To improve an excavation and stirring efficiency of an excavation and stirring device compared to conventional devices.SOLUTION: An excavation and stirring device comprises: a shaft body that can rotate around an axis extending in the vertical direction as a center of rotation; a pair of excavation blades extending in opposite directions from a region on a lower end of the shaft body along a first plane that intersects the vertical direction; a plurality of anti-corotation blades extending radially from a region on the shaft body above the excavation blades along the first plane; and a plurality of stirring blades extending radially from a region on the shaft body above the anti-corotation blades along the first plane. The excavation blades, the anti-corotation blades, and the stirring blades are positioned such that a sum of a distance h1 between the excavation blade and the anti-corotation blade in the vertical direction and a distance h2 between the anti-corotation blade and the stirring blade is a value selected from the range of 0.2 to 0.35 (=A/(h1+h2)) with respect to a diameter A of an imaginary circle drawn by a tip of the excavation blade rotating around the axis.SELECTED DRAWING: Figure 1
【課題】掘削攪拌装置において従来よりも掘削・攪拌効率を向上させる。【解決手段】上下方向に延びる軸線を回転中心として回転可能な軸体と、前記軸体における下端側の領域から上下方向と交差する第１平面に沿ってそれぞれ反対方向に延びる一対の掘削翼と、前記軸体において前記掘削翼よりも上方の領域から前記第１平面に沿ってそれぞれ放射状に延びる複数の共回り防止翼と、前記軸体において前記共回り防止翼よりも上方の領域から前記第１平面に沿ってそれぞれ放射状に延びる複数の攪拌翼と、を備え、前記掘削翼、前記共回り防止翼および前記攪拌翼は、軸線周りに回転する前記掘削翼の先端で描かれる仮想円の直径Ａに対し、上下方向に沿った前記掘削翼と前記共回り防止翼との間隔ｈ１および前記共回り防止翼と前記攪拌翼との間隔ｈ２の合計値が、０．２～０．３５（＝Ａ／（ｈ１＋ｈ２））の範囲から選択された値となる位置関係となっている。【選択図】図１
