摘要
针对秸秆还田存在耕深不足的问题,设计一种大耕深且稳定性高的旋耕机。通过分析旋耕刀运动时受到的土壤阻力和旋耕刀端点运动轨迹,采用双轴Z形阶梯状空间结构和双轴分层旋耕切土工艺,得到旋耕刀轴空间布局和旋耕刀排列,设计出双轴旋耕施肥播种复试作业机。通过田间试验验证,该机具能实现平均耕深大于22 cm的工作要求,耕深稳定性约为93%,实现了深耕碎土和施肥播种一次性作业,大大节省了耕作能耗和成本,可为今后双轴旋耕机的设计与研究提供参考。
A double-axis rotary tillage compound machine is designed to solve the problem of insufficient tillage depth in straw returning.Through the analysis on soil resistance during rotary blade movement and the trajectory of rotary tiller,double-axis Z-shaped ladder space structure and double-axis layered rotary tillage soil cutting technology are adopted to abtain the spatial layout of rotary cutter shaft and arrangement of rotary blades.Thus the double-axis rotary tillage compound machine with fertilization and sowing functions being designed.The field experiments verify that the machine meets the working requirements of average tillage depth greater than 22 cm with tillage depth stability as about 93%,and realizes one-time operation of deep tillage and fertilization and sowing significantly saving energy and cost of farming,which has certain reference significance for the design and research of double-axis rotary tiller in the future.
