The invention belongs to the technical field of breaking and sorting devices, and particularly relates to a scrapped vehicle breaking and sorting device. The scrapped vehicle breaking and sorting device comprises a shell, a feeding hopper, a breaking roller, a breaking stand column, a draught fan, a grinding module, and a strong magnet; a set of V-shaped protrusions are arranged on the plane of the upper end of the right side of the breaking stand column, a grinding block is fixedly connected to each connecting support on the chain, a breaking object is ground into small particles, the grinding efficiency is high, a set of rectangular through grooves are horizontally formed in the arc face on the lower end of the right side of the breaking stand column, rapid separation of metal and plastic can be achieved, because the breaking object rolls along the arc face, the breaking object can be evenly scattered, metal and plastic are better in separation effect, the cylindrical strong magnet is embedded on the right side wall of the lower end of the shell, small metal included in the plastic can be attracted by the strong magnet, and the metal and the plastic can be more thoroughly separated.
