| Abstract: | For sowing single high quality hybrid paddy rice seed,a new type of precision sowing scheme was put forward,which feed seeds by electro-vibrating method,select single seed by special seed selection mechanism,adsorb seed by vacuum pressure,and eject seed by positive pressure. Based on detail structural design of the seed feeding mechanism,the seed selection mechanism,the suction and ejection mechanism,and the pneumatic control system,a experimental platform was established. Experiment research of different t... |
