摘  要：
针对吊篮式钵苗移栽机膜上移栽易撕膜的问题,设计了一种鸭嘴式钵苗移栽机。建立了该机栽植机构的运动数学模型,并以此为依据在ADAMS中对栽植机构进行了参数化建模。利用参数化模型,分析了主要参数对机构运动特性的影响。在保证钵苗直立度较高的同时,以产生的穴口尽量小为优化目标,获得了一组最佳参数组合。此组合下,形成的穴口大小约为1.8 mm,鸭嘴栽苗后的运动轨迹垂直度较高,满足膜上移栽钵苗直立度高、不撕膜的农艺要求。

摘  要：
During the up-film transplanting for dibble-type transplanters,the mulch film could be easily dilaceraded and scraped.Aiming at this problem,a pot seedling transplanter in duck-beak style was designed while the working principle of it was expounded.The motion mathematical model of its planting mechanism was established.And then,parametric modeling for the planting mechanism based on the model was completed in ADAMS.The influences over the mechanism motion characteristic by some important parameters were analyzed by using the parametric model.In addition,the cave value which formed by the distance between two intersections points of the duck-beak trajectory and ridge line as possible as small was taken as the optimization objective,while the higher upright degree of seedling was ensured.Meanwhile,the optimal parameter combination of planting mechanism was obtained.With it,the cave value was 1.8 mm and the verticality of duck-beak trajectory after transplanting seedlings was higher,and then the demands of up-film transplanting could be met,namely higher upright degree of seedling and without dilacerating films.
