With the pressure electromagnetism expansion link conllinear of only one of which revolute pair, and two revolute pairs can be had with drill bit drill rod axis
Pressure electromagnetism expansion link can be automatically adjusted to one suitably according to the stroke of two pressure electromagnetism expansion links
Position.After drill bit drilling rod and motor change into certain angle, can be simultaneously with identical stroke regulation pressure electromagnetism
Expansion link reaches to make the purpose of drill bit drilling well forward.Such being designed to is ensureing the same of drill bit drilling well forward
Time, it is allowed to drill bit has a certain degree with motor.Can be to the angle of drill bit drilling rod Yu machine shaft in the present invention
Control, for directed drilling.On the other hand, the first detent mechanism and the second detent mechanism make motor be at
Institute's drilled well bore center；Detent mechanism positions electromagnetism expansion link flexible can regulate the radial direction of arc plate away from
From, control the contact pressure of arc plate and well bore, and then limiting motor can be contacted by arc plate and well bore
Housing own rotation；On the other hand when the resistance that drill bit is applied by rock is excessive, for logical to the protection of drill bit
Overregulate arc plate makes arc plate and well bore that relative slip occurs, to offset the torsion that motor applies with the pressure of well bore
Square, can improve the intensity of well bore simultaneously；Motor is i.e. added on drill bit by the present invention with drill bit Integrated design
Independent energy supplying system, it is possible to increase drill bit general applicability in complex drilling job task, has higher
Practicality.
Relative to traditional drilling bit technology, in the present invention, drill bit drilling rod is connected with internal layer brill dish, drives internal layer
Brill dish rotates；Middle level jumping through rings and three middle levels support the revolving part that forms a whole and are referred to as media layer damage, and it passes through
Middle level the 3rd spring bearing is arranged on drill bit drilling rod, it is possible to rotate around drill bit drilling rod；Outer layer jumping through rings and two
Outer layer supports the revolving part that forms a whole and is referred to as layer structure, is arranged on middle level by outer layer the first spring bearing
3rd supports, it is possible to supports around middle level the 3rd and rotates.Drill bit drilling rod as sun gear, planet tooth is installed
The middle level of wheel collectively constitutes planet gear transmission as planet carrier, the outer layer that is provided with internal gear；Three-decker is constituted
Three speed drill bits, internal layer brill dish drilling speed is identical with drill bit drilling rod, and it is inevitable with same rotational speed rotation that drilling rod rotates endothecium structure
Turning, middle level and outer layer jumping through rings rotating speed are automatically adjusted rotating speed according to the rock resistance being each subject to, and can play protection
The purpose of drill bit；When the resistance that layer structure is subject to much larger than media layer damage by the resistance of rock, middle level is tied
Structure rotates, outer layer mechanism blockage, otherwise media layer damage is stuck, and layer structure rotates；When middle level and layer structure
The resistance being subject to is similar, then double-layer structure all can rotate with contrary direction of rotation；Double-layer structure at home and abroad
Rotation relationship is as easy as rolling off a log being alternately rotated of being formed in the short time, thus can more allow Lycopodium chinense Christ in being alternately rotated
Dynamic broken, add drill bit range.There is certain practical function.
Relative to traditional putting technique, in the present invention, electromagnetic unit is formed by coil winding conducting magnetic column, works as coil
After energising, conducting magnetic column both sides produce magnetic pole；Multiple electromagnetic units are connected, after being energized, each electromagnetic unit
Produce magnetic pole, when producing same pole between each electromagnetic unit, between electromagnetic unit, produce repulsion, spacing
Widen；When producing mutual different pole between each electromagnetic unit, attract each other between electromagnetic unit, hypotelorism.
Multiple electromagnetic units are put in design a variable space of the space length closed, and the present invention is led by non-
Use arcuate guide rail to be nested to form adjustable length space between bar and the outer bar of electromagnetism in the electromagnetism of magnetic material, and lead to
Stopper slot on the limited block crossed in electromagnetism on bar bar outer with electromagnetism coordinates interior the stretching between bar and outer bar of restriction
Contracting amount；Arcuate guide rail on bar and electromagnetism bar outward is mounted on face in electromagnetism conducting strip, and interior bar conduction
Connecting energising by inside and outside bar conducting strip between sheet and outer bar conducting strip, it is interior that foreign current connects in electromagnetism on bar
Bar conducting strip, when bar slides outside, conducts the current on outer bar conducting strip by inside and outside bar conducting strip, interior bar
Foreign current is imported to electromagnetism with outer bar conducting strip by contacting with the unit conducting strip of electromagnetic unit by conducting strip
In unit, the coil in each electromagnetic unit and conducting strip, power supply composition closed-loop path.The present invention passes through electromagnetism
Effect realizes the flexible of bar, energy-conserving and environment-protective, and does not substantially have easily worn part, has preferable practical function.
