Abstract
The utility model discloses an efficient rotary excavating tooth. The efficient rotary excavating tooth comprises a tooth handle, a tooth body and a tooth head. The tooth head comprises a cylinder part and a conical head located at the front end of the cylinder part. The cylinder part of the tooth head is embedded into an installation groove in the front end of the tooth body. A plurality of gauge protection strips are embedded into the outer circumference of the wall of the installation groove in the tooth body. The tooth head comprises a hard-alloy body, a diamond layer is arranged at the front end of the hard-alloy body, the conical face of the conical head of the tooth head is formed through the diamond layer, and the gauge protection strips and the hard-alloy body are made of the same materials. When the efficient rotary excavating tooth works, the gauge protection strips play a role so that the tooth body can be hardly abraded and the tooth head cannot disengage, the rigidity of the tooth head is further improved through the diamond layer, and the possibility of abrasion of the tooth head is reduced. The hard-alloy gauge protection strips can prevent the tooth head from being abraded eccentrically, and the tooth head is effectively protected, is in the sharp state all the time and cannot be blunt. The working efficiency of the efficient rotary excavating tooth is greatly improved, and the service life of the efficient rotary excavating tooth is greatly prolonged.

Applicant applies in 2013.11.13, number of patent application is that 2013207148960 utility model patent records one and revolves and dig tooth, it 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, embed and have multiple gauge bars, the material that gauge strip adoption is identical with hard alloy head.Thisly revolve that to dig the hard alloy head wearing and tearing of tooth very fast.
Summary of the invention
The purpose of this utility model is: provide a kind of nonabradable efficient rotary to dig tooth.
In order to solve the problems of the technologies described above, the utility model comprises tooth handle, denticle and tooth head, tooth head comprises column part and is positioned at the conehead of column part front end, the column part of tooth head is embedded in the mounting groove of denticle front end, on the excircle of the cell wall of the mounting groove on described denticle, embed and have multiple gauge bars, tooth head comprises cemented carbide body, the front end of cemented carbide body has one deck diamond layer, diamond layer forms the conical surface of the conehead of tooth head, the material that gauge strip adoption is identical with cemented carbide body.
Described gauge bar and denticle are welded to connect, and described gauge bar and denticle are welded to connect, and the cemented carbide body of the front end of gauge bar and tooth head is welded to connect.Gauge bar and diamond composite teeth head are closely connected together, and are welded into one simultaneously, have further protected mounting groove, can not cause tooth head early fallout.
In order better to protect tooth head, described gauge bar is strip, and the length direction of gauge bar is on the depth direction of mounting groove, and the cemented carbide body of tooth head and the cell wall of mounting groove and bottom land are welded to connect.
In order to reduce at work resistance, described gauge bar has tapering, the more close mounting groove center line in the relative rear end of front end of gauge bar, and the front end of gauge bar and mounting groove front end are equipped with chamfering.
In order to have good cost performance, described gauge bar has 3-10 bar, and all gauge bars are distributed in the excircle of cell wall of mounting groove.
For the ease of making, the cross section of the width of described gauge bar is square, circular, semicircle or polygon.
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 carbide alloy gauge bar in the mounting groove of tooth head, revolve while digging tooth work, gauge bar plays a role, denticle is worn hardly, tooth head does not come off, and tooth head adopts cemented carbide body and is compounded in the diamond layer of cemented carbide body front end, forms diamond composite teeth head, further improve the firm of tooth head, reduced the possibility of tooth head wearing and tearing.Carbide alloy gauge bar can also prevent the generation of tooth head eccentric wear phenomenon, effectively protects tooth head, makes tooth first straight in sharp state, can not send out blunt.Greatly improve and revolved operating efficiency and the application life of digging tooth.
