摘  要:
【目的】针对有机肥播撒问题,研究设计了一种离心式变量撒肥机,阐述了该机的结构及工作原理.【方法】对影响撒肥效果的各因素进行了正交试验研究.【结果】当机具前进速度为5.5km/h,链板转速为5r/s,撒肥圆盘转速为540r/min时,得到均匀性变异系数为10.2%,作业幅宽为19.3m,施肥量为1 268.97kg/667m2.【结论】前进速度、圆盘转速及链板转速对有机肥抛撒的均匀性变异系数、幅宽和撒肥量均有影响,撒肥圆盘的转速对作业质量影响极显著,其次为链板转速,最后为机组前进速度.

摘  要:
【Objective】To develop a kind of the centrifugal variable rate fertilizer for fertilizing organic fertilizer in farmland,and descript the structural characteristics and working principle of the machine.【Method】The effect factors were screened by orthogonal test.【Result】When the forward speed was 5.5km/h,the rotation rate of disk was 5r/s,and the rotation rate of harrow-chain was 540r/min,the coefficient of variation was 10.2%,the bed width was 19.3 m,and the fertilizing amount was 1 268.97kg/667m2.【Conclusion】Coefficient of variation,bed width and fertilizing amount were influenced by forward speed,rotation rate of disk and rotation rate of harrow-chain.The fertilization effect was significantly affected by speed of fertilizing disk,then was rotation rate of harrow-chain,the forward speed of fertilizer had a less effect.
