In order to deeply study the leaf-stripping principle for corn stalk, the hexagon-enveloping leaf-stripping experimental device was designed. To achieve higher leaf-stripping percent and provide important references for the separation equipment for corn stalk, it is necessary to find out the laws of leaf-stripping of such mechanism and to select the main infl uencing factors of separation performance from a number of factors. Through the study on hexagon-enveloping leaf-stripping mechanism for corn stalks, the leafstripping principle of such mechanism was more clear, and the optimization of structural and kinematic parameters achieved by the experiment whose infl uencing factors were the four selected ones(feeding speed, rotary speed of leaf-stripping roll, clearance and included angle between two leaf-stripping plates) could be directly applied to the development of efficient rind-pith or leaf-stripping separation for corn stalks.
