Description

【001】
【発明の属する技術分野】
本発明はパワーショベルなどの土木機械のアームに取付け、内部に掬い入れたコンクリート塊などの解体廃棄物を細かく砕くバケット型破砕装置に関する。
【002】
【従来の技術】
バケット状本体フレーム内に、放射状の縦枠に複数段の横枠を結合した逆円錐台形の枠体を固定し、その内部に回転破砕器を設けた破砕装置は、建造物の解体で発生するコンクリート塊などの破砕に使用されている。
従来の破砕装置は、中央部の回転破砕器に主たる破砕機能をもたせ、外側の逆円錐台形枠体は主として解体物の篩い分けに使用している。
【003】
この種の破砕装置は、逆円錐台形枠体にも凹凸部を設けているが、縦枠が上方から中心に向けて真っ直に延びる放射枠であるため、逆円錐台形枠体での破壊力が弱い。また、コンクリート塊を逆円錐台形枠体の壁面に係止する力が弱いため、回転破砕器の破砕力がコンクリート塊に伝わりにくく、効率のよい破砕作用が得られないという問題があった。
【004】
従って、本発明の第1の目的は、回転破砕器とその外側の逆円錐台形枠体の両部材に破壊機能をもたせ、且つ、両部材の破壊力を無駄なく利用することができる破砕装置を提供することにある。
【005】
本発明の他の目的は、バケット本体フレームの内部に入れたコンクリート塊を上方から下方に向けて次第に小さい塊に破砕し、これにより、回転破砕器に過大な負荷がかからないようにした上記破砕装置を提供することにある。
【006】
【課題を解決するための手段】
上記第1の目的を達成するために、本発明は、上端を開放したバケット状本体フレームの内部に、複数の放射状縦枠を上下複数段の横枠で結合した逆円錐台形の破砕枠体を固定するとともに、上下複数段の破砕歯を突設した回転破砕器を前記破砕枠体内部に配設した破砕装置において、前記破砕枠体の縦枠を、上下複数段の横枠の内側に、回転破砕器の回転方向の逆方向へ傾斜させて螺旋状に配設したことを特徴とする。
【007】
逆円錐台形破砕枠体での破壊力を増強するために、好ましくは破砕枠体の上記縦枠を角形鋼材で形成する。
【008】
上記他の目的を達成するための本発明は、上記破砕装置において、回転破砕器の破砕歯の横方向突出長さを下段から上段に向けて次第に長くするとともに、回転破砕器の下方に、落下孔を有する中底板を固設し、この中底板に対向する回転破砕器の外側底面に、突出長さの異なる複数の破砕突起を形成したことを特徴とする。
【009】
【発明の実施の形態】
以下、本発明の実施例を添付図面に基づいて説明する。
本発明の破砕装置1は、図1及び図2に示すように、バケット状の本体フレーム2を有し、この本体フレーム2は上端を開放させたバケット状フレームの一側に掬い部3を有するとともに、他側にステイ4を一体に有し、このステイ4を土木機械のアームとリンクに連結するようになっている。
【010】
本体フレーム2は底部付近に中底板5を固設してあり、この中底板5と本体フレーム2の上端の間に、逆円錐台形の破砕枠体6が固定されている。
破砕枠体6の内部中心に回転破砕器7が垂直に配設されており、この回転破砕器7は中底板5の下方の本体フレーム底部に固定した油圧モータなどの回転駆動装置8によって矢印(図1)方向に回転するようになっている。
【011】
破砕枠体6は、斜め上方に開くようにして放射状に配した複数の縦枠9を複数段の横枠10a、10b、10cで結合した逆円錐台形の枠体に形成されており、各々の縦枠9は、回転破砕器7の回転方向と逆方向へ傾斜させて放射状に配列され、全体として回転破砕器7の回転方向と逆方向の螺旋状縦枠群を形成している。
【012】
縦枠9は好ましくは断面が角形の鋼材からなり、角材角部が破砕枠体6の内側に露出するように配列されている。
【013】
