Description
Technical field
The utility model belongs to engineering machinery field, relates to excavator equipment, is specifically related to a kind of excavator bucket teeth.
Background technology
Excavator bucket teeth is one of excavator equipment important spare part, generally comprise the bucket tooth and the toothholder that link to each other by connector, toothholder then is fixedly mounted on the forefront of power shovel, because the excavator working environment is quite abominable, excavator bucket teeth directly bumps with the construction object during construction, and the construction object is often as hard as marble, cause excavator bucket teeth constantly to be subject to many-sided powerful anti-force effect, again because the junction of bucket tooth and toothholder is maximum position, assembling slit or the transmission maincenter of various power, therefore under the powerful anti-force effect of many-side, rocking very easily appears in this position of excavator bucket teeth, produce wearing and tearing once rocking, the larger then shaking amplitude in the slit of more wearing and tearing is just larger, and the shaking amplitude galling is just more severe, until damage, even some damages rear also inconvenient disassembling, assembling and replacing.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, proposed a kind of not fragile, and the excavator bucket teeth of easy accessibility.
The purpose of this utility model can realize by following technical proposal: a kind of excavator bucket teeth, comprise the bucket tooth and the toothholder that link to each other by connector, described bucket tooth afterbody is installation portion, it is characterized in that, described toothholder front end is provided with wedge shaped projection, described installation portion is provided with the cavity that is complementary with wedge shaped projection, described cavity floor middle part is provided with projection, described cavity accent place offers up and down symmetrically arranged breach, described wedge shaped projection afterbody is provided with the fixture block and the described fixture block that are complementary with breach and is connected in the above-mentioned breach, and described wedge shaped projection front end face is provided with the groove that is complementary with projection.This design, the internal chamber wall of the external surface of wedge shaped projection and cavity is fitted on the one hand, having eliminated the gap can rock in corresponding minimizing, add cooperating of the clamping of fixture block and breach and projection and groove, may occur when having overcome the excavator bucket teeth construction week make progress rock, assembling between bucket tooth and the toothholder can become very easy on the other hand, and makes bucket tooth and toothholder form integral body, also is conducive to quick conduction and the evacuation of various power.
In above-mentioned a kind of excavator bucket teeth, described bucket tooth one work plane is provided with convex shoulder, and described convex shoulder one end is connected with crown, and the other end links to each other with installation portion, the described convex shoulder other end extends to the installation portion medium position, and the height of convex shoulder raises gradually from crown end to installation portion end.This structure not only makes bucket tooth strengthen impact resistance, it is more hard that bucket tooth becomes, and reaction force moment that the construction object gives bucket tooth evacuate by the connecting portion that convex shoulder conducts to bucket tooth and toothholder, convex shoulder also can corresponding reduction resistance when object is constructed in collision simultaneously.
In above-mentioned a kind of excavator bucket teeth, the tail end on described bucket tooth front part sides limit is provided with cancave cambered surface and arc transition to the installation portion side.When this design made bucket tooth work, the object of can deeply constructing easily reduced the resistance that the construction object gives.
In above-mentioned a kind of excavator bucket teeth, described crown is provided with the first tangent plane that is connected with convex shoulder formation obtuse angle and the second tangent plane and the 3rd tangent plane that is connected with formation obtuse angle, bucket tooth front part sides limit.This structure makes the head of bucket tooth not only have sharp one side, and wear resistant and impact resistant.
In above-mentioned a kind of excavator bucket teeth, described another work plane middle part is provided with the buffer area of concave arc shape.This structure makes bucket tooth in the course of the work, and the construction object Yan Huding that piles up at the bucket tooth work plane evacuates to both sides, reduces the suffered resistance of work plane.
In above-mentioned a kind of excavator bucket teeth, described connector is for using latch.Not only the easy and firm locking effect of dismounting is excellent for this structure.
Compared with prior art, after the utility model adopted said structure, not only dismounting was easy, and makes bucket tooth and toothholder be assembled into integral body, had overcome because the gap produces to rock the long-term puzzlement that final appearance damages.

The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Such as Fig. 1, Fig. 5 and shown in Figure 6, the utility model comprises bucket tooth 1 and the toothholder 2 that links to each other by connector, be provided with wedge shaped projection 13 at toothholder 2 front ends, be provided with the cavity 4 that is complementary with wedge shaped projection 13 at bucket tooth 1 afterbody, be provided with projection 3 at middle part, cavity 4 bottom surfaces, be provided with the groove 17 that is complementary with projection 3 at wedge shaped projection 13 front end faces, and projection 3 inserts in the groove 17, offer up and down symmetrically arranged breach 15 at cavity 4 accent places, be provided with the fixture block 16 that is complementary with breach 15 at wedge shaped projection 13 afterbodys, fixture block 16 is connected in the breach 15.This design, the internal chamber wall of the external surface of wedge shaped projection 13 and cavity 4 is fitted on the one hand, having eliminated the gap can rock in corresponding minimizing, add cooperating of the clamping of fixture block 16 and breach 15 and projection 3 and groove 17, may occur when having overcome excavator bucket teeth 1 construction week make progress rock, assembling between bucket tooth 1 and the toothholder 2 can become very easy on the other hand, and it is whole that bucket tooth 1 and toothholder 2 are formed, and also is conducive to quick conduction and the evacuation of various power.
Such as Fig. 1, Fig. 2 and shown in Figure 3, be provided with convex shoulder 5 at bucket tooth 1 one work planes, convex shoulder 5 one ends are connected with crown 14, and the other end extends to installation portion 12 medium positions and installation portion 12 is solidly fixed, and the height of convex shoulder 5 raises gradually from crown 14 ends to installation portion 12 ends.This structure not only makes bucket tooth 1 strengthen impact resistance, it is more hard that bucket tooth 1 becomes, and construction object reaction force moment of giving bucket tooth 1 conduct to bucket tooth 1 by convex shoulder 5 and evacuate with the connecting portion of toothholder 2, convex shoulder 5 also can corresponding reduction resistance when collision construction object simultaneously.
