【０００２】
【従来の技術及び発明が解決しようとする課題】
使用済の育苗箱を洗浄する作業は角隅部や凹部などに汚れが付着し、しかもこの汚れが乾燥しているため手間のかかる厄介な作業であった。
【０００３】
また、農業の生産性の向上や農業構造の改善，近代化を計るため、近年専業農家を中心として大規模農業の経営が促進されつつあるが、その場合大量な数に達する育苗箱の洗浄作業が大きな関心事となってきている。
【０００４】
本発明は上記問題を解決するため、導入移送ローラで機体内に導入した使用済の育苗箱を移送しながら噴射ノズルによりジェット洗浄したあと、回転するブラシ体で洗浄し導出移送ローラで機外に導出することにより育苗箱を自動的に洗浄できる育苗箱洗浄機を提供することを技術的課題とするものである。
【０００５】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００６】
機体１の左端部に所定の間隙を置いて対設した上下一組の導入移送ローラ２・２’と機体１の右端部に所定の間隙を置いて上下一組の導出移送ローラ３・３’を設け、この左右の導入・導出移送ローラ２・２’，３・３’の間に上下の噴射ノズル４により育苗箱ｗをジェット洗浄する洗浄機構５とジェット洗浄された育苗箱ｗを回転しながらブラシ洗浄する上下に対設したブラシ体６・６’とを設け、前記洗浄機構５を機体１内の所定の位置に着脱自在に係止できる角形形状のジェット洗浄枠体 12 で形成し、このジェット洗浄枠体 12 を構成する上下の洗浄パイプ 13 に育苗箱ｗをジェット洗浄する複数個の噴射ノズル４を付設し、このジェット洗浄枠体 12 に高圧ポンプ 14 を連設したことを特徴とする育苗箱洗浄機に係るものである。
【０００７】
また、前記ブラシ体６・６’を左右の分割ブラシ体６ _１・６ _２，６ _１ ’・６ _２ ’に形成し、この夫々のブラシ体６・６’のいずれか一方のブラシ体６の前後のフランジ部に分割ブラシ体６ _１・６ _２の回転中の振れを防止する係止手段 15 を設け、この夫々のブラシ体６・６’を上下のブラシ軸 16 ・ 16 ’に着脱可能に固定する取付ボルト 17 を付設したことを特徴する請求項１記載の育苗箱洗浄機に係るものである。
【０００８】
また、機体１の左端部に所定の間隙を置いて対設した上下一組の導入移送ローラ２・２’と機体１の右端部に所定の間隙を置いて上下一組の導出移送ローラ３・３’を設け、この左右の導入・導出移送ローラ２・２’，３・３’の間に上下の噴射ノズル４により育苗箱ｗをジェット洗浄する洗浄機構５とジェット洗浄された育苗箱ｗを回転しながらブラシ洗浄する上下に対設したブラシ体６・６’とを設け、前記ブラシ体６・６’を左右の分割ブラシ体６ _１・６ _２，６ _１ ’・６ _２ ’に形成し、この夫々のブラシ体６・６’のいずれか一方のブラシ体６の前後のフランジ部に分割ブラシ体６ _１・６ _２の回転中の振れを防止する係止手段 15 を設け、この夫々のブラシ体６・６’を上下のブラシ軸 16 ・ 16 ’に着脱可能に固定する取付ボルト 17 を付設したことを特徴する育苗箱洗浄機に係るものである。
【０００９】
【発明の実施の形態】
本発明の実施の形態を作用効果を示して実施の一例である図面に基づいて説明する。
【００１０】
本発明は、機体１の左端部に所定の間隙を置いて対設した上下一組の導入移送ローラ２・２’間に使用済の育苗箱ｗを挿入すると、導入移送ローラ２・２’により育苗箱ｗが機体１内に導入移送され、洗浄機構５の上下の噴射ノズル４よりのジェット噴出水により育苗箱ｗがジェット洗浄され、次いで上下に対設した回転するブラシ体６・６’によりブラシ洗浄されながら導出移送ローラ３・３’側に移送され導出移送ローラ３・３’により機外に導出される。
【００１１】
このように使用済の育苗箱ｗが導入移送ローラ２・２’，上下の回転するブラシ体６・６’により機体１内に移送されながらジェット洗浄・ブラシ洗浄の二段階洗浄方式で洗浄され、導出移送ローラ３・３’により機外に導出されるため育苗箱ｗが能率良く洗浄できる。
【００１２】
