Double-rotation drilling device and drilling method
The invention discloses a double-rotation drilling device and a drilling method. A double-rotation drilling device comprises a power head, a drill rod and a drill bit mechanism, the two ends of the drill rod are connected with the power head and the drill bit mechanism respectively, and the power head drives the drill bit mechanism to rotate through the drill rod. The drill bit mechanism comprises a stirring frame, a drill bit shaft, a stirring head and a drill bit; the stirring frame comprises an upper rotating seat, a lower rotating seat and at least two stirring arms; the drill rod comprises an inner rod and an outer rod; the drill is arranged at the lower end of the drill shaft. The drilling method comprises the steps that the power head drives the drill rod to rotate and drives the drill bit mechanism to rotate to dig holes in the ground; during hole digging, the drill bit rotates in the reverse direction to drill the bottom face, the stirring frame rotates in the forward direction, holes drilled by the drill bit are expanded through the first digging teeth, and the hole digging speed is high. The stirring frame and the stirring head are matched for stirring, so that stirring is faster and more uniform. The power head is compact in overall layout, small in size, simple in structure and convenient to maintain.
一种双旋转钻孔装置及钻孔方法；一种双旋转钻孔装置，包括动力头、钻杆和钻头机构，钻杆的两端分别连接动力头和钻头机构，动力头通过钻杆驱动钻头机构转动；钻头机构包括搅拌框、钻头轴、搅拌头、钻头；搅拌框包括上旋座、下旋座、至少两个搅拌臂；钻杆包括内杆和外杆；钻头设于钻头轴的下端。一种钻孔方法，包括动力头带动钻杆转动，驱动钻头机构旋转对地面进行挖孔；本发明挖孔时，钻头反向旋转对底面进行钻孔，搅拌框正向旋转，通过第一挖齿对钻头钻的孔进行扩孔，挖孔速度快。搅拌框与搅拌头配合搅拌，搅拌更快更均匀。动力头整体布局紧凑，体积小，结构简单，维修方便。
