The cross section of the diversion trench is triangle.Preferably, the cross section of diversion trench is arranged to triangle, protecting
Demonstrate,prove in diversion trench on the premise of material normal movement, reduce contact area between material and water conservancy diversion groove sidewall, that is, reduce both it
Between rubbing action, improve the incision efficiency of bucket tooth.
Compared with prior art, the present invention have the following advantages and advantages：
1st, diversion trench of the invention causes bucket tooth madial wall quickly to cut material as the cushion space that the extruding force discharges
In matrix, accelerate material matrix loosening, facilitate the excavation and transhipment of material, wherein so-called material matrix refer to soil horizon,
The geologic structure such as concrete layer or lithosphere.And the depth of diversion trench extends along direction and is incremented by so that with bucket tooth
Deeply, the space that extruding force effect is discharged between bucket tooth madial wall and material matrix is stepped up, and is further improved under bucket tooth
Cut efficiency；
2nd, the crown that the present invention is obliquely installed causes the end of bucket tooth to have a high intensity and sharp keen incision inferius, at the same time
Incision resistance of the material matrix to bucket tooth can be reduced, while the material for roll upwards quickly moves in diversion trench；
3rd, the cross section of diversion trench is arranged to triangle by the present invention, is ensureing the premise of material normal movement in diversion trench
Under, reduce contact area between material and water conservancy diversion groove sidewall, that is, reduce rubbing action between the two, improve the incision effect of bucket tooth
Rate.
