摘　　要：基于磁吸式播种机的原理,设计出了一种新型的磁吸板式穴盘精密播种机。该播种机采用错板式结构,吸种时钉板上的铁钉被磁板内的磁条磁化,铁钉吸取磁粉包衣种子完成吸种过程;当磁板和钉板产生错位时,铁钉上的磁力消失,种子在重力作用下落入导种板中,完成排种过程。试验结果表明,磁条磁场强度为180 m T,磁铁与铁钉之间的距离为0.3 mm,种子磁粉含量为5%,钉长为20 mm,钉子直径为1.8 mm时,该播种机单吸率达到了89.8%。In this paper,based on the magnetic principle,a new type of plate type plug seeder was designed based on magnetic attraction. Using the misplaced plate structure of the seeding machine,in the suction,the nails on the nail plate is the magnetization of the magnetic strip inside the magnetic plate,with nails absorbing magnetic powder coating seed absorption process; When the magnetic plate and the nail plate produce dislocation,nails on the magnetic force will disappear,seed falls to the guide of plate under gravity,completing the process of planting. The experimental results showed that the magnetic field strength is 180 m T,the distance between the magnets and iron nails is 0. 3 mm,seed powder content is 5%,nail is 20 mm long,nail diameter is 1. 8 mm,and the machine has the highest rate of single suction,which means the rate of single seed is the best,reaching 89. 8%.
