仿生减阻深松铲设计与试验

将小家鼠爪趾高效的土壤挖掘性能应用于深松铲减阻结构设计中,设计了铲柄破土刃口为指数函数曲线型减阻深松铲。为了对比耕作阻力,应用仿生减阻深松铲与传统深松铲进行了田间深松耕作试验。结果表明,耕深和前进速度对耕作阻力均有显著影响,且耕作阻力随着耕深和前进速度的增大而增大。在相同试验条件下,仿生减阻深松铲与传统深松铲相比,耕作阻力降低8.5%~39.5%,减阻效果明显。

Design and Experiment of Bionic Anti-drag Subsoiler

Efficient soil digging property of claw toe of Mus musculus was applied to the structure design of anti-drag subsoiler. The anti drag subsoiler had exponential curve shape of soil-cutting edge of shaft. To compare tillage resistance, the subsoiling experiments were conducted using bionic anti-drag subsoiler and traditional subsoiler. The results showed that both tillage depth and forward velocity could affect on subsoiling resistance significantly and the tillage resistance increased with the tillage depth and forward velocity. The tillage resistances of bionic anti-drag subsoiler were reduced by 8.5% to 39.5% respectively compared with traditional subsoiler under the same experimental conditions and the effect of reducing resistance was obvious.
