Introduction In order to improve the fertilizer-discharging uniformity of traditional spiral fertilizer distributor and achieve precise controllable fertilization, based on agronomic characteristics fertilization in pineapple orchards, a notched-blade discharger with mechanism discontinuous-blade sliding-cutting pushing-pore is innovatively designed. Methods Based parametric modelling determining volume accommodation spiral, theoretical amount determined combination analysis. The main factors influencing performance are analyzed using calculation formulas. discrete element method used simulate process. By comparing simulation experiments, it that has better than one. effects number shape periodic notched blades through single-factor experiments. L 9 (3⁴) orthogonal table adopted for conducting tests. Results test results show primary secondary influence indexes blade notch number. When sector, three notches, fluctuation coefficient discharge 27.01%. bench 27.42% when rotating speed 60r/min. experimental values consistent. Moreover, reduced by 64.86 percentage points compared under same conditions. 64.86% lower different rotational speeds, fitting curve y = 2.02 x + 23.02. Conclusion can be controlled adjusting speed. It improves accuracy application achieves goal green sustainable development industry tropics. research provide reference designing optimizing dischargers.
