Design of Film Breaking Device for the Rice Mulching Transplanter Based on Rigid-Flexible-Fluid Coupling
Aiming at the problem of high root injury rate due to the lack of film breaking device or unreason-able structure of the device,a film breaking device of rice film transplanter was designed,and a rigid-flexible-fluid coupling model was established by finite element method.The influence of each experimental factor on the evaluation index is analyzed,and the multi-objective optimization is carried out.The optimal structure and work-ing parameter combination of the film breaking device are obtained and verified by bench test.The research can provide theoretical basis and technical support for the structure optimization of the film breaking device of rice transplanter and the visual interaction analysis under the complex operation environment of rice film covering.
