Double-wheel double-milling multi-stirring power head
The invention relates to a double-wheel double-milling multi-stirring power head, and belongs to the technical field of construction machinery equipment. A conical screw hole in the upper part of a lower-layer drill bit core pipe is screwed in a conical screw rod at the lower end of a middle-layer drill bit core pipe for quick fixed connection; the lower part of the lower-layer drill bit core pipeis fixedly connected with a drill bit tip; the lower-layer drill bit core pipe is fixedly connected with a lower-layer horizontal stirring fixed blade; a circular guniting hole is formed in the pipewall of the lower part of the lower-layer drill bit core pipe; an upper-layer drill bit core pipe, the middle-layer drill bit core pipe and the lower-layer drill bit core pipe are all hollow cylindrical rigid bodies, and are communicated with each other; and a circular guniting hole is formed in the pipe wall of the lower part of the lower-layer drill bit core pipe. The double-wheel double-millingmulti-stirring power head can realize the double-wheel double-milling multi-stirring effect by using a one-way drill rod, forms piles once without needing repeated stirring, effectively improves theuniformity and the strength of the stirring piles, improves the construction efficiency, and saves the construction cost.
本发明涉及一种双轮双铣多搅动力头，属建筑机械装备技术领域。本发明的下层钻头芯管上部锥螺孔与中层钻头芯管下端锥螺杆旋入快速固定连接,下层钻头芯管下部固定连接钻头尖，下层钻头芯管上固定连接下层水平搅拌固定叶片，下层钻头芯管下部管壁上开有圆形喷浆孔,上层钻头芯管、中层钻头芯管、下层钻头芯管皆是空心圆柱刚体且相互之间连通,下层钻头芯管下部管壁设置圆形喷浆孔。本发明利用单向钻杆即可实现双轮双铣多搅效果，并一次成桩，无需反复复搅，有效提高搅拌桩的均匀性及强度，提高了施工效率，节约了施工成本。
