Structure Design and Modeling Simulation Analysis of Flexible Brush Type Wolfberry Harvesting Machinery
A kind of riding straddle type wolfberry harvesting machinery with flexible rotary comb brush harvest as the working principle was designed,which was composed of picking device,collection device,transmission structure,walking device,frame and other parts.Theoretical-ly,it can implement picking wolfberry,low-loss collection,cleaning and other functions at once.SolidWorks software 2022 was used to com-plete the 3D modeling,and Ansys Workbench 2022 software was used to conduct the finite element simulation experiment on the core compo-nent brush component.The results showed that the maximum strain of the frame was 58.79 MPa,which was smaller than the yield strength limit of the materials.And the maximum strain variable was 0.0003 mm,which could meet the strength requirements of the materials.The free mode analysis results showed that the inherent frequency of the first 3 modes was almost zero,which was manifested as rigid body mode.Starting from the fourth mode,it was manifested as elastic mode.The frequency of the first 10 modes gradually increased,and the highest value was about 9.4700 Hz,which was quite different from the machine frequency,which verified the rationality of the structure scheme and material selection design of the whole machine.The design of the harvester could provide references for further study of low-damage mechanized harvesting of wolfberry.
