6农机使用与维修2023年第5期基于液压驱动器的精准施肥控制装置设计郑晓培，刘旦，孙磊，刘志鹏(长春工程学院工程训练中心，长春130012)摘要:为实现温室农业的精准施肥，设计了一种基于压电驱动器的施肥控制装置。该装置采用压电液压驱动和双肥料箱施肥，适用水肥一体化灌溉模式。确定了装置的工作条件、输出功率和载肥能力。当驱动介质气体含量极低时，工作条件为电压150V，频率350Hz，施加内压力0.04MPa。肥料重量1～1.5kg时，施肥装置的功率基本稳定，最高达92mW。与驱动介质气体含量较多时对比，装置的载肥能力提升3倍，功率提升1.517倍，具备更强的稳定性和工作效率。关键词:农业;精准施肥;水肥一体;液压控制中图分类号:S232.3文献标识码:Adoi:10．14031/j．cnki．njwx．2023．05．002ＲesearchonAccurateFertilizationControlDeviceBasedonHydraulicActuatorZHENGXiaopei，LIUDan，SUNLei，LIUZhipeng(ChangchunInstituteofTechnology，EngineeringTrainingCenter，Changchun130012，China)Abstract:Inordertoachieveaccuratefertilizationingreenhouseagriculture，afertilizercontroldevicebasedonpiezoe-lectricactuatorwasstudied．Thedeviceadoptspiezoelectrichydraulicdriveanddoublefertilizerboxesforfertilization，whichissuitablefortheintegratedirrigationmodeofwaterandfertilizer．Theworkingconditions，outputpowerandfer-tilizercarryingcapacityofthedeviceweredetermined．Whenthegascontentofthedrivingmediumisextremelylow，theworkingconditionsarevoltage150V，frequency350Hzandloadingpressure0.04MPa．Whentheweightoffertilizeris1kg－1.5kg，thepowerofthefertilizerapplicationdeviceisbasicallystable，andthemaximumpoweris92mW．Com-paredwithwhenthegascontentofthedrivingmediumwithalargeamount，thefertilizercarryingcapacityofthefertilizerapplicationdeviceisincreasedby3times，andthepowerisincreasedby1.517times，andthedevicehasstrongersta-bilityandworkingefficiency．Keywords:agriculture;accuratefertilization;integrationofwaterandfertilizer;hydrauliccontro基金项目:吉林省教育厅科学技术研究项目(JJKH20210680KJ);吉林省科技发展计划项目(20200402116NC);长春工程学院学校科技基金项目(320210005)作者简介:郑晓培(1986—)，女，河南漯河人，硕士，讲师，研究方向为农机化、压电...
