Detailed description of the invention
Such as Fig. 1, shown in 10, it includes drill bit drilling rod, fixing bar set, first planet support plate, jumping through rings supports, bar, internal gear, planetary gear, planetary gear axle, the second planet support plate, jumping through rings spring bearing in head, drilling head, jumping through rings, centre drill dish, fluid torque-converter, drill bit is cut in jumping through rings side, the most as shown in Figure 3, fluid torque-converter input is connected with drill bit drilling rod, fluid torque-converter outfan is connected with bar in drill bit, bar one end in drill bit it is arranged on the upside of centre drill dish, as shown in Figure 3,4, on the downside of centre drill dish, multiple drilling head is installed；As it is shown in fig. 7, fixing bar set is nested in outside drill bit drilling rod, first planet support plate is arranged on fixing bar set lower end, and three planetary gears are uniformly mounted on the downside of first planet support plate by respective planetary gear axle circumference；As shown in Figure 8,9, the second planet support plate is arranged on the downside of three planetary gear axles, and symmetrical along center planetary gear face with first planet gear support plate；As shown in Figure 10, fixing on the downside of the shell body of fluid torque-converter and the second planet support plate connect；Internal gear is installed jumping through rings and is supported the inner side of upper end, three planetary gears engage with internal gear, jumping through rings is supported and is arranged on the shell of fluid torque-converter by jumping through rings spring bearing, as shown in Figure 5,6, jumping through rings is arranged on jumping through rings and supports lower end, multiple jumping through rings sides are cut head circumference and are uniformly arranged on jumping through rings lateral surface, are provided with multiple drilling head on the downside of jumping through rings；As shown in Figure 10, drill bit drilling rod has flute profile, drill bit drilling rod and three planetary gears at three planetary gear installed positions all to engage.
Such as Fig. 2, shown in 10, in the present invention, on drill bit, the drilling head of fractured rock is divided into two parts, brill dish centered by core, and Outboard Sections is jumping through rings；Jumping through rings is directly engaged with drill bit drilling rod by planetary gear, and jumping through rings is under the drive of internal gear, and rotating speed is contrary with drill bit rod rotation speed, and rotating speed is less than drill bit rod rotation speed；Centre drill dish is connected with drill bit drilling rod by fluid torque-converter; during central turnplate and rock collide; fluid torque-converter can regulate centre drill dish rotating speed and moment of torsion according to rock to the resistance of centre drill dish; and then the drilling head on protection centre drill dish avoids destroying; and by increasing moment of torsion, harder rock can be crushed, add the range of drill bit.The combination of the drilling head that inside and outside two-layer rotating speed is contrary can also add the damage capability to rock by rock is produced contrary shearing force；Additionally installing jumping through rings side outside jumping through rings and cut head, it is prevented from the borehole wall in the face of the abrasion of drill bit sidewall.The drill bit of the present invention needs to combine rock adsorption plant such as flushing type sucking pump and uses, it is therefore an objective to discharged from down-hole by the rock after broken.Fix bar set in the present invention, first planet support plate, planetary gear axle, the second planet support plate, fluid torque-converter shell are fixture, do not rotate with drill bit drilling rod.When certain drilling equipment installs the drill bit in the present invention, in addition to drill string being provided and drives drill bit drilling rod, it is also required to provide fixing end to install fixing bar set.
Such as Fig. 1, shown in 10, on the downside of above-mentioned first planet support plate, it is also equipped with sealing ring.The design of sealing ring prevents crushed rocks to enter in planetary gear and destroys gear engagement.
Above-mentioned planetary gear number can be any one in 2,3,4,5.On the premise of space allows, the resistance that planetary number its jumping through rings the most can bear is the biggest.
As shown in Figure 2,6, on the downside of above-mentioned jumping through rings, circumference uniformly has multiple jumping through rings kerve and jumping through rings kerve installation site is cut between an installation site in jumping through rings side.Being also equipped with jumping through rings kerve bottom jumping through rings, drill bit rock after broken can be played and guide the effect discharged by it.
Above-mentioned fixing bar set is fixed on drilling equipment and does not rotates with drill bit drilling rod.
In sum, in the present invention, drill bit drilling rod is connected with centre drill dish by fluid torque-converter, and the drilling head of centre drill dish is with rock collision process, and fluid torque-converter can regulate moment of torsion and the rotating speed of brill dish, extends the life-span of drill bit and improves the efficiency of drilling well；Jumping through rings drilling head is additionally installed outside centre drill dish, planetary gear on internal gear that jumping through rings is supported by jumping through rings, first planet support plate engages with drill bit drilling rod, rotate with the contrary speed relatively low relative to drill bit drilling rod, jumping through rings drilling head is combined by such design with centre drill dish drilling head internal layer outer layer, the most contrary tangential velocity improves the crushing efficiency of rock, has preferable practical function.
