Single-shaft multi-directional stirring cement mixing pile drill bit
The invention discloses a single-shaft multi-directional stirring cement mixing pile drill bit. The single-shaft multi-directional stirring cement mixing pile drill bit comprises a first sleeve rod, a forward stirring blade, a second sleeve rod, a drill bit body, a hollow main shaft, a planet wheel, a planet wheel support, a reverse stirring blade, a first bevel gear, a second bevel gear and a third bevel gear. The first sleeve rod is connected with a drill rod of a cement mixing pile machine, and the hollow main shaft fixedly communicates with a cement paste connector. The drill rod of the cement mixing pile machine drives the first sleeve rod to rotate, the first sleeve rod drives the second sleeve rod through a planet wheel system structure between the first sleeve rod and the second sleeve rod, the rotating speed of the second sleeve rod is higher than that of the first sleeve rod, the rotating direction of the second sleeve rod is opposite to that of the first sleeve rod, a relative negative pressure area is formed below the forward stirring blade, and the risk of backflow of cement paste can be reduced. The reverse stirring blade rotates while revolving around the hollow main shaft, in other words, the single-shaft multi-directional stirring cement mixing pile drill bit can cut off the backflow path of the cement paste in the vertical direction, and the quality of a formed cement mixing pile can be improved.
本发明公开了一种单轴多向搅拌的水泥搅拌桩钻头，包括：第一套杆、正向搅拌叶、第二套杆、钻头、空心主轴、行星轮、行星轮支架、反向搅拌叶、第一锥形齿轮、第二锥形齿轮和第三锥形齿轮。第一套杆与水泥搅拌桩机的钻杆相联，空心主轴与水泥浆接口固定连通。水泥搅拌桩机的钻杆带动第一套杆转动，第一套杆通过第一套杆和第二套杆之间的行星轮系结构对第二套杆进行传动，第二套杆的转速高于第一套杆，且转向相反，正向搅拌叶的下方形成有一个相对负压区，有利于减小水泥浆的倒流的风险。反向搅拌叶在绕空心主轴公转的同时进行自转，即单轴多向搅拌的水泥搅拌桩钻头可从竖直方向切断水泥浆倒流的路径，有利于提高成桩后水泥搅拌桩的质量。
