Abstract

Abstract: In order to improve the fertilization efficiency of corn fertilizer applicator in the Huang-Huai-Hai area, according to the requirements of the wide-row crop fertilizer requirements, a centralized type fertilizer ejecting device was designed. Straight outer groove-wheel was regarded as research objects in this paper. The simulation model of fertilizer ejecting device was established and the simulation analysis of fertilizer ejecting was carried out by using the discrete element simulation software (EDEM). In the simulation environment, the requirement of fertilizer ejecting amount was 300kg·hm -2, the forward speed of fertilizer ejecting device was set to 5.4km·h -1, and the working height of fertilizer axis was 250mm. The effect of different working lengths of fertilizer ejecting wheels on the fertilizer performance was analyzed. The simulation results showed that when the working length of fertilizer ejecting wheel was 28mm, the uniformity variation coefficient of fertilizer ejecting was 14.62%, and the accuracy rate of fertilizer ejecting was 95.95%, which indicated that performance of fertilizer ejecting was better. This research results can provide references for the subsequent development of corn fertilizer applicator.
