【発明の属する技術分野】
この発明は牛蹄削蹄装置に於ける牛首遊挿孔の調節装置に関するものであり、特に、牛首遊挿孔に牛首が挿入されたとき、牛首の上下動を規制することによる牛の前後足の躍動を停止させて牛蹄の削蹄作業の安全性が期待できるようにした牛蹄削蹄装置に於ける牛首遊挿孔の調節装置に関するものである。
【０００２】
【従来の技術】
本願出願人は、牛蹄削蹄装置を特願平９−０４０２９０号として先に出願した。而して、この先願に係る装置は、フレームによって箱型に形成される牛収容室であって、該牛収容室は後方に牛の出入部を有し、該出入部の後扉及び前扉並びに側扉が開閉自在に形成されると共に、該牛収容室に入室した牛の吊り上げ装置を備え、更に、左右両側扉下方部の前方部位及び後端部位に夫々牛足固定具を備え、更に、上記前扉は左右の扉から成り、且つ、両扉を合接したとき縦方向中央部が牛首を遊挿できる程度の縦長状の牛首遊挿孔が形成できるように構成され、且つ、該左右の扉は内側部の下端部をフレームに枢支して上方部を左右下方向へ夫々拡開できるように構成されて成るものである。
【０００３】
そこで、この牛蹄削蹄装置で牛の蹄を削蹄しようとする際には、先ず、前後左右の夫々の扉を開放し、前記牛足固定具を夫々横方向へ開いておく。そして、後方の牛の出入部から牛収容室内に牛を入れる。然る後、前記扉を閉じる。このとき、前面の扉は左右の前扉が下部の枢支部を回動支点として中央部に回動し、そして、縦長の牛首遊挿孔が形成され、この牛首遊挿孔に牛首が遊挿されることになる。更に、後部の扉も閉じ、更に、牛の吊り上げ装置によって牛を吊り上げた後、前記牛足固定具に牛の前足及び後足を夫々固定し、作業員によって削蹄作業が行われるのである。
【０００４】
【発明が解決しようとする課題】
上記先願に係る装置に牛を収容して牛蹄を削蹄しようとするとき、牛首は縦長の牛首遊挿孔に遊挿された状態となる。然るときは、該牛首遊挿孔に遊挿された牛は、該牛首を牛首遊挿孔の縦方向に自在に移動させることができる。而して、牛首を縦方向に自在に移動させるとき、牛は習性により牛足も同時に自在に躍動させることが多く、依って、牛足固定具に牛足を固定すること自体が困難であり、且つ、一旦、牛足を牛足固定具に固定した後に於ても、前記牛首の縦方向の任意の移動に伴って牛足固定具に牛の力が負荷され、牛が自らの牛足を傷つけたり、或いは牛足固定具、又はその周辺器物、或いは削蹄する作業員に損傷を及ぼすと云う憂いがある。
【０００５】
そこで、牛蹄削蹄装置に於て牛足の固定を確実、且つ、安全ならしめるために解決せらるべき技術的課題が生じてくるのであり、本発明は該課題を解決することを目的とする。
【０００６】
【課題を解決するための手段】
この発明は上記目的を達成するために提案せられたものであり、フレームによって箱型に形成される牛収容室であって、該牛収容室は後方に牛の出入部を有し、該出入部の後扉及び前扉並びに側扉が開閉自在に形成されると共に、該牛収容室に入室した牛の吊り上げ装置を備え、更に、左右両側扉下方部の前方部位及び後端部位に夫々牛足固定具を備え、更に、上記前扉は左右の扉から成り、且つ、両扉を合接したとき縦方向中央部が牛首を遊挿できる程度の縦長状の牛首遊挿孔が形成できるように構成され、且つ、該左右の扉は内側部の下端部をフレームに枢支して上方部を左右下方向へ夫々拡開できるように構成されて成る牛蹄削蹄装置に於て、前記牛首遊挿孔に牛首が遊挿されたとき、該牛首の上下動を規制すべく該牛首遊挿孔の前面に規制杆を回動自在に架設した牛蹄削蹄装置に於ける牛首遊挿孔の調節装置を提供するものである。
【０００７】
【発明の実施の形態】
以下、本発明の一実施の形態を図１乃至図７に従って詳述する。尚、説明の都合上、先ず本願出願人が先に出願した特願平９−４０２９０号の牛蹄削蹄装置について説明する。
【０００８】
図に於て１は牛蹄削蹄装置である。該牛蹄削蹄装置１はフレーム２によって箱型に形成された牛収容室３を有し、更に、該牛収容室３の前面には中央部から左右個別に設けられた左前扉４と右前扉４ａが設けられている。而して、該左前扉４及び右前扉４ａは牛収容室３の前面中央部に位置する部分の夫々の左扉枠５及び右扉枠５ａの下端部を該牛収容室３の前面下方部のフレーム２ａに枢支され、そして、該枢支部６，６ａを回動支点として夫々上方部が左右へ回動して前扉を開放できるように構成されている。
【０００９】
