摘　　要：为了研究播种装置投种机理,判别稻种的投种速度、落种高度以及翻版角速度对稻种投种过程中的影响,通过仿真获得了稻种的速度与时间、垂直位移与速度以及翻板角速度与速度的变化规律。在与仿真条件相同的情况下,利用高速摄像技术对上述3种情况进行在线拍摄,并获得了这3种变化关系的曲线图。通过试验结果与理论结果的对比分析,得出投种过程中稻种的运动规律主要受翻板角速度、翻板长度、翻板质量及稻种质量等参数的影响—其运动速度随位移的增加而呈递增的趋势。由此为判别稻种的投种速度、落种高度以及翻板角速度对稻种投种过程中的影响提供理论依据。In order to study the seeding device investment mechanism , discriminant rice throwing velocity , drop height and angular velocity of a cast replica of rice , this paper obtained the variation of speed and time , rice vertical displacement and speed and tilting angle and velocity by simulation , and the simulation under the same conditions case , using the high-speed camera technology for online on the three image , and obtained the curves of these three changes , analysis, by comparing the test results with the theoretical results , movement for rice process is mainly affected by the tilting angular velocity , turning plate length , plate over the rice quality quality , parameters such as the velocity , displacement increased trend , so as to distinguish rice throwing velocity , drop height and plate turning angular velocity on the investment effects of rice in the process of providing the theory basis .
