垄膜玉米地表残膜及根茬清理机设计

针对覆膜玉米收获后残留地膜、根茬不易回收等问题，研究设计了一种残膜及根茬清理机。起膜起根装置将根茬、土壤及地膜铲起送入链板输送装置，前地轮驱动偏心轴使得链板输送装置产生振动，同时拾膜、脱膜装置将在链板上输送的地膜拾起并清理至集膜箱，剩余的土壤、根茬进入双轴粉碎机构粉碎。工作速度3～5 km/h，幅宽1 100 mm，可将200 mm深的玉米根茬和100 mm的土与地膜铲起，回收残膜的同时可对玉米根茬进行清理与粉碎，并对土壤进行疏松。有限元分析结果表明起膜起根铲强度满足要求。该机可完成残膜、根茬的清理及根茬的粉碎工作，满足作业要求。 

Design of Cleaner for Corn Residue Film and Root Stubble on Ridge

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.
