from the spray nozzle by opening the on-off valve provided.

このような携帯式の電動噴霧機は、携帯する作業者に大きな負担がかからないように軽量化の要求が高く、重量の大きな大容量のバッテリを搭載することができない。このため、限られたバッテリ容量でできるだけ広範囲に亘って液剤を噴霧できるように、電動ポンプのスイッチ操作と開閉弁の開閉操作を連動させて、噴霧作業時にのみ電動ポンプを作動し、非作業時には電動ポンプを停止するものが知られている。   Such a portable electric sprayer has a high demand for weight reduction so that a heavy burden is not imposed on a worker who carries the portable electric sprayer, and a large-capacity battery having a large weight cannot be mounted. For this reason, the electric pump is operated only during the spraying operation in conjunction with the switch operation of the electric pump and the opening / closing operation of the on-off valve so that the liquid agent can be sprayed over the widest possible range with a limited battery capacity. What stops an electric pump is known.

ところで、携帯式の噴霧機によって噴霧される液剤には、溶解性の高いものと低いものがある。溶解性の低いものは沈殿しやすく液剤濃度が不均一になりやすいので、タンク内の液剤を攪拌することが必要になる。溶解性の程度は液剤によって様々であるため、攪拌が必要になる頻度は液剤によって一般に異なる。また、攪拌の頻度は作業の状況によっても異なる。小さい圃場が点在しているような場合や圃場内で局部的に点々と液剤散布を行うような場合は、1タンク内の液剤を噴霧し終わる間に何回か噴霧を中断することになり、噴霧を中断して移動している間に液剤が沈殿することがある。このような作業状況では噴霧を中断する毎にタンク内の液剤を攪拌することが必要になる場合がある。   By the way, the liquid agent sprayed by a portable sprayer has a high solubility and a low solubility. Those having low solubility tend to precipitate, and the concentration of the liquid agent is likely to be non-uniform, so it is necessary to stir the liquid agent in the tank. Since the degree of solubility varies depending on the liquid agent, the frequency with which stirring is required generally varies depending on the liquid agent. In addition, the frequency of stirring varies depending on the work situation. When small farms are scattered or when spraying liquids locally in the field, spraying is interrupted several times while spraying the liquid in one tank. In some cases, the liquid may precipitate while moving while spraying is interrupted. In such work situations, it may be necessary to agitate the liquid agent in the tank every time spraying is interrupted.

また、タンク内の液剤の攪拌は、液剤濃度を均一に保つためだけで無く、残液の排水時にも必要になる。タンク内の残液を排水処理する場合には、沈殿した高濃度の液剤成分がタンクの底部に固着してしまうのを避けるために、残液を攪拌して液剤成分をできるだけ均一に溶かして排水することが好ましい。   Further, stirring of the liquid agent in the tank is necessary not only for keeping the liquid agent concentration uniform, but also when draining the residual liquid. When draining the residual liquid in the tank, in order to avoid the settled high concentration liquid component from sticking to the bottom of the tank, the residual liquid is stirred to dissolve the liquid component as uniformly as possible. It is preferable to do.

このように携帯式の噴霧機は、噴霧する液剤の種類によってはタンク内に貯留した液剤を攪拌することが必要になるが、攪拌のための装置(攪拌羽根など)を別途備えることは携帯式噴霧機に求められる軽量化の要求に反することになるので好ましくない。携帯式の噴霧機において軽量化の要求に応えながら攪拌機能を持たせるものとしては、余水循環によって攪拌を行うものが知られている。携帯式電動噴霧機においては、前述したようにバッテリ容量を制限せざるを得ないので、噴霧停止時に常時余水循環することは避けるべきである。下記特許文献1に記載された携帯式の電動噴霧機は、必要時にのみ余水循環によるタンク内の攪拌を行うことができるものである。   As described above, the portable sprayer needs to stir the liquid stored in the tank depending on the type of the liquid to be sprayed, but it is portable to separately include a device for stirring (such as a stirring blade). This is not preferable because it is contrary to the requirement for weight reduction required for the sprayer. As a portable sprayer that has a stirring function while meeting the demand for weight reduction, one that performs stirring by circulating residual water is known. In the portable electric sprayer, the battery capacity must be limited as described above, and therefore, it is necessary to avoid the circulation of the remaining water at all times when spraying is stopped. The portable electric sprayer described in the following Patent Document 1 can perform stirring in the tank by circulating the remaining water only when necessary.

下記特許文献1に記載の従来技術は、電動噴霧機のコック装置であって、吐出流路を開閉する開閉弁の開閉操作部材と吐出流路に液剤を供給する電動ポンプのスイッチとを操作機構上互いに連係させ、操作者の一連の操作で電動ポンプが始動した後に開閉弁が開くようにしている。また、コック装置のコックレバーに第1の操作位置と第2の操作位置を設け、第1の操作位置では開閉弁が閉じた状態で電動ポンプを作動させて、余水流路を介して液剤をタンクに戻すことでタンク内の攪拌を行い、第2の操作位置では電動ポンプを作動させた状態で開閉弁を開いて液剤を噴霧させることが行われている。   The prior art described in the following Patent Document 1 is a cock device for an electric sprayer, and includes an opening / closing operation member for an opening / closing valve for opening / closing the discharge passage and an electric pump switch for supplying a liquid agent to the discharge passage. The on-off valve is opened after the electric pump is started by a series of operations by the operator. In addition, the cock lever of the cock device is provided with a first operation position and a second operation position, and at the first operation position, the electric pump is operated with the on-off valve closed, and the liquid agent is supplied via the spill passage. The tank is agitated by returning to the tank, and at the second operation position, the on-off valve is opened and the liquid agent is sprayed with the electric pump operated.

