【産業上の利用分野】
この発明は、穀粒袋等をフォークで掬い取るとともに所定高さにリフトし、更に、所定位置に運搬可能なリフト付運搬車に関するものである。
【0002】
【従来の技術】
従来、穀粒袋を所定高さに持上げるリフターとしては、実開平6−35297号公報に記載のもの等がある。これらの技術は作業場所移動用のキャスターを備えているが、作業は定位置で固定した状態で、且、穀粒袋を人手により昇降台上に搭載して昇降させるものであり、機体のコンパクトさよりも耐久性を重視した設計となっており、又、穀粒袋をリフトした状態で運搬する機能を有していない。
又、運搬可能な技術としては、特開昭61−169499号公報に記載のもの等、所謂リフトトラック等があるが、これらの技術は重量物を持運ぶ為に開発されたものであって、大きな強度を有し構成が複雑であるとともに、運搬の為の操作性が低いものである。
【0003】
【発明が解決しようとする課題】
この発明は、上記の如き従来技術の欠点を解消し、コンパクトで操作性の良いリフト付運搬車を提供しようとするものである。
【0004】
【課題を解決するための手段】
前開きUの字状の機体フレーム1前後に左右一対の前輪3,3と走行輪2,2とを備え、該機体フレーム1後部中央にはリフトフレーム4を立設しその後部に操縦ハンドル7を設けるとともに、前面にフォーク6を備える昇降体5をリフトフレーム4に沿って昇降自在に構成するに、リフトフレーム4を間隔28をおいて前後に立設する角パイプ枠25と前開きのコの字枠26と上部の連結杆29とから構成し、前側の角パイプ枠25に沿って案内される昇降体5を上下のスプロケット35,36に巻回され一方をコの字枠26内に他方を間隔28内に位置させるチェン27によって昇降可能に構成してなるリフト付運搬車の構成とする。
【0005】
【発明の作用及び効果】
この発明は前述の如く構成するものであるから、機体フレーム1の前後輪2,3を転動して前進させ、前部に設けるフォーク6により穀粒袋等を掬い取るとともに、リフトフレーム4に沿って昇降体5を上昇させフォーク6上の穀粒袋を所定高さにリフトすることができ、又、リフトフレーム4後部に取着の操縦ハンドル7を操作して所定位置に運搬することができる。
又、機体フレーム1後部中央に立設するリフトフレーム4は、間隔28をおいて前後に立設する角パイプ枠25と前開きのコの字枠26と上部の連結枠29とから構成し、前側の角パイプ枠25に沿って案内される昇降体5を上下のスプロケット35,36に巻回され一方をコの字枠26内に他方を間隔28内に位置させるチェン27によって昇降可能に構成するものであるから、機体フレーム1の後部中央に立設するリフトフレーム1を前後の角パイプ枠25とコの字枠26とで側面視門形状に枠組し、その前側に昇降体5を位置させることによって強度を十分に保つとともに、昇降体5の駆動チェン27の一方側を後方の前開きコの字枠26内に他方を間隔28に位置させ空間を有効に利用し、機体をコンパクトに構成できるものである。
【0006】
【実施の態様】
本発明の実施の態様を、縦型穀粒選別計量機における計量袋詰後の穀粒袋の運搬作業を一例として説明する。
縦型穀粒選別計量機Bは、従来公知のものであって、籾摺後の玄米をホッパー16から供給し、内部の揚穀ラセンにより揚穀しながら周囲の選別網から屑粒を漏下させ整粒のみを上方のタンク17へ揚穀供給し、計量台9上の穀粒袋12に充填供給するものである。又、充填量が所定重量になるとシャッター18を閉じて、揚穀される整粒をタンク17内に貯留しその間に穀粒袋12を計量台9から取出す作業システムとなっている。19は左右一対のキャスター輪、20は水平出し用のアジャスターボルトである。計量台9上には、上方に突出する袋支持用の平面状凸部11を中央と左右に、又、フォーク6を挿入可能の凹部13を中央の凸部11の左右に有する袋受台10を載置してある。21は水平出し用のアジャスターボルトであり、底面四隅に設けてある。
