| 摘 要： | 为检测旋耕-碎茬仿生刀片的田间作业功耗和作业质量,利用应变片型扭矩传感器对安装仿生刀片的两行耕整机进行田间作业功耗电测试验,依照国标测试方法测定作业质量,并与国标旋耕刀和常用碎茬刀进行了对比。田间试验结果表明:旋耕试验中,旋耕-碎茬仿生刀片的单位切土面积功耗小于国标旋耕刀,且作业质量优于国标旋耕刀;碎茬试验中,仿生刀片单位切土面积功耗小于常用碎茬刀,作业质量较碎茬刀稍差,但依旧满足国标要求。该研究工作为实现只应用一种刀片来完成旋耕和碎茬2种不同作业的目标提供了参考。

| Abstract: | In order to examine the power consumption and working quality, the bionic blades for soil-rototilling and stubble-breaking (bionic blade for short), national standard rototilling blades and common stubble-breaking blades were mounted respectively on rototilling-stubble-breaking machine to perform soil-rototilling and stubble-breaking tests. The power consumption of the three kinds of blades were tested by electric measurement method respectively, and the working qualities were tested in accordance with national standards. Because of the difference of blades' soil-cutting range, the power consumption of unit area of soil-cutting was taken as test index. The results showed that the power consumption of unit area of soil-cutting of bionic blade was less than that of national standard rototilling blade, and the working quality of bionic blade was better than that of the national standard rototilling blade. The power consumption of unit area of soil-cutting of biomimetic blade were less than that of common stubble-breaking blade, and the working quality of stubble-breaking of biomimetic blade was little worse than that of the common stubble-breaking blade, but it met the requirement of national standard of China. The research provided a reference to achieve soil-rototilling and stubble-breaking by using one kind of blade. |
