丸粒化玉米种子精密排种器
Precision Seed-metering Device for Pelleted Corn Seeds
摘要
Abstract
In order to solve the problem of mechanical precision metering, such as being strict with the size of seeds and high damage to seeds, a precision metering was designed based on the pelleted corn seeds. A single ( precision ) seeder experimental method, with the pelleted fcom seeds whose size approximatively follow the normal distribution N ( 13. 9, 0. 0566 ) , comparative experiments of the metering performance were conducted by changing the structure parameters and rational speed of the moving plate. The results indicated that the single seed index was more than 98% when the rational speed of the moving plate was 14 r/min, the diameter of the cell was IS mm and the oblique angle was 23°, so it proved that it had high sowing precision and speed.关键词
