Description
Technical field
This utility model relates to a kind of coal seam drilling exploration and digs apparatus, and especially a kind of multiple wing diamond compact is anti-buries reaming bit.
Background technology
Diamond compact bit, whole drill bit does not has the parts of activity, relatively simple for structure, is one of the big new technique of world well three eighties in 20th century.Onsite application proves, when diamond compact bit creeps in soft-medium ground, has the advantages such as speed is fast, drilling depth is many, life-span length, stable working, down-hole accident are few, wellbore quality is good.And relative to diamond bit there is low cost, the advantage such as applied widely.It is three wings diamond compact Noncoring drill bits that coal seam drilling exploration so now digs commonly use, but for this three wings diamond compact Noncoring drill bit release press construction exists fixed point perforate easily offset, rate of penetration low；Deslagging efficiency is low, and drill body area is big, and compression area increases easy burying, is difficult to move back brill, the defect that the big impact of frictional force is crept into.There is presently no good solution.
Summary of the invention
During overcoming the present coal seam drilling exploration to dig, drill bit release press construction exists fixed point perforate easily offset, rate of penetration low, deslagging efficiency is low, and drill body area is big, and compression area increases easy burying, the problem that the big impact of frictional force is crept into；This utility model provides that a kind of multiple wing diamond compact is anti-buries reaming bit, and the fixed point perforate of this drill bit is stable, creep into, speed of slagging tap fast, and arrange super large water hole, improve ash-retention efficiency, move back drilling speed degree and can effectively prevent burying soon.
Utility model solves its technical problem the technical scheme is that multiple wing diamond compact and prevents burying reaming bit, including: front end minister's body drill bit, outlet, drill main body body mandrel, upper three wings wing body are bored, middle three wings wing body is bored, rear three wings wing body is bored, connector；nullThis multiple wing diamond compact prevents that burying reaming bit has the drill main body body mandrel of a hollow cylindrical，Outlet is left outside its end，Front end minister's body drill bit is had in drill main body body mandrel exterior horizontal positioned the most successively、Upper three wings wing body is bored、Middle three wings wing body is bored、Rear three wings wing body is bored，Totally four group of 12 wing，Often leave space between group wing body，And the inclination angle of wing body upper knife edge is 15 degree，Spacing drift angle between wing body is 30 degree，And form helical structure with drill main body，Middle three wings wing body is bored peripheral diameter and is bored more than upper three wings wing body、Rear three wings wing body is bored，The upper three wings wing body brill that rear three wings wing body drill sword direction and direction are protruding forward、Middle three wings wing body drill sword is in opposite direction and protruding backward arranges，This protruding advantage arranged backward is easily to move back brill，It is not susceptible to burying，Connector is had at drill main body body mandrel bottom welding，Connector top is provided with intake tunnel.
Multiple wing diamond compact is anti-bury reaming bit due to front end minister's body drill bit creep into time, wing body blade cutting in front end is initially formed at the bottom of aperture, and back wing body blade creeps on the basis of front end is small-bore and is easier to cutting；The inclination angle of wing body upper knife edge is 15 degree, and the spacing drift angle between wing body is 30 degree, and forms helical structure with drill main body, it is simple to the derivation of rock (coal) slag, reduces pressure area, and brill wing body blade cutting is moved back in increase, prevents burying.
Drill bit wing body quantity increases, and forms multilamellar wing body structure multilamellar and goes forward one by one cutting, cuts aperture from small to large, compare the drill bit of more single diameter, improve and creep into and move back brill efficiency, decrease drill bit time of staying in hole, reduce burying probability, improve drilling effect.
The beneficial effects of the utility model are: this utility model provides a kind of multiple wing diamond compact to prevent burying reaming bit, the fixed point perforate of this drill bit is stable, creep into, speed of slagging tap fast, and arrange super large water hole, improve ash-retention efficiency, move back drilling speed degree and can effectively prevent burying soon, strong to creeping into environmental suitability, there is stronger practical application.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In the drawings: 1. front end minister body drill bit, 2. outlet, 3. drill main body body mandrel, 4. go up three wings wing body bore, 5. in three wings wing body bore, 6. after three wings wing body bore, 7. connector, 8. intake tunnel.
Detailed description of the invention
In FIG, multiple wing diamond compact is anti-buries reaming bit, including: front end minister's body drill bit 1, outlet 2, drill main body body mandrel 3, upper three wings wing body brill 4, middle three wings wing body brill 5, rear three wings wing body brill 6, connector 7；nullThis multiple wing diamond compact prevents that burying reaming bit has the drill main body body mandrel 3 of a hollow cylindrical，Outlet 2 is left outside its end，Outside drill main body body mandrel 3, horizontal positioned has front end minister's body drill bit 1 the most successively、Upper three wings wing body bores 4、Middle three wings wing body bores 5、Rear three wings wing body bores 6，Totally four group of 12 wing，Often leave space between group wing body，And the inclination angle of wing body upper knife edge is 15 degree，Spacing drift angle between wing body is 30 degree，And form helical structure with drill main body，Middle three wings wing body is bored 5 peripheral diameters and is bored 4 more than upper three wings wing body、Rear three wings wing body bores 6，The upper three wings wing body that rear three wings wing body bores 6 blade directions protruding forward with direction bores 4、It is in opposite direction and protruding backward arrange that middle three wings wing body bores 5 blades，This protruding advantage arranged backward is easily to move back brill，It is not susceptible to burying，The connector 7 of rig is had at drill main body body mandrel 3 bottom welding，Connector 7 top is provided with intake tunnel 8.
Multiple wing diamond compact is anti-bury reaming bit due to front end minister's body drill bit 1 creep into time, wing body blade cutting in front end is initially formed at the bottom of aperture, and back wing body blade creeps on the basis of front end is small-bore and is easier to cutting；The inclination angle of wing body upper knife edge is 15 degree, and the spacing drift angle between wing body is 30 degree, and forms helical structure with drill main body body mandrel 3, it is simple to the derivation of rock (coal) slag, reduces pressure area, and brill wing body blade cutting is moved back in increase, prevents burying.
Drill bit wing body quantity increases, and forms multilamellar wing body structure multilamellar and goes forward one by one cutting, cuts aperture from small to large, compare the drill bit of more single diameter, improve and creep into and move back brill efficiency, decrease drill bit time of staying in hole, reduce burying probability.Improve drilling effect.
