Background technology
Rock drilling is the operation of utilizing rock drilling equipment Drilling borehole or big gun hole in the rock of ore deposit.Main by mechanical rock drilling method, divide impact type, rotary and rotary impact type according to drilling tool manner of execution.In the time that rock drilling is holed, brill is cut a hole in the working end that the bore bit that is applicable to strata structure need to be installed on to rock drilling equipment, and bore bit adopts high-quality imported steel, and cutter head adopts specific alloy to be made through special processing welding technique.Existing bore bit is mainly divided into in-line, cross, ball profile of tooth, in-line is applicable to the not high rock stratum of jackhammer Drilling hardness, be convenient to reconditioning, cross is suitable under the condition with greater impact merit hammer drill, the rock stratum that Drilling Fractured rock stratum and abrasion are strong, and the anti-ability of radially denuding is strong, ball profile of tooth has under the condition of greater impact merit hammer drill, stronger than the sheet bore bit applicability of inserting, cutting rate and life-span are high, and the pass of digging out is round.
The ball tooth type bot pick head using at present, its in use, often due to structure and the bore bit self structure problem of rock ore bed, easily occur the bobbing of bore bit, this bobbing, very easily causes the planeness of the inner machined surface of petrosal foramen, affect drilling quality, even, in the time that bobbing is larger, easily cause bore bit fracture, and existing bore bit afterbody is generally cylindrical, easily cause back-blading rock slag, card pricker occurs, and the problem that exits that it directly affects bore bit, causes bore bit to scrap.
Summary of the invention
The purpose of this utility model is, multi-function ball tooth Seizing-proof rock-drill bit is provided, and the bore bit card pricker causing for the fault of construction of existing ball tooth type bot pick head is scrapped problem.
To achieve these goals, the technical solution of the utility model is specific as follows:
Multi-function ball tooth Seizing-proof rock-drill bit, comprise pricker storehouse 1, working end 2, bore sharp rotor 3, center cue ball tooth 4, water hole 5, peripheral ball tooth 6, ash pit 7, it is characterized in that, 1 one end, pricker storehouse arranges working end 2, the other end is provided with blind hole, described pricker storehouse 1, its structure is specially the frustum of a cone, and outside, frustum of a cone one end is distributed with linear mill quarrel groove, described working end 2, its outer surface is distributed with ash pit 7, described working end 2, its upper surface is provided with cone boss, described working end 2, on its cone boss, be provided with the sharp rotor 3 of cone, center cue ball tooth 4, water hole 5, described cone point rotor 3, it is specifically arranged at the cone boss upper surface center of described working end 2, described cone point rotor 3, longitudinal center's axis two ends of its radial section are respectively arranged with water hole 5, central transverse axis two ends are respectively arranged with center cue ball tooth 4, described working end 2, on its cone boss outer surface, be evenly distributed with peripheral ball tooth 6.
Described multi-function ball tooth Seizing-proof rock-drill bit, is characterized in that, described working end 2, and the bottom surface diameter of the cone boss of its upper surface is consistent with working end 2 end face diameters.
Described multi-function ball tooth Seizing-proof rock-drill bit, is characterized in that, described cone point rotor 3, and it is specially rectangular pyramid.
Described multi-function ball tooth Seizing-proof rock-drill bit, is characterized in that, described center cue ball tooth 4, and its diameter is less than the diameter of described peripheral ball tooth 6.
The beneficial effects of the utility model are, simple in structure, novel in design, practical reliable, simple to operation, bore the design of sharp rotor 3, can ensure center cue ball tooth 4, peripheral ball tooth 6 is in the time cutting a hole brill to rock stratum, keep stable axial linear movement, effectively prevent this device in the time that rock drilling is rotated to the bobbing around petrosal foramen, improve rotating speed, reduce this and installed the peripheral degree of wear and rotary resistance, further strengthen petrosal foramen circularity quality, the design of ash pit 7, can effectively the rock slag producing in rock drilling process be discharged around working end 2 in time, prevent rubble card pricker probability, the circular cone desktop designs in pricker storehouse 1, increase pricker storehouse 1 afterbody activity space, rock slag is discharged more smooth, in the time carrying out rock stratum cutter brill, the frustum of a cone outer surface in pricker storehouse 1 can make stone loosening in petrosal foramen along with the rising in pricker storehouse 1 is returned original position again and do not blocked pricker, the back-blading rock slag of effectively having avoided the cylinder design in traditional rock pricker pricker storehouse to form, cause card pricker problem, the design of the linear mill quarrel groove in pricker storehouse 1, can grind rock quarrel and sillar corner angle residual in petrosal foramen, improve and moved back pricker efficiency.