而して、該前扉の開閉装置としては、図１に於て該牛収容室３の前面上方部のフレーム２ｂの位置から右側へ延設し、該延設部の先端部に作動杆７の略中央部を枢着し、該枢着部８にレバー９を固設して、該レバー９を回動させることにより該作動杆７が該枢着部８を回動支点として回動するように構成されている。そこで、該作動杆７の上端部には前記左前扉４の左扉枠５の上端部に一端部を枢着した左前扉用連杆１０の他端部が枢着されており、更に、該作動杆７の下端部には前記右前扉４ａの右扉枠５ａの上方部に一端部を枢着した右前扉用連杆１０ａの他端部が枢着されている。従って、前記レバー９を矢印Ｘ方向に回動させれば前記左前扉４は下端部の枢支部６を回動基点として左方へ回動して該左前扉４が開放され、そして、右前扉４ａは右方へ回動して該右前扉４ａが開放されることになる。
【００１０】
又、該レバー９を矢印Ｙ方向（実線の位置）に回動させれば左右の前扉５，５ａは図示実線のように閉塞する。而して、この左右前扉４，４ａは図１の実線の位置で閉塞しているのであるが、この閉塞状態に於て左扉枠５及び右扉枠５ａが各別に左方及び右方へ湾曲凹設され、そして、牛収容室３内に牛が収容されたとき、前記左右の扉枠５，５ａによって牛の首が遊挿できて上下移動が可能な縦長の牛首遊挿孔１１が形成される。このように縦長の牛首遊挿孔１１を形成すべく前記左右の前扉４，４ａが閉塞状態にあるとき、この閉塞状態にある左右の前扉４，４ａが不慮開放しないようにするために、先端部に歯部１２ａを有する固定具１２の一端部を前記左扉枠５の上端部近傍に枢着し、そして、前記歯部１２ａを右方向の縦フレーム２ｃに設けた係止部１３に係止できるように構成されている。勿論、該左右の前扉４，４ａを開放しようとする際には該固定具１２を上方へ回動して前記歯部１２ａによる噛合を解除し、そして、前述の操作により該左右の前扉４，４ａを開放させることは当然である。
【００１１】
又、図３に示す如く、該牛収容室３の左右側部にも側扉１４，１４が設けられ、そして、該左右双方の側扉１４，１４は夫々の前端部の側扉枠１４ａ，１４ａの上下端部をフレームに枢支し、この枢支部を回動支点として開放することができるように構成されている。
【００１２】
更に又、図４に示すように、該牛収容室３の後部を牛の出入部１５とし、そして、該牛の出入部１５は一端部を枢支して開閉自在に形成された後扉１６が配設されている。
【００１３】
又、図３に示す如く、前記左右双方の側扉１４，１４の前方下部に開口部１７，１７を設け、該開口部１７，１７部位に牛の前足固定具１８，１８を備えておく。而して、該前足固定具１８は鍵型に折曲されて成り、前端部の下部縦軸１８ａをフレーム２に対して回動自在に枢着されており、そして、該下部縦軸１８ａの上端部から水平方向にアーム１８ｂを延設し、該アーム１８ｂの先端部に上部縦軸１８ｃを上下長さ調整自在に立設されている。詳しくは該上部縦軸１８ｃは外筒に対して中軸を遊挿し、外筒にピン孔を開穿して、該ピン孔にピンを挿入固定して上下高さを調整できるように構成されている。而して、該上部縦軸１８ｃの上端部には半月状に湾曲した牛足載置片１８ｄが固設されており、更に、牛足載置片１８ｄの前端部に半月状に湾曲された牛足固定片１８ｅの前端部を枢支し、牛の前足を牛足載置片１８ｄの上面に載置した後、該牛足固定片１８ｅを回動して該牛足の上面から牛足を押えて該牛足を固定できるように、該牛足載置片１８ｄと牛足固定片１８ｅを合接したときに双方によって卵形空所１９が形成される。
【００１４】
斯くの如く、牛の前足は牛蹄を上方に向いた状態で該卵形空所１９内に固定される。該固定に当っては、別途チェン２０を前記牛足載置片１８ｄと牛足固定片１８ｅの後端部に巻き付け、その余端部を前記上部縦軸１８ｃに突設した二又状引掛具２１に引掛して固定される。勿論、該牛の前足固定具１８は左右双方の側扉１４，１４の前記開口部１７，１７の位置に設けられて該側扉１４，１４の開閉動作に支障を来さないように形成されている。
【００１５】
又、図４及び図５に示す如く、左右の下部フレーム２ｄ，２ｄの後端部に牛の後足固定具２２，２２が備えられている。該後足固定具２２は鍵型に折曲されて成り、基部である下部縦軸２２ａは前記下部フレーム２ｄの後端部に設けた筒状支持軸２２ｂに水平方向回動自在に枢支されて成り、更に、該縦軸２２ａの上端部に扇形盤２３を固設し、そして、該扇形盤２３の曲面近傍に多数の孔２３ａ，２３ａ…を開穿し、該孔２３ａ，２３ａ…のうち一つの孔２３ａにピン２４を挿通し、該ピン２４を前記下部フレーム２ｄの後端部に設けた開口筒２５に挿通して所定角に回動された前記後足固定具２２の方向を固定できるように構成されている。
【００１６】
又、該扇形盤２３から水平方向に延設される中軸２２ｃが設けられ、更に、該中軸２２ｃは外筒軸２２ｄ内を摺動自在に遊嵌され、該外筒軸２２ｄに複数個のピン孔２２ｅ，２２ｅ…を開穿し、一つのピン孔２２ｅにピン２２ｆを挿通して中軸２２ｃと外筒軸２２ｄとを固定できるように構成されて水平方向の長さ調整ができるように構成されている。更に又、該外筒軸２２ｄの先端部には上部縦軸２２ｇが立設され、該上部縦軸２２ｇは前記前足固定具１８と同様に上下高さ調整自在に構成されると共に、牛足載置片２２ｈ及び牛足固定片２２ｉ並びに卵形空所１９ａ，チェン２０ａ，二又状引掛片２１ａを有して前足固定具と全く同一の機能を有するが、之は後足の固定に用いられるのであり、従って、左右両側に備えられている事は当然である。又、前記後扉１６にも側扉１４と同様に開口部１７ａが設けられている。
