Abstract:During the working process of press roller, the deficiencies in the soil adhesion and the large slip rate on the profiling elastic press roller are existed. Based on the flexible geometry features of the typical soil animal body surface, the reducing soil adhesion and anti-slip structure were designed to solve the problem. The structure consists of rubber bulges, which are fixed by the existing bionic rib structure. This structure has the advantages of less soil adhesion, lower slip rate, more uniform pressure distribution and better soil crushing effect. The movement process of the reducing soil adhesion and anti-slip structure was researched by using theoretical calculation and kinematics analysis, the characteristic equation of rubber bulges and the value ranges of bulge height and rib height were obtained. The orthogonal combination experiments of three factors and three levels were designed and performed. The results showed that the primacy sequence of the experiment factors influencing soil adhesion was: rubber bulge height (H), rib height (L), total loads (F) and the primacy sequence of the experiment factors influencing slip rate was: rib height, rubber bulge height and total loads. Optimal levels of the experiment factors influencing soil adhesion and slip rate were F of 450.0N, H of 13.9mm, L of 15.1mm. At the same time, verification tests and comparison tests were conducted in the field. The results showed the soil adhesion quality was 39.2g, the slip rate was 3.89%, compared with the roller without the reducing soil adhesion and anti-slip structure, the soil adhesion quality was reduced by 60.1% and the slip rate was reduced by 54.3%.
