Bionics Design of Stubble Blade Based on the Digging Claw of Mole Cricket

Mole cricket is one of soil animals. By studying the toe body, toe angle and toe surface morphology of the mole cricket mining claw, taking example by the size of commonly used triangular sawtooth, five L-type stubble-cleaning blades with different tooth throat angle were bionic designed. The result is shown that the blade with –22.5° tooth throat angle is the optimal by simulating using solidworks software.
