There are a lot of problems in deep application-type liquid fertilizer such as large energy loss, low efficiency, transporting liquid fertilizer hose winding, etc, because of intricate piping in splitter and fertilization institutions of deep application-type liquid fertilizer. Hence, we designed a rotor type liquid fertilizer converter by theoretical analysis and Adams simulation method in order to solve the above problems. Using the converter, which could replace original splitter and any original tubing of fertilization institutions, we designed the pipe system of transporting liquid fertilizer. We used the new pipeline system with the converter in an anti-winding test. We also used the new one and the original pipeline for a comparative fertilization experiment. When finished the anti-winding experiment we found that when the sun gear and the planetary gear ratio was 3∶1 and the sun gear and the planet carrier speed ratio was 2∶3, the converter applications could better solve the transporting liquid fertilizer hose winding problem of fertilization institutions. When finished the comparative fertilization experiment we found that the new pipeline system efficiency was 2.63 times of the original pipeline system when fertilizer was 20.32 mL/time and pump pressure was 0.31 MPa.
