UNDERGROUND OBSTACLE REMOVING DEVICE
PROBLEM TO BE SOLVED: To provide an underground obstacle removing device capable of ensuring strong bite force and efficiently removing an obstacle with a large diameter.SOLUTION: An underground obstacle removing device comprises: a grab holding part 5 which is disposed inside a cylindrical casing 100 installed while rotating around an axis so as to surround an underground obstacle and drills and engages between an inner periphery of the cylindrical casing and an outer periphery of the underground obstacle; a pair of grab shells 7 which are formed into a semi-arc shape and have a pivot shaft 18 at both ends and a cutting blade 21 at a lower edge and are rotatably disposed around the pivot shaft 18 under the grab holding part 5; cutting blade rotating means 13, 14 which are disposed above the grab shells 7 and rotate the grab shells 7; and an actuation lever 15 which connects a lever connection position 22 on the opposite side of the cutting blades 21 of the grab shells 7 and the cutting blade rotating means 13, 14. Rising of the actuation lever 15 causes the grab shells 7 to rotate to the inner periphery side.SELECTED DRAWING: Figure 1
【課題】 強い咬合力を確保することができ、大径の障害物を効率よく撤去することができる地中障害物撤去装置を提供する。【解決手段】 地中障害物を囲繞するように軸周りに回転しながら建て込まれる筒状ケーシング１００の内側に配置され、筒状ケーシング内周と前記地中障害物外周との間に掘進嵌入するグラブ保持部５と、両端に枢着軸１８を有し下縁に切断刃２１を有する半円弧状に構成され、前記グラブ保持部５の下部に前記枢着軸１８周りに回動自在に配置された一対のグラブシェル７と、前記グラブシェル７よりも上方位置に設けられ、前記グラブシェル７を回動させる切断刃回動手段１３，１４と、前記グラブシェル７の前記切断刃２１の反対側のレバー連結位置２２と前記切断刃回動手段１３，１４とを連結する動作レバー１５とを有し、前記動作レバー１５が上昇することで前記グラブシェル７が内周側に回動する。【選択図】 図１
