The invention discloses a sand making machine for preparing pure machine-made sand concrete. The sand making machine comprises a base, a supporting frame is arranged on the base, a plurality of springs are arranged between the base and the supporting frame, a vibration exciter is arranged at the bottom of the supporting frame, a first supporting column is connected to the supporting frame, a filter plate is connected to one end of the first supporting column, and a limiting ring is arranged on the outer edge of the filter plate. Under the action of vibration, the movement of gravels is accelerated, larger gravels are filtered on supporting pieces, and smaller gravels and gravels leak to the supporting frame through leakage holes; the larger gravels can be filtered in a filtering frame by arranging the filtering frame, and the gravels meeting the standard can be discharged through meshes of the filtering frame; by arranging a guiding frame, under the vibration action of the vibration exciter, the gravels in th
