三七精密排种器的参数优化设计

Parameter Optimization Design of Sanchi Precision Seed Metering Device

工厂化育苗是三七产业化发展的必然选择,精密播种机是实现工厂化育苗的关键设备。为此,针对目前已设计研发的窝眼轮式三七精密排种器进行工作性能及结构特点分析,通过相关参数之间关系的计算并利用Mat Lab对多组数据进行数值分析,最终得到几组排种管高度H、播种机前进速度υ与电机转速ω之间的理想组合;并与实验数据进行对比,得到一组最优数据。参数优化设计是一种行之有效的方法,通过优化后的参数能更加适合实际生产的需求,从而在节约成本的前提下提高生产效率和增加产量。

Factory nursery is the inevitable choice for notoginseng industrialization development.Precision planter is nec-essary equipment for factory nursery.A cell wheel Sanchi precision seed metering device.The performance and structural features of the existing cell wheel seed metering device were analyzed in this paper.Then by deducing the relational ex-pression between related parameters and numerical analysis of multiple sets of data using Matlab, several sets of ideal combination of data between the seed tube height H, the forward velocity of the machine V and motor speed were ob-tained;Compared with the experimental data,a set of optimal data war found.Parameter optimization design is an effective method,the optimized parameters can be more suitable for the actual production needs so as to improve the production ef-ficiency and increase output in terms of cost saving under.
