Coaxial bidirectional drill bit of stable roadbed mixing pile machine
The invention relates to roadbed stirring equipment, in particular to a coaxial bidirectional drill bit of a stable roadbed stirring pile machine. The coaxial bidirectional drill bit comprises a conical threaded mud breaker, an inner hollow transmission shaft is fixedly connected to the upper end of the conical threaded mud breaker, a first blade is fixedly mounted on the outer side of the lower end of the inner hollow transmission shaft, a driving gear is fixedly mounted on the outer side of the upper part of the inner hollow transmission shaft, the outer side of the lower portion of the inner hollow transmission shaft is movably sleeved with a positioning shaft sleeve, and a cross shaft gear is fixedly installed on the outer side of the upper end of the positioning shaft sleeve. The lower end of a driven gear is connected with the inner side of a box body, and a third blade is fixedly installed on the outer side of the box body, so that the box drives the blade to carry out rotary crushing in the direction opposite to the conical threaded mud breaker, and the effect of improving roadbed soil crushing efficiency and crushing quality is achieved; and meshing teeth on the outer sides of a driving gear, a transition gear and a driven gear are inclined spiral gear teeth, so that the meshing force, the wear resistance, the anti-seismic effect and the mute effect of bevel gears compared with straight teeth can be improved.
本发明涉及路基搅拌设备，具体为一种稳固路基搅拌桩机同轴双向钻头，包括锥形螺纹破泥器，锥形螺纹破泥器上端固定连接有内中空传动轴，内中空传动轴下端外侧固定安装有第一刀片，内中空传动轴上部外侧固定安装有驱动齿轮，内中空传动轴下部外侧活动套接有定位轴套，定位轴套上端外侧固定安装有齿轮十字轴，通过被动齿轮下端与箱体内侧相连接，且箱体外侧固定安装有第三刀片，因而能让箱体带动刀片进行与锥形螺纹破泥器相反方向的旋转破碎，达到提高路基土破碎效率与破碎质量的效果，其中通过驱动齿轮、过度齿轮、被动齿轮外侧咬合齿为倾斜的螺旋状轮齿设置，使得能提高锥齿轮之间相较直齿的咬合力、耐磨性、抗震效果与静音效果伤。
