摘  要：
针对现有扎穴机构存在扎穴穴口大、入出土垂直度差等问题,设计了一种深施型液态施肥机非圆齿轮行星系扎穴机构。为使扎穴机构得到满足农艺要求的入出土垂直度,提出了一种基于Matlab GUI开发平台的非圆齿轮行星系扎穴机构反求设计与运动学仿真分析方法。通过微调静轨迹曲线上的少量型值点,得到了一组机构最佳优化参数,应用Pro/E软件建立扎穴机构模型,并利用ADAMS软件对其进行模拟仿真,得到喷肥针尖点运动轨迹曲线。试验台试验结果表明:穴口宽度为30.3 mm、穴距为221.9 mm,该扎穴机构能够满足喷肥针入出土垂直度好、穴口小的设计要求。

摘  要：
Aiming at the existing problems of big hole and bad verticality of picking hole mechanism,a kind of picking hole mechanism of non-circular gear planetary system for deep liquid fertilizer was designed. To make picking hole mechanism satisfy the agronomic required verticality when it gets into and out of the soil,the reverse design and kinematics simulation analysis of picking hole mechanism of non-circular gear planetary system were presented based on Matlab GUI development platform. Through the fine-tuning of a small amount of date points on static trajectories which were generated in the inverse design and kinematics simulation, a set of optimal parameters were obtained. The picking hole mechanism model was established by applying Pro / E software. And with the ADAMS software,the trajectory curves were got. Finally,this picking hole mechanism was tested on the test-bed,and the results showed that when the hole width was 30. 3 mm and the hole distance was 221. 9 mm,the proposed picking hole mechanism could meet the design requirement,that means,good verticality and small hole when it gets into and out of the soil.
