摘  要：
针对现有马铃薯播种机存在的株距、间隙不可调及振动效果不够理想等问题,对2CMX-4B型播种机的播种单元进行了改进设计。采用更换链轮的方式设计的株距调整装置,可根据不同地块和不同马铃薯品种的要求方便地调整播种株距;采取增设梯形凸起和调整手柄等措施设计的振幅调整装置,不仅能够振落薯种碗内多余的马铃薯种,而且振幅可调;采用增设导薯筒和调整螺杆的方式设计的间隙调整装置,能够方便地调整导薯筒与薯种碗之间的间隙,彻底解决了重播、漏播等问题。试验结果表明:改进后的播种机各项指标均符合国家标准要求,不仅提高了作业质量,而且增强了马铃薯播种机对不同地区、不同马铃薯品种的适应能力。

摘  要：
With the aim to solve the problems of plant spacing,gap and vibration amplitude of the seeding which could not be adjusted,and the unsatisfactory effect of vibration,the seeding-unit of 2CMX-4B-type seeder was redesigned.The spacing adjustment device could adjust the spacing by the way of replacing the sprockets,it could adjust the planting spacing easily depending on the require of different land and different potato varieties; the amplitude adjustment device contained the trapezoidal bump and adjustment handle,it could shake off the extra potatoes which were in potato tuber bowl and the amplitude could be adjusted; the gap adjusting device could adjust the gap by the potato guide tube and adjustment screw,it could regulate the relative position between the potato guide tube and the potato tuber bowl easily,and the problem of leakage or double seeding could be solved completely.The results showed that the indicators of the redesigned potato planter were in line with national standards.What is more,it could improve the quality of work and enhanced the adaptability of potato planter for different regions and different potato varieties.
