摘要
为探讨肥料抛撒机的撒肥性能,从理论上分析了颗粒肥料在撒肥盘和脱离撒肥盘后的运动机理和颗粒肥料脱离撒肥盘的条件,并通过分析颗粒肥料在撒肥盘和脱离撒肥盘后运动过程中的受力情况,建立了相应的运动方程,进一步得到了颗粒肥料离开撒肥盘时速度的函数关系以及颗粒抛撒幅宽的函数关系,可为肥料抛撒机设计优化和研究提供较好的参考。
Spreader mechanism is a key component of fertilizer spreader,which performance direct affect the quality of spreading.A theoretical analysis was conducted the motion state of granular fertilizer during moving in spinner disc and leaving.Analysis of condition that granular fertilizer can leave spinner disc,an analytical calculation the state of granular fertilizer subjected to force under inertia effect during fertilizer was moved to disc border,and a motional equation was established.And the function relations were found velocity of granular fertilizer leaving spinner disc and fertilizer spreading breadth.
