| Abstract: | According to the development trend of crop fertilization and irrigation integration in modern agricultural production,this paper studies the key part of the water and fertilizer integrated fertilizer applicator,the structural design of the suction system and the fat absorption of the suction channel.A three-channel suction system for water and fertilizer integrated fertilizer applicators based on parallel flow of jets was designed.The three-dimensional structure of three-channel suction system for water and non-integrated water and fertilizer integrated fertilizer applicators was established through SolidWorks three-dimensional software,and the application performance of FloEFD to the suction system was evaluated.Perform simulation analysis.Five kinds of boundary condition schemes were constructed to carry out the simulation and analysis of sucking fertilizer performance.The performance test was conducted with an inlet pressure of 0.5Mpa and an outlet pressure of 0.1MPa.The results showed that the suction fertilizer system can achieve up to 98.1%of suction accuracy for each channel.At the same time,the controller and the mechanical parts of the pipeline were designed for the variable absorption of the three suction channels,and the feasibility was verified by experiments.It provides a reference for the in-depth research and development of water and fertilizer integrated fertilizer applicators. |