特開2003−24833号公報JP 2003-24833 A

このような従来の電動噴霧機によると、コックレバーの操作によって吐出流路の開閉弁の開閉操作と電動ポンプのスイッチ操作を連係させてはいるものの、操作者が誤ってコックレバーを第1の操作位置にしたまま放置すると、無用なタンク内の攪拌が継続されてバッテリ電力が無駄に消費されてしまうことになる。また、噴霧作業の一時的な中断時には、操作者は第1の操作位置を意識しないで第2の操作位置までレバー操作を行ってしまう場合があり、一時的な噴霧作業の中断時に攪拌が必要になる場合に、十分な攪拌を行うこと無く噴霧を行ってしまう問題があった。   According to such a conventional electric sprayer, although the opening / closing operation of the opening / closing valve of the discharge passage and the switch operation of the electric pump are linked by the operation of the cock lever, the operator mistakenly operates the first cock lever. If left in the operation position, unnecessary stirring in the tank is continued and battery power is wasted. Further, when the spraying operation is temporarily interrupted, the operator may operate the lever to the second operation position without being aware of the first operation position, and stirring is necessary when the spraying operation is temporarily interrupted. In this case, there is a problem that spraying is performed without sufficient stirring.

また、適正な攪拌の頻度は、前述したように噴霧する液剤の種類や噴霧作業の状況によって異なるが、前述した従来技術では、攪拌の頻度をどの程度にするかが操作者のコックレバー操作に任されており、噴霧作業を一時停止した場合などに操作者は攪拌操作を行うかどうかの判断を常に強いられる。このため、操作者が噴霧作業に集中できなくなる問題が生じる。   In addition, the appropriate stirring frequency varies depending on the type of liquid to be sprayed and the state of the spraying work as described above, but in the conventional technology described above, how much the stirring frequency is set depends on the operator's cock lever operation. Therefore, when the spraying operation is temporarily stopped, the operator is always forced to determine whether or not to perform the stirring operation. For this reason, the problem that an operator cannot concentrate on spraying work arises.

また、タンクや吐出流路のメンテナンス時や清掃時に行う余水循環、あるいは液剤排水時の攪拌は、開閉弁を閉じた状態を維持して行う必要があるが、前述した従来技術によると、攪拌状態がコック開閉弁の中間に設けられているため、作業者がコックレバーの停止位置を誤ると開閉弁が開いてしまい、不要な噴霧となる可能性があった。   In addition, sewage circulation performed during maintenance and cleaning of the tank and discharge channel, or stirring during drainage of the liquid agent must be performed with the on-off valve closed. Is provided in the middle of the cock opening / closing valve, and if the operator makes a mistake in the stop position of the cock lever, the opening / closing valve opens, which may cause unnecessary spraying.

本発明は、このような従来技術の問題を改善することを課題とするものである。すなわち、攪拌動作の継続を設定時間で停止させることでバッテリ電力の浪費を無くすこと、噴霧作業の一時的な中断時などでも確実に攪拌動作を行うことができること、攪拌が必要な場合にも操作者が噴霧作業に集中できるようにすること、タンクや吐出流路のメンテナンスや清掃時の余水循環時、あるいは液剤排水時の攪拌時などに、不要な噴霧が行われないようにすること、などが本発明の目的である。   An object of the present invention is to improve such problems of the prior art. In other words, it is possible to eliminate the waste of battery power by stopping the continuation of the agitation operation at the set time, to ensure that the agitation operation can be performed even when the spraying operation is temporarily interrupted, and to operate even when agitation is necessary To allow the user to concentrate on spraying work, to prevent unnecessary spraying during maintenance of the tank and discharge flow path, circulation of residual water during cleaning, or stirring during liquid drainage, etc. Is the object of the present invention.

