Abstract: In harvesting process of leafy vegetables，it is difficult to achieve mechanical screening because that the leaves are relatively fragile.The traditional production method is to remove waste leaves，shake off roots，soil impurities，comb and stamp by a large number of workers at the same time，so as to carry out subsequent packing or bundling.This kind of harvesting method is time-consuming and laborious，and it is difficult to guarantee same finishing quality after harvesting.Based on this，in the design process of leafy vegetables intelligent harvester，undulating vibration carding mechanism was specially designed.After harvesting，vegetables were transported to sieve plate of vibration carding mechanism through transmission device，and movement of vibration motor was used to shake off waste leaves and soil at root of vegetables.Through carding mechanism driven by reduction motor，carding of vegetables and orderly stamping of roots were completed.
