Adopt the wear -resisting cover of prong top suit for the prong replaces prong work, wearing and tearing at the during operation by wear -resisting cover, and with the help of bolted connection's wear -resisting cover change convenience, the enhancement strip of setting can alleviate prong direct contact ground etc. Reducing wear.
Description
Technical field
This utility model belongs to engineering equipment field, is specifically related to the bucket tooth assembly of a kind of novel high-performance.
Background technology
Excavator bucket teeth is the vitals on excavator, is similar to the tooth of people, is also consumable accessory, the Dipper Teeth being made up of toothholder and crown, and the two connects by bearing pin.Owing to bucket tooth wear out failure part is crown, as long as changing tool point.
Excavator is operationally, ground etc. is baited out by bucket tooth, to facilitate the entrance of bucket, therefore the abrasion of crown and the problem of fractureing happen occasionally, and the maintenance of bucket tooth and replacing need cost also higher, and the bucket tooth under changing all directly is scrapped substantially, causes the wasting of resources, bring no small cost to engineering construction and put into.
Utility model content
This utility model is in order to solve above-mentioned problems of the prior art, and this utility model provides the bucket tooth assembly of a kind of novel high-performance, it is possible to extends the service life of bucket tooth, facilitates the maintenance of bucket tooth to change so that maintenance cost reduces, and saves fund input.
The concrete technical scheme that this utility model adopts is:
A kind of bucket tooth assembly of novel high-performance, including toothholder and crown, crown is sleeved on toothholder, toothholder is connected by bearing pin with crown, and described crown top is set with wear-resistant sleeve, and wear-resistant sleeve vertical cross-section is isosceles trapezoidal structure, the inner side of crown is provided with screwed hole, being provided with counter sink on wear-resistant sleeve, counter sink is arranged with screwed hole dead in line, and wear-resistant sleeve is by being arranged on being bolted on crown in counter sink.
The base angle of the wear-resistant sleeve of described isosceles trapezoid is 60 °.
The two sides up and down of described crown are both provided with stiffener.
The front end of described stiffener is wedge structure, and wherein fit with the end face of crown in the front end of stiffener.
Being provided with three groups of stiffeners on described crown lower surface, three groups of stiffeners are arranged side by side along the length direction of crown, and the stiffener of both sides is symmetrical arranged, and the stiffener height in centre position is more than both sides stiffener.
The beneficial effects of the utility model are:
This utility model, adopts crown top suit wear-resistant sleeve so that crown is operationally substituted crown work, abrasion by wear-resistant sleeve, and it is convenient to change by bolted wear-resistant sleeve, the stiffener of setting, it is possible to alleviate crown directly contact face etc., reduces abrasion.

Fig. 3 is the schematic diagram of section B-B in Fig. 1；
In accompanying drawing, 1, crown, 2, wear-resistant sleeve, 3, counter sink, 4, stiffener.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail:
Specific embodiment is as shown in Figure 1, Figure 2 and Figure 3, this utility model is the bucket tooth assembly of a kind of novel high-performance, including toothholder and crown 1, crown 1 is sleeved on toothholder, toothholder is connected by bearing pin with crown 1, described crown 1 top is set with wear-resistant sleeve 2, wear-resistant sleeve 2 vertical cross-section is isosceles trapezoidal structure, the inner side of crown 1 is provided with screwed hole, wear-resistant sleeve 2 is provided with counter sink 3, counter sink 3 is arranged with screwed hole dead in line, and wear-resistant sleeve 2 is by being arranged on being bolted on crown 1 in counter sink 3.Being arranged on the wear-resistant sleeve 2 on crown 1 top to substitute crown 1 and wear and tear, protect crown 1, wear-resistant sleeve 2 is compared to crown 1, and volume is little, materials are few, and relative cost is relatively low, and when changing, loss cost is smaller, effectively prevent the damage of crown 1.
The base angle of the wear-resistant sleeve 2 of described isosceles trapezoid is 60 °.The two sides up and down of described crown 1 are both provided with stiffener 4.Stiffener 4 improves the bending resistance of crown 1 and ensure that by force the ruggedness of crown 1, and the front end of described stiffener 4 is wedge structure, and wherein fit with the end face of crown 1 in the front end of stiffener 4.So that crown 1 inserts in soil, ground.
Being provided with three groups of stiffeners 4 on described crown 1 lower surface, three groups of stiffeners 4 are arranged side by side along the length direction of crown 1, and the stiffener 4 of both sides is symmetrical arranged, and stiffener 4 height in centre position is more than both sides stiffener 4.Middle prominent stiffener 4 is when crown 1 top is to hard objects, it is ensured that crown 1 is bigger with the distance of object, it is prevented that the problem that hard objects directly contacts crown 1 and damages occurs.