このような目的を達成するために、本発明による携帯式電動噴霧機は、以下の構成を少なくとも具備するものである。
携帯式のフレームと、該フレームに搭載されるバッテリと、前記バッテリの電力によって駆動する電動ポンプと、前記フレームが備えるタンクと、前記電動ポンプの作動によって前記タンク内の液剤が吐出される吐出流路と、前記吐出流路の端部に設けられる噴霧ノズルと、前記吐出流路を開閉する開閉弁と、前記開閉弁の閉止時に前記吐出流路を流れる液剤を前記タンク内に戻す余水流路と、前記バッテリの電力を前記電動ポンプに供給制御する制御部とを備え、前記制御部は、前記開閉弁の開閉操作に連動して、前記開閉弁の開状態での第1接点と前記開閉弁の閉状態での第2接点を切り換える開閉弁連動スイッチと、前記開閉弁連動スイッチの前記第2接点切り換え時に、前記電動ポンプへの電力供給を設定時間継続して余水による攪拌動作を行う攪拌動作スイッチを備えることを特徴とする。
In order to achieve such an object, a portable electric sprayer according to the present invention comprises at least the following configuration.
A portable frame, a battery mounted on the frame, an electric pump driven by the electric power of the battery, a tank provided in the frame, and a discharge flow in which liquid in the tank is discharged by the operation of the electric pump A spray nozzle provided at an end of the discharge flow path, an on-off valve that opens and closes the discharge flow path, and a spillage flow path that returns the liquid that flows through the discharge flow path to the tank when the open / close valve is closed And a control unit that controls supply of electric power of the battery to the electric pump, and the control unit interlocks with an opening / closing operation of the opening / closing valve to open and close the first contact and the opening / closing of the opening / closing valve. An on / off valve interlock switch for switching the second contact in the closed state of the valve, and at the time of switching the second contact of the on / off valve interlock switch, the electric power supply to the electric pump is continued for a set time and is stirred by residual water. Characterized in that it comprises a stirring operation switch for operating.

このような特徴を有する携帯式電動噴霧機は、開閉弁と連動する開閉弁連動スイッチによって開閉弁開放時に電動ポンプへの電力供給を行い、開閉弁閉止時に電動ポンプへの電力供給を遮断することができ、また、開閉弁が閉状態になる開閉弁連動スイッチの第2接点切り換え時に電動ポンプへの電力供給を設定時間継続して余水による攪拌動作を行う攪拌動作スイッチを備える。これによって、攪拌動作の継続を設定時間で停止させることでバッテリ電力の浪費を無くすことができる。   A portable electric sprayer having such characteristics is to supply power to the electric pump when the on / off valve is open and to shut off the power supply to the electric pump when the on / off valve is closed by the on / off valve interlocking switch linked to the on / off valve. And an agitation operation switch that performs an agitation operation with residual water by continuing power supply to the electric pump for a set time when the second contact point of the on / off valve interlocking switch that closes the on / off valve is switched. Thereby, waste of battery power can be eliminated by stopping the continuation of the stirring operation at the set time.

また、攪拌動作スイッチは、自動攪拌動作モードを選択することができ、これによると噴霧作業の一時的な中断時などでも確実に攪拌動作を行うことができると共に、噴霧作業の中断毎に攪拌を行うか否かの判断を操作者に強いることが無い。また、開閉弁の開閉操作に連動した開閉弁連動スイッチと攪拌動作スイッチとを別に構成し、開閉弁の閉止時にのみ攪拌動作を可能にしているので、攪拌動作時に開閉弁が開かれることがなく、タンクや吐出流路のメンテナンスや清掃時などの余水循環時に不要な噴霧が行われることがない。   In addition, the agitation operation switch can select the automatic agitation operation mode, which can reliably perform the agitation operation even when the spraying operation is temporarily interrupted, and performs the agitation every time the spraying operation is interrupted. There is no need to force the operator to decide whether or not to do so. In addition, the on / off valve interlocking switch linked to the opening / closing operation of the on / off valve and the agitation operation switch are configured separately to enable the agitation operation only when the on / off valve is closed, so that the on / off valve is not opened during the agitation operation Unnecessary spraying is not performed during sewage circulation such as during maintenance and cleaning of the tank and discharge flow path.

以下、図面を参照して本発明の実施形態を説明する。図1は本発明の一実施形態に係る携帯式電動噴霧機の全体構成を示した説明図である。携帯式電動噴霧機1は、背負いバンド10Aを備える携帯式のフレーム10を備える。以下の説明では背負い式を例に説明するが本発明の実施形態は特に背負い式に限らない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing the overall configuration of a portable electric sprayer according to an embodiment of the present invention. The portable electric sprayer 1 includes a portable frame 10 including a shoulder band 10A. In the following description, the backpack type will be described as an example, but the embodiment of the present invention is not limited to the backpack type.

フレーム10には、防除液などの液剤が充填されるタンク11と、ケーシング12が搭載されており、ケーシング12内には、バッテリ13、バッテリ13の電力によって駆動する電動ポンプ14、電動ポンプ14の駆動源であるモータ15が搭載されている。電動ポンプ14に接続される吐出流路には、可撓性ホース16と導液管17が設けられ、導液管17の先端には噴霧ノズル18が設けられている。また、導液管17と可撓性ホース16の接続部にはハンドル部19と操作部20が設けられ、操作部20には、吐出流路を開閉する開閉弁を操作する操作レバー20Aが設けられる。   The frame 10 is equipped with a tank 11 filled with a liquid agent such as a control liquid and a casing 12. The casing 12 includes a battery 13, an electric pump 14 driven by the electric power of the battery 13, and an electric pump 14. A motor 15 as a drive source is mounted. The discharge flow path connected to the electric pump 14 is provided with a flexible hose 16 and a liquid guide pipe 17, and a spray nozzle 18 is provided at the tip of the liquid guide pipe 17. Further, a handle portion 19 and an operation portion 20 are provided at a connection portion between the liquid introduction pipe 17 and the flexible hose 16, and an operation lever 20A for operating an on-off valve that opens and closes the discharge flow path is provided at the operation portion 20. It is done.

