Detailed Description

An embodiment of the present invention will be described in detail with reference to fig. 1-3, but it should be understood that the scope of the present invention is not limited by the embodiment.

As shown in fig. 1-3, an embodiment of the present invention provides an excavator tooth, including: excavation end 2 and location end 1, excavation end 2 are located the front portion of location end 1, excavation end 2 and location end 1 integrated into one piece, and location end 1 is connected with the excavator fill, and its characterized in that, excavation end 2 includes: the positioning end 1 comprises an upper side 21, a lower side 22, a left front side 23, a right front side 24, a left rear side 25, a right rear side 26 and a rear side, wherein the rear side and the positioning end 1 are integrally formed, the upper side 21 is in a diamond shape, the rest sides are in a triangular shape, the front end point of a long diagonal of the diamond shape shares a first vertex 27 with the triangular shape of the lower side 22, the left front side 23 and the right front side 24, the first vertex 27 is the front vertex of the lower side, the rear end point of the long diagonal of the diamond shape shares a second vertex 28 with the triangular shape of the left rear side 25, the right rear side 26 and the rear side, the height of the second vertex 28 is flush with the height of the positioning end 1, and the longitudinal section of the digging end 2 along.

Go up side 21, downside 22, left front 23 and right front 24 and first summit 27 and make the front end of excavation end 2 constitute the rectangular pyramid, go up side 21 and be the rhombus, make the front end rectangular pyramid of excavation end 2 can wedge soil into relatively fast, destroy the soil top layer, reduce the resistance that the scraper bowl cut soil, reduce the wear rate of bucket tooth, improve the wholeness ability and the excavator work efficiency of bucket tooth, increase of service life, effectual saving cost.

The longitudinal section of the positioning end 1 is isosceles trapezoid, and the structure is stable.

The rear side of the positioning end 1 is provided with a positioning end face 13, a positioning groove 12 is arranged forwards along the positioning end face 13 in the positioning end 1, the positioning groove 12 is matched with a positioning column on the excavator bucket, two positioning through holes 11 are symmetrically arranged on the left side and the right side of the positioning groove 12, and the two positioning through holes 11 are respectively communicated with the positioning groove 12.

The positioning through hole 11 is a threaded hole, and a positioning bolt penetrates through the threaded hole, the positioning groove 12 and a positioning hole in the positioning column of the excavator bucket to connect the positioning end with the excavator bucket.

Positioning hole 11 is the counter bore, and the counter bore makes the both ends of bolt and the left and right sides face looks parallel and level of location end, reduces the resistance of bolt to soil, reduces the wearing and tearing to the bolt both ends simultaneously.