また、本発明は、角形形状のジェット洗浄枠体12を機体１内の左右の導入・導出移送ローラ２・２’，３・３’の間の所定の位置に着脱自在に係止できるよう設けたので、例えば、噴射ノズル４が詰まったりしたとき、このジェット洗浄枠体12を簡単に機外に取り出して噴射ノズル４を清掃したり新品と取り替えたりしたあと、このジェット洗浄枠体12を簡単にもとの設置位置に復元できる。
【００１３】
高圧ポンプ14を稼働すると高圧水がジェット洗浄枠体12を構成する上下の洗浄パイプ13の噴射ノズル４より噴射して育苗箱ｗに付着している土や苗くずなどの汚れを箱の隅々までジェット洗浄する。
【００１４】
また、ブラシ体６・６’を左右の分割ブラシ体６_１・６_２，６_１’・６_２’に形成し、この夫々のブラシ体６・６’のいずれか一方のブラシ体６の前後のフランジ部に分割ブラシ体６_１・６_２の回転中の振れを防止する係止手段15を設け、この夫々のブラシ体６・６’を上下のブラシ軸16・16’に着脱可能に固定する取付ボルト17を付設した場合には、使用中にブラシ体６の刷毛などが摩耗したり損傷したりしたときは、夫々のブラシ体６・６’の取付ボルト17を上下のブラシ軸16・16’より取り外しブラシ体６の係止手段15を解除するとブラシ軸16・16’が機体１にセットされたままの状態でブラシ体６・６’がブラシ軸16・16’よりそっくり取り外される。
【００１５】
新しい分割型のブラシ体６・６’をブラシ軸16・16’に前記取付ボルト17により固定し、ブラシ体６のフランジ部を係止手段15で係止して再び育苗箱洗浄作業を継続する。
【００１６】
ブラシ体６・６’が回転しながら育苗箱ｗをブラシ洗浄するとき、このブラシ体６の前後のフランジ部に設けた係止手段15により左右の分割ブラシ体６_１・６_２が一体となっているため回転中の相互の振れが防止でき、従来のこの種の分割ブラシ体のように回転中の相互の振れの発生がなくスムーズにブラシ洗浄できる。

【００２４】
洗浄機構５について説明する。
【００２５】
左右の導入・導出移送ローラ２・２’,３・３’の間の所定の位置の機体本体１_１の前後の側板１_４にチャンネル形状のホルダー受け28を溶接にて対設し、この前後のホルダー受け28の前後のフランジ部28_１にガイド嵌入するホルダー板12_１を設け、このホルダー板12_１の上端部を鍵型形状に折り曲げてこの突設鍵部12_２を前記ホルダー受28のウェブ部28_２に当設するように設け、前後に対設したホルダー板12_１の上・下部寄りに洗浄パイプ13・13を架け渡し、上下の洗浄パイプ13・13の前後の上下端部寄りを導水パイプ13’・13’で連通し、前記上下の洗浄パイプ13・13に複数個の噴射ノズル４を対向状態に付設し、上部の洗浄パイプ13のほぼ中央部にカップリング29を設けて角形形状のジェット洗浄枠体12を形成する。
【００２６】
このジェット洗浄枠体12を前後の側板１_４に設けたホルダー受28・28にジェット洗浄枠体12のホルダー板12_１をホルダー受28のフランジ部28_１をガイドとして嵌入し、ホルダー板12_１の突設鍵部12_２’をホルダー受け28のウェブ部28_２の上端縁に当接せしめてジェット洗浄枠体12を機体１の所定の位置に着脱可能に係止する。架台１_２内に高圧ポンプ14を設けてこの高圧ポンプ14の吐出部と前記カップリング29間を急速接続金具30を介して高圧ホース31で連結して洗浄機構５を構成する。

【００２８】
次に、ブラシ体６・６’について説明する。
【００２９】
機体本体１_１の前記洗浄機構５と導出移送ローラ３・３との間の前後の側板１_４の外壁に上下対向状態に封水型シールを付設した軸受を止着し、この軸受に上下のブラシ軸16・16’を回転自在に架設し、このブラシ軸16・16’に夫々左右に分割した前後縦二つ割り形状のブラシ筒体を被嵌し、このブラシ筒体の例えば上部のブラシ筒体の前後に夫々半割り形状のフランジ部を設けて上部のブラシ体６を形成し、このブラシ体６の筒部とフランジ部に図の３のように夫々育苗箱ｗをブラシ洗浄する刷毛体32を千鳥ピッチ形状に植設して分割ブラシ体６_１・６_２を構成し、下部のブラシ筒体６’のブラシ筒体に育苗箱ｗを洗浄する刷毛体32を千鳥ピッチ形状に植設し、この分割した上部のブラシ体６の半体のフランジ部端面に分割ブラシ体６_１・６_２の回転中の振れを防止する係止手段15を設ける。