図2は、携帯式電動噴霧機1の流路系と電気系を示した説明図である。携帯式電動噴霧機1の流路系は、一点破線で図示するように、電動ポンプ14の作動によってタンク11内の液剤が吐出される吐出流路22と、吐出流路22を開閉する開閉弁21と、開閉弁21の閉止時に吐出流路22を流れる液剤をタンク11内に戻す余水流路23を備えており、吐出流路22の端部に噴霧ノズル18が設けられる。余水流路23には必要に応じて調圧弁24が設けられる。   FIG. 2 is an explanatory view showing a flow path system and an electric system of the portable electric sprayer 1. The flow path system of the portable electric sprayer 1 includes a discharge flow path 22 through which the liquid agent in the tank 11 is discharged by the operation of the electric pump 14 and an on-off valve that opens and closes the discharge flow path 22 as illustrated by a one-dot broken line. 21 and a spill passage 23 for returning the liquid agent flowing through the discharge passage 22 into the tank 11 when the on-off valve 21 is closed, and a spray nozzle 18 is provided at the end of the discharge passage 22. A pressure regulating valve 24 is provided in the spill passage 23 as required.

携帯式電動噴霧機1の電気系は、バッテリ13の電力を電動ポンプ14のモータ15に供給制御する制御部30によって構成される。制御部30は、開閉弁連動スイッチ31と、攪拌動作スイッチ32と、メインスイッチ33と、制御手段(モード切り替え制御手段)34を備えており、必要に応じて、渇水停止手段35、回転制御手段36を備えている。   The electric system of the portable electric sprayer 1 is configured by a control unit 30 that controls supply of electric power from the battery 13 to the motor 15 of the electric pump 14. The control unit 30 includes an on-off valve interlocking switch 31, a stirring operation switch 32, a main switch 33, and a control means (mode switching control means) 34. If necessary, a drought stop means 35, a rotation control means. 36.

開閉弁連動スイッチ31は、開閉弁21の開閉操作に連動して、開閉弁21の開状態での第1接点31Aと開閉弁21の閉状態での第2接点31Bを切り換えるスイッチである。開閉弁連動スイッチ31は、開閉弁21を操作する操作部20の操作レバー20Aによって第1接点31Aと第2接点31Bの切り換え操作がなされ、開閉弁21を開放操作することで開閉弁連動スイッチ31は第1接点31Aに切り換えられ、開閉弁21を閉止操作することで第2接点31Bに切り換えられる。また、開閉弁連動スイッチ31は、開閉弁21の開閉操作に伴う状態変化の検知(例えば、吐出流路22に設定した圧力センサの検知信号)に基づいて第1接点31Aと第2接点31Bの切り替えを行うものであってもよい。   The on-off valve interlock switch 31 is a switch that switches between the first contact 31A when the on-off valve 21 is open and the second contact 31B when the on-off valve 21 is closed in conjunction with the opening / closing operation of the on-off valve 21. The on / off valve interlocking switch 31 is switched between the first contact 31A and the second contact 31B by the operation lever 20A of the operating unit 20 for operating the on / off valve 21. By opening the on / off valve 21, the on / off valve interlocking switch 31 is operated. Is switched to the first contact 31A, and is switched to the second contact 31B by closing the on-off valve 21. The on-off valve interlocking switch 31 is configured to detect the state of the first contact 31A and the second contact 31B based on detection of a state change accompanying the opening / closing operation of the on-off valve 21 (for example, a detection signal of a pressure sensor set in the discharge passage 22). Switching may be performed.

攪拌動作スイッチ32は、開閉弁連動スイッチ31の第2接点接続時に、電動ポンプ14のモータ15への電力供給を設定時間継続して余水による攪拌動作を行う機能を有する。開閉弁連動スイッチ31の第2接点接続時に攪拌動作スイッチ32が操作されると、後述する動作モードの各条件に応じて、開閉弁21を閉止した状態で設定時間だけモータ15をON状態にして電動ポンプ14を駆動させる。これによって、電動ポンプ14によって吐出された液剤は余水流路23を通ってタンク11内に戻され、この余水戻りによってタンク11内の液剤が攪拌されることになる。   The stirring operation switch 32 has a function of continuing the power supply to the motor 15 of the electric pump 14 for a set time and performing a stirring operation with residual water when the on-off valve interlock switch 31 is connected to the second contact. When the agitation operation switch 32 is operated when the second contact point of the on / off valve interlocking switch 31 is connected, the motor 15 is turned on for a set time with the on / off valve 21 closed according to each condition of an operation mode to be described later. The electric pump 14 is driven. Thereby, the liquid agent discharged by the electric pump 14 is returned to the tank 11 through the spill passage 23, and the liquid agent in the tank 11 is agitated by this spill return.

