Abstract: A cleaner for corn residue film and root stubble was designed，in order to study and solve problem of residual mulch and root stubble difficult to recover and so on.Film picking and root digging device could dig corn root stubble，soil and residue film into transposition chain board.Eccentric shaft driven by front ground wheel makes transposition chain board vibrate，meanwhile，film conveyed on transposition chain board was picked up and cleaned into film collection box.Remaining soil and root stubble were crushed into double axis crushing mechanism.Cleaner for corn residue film and root stubble on ridge with working speed of 3～5 km/h and width of 1 100 mm.Corn stubble with 200 mm depth，soil and plastic film with 100 mm depth could be scooped up.Results of ANSYS analysis showed that strength of film and root shovel could meet requirements.The machine could finish cleaning of residual film and root stubble and crushing of stubble，and meet operation requirements.
