The grain storage barrels 10 are multiple, grains enter the grain storage barrels 10 respectively, a part of grains in the grain storage barrels 10 are mixed with stones, another part of grains in the grain storage barrels 10 are not mixed with stones, so that the weight of the two grain storage barrels 10 is different, when the centrifugal component 11 acts, the inclination degrees of the different grain storage barrels 10 are different, the inclination degrees of the grain storage barrels 10 mixed with stones are larger, the grain storage barrels 10 exceeding the preset inclination degrees are separated, the grains in the part of grain storage barrels 10 are conveyed to the centrifugal separation mechanism 2 for further centrifugal separation, and the rest part of grains are directly output to the clean grain collection box, therefore, a part of grains which are not mixed with stones can be distinguished before the stones are centrifugally separated, the grains in the part are not necessarily in the centrifugal separation mechanism 2, in addition, in the separation process, the collision strength between the grains is low, and the crushing condition caused by the collision of the grains can be reduced.