破砕枠体6の横枠10a、10b、10cは角形の鋼材からなり、放射状縦枠9群の外側に環状に結合されているとともに、図の実施例では上下横枠間の間隔は下方に向かうにしたがって狭くしてある。
【014】
回転破砕器7は側面に複数の破砕歯11を上下多段に突設してあり、回転破砕器7と一体に回動する破砕歯11により本体フレーム2内に入れたコンクリート塊を破砕するように組付けられている。
これらの破砕歯11は、好ましくは、下段から上段に向かうに従って横方向の突出長さを長くし、これにより、大きな塊が本体フレームの上方に保持され次第に小さく砕かれながら下方へ送られるようにしてある。
また、破砕歯11は下段に向かうにつれて間隔を狭め、これにより、下位にゆくにしたがって次第に細かく砕くようになっている。
また、破砕歯11の突出長さは下段になるにしたがい短くし、これにより、大きな塊が本体フレームの上方に保持され次第に小さく砕かれながら下方へ送られるようにしてある。
【015】
回転破砕器7は底面と中底板5の間に空間が形成されるようにして設置されており、この底面に複数の破砕突起12が中底板5に向けて固設されている。
この破砕突起12は回転破砕器7と一体に回動することにより、回転破砕器7の底面と中底板5の間に入ってきた被破砕物をすりつぶすようにして細破砕し、細かに砕いた後、中底板5の孔13から下方へ落下させるようになっている。
なお、中底板5は全面に多数の孔13が開口しており、逆円錐台形破砕枠体6を通って落下してきた破砕処理物が孔13から本体フレーム2の底へ落下するようになっている。
また、図3に判り易く示すように、本体フレーム2の底板14は多数の開口部15が格子状に形成されており、本体フレーム2の底に落下してきた破砕処理物はこの開口部15から外部へ排出される。
【016】
回転破砕器7の底面に突設した破砕突起12は、突出長さの異なる複数の破砕突起群からなる。
これらの破砕突起群は突出長さの異なる破砕突起12を不規則に配列してもよく、また、回転方向の前側から後側へ向けて突出長さが次第に長くなるようにしてもよい。後者の場合は、回転破砕器7の破砕突起12群で被破砕物を圧縮しながら砕くことができる。
【017】
なお、図は省略したが、逆円錐台形破砕枠体6の縦枠9は、中間部を破砕枠体2の内側へ湾曲あるいは屈曲させ、これにより、被破砕物との衝突破壊効果を高めてもよい。
【018】
次に本発明の破砕装置の作用を説明する。
破砕装置1の本体フレーム2内に投入されたコンクリート塊などの被破砕物は回転破砕器7の破砕歯11によって砕かれる。
この場合、回転破砕器7の外側に固定されている逆円錐台形破砕枠体6の縦枠9は回転破砕器7の回転方向の逆方向へ傾斜させて放射状に配設してあるので、回転破砕器7の回転によって飛ばされた被破砕物は、回転方向とは逆方向に傾斜している縦枠9に向き合う角度で衝突し、強い破壊力を受けるとともに、被破砕物を破砕枠体6内に押し返す力が働くので回転破砕器7の破砕歯11は被破砕物を効率よく砕く。
縦枠9に角形鋼材を使用した場合はこの傾向が一層顕著になる。
【019】
回転破砕器7の破砕歯11の突出長さは最上段が最も長く、下段になるにしたがって短くなっているので大きい塊は上段に溜り、次第に細かく砕かれながら下方へ送り込まれる。
【020】
また、破砕歯11は下段になるにしたがい上下間隔が狭くなっているので破砕粒子が次第に細かになる。
【021】
【効果】
本発明の破砕装置は、回転破砕器だけでなく、逆円錐台形破砕枠体も強力な破壊機能を有するので、総体的な破砕効果が著しく向上する。とくに、傾斜させた破砕枠体がコンクリート塊の移動を抑制するので回転破砕器の破壊力を無駄なく利用することができる。
【022】
本体フレームの内部でコンクリート塊の大割り、小割り、粉砕作用が分担され、上方から下方へ向けて次第に細かく破砕される。このため、局所的な過大負荷がかからないので破砕装置の耐久性もよくなる。
