Description

【０００１】
【発明の属する技術分野】
本発明は薬剤・肥料等の散布剤を圃場等に散布する散布機の散布剤タンク取付装置に関する。
【０００２】
【従来の技術】
従来、上部に散布剤受入口をもつ送風装置と、この送風装置の上方に装着する散布剤タンクとを備えた散布機において、散布剤タンクは、散布作業後、タンク内に残留する散布剤を外部に出し易くしたり、あるいは、タンク下方の送風通路内を清掃し易くするため、送風装置に対し着脱可能に取付られている。このタンクの取付は、例えば、図７に示すように、送風装置Ａにおける散布剤受入口Ｂを挾んで対向する二つの位置に枢支横軸Ｃ，Ｃを介して枢着されるロックレバーＤ，Ｄと、掛止部ｅをもち、前記ロックレバーＤ，Ｄに枢着されるフック体Ｅ，Ｅとをそれぞれ設けると共に、散布剤タンクＦの下部周面に、前記各フック体Ｅ，Ｅの掛止部ｅ，ｅと係合する係合突起Ｇ，Ｇを設けて、散布剤タンクＦを送風装置の散布剤受入口Ｂに載置した状態で、両側のフック体Ｅ，Ｅの掛止部ｅ，ｅを散布剤タンクＦの係合突起Ｇ，Ｇに係合させた後、両側のロックレバーＤ，Ｄを下方側に倒伏させることにより、散布剤タンクＦを送風装置に固定するように構成されている。
【０００３】
【発明が解決しようとする課題】
ところが、この従来のものは、散布剤タンクＦを取付けるとき、タンクＦを散布剤受入口Ｂ周りに載置した後、両方の手でフック体Ｅ，Ｅ及びロックレバーＤ，Ｄを操作する必要があるが、一般に、散布剤タンクＦは、内部の散布剤が前記散布剤受入口Ｂに移行し易いように、下端に向かって絞り込まれた略漏斗状に形成されていて、前記散布剤受入口周りに載せたときに不安定である上、散布剤を満杯近くまで収容すると更に不安定となり易いため、散布剤タンクＦを前記受入口Ｂ周りに単に載せた状態で前記両側のフック体Ｅ，Ｅ及びロックレバーＤ，Ｄを操作するとき、散布剤タンクＦが不用意に傾倒し易くて、フック体Ｅ，Ｅ及びロックレバーＤ，ＤによるタンクＦの取付けが行い難い問題があり、しかも、散布剤受入口Ｂの両側にフック体Ｅ，ＥとロックレバーＤ，Ｄとを装備しているため、部品点数が多くて、構造複雑となり、組付け作業性も悪く、コスト高となる問題があった。
【０００４】
本発明は、一つの係合体を備えた簡単な構造で、しかも、散布剤タンクを不用意に傾倒させることなく容易に取付けることができる散布剤タンク取付装置を提供することを主たる目的とする。
【０００５】
【課題を解決するための手段】
本発明は、上記目的を達成するために、請求項１記載の発明は、図１に示すように、上部に散布剤受入口を有する送風装置と、散布剤が収容される収容部及び該収容部の底部に前記散布剤を調量して前記散布剤受入口に供給する調量弁を有し、前記送風装置の上方に装着する散布剤タンクとを備えた散布機において、前記送風装置の上部一側と前記散布剤タンクの下部一側とに、嵌め込みにより係合して前記散布剤タンクが前記係合箇所を支点として上下方向へ回動可能となるように互いに連結する連結部を有しており、前記送風装置の上部他側に枢支され、これの枢支部を支点とする揺動軌跡に沿って上下方向に傾斜する第１係合部を有し、前記散布剤タンクの下方への回動により前記散布剤タンクの下部他側に当接し、前記散布剤タンクの回動軌跡から外方へ後退動作して前記散布剤タンクの下部他側に係合可能としたレバー体を備えており、前記散布剤タンクの下部他側は前記係合部と等しく傾斜する第２係合部を有することを特徴とする。
【０００８】
【発明の作用効果】
請求項１記載の発明では、散布剤タンクの全体を斜めにした状態でその下部一側の連結部を送風装置の連結部に嵌め込み、この嵌め込み部（連結部）を支点として散布剤タンクを下方に押圧回動させることにより、レバー体を動作させて該レバー体により散布剤タンクの下部他側を送風装置の上部他側に連結することができる。従って、散布剤タンクが従来と同様に形成されたとしても、この散布剤タンクから手を外すことなく、簡易に、確固に取付けることができるのであり、また、レバー体を殊更操作することなく、散布剤タンクをワンタッチで取付けることができる。また、一つのレバー体を設けるだけでよいから、取付構造も簡単にでき、コストを低減できる。
