摘要
针对深施型液态施肥机中输肥管路错综复杂存在能量损失大、工作效率低、输肥软管缠绕等问题,采用理论分析与ADAMS仿真方法设计了一种液肥转子式转换器。采用可替换分配器及施肥机构中原有输肥管路的转换器设计了结构简单、工作效率高的输肥管路系统。对安有转换器的新管路系统进行了防缠绕试验,对新、原管路系统进行了施肥对比试验研究。结果表明,当太阳轮与行星轮齿数比为3∶1,太阳轮与行星架转速比为2∶3时转换器可较好地解决施肥机构输肥软管的缠绕问题;当施肥量为20.32 mL/次,液泵压力为0.31 MPa时,新管路系统的工作效率是原管路系统的2.63倍。
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 was20.32 mL /time and pump pressure was 0.31 MPa.