【0007】
次に、運搬車Aの構成を説明すると、平面視前開きUの字状の機体フレーム1は、後部フレーム1aと、計量台9よりも広い間隔の左右の側部フレーム1b,1bとを丸パイプ材を屈曲させて一体に構成してある。又、後部フレーム1aから若干の間隔を置く左右の側部フレーム1b,1bから取付ブラケット22,22を溶着垂下し、該ブラケット22,22間にホイルパイプ23を溶着して機体フレーム1を枠組補強するとともに、該ホイルパイプ23に左右の走行輪2,2を回転自在に軸支させてある。
側部フレーム1b,1bの先端は下方に屈曲し、夫々の下端に前輪3,3を軸支してある。又、該前輪3,3は、走行輪2,2よりも外側に位置させてあり、従って該前輪3,3が機体の最外側に位置し、運転操作が容易である。
【0008】
24,24は連結プレートであり、後部フレーム1aとホイルパイプ23間を枠組構成するとともに、該左右の連結プレート24,24間にリフトフレーム4下部を溶着して立設してある。該リフトフレーム4は、前部の角パイプ枠25と、間隔28を置いてその後部に位置する前開きのコの字枠26を上記連結プレート24,24にその下部を溶着して立設するとともに、その上端間を連結枠29で連結してある。該連結枠29の上部背面は斜めのカット面57とし、後述の袋口の紐結び作業を機体後方から行うに際し支障とならないよう構成してある。
30はモータ、31は減速ギヤボックスであり両者は一体的に連結されるとともに、後部フレーム1aとホイルパイプ23間の連結プレート32にギヤボックス31が取着される。モータ30の出力はギヤボックス31内のウォームホイル減速機構により減速されるとともに、その出力軸33は、連結プレート24,32間に溶着するパイプ34内を貫通してその端部を連結プレート24,24間に位置させるとともに、駆動スプロケット35を軸着してある。又、リフトフレーム4上部の連結枠29は上蓋状に構成するとともに、従動スプロケット36を軸架してある。
【0009】
昇降体5は、角パイプ枠25に沿って昇降するものであり、該角パイプ25を囲う昇降枠37の前側上下の2ヶ所と後側上部に、つば付ロール38,38を回転自在に軸架し、該角パイプ枠25の前、後面に沿って転動案内され昇降可能に構成してある。駆動スプロケット35と従動スプロケット36間にはチェン27を巻回し、チェン27の一端は、昇降枠37の後部連結枠39に上方から連結し、該チェン27の他端は昇降枠37の下部に連結される。その具体構成を説明すると、昇降枠37下部に取着のコの字状取付枠40に下方から摺動杆41を挿通するとともにスプリング42を介装して該摺動杆41を上方に向け弾発するとともに、該摺動杆41下端にチェン27を連結してあり、該スプリング42の弾発力により、昇降駆動時のショックを吸収可能に構成してある。又、上下のスプロケット35,36間に巻回されるチェン27は一方側をコの字枠26内に、他方側を間隔28に位置させて上述の如く昇降枠37に連結してある。
【0010】
昇降枠37の前面には、フォーク6の基部を上方に屈曲させて取着してある。該フォーク6は、杆材により先端をUの字に折曲する狭幅の左右の支持杆43,43により構成するとともに、昇降枠37の両側部に左右一対設けてある。又、該フォーク6,6の前方への突出長さは、側部フレーム1bの先端が前述の計量台9の略中心位置に延出されるに対し、計量台9上に載置する袋受台10の全長に相当する長さに設定し、袋受台10の凹部13に挿入して穀粒袋12を下方から取込み可能に構成してある。56はカバーであり、フォーク6の取付部を覆ってある。
