Optimization experiments on electromagnetic vibrated seeder of rice bud-seed for field seedling raising
摘要
Abstract
In order to study the influence law of electromagnetic vibrated seeder for field seedling raising of rice bud-seed's performance and obtain the optimal combination of parameters, single factor and multi-factor experiments were carried out on seeder for field seedling raising of rice bud-seed. The relationship of the four influencing factors (opening height of retaining plate, walking speed, vibration velocity of seed plate and stiffness of vibration isolating rubber pad) and seeding quantity and seeding pass rate were established respectively by regression analysis. The influence law and mechanism of the factors and their interaction were analyzed, and the respective optimization of the parameters was obtained. The results showed that: opening height of retaining plate is less than 7mm, blocking phenomenon was serious; when opening height of retaining plate and vibration velocity of seed plate was big, seeding quantity and the pass rate of seeding was high, and when walking speed was large, seeding quantity and pass rate of seeding was low; combination of small walking speed and large vibration velocity of seed plate was beneficial to improve pass rate of seeding. Optimal combination of parameters was achieved under the condition that opening height of retaining plate was 9.3 mm, walking speed was 50.1 mm/s, vibration velocity of seed plate was 13.1 m/s, and stiffness of vibration isolating rubber pad was 1248.9 N/mm. The pass rate of seeding interval with 95% reliability was from 86.72% to 93.54%. This paper provides a foundation for optimization design of seeder.关键词