【００１７】
又、該牛収容室３の内底部には略方形に形成された腹帯２６が敷設されている。該腹帯２６は該牛収容室３に入室した牛の腹部を下面より当接し、そして、該腹帯２６を上方へ吊り上げることによって牛も同時に地上に吊り上げることができるように構成されている。而して、該腹帯２６の左右両側縁には直線状の金具２７，２７が固設されており、該金具２７，２７の夫々の前後部に吊り上げ吊り下げ用のワイヤ２８，２８，２８ａ，２８ａが取り付けられ、エアシリンダ２９の駆動により、該ワイヤ２８，２８，２８ａ，２８ａが同一方向に吊り上げられ、又は吊り下げられるように構成されている。
【００１８】
そこで、牛の吊り上げ装置に用いる動力伝達機構について説明する。前記エアシリンダ２９は牛収容室３の天井部に前後方向に向って配設され、側方に備え付けられているエアタンク３０から圧力空気が供給される。而して、該エアシリンダ２９からの動力は図６の解説図に示すように、フレーム２に固設された該エアシリンダ２９のピストンロッド２９ａの先端部に第１チェン３１を連結し、そして、該第１チェン３１は牛収容室３の天井部フレーム２の左右方向に取り付けられた第１回転軸３２に軸着した第１ギヤ３３に巻回され、更に、該第１ギヤ３３に巻回された該第１チェン３１は前記エアシリンダ２９側のフレーム２に固設したスプリング３４の先端部に連結され、該スプリング３４によって該第１チェン３１は常時緊張されている。
【００１９】
又、前記第１回転軸３２には第２ギヤ３５が軸着されている。一方、牛収容室３の天井部フレーム２の前後端部近傍にて左右方向に第２回転軸３６及び第３回転軸３７が平行に対峙して取り付けられている。該第２回転軸３６の両端部には前部シーブ３８，３８が軸着され、第３回転軸３７の両端部にも後部シーブ３８ａ，３８ａが夫々前記前部シーブ３８，３８に対峙して軸着されている。
【００２０】
而して、前記腹帯２６の前部両側に取り付けられている前記ワイヤ２８，２８の上方部は前記前部シーブ３８，３８の夫々前面から巻回され乍らその端部が任意の点Ｐで固定してある。又、該腹帯２６の後部両側に取り付けられている前記ワイヤ２８ａ，２８ａの上方部は前記後部シーブ３８ａ，３８ａの背面から上面に及んで巻回され乍ら該後部シーブ３８ａ，３８ａと夫々対峙する前記前部シーブ３８，３８の夫々の下面から巻回されてその端部が任意の点Ｐにて固定されている。
【００２１】
又、前記第２回転軸３６の中央部には前記第２ギヤ３５に対峙して第３ギヤ３９が軸着されている。そして、該第２ギヤ３５と第３ギヤ３９との間に第２チェン４０が巻装され、第１回転軸３２の回転力を第２回転軸３６に伝達している。
【００２２】
更に又、前記エアシリンダ２９のピストンロッド２９ａの先端部に突部２９ｂを突設し、そして、該ピストンロッド２９ａが収縮して前記腹帯２６を所定高さ、即ち、該腹帯２６にて吊り上げられる牛が所定の高さに達したとき、該突部２９ｂがフレーム２等の所定の位置に設けられたリミットスイッチ４１に圧接して該リミットスイッチ４１をオンさせ、エアシリンダ２９の駆動を停止させると同時に後述の安全装置４２にて吊り上げられた牛が不慮落下しないように構成されている。
【００２３】
又、前記安全装置４２は図７に示す如く、前記第１回転軸３２又は第２回転軸３６の何れかに安全ギヤ４３を軸着し、そして、該安全ギヤ４３に噛合できる爪４４の基部をフレーム２に回動自在に枢着し、更に、該爪４４の上端部を前記安全ギヤ４３と反対側に付勢すべくスプリング４５にて引張している。又、前述せるようにリミットスイッチ４１がオンしたときにはフレーム２に取付けられている電磁切換弁４６がオンしてロッド４７が突出する。而して、該ロッド４７の先端部は前記爪４４の中央部に枢着されているので、該ロッド４７の突出により前記スプリング４５の引張力に抗して爪４４が回動し、前記安全ギヤ４３に噛合して所定高さまで吊り上げられた牛の落下を防止できるように構成されている。
【００２４】
