Uplink synchronization in mouth 513 and the first notch of interior drill bit 311, meanwhile, motor column cap 83 is in outer motor third notch 523 and interior motor
First notch, 321 uplink synchronization.During this, 8 uplink synchronization of drill bit assembly 7 and electric machine assembly so that the brill of drill bit assembly 7
Head cutter 72 is gradually leant out, while away drill cuttings 72 rotate, and carry out punching sampling.When motor column cap 83 reaches outer motor
When the vertex 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：
Driving slide plate 5 continues to move right under outer power drive, and drill bit assembly 7 and electric machine assembly 8 return to the original of step 1
Then position constantly repeats this process, complete punching coring.
As shown in Figure 10, a planet right-angle reduction device 711 is equipped in drill bit assembly 7, the power of electric machine assembly 8 passes through motor
Magnetic connects head 82 passes to drill bit magnetic connects head 73, and drill bit magnetic connects head 73 is passed by planet right-angle reduction device 711, then by power
Transport to away drill cuttings 72.
The retarder drill bit of the present invention separates motor and retarder with motor magnetic coupling overturning feed mechanism, passes through
Magnetic coupling connects.If retarder internal balance oil reveal, external high pressure slurry compounding retarder, but not damage motor and
Control system.
In addition, the interior drill bit notch 31 and interior motor slot 32 of the present invention, and outer drill bit notch 51 and outer motor slot
52 can also use other structures, as long as the overturning of drill bit assembly 7 and the coupling of drill bit assembly 7 and electric machine assembly 8 can be realized
Close with detach and drill bit assembly 7 coupled with electric machine assembly 8 after uplink synchronization function.
In addition, the retarder drill bit of the present invention is also not necessarily limited to interior drill bit notch 31 with motor magnetic coupling overturning feed mechanism
With the notch arrangement of interior motor slot 32, and outer drill bit notch 51 and outer motor slot 52 etc, machinery can also be utilized even
Bar or mechanical gear drive mechanism or hydraulic drive structure etc., if can realize drill bit assembly 7 overturning and drill bit assembly 7 with
The coupling of electric machine assembly 8 with detach and drill bit assembly 7 coupled with electric machine assembly 8 after uplink synchronization function.
Not limited to this, any change or replacement expected without creative work should all cover the guarantor in the present invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
