摘要:
本文利用PRO/E和ADAMS建立了外槽轮式排种器的电控运动仿真模型，并设定相关约束与运动函数，对虚拟样机进行了动态仿真。对电控外槽轮式排种器的运动进行了设计，其中包括筛板对种子筛选的旋转运动，外槽轮式排种器槽轮与阻塞轮轴向变速移动与其同排种轴的变速转动。并使用霍尔元件采集数据，使用单片机处理数据并发射信号控制外槽轮式排种器槽轮与阻塞轮的有效工作长度与转速来实现对排种器播量的控制。电控外槽轮式排种器能够直接根据机具前进速度调节播量，提高对环境的适应性。
The virtual prototype model of Electronic Control External Groove Wheel Device has been estab-lished by using PRO/E and ADAMS and the relevant constraints and movement functions have been set. The movement of Electronic Control External Groove Wheel Device has been designed and analyzed, including the movement of sieve plate rotation , the movement of geneva wheel and blocking shaft with variable lateral movement and variable speed rotation. Using hall element to collect data, processing data and transmitting signal through the MCU that controls the effective working length and rotational speed of geneva wheel and blocking shaft. Finally, the device can realize control of the sowing quantity.
