针对现有移栽机移栽效率低及膜上作业存在刮膜、撕膜等问题,研究设计了一种由双曲柄摇架连杆构成的蔬菜快速移栽装置. 该装置通过曲柄的旋转和摇架摇摆,使打穴体钝角入土、锐角出土,以及打穴体实现相对后移;增速装置增加打穴体入土速度,缩短打穴时间,实现了打穴体零位移条件下的快速移栽作业. 仿真实验表明:该装置可以实现在2 km/h行进速度下打穴体的"Y"运动轨迹,满足蔬菜移栽的农艺要求,且保证移栽性能、克服刮膜现象、提高作业速度.
針對現有移栽機移栽效率低及膜上作業存在颳膜、撕膜等問題,研究設計瞭一種由雙麯柄搖架連桿構成的蔬菜快速移栽裝置. 該裝置通過麯柄的鏇轉和搖架搖襬,使打穴體鈍角入土、銳角齣土,以及打穴體實現相對後移;增速裝置增加打穴體入土速度,縮短打穴時間,實現瞭打穴體零位移條件下的快速移栽作業. 倣真實驗錶明:該裝置可以實現在2 km/h行進速度下打穴體的"Y"運動軌跡,滿足蔬菜移栽的農藝要求,且保證移栽性能、剋服颳膜現象、提高作業速度.

In order to solve the problem of existing transplanting machine transplanting efficiency is not high and mem -brane operation is blown film, tear film and other issues.This study designs a composed of double crank cradle connect-ing rod vegetable transplanting device, through which the rotation of the crank and cradle swing to make the construction body obtuse angle into the soil and acute angle unearthed, so the construction body achieve relatively backward;Construc-tion growth device is designed to increase the speed of the grave and shorten the construction time, realizing the zero dis-placement under the condition of the construction body transplanting work quickly.Simulation experiments show that the device can be realized under the 2 km/h speed of construction of"Y" trajectory, and meet the agronomic requirements of vegetable transplanting, ensure transplanting performance, overcome the phenomenon of blown film and can improve the operation speed.
