Design of Straw Laying Corn Harvester

Design ideas and principles of straw laying corn harvester were elaborated.Structural design and technical features of the machine，transmission system and main working pads were introduced.A straw laying device was designed and its two-transmission way was given.This way can farthest simplify transmission path，reduce power dissipation and improve reliability of transmission.This machine can complete corn picking，transporting，skinning，header，straw chopped into pieces and laying etc.Actual field working test proved that the strew laying corn harvester met the national relevant standards，and also passed the appraisal of Shandong Agricultural Machinery Test Station and scientific and technological achievements .
