摘    要:对2BQM-2型气吸式精量铺膜播种机的膜上开穴、取种、投种过程及其工作机理进行了分析,建立了种子运动轨迹的数学模型,在此基础上运用计算机仿真技术,动态模拟了膜上穴播的工作过程,找出了机组前进速度、投种角、接种漏斗偏置角变化时对种子投种精确度的影响规律,优化了相关设计参数,可为同类型精播装置的深入研究提供参考

关 键 词:计算机仿真  气吸式播种机  铺膜播种机  排种装置

Abstract:An analysis of the process of punching holes on the plastic film, grasping at the seed through suction holes, dropping off the seed and the operation mechanism of the 2BQM-2 model plastic film mulch pneumatic precision planter is carried out and a mathematical model for seed motional locus is established based on which the operation process for plastic film mulch dibbling function is simulated dynamically by use of computer simulation technology, the influence of the change of implement forward speed, seed drop off angle and the bias angle of seed receiving funnel on the seed metering accuracy is found out and the relevant parameters are optimized. The results of this research can be taken as a reference for the design of similar implements.
Keywords:computerized simulation  pneumatic planter  plastic film mulch planter  seed metering device
