Abstract
The utility model discloses a rotary bit. The rotary bit comprises a bit handle, a bit head and a cemented carbide head. The rear end of the cemented carbide head is embedded into an installation groove formed in the bit head. A plurality of gauge protection strips are embedded into the wall of the installation groove formed in the bit head. Each gauge protection strip and the cemented carbide head are made of the same material. According to the rotary bit, due to the facts that the gauge protection strips are arranged in the installation groove of the bit head and each gauge protection strip and the cemented carbide head are made of the same material, when the rotary bit is operated, the gauge protection strips and the cemented carbide head are evenly abraded, the phenomenon that the installation groove is worn out ahead of a set time is avoided, and disengagement of the cemented carbide head is avoided. The gauge protection strips can also prevent eccentric wear of the bit head, so that the bit head is effectively protected. The front end of the cemented carbide head is evenly worn, so that the cemented carbide head is sharp all the time and is free of bluntness. According to the rotary bit, the service life is effectively prolonged, and work efficiency is improved. The rotary bit has the advantages of being scientific and reasonable in structural design and high in practicability.
Description
Technical field
The utility model relates to and a kind ofly for revolving of rotary drilling rig operation, digs tooth.
Background technology
In China, revolve that to dig the output of tooth increasing, now used revolving dug tooth and mainly tooth handle, tooth head, consisted of, tooth head upper surface welding hard alloy head.This kind of structure due to structure design reason, alloy head around steel body hardness is lower, easily wearing and tearing, cause carbide alloy early fallout, affect the application life of pick.
Summary of the invention
The purpose of this utility model is to provide revolving of a kind of hard alloy head difficult drop-off to dig tooth.
In order to solve the problems of the technologies described above, the utility model comprises tooth handle, tooth head and hard alloy head, the rear end of hard alloy head is embedded in the mounting groove on tooth head, on the cell wall of the mounting groove on described tooth head, embeds and has a plurality of gauge bars, the material that gauge strip adoption is identical with hard alloy head.
In order to make gauge bar fixed, described gauge bar and tooth head are welded to connect.
In order better to protect hard alloy head, described gauge bar is strip, and the length direction of gauge bar is on the depth direction of mounting groove, and the rear end of hard alloy head and the bottom land of mounting groove are welded to connect.
In order to reduce at work resistance, described gauge bar and mounting groove all have tapering, the more close mounting groove center line in the relative rear end of front end of gauge bar and mounting groove, and front end and the mounting groove front end of described gauge bar are equipped with chamfering.
In order to have good cost performance, described gauge bar has 3-12 bar, and all gauge bar circumference uniform distributions are in the cell wall of mounting groove.
For the ease of making, the cross section of the width of described gauge bar is circle, semicircle or polygon.
In order to be conducive to the rotation of tooth head, the outer wall of described tooth head is provided with a plurality of grooves.
For the ease of being connected with toothholder, described tooth handle is provided with jump ring.
The beneficial effects of the utility model: the utility model is owing to being provided with gauge bar in the mounting groove at tooth head, the material that gauge strip adoption is identical with hard alloy head, revolve while digging tooth work, gauge bar and hard alloy head are worn and torn uniformly, mounting groove can not be worn in advance, can not cause hard alloy head to come off.Gauge bar can also prevent the generation of tooth head eccentric wear phenomenon, has effectively protected tooth head.The front end of hard alloy head weares and teares equably, makes hard alloy head always in sharp state, can not send out blunt.The utility model has effectively extended and has revolved the application life of digging tooth, has improved operating efficiency.There is scientific structure design, reasonable, practical effect.

The specific embodiment
Specific embodiment one
As depicted in figs. 1 and 2, it comprises tooth handle 1, tooth head 2, hard alloy head 3, gauge bar 4 and jump ring 5.
The rear end of hard alloy head 3 is embedded in the mounting groove on tooth head 2, on the cell wall of the mounting groove on tooth head 2, embeds and has a plurality of gauge bars 4, and gauge bar 4 adopts the material identical with hard alloy head 3.
The number of gauge bar 4 will be determined according to the size of hard alloy head 3, is generally 3-12.All gauge bar 4 circumference uniform distributions are in the cell wall of mounting groove.Gauge bar 4 is strip, and the length direction of gauge bar 4 is on the depth direction of mounting groove, and the rear end of hard alloy head 3 and the bottom land of mounting groove are welded to connect.Gauge bar 4 is welded to connect with tooth head 2.Gauge bar 4 and mounting groove all have tapering, the more close mounting groove center line in the relative rear end of front end of gauge bar 4 and mounting groove, and front end and the mounting groove front end of described gauge bar 4 are equipped with chamfering.Cross section on the width of gauge bar 4 is square, and this cross section is also with circular, semicircle or other polygon.Tooth handle 1 is provided with jump ring 5, can make to revolve to dig tooth and be movably arranged on toothholder, is convenient to digging the rotation of tunneling gear head.
Specific embodiment two
As shown in Figure 3 and Figure 4, this specific embodiment is with the difference of specific embodiment one: the outer wall of the tooth head 2 of this specific embodiment is provided with a plurality of grooves 6.
