为解决高速水稻插秧机在农田作业时,插秧盘随水田表面横向起伏导致秧苗插植深度不一致的问题,开展了基于插秧机插植部倾角检测的秧苗插深自适应调节系统的研究与开发。通过角度位移传感器实时检测两浮板相对位置的变化,由数据采集及插深控制单元控制步进电机装置输出,通过动力传输机构来改变整个秧盘的横向侧倾角度,使秧盘与浮板保持一个稳定的相对位置关系,从而达到稳定插秧深度的目的。插秧机仿真实验平台上的静动态实验分析表明,该系统具有良好的控制精度,工作稳定可靠,可以满足农田插秧实际工作的要求,但需要进一步开展大量农田现场实验,在实际工况中对系统的实用性和稳定性进行分析,从而提升系统的工作性能。
In order to solve the problem of inconsistent depth of seedling transplanting caused by the transversal fluctuation of surface of paddy transplanting tray in farmland operation of high-speed rice transplanter, the research and development of seedling insertion depth adaptive adjustment system based on inclination detection of transplanting rice planting unit was carried out. Through the angle displacement sensor real-time detection of changes in the relative position of the two floating plates by the data acquisition and insertion depth control unit control stepper motor output, through the power transmission mechanism to change the lateral tilt angle of the entire tray, the tray and the floating plate Maintain a stable relative position, so as to achieve the purpose of stabilizing seedling depth. The static and dynamic experimental analysis on the rice transplanter simulation experiment platform shows that the system has good control precision, stable and reliable work, and can meet the actual requirements of farmland transplanting. However, a large number of farmland experiments need to be carried out. In actual conditions, The practicality and stability of the analysis, thereby enhancing the system’s performance.
