Abstract

To address the low mechanization level, poor adaptability, and insufficient sowing accuracy of potato planters in the hilly areas of Sichuan, a high-precision intelligent potato planter based on an electric chassis was developed. The integrated design ensures power matching between the electric chassis and the seeding system, while photoelectric and radar sensors enable real-time seed-metering monitoring and missing-seed compensation. A central composite design was used to optimize travel speed and seed-metering linear speed, with qualified spacing rate as the evaluation index. Results revealed a significant interaction between the two parameters. The optimal combination, determined via regression analysis, was 0.36 m/s (travel speed) and 0.23 m/s (seed-metering linear speed), yielding a qualified spacing rate of 98%. This study validates the feasibility and application potential of the electric chassis planter for hilly regions, offering a technical reference for the electrification and intelligent development of potato planting equipment.

本文针对四川丘陵山区马铃薯播种机械化程度低、现有播种机适应性差及播种精度不高等问题，研制了一款基于电动底盘的高精度智能化马铃薯播种机。通过一体化结构设计，实现了电动底盘与播种机的动力匹配,集成光电传感器与雷达传感器构建智能监控系统，实现了排种过程的实时监测与空穴补偿。采用中心复合设计试验，以行走速度和排种器线速度为因素优化作业参数，结果表明二者交互作用对合格率影响显著，最优参数组合为行走速度0.36 m/s、排种器线速度0.23 m/s，此时种薯间距合格率达98%。研究验证了电动底盘播种机在丘陵山区应用的可行性与优势，为马铃薯播种机的电动化、智能化发展提供了有效技术方案。