攪拌動作スイッチ32は、攪拌動作の複数の動作モードを切り換えるモード切り替えスイッチ32Aを含んでいる。図示の例では、モード切り替えスイッチ32Aは4つの端子を選択的に切り換えることができ、選択された各端子に応じて動作モードA,動作モードB,動作モードC,動作モードDが選択されることになる。ここでは、一例として4つの動作モードを示しているが、選択される動作モードの設定数は任意である。また、これらの動作モードには攪拌動作を行わない動作モードを含めることができる。   The stirring operation switch 32 includes a mode changeover switch 32A that switches a plurality of operation modes of the stirring operation. In the illustrated example, the mode changeover switch 32A can selectively switch four terminals, and the operation mode A, the operation mode B, the operation mode C, and the operation mode D are selected according to each selected terminal. become. Here, four operation modes are shown as an example, but the number of operation modes to be selected is arbitrary. These operation modes can include an operation mode in which the stirring operation is not performed.

制御手段(モード切り替え制御手段)34は、モード切り替えスイッチ32Aによって選択された動作モードでモータ15への電力供給を制御する。制御手段34は、メインスイッチ33のON・OFF信号、開閉弁連動スイッチ31の切り換え信号に応じて、選択された動作モードに対応した攪拌動作の制御を行う。   The control means (mode change control means) 34 controls the power supply to the motor 15 in the operation mode selected by the mode change switch 32A. The control means 34 controls the stirring operation corresponding to the selected operation mode in accordance with the ON / OFF signal of the main switch 33 and the switching signal of the on-off valve interlocking switch 31.

具体的な動作モードの例は後述するが、一つの動作モードは、メインスイッチ33起動時に電動ポンプ14のモータ15への電力供給を設定時間継続する初期攪拌動作を行う動作モードを含む。また一つの動作モードは、開閉弁連動スイッチ31を第1接点31Aから第2接点31Bに切り換えた後に電動ポンプ14のモータ15への電力供給を設定時間継続する中断時攪拌動作を行う動作モードを含む。ここでの初期攪拌動作とは、噴霧ノズル18から液剤を噴霧する噴霧動作に先立って、前述した攪拌動作を行うものであり、中断時攪拌動作とは、噴霧動作の中断時に前述した攪拌動作を行うものである。いずれの攪拌動作も設定された時間だけ攪拌動作を行った後モータ15への電力供給を遮断する。   Although an example of a specific operation mode will be described later, one operation mode includes an operation mode in which an initial stirring operation is performed in which power supply to the motor 15 of the electric pump 14 is continued for a set time when the main switch 33 is activated. One operation mode is an operation mode in which the agitation operation during interruption is performed in which the power supply to the motor 15 of the electric pump 14 is continued for a set time after the on-off valve interlock switch 31 is switched from the first contact 31A to the second contact 31B. Including. The initial stirring operation here is to perform the above-described stirring operation prior to the spraying operation of spraying the liquid agent from the spray nozzle 18, and the stirring operation at the time of interruption refers to the stirring operation described above when the spraying operation is interrupted. Is what you do. In any stirring operation, the stirring operation is performed for a set time, and then the power supply to the motor 15 is cut off.

図3〜図6は、制御手段が実行する動作モードの具体例を示した動作フローである。図3は、動作モードAの動作フローを示している。モード切り替えスイッチ32Aによって動作モードAが選択された場合には、制御手段34はメインスイッチ33がONになるのを待ち(A1−「NO」)、メインスイッチ33がONになると(A1−「YES」)、開閉弁連動スイッチ31が第2接点31Bに切り換えられていること(開閉弁21が閉じていること)を確認する(A2)。開閉弁連動スイッチ31が第2接点31Bに切り換えられていない場合(開閉弁21が開いている場合)には(A2−「NO」)、アラームを発して操作レバー20Aによって開閉弁21を閉じる(開閉弁連動スイッチ31を第2接点31Bに切り換える)ように促す(A3)。そして、開閉弁連動スイッチ31が第2接点31Bに切り換えられていることを確認すると(A2−「YES」)、初期攪拌動作を実行する(A4)。初期攪拌動作は、制御手段34が備えるタイマー機能によって、設定される時間だけモータ15を動作させて、余水の循環でタンク11内の液剤を攪拌する。   3 to 6 are operation flows showing specific examples of operation modes executed by the control means. FIG. 3 shows an operation flow of the operation mode A. When the operation mode A is selected by the mode changeover switch 32A, the control unit 34 waits for the main switch 33 to be turned on (A1- "NO"), and when the main switch 33 is turned on (A1- "YES" ]), It is confirmed that the on-off valve interlocking switch 31 is switched to the second contact 31B (the on-off valve 21 is closed) (A2). When the on-off valve interlock switch 31 is not switched to the second contact 31B (when the on-off valve 21 is open) (A2- "NO"), an alarm is generated and the on-off valve 21 is closed by the operation lever 20A ( It is urged to switch the on / off valve interlocking switch 31 to the second contact 31B (A3). And if it confirms that the on-off valve interlocking switch 31 is switched to the 2nd contact 31B (A2- "YES"), an initial stirring operation will be performed (A4). In the initial stirring operation, the motor 15 is operated for a set time by the timer function provided in the control means 34, and the liquid agent in the tank 11 is stirred by circulation of the remaining water.

