STUMP REMOVING APPARATUS
To prevent the entire stump removing apparatus from being damaged by an impact of a solid matter in ground.SOLUTION: A stump removing apparatus comprises: a drum member 3 which bites into a ground around a stump while digging the ground; elevating drive means for elevating the drum member 3; rotary driving means 7 for rotating the drum member 3 in forward and backward directions; and a plurality of cutter members 4 which are attached to a lower end part of the drum member 3 with a gap, and cut lateral roots of the stump. The cutter members 4 are tiltable with respect to the drum member 3 by a predetermined value or more of resistance of the ground .SELECTED DRAWING: Figure 2
【課題】地盤中の固形物による衝撃で根株除去装置全体が損傷することを防止する。【解決手段】根株除去装置は、地盤掘りを行いながら根株の周囲の地盤に食い込むドラム部材３と、ドラム部材３を昇降させる昇降駆動手段と、ドラム部材３を正逆方向に回転させる回転駆動手段７と、ドラム部材３の下端部に間隔を有して取り付けられ、根株の側根の切断を行う複数のカッター部材４とを備える。カッター部材４は地盤の所定以上の抵抗によってドラム部材３に対し傾動可能となっている。【選択図】図２
