针对国内汉麻收获打捆作业的需求,开展了自走式汉麻打捆机的研究工作,研制出汉麻专用自走式汉麻打捆机.样机主要由自走式底盘、捡拾机构、打结机构、送绳机构以及行车系统、动力系统等组成.样机设计最小离地间隙大于20 cm,底盘平台高度小于100 cm,工作行车速度为6~10 km/h,工作效率可达10公顷/台班.经过两年的研究改进与试验,样机可完成捡拾、输送、打捆及脱捆动作,达到设计要求并可满足生产作业需求.针对样机存在的问题,应从麻杆缠绕、零部件公差配合及型号选择等方面进一步改进.该机有较大市场需求和应用前景.%Aiming at the needs of domestic China-hemp harvest baling work,the author has carried out the research of the self-propelled China-hemp baling machine and developed a dedicated self-propelled China-hemp baling machine.The model machine is mainly composed of self-propelled chas-sis,pick-up mechanism,knotting mechanism,rope -feeding mechanism,running system and power system.The minimum clearance of model machine is greater than 20 cm,the chassis platform height be-ing less than 100 cm,the working speed reaching 6-10 km/h,and the efficiency of operation up to 10 hectares per machine -team.After two years of exploratory improvement and test,the model machine has achieved pick-up,conveying,baling and un-baling movements which has met the design require-ment and can satisfy the production operation needs.Aiming at problems with the model machine,it should be improved from the aspects of hemp rod,machine parts tolerance control and model selection. The model machine has great potential for larger market demand and application.
