针对现有深松铲存在的耕作阻力较大及能耗较高等问题,利用仿生学原理将狗獾爪趾的曲线应用到深松铲的结构设计中,设计了一种铲柄刃口为多项式曲线、铲尖为圆弧形的新型深松铲。为研究其耕作效果,将所设计的深松铲与国标深松铲进行了室内土槽对比试验。试验结果表明:在相同的深松试验条件下,仿生深松铲比国标深松铲的耕作阻力减小了13.33%~21.72%,仿生深松铲减阻效果明显;仿生铲柄与国标铲尖组合比国标深松铲耕作阻力减小了3.01%~7.61%,仿生铲尖与国标铲柄的组合比国标深松铲耕作阻力减小了7.67%~16.97%,仿生铲尖的减阻效果显著于仿生铲柄的减阻效果。
針對現有深鬆鏟存在的耕作阻力較大及能耗較高等問題,利用倣生學原理將狗獾爪趾的麯線應用到深鬆鏟的結構設計中,設計瞭一種鏟柄刃口為多項式麯線、鏟尖為圓弧形的新型深鬆鏟。為研究其耕作效果,將所設計的深鬆鏟與國標深鬆鏟進行瞭室內土槽對比試驗。試驗結果錶明:在相同的深鬆試驗條件下,倣生深鬆鏟比國標深鬆鏟的耕作阻力減小瞭13.33%~21.72%,倣生深鬆鏟減阻效果明顯;倣生鏟柄與國標鏟尖組閤比國標深鬆鏟耕作阻力減小瞭3.01%~7.61%,倣生鏟尖與國標鏟柄的組閤比國標深鬆鏟耕作阻力減小瞭7.67%~16.97%,倣生鏟尖的減阻效果顯著于倣生鏟柄的減阻效果。

The problem of greater cultivation resistance , higher energy consumption and other issue exists in the tradi-tional subsoiler .In this paper , the curve of the badge claws is applied in the structural design of subsoiler according to the principle of bionics , it has designed a new subsoiler which contains the share shaft of polynomial curve and the sweep point of circular arc .In order to study the cultivation effect , we do the contrast experiment to bionic subsoiler and tra-ditional subsoiler in soil-bin laboratory.The result showed that the bionic subsoiler's tillage resistance decreased by 13 .33% ~21 .72%and the drag reduction effect was obvious in comparison to traditional subsoiler under the same test conditions .If the bionic share shaft combined with the traditional sweep point , the tillage resistance will be reduced by 3 .01%~7 .61% compared to the traditional subsoiler .While the combination of the bionic sweep point and the tra-ditional share shaft decreased by 7 .67%~16 .97% than the traditional subsoiler in the tillage resistance.Thus the difference of the drag reduction effect of the bionic sweep point and the bionic share shaft was significant .
