摘要：

To improve the working efficiency of the cleaning device for maize mixture with a large feeding mass and to realize rapid dispersion of the maize grains on the sieve, a sieve with three-dimensional translational motion was designed based on a cylindrical cam. CFD-DEM (Computational Fluid Dynamics and Discrete Element Method) was used to investigate the motion of materials on the three-dimensional translational vibrating sieve (3TVS). The results show that the dispersion degree of transverse velocity of particles (DTVP) is correlated with the radius and rotation speed of the cam table and the height of the cylindrical cam positively. It is increased compared with the planar reciprocating vibrating sieve (PRVS). The effects of different factors on 3TVS cleaning device were obtained. This study provides a reference for designing a multidimensional-motion sieve for a large feeding-mass grains cleaning.
