悬挂式施肥播种机阻漏肥装置的研究

The Principle and Design of the Fertilizer Leak-preventing Device for Mounted Fertilizer Seeders

针对使用搅刀－拨轮式排肥器的悬挂施肥播种机在施尿素等颗粒状肥料时，非工作状态所发生的肥料严重漏失问题，研究设计了阻止漏肥装置。试验结果表明，该装置利用播种机被提升和落下动作即能自动控制挡肥活门启闭，不增加拖拉机驾驶员的操作负担，能有效解决上述排肥器的漏肥问题。

A fertilizer leak-preventing device is developed to stop fertilizer leakageon the stirring-knife-reel adjusting fertilizer distributor,especially severe when operatedwith granulated fertilizers such as urea during the non-working state of the distributor.The preventing valve is controlled automatically through the mounting and falling ac-tions of the distributor,thus needing no more help from the driver. This fertilizer leak-preventing unit can solve the problem of fertilizer lcakage of the fertilizer distributor.
