Abstract
The utility model discloses a novel hard alloy excavator bucket tooth, and relates to engineering machinery, in particular to a bucket tooth structure of an excavator. The novel hard alloy excavator bucket tooth consists of a tooth holder (1) and a hard alloy tooth tip (4), wherein a connecting body (2) is arranged at the front end of the tooth holder (1); the section of the connecting body (2) has a trapezoidal structure with a narrow front end; the front end of the hard alloy tooth tip (4) is sharp-angled; a groove (5) is formed at the rear end of the hard alloy tooth tip (4); the shape of the groove (5) is as same as that of the connecting body (2); a mounting hole (3) for running through two sides is formed on the connecting body (2); a mounting outer hole (6) corresponding to the mounting hole (3) is formed on two sides of the groove (5); the connecting body (2) is inserted into the groove (5); and a dowel passes through the mounting hole (3) and the mounting outer hole (6) to fixedly connect the tooth holder (1) with the hard alloy tooth tip (4). The novel hard alloy excavator bucket tooth solves the problems that the conventional excavator bucket tooth has low wear resistance, low hardness and short service life.
Description
Technical field
The utility model relates to engineering machinery, is specifically related to the bucket tooth structure of excavator.
Background technology
Excavator is claimed excavation machinery again, is to excavate with scraper bowl to be higher or lower than the material that holds machine side, and the haulage vehicle or unload the earth moving plant to rickyard of packing into.
The material that excavator excavates mainly is soil and the rock behind soil, coal, silt and the preparatory pine of process.From the development of engineering machinery in recent years, the development of excavator is very fast relatively, and excavator is as one of topmost engineering machinery type in the engineering construction, and it is even more important that its correct type selecting also just seems.
Excavator bucket teeth is the important easy consumption parts on the excavator, is similar to people's tooth, and by the combination bucket tooth that toothholder and crown are formed, the two leans on bearing pin to connect.Because the bucket tooth wear out failure partly is a crown, as long as change the tool point.
Existing excavator bucket teeth existence wears no resistance, and hardness is low, the problem that application life is short.
Summary of the invention
The utility model provides a kind of novel hard alloy excavator bucket teeth, and the utility model has solved existing excavator bucket teeth and worn no resistance, and hardness is low, the problem that application life is short.
For addressing the above problem, the utility model adopts following technical scheme: a kind of novel hard alloy excavator bucket teeth is made up of toothholder 1 and carbide alloy crown 4; The front end of toothholder 1 has connector 2, and the cross section of connector 2 is trapezium structures of inswept; The front end of carbide alloy crown 4 is pointed shape, and the rear end of carbide alloy crown 4 is fluted 5, and groove 5 shapes are identical with connector 2 shapes; The installing hole 3 that runs through both sides is arranged on the connector 2, and there is the outer hole 6 of the installation corresponding with installing hole 3 positions groove 5 both sides; Connector 2 is inserted in the groove 5, and pin passes installing hole 3 and with the outer hole 6 of installation toothholder 1 is fixedly connected with carbide alloy crown 4.
The carbide alloy excavator bucket teeth of the utility model, its crown has the hardness height, and abrasion resistance is good, the advantage of long service life.
Description of drawings
Fig. 1 is the utility model lateral view.
Symbol description among the figure: toothholder 1, connector 2, installing hole 3, carbide alloy crown 4, groove 5, the outer hole 6 of installation.
The specific embodiment
With illustrated embodiments the utility model is done detailed explanation below.
As shown in Figure 1, a kind of novel hard alloy excavator bucket teeth is made up of toothholder 1 and carbide alloy crown 4; The front end of toothholder 1 has connector 2, and the cross section of connector 2 is trapezium structures of inswept; The front end of carbide alloy crown 4 is pointed shape, and the rear end of carbide alloy crown 4 is fluted 5, and groove 5 shapes are identical with connector 2 shapes; The installing hole 3 that runs through both sides is arranged on the connector 2, and there is the outer hole 6 of the installation corresponding with installing hole 3 positions groove 5 both sides; Connector 2 is inserted in the groove 5, and pin passes installing hole 3 and with the outer hole 6 of installation toothholder 1 is fixedly connected with carbide alloy crown 4.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
