Technical field
This utility model belongs to excavation machine part technical field, more particularly to a kind of excavator bucket tooth.
Background technology
Excavator bucket teeth is the vitals on excavator, is consumable accessory, the Dipper Teeth being made up of toothholder and crown,
Force analysis bucket tooth work surface contacts with thing is mined, different in a complete mining process its stress of working stage
Situation is different, crown position first contacting material surface when, due to speed, bucket tooth nose part be subject to it is stronger impact,
If the low intensity of bucket tooth, it will produce plastic deformation in tip, with the increasing of excavating depth, bucket tooth stressing conditions can change
Become, when bucket tooth cuts material, bucket tooth occurs relative motion with material, produces very big forward extrusion power on surface, so as in bucket
Larger frictional force is produced between tooth work surface and material, if material is harder rock block, concrete etc., frictional force will be
Very big, the result of this process repeated action produces different degrees of surface abrasion in bucket tooth work surface, and then produces depth
Larger ditch dug with a plow, affects the service life of bucket tooth.
The conventional bucket tooth life-span is very short, changes relatively frequently, not only have impact on work efficiency, and waste substantial amounts of original
Material, common bucket tooth wear no resistance, and production technology is also poor, high cost, the difficult popularization of comparison, and power consumption is also than larger, work effect
Rate is low, in order to improve work efficiency, can only Jing often change bucket tooth.
The content of the invention

Can be strong, long service life, high working efficiency, the excavator bucket tooth of production and application low cost.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：
Design on a kind of excavator bucket tooth, including the crown and bucket tooth main body set by bucket tooth main body, bucket tooth main body lower end
The set connecting portion in end, the end face of connecting portion are provided with installation cavity, and the surface of connecting portion is transversely provided with bearing pin installation through-hole, described
Bucket tooth main body and crown are cone structure, and set connecting portion is column structure, and wherein bucket tooth body surfaces ring is provided with
Multiple longitudinal arc splitter boxs, the junction of adjacent two longitudinal arc splitter boxs form teeth portion, are laterally set along teeth portion from top to bottom
There are multiple reinforcements, the bucket tooth main body, crown are provided with spur block, and the connecting portion is provided with protection projection.
Preferably, in above-mentioned excavator bucket tooth, the crown surface is provided with net-shaped protective cover.
Preferably, in above-mentioned excavator bucket tooth, longitudinal arc groove is that ring is uniform along bucket tooth body surfaces.
Preferably, in above-mentioned excavator bucket tooth, the bucket tooth main body outer rim is provided with overcoat.
Preferably, in above-mentioned excavator bucket tooth, the bucket tooth is steel alloy material.
The beneficial effect of technical solutions of the utility model is：
1st, contained by this utility model excavator bucket tooth, bucket tooth main body and crown are both designed as cone structure, make bucket tooth exist
During excavation, increase destruction of the bucket tooth to soil, make bucket tooth easily insert soil；The setting purpose of arc splitter box is to make bucket
Tooth when excavating, discharge from both sides, reduces the resistance of bucket tooth by soil or stone, protects the setting of block effectively to prevent hard thing from damaging
Bad bucket tooth.
2nd, the setting of reinforcement contained by this utility model, makes bucket tooth more firm and durable；Spur block, protection projection set
Put, it is therefore an objective to prevent bucket tooth from being damaged by stone during excavation, the service life of the setting effective protection bucket tooth of overcoat,
Make which more wear-resistant.
3rd, additionally, the setting of this utility model net-shaped protective cover, can be with the service life of effective protection bucket tooth so as to more
It is durable.Overcoat is set, can effectively prevent hard thing from damaging bucket tooth；Bucket tooth is steel alloy material so that component itself has
The characteristic such as standby high intensity, high tenacity, wear-resisting, can improve integrally-built service life.
4th, to sum up, this utility model anti-wear performance is strong, and consume energy low, long service life, due to significantly reducing replacing bucket tooth
Number of times, thus high working efficiency, production and application low cost, it is easy to promotion and implementation.