44は袋受杆であり、昇降枠37上部両端から前方上方に屈曲延出するとともに、その受部を穀粒袋12の形状に沿う湾曲状に形成してある。
【0011】
コの字枠26一側には、昇降体5の上昇、下降端位置を検出してモータ30の駆動を断続する上限リミットスイッチ45と下限リミットスイッチ46と、穀粒袋12の袋口を閉めるに適した袋結び位置を検出してモータ30の駆動を断つ中間リミットスイッチ47を設けてある。48は昇降枠37後部から突出するリミットスイッチ作動用のカム板である。なお、これら各リミットスイッチ45,46,47は、作業条件に対応してその上下取付高さ位置を変更可能に構成してある。又、49,49はカバーであり、箱状に形成され、角パイプ枠25,チェン28の移動空間をなす間隔28,及びコの字枠26の左右両外側を覆ってある。50は起動スイッチであり、モータ30を起動し、各リミットスイッチ45,46,47の検出時まで駆動を継続するものである。又、昇降体5の下降は、上限リミットスイッチ45の検出後、タイマー設定により一定時間後に開始される。なお、タイマーに換えて起動スイッチ50により昇降体5を下降させてもよい。
又、51は電源用のバッテリーであり、中央のリフトフレーム4を挾み、モータ30及びギヤボックス31の左右他側に配置され、機体の左右のバランスを保持する。又、これらの重量物であるバッテリー51,モータ30,ギヤボックス31は、走行輪2,2を軸支するホイルパイプ23上の低い位置に配設し、機体の傾動時にも前後バランスを保持すべく構成してある。52は制御用のコントロールボックスであり、モータ30上の取付枠53に搭載する。
なお、図12に記載する符号58は足踏スイッチを示し、ハンドル8,8を押し下げて機体を後傾させる際に、機体フレーム1後部を足で踏みその操作を助成するとともに、足踏スイッチ58をを操作し、モータ30を駆動して昇降体5を上昇させるものであり、起動スイッチ50と併設しても、又、単独で設けてもよい。
【0012】
左右一対の操縦用ハンドル7,7は、パイプ杆を屈曲して一体に形成するとともに、その中央を止具53によりリフトフレーム4の上部背面に止着してある。該操縦ハンドル7,7は、機体と同幅の広幅で後方に拡開して操縦操作を容易に構成するとともに、前、後輪2,3を接地させる機体の据置時後方上方に傾斜して延設してあり、走行輪2,2を中心として機体を後傾させ前輪3,3を浮かせての運搬時に該操縦ハンドル7,7が略水平となるよう構成してある。
操縦ハンドル7,7の基部近傍下面には、取込み用ハンドル8,8を溶着してあり、該取込み用ハンドル8,8は、取付部から後方に向け水平状に、且つ、左右平行して延設してある。従って、該取込みハンドル8,8は、操縦ハンドル7,7より狭幅で、且つ、機体据置時水平状に後方に突出し、作業者が体重を掛けて該ハンドル8,8を容易に押下げ可能に構成してある。
【0013】
前輪3,3は鋳造品であり、又、左右の側部フレーム1b,1b下部には略該側部フレーム1b,1b幅と同じく鋳造製の厚板からなるウエイト54,54を取着してある。これらの鋳造品からなる前輪3,3とウエイト54,54は、昇降体5の上昇により作業者が取出し易い位置に持上げられる穀粒袋12を取出した際、その反動による機体の後方への転倒を防止するものである。
ストッパー14,14は図7乃至図9に示す如く、計量台9の前後中心部に設けられ、前進する運搬車Aの前輪3,3を所定位置、即ち、穀粒袋12の取込みに適した位置に停止させるものであり、又、運搬車Aの計量台9への衝突を防止できる。該ストッパー14,14は、縦型穀粒選別計量機Bの左右のアジャスターボルト20,20にその基部を共締めされる細幅の取付板55,55先端に、前輪3,3と直交して溶着される丸棒で構成してある。
