CRUSHED STONE PILE FORMING ATTACHMENT AND CRUSHED STONE PILE FORMING DEVICE EQUIPPED THEREWITH
To prevent the normal operation of a clutch mechanism from being impaired.SOLUTION: A crushed stone pile forming attachment includes a cylindrical portion in which a crushed stone input hole is formed, a shaft rotatably disposed within the cylindrical portion, and a clutch mechanism that transmits driving force from the shaft to the cylindrical portion. The clutch mechanism includes a first engagement member 52 fixed to one of the cylindrical portion and the shaft, and a second engagement member 54 rotatably supported to the other of the cylindrical portion and the shaft. When the shaft rotates in the normal rotation direction, the first engagement member and the second engagement member abut and engage, and transmit the rotation of the shaft to the cylindrical portion. When the shaft rotates in the reverse direction, the second engagement member rides over the first engagement member, and the rotation of the shaft is not transmitted to the cylindrical portion.SELECTED DRAWING: Figure 6
【課題】 クラッチ機構の正常な作動が損なわれることを抑制する。【解決手段】 砕石杭形成用アタッチメントは、砕石投入孔が形成される円筒部と、円筒部内に回転可能に配置されるシャフトと、シャフトから円筒部に駆動力を伝達するクラッチ機構を備えている。クラッチ機構は、円筒部とシャフトの一方に固定された第１係合部材５２と、円筒部とシャフトの他方に回動可能に支持された第２係合部材５４を備える。シャフトが正転方向に回転するときは、第１係合部材と第２係合部材が当接して係合し、シャフトの回転を円筒部に伝達する。シャフトが反転方向に回転するときは、第２係合部材が第１係合部材を乗り越え、シャフトの回転が円筒部に伝達されない。【選択図】図６
