Extrusion roll is one of the key components of QW-QZ-2 type seed crushing and separating machine,which significantly affects the crushing and separating effect of Seed-used watermelon.In order to study the mechani-cal characteristics of the extrusion roll in the working process,the finite element analysis of the extrusion roll of the QW-QZ-2 type seed extractor was carried out by using ANSYS software.The results show that the maximum deform-ation of the extrusion roll occurs at the edge of the extrusion roll,which is 1.03×10-2 mm,the maximum strain varia-ble is 1.0638e-5mm,and the maximum stress at the connection between the extrusion roll and the support shaft is 2.121 7 MPa.The maximum deformation and maximum stress are far less than the stiffness strength of SUS304 materi-al,which meets the working requirements of the extrusion roll.The research can provide a theoretical basis for the design and optimization of the crushing and separating parts of the seed extractor.
