The invention relates to the technical field of excavators, in particular to an excavator hydraulic accessory log grapple which comprises a connecting body and an oil cylinder, two large grabs and two small grabs are symmetrically and rotationally connected to the lower side of the connecting body in parallel, an oil cylinder rear cover and an oil cylinder front sleeve are arranged on the two sides of the oil cylinder respectively, and a two-way balance valve is connected to one side of the oil cylinder in a buckled mode. An oil cylinder protection plate is connected to the position, opposite to the two-way balance valve, of one side of the large claw and the small claw through bolts, an oil cylinder valve block, a valve element and an oil pipe connector are convenient to replace and protected against collision damage, and the continuous operation time of the log grabber is prolonged.
本发明涉及挖掘机技术领域，尤其是一种挖掘机液压属具抓木器，包括连接体、油缸，连接体的下侧平行对称转动连接设有两个大小抓，油缸的两侧分别设有油缸后盖、油缸前套，油缸的一侧卡扣连接设有双向平衡阀，大小抓的一侧且与双向平衡阀相对的位置通过螺栓连接设有油缸护板，便于更换油缸阀块、阀芯及油管接头，又保护其不被碰伤，提高抓木器连续作业时间。
