Description
Technical field
This utility model belongs to excavator technical field, is specifically related to a kind of excavator bucket teeth.
Background technology
Excavator bucket teeth is the vitals on excavator, is usually used on power shovel for protecting scraper bowl, during work
Bucket tooth tip contacts with being mined thing, and stress is maximum, during contacting material surface, crown position, due to speed, bucket tooth point
Part is by stronger impact, if the yield strength of bucket tooth is low, it will be deformed in tip, if material is harder rock
Stone, concrete etc., frictional force will be the biggest；The result of this process repeated action is that crown abrasion is very fast, due to mill
Damaging disabling portion is crown, and is to change whole bucket tooth in real work now, wastes material, increases job costs.
Utility model content
For solving the problems referred to above, the utility model discloses a kind of excavator bucket teeth, simple in construction, only change crown, joint
About material, reduces cost.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of excavator bucket teeth, it is characterised in that: include that bonding pad, working area and crown, described bonding pad are top
The hollow inverted trapezoidal structure of opening, side, bonding pad is provided with connecting hole, and described working area is arranged between bonding pad and crown, work
Making district's size from top to bottom to be gradually reduced, before and after working area, two ends, face are provided with blowpit, are provided with vertically inside described working area
Through hole, described crown is solid frustum cone structure, up big and down small, and crown outer layer is provided with wearing layer, and on described crown, plane is provided with
With the groove of screw, bolt connects crown through through hole.
As a kind of improvement of the present utility model, described through hole is arranged over countersunk recesses, and bolt is hexagon socket head cap screw, institute
State bolt head to be arranged in countersunk recesses.
As a kind of improvement of the present utility model, described blowpit is gradually provided with reinforcement.
As a kind of improvement of the present utility model, described blowpit seamlessly transits with crown.
As a kind of improvement of the present utility model, described bonding pad, working area and crown are on the same axis.
As a kind of improvement of the present utility model, described wearing layer is Aluminum Bronze layer.
The beneficial effects of the utility model are:
A kind of excavator bucket teeth described in the utility model, employing split-type structural, simple in construction, after crown weares and teares,
Unclamp bolt, change crown, without all changing whole bucket tooth, change simple and convenient, and reduce integral replacing bucket tooth
Cost, saved material.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model, it should be understood that following specific embodiment party
Formula is merely to illustrate this utility model rather than limits scope of the present utility model.It should be noted that make in describing below
Word "front", "rear", "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively
Be directed towards or away from the direction of particular elements geometric center.
As it can be seen, a kind of excavator bucket teeth described in the utility model, including bonding pad 1, working area 2 and crown 3, institute
Stating bonding pad 1 is the hollow inverted trapezoidal structure for upper opening, and side, bonding pad 1 is provided with connecting hole 4, and described working area 2 is arranged
Between bonding pad and crown, working area 2 size from top to bottom is gradually reduced, and before and after working area 2, two ends, face are provided with blowpit
5, described working area 2 is internal is provided with vertical through hole 6, and described crown 3 is solid frustum cone structure, up big and down small, and crown 3 outer layer sets
Having wearing layer 7, on described crown 3, plane is provided with the groove 8 of band screw, and bolt 9 connects crown 3 through through hole.
A kind of excavator bucket teeth described in the utility model, uses split-type structural, simple in construction, and bonding pad 1 is by even
Connect hole to be connected with bucket tooth pin, after work a period of time, after crown weares and teares, unclamp bolt 9, change crown 3, without all
Change whole bucket tooth, change simple and convenient, and reduce the cost of integral replacing bucket tooth, save material.
In order to prevent bucket tooth pin from encountering bolt head, affecting bucket tooth work, this utility model is arranged over sinking at described through hole
Head groove 10, bolt 9 is hexagon socket head cap screw, and described bolt head is arranged in countersunk recesses 10, will not encounter bucket tooth pin.
Blowpit 5 described in the utility model is gradually provided with reinforcement 11, increases bucket tooth intensity.
Blowpit 5 described in the utility model seamlessly transits with crown 3, reduces resistance.
On the same axis, described wearing layer 7 is that high alumina is blue or green for bonding pad 1 described in the utility model, working area 2 and crown 3
Layers of copper.
Technological means disclosed in this utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also
Including the technical scheme being made up of above technical characteristic combination in any.
