有机肥复合肥配比条施施肥机设计与试验OA

Aiming at the problems that the existing fertilizer discharger cannot be applied to the mechanized fertilization of high water content powdery organic fertilizer and the single function of the existing fertilizer applicator,a powdery organic fertilizer strip fertilizer applicator was designed.The fertilizer machine is mainly composed of a fertilizer box,a shaftless spiral fertilizer discharger,a spiral conveying device in the fertilizer box,a furrow opener and an intelligent fertilizer adjustment device.The fertilizer machine can adjust the ratio of organic fertilizer compound fertilizer,fertilization depth and fertilization row spacing according to the agronomic requirements,and can complete many operations such as ditching,fertilization and soil covering at one time.It has high operation efficiency,wide applicability,reduces repeated operations and meets the requirements of conservation tillage technology.The field performance test of the fertilizer applicator was carried out.The results showed that the maximum value of the coefficient of variation of the consistency of the fertilizer discharge in each row was 5.24％,the maximum value of the coefficient of variation of the stability of the total fertilizer discharge was 1.87％,the maximum value of the coefficient of variation of the uniformity of fertilization was 6.04％,the maximum value of the broken rate was 0.53％,and the minimum value of the qualified rate of fertilization depth was 93.75％.All the properties meet the national standard requirements and agronomic requirements of fertilization machinery,and can be used for the ratio fertilization of powdery organic fertilizer and compound fertilizer.
