ATTACHMENT DETACHABLE MECHANISM AND WORK MACHINE
To ensure stable and good workability while a work attachment can be freely attached and detached.SOLUTION: In an attachment detachable mechanism 140, a work attachment 150 is provided with two pairs of support holes 152 and 154 that are separated from each other in the swinging direction of the work attachment and that make a pair in the axial direction O perpendicular to the swinging direction. In tip portions 132A and 136B (connecting portions of an arm body 127) disposed between the two pairs of support holes 152 and 154, pin expansion and contraction mechanisms 140A and 140B including two pairs of pins 142A and 142B that are separated and approached in the axial direction O and linear motion mechanisms 144A and 144B that support the two pairs of pins 142A and 142B are incorporated. When the pin expansion and contraction mechanisms 140A and 140B drive the two pairs of pins 142A and 142B away from each other, the pins 142A and 142B are inserted into the support holes 152 and 154, respectively.SELECTED DRAWING: Figure 2
【課題】作業アタッチメントの脱着が自在でありながら、安定して良好な作業性が確保可能となる。【解決手段】アタッチメント脱着機構１４０において、作業アタッチメント１５０には、自身の揺動方向に互いに離間し、且つ揺動方向とは直交する軸方向Ｏにおいてそれぞれ対をなす２対の支持孔１５２、１５４が設けられ、２対の支持孔１５２、１５４の間に配置される先端部１３２Ａ、１３６Ｂ（アーム体１２７の連結部分）には、軸方向Ｏで離間接近する２対のピン１４２Ａ、１４２Ｂと、２対のピン１４２Ａ、１４２Ｂを支持する直動機構１４４Ａ、１４４Ｂと、を備えるピン伸縮機構１４０Ａ、１４０Ｂが内蔵され、ピン伸縮機構１４０Ａ、１４０Ｂが２対のピン１４２Ａ、１４２Ｂを互いに離間駆動させた際には、支持孔１５２、１５４にピン１４２Ａ、１４２Ｂがそれぞれ挿入される。【選択図】図２
