摘要
为降低深松作业的耕作阻力,对基于狗獾爪趾的仿生深松铲进行了振动减阻性能的研究,将仿生减阻技术与振动减阻技术相结合,研究减阻效果。同时,在耕作速度为0.6、1.0m/s和耕作深度为250、300mm的条件下进行仿生深松铲的振动减阻试验。试验结果表明:振动式深松铲的耕作阻力随着耕作深度和耕作速度的不断增大而增大;在相同的试验条件下,仿生深松铲振动耕作方式的耕作阻力比未带振动耕作方式的耕作阻力减小1 3.0 5%~1 8.9 4%,减阻效果明显。
To reduce tillage resistance,this paper research the vibration anti- drag of the bionic subsoiler based on the badger claws,and study the anti- drag effect that the bionic anti- drag technology combined with the vibration anti-drag technology. And the bionic subsoiler vibration anti- drag test condition was working as the speed of 0. 6m/s and 1.0m/s,the tillage depth of 250 mm and 300 mm. The result shows that the tillage resistance of the vibration subsoiler increased with the increasing of tillage depth and speed. The tillage resistance of the bionic subsoiler with the condition of vibration was reduced by 13. 05% ~ 18. 84% and the anti- drag effect was obvious in comparison to the bionic subsoiler with no vibration under the same test conditions.
