减粘降阻是改善开沟器工作性能的方法之一。根据表面改形和表面改性可减粘降阻的原理，设计出多种表面改形且表面改性的疙瘩开沟器。在含水量１２．９％～２８．１％范围内进行了试验。土壤含水量为１２．９％时，开沟器出现粘土现象；土壤含水量为２２％时，开沟器的粘土现象最严重，土壤含水量为２８．１％时，开沟器的粘土现象有所减弱。开沟器的牵引阻力随着土壤含水量的增加而增加，土壤含水量超过２２．０％时，开沟器牵引阻力有所下降。牵引阻力随开沟器牵引速度增加而增加，然后出现下降趋势。在牵引速度为７ｋｍ／ｈ时，牵引阻力最大。研究结果表明，Ａ０４２、Ａ１３２不锈钢焊条堆焊的疙瘩开沟器具有显著的减粘降阻效果。
One of the ways to improve the working performance of opener is to reduce the viscosity and reduce the resistance. According to the theory of surface modification and surface modification, it can reduce the viscosity and reduce the resistance, and design a variety of surface-modified and modified pimple openers. The moisture content of 12.9% to 28.1% range of experiments. When the soil water content was 12.9%, the opener appeared clay phenomenon. When the soil water content was 22%, the opener’s clay phenomenon was the most serious. When the soil water content was 28.1%, the opener’s clay phenomenon Weakened. The drag resistance of opener increases with the increase of soil water content. When the soil water content exceeds 22.0%, the drag resistance of opener decreases. Traction resistance increased with the opener speed, and then decreased. Traction at a maximum traction speed of 7km / h. The results show that A042, A132 stainless steel electrode surfacing pimple opener has a significant reduction in viscosity reduction effect.
