Experimental Study on Electromagnetic Vibrated Seeding Apparatus of Rice Direct-seeding Machine

In order to improve the seeding uniformity of electromagnetic vibrated seeding apparatus, an indoor physical experiment was carried out on the main affecting factors for the seeding consistency by means of the quadratic general rotary unitized design. Then, by using the statistical analysis, mathematical model establishment and computer optimization technique, the corresponding mathematical model was established. The influence mechanism of the structure factors and the physics factors on the seeding uniformity was analyzed and the optimization parameter on the main affecting factors for the seeding consistency was confirmed. This research also has important reference value for the improved design and study of electromagnetic vibrated seeding apparatus.
