Hydraulic energy, then hydraulic energy is converted into mechanical energy, it is necessary to the complex partses such as hydraulic oil pipeline, pump, valve, motor；Gear drive
Formula is not simple gear transmission structure, using final driving bit after multiple spur gears and bevel gear multistage transmission；Chain
Wheel driven type is also that stage-geared adds chain gear transmission；Solid flexible axle transmission is driven by quill shaft bevel gear, gear drive
Dynamic drill bit transmission；If gear, sprocket wheel be exposed to mud in, cause agitation mud power loss, if seal, it is necessary to
Rotary dynamic seal is done, complicated, fault rate is high, hardly possible maintenance.This all brings inconvenience for the use of people.

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-2, a kind of bit of rotary well bore sidewall core taker and push away core apparatus, including motor 1, gear dress
Put 4, flexible hollow shaft 7, drill bit device 8 and push away core apparatus, the core apparatus that pushes away includes pushing away core cylinder 2 and pushes away core piston rod 3, motor 1
It is connected with geared system 4, hollow shaft 5 is installed on geared system 4 and hollow shaft 5 is extended outside geared system 4, pushes away core work
One end of stopper rod 3 is arranged on and pushed away in core cylinder 2, and the other end for pushing away core piston rod 3 is suspended in hollow shaft 5, one end of flexible hollow shaft 7
It is connected with drill bit device 8, the other end and the shaft coupling 6 of flexible hollow shaft 7 are fixed, the slip cap of shaft coupling 6 is mounted in the outside of hollow shaft 5 simultaneously
And flexible hollow shaft 7 is slid axially relative to hollow shaft 5.Rotation-preventing mechanism is provided between shaft coupling 6 and hollow shaft 5.
The bit of the rotary well bore sidewall core taker and the workflow for pushing away core apparatus, are comprised the following steps that：
Step one, during core-drilling, core cylinder is pushed away and drives to push away core piston rod and be recovered to pushing away in core cylinder, motor driven gear device
Rotate, geared system drives hollow shaft rotation, due to clutch slips be sleeved in hollow shaft and shaft coupling and hollow shaft it
Between be provided with rotation-preventing mechanism, the rotation of hollow shaft passes to flexible hollow shaft, further passes to the drill bit on drill bit device, drill through
