The present invention relates to a multi-screen sorter for a grain sorting machine which comprises a fixed screen (10) with first holes (12); a moving screen (20) which has second holes (22) and is installed at the upper part of the fixed screen (10) to move up and down; and sorting holes (30) which are formed in spaces in which the first and second holes (12, 22) are overlapped as the moving screen (20) closely adheres to the fixed screen (10). Therefore, according to the present invention, when sorting subjects are stuck in the sorting holes (30), the subjects can be removed easily through the first holes (12) and the second holes (22) which are individually extended by the up-and-down movement of the moving screen (20) as the sorting holes (30) are formed in spaces in which the first and second holes (12, 22) are overlapped. |
