摘　　要：为实现家禽养殖中的自动化精准饲喂,设计一种基于PLC的颗粒饲料自动投放装置。该装置以PLC为控制核心,以接近开关为位置检测元件,利用电磁铁驱动落料部件的动作,通过触摸屏设定落料时间,实现饲料的自动定量投放。饲料投放试验以原粮混合颗粒饲料为研究对象,试验结果表明:在落料口开口面积不变的情况下,落料平均重量与落料时间呈现出线性关系,为进一步研究家禽的自动变量饲喂装置提供理论基础。An automated feed dropping machine was designed in order to solve the problem of automated and precise feeding for fowl in factory breeding scale.In this machine,PLC（Programmable Logic Controller）was taken as the control core of the system,electromagnet was adopted to control the movement of executive mechanism,proximity switch was used as position detecting component,and touch screen was employed for setting the parameters of dropping time.Pellet feed which was a mixture of grains was tested in experiment.The results showed that feed＇s average weight and dropping time had linear relationship and had provided design parameters and theory for further research of automated variable feeding machine.
