Abstract

Soil adhesion markedly increases operational resistance, diminishes efficiency, and elevates energy consumption in the soil contact components of agricultural machinery. This study introduces a method for reducing adhesion and facilitating detachment through electroosmosis, while also examining its effects on energy consumption via pull-out and slip tests. The results indicate that electroosmosis generates a water film at the metal interface, which significantly decreases the interfacial adhesion force. At 60V and a soil moisture content of 30%, the pull-out force is reduced by 21.48N, and the slip angle decreases by 55.8°. Compared to traditional methods, electroosmosis not only lowers energy consumption but also effectively mitigates wear and maintenance costs.

土壤与农机触土部件间的粘附作用会显著增大作业阻力、降低工作效率、增加能源消耗，进而影响作业质量。本文通过拉拔、滑移试验分析不同金属材料与不同含水率土壤接触时的电渗效应以及能量消耗分析提出了一种基于电渗技术的减粘脱附方法。结果表明：电渗作用能引导土壤水分向阴极迁移，在金属界面形成润滑水膜，从而显著降低界面粘附力；在电压60V、土壤含水率30%的条件下，铜界面的拉拔力降低21.48N，滑移角下降55.8°。与传统减粘方法相比，电渗技术能耗更低，并能有效减少农机设备的磨损与维护成本，为触土部件的设计与性能优化提供了新的技术途径。
