A type of press roller desorption structure which was designed based on the Motion Characteristic of earthworm segments was introduced in this paper.The transformation of segment for at head,middle and tail parts of earthworm were recorded by curve fitting analysis of the micro-image,and descripted by sine-type equation.Bionic desorption structure were designed based on the three sine-type equation and prepared by rubber and ultrahigh molecular weight polyethylene.Part of bionic desorption structure has been deformed with lower curvature to fit rigid roller body by press force,and the rest of desorption structure has been bulged by tension of rubber,thus the curvature of bionic desorption structure appeared cyclic variation which similar to the motion characteristic of earthworm segment.Experiment results shows that the soil adhesion of bionic desorption structure which were designed based on the segment at head,middle and tail parts of earthworm decreased 60.1%,52.5%,57.6%respectively.Kinematic analysis results shows that segment at head of earthworm produced the most significant curvature change which formed higher shear stress to the adhesion soil on the surface.
