It is difficult to use a centrifugal distributor applying fertilizer on the steep grassland or on a field growing tall crops like maze. In order to develop a wide swath fertilizer spreader which throws granular fertilizer in a long distance by vertically turning blades, the theoretical analysis was made about the motions of fertilizer particles on the turning blades, and the flying trajectories of the particles.
The analysis of particle motions showed the leaving locations, outlet velocities and discharge angles of the particles from the turning blades, and the theoretical throwing distances of the particles. And the computer simulation predicted the optimum mechanical conditions to spread granular fertilizer on wide swath.
Based on the theoretical analysis, the data to design the wide swath fertilizer spreader were shown in this report.
