The groove of uniform array, the transmission shaft are equipped with, circumferential evenly distributed limited block corresponding with groove, the limited block sliding
It is embedded in groove.
Further, the transmission shaft is two-layer cannula structure, and outer tube is connect with motor power, by motor power
It is transferred to and takes native knife, by way of being circumferentially sequentially connected, driving takes native swivel dynamic；Inner sleeve passes through outer tube, to vibrate liquid
The extension form of the piston rod of cylinder pressure is arranged in the outer tube of transmission shaft, and end is rotatablely connected with native knife is taken.To take soil
Knife does not influence its upper and lower high frequency and trembles while making rotating motion.
Further, it is provided with driving gear on the motor power output shaft, is fixedly installed on the transmission shaft
There is the driven gear engaged with driving gear.
The beneficial effects of the present invention are: the configuration of the present invention is simple, stable and reliable operation, digging operation is efficient, solves existing
Have in technology for frozen soil excavation complex steps, low efficiency, the high problem of equipment loss.Pass through vibrating hydraulic cylinder, motor and ring
Shape takes the ingenious gearing of native knife, and while so that circumgyration incision is excavated frozen soil, cutter high frequency trembles, and cutter is enable smoothly to move down
Cutting.
