机引犁壁及其脱土性

Plough Moldboard and Its Soil Scouring Property

土壤粘附是犁耕作业时犁壁经常遇到的问题,本文分析了我国机引犁壁材料的历史沿革、目前状况及其脱土特性,提出了通过改变合金成分、金相组织及表面状态来改善犁壁脱土性是可行途径。

Soil adhesion is a problem which is often faced when plough moldboard works. This paper deals with the history evolution and present situation of the tractor drawing plough moldboard in China. It concludes that it is possible to change alloy content , microstructure and surface condition for improving the property of soil scouring.