初期攪拌動作が行われた後、開閉弁連動スイッチ31が第1接点31Aに切り換えられる(開閉弁21が開放される)のを待ち(A5−「NO」)、開閉弁連動スイッチ31が第1接点31Aに切り換えられると(A5−「YES」)、モータ15をONにして噴霧動作を行う(A6)。開閉弁連動スイッチ31は操作部20の操作レバー20Aによって第1接点31Aと第2接点31Bの切り換えが操作され、開閉弁連動スイッチ31が第1接点31Aに切り換えられるとそれに連動して開閉弁21が開放されて噴霧が行われる。噴霧動作は開閉弁連動スイッチ31が第2接点31Bに切り換えられるまで継続され(A7−「NO」)、開閉弁連動スイッチ31が第2接点31Bに切り換えられると(A7−「YES」)、モータ15をOFFにして噴霧を停止する(A8)。その後は、メインスイッチ33がOFFになるまで(A9−「NO」)開閉弁連動スイッチ31の第1接点31Aへの切り換え待ち状態になり(A5−「NO」)、メインスイッチ33がOFFになると(A9−「YES」)、この動作モードを終了する。   After the initial stirring operation is performed, it waits for the on-off valve interlock switch 31 to be switched to the first contact 31A (the on-off valve 21 is opened) (A5- "NO"), and the on-off valve interlock switch 31 is in the first position. When switched to the contact 31A (A5- "YES"), the motor 15 is turned on to perform the spraying operation (A6). The on / off valve interlock switch 31 is operated by the operation lever 20A of the operation unit 20 to switch between the first contact 31A and the second contact 31B, and when the on / off valve interlock switch 31 is switched to the first contact 31A, the on / off valve 21 is interlocked therewith. Is opened and spraying is performed. The spraying operation is continued until the on-off valve interlocking switch 31 is switched to the second contact 31B (A7- “NO”), and when the on-off valve interlocking switch 31 is switched to the second contact 31B (A7— “YES”), the motor is operated. 15 is turned off to stop spraying (A8). Thereafter, until the main switch 33 is turned off (A9- “NO”), the on-off valve interlocking switch 31 waits for switching to the first contact 31A (A5- “NO”), and when the main switch 33 is turned off. (A9- "YES"), this operation mode is terminated.

このように動作モードAは、メインスイッチ33がONになった後の初期攪拌動作を行い、その後には攪拌動作を行わない動作モードである。この動作モードAは、頻繁に攪拌を行う必要が無い溶解性の高い液剤を用いる場合に有効である。メインスイッチ33がONに操作される毎に自動で攪拌動作が行われることになるので、操作者は攪拌を行うか否か判断する煩雑さから解消され、液剤噴霧作業に集中することができる。   As described above, the operation mode A is an operation mode in which the initial stirring operation after the main switch 33 is turned on is performed, and thereafter the stirring operation is not performed. This operation mode A is effective when a highly soluble liquid that does not require frequent stirring is used. Since the stirring operation is automatically performed every time the main switch 33 is turned on, the operator is free from the trouble of determining whether or not to perform stirring, and can concentrate on the liquid spraying operation.

図4は、動作モードBの動作フローを示している。モード切り替えスイッチ32Aによって動作モードBが選択された場合に制御手段34によって動作モードBが実行される。動作モードBのステップB1〜B8までは動作モードAにおけるステップA1〜A8と同様である。   FIG. 4 shows an operation flow of the operation mode B. When the operation mode B is selected by the mode changeover switch 32A, the operation mode B is executed by the control means 34. Steps B1 to B8 in the operation mode B are the same as steps A1 to A8 in the operation mode A.

噴霧動作継続中に開閉弁連動スイッチ31が第2接点31Bに切り換えられると、中断時攪拌動作が実行される(B9。)中断時攪拌動作は、噴霧動作の一次中断時に攪拌動作を行うもので、開閉弁連動スイッチ31が第2接点31Bに切り換えられてモータ15が停止された後、第1設定時間T1s後に第2設定時間T2sだけモータ15をONにして攪拌動作を行う。この際の第1設定時間T1sと第2設定時間T2sは任意に設定可能である。第1設定時間を0sにして、開閉弁連動スイッチ31がOFFになった直後から第2設定時間T2sだけモータ15のON状態を継続するようにしてもよい。逆に、沈殿しにくい液剤であれば、第1設定時間を長く設定するのがよい。   When the on-off valve interlocking switch 31 is switched to the second contact 31B while the spraying operation is continued, the stirring operation at the time of interruption is executed (B9). The stirring operation at the time of interruption performs the stirring operation at the primary interruption of the spraying operation. After the on / off valve interlocking switch 31 is switched to the second contact 31B and the motor 15 is stopped, the stirring operation is performed by turning on the motor 15 for the second set time T2s after the first set time T1s. At this time, the first set time T1s and the second set time T2s can be arbitrarily set. The first set time may be set to 0 s, and the ON state of the motor 15 may be continued for the second set time T2 s immediately after the on-off valve interlock switch 31 is turned off. Conversely, if the liquid agent is difficult to precipitate, the first setting time should be set longer.

