研制了一种新型蔬菜移栽机取苗装置。拾取装置从200个单元的托盘中提取幼苗，并将其转移到可以移植到土壤中的位置。该器件由路径发生器、拾取引脚和引脚驱动器组成。轨迹发生器是由固定槽、主动杆、从动杆、连杆和滑块组成的五杆机构。滑块被约束为沿着从动连杆和组合直线和圆形路径的固定槽移动。连接杆连接传动杆和滑块。当滑块沿着槽的直线路径移动时，它从单元格中取出一个幼苗。当它沿着圆形路径移动时，它将秧苗转移到移栽料斗。滑块是拾取销和销驱动器的组装件，它们是装置的组成部分。操作参数，如苗龄，针的接近方向，针到细胞的穿透深度，持苗方法，和提取速度进行了检查使用原型。该装置每分钟提取30株幼苗，使用23天龄的幼苗，成功率为97%。
A new seedling pick–up device for vegetable transplanters was developed and evaluated in a laboratory. The pick–up device extracts seedlings from a 200–cell tray and transfers them to a position from which they can be transplanted into the soil. The device consists of a path generator, pick–up pins, and a pin driver. The path generator is a five–bar mechanism comprised of a fixed slot, a driving link, a driven link, a connecting link, and a slider. The slider is constrained to move along the driven link and a fixed slot of combined straight–line and circular paths. The connecting link joins the driving link and the slider. When the slider moves along the straight–line path of the slot, it takes a seedling from a cell. When it moves along the circular path, it transfers the seedling to the transplanting hopper. The slider is an assemblage of pick–up pins and a pin driver, which are integral parts of the device. Operational parameters such as seedling age, approach direction of the pins, penetration depth of the pins into the cell, seedling holding method, and extracting velocity were examined using a prototype. The device extracted 30 seedlings per minute with a success ratio of 97% using 23–day–old seedlings.
