STUMP REMOVAL CONSTRUCTION METHOD AND STUMP REMOVAL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide stump removal construction methods and stump removal apparatus capable of simplifying stump removal operation to improve handling properties and operativity, without enlarging the motorization accompanied by drawing out stumps nor the weight of component members due to needing no operation of drawing out a stump from the ground.;SOLUTION: A stump cutter 4 has a perforation drill 42 extending in an axial direction, at a lower side, and a crush edge 43 extending in the direction which intersects an axial direction, at an upper side, the stump being allowed to descend while rotating. A perforation drill 42 digs and bites a stump 9, a crush edge 43 cuts into the stump 9 to crush the stump 9 following the biting state of the perforation drill 42, and a drum member 3 prevents scattering of fragments of the stump to around at the time of crushing of the stump 9.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
