玉米秧苗移栽机的设计

摘要

Based on the advantages and disadvantages of the existing models , a new kind of corn seedling transplanter is designed.It can ditch,plant seedling,cover the soil,suppress the soil.It are made of planting seedling mechanism ,con-veying mechanism ,furrow opener ,press wheel ,overbite soil mechanism ,transmission mechanism ,suspension part ,supple-mentary part and so on .Planting seedling mechanism , transmission mechanism , conveying mechanism , frame and wheel carrier are introduced in detail .Plant seedling mechanism is evolved from crank and rocker mechanism , connecting rod is regarded as planting arm;gear transmission and chain transmission are applied into the transmission mechanism ; drum and belt are applied into the conveying mechanism .The practical production proves that the efficiency of the machine is 85%,planting speed is high .It reduces the fatigue strength of planting hand and it is convenient for farmer .%在总结现有机型优缺点的基础上，设计了一种新型玉米秧苗移栽机，能够一次性完成开沟、栽苗、覆土及镇压等工序。该机器由栽植机构、输送机构、开沟器、镇压轮、覆土机构、传动机构、悬挂部分及辅助部分等组成。为此，重点介绍了栽植机构、传动机构、输送机构以及机架及轮架的设计。栽植机构由曲柄摇杆机构演化而来，连杆作为栽植臂；传动机构采用齿轮及链轮传动；输送机构采用滚筒和皮带。实验证明：该机栽植效率在85％以上，性能稳定，栽植速度较高，减少了栽植手的疲劳强度，给农民带来较大的方便。
