为满足作物生长期对肥料的不同需求,人们正研究通过控制肥料颗粒内部养分释放速率的缓控释肥,试验表明其可减少施肥量,避免资源浪费和环境污染。目前,袋装缓控释肥的施放主要采用手工,耗工费时,效率低下。为实现袋装缓控释肥机械化施放,该文根据其基本物理参数及力学特性,对袋装肥有序排队机理、余量清理、定量施放进行研究,设计了一种袋装缓控释肥的有序排肥装置,它由偏心分离机构、清理机构、排肥机构及动力传输机构组成,以偏心轮转速、毛刷轮转速及毛刷轮与刮板输送带之间的间距为影响因素,以合格指数、漏排指数、重排指数为评价指标,进行正交试验,得出各因素对评价指标的影响关系。利用Desi...

By controlling the release rate of fertilizer nutrients, bagged slow-release fertilizer can reduce the amount of fertilizer application. In the past, the fertilization method of bagged slow-release controlled release fertilizer was mainly manual, high cost and low efficiency. In order to realize the mechanized application of bagged slow-release fertilizer, we measured its basic physical parameters and mechanical properties, based on the measured data, we had studied the ordered queuing mechanism, residual material cleaning and quantitative appl...
