摘要
针对现有免耕播种机结构复杂、动土量大、所需拖拉机功率大、防堵效果不明显等缺点,设计了直插式精量点播器,依据仿生学原理确定该点播器采用偏置曲柄滑块机构,并基于复数矢量法对其进行了运动学分析,得到该偏置曲柄滑块机构的运动学方程,通过ADAMS软件进行运动学仿真,得出结论:播种深度为85mm,播种角度为93°,纵向土壤扰动量为8%,符合免耕播种技术要求的同时,有效的解决了现有免耕播种机存在的技术难题,最后进行实验,验证了结论的可靠性。
In view of that the existing no-tillage planter has many problems that are complex, ground-breaking large, required tractor power, preventing clogging effect is not obvious, an in-line precision dibbler was designed, determined in accordance with the principle of bionics using the on-demand offset crank slider mechanism, and based on the complex vector method of kinematics analysis of the eccentric crank, getting the kinematics equations of slide mechanism Kinematics simulation by ADAMS software, draw the conclusion： the sowing depth was 85mm, sowing angle of 93°, the vertical soil disturbance quantity was 8%, to meet the requirements of no tillage technology at the same time, effectively solving the technical problems existing in no tillage planter, and finally it carries on the experiment, verifying the reliability of the conclusion.
