Abstract
The invention relates to a clay drill bit of a submersible drilling rig; the upper end of a submersible motor is connected with a drill rod by a drill rod connector, and the middle of the lower end of the submersible motor is connected with a drill bit by a drill bit connector; the drill bit comprises a lower drill rod and two drill bit inclined plates arranged at the lower end of the lower drill rod; the lower part of each drill bit inclined plate is evenly provided with a plurality of spike teeth; the clay drill bit is characterized in that the left side and the right ride of the lower end of the submersible motor are respectively provided with a fixed wing; each fixed wing is provided with a vertical rod; the lower end of each vertical rod is connected with the inclined plate; and the two fixed wings are respectively connected and fixed at the two sides of the lower end of a shell of the submersible motor by the vertical rods. When the clay drill bit is in work, relative motion is formed between the drill bit and the fixed wings, and clay can be smashed by stirring, so that the clay drill bit is capable of rapidly drilling in stiff clay.
Description
One, technical field
The present invention relates to a kind of diving drill machine drill bit, particularly a kind of diving drill machine clay drill bit that can in stiff clay, creep into.
Two, background technology:
At present, when creeping in stiff clay, common diving drill machine rotates with drill bit, so driving speed is very slow or can not tunnel because clay is bonded on the drill bit.
Three, summary of the invention:
The present invention has remedied the shortcoming of above diving drill machine, and a kind of clay drill bit that can in stiff clay, creep into fast is provided.
The present invention realizes through following technical scheme:
A kind of diving drill machine clay drill bit; The submersible motor upper end is connected in drilling rod through drilling rod; Be connected in drill bit through drill bit in the middle of the submersible motor lower end, drill bit comprises drilling rod and the two drill bit swash plates in drilling rod lower end down down, and drill bit swash plate bottom is distributed in several spike-tooths; Its special character is: submersible motor lower end the right and left is respectively equipped with a fixed-wing; Each fixed-wing is provided with a vertical rod, and the vertical rod lower end is connected in swash plate, and two fixed-wings are connected and fixed on both sides, submersible motor shell lower end through vertical rod respectively.
The present invention has following characteristics:
The present invention is drill bit and fixed-wing formation relative motion when work, and clay is blended, and can in stiff clay, creep into fast.
Four, description of drawings:
Below in conjunction with accompanying drawing the present invention is further described:
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, drilling rod, 2, drilling rod connects, 3, submersible motor, 4, drill bit connects, 5, vertical rod connects, 6, vertical rod, 7, wing plate, 8, the drill bit swash plate, 9, spike-tooth, 10, drilling rod down.
Five, the specific embodiment:
Accompanying drawing is a kind of specific embodiment of the present invention; These embodiment submersible motor 3 upper ends connect 2 through drilling rod and are connected in drilling rod 1; Connect 4 through drill bit in the middle of submersible motor 3 lower ends and be connected in drill bit, drill bit comprises drilling rod 10 and the two drill bit swash plates 8 in drilling rod lower end down down, and drill bit swash plate bottom is distributed in several spike-tooths 9; Its special character is: submersible motor 3 lower end the right and lefts are respectively equipped with a fixed-wing; Each fixed-wing is provided with a vertical rod 6, and the vertical rod lower end is connected in 7, two fixed-wings of swash plate and is fixed in both sides, submersible motor shell lower end through vertical rod connection 5 respectively.
Submersible motor drove drill bit and rotates when the present invention worked, and did not rotate with drill bit because fixed-wing is fixed on the submersible motor shell, so, just forms drill bit and fixed-wing relative motion and clay is blended, with outside the drill-in fluid overfolw hole and pore-forming.
Claims (2)
