| 摘要: |
| 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。 |

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