Further, described concave surface comprises cancave cambered surface and horizontal plane, and described cancave cambered surface is positioned at the one end near described Connection Block, and be bent downwardly towards described horizontal plane, described horizontal plane is positioned at the one end away from described Connection Block, connects with described cancave cambered surface.
Further, the horizontal length of described cancave cambered surface is the 1/4-1/2 of the length of described horizontal plane.
Further, the shape of described first reinforcing rib bottom surface matches with described concave surface, and the end face of described first reinforcing rib linearly extends upwardly to the other end of described crown from the forward position of described crown.
Further, described second reinforcing rib comprises reinforcing rib leading portion and reinforcing rib back segment, described reinforcing rib leading portion is bent upwards from the one end in close described crown forward position is curved, described reinforcing rib back segment is bent downwardly to the one end near described Connection Block top from the junction of described reinforcing rib leading portion is curved, and the bottom surface of described reinforcing rib leading portion and described reinforcing rib back segment and the sidewall of described Connection Block and described crown fit.
Further, the end face width of described reinforcing rib leading portion increases from the one end near described crown forward position gradually to the one end near described reinforcing rib back segment, and the end face width of described reinforcing rib back segment equals the maximum end face width of described reinforcing rib leading portion.
Further, the horizontal length of described reinforcing rib leading portion equals the horizontal length of described reinforcing rib back segment.
The advantage that the present invention has and good effect are:
1, crown top of the present invention is provided with concave surface, reduce the thickness of crown, improve the sharpness of crown, be more conducive to excavate, concave surface top is provided with many first reinforcing ribs, ensure that the intensity of crown, not easily bending or distortion, effectively increases the application life of bucket tooth under a larger impact force;
2, on the sidewall of bucket tooth, the second reinforcing rib is provided with, ensure that the bulk strength of bucket tooth, ensure that bucket tooth is not easy to wear, second reinforcing rib is thin near crown place, the setting that thickness increases gradually reduces resistance during excavation, reduce the friction of material and bucket tooth, be more conducive to still can normally work under larger excavation depth.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As Fig. 1, Fig. 2, shown in Fig. 3, the invention provides a kind of bucket tooth, comprise Connection Block 1, crown 2, described Connection Block 1 left and right sides wall is provided with counterbore 3, it is characterized in that: described crown 2 upper surface is provided with concave surface 4, described concave surface 4 extends to the forward position of described crown 2 from described Connection Block 1 and the junction of described crown 2, described concave surface 4 is provided with many first reinforcing ribs 5, described first reinforcing rib 5 extends to the other end of described concave surface 4 from one end of described concave surface 4, described Connection Block 1 with described crown about 2 sidewall are provided with the second reinforcing rib 6, described second reinforcing rib 6 and described Connection Block 1 and the one-body molded setting of described crown 2.
Further, described concave surface 4 comprises cancave cambered surface 41 and horizontal plane 42, and described cancave cambered surface 41 is positioned at the one end near described Connection Block 1, is bent downwardly towards described horizontal plane 42, described horizontal plane 42 is positioned at the one end away from described Connection Block 1, connects with described cancave cambered surface 41.The setting of concave surface 4 reduces the thickness of crown 2, improves the sharpness of crown 2, is more conducive to excavate.
Further, the horizontal length of described cancave cambered surface 41 is the 1/4-1/2 of the length of described horizontal plane 42.
Further, the shape of described first reinforcing rib 5 bottom surface matches with described concave surface 4, and the end face of described first reinforcing rib 5 linearly extends upwardly to the other end of described crown 2 from the forward position of described crown 2.The setting of the first reinforcing rib 5 ensure that the intensity of crown 2, and not easily bending or distortion, effectively increases the application life of bucket tooth under a larger impact force.
