The invention discloses a novel hydraulic excavator piling device. The novel hydraulic excavator piling device structurally comprises an external connecting frame, a fixing screw and a piling mechanism; the fixing screw is connected to an internal thread of the external connecting frame, and the piling mechanism penetrates through the internal position of the external connecting frame; when a lower pressure rod descends, reverse thrust is generated by the bottom of a soil pile pit on two outer expansion plates, and the external expansion plates can slide and unfold outwards along a connecting frame so that the sides of the external expansion plates can compact the inner wall of the soil pile pit, thus the phenomenon that soil on the inner wall of the soil pile pit falls off when a lower pressing rod is completely pulled out is avoided, and the situation that soil on the inner wall of the soil pile pit containing much sand is prone to falling off is effectively avoided; and the inner wall of the soil pile pit extrudes the position between two sliding plates, the sliding plates can slide towards the two sides along a rear frame, therefore the sliding plates can flatten and compact the inner wall of the soil pile pit, and therefore, the lower pressing rod can be easily pulled out of the interior of the soil pile pit.
本发明公开了一种新型液压挖掘机打桩装置，其结构包括外接框、固定螺丝、打桩机构，固定螺丝与外接框的内部螺纹连接，打桩机构贯穿于外接框的内部位置，通过土桩坑的底部在下压杆下降时对两个外扩板产生的反推力，能够使外扩板沿着衔接架向外进行滑动展开，从而使外扩板的边侧能够对土桩坑的内壁进行压实，从而使下压杆被完全被拉出时土桩坑内壁的泥土不会出现掉落的现象，有效的避免了含有沙子较多的土桩坑内壁的泥土容易出现掉落的情况，通过土桩坑的内壁对两个滑动板之间产生的挤压，能够使滑动板沿着后置框向两侧滑动，从而使滑动板能够对土桩坑的内壁进行抹平压实，从而使下压杆能够轻松抽离土桩坑的内部。