その後は、動作モードAと同様に、メインスイッチ33がOFFになるまで(B10−「NO」)開閉弁連動スイッチ31の第1接点31Aへの切り換え待ち状態になり(B5−「NO」)、メインスイッチ33がOFFになると(B10−「YES」)、この動作モードを終了する。   Thereafter, as in the operation mode A, until the main switch 33 is turned off (B10- “NO”), the on-off valve interlocking switch 31 waits for switching to the first contact 31A (B5- “NO”). When the main switch 33 is turned off (B10— “YES”), this operation mode is terminated.

このように動作モードBは、メインスイッチ33がONになった後に初期攪拌動作を行い、その後は、噴霧動作の中断毎に中断時攪拌動作を行うものである。この動作モードBは、頻繁に攪拌を行う必要がある溶解性の低い液剤を用いる場合に有効である。メインスイッチ33がONに操作される毎に自動で初期攪拌動作が行われ、噴霧動作が中断される毎に自動で中断時攪拌動作が行われることになるので、操作者は噴霧動作の中断毎に攪拌を行うか否か判断する煩雑さから解消され、液剤噴霧作業に集中することができる。   As described above, in the operation mode B, the initial stirring operation is performed after the main switch 33 is turned on, and thereafter, the suspension stirring operation is performed every time the spraying operation is interrupted. This operation mode B is effective when using a low-solubility liquid agent that needs to be frequently stirred. Every time the main switch 33 is turned ON, the initial stirring operation is automatically performed, and every time the spraying operation is interrupted, the interrupting stirring operation is automatically performed. Therefore, it is possible to concentrate on the liquid agent spraying work.

図5は、動作モードCの動作フローを示している。モード切り替えスイッチ32Aによって動作モードCが選択された場合に制御手段34によって動作モードCが実行される。動作モードCでは、メインスイッチ33の待機状態(C1−「NO」)からメインスイッチ33がONになると(C1−「YES」)、開閉弁連動スイッチ31の待機状態になり(C2−「NO」)、開閉弁連動スイッチ31が第1接点31Aに切り換えられるとモータ15がONになって噴霧動作が行われる(C3)。噴霧動作は開閉弁連動スイッチ31が第2接点31Bに切り換えられるまで継続され(C4−「NO」)、開閉弁連動スイッチ31が第2接点31Bに切り換えられると(C4−「YES」)、モータ15をOFFにして噴霧動作を停止する(C5)。その後、動作モードBと同様の中断時攪拌動作を実行する(C6)。その後は、動作モードA,Bと同様に、メインスイッチ33がOFFになるまで(C7−「NO」)開閉弁連動スイッチ31の第1接点31Aの切り換え待ち状態になり(C2−「NO」)、メインスイッチ33がOFFになると(C7−「YES」)、この動作モードを終了する。   FIG. 5 shows an operation flow of the operation mode C. When the operation mode C is selected by the mode switch 32A, the operation mode C is executed by the control means 34. In the operation mode C, when the main switch 33 is turned on from the standby state of the main switch 33 (C1- “NO”) (C1- “YES”), the on-off valve interlock switch 31 is in a standby state (C2- “NO”). ) When the on-off valve interlocking switch 31 is switched to the first contact 31A, the motor 15 is turned on and the spraying operation is performed (C3). The spraying operation is continued until the on-off valve interlock switch 31 is switched to the second contact 31B (C4- "NO"), and when the on-off valve interlock switch 31 is switched to the second contact 31B (C4- "YES"), the motor is operated. 15 is turned off to stop the spraying operation (C5). Then, the suspension stirring operation similar to the operation mode B is executed (C6). After that, as in the operation modes A and B, until the main switch 33 is turned off (C7- “NO”), the first contact 31A of the on-off valve interlocking switch 31 is waited for switching (C2- “NO”). When the main switch 33 is turned off (C7— “YES”), this operation mode is terminated.

このように動作モードCは、初期攪拌動作を行うこと無く、噴霧動作の中断毎に中断時攪拌動作を行うものである。動作モードBと動作モードCの変形例としては、噴霧動作の中断毎に毎回中断時攪拌動作を行うのではなく、噴霧動作の中断回数をカウントして設定回数の中断毎に中断時攪拌動作を行うようにすることもできる。この動作モードCは、比較的頻繁に攪拌を行う必要がある溶解性のやや低い液剤を用いる場合、あるいは噴霧作業が頻繁に中断する可能性がある作業状況の際に有効である。噴霧動作が中断される毎、あるいは複数回の中断毎に自動で中断時攪拌動作が行われることになるので、操作者は噴霧動作の中断毎に攪拌を行うか否かを判断する煩雑さから解消され、液剤噴霧作業に集中することができる。   As described above, in the operation mode C, the agitation operation during interruption is performed every time the spraying operation is interrupted without performing the initial agitation operation. As a modified example of the operation mode B and the operation mode C, instead of performing the stirring operation at every interruption of the spraying operation every time the spraying operation is interrupted, the number of times the spraying operation is interrupted is counted and the stirring operation at the interruption is performed every interruption of the set number of times You can also do it. This operation mode C is effective in the case of using a solution having a slightly low solubility that needs to be stirred relatively frequently, or in a work situation where the spraying work may be frequently interrupted. When the spraying operation is interrupted or every time when the spraying operation is interrupted, the suspension stirring operation is automatically performed. Therefore, the operator has to judge whether to perform the stirring every time the spraying operation is interrupted. Eliminates and concentrates on liquid spraying.