【００３２】
次に無端駆動チェーン11による駆動機構36について説明する。
【００３３】
前記下部の導入ローラ軸22’及び下部の導出ローラ23’の前端部を前方の側板１_４より突設状態に延設してこの延設部に同形のスプロケット７を止着し、前方の側板１_４に前記左右の枢着部24を軸とし擺動腕杆25の擺動半径を半径として円弧状の溝孔を対向状態に穿溝し、上部の導入ローラ軸22及び上部の導出ローラ軸23の前端部を前記円弧形形状の溝孔を経由して突設状態に延設し、この延設部に前記と同形のスプロケット７を止着し、架台１_２に設けたモータ10の出力軸を図１のように時計廻りに回転するように設けてこの出力軸に駆動スプロケット37を止着し、下方のブラシ体６’のブラシ軸16’の前端部を前方の側板１_４より突設状態に延設してこの延設部にブラシ体用スプロケット38と下部導出ローラ３’を駆動する導出ローラ駆動スプロケット39を止着し、下部導出ローラ軸23’の延設部に従動スプロケット８を止着して前記駆動スプロケット37・ブラシ体用スプロケット38間にモータ用無端駆動チェーン40と導出ローラ駆動スプロケット39・従動スプロケット８間に下部導出ローラ用無端駆動チェーン41を掛け渡し、前方の側板１_４の左右上端部寄りにアイドル軸42を突設してこの夫々のアイドル軸42にアイドルスプロケット９を回転自在に軸着する。
【００３４】
前方の側板１_４の外壁の中央下端部付辺に枢着部43を設け、この枢着部43に止着した枢着軸に二枚構成の擺動アーム44の基部を軸着し、二枚構成の擺動アーム44の他端部にアイドルスプロケットシャフト45を架設し、このアイドルスプロケットシャフト45の中央にアイドルスプロケット９を回転自在に軸着し、擺動アーム44と側板１_４との間にテンションバネ44’を架設してこのアイドルスプロケット９を常時下方に付勢するように設けて後述の無端駆動チェーン11の駆動中の張力を調節しながら変位を吸収できるように構成する。
【００３５】
無端駆動チェーン11の掛け渡し方法について説明する。
【００３６】
下部の導出ローラ軸23’のスプロケット７・中央下端部寄りのアイドルスプロケット９・下部導入ローラ軸22’のスプロケット７・上部導入ローラ軸22のスプロケット７・左上端部寄りのアイドルスプロケット９・右上端部寄りのアイドルスプロケット９・上部導出ローラ軸22のスプロケット７を経由して下部の導出ローラ軸22’のスプロケット７に無端駆動チェーン11を掛け渡し、この無端駆動チェーン11を上部導入ローラ軸22のスプロケット７，上部導出ローラ軸23のスプロケット７にのみチェーンが背面掛けになるように設けて無端駆動チェーン11による駆動機構36を構成する。
【００３７】
本発明の駆動機構36を上記のように構成したので、モータ10の出力軸が図１のように時計回りに回転するとモータ用無端駆動チェーン40によりブラシ体用スプロケット38・導出ローラ駆動スプロケット39を介して下部導出ローラ用無端駆動チェーン41により従動スプロケット８が時計回りに回転するので下部導出ローラ軸23’及びこの下部導出ローラ軸23’に止着したスプロケット７が時計回りに回転し、無端駆動チェーン11により中央下端部寄りのアイドルスプロケット９・下部導入ローラ軸22’のスプロケット７を介して下方の導入移送ローラ２’を時計回りに、上部導入ローラ軸22のスプロケット７を介して上方の導入移送ローラ２を反時計方向に回転せしめるので導入窓20より導入された育苗箱ｗが機体１内に導入される。更に無端駆動チェーン11が左・右上端部寄りのスプロケット９・９を経由して上部導出ローラ軸23のスプロケット７を反時計回りに下部導出ローラ軸23’のスプロケット７を時計回りに回転せしめるので上の導出ローラ３・下の導出ローラ３’が互いに反対方向に回転して機内に導入された育苗箱ｗを導出窓21より機外へ導出する。
【００３８】
