Design and Experiment on the Curtain-fall and Narrow Air-suction Board Precision Seeder for Tray Raising Seedlings
摘要
Abstract
Based on the curtain-fall and air-suction precision seeding principle, a new precision seeder with narrow suction board was designed to solve the problems of low sucking seed rate and productivity, high power consumption and noise existed in vibration air-suction precision seeding technology for raising seedling with wide suction board, the whole structure and working mechanism of the seeder were introduced, the key structures of the curtain-fall controlling device, sucking seed and air-distributed parts were determined. Seeding test of the seeder showed that curtain-fall and air-suction precision seeding technology utilizing self-vibration of precision seeding device was beneficial to improve sucking seed action, sucking seed rate was near to 100%, and the narrow sucking seed board with porous single-line structure could increase the continuity of precision seeding. The scope of the seeder was expanded to the irregular-shaped seeds with seeding rate up to 800 trays/h. In short, the design of the seeder is suitable for precision seeding in high velocity and efficiency, low power consumption.关键词
