Description

A kind of integral anchor bit

Technical field

Engineering, the technical field of mine drill are the utility model is related to, more particularly to a kind of integral anchor bit.

Background technology

Anchor bit plays vital effect in the tunneling process in the fields such as engineering, mine, bit performance it is excellent It is bad to directly affects drilling efficiency and drilling cost.

, problems be present in existing anchor bit：Being substantially needs a people by adapter sleeve by drill bit and drilling rod It is fixed, its connection procedure trouble, wastes time and energy；Due to there is a tolerance clearance between drill bit and adapter sleeve, in drill bit height During speed drilling, pore-forming size less standard, uniformity is poor, so as to easily cause the hole that drills out against regulation, by this Hole is scrapped, and influences construction quality；Rubbed between drill bit and adapter sleeve big, it is big to bit wear, connected between drill bit and adapter sleeve Intensity is not high, and drill bit is easily broken off, and causes the consumption of drill bit to increase, and cost increases；The frictional force that drill bit is subject to during bit bore Not enough, easily skid, the hole for causing to drill out is not inconsistent standardization；Temperature of diamond bit is high, easily occur in work burying, paste brill, the burning of bits, The failures such as bit freezing.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of integral anchor bit.

The technical solution adopted in the utility model is：A kind of integral anchor bit, including integrally formed drill bit base portion, Arc-shaped ring groove and drill shank, described drill bit base portion includes two wing bodies helically arranged around axle center, in drill bit pedestal It is distributed in portion for radial symmetric and in the opposite direction, drill lip blade is separately installed with the upper end of two wing bodies, in the bottom of two wing bodies The position being connected with drill shank is provided with two chip areas, and the upper end of described drill shank sets two close to the outer surface of drill bit base portion to be had Arc-shaped ring groove；Waterway is provided among the drill shank, the waterway is communicated to the center of drill bit base portion, flat through a rectangle Hole delivery port is passed, and interior connection screw thread is provided with the waterway；The drill shank outer surface is provided with outside ridge design, connects inside Connect and intake chamber is provided between screw thread and outer surface, described intake chamber is at least one, and the delivery port of described intake chamber It is arranged between left wing's seat and right flank seat.

The beneficial effects of the utility model are：It is simple in construction, it is easy to operate, unitary design make drill bit have high intensity, High abrasion and shock proof ability, while multiple apopores are designed with, temperature of diamond bit is reduced, beneficial to chip removal, fault rate is reduced, prolongs Long drill bit service life；Ridge design is designed in drill bit outer surface, adds the adhesive force of drill bit, and grip is good, is not easy to skid, carries Height drilling yield.When the drill bit is crept into soft medium ground, there is that speed is fast, drilling depth is more, pore-forming dimensional uniformity is high, the life-span The advantages that length, stable working, less labor intensity.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is top view of the present utility model.

Fig. 3 is upward view of the present utility model.

In figure：1. drill lip blade, 2. wing bodies, 3. chip areas, 4. arc-shaped ring grooves, 5. delivery ports, 6. ridge designs, 7. water inlets Groove, 8. waterways, connection screw thread in 9., 10. drill shanks, 11. drill bit base portions, 12. water inlets.

Embodiment

It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model Explanation.

Such as Fig. 1, the integral anchor bit shown in 2,3, including integrally formed drill bit base portion 11, arc-shaped ring groove 4 and brill Shank 10, described drill bit base portion 11 include two wing bodies 2 helically arranged around axle center, are in drill bit base portion 11 Radial symmetric is distributed and in the opposite direction, drill lip blade 1 is separately installed with the upper end of two wing bodies 2, in the bottom of two wing bodies 2 and brill The position that shank 10 connects is provided with two chip areas 3, and chip removal speed is fast；The upper end of described drill shank 10 is close to drill bit base portion 11 Outer surface be provided with two arc-shaped ring grooves 4, beneficial to chip removal；Waterway 8 is provided among the drill shank 10, the waterway 8 is communicated to The center of drill bit base portion 11, passed through delivery port 5, water outlet great efforts, interior connection screw thread 9 is provided with the waterway 8；The brill The outer surface of shank 10 is provided with ridge design 6, and intake chamber 7, described intake chamber are provided between interior connection screw thread 9 and outer surface 7 are at least one, and the delivery port of described intake chamber 7 is arranged between two wing bodies 2.

Operation principle：Drill bit base portion 11, arc-shaped ring groove 4 and drill shank 10 of the present utility model design for integral type, Directly this drill bit is rotatably connected with drilling rod by interior connection screw thread 9 during use, it is simple and convenient using step.Integral type is set Meter avoids tolerance clearance and the friction between drill bit base portion 11 and drill shank 10, and hole position consistent degree is high in boring procedure. By waterway 8 and intake chamber 7 in boring procedure, two sets of water inlet systems of major-minor are formed, the water inlet 12 of waterway 8 is more than The mouth of a river 5 forms certain hydraulic pressure, and water column uniformly spreads in fan-shaped to both sides, and water is big, row's powder is fast；And the water of intake chamber 7 is from two Ejected between wing body 2, the dust that can effectively wash away between two wing bodies 2.The bumps flower being provided with the outer surface of drill shank 10 Line 6, the adhesive force that adds drill bit is crossed in title in bit bore, grip is good, is not easy to skid, and improves drilling yield.

The utility model is simple in construction, easy to operate, when being crept into soft medium ground, there is that speed is fast, drilling depth is more, pore-forming The advantages that dimensional uniformity height, long lifespan, stable working, less labor intensity.

Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
