The utility model discloses a multi-stage raw coal sorting machine. Jigging box, n partition plates are movably mounted in the jigging box; the jigging box is divided into n + 1 jigging pools by the partition plates; the two sides of the partition plate are connected with vibration springs through connecting pieces. The n partition plates are connected through connecting plates. The connecting plate is movably matched and connected with the cam rod; the middle part of the cam rod is also sleeved with a pair of jigging connecting rods; the ends, away from the cam rods, of the jigging connectingrods are movably connected with jigging plates correspondingly. A liquid injection port is formed in the jigging box on one side of the blanking plate; a liquid outlet is formed in the end, away fromthe liquid injection opening, of the jigging box. Liquid in the jigging pool is vibrated by turning over the jigging plates, then raw coal jigging separation work is completed, the jigging mode and the structure are simple, m
