垂直耕作下的圆盘开沟器作业性能测试与分析
Performance testing and analysis of different disc openers for vertical tillage
摘要
Abstract
Vertical tillage is an advanced method of conservation tillage,but there is a lack of research,testing,and analysis in China on the performances of vertical tillage tools.There is especially a lack of detailed experimental data for evaluating the performance of vertical tillage tools in the rice-wheat rotation areas.Therefore,field experiments were conducted on three typical vertical tillage tools(flat disc opener,rippled disc opener,and notched disc opener)in rice stubble fields using an in-situ tillage experimental platform.The tillage resistance,straw cutting efficiency,soil disturbance width,and soil cutting depth of the three disc openers were tested and analyzed at different tillage depths(70mm,100mm,130mm).The results indicated that the geometric shape of tillage tools and tillage depth have a significant impact on tillage performance.Among the three types of disc openers,the notch disc has lower draught resistance and vertical resistance,and the straw cutting efficiency is the highest;The tillage resistance of the rippled disc is slightly higher,but its soil disturbance width is the largest,and the straw cutting efficiency is closer to that of the notched disc.The tillage resistance,straw cutting efficiency,and soil cutting depth of the three types of disc openers all increase with the increase of tillage depth.When the tillage depth increases from 70mm to 130mm,the draught resistance,vertical resistance,straw cutting efficiency,and soil cutting depth of the corrugated disc increase by 294N,385N,11.2%,and 54.9 mm,respectively.Therefore,it is necessary to select appropriate tillage tools and working parameters according to specific job requirements for vertical tillage.关键词