また、下方のブラシ体６’がブラシ体用スプロケット38の時計回りの回転により育苗箱ｗを導出側へ移送するよう回転するので、前記一組の導入移送ローラ２・２’により機内に導入された育苗箱ｗの下面をこの下方のブラシ体６’で導出側へ移送せしめるとともにこの下方のブラシ体６’に対設した上方のブラシ体６が育苗箱ｗの移送に伴って反時計方向に回転し、ジェット洗浄された育苗箱ｗをブラシ体６・６’の刷毛が上下から挟み込むようにブラシ洗浄して導出側に移送するように作動する。
【００３９】
また、上下のブラシ軸16・16’に新たに夫々プーリーを止着し、この上下のプーリーにベルトをクロス掛けに張設したり、一対の歯車を設けて上方のブラシ体６を強制回転せしめて上方のブラシ体６により能動的に育苗箱ｗを洗浄するように設けても良い。
【００４０】
【発明の効果】
本発明を上記のように構成したので、機体の左端部に所定の間隙を置いて対設した上下一組の導入移送ローラと機体の左端部に所定の間隙を置いて上下一組の導出移送ローラを設け、この左右の導入・導出移送ローラの間に上下の噴射ノズルにより育苗箱をジェット洗浄する洗浄機構とジェット洗浄された育苗箱を回転しながらブラシ洗浄する上下に対設したブラシ体とを設けたため、機体の左端部に所定の間隙を置いて対設した上下一組の導入移送ローラ間に使用済の育苗箱を挿入すると、導入移送ローラにより育苗箱が機体内に導入移送され、洗浄機構の上下の噴射ノズルよりのジェット噴出水により育苗箱がジェット洗浄され、次いで上下に対設した回転するブラシ体によりブラシ洗浄されながら導出移送ローラ側に移送され導出移送ローラにより機外に導出される。
【００４１】
このように使用済の育苗箱が導入移送ローラ，上下の回転するブラシ体により機体内に移送されながらジェット洗浄・ブラシ洗浄の二段階洗浄方式で洗浄され、導出移送ローラにより機外に導出されるため育苗箱が能率良く洗浄できる秀れた作業性を有する育苗箱洗浄機となる。
【００４２】
また、本発明では、洗浄機構を機体内の所定の位置に着脱自在に係止できる角形形状のジェット洗浄枠体で形成し、このジェット洗浄枠体を構成する上下の洗浄パイプに育苗箱をジェット洗浄する複数個の噴射ノズルを付設し、このジェット洗浄枠体に高圧ポンプを連設したため、角形形状のジェット洗浄枠体が機体内の左右の導入・導出・移送ローラの間の所定の位置に着脱自在に係止できるので、例えば、噴射ノズルが詰まったりしたとき、このジェット洗浄枠体を簡単に機外に取り出して噴射ノズルを清掃したり新品と取り替えたりすることができるうえに、この門型枠体を簡単にもとの設置位置に復元できる。
【００４３】
また、高圧ポンプを稼働すると高圧水がジェット洗浄枠体を構成する上下の洗浄パイプの噴射ノズルより噴射して育苗箱に付着している土や苗くずなどの汚れを箱の隅々までジェット洗浄するため、育苗箱が急速に洗浄される効率の良い秀れた実用性を発揮する育苗箱洗浄機となる。
【００４４】
また、請求項２記載の発明においては、ブラシ体を左右の分割ブラシ体に形成し、このブラシ体のいずれか一方のブラシ体の前後のフランジ部に分割ブラシ体の回転中の振れを防止する係止手段を設け、この夫々のブラシ体を上下のブラシ軸に着脱可能に固定する取付ボルトを付設したため、使用中にブラシ体の刷毛などが摩耗したり損傷したりしたときは、いずれか一方のブラシ体の係止手段を解除して取付ボルトを上下のブラシ軸より取り外すと、ブラシ軸が機体にセットされたままの状態でブラシ体がブラシ軸よりそっくり取り外される。
【００４５】
新しい分割型のブラシ体をブラシ軸に前記取付ボルトにより固定し、いずれか一方のブラシ体のフランジ部を係止手段で係止して再び育苗箱洗浄作業を継続できるうえに、ブラシ体が回転しながら育苗箱をブラシ洗浄するとき、このブラシ体の前後のフランジ部に設けた係止手段により左右の分割ブラシ体が一体となって回転中の相互の振れが防止でき、従来のこの種の分割ブラシ体のように回転中の相互の振れの発生がなくスムーズに育苗箱がブラシ洗浄できるため、育苗箱の洗浄を極めて効率良く実施できる作業性の良い育苗箱洗浄機となる。
