摘要
针对目前全自动移栽机作业效率低、稳定性低的问题。结合自主设计的全自动移栽机装置,基于可编程控制器PLC设计一种穴盘苗的取喂苗控制系统,并进行田间试验。试验表明,系统通过PLC控制多个气缸与步进电机,能够实现取苗、喂苗的协调配合。在移栽速率为60~120株/min范围内,取喂苗成功率与苗株完整率均大于95%。控制系统能适应不同移栽速率下的自动移栽作业,最终实现高效稳定自动移栽。
Aiming to solve the problems of low efficiency and low stability of the automatic transplanter at present, a picking and feeding control system of the cavity plate seedling combined the self-designed automatic transplanter device was designed using programmable logic controllers(PLC) and a field experiment was carried out. The experiment showed that the system could realize the coordination of picking and feeding seedlings through PLC control of multiple cylinders and stepper motors. When the transplanting rate was 60-120 plants/min, the success rate of feeding seedlings and the integrity rate of seedlings were both greater than 95%. The control system could adapt to the automatic transplanting operation under different transplanting rates, which realized efficient and stable automatic transplanting.
