Claims (1)
- 作業機のアームの先端に下顎を起伏自在に装着すると共に前記下顎に上顎を開閉可能に装着し、前記下顎及び前記上顎間に設けた油圧シリンダのピストンロッドの進退駆動により前記下顎に対して前記上顎を開閉駆動させてコンクリート塊を破砕するコンクリート破砕機において、
前記下顎にリンクを介して連結し、かつ、前記上顎に前端部をピン結合して、前記油圧シリンダのピストンロッドの外側を常時覆う位置で、前記上顎の開閉動作に伴って揺動する保護カバーと、前記保護カバーに取付けられ、磁力によって鉄筋屑を吸着可能な磁石とを備え、
下顎及び上顎の連結箇所と、上顎及び保護カバーの連結箇所と、保護カバー及びリンクの連結箇所と、リンク及び下顎の連結箇所とを連結したリンク機構を構成し、上顎を揺動させるシリンダによる上顎の開状態乃至閉状態において、保護カバーに付設された磁石を吸着作業姿勢状態に維持することを特徴とするコンクリート破砕機。
