Experiments on performance of rice bowl dish precision seeder in filling processing
Abstract:In order to optimize the parameters of rice bowl dish precision seeder, and improve its filling performance, filling experiment of seeder were conducted using self-developed rice bowl dish precision seeder by quadratic orthogonal rotary experiment with three-factor and five -level. The influences of shaped hole diameter, shaped hole thickness and seed boxes velocity on the rate of filling and the rate of cavity were investigated. The results showed that the sequences of factors, which influencing the rate of filling and the rate of cavity were shaped hole diameter, shaped hole thickness and seed boxes velocity. Optimal parameters of rice bowl dish precision seeder were as abstained that shaped hole diameter was 10mm, shaped hole thickness was 4mm, seed boxes velocity was 0.115 m/s. The research results can provide a reference for design and performance improvement of rice bowl dish precision seeder.
Keywords: bowl dish precision seeder quadratic orthogonal rotary experiment rice seed filling