斯くして、牛蹄を削蹄する際には、先ず、前後左右の夫々の扉を開放し、前記前足固定具１８，１８及び後足固定具２２，２２も横方向へ開いておく。そして、後部の牛の出入部１５から牛収容室３内に削蹄しようとする牛を入れる。然る後、前面の左右の夫々の扉を閉じる。このとき前面の扉は左右前扉４，４ａによって縦長の牛首遊挿孔１１が形成され、該牛首遊挿孔１１に前記牛の首が遊挿され、更に、左右及び後部の夫々の扉を閉じる。然るときは、該牛収容室３内に入室した牛はおとなしくなる。そこで、エアシリンダ２９を駆動させてピストンロッド２９ａをシリンダ内に引き込む。然るときは、第１チェン３１の駆動により第１回転軸３２が図５中時計方向に回転し、該第１回転軸３２に軸着されている第２ギヤ３５及び第２回転軸３６に軸着されている第３ギヤ３９も第２チェン４０により時計方向に回転する。更に、第２回転軸３６に軸着されている前部シーブ３８，３８も時計方向に回転して該前部シーブ３８，３８に巻回されているワイヤ２８，２８が引き上げられる。
【００２５】
一方、該前部シーブ３８，３８に対峙している後部シーブ３８ａ，３８ａには夫々対向する前部シーブ３８，３８の下面から後部シーブ３８ａ，３８ａの上面に向って前記ワイヤ２８ａ，２８ａが巻装されているので、後部シーブ３８ａ，３８ａを軸着している第３回転軸３７は反時計方向に回転する。依って、前後のワイヤ２８，２８及び２８ａ，２８ａは前記ピストンロッド２９ａの収縮作用によって上方へ移動し、該ワイヤ２８，２８及び２８ａ，２８ａに懸架されている腹帯２６が前記牛の腹に当接し乍ら、該牛を上方へ吊り上げる。そして、牛を所定高さまで吊り上げたとき、前記リミットスイッチ４１がオンしてエアシリンダ２９がオフし、前記吊り上げ動作が停止すると同時に前記安全装置４２が働いて牛の不慮の落下を防止する。勿論、前記リミットスイッチ４１の位置は牛群によって任意に変更できるものとする。
【００２６】
前述せる如く、牛を上方へ吊り上げた後、左右両側及び後部の扉を夫々開放し、そして、前足固定具１８，１８及び後足固定具２２，２２を牛収容室３側へ寄せて固定する。このとき、該固定具は角度及び長さ又は上下を任意に調整できるのですべての牛足の固定に適応できる。そこで、夫々の固定具にて固定された足は牛蹄が上方に向いて固定されており、且つ、削蹄する作業員の両手が自由に使えるので、該削蹄作業が極めて簡易迅速に施行されることが可能となる。
【００２７】
該削蹄作業が終了すれば、前記足の固定を解除し、更に、前記安全装置４２もボタン操作等によって解除し、エアシリンダ２９の操作レバーを操作することにより可及的速やかに牛を下降させて着地させる。然るときは、牛は自然に自己の前後の足によって立つことになる。そこで、前面の左右の扉を開放すれば、牛は自ら後退して牛収容室３から外部へ出る。斯くして、牛の削蹄作業は終了するのである。
【００２８】
而して、前記牛収容室３内に牛が収容されて牛が吊り上げられ、そして、前記牛首遊挿孔１１に牛首が遊挿されたとき、該牛は牛首を水平方向へ移動させることはできないが、該牛首遊挿孔１１が縦長に形成されている関係上、該牛は牛首を上下方向に対しては自在に移動させることができる。このとき、牛は習性上、牛首の上下動に伴って牛の前後の足も躍動して牛足固定具１８，１８及び２２，２２に牛足の力が負荷され、そのために牛足の固定が困難となる場合もあり、更に、一旦牛足を牛足固定具１８，１８及び２２，２２に固定しても、前述したように牛首の上下動によって牛足が躍動し、該牛足が前記牛足固定具１８，１８及び２２，２２並びに周辺器物を損壊させると云うことがある。
【００２９】
そこで、一旦、牛首を牛首遊挿孔１１に遊挿したときには、牛首の体形に応じて任意に高さ位置に設定された本発明の規制杆４８を該牛首遊挿孔１１の適正の高さ位置に装架し、そして、牛首が上下方向へ自在に移動できないように規制する。
【００３０】
而して、該規制杆４８は、シリンダ４９と、該シリンダ４９の一端部に伸縮自在に嵌挿されている爪片５０と、該シリンダ４９の他端部に突設した軸片５１、並びに該シリンダ４９内に介装され、前記爪片５０を外方へ付勢するためのスプリング５２とから成る。
【００３１】
一方、フレーム２の前面に立設されている片方の縦フレーム２ｃに、多数のラチェット爪５３ａ，５３ａ…を縦方向に並設されて成るラチェット片５３を取付ける。而も、該ラチェット片５３の該縦フレーム２ｃに対する取付位置は上下のボルト孔５３ｂ，５３ｂ…を介して任意に変更できるものとする。而して、該ラチェット片５３は前後にガイド５３ｃ，５３ｃを縦方向に対峙して設け、そして、前記ラチェット爪５３ａ，５３ａ…は該ガイド５３ｃ，５３ｃの間に設けられている。
【００３２】
又、該フレーム２の前面に立設されている他方の縦フレーム２ｃに、縦方向に多数の取付孔５４ａ，５４ａ…を開穿した板体５４ｂ，５４ｂを前後に対峙させて成る前記シリンダ４９の枢支片５４を取付ける。勿論、前記前後の板体５４ｂ，５４ｂに開穿した夫々の取付孔５４ａ，５４ａ…は前後孔芯が一致していることは当然である。
【００３３】
