使用平面铰链四杆机构来驱动鸭嘴实现栽植器的功能,以满足特定秧苗移栽的农艺需求。文中使用优化技术来设计满足要求的四杆机构,采用可变目标点,分两个层次来优化,使用改进的多种群遗传算法进行优化。描述了尺寸设计的整个过程,得到了车身前进的速度波动对零速投苗性能影响较小的结论,并进行了一个算例的计算。当移栽不同的作物时,根据该作物的农艺要求,使用文中设计方法,可以快速设计出能满足移栽要求的四杆机构。
The use of a flat-hinged four-bar mechanism to drive duckbill implements the function of a planter to meet the agronomic needs of a particular seedling transplanting. In this paper, the optimization technique is used to design a four-bar mechanism to meet the requirements. The system uses variable target points and is optimized in two levels. The improved multi-population genetic algorithm is used to optimize the four-bar mechanism. The whole process of the dimension design is described. The conclusion that the speed fluctuation of the car body advance has little effect on the performance of the zero-speed seedling selection is obtained, and a calculation example is given. When transplanting different crops, according to the agronomic requirements of the crop, using the design method in the article, a four-bar mechanism capable of meeting the requirements of transplanting can be quickly designed.
