Uplink synchronization in mouth 513 and the first notch of interior drill bit 311, meanwhile, motor stigma 83 is in the notch 523 of outer motor the 3rd and interior motor
The uplink synchronization of first notch 321.During this, drill bit assembly 7 and the uplink synchronization of electric machine assembly 8 so that the brill of drill bit assembly 7
Head cutter 72 gradually leans out, while away drill cuttings 72 are rotated, carries out punching sampling.When motor stigma 83 reaches outer motor
During the summit of three notches 523 and the first notch of interior motor 321, away drill cuttings 72 do not continue to lean out, and drilling terminates.
Step 6：
Slide plate 5 is driven to continue to move right under external force driving, drill bit assembly 7 and electric machine assembly 8 return to the original of step 1
Position, then, constantly repeats this process, completes coring of punching.
As shown in Figure 10, a planet right-angle reduction device 711 is provided with drill bit assembly 7, the power of electric machine assembly 8 passes through motor
Magnetic connects 82 pass to drill bit magnetic connects 73, and drill bit magnetic connects 73 are by planet right-angle reduction device 711, then power is passed
Transport to away drill cuttings 72.
Decelerator drill bit of the present utility model separates motor with decelerator with motor magnetic coupling upset feed mechanism,
Connected by magnetic coupling.If decelerator internal balance oil is revealed, external high pressure slurry compounding decelerator, but will not be damaged electronic
Machine and control system.
