摘　　要：设计了一种基于PLC的蔬菜钵苗移栽机自动输送装置。采用高速伺服电动缸驱动推杆顶出秧苗的方式,实现了高速精准无损伤取苗;通过PLC控制系统控制步进电动机,实现了钵苗的精准定位和输送;设计了同步带及齿轮传动的同步投苗装置,实现了投苗转筒与鸭嘴栽植器完全同步,解决了地轮驱动的鸭嘴栽植器在栽植过程中转速不均匀的问题,提高了投苗的准确率。最终设计了试验台,验证了钵苗自动输送装置的可行性。An automatic delivery mechanism of potted-seedling for vegetable transplanter based on PLC was designed.The automatic mechanism of taking potted-seedling from pot with non-damaging was designed.The ejector pin driven by high speed servo electric cylinder was used.The potted-seeding was taken from the pot with precise,high speed and non-damaging.The potted-seedling was located and transplanted precisely by the stepping motor which was controlled by the software system of PLC.The casting potted-seedling mechanism synchronously,consisted of the timing belt and gear,was designed,which realized the synchronous movement between the casting potted-seedling unit and the duckbilledtype planting shoe.The problem of non-uniform rotation velocity of duckbilled-type planting shoe driven by ground wheel was solved.The seedling accuracy was increased.At last,the device was designed,which verified the correctness of automatic delivery mechanism.
