Abstract: To solve problems of high energy consumption，low efficiency and single operation of traditional residual membrane recovery equipment，a multifunctional residual membrane removal machine was designed.The optimal design scheme and parameter of the machine were determined by studying design scheme of matching power selection，arrangement of curling rake teeth，suspension parameters，and overload protection device.In order to verify performance of the equipment，field experiments were carried out.Results showed that residual membrane removal machine could loosen，hold，collect and unload membrane in one operation，with an operation efficiency of 2.33 hm2/h and picking-up at 80% removing rate，without disturbing soil layer.It is easy to implement the work of seedbed ploughing before sowing，and soil fine crushing and leveling after operation by replacing individual parts.Residual membrane remover has characteristics of high removing rate，diversified functions，low production cost and high operation efficiency.
