针对黑水虻虫沙机械化集料程度低的问题,结合黑水虻养殖特点与虫沙特性,设计一种螺旋式双向集料装置。阐述了该装置的结构组成与工作原理,对其关键部件双向螺旋进行了分析与参数设计。采用离散元软件建立了虫沙-双向螺旋装置的耦合仿真模型,模拟仿真了虫沙的集料输送过程,以螺距、螺旋轴径、螺旋转速、移动速度为试验因素,以质量流率为评价指标进行了四元二次回归通用旋转组合仿真试验。试验结果表明,各因素对质量流率影响主次顺序为螺旋转速>螺旋移动速度>螺旋轴径>螺距。以提高质量流率为目标,运用Design- Expert8.0.6软件进行参数优化,确定了最优组合:螺距153 mm、螺旋轴径29 mm、螺旋转速83...

To solve the low level of mechanization and high labor intensity in aggregating hermetia illucens sand,a bidirectional aggregating device of spiral type was put forward based on the breeding characteristics of hermetia illucens and the biological nature of hermetia illucens sand.The structure and working principle of the spiral bidirectional aggregating device were introduced.The key parts of the device were analyzed and the parameters were designed.The discrete element software was used to establish the coupling simulation model of inset-sand ...
