Common manganese steel forging, its shortcoming is head bald head easy to wear, yielding, easy, the life-span is short, generally use less than 3 working days, needs
Frequently to change bucket tooth, waste of manpower, material resources, financial resources, in order to strengthen the mechanical performance of bucket tooth, improve efficiency, research worker is led to
Cross use wearability, good toughness material to overcome existing defect, but cost is high, be difficult to popularization.
Summary of the invention
For solving the problems referred to above, the utility model discloses a kind of excavator wear-resistant bucket tooth, crown and tooth status are from, structure
Simply, only change crown, save material, reduce cost.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of excavator wear-resistant bucket tooth, it is characterised in that: include that connecting portion, work portion, wearing piece, described work portion include
Tooth body, crown, described connecting portion is the hollow inverted trapezoidal structure of upper opening, and connecting portion side is provided with connecting hole, described tooth body
Being arranged between connecting portion and crown, described crown is smaller in size than tooth body, and described crown is solid frustum cone structure, sets in the middle of crown
Fluted, crown rear end is provided with the countersunk screw holes with texturearunaperpendicular, and described wearing piece is anchor type, and the middle part of wearing piece is arranged
In groove, other positions of wearing piece are fixed on outside crown, and work portion size from top to bottom is gradually reduced, wearing piece and tooth
Point is internal to be bolted, and is provided with wear-resisting plug at the countersunk head of countersunk screw holes.
As a kind of improvement of the present utility model, described bolt is hexagon socket head cap screw.
As a kind of improvement of the present utility model, before and after described tooth body, two ends, face are provided with blowpit.
As a kind of improvement of the present utility model, described tooth body seamlessly transits outside wearing piece.
As a kind of improvement of the present utility model, described connecting portion, tooth body and crown are on the same axis.
The beneficial effects of the utility model are:
A kind of excavator wear-resistant bucket tooth described in the utility model, at crown outer wrap wearing layer, simple in construction, when resistance to
After mill part abrasion, unclamp bolt, change crown, without all changing whole bucket tooth, change simple and convenient, save material,
Reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is right view of the present utility model.
Reference numerals list:
1, connecting portion, 2, tooth body, 3, crown, 4, wearing piece, 5, connecting hole, 6, groove, 7, countersunk screw holes, 8, bolt, 9,
Wear-resisting plug, 10, blowpit, 11, at the countersunk head of countersunk screw holes.
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

Be directed towards or away from the direction of particular elements geometric center.
As it can be seen, a kind of excavator wear-resistant bucket tooth described in the utility model, including connecting portion 1, work portion, wearing piece
4, described work portion includes that tooth body 2, crown 3, described connecting portion 1 are the hollow inverted trapezoidal structure of upper opening, connecting portion 1 side
Being provided with connecting hole 5, described tooth body 2 is arranged between connecting portion and crown, and described crown 3 is smaller in size than tooth body, and described crown 3 is
Solid frustum cone structure, is provided with groove 6 in the middle of crown 3, and crown 3 rear end is provided with the countersunk screw holes 7 vertical with groove 6, described wear-resisting
Part 4 is in anchor type, and the middle part of wearing piece 4 is arranged in groove 6, and other positions of wearing piece 4 are fixed on outside crown 3, work
Making portion's size from top to bottom to be gradually reduced, wearing piece 4 is internal with crown 3 to be connected by bolt 8, and at the countersunk head of countersunk screw holes, 11 set
There is wear-resisting plug 9.
A kind of excavator wear-resistant bucket tooth described in the utility model, uses nickelic antifriction alloy to forge and forms, outside crown
The wearing layer 4 of portion's parcel is Aluminum Bronze layer, and intensity is high, and wearability is good, simple in construction, and connecting portion 1 is by connecting hole 5 and bucket tooth
Pin connects, and after work a period of time, after wearing piece 4 abrasion outside crown, takes out wear-resisting plug 9, unclamps bolt 10, change resistance to
Mill part 4, without all changing whole bucket tooth, changes simple and convenient, saves material, reduce cost.
Bolt 8 described in the utility model is hexagon socket head cap screw, in described bolt head is arranged at the countersunk head of countersunk screw holes 11,
Will not damage, it is convenient to change.
Before and after tooth body 2 described in the utility model, two ends, face are provided with blowpit 10, smoothed outside tooth body 2 and wearing piece 4
Cross, be provided to reduce working resistance, increase the service life.
On the same axis, the transmission of power is more smooth and easy for connecting portion 1 described in the utility model, tooth body 2 and crown 3, improves
Work efficiency.
Technological means disclosed in this utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also
