Abstract

Abstract: The purpose of this paper was to find out the influence of blade inclination, number of blades and travel speed on the fertilization uniformity of centrifugal disc Panax notoginseng fertilizer machine on the slope at different levels, so as to provide a theoretical basis for the design and optimization of centrifugal disc Panax notoginseng fertilizer machine. The physical parameters of fertilizer particles were determined by standard screening method, slope method, fine sand filling method and other methods; the leaf inclination angle, number of blades, and travel speed were selected as factors, the coefficient of variation of fertilizer particles was used as the test index, and the orthogonal simulation test of the fertilization process was carried out by EDEM software. The results showed that when the blade inclination angle was -20°, the number of blades was 4, and the travel speed of the fertilizer applicator was 0.6 m/s, the smallest coefficient of variation of fertilizer particles was 16.73%. After analysis, the influence on the coefficient of variation of fertilizer particles was as follows： blades inclination> number of blades> travel speed,blades inclination and number of blades were significant factors, and travel speed was not significant factor.
