自走式烟苗移栽机栽植器的研究与设计

摘要

栽植器是自走式移栽机的核心部件，其性能决定了烟苗落地时的直立度以及烟苗入土深度。比较国内现有几种类型栽植器的优缺点后，设计出一种新型的侧置四连杆旋转鸭嘴式烟苗栽植器，并进行样机田间试验，栽植效果较好。%The planting device is the key component of the self-propelled transplanter, while its performance determines the tobacco seedling landed upright degree and depth of tobacco seedlings. A duckbill type tobacco seedling transplanter of four connecting rod ro-tating style was designed based on the comparisons of the advantages and disadvantages of existing domestic planting apparatuses. Proto-type field experiment shows that the planting effect of this new device is good.
