摘　　要：针对现有烟秆清理机存在效率低、适应性差等问题,设计一种新型田间烟秆清理机械。该机采用自走式机型,由夹持拔秆装置、松土铲等关键部件组成,可一次性完成双垄的松土、拔秆、收集等一系列清理作业,并对关键部件进行设计。通过EDEM仿真试验确定了松土铲扰动效果与耕作阻力的最优参数:入土深度20mm、铲头入土角24°和铲翼张角60°。田间单因素试验表明,影响烟秆拔净率的因素为机械作业速度、夹持带传输速度和夹持高度。田间多因素试验确定的机械最优工作参数为清理机械作业速度0.4m/s、夹持带传输速度0.58m/s、夹持高度0.43m,此条件下烟秆拔净率≥85%。Aiming at problems of low efficiency and poor adaptability of existing tobacco straw cleaning machines,a new type of tobacco straw cleaning machine in field was designed.The machine adopted self-propelled model,composed of key components such as gripper straw pulling device and shovel,which could complete a series of cleaning operations such as soil loosening,straw pulling and collection in double ridges at one time.Key components were designed.Optimal parameters for disturbance effect and tillage resistance of soil loosening shovel were determined through EDEM simulation experiments,including a depth of 20 mm,an angle of 24°for shovel head to enter soil,and a blade angle of 60°.Field single factor experiments showed that factors affecting tobacco straw removal rate were mechanical forward speed,clamping belt transmission speed,and clamping height,respectively.Optimal working parameters of machinery determined by field multifactor experiment were forward speed of cleaning machinery of 0.4 m/s,transmission speed of clamping belt of 0.58 m/s,clamping height of 0.43 m,and tobacco straw removal rate of≥85%.