斯くして、シリンダ４９の一端に突設している軸片５１の先端部に設けた枢支孔片５１ａを前後の取付孔５４ａ，５４ａ間に挿入し、ピンＰ等を用いて該シリンダ４９を該枢支片５４に枢支して上下回動自在に形成する。而も、該枢支片５４の該縦フレーム２ｃに対する取付位置は、上下のボルト孔５４ｃ，５４ｃ…を介して任意に変更でき、且つ、該シリンダ４９の枢支部の取付位置も前記取付孔５４ａの選定により任意に変更できるものとする。然るときは、前記ラチェット片５３の取付位置の変更と相俟って牛の体形に対応させて、牛首の遊挿位置を所定位置に設定することができる。
【００３４】
又、前記シリンダ４９の前記爪片５０の嵌挿位置にスリーブ５５を長手方向に開穿し、そして、該スリーブ５５を介して該シリンダ４９内に把持片５６を挿入し、更に、該把持片５６の先端部を前記爪片５０に固設する。而して、前記爪片５０が前記スプリング５２の付勢により前記ラチェット爪５３ａに噛合しているとき、この噛合を脱して該規制杆４８を上方へ回動し、該規制杆４８による牛首遊挿孔１１に対する上下長さの規制を解除する際、該把持片５６を把持して該シリンダ４９の中心方向へ摺動せしめれば、該爪片５０もシリンダ４９内を中心方向へ摺動して前記ラチェット爪５３ａに対する噛合を脱することになる。
【００３５】
又、該シリンダ４９のラチェット片５３側には突片５７が突設されており、そして、該突片５７にロープ（図示せず）等を取付け、フレーム２の上方部にリール（図示せず）等を回転自在に枢着し、該リールに該ロープを巻回し乍ら下方へ垂下せしめ、そして、該ロープを引張することにより該シリンダ４９等から成る規制杆４８を上方へ回動させ、そして、縦フレーム２ｃに沿設した状態に維持させることができるようにしてもよい。又、手動によって該規制杆４８の回動操作を行ってもよい。
【００３６】
而して、該規制杆４８は、前記取付孔５４ａ，５４ａ…のうち任意の取付孔５４ａが選択されて枢支される。そして、当初は上方へ回動されて縦フレーム２ｃに沿設されている。そこで、牛蹄を削蹄しようとするときには、該牛収容室３内に牛が収容され、そして、該牛は吊り上げられ、更に、前面の左右の扉枠５及び５ａを回動させて牛首遊挿孔１１を形成する。然る後、前記規制杆４８を下方へ回動させて牛首の上面に当接させ、ラチェット爪５３ａに爪片５０が噛合して該規制杆４８が所定位置で固定される。然るときは、牛首遊挿孔１１の上下の長さが丁度牛首を遊嵌できる程度の長さに規制され、依って、牛は牛首を上下左右何れにも自在に動かすことができなくなる。斯かる場合には、牛の習性上、牛足も静止することになり、依って、牛足固定具１８，１８及び２２，２２に対する牛足の固定も容易となると共に、一旦、固定された牛足は牛首の動きの規制によってその力を牛足固定具１８，１８及び２２，２２に負荷させることがないので、牛足及び牛足固定具１８，１８及び２２，２２又はその周辺器物等を損傷させるようなことは一切なくなる。
【００３７】
而して、削蹄作業が終了したときには、爪片５０に固設してある把持片５６を把持して該爪片５０をシリンダ４９の中心方向に摺動させ、該爪片５０のラチェット爪５３ａに対する噛合を脱せしめ乍ら規制杆４８を上方へ回動して縦フレーム２ｃに沿設すると共に、前扉枠５及び右扉枠５ａを左右に回動して開いておき、次の削蹄動作を待つことになる。
【００３８】
尚、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。
【００３９】
【発明の効果】
この発明は上記一実施の形態にて詳述せる如く、牛蹄削蹄装置の牛収容室に牛を収容し、そして、該牛を吊り上げ、更に、左右の前扉を中央側へ回動して牛首遊挿孔内に牛首を遊挿した後、規制杆を下方へ回動して牛首遊挿孔の上下の長さを規制し、該牛首の上下動を規制する。勿論該牛首は水平方向の動きも、幅方向は予め狭く形成されている牛首遊挿孔によって規制されているので、該牛は牛首を上下左右の何れの方向にも動かすことができない。
【００４０】
斯くして、牛足も牛首の動き規制に順応して静止した状態となり、牛足固定具に対する牛足の固定も容易迅速に行われ、且つ、固定した後に於ても牛足の力が該牛足固定具に負荷されることがないので、極めて安全確実に削蹄作業が施工でき、且つ、作業環境も改善され、削蹄の作業性が向上し、コストダウンにも寄与する等、正に著大なる効果を奏する発明である。

Therefore, it is natural that it is provided on both the left and right sides. Further, the rear door 16 is also provided with an opening 17 a in the same manner as the side door 14.
