摘　　要：针对保育猪死淘率高、饲料浪费多、人员劳动强度大等问题,搭建粥料机样机测试平台,并设计保育猪智能粥料饲喂系统,系统由机械本体、手持终端、中央控制器和云平台四部分组成。对机械本体中螺旋输送机安装高度、排料通道内径和破拱结构形式进行正交试验,得到参数最优组合为:螺旋输送机安装高度为60 mm,排料通道内径42 mm,破拱结构采用上下破拱结构结合的形式,此组合下填充效率最优,λ值为14.2 g/r。系统供水量误差为1.43%;当水料比≥1.5∶1时,食槽液位监测装置满足系统工作要求,研究可为保育猪智能粥料饲喂设备的研发提供参考。Aiming to solve the problems of high mortality rate of nursery pigs,high feed waste,and high labor intensity,a prototype testing platform for a porridge machine was built,and an intelligent porridge feeding system for nursery pigs was designed.The system was composed of four parts:a mechanical body,a hand-held terminal,a central controller,and a cloud platform.Orthogonal experiment was carried out on the installation height of screw conveyor,the inner diameter of discharge channel and the structure of broken arch in the mechanical body.The optimal parameters combination is obtained as follows:screw conveyor installation height was 60 mm,discharging channel diameter was 42 mm,the broken arch structure adapted the combination form of upper and lower broken arch structure,the filling efficiency was optimal,the value ofλwas 14.2 g/r,and the water supply error of the system was 1.43%.When the ratio of water to feed was equal and greater than 1.5∶1,the liquid level monitoring device can satisfy the requirements of the system.The research can provide a reference for the research and development of feeding equipment for piglets.
