摘　　要：介绍了一种组合气吸式膜上精量穴播机,分析了气吸式精量排种器与膜上鸭嘴式穴播轮的同步投种比,对气吸式精量排种器真空选种的可靠性进行了计算与分析,并通过仿形机构实现了一体化铺膜与精量穴播的同步作业。应用Pro/E软件进行虚拟样机的运动学仿真分析,建立了穴播鸭嘴的运动方程。试制样机后进行了田间试验,对膜上精量穴播的质量进行了评估与测量。A composite membrane gas absorption type precise dibbling machine is introduced,a suction type precise metering device is analyzed with membrane duck- billed dibbling round than synchronous shot of gas suction precise metering device of the reliability of the vacuum seed selection for the theoretical calculation and analysis,and a profiling mechanism is used to realize the integration of membrane and precise dibbling synchronous operation. Using Pro /E software for kinematics simulation analysis of virtual prototype,the dibbling duck mouth movement equation is established. Field experiment is done after prototype development,with the quality of precise dibbling on the film evaluated and measured.