[0017]
An abdominal band 26 formed in a substantially square shape is laid on the inner bottom of the cow housing chamber 3. The abdomen 26 is configured such that the abdomen of the cow entering the cow storage chamber 3 abuts from the lower surface, and the cattle can be lifted to the ground at the same time by lifting the abdomen 26 upward. Thus, straight metal fittings 27, 27 are fixed to the left and right side edges of the abdominal band 26, and the wires 28, 28, 28a for lifting and hanging on the front and rear parts of the metal fittings 27, 27, respectively. 28a is attached, and the wire 28, 28, 28a, 28a is lifted or hung in the same direction by driving of the air cylinder 29.
[0018]
Therefore, a power transmission mechanism used for a cow lifting device will be described. The air cylinder 29 is disposed on the ceiling of the cow housing chamber 3 in the front-rear direction, and is supplied with pressurized air from an air tank 30 provided on the side. Thus, the power from the air cylinder 29 connects the first chain 31 to the tip of the piston rod 29a of the air cylinder 29 fixed to the frame 2, as shown in the explanatory view of FIG. The first chain 31 is wound around a first gear 33 attached to a first rotating shaft 32 attached in the left-right direction of the ceiling frame 2 of the cow housing chamber 3, and is further wound around the first gear 33. The rotated first chain 31 is connected to a tip end of a spring 34 fixed to the frame 2 on the air cylinder 29 side, and the first chain 31 is always tensioned by the spring 34.
[0019]
A second gear 35 is attached to the first rotating shaft 32. On the other hand, a second rotating shaft 36 and a third rotating shaft 37 are attached in parallel in the left-right direction in the vicinity of the front and rear end portions of the ceiling frame 2 of the cow housing chamber 3. Front sheaves 38 and 38 are attached to both ends of the second rotary shaft 36, and rear sheaves 38a and 38a are also opposed to the front sheaves 38 and 38 on both ends of the third rotary shaft 37, respectively. It is attached to the shaft.
[0020]
Thus, the upper portions of the wires 28, 28 attached to both sides of the front portion of the abdominal band 26 are wound from the front surfaces of the front sheaves 38, 38, respectively, while their end portions are at arbitrary points P. It is fixed. Further, the upper portions of the wires 28a, 28a attached to both sides of the rear portion of the abdominal band 26 are wound from the back surface to the upper surface of the rear sheaves 38a, 38a so as to face the rear sheaves 38a, 38a, respectively. The front sheaves 38 and 38 are wound from the lower surfaces of the front sheaves 38 and 38, and their ends are fixed at arbitrary points P.
[0021]
A third gear 39 is attached to the center of the second rotating shaft 36 so as to face the second gear 35. A second chain 40 is wound between the second gear 35 and the third gear 39 to transmit the rotational force of the first rotating shaft 32 to the second rotating shaft 36.
[0022]
Further, a protrusion 29b is provided at the tip of the piston rod 29a of the air cylinder 29, and the piston rod 29a contracts to lift the belly band 26 at a predetermined height, that is, the belly band 26. When the cow reaches a predetermined height, the projection 29b comes into pressure contact with a limit switch 41 provided at a predetermined position such as the frame 2 to turn on the limit switch 41 and stop the driving of the air cylinder 29. At the same time, the cow lifted by the safety device 42 described later is configured not to accidentally fall.
[0023]
Further, as shown in FIG. 7, the safety device 42 has a safety gear 43 mounted on either the first rotating shaft 32 or the second rotating shaft 36, and a base portion of a claw 44 that can mesh with the safety gear 43. Is pivotally attached to the frame 2 and is further pulled by a spring 45 to urge the upper end of the claw 44 to the opposite side of the safety gear 43. Further, as described above, when the limit switch 41 is turned on, the electromagnetic switching valve 46 attached to the frame 2 is turned on and the rod 47 projects. Thus, since the tip of the rod 47 is pivotally attached to the central portion of the claw 44, the projection of the rod 47 rotates the claw 44 against the tensile force of the spring 45, thereby It is configured so that the cattle that are engaged with the gear 43 and lifted to a predetermined height can be prevented from falling.
