The technical problem to be solved is to provide a drill bit of the welldrilling mounted with a self-excitation type pulse resonance jet nozzle which can improve the drilling speed. The technical project for solving the technical problem includes a drill bit and a nozzle which contains an inlet nozzle and a reflector; the inner hole of the inlet nozzle is divided to three sections, the inner hole upper section is an inlet, the inner diameter of the middle section is smaller, the lower section is an outlet, a lower reflecting surface is formed between the lower end of the outlet and the upper end of the middle reflecting surface; the inlet nozzle is mounted in the inner hole upper section of the reflector. The nozzle is mounted in the mounting hole of the drill bit nozzle. The invention is applied to the drill bit of the welldrilling. The beneficial effects are that, the nozzle can produce jet with large intensity to convert the fluid flow in the well bottom to ultrasonic instantaneous pulse flow, and grind bore meal in the well bottom repeatly, so as to improve speed of carrying out the bore meal, thereby improving drilling footage speed.

Background technology
The prior art drilling bit, in drilling process, the nozzle on the drill bit sprays mud simultaneously, in order to wash away the fractured rock in shaft bottom, guarantees to creep into carrying out smoothly of operation.Its weak point is that the insufficient strength of nozzle ejection mud flush rock is big, has influenced the raising of rate of penetration.
Summary of the invention
Technical problem to be solved provides a kind of drilling bit that rate of penetration has auto-excitation type pulse resonance jet nozzle that improves.
The technical scheme that solves its technical problem is as follows: the drilling bit of auto-excitation type pulse resonance jet nozzle is housed, comprises drill bit and auto-excitation type pulse resonance jet nozzle;
Auto-excitation type pulse resonance jet nozzle comprises import mouth and reflector; The endoporus of import mouth is divided into three sections, endoporus stage casing internal diameter is less, the import of endoporus epimere is the hole that its up big and down small cross section edge is a circular arc, the bottom diameter in hole equals endoporus stage casing internal diameter, the endoporus hypomere is up-small and down-big round taper hole, the upper-end inner diameter of round taper hole equals endoporus stage casing internal diameter, and the surface of round taper hole is last reflecting surface; The endoporus of reflector is divided into three sections, the internal diameter of endoporus epimere equals the external diameter of import mouth, the upper-end inner diameter in endoporus stage casing equals the bottom diameter of the endoporus hypomere of import mouth, the endoporus stage casing can be the cylinder-shaped hole that equates of internal diameter up and down, it also can be the up big and down small turbination hole of internal diameter, the surface in endoporus stage casing is middle reflecting surface, the internal diameter of endoporus hypomere is less than the internal diameter of endoporus epimere, be outlet, the lower end of reflecting surface during the upper end of outlet is higher than forms reflecting surface down between the lower end of middle reflecting surface and the upper end of outlet; The import mouth is loaded in the endoporus epimere of reflector with its hypomere.
The external surface of reflector can be made as two sections, and the epimere diameter is bigger, and the hypomere diameter is less.Auto-excitation type pulse resonance jet nozzle is packed in the nozzle installing hole on the drill bit, on the nozzle installing hole with auto-excitation type pulse resonance jet, there is a circle collar groove appearance epimere of the reflector on the nozzle and the corresponding position of the boundary between the hypomere, behind the auto-excitation type pulse resonance jet nozzle of packing into, the spring collar of packing in the collar groove is with auto-excitation type pulse resonance jet nozzle card jail.
Also can in the drill bit nozzle installing hole, make internal thread, at the appearance epimere making of reflector and the corresponding external screw thread of internal thread on the nozzle installing hole, during the auto-excitation type of packing into pulse resonance jet nozzle, with the dress jail in the internal thread of nozzle installing hole of packing into of the external screw thread on the reflector.
Beneficial effect: the present invention is applied to drilling bit.Beneficial effect is that auto-excitation type pulse resonance jet nozzle is because self self-priming effect can produce the very big jet of intensity, make the liquid circulation in shaft bottom turn to ultrasonic transient pulse stream, to grind the shaft bottom landwaste repeatedly, improve the speed of taking away landwaste, thereby improve drill footage speed.
