Abstract
The utility model provides a go into rock and inlay alloy bit, the shaping structure is milled to this as an organic wholeization of drill bit of, and this structure is doublestage stair structure, first order step is the drill bit fixing base, and it is used for supporting whole drill bit structure, and second level step is used for accomplishing the cutting of work progress for the drill bit main part, each go into rock and inlay alloy bit is assembled the fixed combined type drill bit of constituteing through the locating piece and is carried out the breakage. This structure is a combination formula ladder shape, is applicable to the operational environment into rock pile rig, the appearance cross -section of this structure is fan -shaped, and it is broken during with the gyration cutting that this fan -shaped structure makes the drill bit strike, and peripheral velocity is impartial, fractured rock that can be even, and crushing effect is good, provides very good prerequisite for getting rid of of follow -up disintegrating slag. Inlay the alloy on the sector of drill bit main part, also inlay simultaneously the alloy on the excessive arc curved surface of drill bit fixing base and drill bit main part junction, the alloy on the arc curved surface also can broken or stone roller rock crushing like this, reaches fine crushing effect.
Description
Technical field
The utility model relates to the technical field into rock Piling drilling rig, and particularly one enters rock edge alloy bit.
Background technology
In prior art, carrying out in rock-soil layer pile foundation construction, the piling construction of rock-soil layer drilling equipment or the pneumatic down-hole hammer adopting revolution cutting boring mode more, but the output torque of revolution cutting type drilling equipment and drilling pressure are under the condition of high load capacity, complete machine configuration requirement is high, the cost of drilling equipment is higher, and the spoilage of drill bit and main frame is also higher.
Drill bit is requisite part in common engineering construction equipment, and its design feature directly determines the height of efficiency of construction.Existing enter rock drill hammer be main mainly with circle, the shortcoming and defect such as efficiency of construction is low, and penetration rate is slow.
Summary of the invention
The utility model carries out finishing structure optimization on the basis of existing piling drill bit, provides the rock that enters that a kind of structure is simple, crushing effect good, construction penetration rate is fast, operating efficiency is high and inlays alloy bit.This drill bit effectively can promote operating efficiency and the working level of piling drill bit.
For achieving the above object, the technical solution adopted in the utility model is that one enters rock edge alloy bit, the integrated milling molding structure of this drill bit, and this structure is twin-stage ledge structure; First order step is drill bit holder (1), and it is in order to support whole drill bit structure, and second level step is that drill main body (2) is in order to complete the cutting of work progress; Wherein, the appearance and size of drill bit holder (1) is greater than the appearance and size of drill main body (2), and drill bit holder (1) is arc-shaped curved surface structure with the transition face of drill main body (2) junction; The cross section of drill bit holder (1) and drill main body (2) is fan-shaped; The bottom sides of drill bit holder (1) is provided with radial fixing hole (3); The surface of drill main body (2) is provided with protruding alloy (4); The center, the back side of drill bit holder (1) is provided with axial location hole (5).
Respectively enter rock edge alloy bit to carry out assembled fixing composition combination type drill bit by locating piece and carry out fragmentation.
Compared with prior art, the utility model has following beneficial effect.
1, this structure is Combined stepped shape, is applicable to the working environment into rock Piling drilling rig; Compared with the architectural feature of existing routine, crushing effect of the present utility model is better.
2, the exterior cross-section of this structure is fan-shaped, this sector structure make drill bit impact broken and revolution is cut time, peripheral velocity is impartial, can fractured rock uniformly, and crushing effect is good, and the eliminating for follow-up disintegrating slag provides extraordinary prerequisite.
Embedded alloy on the sector of 3, drill main body, simultaneously also embedded alloy on the excessive arc-shaped curved surface of drill bit holder and drill main body junction, the alloy on such arc-shaped curved surface also can be broken or roll crushed rocks, reaches good crushing effect.

Fig. 3 is the front schematic view of this structure;
Fig. 4 is the Combination application schematic diagram of this structure;
In figure: 1, drill bit holder, 2, drill main body, 3, radial fixing hole, 4, protruding alloy, 5, axial location hole.
Detailed description of the invention
As Figure 1-4, one enters rock edge alloy bit, and this edge alloy bit profile is unique sector structure, and this sector structure designs fan-shaped size according to the size of stake holes.The cross section that edge alloy bit hits position, rock stratum is fan-shaped.Because stretch out from stake holes center line, along with the increase of diameter, linear velocity is circumferentially different, this is trapezoidal make drill bit impact broken and revolution is cut time, peripheral velocity is impartial, can fractured rock uniformly, crushing effect is good, and the eliminating for follow-up disintegrating slag provides extraordinary prerequisite.It is fan-shaped that edge alloy bit hits position, rock stratum, is slope shape or ladder-type structure in trapezoidal surrounding.This structure is beneficial to when drill bit revolution is cut and crosses and pulverize irregular rock, makes catalase refinement, is beneficial to follow-up deslagging.
