The utility model belongs to the technical field of agricultural machinery and relates to a seed discharging device of a hill planter; the seed discharging device disclosed by the utility model comprises a rotating shaft and a movable disc arranged on the rotating shaft; duckbilled dibblers are uniformly arranged on the circumferential wall of the movable disc; an inner disc is coaxially arranged in the movable disc; a fixed disc is arranged at one side of the inner disc; the inner disc and the fixed disc form a seed chamber; seed discharging grooves corresponding to the duckbilled dibblers are formed in the circumferential wall of the inner disc; a rotary cover is arranged on the seed discharging hole of each seed discharging groove; and protruding blocks corresponding to the rotary covers are arranged at the lower end of the fixed disc. The seed discharging device disclosed by the utility model is simple in structure, reliable to work and reasonable in design; seeds are fetched in advance through the seed discharging grooves distributed on the circumferential wall of the inner disc; then, the seeds are fed into the duckbilled dibblers to be discharged by controlling the rotary covers on the seed discharging grooves; therefore, the seeds can be fed into the duckbilled dibblers in time; the problems of non-uniform seed discharging, re-seeding and omission can be solved well; a baffle is used for blocking redundant seeds in the seed chamber, so that redundant seeds are prevented from being discharged after the rotary cover is opened; and the seeding precision is ensured.
