Disclosed is a multi-specification efficient grain counting machine. The multi-specification efficient grain counting machine comprises a material box and a grain counting disc, wherein the grain counting disc is arranged in the material box. The material box comprises a shaking area, a grain guide area and a rotating shaft, wherein the grain counting disc is held in the shaking area, the grain guide area is arranged below the shaking area, and the rotating shaft is arranged in the shaking area and is used for being connected with, fixing and rotating the grain counting disc. The grain counting disc comprises a first grain counting unit, a second grain counting unit, a third grain counting unit and clamping fixing blocks, wherein the second grain counting unit is arranged at the periphery of the first grain counting unit, the third grain counting unit is arranged at the periphery of the second grain counting unit, and the clamping fixing blocks are used for connecting the first grain counting unit with the second grain counting unit or connecting the second grain counting unit with the third grain counting unit. According to the invention, the number of grain falling holes can be determined through the control over the positions of the three grain counting units, and therefore the requirement for adjusting different packaging grain numbers can be met, the purpose that the machine has a plurality of purposes is really achieved, energy is saved, and the efficiency is high.
