犁刀 meaning in English
[农业] coulter; skim cutter
◇犁刀柄 coulter shank; 犁刀头 coulter
Examples
- Ustable cone colter bearing
圆犁刀的可调式锥形轴承 - Concave disk colter
凹面圆犁刀 - But there are no report of the design and research on bionic adhesion decreasing efficiency of the standard disk plow that has a great difference to other soil touched component on working manner and force support status currently . in this paper , standard disk plow was selected to be research object . with disk plow referred as bionic components and the theory of soil touched component adhesion decreasing and resistance reducing applied , we modified its shape and promoted its property
本文选择标准型圆盘犁作为试验研究对象，以圆盘犁刀为具体的仿生设计部件，运用触土部件减粘脱土理论，在仿生表面改性、改形研究以及传统圆盘犁刀结构基础上，首先对圆盘犁刀进行了若干种仿生非光滑结构不同组合设计，继而制作了两组试验用仿生圆盘犁刀，最后对设计加工的仿生圆盘犁刀，分别进行了正交试验设计和二次回归试验设计，在室内土槽中进行了研究条件下的耕作试验。 - The result of orthogonal experiment and secondary regression experiment on the bionic disk plows indicates that the bionic non - smooth partial sphere structure cell can decrease resistance by almost 30 % than common plow in the condition that the structure and distribution combine rationally . therefore , the bionic design and experiment research on disk plows is very significant
仿生圆盘犁刀的正交试验和二次回归试验结果分析表明，如果圆盘犁刀的仿生非光滑球冠结构单元的结构参数和分布组合搭配合理，仿生圆盘犁比普通圆盘犁可减少阻力约30 ，因而本文对圆盘犁刀进行仿生设计与试验研究是非常有意义的。