図6は、動作モードDの動作フローを示している。モード切り替えスイッチ32Aによって動作モードDが選択された場合に制御手段34によって動作モードDが実行される。動作モードDでは、メインスイッチ33の待機状態(D1−「NO」)からメインスイッチ33がONになると(D1−「YES」)、モータ15がONになり強制攪拌動作が実行される(D2)。その後、開閉弁連動スイッチ31の待機状態になり(D3−「NO」)、開閉弁連動スイッチ31が第1接点31Aに切り換えられると(D3−「YES」)開閉弁21が開放されて噴霧動作が行われる。その後、開閉弁連動スイッチ31が第2接点31Bに切り換えられるまで噴霧動作が継続され(D5−「NO」)、開閉弁連動スイッチ31が第2接点31Bに切り換えられると(D5−「YES」)、再び強制攪拌動作に移行する。その後、メインスイッチ33がOFFになるまで(D7−「NO」)開閉弁連動スイッチ31の第1接点31Aへの切り換え待ち状態になり(D3−「NO」)、メインスイッチ33がOFFになると(D7−「YES」)、モータ15をOFFにして(D8)、この動作モードを終了する。   FIG. 6 shows an operation flow of the operation mode D. When the operation mode D is selected by the mode changeover switch 32A, the operation mode D is executed by the control means 34. In the operation mode D, when the main switch 33 is turned on from the standby state (D1- “NO”) of the main switch 33 (D1- “YES”), the motor 15 is turned on and the forced stirring operation is executed (D2). . Thereafter, the on-off valve interlock switch 31 enters a standby state (D3- “NO”), and when the on-off valve interlock switch 31 is switched to the first contact 31A (D3- “YES”), the on-off valve 21 is opened and spraying operation is performed. Is done. Thereafter, the spraying operation is continued until the on-off valve interlock switch 31 is switched to the second contact 31B (D5- "NO"), and when the on-off valve interlock switch 31 is switched to the second contact 31B (D5- "YES"). Then, the operation again moves to the forced stirring operation. After that, until the main switch 33 is turned off (D7— “NO”), the on-off valve interlocking switch 31 waits for switching to the first contact 31A (D3- “NO”), and when the main switch 33 is turned off ( D7— “YES”), the motor 15 is turned off (D8), and this operation mode is terminated.

この動作モードDは、メインスイッチ33のON・OFFでモータ15がON・OFFされることになり、メインスイッチ33がONの状態では開閉弁連動スイッチ31の切り換え操作を無視してモータ15のON状態を継続する。この動作モードDは、タンク11や吐出流路22,余水流路23の清掃やメンテナンス時に適する動作モードである。   In this operation mode D, the motor 15 is turned ON / OFF by turning the main switch 33 ON / OFF. When the main switch 33 is ON, the switching operation of the on-off valve interlocking switch 31 is ignored and the motor 15 is turned ON. Continue state. This operation mode D is an operation mode suitable for cleaning and maintenance of the tank 11, the discharge channel 22, and the spillage channel 23.

以上説明したような携帯式電動噴霧機1によると、攪拌動作を行う際に設定された時間で電動ポンプ14を自動停止させることができるので、作業者が攪拌動作を停止し忘れた場合にも過剰なバッテリ電力の浪費を回避することができる。また、攪拌動作の動作モードを選択できるので、タンク11内の液剤の種類や噴霧動作の作業状況などに応じて、適正な攪拌動作の態様を選択することができる。また、攪拌動作スイッチ32は攪拌動作を行わないことを選択することもでき、これによると開閉弁連動スイッチ31によって噴霧時のみに電動ポンプ14を駆動させることができるので、バッテリ電力の消費を最小限に抑えることができる。   According to the portable electric sprayer 1 as described above, since the electric pump 14 can be automatically stopped at the time set when the stirring operation is performed, even when the operator forgets to stop the stirring operation. Excessive battery power waste can be avoided. Further, since the operation mode of the stirring operation can be selected, it is possible to select an appropriate mode of the stirring operation according to the type of the liquid agent in the tank 11 and the working state of the spraying operation. Further, the stirring operation switch 32 can be selected not to perform the stirring operation. According to this, since the electric pump 14 can be driven only by the on-off valve interlocking switch 31 during spraying, battery power consumption is minimized. To the limit.
