摘要
为探明叶片倾角、叶片数、行进速度在不同水平下对离心圆盘式三七施肥机在斜坡上的施肥均匀性的影响,给离心圆盘式三七施肥机的设计及优化提供理论依据。采用标准筛筛分法、斜坡法、细沙填充法等方法测定肥料颗粒的物理参数;选取叶片倾角、叶片数、行进速度为因素,肥料颗粒的分布变异系数为试验指标,利用EDEM软件对施肥过程进行正交仿真试验。结果表明,叶片倾角为-20°、叶片数为4片、施肥机行进速度为0.6m/s时,肥料颗粒分布变异系数最小,为16.73%。经过分析,对肥料颗粒分布变异系数的影响为叶片倾角>叶片数>行走速度、叶片倾角和叶片数为显著性因素,行进速度为不显著因素。
The purpose of this paper was to find out the influence of blade inclination,number of blades and travel speed on the fertilization uniformity of centrifugal disc Panax notoginseng fertilizer machine on the slope at different levels,so as to provide a theoretical basis for the design and optimization of centrifugal disc Panax notoginseng fertilizer machine.The physical parameters of fertilizer particles were determined by standard screening method,slope method,fine sand filling method and other methods;the leaf inclination angle,number of blades,and travel speed were selected as factors,the coefficient of variation of fertilizer particles was used as the test index,and the orthogonal simulation test of the fertilization process was carried out by EDEM software.The results showed that when the blade inclination angle was-20°,the number of blades was 4,and the travel speed of the fertilizer applicator was 0.6m/s,the smallest coefficient of variation of fertilizer particles was 16.73%.After analysis,the influence on the coefficient of variation of fertilizer particles was as follows:blades inclination>number of blades>travel speed,blades inclination and number of blades were significant factors,and travel speed was not significant factor.
