In the device, the high-pressure air pipe and the high-pressure water pipe are arranged on the two sides of the drill rod respectively, the height of the high-pressure air pipe is reasonably equipped, the high-pressure water pipe and the high-pressure air pipe are matched for use, and through adopting the principle of communicating vessels, slurry containing big rocks at the bottom hole can be quickly discharged, the problem of repeated underground crush can be alleviated, the service life of a cutter on the drill bit can be prolonged, the drilling efficiency can be improved, the slurry condition can be especially improved, and big rocks and the like can be discharged from the underground to the ground through the drill rod under high pressure.
Description
Technical field
The utility model belongs to the shaft drilling machine technical field, especially a kind of pressure plasma discharge technology of unit head rig.
Background technology
Slurry-discharging equipment is the vitals of shaft drilling machine, and the mud in the unit head borer drilling procedure all is discharged to the face of land through slurry-discharging equipment at the bottom of ground, adopts slurry-discharging equipment in the past, tends to bring the repetition of ground bed rock stone etc. broken, causes unnecessary waste.
The utility model content
The purpose of the utility model is the deficiency for solving the problems of the technologies described above; A kind of slurry-discharging equipment of unit head rig is provided, can gets rid of the mud that large rock mass is contained in the down-hole fast, alleviated the down-hole and repeated broken; Prolong the application life that drill bit is fixed a cutting tool, improved drilling efficiency.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: a kind of slurry-discharging equipment of unit head rig, comprise drill bit and drilling rod, and drill bit is arranged on the lower end of drilling rod; Described drilling rod has cavity structure; Be respectively equipped with high-pressure air hose and high-pressure water pipe in the both sides of drilling rod, an end of high-pressure air hose is connected with outside air line, and the other end of high-pressure air hose is provided with air outlet; The outer wall that air outlet passes drilling rod is connected with the cavity of drilling rod, and the water side of high-pressure water pipe is arranged on the drilling rod bottom.
The length of high-pressure air hose is less than the length of drilling rod.
The beneficial effect of the utility model is:
The utility model is through being provided with high-pressure air hose and high-pressure water pipe respectively in the drilling rod both sides, and the height of reasonable disposition high-pressure air hose is used through high-pressure water pipe and high-pressure air hose; According to law of connected vessels, can get rid of the mud that the shaft bottom contains large rock mass fast, alleviated the down-hole and repeated broken; Prolonged the application life that drill bit is fixed a cutting tool; Improved drilling efficiency, especially improved the plasma discharge situation, can make large rock mass etc. at the bottom of ground, be discharged to the face of land through drilling rod through suppressing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark among the figure: 1, drill bit, 2, drilling rod, 3, high-pressure water pipe, 4, high-pressure air hose, 5, air outlet, 6, mud in the drilling rod, 7, mud in the well.
The specific embodiment
As shown in the figure, a kind of slurry-discharging equipment of unit head rig comprises drill bit 1 and drilling rod 2; Wherein drill bit 1 is connected the lower end of drilling rod 2 through bolt; Described drilling rod 2 has cavity structure, that is to say that drilling rod 2 has hollow structure, is respectively equipped with high-pressure water pipe 3 and high-pressure air hose 4 in the both sides of drilling rod 2; The length of the length of high-pressure water pipe 3 and drilling rod 2 quite gets final product; High-pressure water pipe best one is through to the drill bit place, and the both sides that the water side of high-pressure water pipe 3 can be arranged on drill bit are used to wash out the rock piece on the borehole wall, and high-pressure water pipe 3 is connected with the delivery port of outside supply-water pump; Supply-water pump provides the water that has certain pressure to lead to the shaft bottom through high-pressure water pipe, and the current that have pressure remain in rock on the borehole wall after with the drill bit fragmentation and are flushed to that the shaft bottom is convenient discharges; The length of said high-pressure air hose 4 is less than the length of drilling rod 2, and an end of high-pressure air hose 4 is connected with outside air line, and the other end of high-pressure air hose 4 has air outlet 5; The outer wall that air outlet 5 passes drilling rod 2 is connected with the cavity of drilling rod, and in general, the air outlet 5 of high-pressure air hose 4 will be lower than the last plane of mud 7 in the well; That is to say that mud 6 will flood the air outlet 5 of high-pressure air hose in the drilling rod, the pressure that feeds high-pressure air hose 4 gases is confirmed according to actual conditions; The pressure that feeds gas in the reality is greater than the ambient value at air outlet 5 places; When air is sneaked in the drilling rod 2, mud 6 fully contacts with the high-pressure blast that high-pressure air hose 4 is got rid of in the drilling rod, and the density of sneaking into mud 6 in the drilling rod of high pressure draught this moment is less than the density of the interior mud 7 of well; Can know according to law of connected vessels: the density * ground surface liquid level of sneaking into mud 7 in the density * ground surface liquid level＜well of mud 6 in the drilling rod of pressure-air; Water under high pressure in the high-pressure water pipe 4 large rock mass that the shaft bottom is broken impacts the bit central place by force at this moment, and influence is under pressure; The mud that contains rock will be discharged through the cavity of drilling rod 2; This device has effectively stoped large rock mass broken in the repetition in shaft bottom, has improved drilling efficiency, has prolonged the life-span that drill bit is fixed a cutting tool.
