Description
Technical field
The utility model relates to rock drilling boring equipment technical field, particularly multi-functional cross Seizing-proof rock-drill bit.
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, according to drilling tool manner of execution, divide impact type, rotary and rotary impact type.When 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 applicable to be had under the condition of 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 bull bit using at present, its in use, often due to structure and the bore bit self structure problem of rock ore bed, the bobbing that easily occurs bore bit, this bobbing, very easily causes the planeness of the inner machined surface of petrosal foramen, affect drilling quality, even, when 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-functional cross Seizing-proof rock-drill bit is provided, the bore bit card pricker, the bore bit breakage problem that for the fault of construction of existing bull bit, cause.
To achieve these goals, the technical solution of the utility model is specific as follows:
Multi-functional cross Seizing-proof rock-drill bit, comprise storehouse body 1, working end 2, ash pit 3, water hole 4, cross alloy blade 5, alloy rotor 6, it is characterized in that, body 1 one end in storehouse arranges working end 2, the other end is provided with blind hole, described storehouse body 1, its structure is specially rounding frustum, described storehouse body 1, on its one end external surface, be evenly distributed with linear deslagging groove, described working end 2, its upper surface arranges cross alloy blade 5, described cross alloy blade 5, its center infall is provided with alloy rotor 6, described working end 2, the place, outer of four quadrants that its upper surface is partitioned into by described cross alloy blade 5 is respectively arranged with ash pit 3, and corresponding ash pit 3 one sides are respectively arranged with water hole 4.
Described multi-functional cross Seizing-proof rock-drill bit, is characterized in that, described alloy rotor 6, and its structure is specially rectangular pyramid.
The beneficial effects of the utility model are, simple in structure, novel in design, practical reliable, simple to operation, the design of alloy rotor 6, can guarantee that cross alloy blade 5 is when cutting a hole brill to rock stratum, keep stable axial linear movement, effectively prevent this device when rock drilling is rotated to petrosal foramen bobbing around, improved rotating speed, reduce this and installed the peripheral degree of wear and rotary resistance, further strengthened petrosal foramen circularity quality, improved cutting rate, ash pit 3, the design in water hole 4, can effectively the rock slag producing in rock drilling process be discharged in time around working end 2, prevented rubble card pricker probability, reduced working end 2 rubble amount around, the inverted cone desktop designs of storehouse body 1, increased storehouse body 1 afterbody activity space, rock slag is discharged more smooth, when carrying out rock stratum cutter brill, the rounding frustum outer surface of storehouse body 1 can make stone loosening in petrosal foramen along with the rising of storehouse body 1 is returned original position again and do not blocked pricker, effectively avoided the back-blading rock slag of the cylinder design formation in traditional rock pricker pricker storehouse, cause card pricker problem, the design of the linear mill quarrel groove of storehouse body 1, can rock quarrel and sillar corner angle residual in petrosal foramen be ground, improved and moved back pricker efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of storehouse of the present utility model body.
Fig. 3 is top view of the present utility model.
Wherein, 1. storehouse body, 2. working end, 3. ash pit, 4. water hole, 5. cross alloy blade, 6. alloy rotor.
The specific embodiment
Multi-functional cross Seizing-proof rock-drill bit, comprises storehouse body 1, working end 2, ash pit 3, water hole 4, cross alloy blade 5, alloy rotor 6.
As shown in Figure 1 and Figure 2, body 1 one end in storehouse arranges working end 2, the other end is provided with blind hole, described storehouse body 1, and its structure is specially rounding frustum, described storehouse body 1, on its one end external surface, be evenly distributed with linear deslagging groove, described working end 2, its upper surface arranges cross alloy blade 5, described alloy rotor 6, its structure is specially rectangular pyramid.