ストッパー14とアジャストボルト20とは共締にしているため、ストッパー14と計量台9上の穀粒袋12の位置関係が一定であり、フォーク6により確実に取込むことができる。
なお、該ストッパー14,14は、計量台9等他の部材に取付けてもよい。
【0014】
又、図10,図11に示すものは、ストッパー14,14とともに、取付板55,55先端に平板を屈曲形成する円弧状の案内体15,15を設けたものであり、該案内体15,15は、穀粒袋12の取込み時に、前輪3,3の上昇高さを規制案内するものであり、運搬車Aの過度の後傾を規制し、フォーク6上の穀粒袋12が縦型穀粒計量選別機Bのシャッター18等へ接当することを防止する。なお、該案内板15に、ストッパー14の機能を兼用させてもよい。
【0015】
例えば穀粒選別計量機で計量袋詰する穀粒袋12の運搬作業を行う場合には、計量を行う計量台9上に上方に突出する袋支持用の凸部11とフォーク6を挿入可能の凹部13を備える袋受台10を置いて計量袋詰作業を行い、次に運搬車Aのフォーク6を袋受台10の凹部13に挿入するとともに、フォーク6を若干浮かせて該フォーク6上に穀粒袋12を取込む。
この取込みに際しては、前開きUの字状の機体フレーム1後部に軸架する左右一対の走行輪2,2の転動により運搬車Aを前進させ、機体フレーム1後部に立設するリフトフレーム4に沿って昇降自在の昇降体5前面に設けるフォーク6を、前述の袋受台10の凹部13に挿入する。次に、フォーク6を浮かせて穀粒袋12をフォーク6上に取込むのであるが、穀粒袋12は通常30kg、地域によっては60kgの重量があり、昇降体5の重量等も加わり取込み作業には大きな操作力を必要とする。
【0016】
取込み開始時、即ちUの字状の機体フレーム1左右先端の前輪3,3が接地する据置時において、略水平状態の取込み用ハンドル8,8を作業者が自然な姿勢で体重を掛けて押下げることにより機体フレーム1を走行輪2,2軸を中心に回動させ、フォーク6上に重量物である穀粒袋12を取込むとともに前輪3,3を接地面から上昇させることができる。この状態で運搬車Aを後方へ引き計量台9から引離すとともに、穀粒袋12の袋口を閉じる作業を行う。
次に、運搬作業を行う際には、操縦用ハンドル7,7を押下げて機体フレーム1を走行軸2,2軸を中心に回動させ機体前部を浮かせると、機体がフォーク6上に搭載する穀粒袋12とともに後傾状態となり、機体全体の重心位置が走行輪2,2の略上方の前後バランスを保つ位置に移動する。この機体の後傾に伴って、上方の操縦ハンドル7,7が操作に適する水平位置に移動する為、作業者は取込み用ハンドル8,8から操縦ハンドル7,7に持ち換えることによって重量物の運搬を容易に行うことができる。
この運搬途中において、又は、所定位置への運搬後に、昇降体5を上昇させることにより、その前面に設けるフォーク6上の穀粒袋12を所定高さに上昇させ、重量物である穀粒袋12を作業者の腰の高さ、又は、肩の高さに位置させ腰を屈める必要なくフォーク6上から取出すことができる。
又、機体フレーム1後部中央に立設するリフトフレーム4は、間隔28をおいて前後に立設する角パイプ枠25と前開きのコの字枠26と上部の連結枠29とから構成され、前側の角パイプ枠25に沿って案内される昇降体5を上下のスプロケット35,36に巻回され、一方をコの字枠26内に他方を間隔28内に位置させるチェン27によって昇降可能に構成するものであり、前後の角パイプ枠25とコの字枠26とで側面視門形状に枠組され、その前側に昇降体5を位置させることによって強度を十分に保つとともに、昇降体5の駆動チェン27の一方側を後方の前開きコの字枠26内に他方を間隔28に位置させ空間を有効に利用し機体をコンパクトに構成してある。
更に、チェン27は、その前後を角パイプ枠25とコの字枠26によってカバーされ部材を少なくできるとともに安全である。