[0024]
Thus, when shaving the cow hoof, first, the front, rear, left and right doors are opened, and the front foot fixing devices 18 and 18 and the rear foot fixing devices 22 and 22 are also opened in the lateral direction. Then, the cow to be trimmed is put into the cow housing chamber 3 from the rear cow doorway 15. After that, close the left and right doors on the front. At this time, the front door has left and right front doors 4, 4 a to form a vertically long bovine neck insertion hole 11, and the cow's neck is loosely inserted into the bovine neck free insertion hole 11, and the left and right and rear doors are closed. When this happens, the cows that enter the cow housing room 3 become silent. Therefore, the air cylinder 29 is driven to retract the piston rod 29a into the cylinder. In this case, the first rotation shaft 32 is rotated clockwise in FIG. 5 by driving the first chain 31, and the second gear 35 and the second rotation shaft 36 that are attached to the first rotation shaft 32 are rotated. The third gear 39 attached to the shaft is also rotated clockwise by the second chain 40. Further, the front sheaves 38 and 38 attached to the second rotating shaft 36 also rotate clockwise, and the wires 28 and 28 wound around the front sheaves 38 and 38 are pulled up.
[0025]
On the other hand, the rear sheaves 38a, 38a facing the front sheaves 38, 38 are wound with the wires 28a, 28a from the lower surfaces of the front sheaves 38, 38 facing each other toward the upper surfaces of the rear sheaves 38a, 38a. Since it is mounted, the third rotating shaft 37 pivotally attached to the rear sheaves 38a, 38a rotates counterclockwise. Therefore, the front and rear wires 28, 28 and 28a, 28a are moved upward by the contracting action of the piston rod 29a, and the abdominal band 26 suspended on the wires 28, 28 and 28a, 28a is brought into contact with the belly of the cow. When in contact, the cow is lifted upward. When the cow is lifted to a predetermined height, the limit switch 41 is turned on, the air cylinder 29 is turned off, and the lifting operation is stopped. At the same time, the safety device 42 is activated to prevent the cow from being accidentally dropped. Of course, the position of the limit switch 41 can be arbitrarily changed depending on the herd.
[0026]
As described above, after lifting the cow upward, the left and right and rear doors are opened, and the forefoot fixing devices 18 and 18 and the rear foot fixing devices 22 and 22 are moved toward the cow housing chamber 3 and fixed. . At this time, since the fixing tool can be arbitrarily adjusted in angle and length or up and down, it can be adapted to fixing all cow legs. Therefore, the foot fixed by each fixing tool is fixed with the cow hoof facing upwards, and both hands of the operator who trims the hoof can be used freely, so the hoofing operation is performed very simply and quickly. Can be done.
[0027]
When the hoofing operation is completed, the fixing of the foot is released, the safety device 42 is also released by operating a button, and the cow is lowered as soon as possible by operating the operation lever of the air cylinder 29. Let it land. When that happens, cows will naturally stand on their front and back legs. Therefore, if the left and right doors on the front are opened, the cow will recede himself and go out of the cow housing chamber 3. Thus, the hoof cutting operation of the cow is finished.
[0028]
Thus, when the cow is housed in the cow housing chamber 3 and the cow is lifted, and the cow head is loosely inserted into the cow neck free insertion hole 11, the cow moves the cow head in the horizontal direction. However, the cow can freely move the cow's neck in the vertical direction because the cow's neck free insertion hole 11 is formed vertically long. At this time, the cow has a habit, and the cow's front and rear legs also move up and down as the cow's neck moves up and down, and the cow's foot fixing tools 18, 18 and 22, 22 are loaded with the power of the cow's legs. In addition, once the cow's foot is fixed to the cow foot fixing devices 18, 18, 22 and 22, the cow's foot is moved up and down by the vertical movement of the cow's neck as described above. It may be said that the said cow leg fixing tools 18, 18, and 22, 22 and peripheral equipment are damaged.
[0029]
Therefore, once the cow's neck is loosely inserted into the cow's neck free insertion hole 11, the restriction rod 48 of the present invention, which is arbitrarily set at the height position according to the body shape of the cow's neck, is set to the appropriate height of the cow neck free insertion hole 11. Mount in position, and restrict the cow head from moving freely in the vertical direction.
[0030]
Thus, the restriction rod 48 includes a cylinder 49, a claw piece 50 that is telescopically inserted into one end portion of the cylinder 49, a shaft piece 51 that projects from the other end portion of the cylinder 49, and A spring 52 is provided in the cylinder 49 and biases the claw piece 50 outward.
[0031]
On the other hand, a ratchet piece 53 comprising a large number of ratchet claws 53a, 53a,... Arranged in the vertical direction is attached to one vertical frame 2c standing on the front surface of the frame 2. The mounting position of the ratchet piece 53 with respect to the vertical frame 2c can be arbitrarily changed through the upper and lower bolt holes 53b, 53b. Thus, the ratchet piece 53 is provided with the guides 53c, 53c facing each other in the longitudinal direction, and the ratchet claws 53a, 53a,... Are provided between the guides 53c, 53c.
