68 start to rotate, and are collided to the place of original stuck trepan shell 66, after the purpose of crushed rock is played in collision, trepan
Shell 66 starts to bore 68 normally rotations with interior；When collision does not have crushed rock, trepan shell 66 continues stuck, then trepan shell 66
Reversely, positive collision, the rock to stuck trepan shell 66 repeatedly collide again later, and powder is hit until this goes out rock
After broken, interior brill 68 and trepan shell 66 restore normally to rotate.The present invention by trepan shell 66 and it is interior bore 68 power conversion pass to and
The forward and reverse rotation of trepan shell 66 carries out shock crushing to stuck rock, and the harder well of hardness can be bored with softer drill bit, and
And because motor 12 is always in power output, motor 12 will not be stuck and burn out.With preferable using effect.
The rotation of interior brill 68 of scroll spring 9 acting as originally provides certain torque, because interior bore what 68 rotations generated
Reaction torque is transmitted on support head cover 8 by scroll spring 9, and scroll spring 9 is built between motor 12 and machine shaft 16
Torque transmission has been stood, 12 direction of rotation of motor is on the one hand restored, on the other hand provides one by itself boil down to machine shaft 16
Fixed operation torque.
