Technical problem to be solved in the utility model is to provide a kind of drilling well drill bit and improves drilling efficiency, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the technical scheme that this utility model offer is following: a kind of drilling well drill bit, including drill body, described drill bit includes female drill bit and sub-drill bit, female drill bit is the cavity structure that bottom is uncovered, sub-drill bit is arranged in cavity, Mobile base it is additionally provided with in cavity, it is provided with electric expansion bar between bottom and the Mobile base of cavity, electric rotating machine it is provided with in Mobile base, sub-drill bit is connected with the outfan of electric rotating machine, the end of sub-drill bit is additionally provided with drill, drill is obliquely installed relative to sub-drill axis, accumulator it is provided with in Mobile base, sub-drill bit activate switch and telescoping switch, accumulator, sub-drill bit activate switch and electric rotating machine composition series circuit, accumulator, electric expansion bar and telescoping switch composition series circuit.
Preferably, described sub-drill bit activate switch and telescoping switch are remote wireless control switch.
Preferably, described drill is made up of diamond.
Preferably, described cavity inner wall is wound with chute, and the lateral wall of Mobile base is provided with slide block, and slide block is stuck in chute.
Preferably, it is socketed with compression spring outside described electric expansion bar.
Above technical scheme is used to provide the benefit that: the drilling well drill bit of this utility model structure, at female bit, while drilling well, promoter drill bit, sub-drill bit stretches back and forth, simultaneously under the effect of compression spring, impacting ground, sub-drill bit also carries out drillng operation to ground, and its end is provided with drill, substantially increase drilling duty, improve drilling efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, mother's 1--drill bit, 2--drill bit, 3--cavity, 4--Mobile base, 5--electric expansion bar, 6--electric rotating machine, 7--accumulator, 8--drill, 9--chute, 10--slide block, 11--compression spring.
Detailed description of the invention
Describe preferred implementation of the present utility model below in conjunction with the accompanying drawings in detail.
Fig. 1 shows detailed description of the invention of the present utility model: a kind of drilling well drill bit, including drill body, described drill bit includes female drill bit 1 and sub-drill bit 2, female drill bit 1 is cavity 3 structure that bottom is uncovered, sub-drill bit 2 is arranged in cavity 3, Mobile base 4 it is additionally provided with in cavity 3, it is provided with electric expansion bar 5 between bottom and the Mobile base 4 of cavity 3, electric rotating machine 6 it is provided with in Mobile base 4, sub-drill bit 2 is connected with the outfan of electric rotating machine 6, the end of sub-drill bit 2 is additionally provided with drill 8, drill 8 is obliquely installed relative to sub-drill bit 2 axis, accumulator 7 it is provided with in Mobile base 4, sub-drill bit 2 activate switch and telescoping switch, accumulator 7, sub-drill bit 2 activate switch and electric rotating machine 6 form series circuit, accumulator 7, electric expansion bar 5 and telescoping switch composition series circuit.
Sub-drill bit activate switch and telescoping switch are remote wireless control switch.
Radio remote control switch is divided by the carrier of transmission control instruction signal and can be divided into for wireless remotecontrol, ultra-sonic remote control, infra-red remote control, can be divided into by the coded system difference of signal: frequency coding and pulse code, can be divided into by transmission channel number: multi-channel remote and single channel, the number of instructions difference can transmitted by the same time can be divided into: single channel and Multi-way remote control, can be divided into the control technology of controlled object by command signal: switching mode proportional-type remote control.
Wireless control switch is to be combined by emitter and receptor, and emitter is by encoded for the control button of effector, and modulation carries out launching wireless signal in radiofrequency signal, it is also possible to be said to be an encoder.And receptor is that the wireless signal received carries out encoding signal further decoding, obtain the signal corresponding with controlling button, then go to control the work of corresponding circuit, also referred to as decoder.
Emitting portion i.e. remote controller and transmitter module, remote controller is independently to use as a complete machine, externally lead to wiring pile crown, remote control module is taken as an element to use, receiving portion i.e. superhet and superregenrative reception mode, its regenerative detection circuit of being actually operated under intermittent oscillation state of superregenerative demodulator circuit.
Drill is made up of diamond.Diamond is material the hardest during find on earth at present numerous naturally occur, and is used for making drill, greatly reduces the wear intensity of drill, improves the service life of drill.
Cavity 3 inwall is wound with chute 9, and the lateral wall of Mobile base 4 is provided with slide block 8, and slide block 8 is stuck in chute 9, and under the effect of electric expansion bar, sub-drill bit, during flexible, itself rotates, and promotes the efficiency of drilling well further.
It is socketed with compression spring 11 outside electric expansion bar 5, coordinates the work of electric expansion bar, ground is caused bigger impulsive force, improve drilling efficiency.
The drilling well drill bit of this utility model structure, at female bit, while drilling well, promoter drill bit, sub-drill bit stretches back and forth, simultaneously under the effect of compression spring, impacting ground, sub-drill bit also carries out drillng operation to ground, and its end is provided with drill, substantially increase drilling duty, improve drilling efficiency.
Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
