中文摘要 | 插秧機插植機構中,秧苗推出機構為重要組件,主要係由推出凸輪、彈簧、以及 推出桿等所組成。秧苗推出機構在操作中,秧苗推出時機關係植苗品質之良莠,此部份係由 凸輪控制。本文第一部份針對裕農牌插秧機秧苗推出機構之凸輪輪廓進行分析,分別推導凸 輪從動件之位移、速度與加速度數學表示式。第二部份利用三次仿線規劃設計凸輪曲線,使 秧苗推出桿在運動過程中所產生之加速度╱急衝度總和最小,同時維持準確之推苗時機。 |
英文摘要 | The seedling pushing mechanism is one of the important compoent sets of a rice transplanter. This mechanism usually consists of a cam, a spring and a pushing rod. The cam which dominates the timing for pushing rice seeding plays an important role in transplanting operation. In the first part of this study, the analysis of the cam profile of a Yu-Nung transpanter was undertaken. The displacement, velocity, and acceleration of the cam-follower was derived. In the second part, a cubic spline equation was modeled to synthesize the profile of the cam to minimize the acceleration/jerk of pushing rod while the precise time of pushing seeding is maintained. |
