The utility model discloses a multistage sample dividing device. The device comprises a sample dividing case, wherein a material inlet is formed in the upper end of the sample dividing case, and a material outlet and a sample receiving opening are formed in the lower end of the sample dividing case. The device is characterized in that a plurality of sample dividing boxes are successively arranged in the sample dividing case from top to bottom in an interlaced manner,a uniform dividing device is arranged in each sample dividing box, the lower side of one sample dividing outlet of the first sample dividing box is arranged right against a sample dividing inlet of the second sample dividing box, the other sample dividing outlet of the first sample dividing box is communicated withthe material outlet formed in the bottom of the sample dividing case through an opening of the sample dividing box, the lower side of one sample dividing outlet of the second sample dividing box is arranged right against a sample dividing inlet of the third sample dividing box, the other sample third outlet of the second sample third box is communicated to the material outlet formed in the bottom of the sample third case through an opening of the sample assorting box, the later operation is performed in the same manner, and through successive dividing, one sample in a sample collecting box is finally obtained. The device totally replaces human power to divide samples, so that sample dividing efficiency is high, sample dividing is uniform, working environment is optimized, samples are mechanically divided, the sample dividing process is completed at one time, and the index of a sub-sample is consistent with the index of a gross sample.
