Introduction Cornisanimportantfoodcropcultivatedworldwide.Cornplantingisoneofthemostimportantlinksinagriculturalproduction.Accordingtostatistics,theyieldperunitareaofcorniscloselyrelatedtotheplantingdensityandtheuniformityoftheplantspacing.Traditionalmanualplantingcannotmeettherequirementsofhighyieldandprecisionplanting.Therefore,thedesignandresearchofacornprecisionplantingdevicewithhighefficiencyandaccuracyareurgentlyneededtoimprovetheyieldandqualityofcorn. Theprecisionplantingdeviceisadeviceusedtocontroltheseeddepth,spacing,andplantingdensitytomeettheneedsofhigh-yieldandhigh-qualitycornproduction.Atpresent,thepreciseplantingdevicesonthemarketaregenerallybasedonmechanicalstructures,suchascirculardrillsandplanterplates.However,thesemechanicalstructureshavelimitationsintheirapplication.Themainproblemsincludelowplantingaccuracy,highenergyconsumption,andpooradaptabilitytodifferentseedvarieties.Inrecentyears,duetotheadvantagesofhighprecision,lowenergyconsumptionandgoodadaptability,thepneumaticprecisionplantingdevicehasattractedgreatattention.
