EXCAVATION AGITATION DEVICE WITH CO-ROTATION PREVENTION BLADE
PROBLEM TO BE SOLVED: To provide an excavation agitation device with a co-rotation prevention blade which can suppress an adverse effect even if foreign matters exist.SOLUTION: This excavation agitation device with a co-rotation prevention blade comprises: a rotating shaft 2 which rotates in the ground; an excavation blade 3 which is protrusively arranged at a lower end of the rotating shaft 2, and excavates sediment; and the co-rotation prevent blade 10 which is arranged at an upper part apart from the excavation blade 3 at the rotating shaft 2 by a prescribed distance, and has a boss part 10a which circulates around the rotating shaft 2, and is loosely fit to the rotating shaft 2. The co-rotation prevention blade 10 is formed so that its tip is separated from the excavation blade 3 compared with a base end which approximates the boss part 10a.SELECTED DRAWING: Figure 2
【課題】 異物が存在してもその悪影響を抑制できる共回り防止翼付き掘削撹拌装置を提供する。【解決手段】 本装置は、地中で回転する回転軸２と、回転軸２の下端部に突設され土砂を掘削する掘削翼３と、回転軸２において掘削翼３よりも所定距離だけ上方に設けられ、回転軸２を周回し回転軸２に対して遊嵌されるボス部１０ａを有する共回り防止翼１０とを備える共回り防止翼付き掘削撹拌装置であって、共回り防止翼１０は、ボス部１０ａに近接する基端部に比べ、先端部が掘削翼３から遠ざかる形状をなすように形成されている。【選択図】 図２
