Abstract

The utility model relates to a diamond compact piece indent drill bit, it has been solved the cascaded drill bit of current diamond compact piece indent and has has easily worn and torn, has collapsed the damage, takes place the technical problem of the sticking of tool easily, and it includes the body, and the upper end of body is equipped with three alar part cutting teeth, every alar part cutting teeth is connected with a ball -type diamond compact piece and at least one plane diamond compact piece, and ball -type diamond compact piece lies in the outside, and plane diamond compact piece lies in the inboard, and ball -type diamond compact piece and plane diamond compact piece use the horizontal plane to be the step distribution as the benchmark. The utility model discloses the wide application is taken out the discharge hole, is visited fields such as water hole, water injection hole and prospecting hole in the coal mine gas.

Description

Diamond compact indent drill bit
Technical field
The utility model relates to for gas discharge in mine hole, the rock crushing tool visiting water hole, water injection hole and field, geological prospecting hole, particularly relates to a kind of diamond compact indent drill bit.
Background technology
Existing diamond compact indent step bit is the welding of flat-face composite sheet, mainly there is following problem: 1, along with the increasing of drill bit diameter, workload near the outermost diamond compact of diameter increases, owing to diamond compact is arranged as staged in wing portion horizontal direction, when therefore creeping into, most outer wing is broken rock, and diamond compact is easy to wear, collapse damage; 2, existing drill bit is after creeping into end, carries and often occurs in drill-through journey the phenomenons such as bit freezing bringing inconvenience to the operation of workman, adds labour intensity and cost budgeting.
Summary of the invention
The utility model in order to solve existing diamond compact indent step bit easy to wear, collapse damage, easily there is the technical problem of bit freezing, it is provided that a kind of shock resistance is strong, good stability, long service life, carry the diamond compact indent drill bit boring no longer bit freezing.
The technical solution of the utility model is, comprises body, and the upper end of body is provided with three wing portions and cuts tooth; Each wing portion cuts tooth and is connected with a ball type diamond compact and at least one flat-face composite sheet, a ball type diamond compact is positioned at outermost, flat-face composite sheet is positioned at inner side, and ball type diamond compact and plane diamond compact take horizontal plane as benchmark is staged distribution.
Preferably, the quantity of flat-face composite sheet is two.
Preferably, the middle position of the upper end of body is provided with brokenly rock pillar, and broken rock pillar is connected with flat-face composite sheet.
Preferably, wing portion cuts and is connected with alloy gauge bar on tooth; The root that tooth is cut in wing portion is connected with reverse alloy cutting tooth.
Preferably, the upper end of body is also provided with cooling hole; The bottom of body is provided with connecting thread.
The beneficial effects of the utility model are, it is possible to bore into middle hard rock layer, it is achieved that a kind of shock resistance is strong, good stability, long service life, carry and boring not at the Novel polycrystalline diamond compact indent drill bit of bit freezing.
The feature that the utility model is further, by the description of following embodiment, is clearly recorded.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view.
Reference numeral illustrates:
1. ball type diamond compact, 2. flat-face composite sheet, 3. broken rock pillar, 4. cooling hole, 5. alloy gauge bar, 6. reverse alloy cutting tooth, 7. connecting thread, 8. body, 9. tooth is cut in wing portion.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As depicted in figs. 1 and 2, the bottom of body 8 is provided with connecting thread 7, and the middle position of the upper end of body 8 is provided with two broken rock pillars, 3, two broken rock pillars 3 and is welded with flat-face composite sheet 2 respectively.
The upper end of body 8 is provided with three wing portions with circumferential direction and cuts tooth 9. Each wing portion cutting tooth 9 is welded with a ball type diamond compact 1 and two flat-face composite sheet, 2, ball type diamond compact 1 is positioned at outermost, and two flat-face composite sheet 2 are positioned at inner side. A ball type diamond compact 1 and two flat-face composite sheet 2 take horizontal plane as benchmark is staged distribution, and that is a ball type diamond compact 1 is positioned at bottom. It should be noted that, the quantity of flat-face composite sheet 2 is not limited to two, it is possible to be one or more.
Each wing portion cuts and is connected with alloy gauge bar 5 on tooth 9. The root weld that tooth 9 is cut in each wing portion has reverse alloy cutting tooth 6.
The upper end of body 8 is also provided with cooling hole 4.
Owing to flat-face composite sheet 2 has good cutting ability, ensure that drilling efficiency, ball type diamond compact 1 has excellent shock resistance, owing to a ball type diamond compact 1 and two flat-face composite sheet 2 are arranged as staged in wing portion horizontal direction, when therefore creeping into, most outer wing cuts as broken rock, and ball type diamond compact 1 just can solve easy to wear, collapse the phenomenons such as damage.
The rock stratum of flat-face composite sheet 2 on broken rock pillar 3 to cut in indent circle, alloy gauge bar 5 is possible to prevent drill bit maximum diameter undergauge, reverse alloy cutting tooth 6 is the bit freezing phenomenon carried and bore to solve and often occur, there is rock stratum, top to come off when carrying brill and bit freezing easily occurs, and oppositely alloy cutting tooth 6 makes it to cut through, both avoided bit freezing to make hole wall round and smooth, bored under being of value to two times; The acting as composite sheet cooling, the washing away of hole wall, arrange powder of cooling hole 4; Connecting thread 7 is for being connected with drilling rod.
The above only to preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations. Every within the scope of scope of the present utility model, any amendment of making, equivalent replacement, improvement etc., all should within protection domain of the present utility model.
