Abstract:Pressing is an important part of precision seeding operation, which has an important effect on crushing soil. In order to enhancing the effect of soil crushing, some press wheels with flange rim are used. But further research is needed to evaluate whether the use of these press wheels affect the actual seeding depth that will affect precision seeding quality. Three kinds of press wheels, with the smooth rim, circular flange rim and rib rim respectively were designed, and the PFC3D discrete element method (DEM)… Show more
