Abstract
The utility model provides bucket teeth which comprise a tooth seat and a tooth cover, wherein the tooth cover is arranged at the front end of the tooth seat in a sleeved mode, a through hole penetrates through the tooth seat, and two side walls of the tooth cover are provided with installation holes which are coaxial with the through hole and smaller than the through hole in diameter. The tooth seat and the tooth cover are connected through two pins, each pin is provided with a pin body and a head which is larger than the pin body in diameter, the two pins are respectively arranged at two ends of the through hole, the pin bodies are inserted into the installations holes, and a compression spring is mounted between the two pins. The bucket teeth overcome shortcomings of an existing bucket teeth structure, and is simple in structure, easy to machine and manufacture, and convenient and rapid when the bucket teeth need to be replaced in urgent construction and the pins fall off or the bucket teeth are abraded; when an excavator excavates hard materials, a rubber mat can directly play a role in shock absorption, impact action on a hydraulic system, electrical equipment and even the whole structure is reduced, a role of protection is achieved, and service life of the excavator is prolonged.
Description
Technical field
The utility model relates to a kind of excavator parts, particularly a kind of bucket tooth.
Background technology
Present bucket tooth all adopts the alligator with jump ring to connect between toothholder and tooth cover, this connecting mode requires between toothholder and the tooth cover certain interval is arranged, and pilot hole has the surplus of centering when selling to guarantee to fill, if very close to each other, assembling is just difficult, and processing and fabricating will reach suitable precision.Under the effect of impact force, produce between toothholder and the tooth cover and impact and friction, produce high temperature, the hardness of material and toughness are reduced, cause very quick-wearing of crown, the toothholder fracture that is hit, because repeatedly impact, alligator and jump ring also produce fatigue failure easily in addition.
The utility model content
The technical problem that (one) will solve
It is firm that the technical problems to be solved in the utility model provides a kind of installation, the bucket tooth of good impact resistant effect.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of bucket tooth, comprise toothholder 1 and tooth cover 2, described tooth cover 2 is set in described toothholder 1 front end, be penetrated with through hole 4 on the described toothholder 1, described tooth overlaps 2 two sides and offers installing hole 5, described installing hole 5 is coaxial with described through hole 4, the aperture of described through hole 4 is greater than the aperture of described installing hole 5, and described toothholder 1 is connected 2 by 6 connections of two pins with tooth, and described pin 6 has pin body and head, described head diameter is greater than described pin body diameter, described two pins 6 are located at respectively described through hole 4 two ends, and described pin body inserts in the described installing hole 5, between described two pins 6 Compress Spring 8 are installed.
Further, be arranged with guide 7 on the described pin 6, described guide 7 one ends prop up the head of described pin 6, and described guide 7 other ends prop up described tooth and overlap 2 inwalls.
Further, be provided with rubber pad 3 at the bonding surface place of described toothholder 1 and tooth cover 2.
(3) beneficial effect
The utility model bucket tooth; eliminated the deficiency of existing Tooth structure; simple in structure, be easy to processing and manufacturing, pin comes off or bucket tooth wearing and tearing when needing to change bucket tooth promptly constructing, run into; convenient and swift; when excavating hard material, rubber pad can directly play cushioning effect, reduces to impact the percussion to hydraulic system, electrical equipment and even complete machine structure; play a protective role, prolong the application life of excavator.
Description of drawings
Fig. 1 is the sectional view of the utility model bucket tooth;
Fig. 2 is A-A sectional view among Fig. 1.
The specific embodiment
Consult Fig. 1 and Fig. 2, the utility model provides a kind of bucket tooth, comprise toothholder 1, tooth cover 2 and pin 6, tooth cover 2 is set in toothholder 1 front end, be penetrated with through hole 4 on the toothholder 1, tooth overlaps 2 two sides and offers installing hole 5, installing hole 5 is coaxial with through hole 4, the aperture of through hole 4 is greater than the aperture of installing hole 5, and toothholder 1 is connected 2 by 6 connections of two pins with tooth, and pin 6 has pin body and head, head diameter is greater than pin body diameter, two pins 6 are located at respectively through hole 4 two ends, and the pin body inserts in the installing hole 5, between two pins 6 Compress Spring 8 is installed, be arranged with guide 7 on the pin 6, guide 7 one ends prop up the head of pin 6, and the other end props up tooth and overlaps 2 inwalls, are provided with rubber pad 3 at the bonding surface place of toothholder 1 and tooth cover 2.
When mounted, in the through hole 4 of the toothholder 1 of first Compress Spring being packed into, cover is had pack into the through hole two ends of toothholder 1 of the pin 6 of guide 7, two ends are compressed simultaneously, until the tooth cover of can packing into again.Behind the tooth of packing into the cover, Compress Spring ejects pin from the installing hole of tooth cover, Compress Spring keeps certain pretightning force, guarantee that pin can not make the tooth cover come off from toothholder when being subjected to lateral compression power, because guide is pinned by the tooth cover, guide has withstood pin, guarantees that pin can not come off from installing hole, thereby has realized auto-lock function.The utility model bucket tooth; eliminated the deficiency of existing Tooth structure; simple in structure, be easy to processing and manufacturing, pin comes off or bucket tooth wearing and tearing when needing to change bucket tooth promptly constructing, run into; convenient and swift; when excavating hard material, rubber pad can directly play cushioning effect, reduces to impact the percussion to hydraulic system, electrical equipment and even complete machine structure; play a protective role, prolong the application life of excavator.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
