Design and Experiment of Quantitative Seed Metering Device for Cabbage Seeds Based on Gradually Changing Pitch
摘要
Abstract
To improve the fluency and quantitative accuracy of precision sowing of cabbage seeds,a quantitative seeding device based on a gradient pitch spiral rod was designed utilizing theoretical analysis and performance testing.First,the structure of the quantitative seeder was designed,followed by the analysis and calculation of relevant parameters;orthogonal simulation experiments and operational parameter optimization were conducted using Adams software.The results indicated that the optimal parameter combination for the cabbage seed precision metering device was the use of a gradual-pitch screw auger combined with a seed groove volume of 8 mm³ in the rotating disc.With this optimal parameter combination,the pass rate for cabbage sowing reached 89.6%.Above results provided new seeding device to address the issues of blockage and low quantitative accuracy in cabbage seed sowing and served as a reference for related research.关键词
