Abstract
The utility model relates to a drill bit technical field, a diamond compact drill, including the threaded rod, the bit body of being connected with the threaded rod, the bit body center is equipped with the inlet opening, left wing's seat and right flank seat weld curved diamond compact's blade respectively, working face the place ahead of blade is equipped with the slag runner, the one side and the bit body of slag runner are connected with arc portion, grooving on this arc portion and the threaded rod is linked together, left wing's seat and right flank seat appearance are the circular arc, one side that left wing's seat and right flank seat are close to the slag runner is equipped with mutual parallel arrangement's grooving, the both sides grooving is equipped with the transition portion that is parallel to each other with the junction of slag runner. The utility model discloses optimized the position and the shape of slag runner, the wing seat improvement department grooving that will be located same circular arc is used for row sediment, advantages such as drilling speed is fast, row's sediment is effectual, reinforcing wearability, reduction resistance, increase moment of torsion, under equal rock condition, the 2 -3 before bit life is improving after improving doubly.
Description
Technical field
The utility model relates to bit technique field, is specifically related to a kind of diamond compact bit.
Background technology
Supporting is normally carried out by anchor pole in the tunnel in railway tunnel, colliery, and therefore, efficient, fast, the anchor bit of stable performance plays an important role, the quality of drill bit is directly connected to efficiency and the boring cost of boring.In order to increase work efficiency, ensure drilling quality, also more and more higher to the requirement of anchor bit.Diamond roof-bolt drilling head conventional at present, its diamond compact welded above and wing seat are circular arc on cross section, row's powder slowly and not thorough, easy bury drills, bit freezing in use procedure, the hole quality got out is low, causes impact resistance in use procedure low, wear no resistance, run into competent bed easily to occur collapsing limit problem, cause drill bit to lose efficacy, reduce drilling efficiency.
Summary of the invention
The utility model is slagged tap slowly to overcome, and the problem of easy bit freezing provides the diamond compact bit that a kind of rate of penetration is fast, deslagging is effective, abrasion resistance strengthens.
The utility model realizes by the following technical solutions, a kind of diamond compact bit, comprise threaded rod, the bit body be connected with threaded rod, bit body center is provided with inlet opening, bit body is provided with centrosymmetric left wing seat and right flank seat, left wing's seat and right flank seat are welded with the blade of the diamond compound of arc respectively, the work plane front of described blade is provided with ash pit, side and the bit body of ash pit are connected with curved portions, this curved portions is connected with the grooving on threaded rod, left wing's seat and right flank seat profile are circular arc, left wing's seat and right flank seat are provided with grooving arranged in parallel near the side of ash pit, the junction of both sides grooving and ash pit is provided with the transition part be parallel to each other.
Preferably, the angle of described grooving and horizontal axis is 25 ° ~ 35 °.
Preferably, the distance between described grooving is 24 ~ 28mm.
Preferably, the distance between described transition part is 20 ~ 25mm.
Usefulness of the present utility model is, optimizes position and the shape of ash pit, the wing seat improvement place grooving being positioned at same circular arc is used for deslagging, rate of penetration is fast, deslagging is effective, strengthens abrasion resistance, reduces resistance, increases the advantages such as moment of torsion; Under equal ROCK CONDITIONS, after improving, bit life is 2-3 times before improving.

1. wing seat, 2. bit bodys in figure, 21. ash pits, 22. curved portions, 3. threaded rod, 4. blade, 5. inlet opening, 6. grooving, 7. transition part.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the bit body 2 that the utility model comprises threaded rod 3, is connected with threaded rod 3, bit body 2 center is provided with inlet opening 5, on bit body 2 with inlet opening 5 for symmetrical centre is provided with centrosymmetric left and right seat 1, left wing's seat and right flank seat are welded with the blade 4 of the diamond compound of arc respectively, the work plane front of blade 4 is respectively equipped with ash pit 21, is connected with curved portions 22 between the side of ash pit 21 and bit body 2, and this curved portions 22 is connected with the grooving 6 on threaded rod 3.Threaded rod 3 is provided with grooving, is convenient to further deslagging.
The profile of left wing's seat and right flank seat is be positioned at same circular shape circumferentially, be positioned at left wing's seat and right flank seat is provided with cross section grooving arranged in parallel 6 near the side of ash pit 21, the cross section of this grooving 6 is arranged downwards along wing seat 1 lateral vertical, and the angle of cross section and horizontal axis is 25 ° ~ 35 °.Both sides grooving 6 and the junction of ash pit 21 are provided with phase cross section transition part parallel mutually 7, and this transition part 7 is provided with certain spacing with the full circle at wing seat 1 place.
For the ease of implementing, the distance between grooving is 24 ~ 28mm, and the distance between transition part is 20 ~ 25mm.
When the utility model is specifically implemented, drill bit creeps into, be provided with gap between the circumference at grooving and wing seat place, make to be provided with gap, by curved portions and ash pit between wing seat and boring, disintegrating slag is more easily discharged, in boring procedure, contact area reduces, and rotational resistance is little, corresponding rate of penetration promotes, thus improves operating efficiency.
