摘  要：
The difficult problems and keys on separating in the mechanization of potato digging were indicated and the calculating model of the vibrating sieve to design digging components by Visual Basic 6.0 was also established based on our national conditions.Visual Basic 6.0 was used to program the procedure.Mutual action course was analyzed and moving rule was studied with the ideas and methods of designing new components through CAA,the moving process was also simulated.The moving mechanism and moving state of the tubers on the sieve has been shown and was fully understood.The parameter optimum was carried out and performance was analyzed from the point of enhancing the efficiency of sifting and reducing the damaged rate and the working efficiency and productivity was enhanced.
