西北旱区大豆玉米复合种植联合播种机的设计与试验OA北大核心CSTPCD
Design and experiment of a combined planter for soybean and corn compound planting in Northwest arid area
针对西北旱区大豆玉米复合种植机具短缺、机械化程度低等问题,设计西北旱区大豆玉米复合种植联合播种机.该机由旋耕装置、起垄装置、覆土装置、施肥装置、播种装置及机架等组成,能够实现旋耕、起垄、施肥、双幅覆膜覆土、镇压及播种等多个作业过程.对播种机关键部件进行设计与分析,利用离散元模型对覆土过程进行模拟仿真,分析覆土过程中膜边膜上覆土均匀性;采用DEM-MBD对大豆玉米播种装置耦合仿真,分析大豆玉米播种装置播种均匀性.仿真结果表明:1)土壤因跳跃和泼撒而…查看全部>>
In response to the shortage of soybean and corn compound planting equipment and low mechanization level in the Northwest arid area,a soybean and corn compound planting combined seeder was designed.This machine is composed of one rotary tillage device,one ridging device,one soil covering device,one fertilization device,one frame,and one seeding device.It can achieve multiple operational processes such as rotary tillage,ridging,fertilization,double film mulchi…查看全部>>
