Vegetation Yarn Equipment Control System Integration And Development

In our country, land plant mode is the chief mode in lawn industry, which is obstructing the development of lawn industry. So, soilless planting technique which is power frugal, environmentally friendly and sustainable, will be a new direction. Based on previous researcher's result, a new soilless planting technique which is called as lawn nursery yarn was proposed. Lawn nursery yarn, which is better in performance/price, is produced on the special device according to given production technology. It comprises seeds and fertilizer, weeds inhibitor, etc planted in strip base in terms of rated density. It can be applied in road bank protection, city virescence, and building top floor virescence. It can also be used to protect ecological environment, reduce soil erosion and control sandstorm, etc. in the western and northern areas.At present, there is no machine which produces lawn nursery yarn at home and abroad. So we innovate a existing carding machine, and make it produce lawn nursery yarn. We designed a control system, which comprises human machine interface (HMI), programmable logic controller (PLC) and step motors, instead of the original control system. The modular control system can be achieved including seeds motor, drawing roller motor, feeding roller motor, spindle motor and ring motor, so that we can easily change equipment technical parameters and greatly improve automation of the machine.
