Abstract:A piezoelectricity vibration table was designed for seeding precisely the small size of seeds of some vegetables, trees, flowers, etc. The piezoelectric vibration driving system produced the mechanical micro displacements with the applied electric field. The micro-displacements amplified by the amplification mechanism drove the seed dish vibrating and produced the boiling movement beneficial to suck seeds. The mathematical model of piezoelectric vibration was established. The static and dynamic state properties of the variation table were analyzed and experienced. The experimental results showed that the piezoelectric vibration system had a higher drive capacity with 90~110V electric voltage. Vibration amplitude achieved 131mm, vibration frequency was at 13~55Hz and adjustable (resonant frequency of 25Hz). The piezoelectric vibration table has better characteristics and higher seeding performances. It runs smoothly and meets the agronomic demands for precise tray seeding.
