The present invention provides a kind of shaft drilling machine, including main support 1, drilling rod 2, electric pulse drill bit 3 and drilling fluid cabinet 5.
Specifically, main support 1 primarily serves the effect of carrying, for setting and supports drill rods 2 etc., in use, main support 1
In construction ground.
It should be noted that the present invention to the concrete shape and structure of main support 1 without limitation, as long as main support can be made
1 has enough intensity, rigidity and stability.
Drilling rod 2 plays the role of fixing and supporting for electric pulse drill bit 3 to be arranged to electric pulse drill bit 3.Specifically, it bores
Bar 2 is arranged on main support 1, and drilling rod 2 and main support 1 are slidably cooperatively connected, in order to realize the drilling fortune of drilling rod 2
It is dynamic；Drilling rod 2 is vertically arranged, in order to bore vertical shaft.
Electric pulse drill bit 3 is set to the bottom end of drilling rod 2, shock wave, jet stream or plasma for generating by pulsed discharge
The mechanics effect in channel cracks rock until broken, and specifically, electric pulse drill bit 3 includes high-field electrode 31 and low tension
Pole 32, high-field electrode 31 and low-field electrode 32 are connected for corresponding with the positive and negative anodes of power supply 4.
It is understood that when high-field electrode 31 and low-field electrode 32 and power supply 4 are connected, it will be in high-field electrode 31