[0032]
Also, the cylinder 49 is formed by opposing the front and rear plates 54b, 54b having a plurality of mounting holes 54a, 54a ... in the vertical direction on the other vertical frame 2c standing on the front surface of the frame 2. The pivot piece 54 is attached. Of course, it is natural that the mounting holes 54a, 54a... Opened in the front and rear plate bodies 54b, 54b have the same front and rear hole cores.
[0033]
Thus, the pivot hole piece 51a provided at the tip of the shaft piece 51 protruding from one end of the cylinder 49 is inserted between the front and rear mounting holes 54a, 54a, and the cylinder 49 is used using the pin P or the like. Is pivotally supported on the pivot piece 54 so as to be pivotable up and down. However, the mounting position of the pivot piece 54 with respect to the vertical frame 2c can be arbitrarily changed via the upper and lower bolt holes 54c, 54c... And the mounting position of the pivot section of the cylinder 49 is also the mounting hole 54a. It can be changed arbitrarily by selection. In this case, the loose insertion position of the cow's neck can be set to a predetermined position in association with the change of the mounting position of the ratchet piece 53 in accordance with the body shape of the cow.
[0034]
Further, a sleeve 55 is opened in the longitudinal direction at the insertion position of the claw piece 50 of the cylinder 49, and a gripping piece 56 is inserted into the cylinder 49 via the sleeve 55. Further, the gripping piece The tip of 56 is fixed to the claw piece 50. Thus, when the claw piece 50 is engaged with the ratchet claw 53a by the urging of the spring 52, the engagement is released and the restriction rod 48 is rotated upward. When the restriction of the vertical length with respect to the insertion hole 11 is released, if the grip piece 56 is gripped and slid in the center direction of the cylinder 49, the claw piece 50 also slides in the cylinder 49 in the center direction. Thus, the meshing with the ratchet pawl 53a is released.
[0035]
Further, a projecting piece 57 projects from the ratchet piece 53 side of the cylinder 49, and a rope (not shown) or the like is attached to the projecting piece 57, and a reel (not shown) is provided above the frame 2. ) Etc. are pivotally attached, the rope is wound around the reel, and the rope is suspended downward, and by pulling the rope, the regulating rod 48 including the cylinder 49 is rotated upward, And you may make it maintain in the state installed along the vertical frame 2c. Further, the turning operation of the restriction rod 48 may be performed manually.
[0036]
Thus, the restriction rod 48 is pivotally supported by selecting an arbitrary attachment hole 54a among the attachment holes 54a, 54a. And initially, it is rotated upward and is installed along the vertical frame 2c. Therefore, when cutting the cow hoof, the cow is housed in the cow housing chamber 3, the cow is lifted, and the front left and right door frames 5 and 5a are rotated to move the cow neck. The insertion hole 11 is formed. Thereafter, the restriction rod 48 is rotated downward so as to come into contact with the upper surface of the cow neck, the claw piece 50 is engaged with the ratchet claw 53a, and the restriction rod 48 is fixed at a predetermined position. In such a case, the vertical length of the bovine neck free insertion hole 11 is restricted to a length that allows the bovine neck to be loosely fitted, so that the cow cannot freely move the bovine neck vertically and horizontally. In such a case, due to the behavior of the cow, the cow leg is also stationary, so that it is easy to fix the cow leg with respect to the cow leg fixing devices 18, 18 and 22, 22 and is once fixed. Since the bull's feet do not apply the force to the bull foot fixing devices 18, 18 and 22, 22 due to the restriction of the movement of the bull's neck, the bull feet and the bull foot fixing devices 18, 18 and 22, 22 or their peripheral equipment, etc. Nothing will damage it.
[0037]
Thus, when the hoofing operation is completed, the gripping piece 56 fixed to the claw piece 50 is gripped and the claw piece 50 is slid toward the center of the cylinder 49, and the ratchet claw of the claw piece 50 is After releasing the mesh with 53a, the regulating rod 48 is rotated upward to be installed along the vertical frame 2c, and the front door frame 5 and the right door frame 5a are rotated left and right to be opened, and the next cutting is performed. It will wait for hoof movement.
[0038]
It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified one.
[0039]
【The invention's effect】
In the present invention, as described in detail in the above embodiment, the cow is housed in the cow housing room of the cow hoof hoof device, the cow is lifted, and the left and right front doors are rotated to the center side. Then, after the cow neck is loosely inserted into the cow neck free insertion hole, the vertical length of the cow neck free insertion hole is restricted by rotating the restriction rod downward to restrict the vertical movement of the cow neck. Of course, since the cow's neck is also restricted in movement in the horizontal direction by the cow's neck free insertion hole formed narrow in advance in the width direction, the cow cannot move the cow's neck in any direction, up, down, left and right.
[0040]
Thus, the bull's foot also becomes stationary in conformity with the movement restriction of the bull's neck, and the bull's foot can be easily and quickly fixed to the bull's foot fixing tool. Since it is not loaded on the cow leg fixing tool, it is possible to construct the hoofing work very safely and reliably, improve the work environment, improve the workability of the hoofing, and contribute to cost reduction. It is an invention that has a remarkable effect.