しかも、作業者が散布機を背負ったりしての散布作業時、散布機全体が傾いたり、あるいは散布剤タンクに上下の振動が生じたりして、散布剤タンク側からレバー体に力が作用したとしても、このレバー体の動作を防止できる。従って、散布作業中に、不用意にレバー体が動作して散布剤タンクの取付けが解除されるのを防止できる。

【００１７】
実施形態の係合体６には、前記第１係合部６１の反対側表面に、前記連結部３２，４４を支点とする散布剤タンク４の下方への回動押圧力により係合体６を前記タンク４の回動軌跡に対し外方に後退動作させる当接部６２を設けると共に、前記弁箱４Ｂにおける第２係合部４５の下面に、散布剤タンク４の連結部３２，４４を支点とする回動押圧時、前記当接部６２に当接する傾斜状の押圧部４６を設けて、図６のように散布剤タンク４を下方に回動押圧させるだけで係合体６を後退動作させるようにしている。尚、前記当接部６２を傾斜状に形成する代りに、前記押圧部４６を傾斜状に形成してもよいのであり、散布剤タンク４と係合体６との少なくとも一方に、前記回動押圧力で係合体６を後退動作させる退避手段があればよい。
【００１８】
また、係合体６をその第１係合部６１が第２係合部４５と常時係合する方向に付勢する付勢ばね６３を設けると共に、送風装置３に、係合体６の前記付勢ばね６３による回動範囲を規制して前記押圧部４６と当接部６２とが互いに当接するための揺動規制部３３を設けている。
【００１９】
実施形態における送風装置３は、前記エンジン２により駆動されるファン３Ａと、該ファン３Ａを内蔵したファンケース３Ｂとから成り、このファンケース３Ｂ内に、ファン３Ａの回りに沿って延びる送風通路３４と、この送風通路３４の出口近くから前記散布剤受入口３１に連通する散布剤供給路３５とを備え、送風通路３４の出口にエルボ管７を介して噴管を着脱可能に接続するようにしている。
【００２０】
また、ファンケース３Ｂの下部一側に、横軸から成る枢支部１０を中心として上下方向に揺動可能な調量レバー９と、該調量レバー９を案内するレバーガイド１１とを装着し、調量レバー９の操作部９ａと反対側端部と前記弁軸５１の端部とを、連動部材１２で連結し、調量レバー９の上下方向の揺動操作で前記調量弁５を開閉動作させるようにしている。
【００２１】
また、前記エルボ管７内には、曲率半径の小さい内側通路７ａと、曲率半径の大きい外側通路７ｂとに区画する仕切壁７１を設けて、前記散布剤供給路３５の出口を、内側通路７ａの入口側で且つ仕切壁７１の内側通路面に向けて開口させている。
【００２２】
さらに、ファンケース３Ｂは、エンジン２側と背負枠１側とに分割されて、その外周部が複数の締付ねじ１３で互いに連結されていると共に、この締付ねじ１３の幾つかを利用して防振ゴム１４を着脱可能に取付け、この防振ゴム１４を介して前記背負枠１と着脱可能に連結されている。
【００２３】
防振ゴム１４は、一端にねじ軸１４ａを突設し、他端に挿通孔１４ｂをもつ板状の連結片１４ｃを突設して、前記挿通孔１４ｂに、連結片１４ｃの肉厚よりも長い筒体１５を嵌合し、この筒体１５内に、前記締付ねじ１３を挿通している。
【００２４】
尚、以上の実施形態の係合体６は、枢支部６ａを支点として揺動可能なレバー体で構成されているが、その他、横方向にスライド可能なスライド体で構成してもよい。この実施形態においても、散布剤タンク４とスライド体との少なくとも一方に、前記退避手段と同様の退避手段を設けて、連結部３２，４４を支点とする散布剤タンク４の下方への回動押圧力によりスライド体を前記タンク４の回動軌跡に対し外方に後退動作させるようにしてもよい。
【００２５】
また、以上の実施形態では、散布剤タンク４と係合体６との少なくとも一方に退避手段を設けたが、その他、この退避手段をなくして、連結部３２，４４を支点として散布剤タンク４を回動させるとき、作業者が係合体６を操作し、係合部６１，４５を係脱させるようにしてもよい。この実施形態においても、一方の手で散布剤タンク４を支え、他方の手で係合体６を操作できるから、散布剤タンク４を簡易に、かつ確固に取付けることができるのである。
【００２６】
さらに以上の実施形態では、送風装置３におけるファンケース３Ｂの散布剤受入口３１周りに環状のシール受座３６を設けて、該シール受座３６に、弁箱４Ｂの下端に接触する環状のシール体１６を保持すると共に、ファンケース３Ｂのシール受座３６周りに、弁箱４Ｂを受止めて前記シール体１６が過剰に挾圧されるのを防ぐ受止部３７を設けている。
