Nonuniform HVEF Seed Featured Machine Design

Seed selection is an important part to improve the quality of seed processing.According to the basic physical characteristics and aerodynamic characteristics of the seeds, design of filter type, winnowing, gravity and other types of traditional breeding machine, it is difficult to achieve objectives.which is improve seed purity, germination and seed vigor purposes.In high voltage electrostatic field, It produced a biological effect in the seed tissue,which is enzyme activity and membrane permeability is improved,there is a feature of quality seed permittivity less than one of poor quality seed,it makes high-quality seeds suffered electric field force and moved in the direction of the field is less than the distance of the poor quality of seeds.Base on which and differences in seed group vigor,study and design HVEF seeds featured machines.Through analysis and study biology effect, polarization principle, the kinematic and dynamic characteristics in high voltage electrostatic field act like seeds, using Matlab software to analyze the characteristics of the field strength of the electric field, design of inhomogeneous high voltage electrostatic field seed election system; and design of the seed material breeze cleaning system, optimize the structure parameters in Matlab software;complete machine design of the type of 5ZCD-2 HVEF seeds featured machine and set up three-dimensional model.
