旋耕铊刀前端弯曲部分的工作面其重要性相当于犁的犁体曲面,它决定机具的耕作性能。作者提出了旋耕铊刀在耕作阻力最小、且具有良好碎土和翻转抛土性能时,前端弯曲部分工作面的设计理论,并以一般圆弧表示工作面断面形状的方法,导出了求解工作断面形状的简便方法。采用本设计方法,可根据设计条件,比较容易求出理论上更为合理的工作断面形状。
The importance of the working face of the curving part of the tip of the rotary tillage tool is equivalent to that of the plow body, which determines the tilling performance of the implement. The authors put forward the design theory of the front curved part working face when the rotary tillage tool has the lowest tilling resistance, the fine groundwork and the overturning and soil-throwing performance, and the general circular arc shows the cross-sectional shape of the working face. Simple and convenient method of section shape. Using this design method, according to the design conditions, it is relatively easy to find a more reasonable theoretically the shape of the working cross-section.
