摘　　要：为保证丘陵地区秧苗实时移栽,提高移栽质量,阐述一种吊篮式自走移栽机行走装置和移栽机构的结构及工作原理。通过分析计算及1∶1的建模,验证行走装置的工作速度和结构布局形式,以及移栽机构各动作的协调性及栽苗质量。根据建模分析的结果,确定设计的主要参数,从而设计出行走机构装置主要部件轮架机构、主驱动变速箱机构、机架、升降机构、水平调节机构及控制装置等,移栽机构主要部件移栽变速箱机构、株距调节机构、曲柄连杆机构、鸭嘴移栽器、自动喂料机构等。通过样机试制和试验,结果表明:该机具可完成移栽株距(260~600 mm)、移栽深度(80~160 mm)可调的目标,工作效率高,同时具有结构合理紧凑、维护方便、操作简单等优点。To ensure real-time transplanting of seedlings in hilly areas and improve the quality of transplanting,this paper elaborates on the working principle and structure of a basket type self-propelled transplanting machine’s walking device and transplanting mechanism.Verify the working speed and structural layout of the walking device through analysis,calculation,and 1:1 modeling,and verify the coordination of various actions of the transplanting mechanism and the quality of the seedlings.Based on the results of modeling analysis,the main parameters of the design are determined,and the main components of the walking mechanism device—wheel frame mechanism,main drive gearbox mechanism,frame,lifting mechanism,horizontal adjustment mechanism and control device are designed.The main components of the transplanting mechanism—transplanting gearbox mechanism,plant spacing adjustment mechanism,crank connecting rod mechanism,duckbill transplanting device,automatic feeding mechanism,etc.are designed.Through prototype trial production and experiments,this machine can achieve the goals of adjustable transplanting spacing(260-600 mm),transplanting depth(80-160 mm),and high efficiency.At the same time,it has the advantages of reasonable and compact structure,convenient maintenance and simple operation.
