摘　　要：钵苗移栽技术是一项现代农业增产技术,在国内外得到了广泛应用。在钵苗移栽作业过程中,大部分采用的是人工作业的方式,这种作业方式作业效率低,并且对苗的损害较大。为了提高钵苗移栽的自动化程度,设计了一种新的基于PLC的蔬菜钵苗移栽机自动制钵和输送装置。该装置采用PLC控制系统,利用伺服电机和步进电机可以实现高精度秧苗的推出和准确定位,降低了秧苗的损失。利用带传动和齿轮传动实现了转筒和栽植器的同步。最后,在实验大棚对穴盘钵苗自动输送装置的效果进行了测试,为了验证试验机的效果,将人工实验结果和试验机测试结果进行了对比。结果表明:采用基于PLC控制系统蔬菜穴盘钵苗机的移栽作业和人工方式相比,蔬菜苗损失率有所下降,成功投苗率提升,从而验证了装置的可靠性。The seedling transplanting technology is home and abroad. In the process of transplanting which has low efficiency and great transplanting, based on PLC high precision damage a modern agricultural production technology, has been widely used at seedling transplanting, most of the methods used are manual work, to the seedlings. In order to improve the automation degree of the pot seedling a new type of automatic bowl and conveying device for the vegetable bowl seedling transplanting machine was designed. The device adopts the PLC control system, the servo motor and seedling launched and accurate positioning, reducing the loss of rice seedlings step into motor can realize . Using the belt drive and gear transmission to realize the synchronization of the drum and the planting device. Finally in an experimental green- house seedlings automatic conveying device were tested, in order to validate the experimental machine effect, the artifi- cial experimental results and testing machine test results were compared, by the test results show that the based on PLC control system vegetable plug seedling machine transplanting operation and manual methods compared, vegetable seedling loss rate declined, dropping seedling rate increase, which verified the reliability of the device.
