摘要
本文的毕业设计主要是围绕香蕉苗移栽机展开,着重于整机的总体设计方案以及传动装置的设计计算。总体设计方案是移栽机通过与东方红X900型号拖拉机三点悬挂牵引,利用打孔装置开坑,同时地轮随主机前进而转动,通过链轮驱动中间轴旋转;中间轴上安装有链轮,通过链传动驱动播种装置和进行移栽,使种块孔底;最后利用覆土器进行覆土作业,完成整个双垄作业过程。传动装置主要是关于两条传动链同步工作达到有效的移栽作业,采用链传动进行动力传递,结构紧张,传递效率较高。整机采用平面四杆式移栽,双曲柄连杆打孔机构与下种装置联动的结构;移栽秧苗操作人员劳动强度减小、减少移栽时间、不损伤幼苗;该机具结构紧凑且新颖,降低了生产成本。

Abstract
     The graduation design of this paper is mainly around the banana seedlings transplanting machine to start, focusing on the overall design of the machine and the transmission design and calculation. The overall design is the transplant machine with the Dongfanghong X900 model tractor three-point traction, the use of drilling device open pit, while the wheel with the host forward and rotation, through the sprocket to drive the middle shaft rotation; , Through the chain drive to drive the sowing device and transplanting, so that the end of the block hole; Finally, the use of casing to cover operations, complete the entire ridge operation process. Transmission is mainly about the two drive chain synchronization work to achieve effective transplanting operations, the use of chain drive for power transmission, structural tension, transmission efficiency is higher. The whole machine adopts the structure of plane four-pole transplanting and double-crank connecting rod drilling mechanism. The transplanting seedling operator has reduced the labor intensity, reduces the transplanting time and does not damage the seedlings. The machine pact and novel , Reducing the cost of production.
Key words: banana seedlings; transplanting machine; design scheme; transmission device
