Design of intelligent selection system for agricultural by-products

Aiming at the pod kind of agricultural by-product high cost problem which is led by low automation and the need for more people,intelligent selection system for pod kind of agricultural by-product was designed.This system was composed of material conveying mechanism,image acquisition device,an image processing system,photoelectric sensor,PLC,electromagnetic valve,high pressure nozzle and clean compressed air.The test device based on the system was designed and made.In the practical application process,the conveying mechanism,the image acquisition device and a series of valves were controlled automatically by the system.The required material was removed effectively by the high pressure gas erupted from the air cock.The results indicate that the precision of this automation technology for the selection of the kind of agricultural by-product can get 95.67%.
