摘要
[目的]研发作业可靠且适应新疆玉米种植模式的免耕播种机具.[方法]采用运动分析及结构设计方法,设计免耕播种机清茬机构、排种器及滴灌带铺设机构,并进行田间试验验证.[结果]机具前进速度在5 km/h时通过性良好,秸秆清理率达到79.44%,满足免耕播种作业要求;播种合格指数为 91.33%,漏播指数为3.18%,重播指数为5.49%,播种均匀性满足行业标准.[结论]滴灌区玉米精量免耕播种机满足设计要求,可以有效清茬、播种及铺设滴灌带.
Abstract
[Objective]In the hope of developing no-till seeding machines with reliable operation and a-daptable to the cropping pattern in Xinjiang.[Methods]The no-till planter stubble clearing mechanism,seed rower and drip irrigation belt laying mechanism were designed by means of motion analysis and structural design,and field verification tests were conducted.[Results]The machine had good trafficability characteris-tic at the forward velocity of 5 km/h,and the stubble clearing rate reached79.44%,meeting the requirements of no-till seeding operation;The seeding pass index was 91.33%,the missed seeding index was 3.18%,the reseeding index was 5.49%,and the seeding uniformity met the industry standard.[Conclusion]The corn precision no-till planter in drip irrigation area meets the design requirements and can effectively carry out stubble clearing,seeding and drip irrigation belt laying operations.
