摘要
针对黄淮海轮作区小麦玉米轮作机械化生产体系,优化出了既符合农学要求又符合机械化作业要求的基本种植规格。设计了2BYM-12型折叠式动力防堵免耕玉米播种机,该机具有独特的苗带清理及作业防拥堵功能、株距无级调节及其他关键部位作业监控功能、播种深度调节功能和作业仿形功能,适于大面积平整地块高效作业。采用了轻量化技术和液压折叠技术,便于田间转移和作业。在动力匹配和负载计算的基础上,利用ANSYS软件对2BYM-12型免耕播种机中间播种单元进行了有限元分析。结果表明,播种机的应力分布状况与实际情况一致,播种机整体受力符合设计要求。田间试验表明播种机作业性能达到了设计要求。
For the mechanization system of maize-wheat production in the north China plain,a basic planting specification was optimized which met the requirements of agricultural mechanized farming.The type 2BYM-12 folding and dynamic anti-blocking no-till maize planter had functions of seedling zone cleaning,dynamic anti-blocking,intelligent stepless adjustment to plant spacing,automatic testing farming quality and quantity of large scale precision seeder,adjustment to sowing depth,copying work and so on.Lightweight technology and hydraulic folding technology were adopted beneficial to agricultural machine field transfer and operation.Based on power matching calculation and load calculation,the type2BYM-12 no-till planter was analyzed with finite element method.The calculation indicated that the stress distribution of no-till planter was similar to the actual situation, and satisfied the design requirements.
