The utility model discloses a fertilizer ejecting device and belongs to the technical field of agricultural machinery. The fertilizer ejecting device comprises a fertilizer ejecting shovel, a fertilizer ejecting tube, a fertilizer ejecting cutter, a fertilizer ejecting shaft and a spreading device, wherein the fertilizer ejecting tube and the fertilizer ejecting shovel are vertically arranged, the fertilizer ejecting cutter and the fertilizer ejecting tube are in front and back parallel and are connected with the fertilizer ejecting shovel; the fertilizer ejecting shaft is arranged inside the fertilizer ejecting tube; the spreading device is connected with the bottom end of the fertilizer ejecting shaft in the fertilizer ejecting shovel; the upper part of the fertilizer ejecting shaft is connected with the fertilizer box and the lower part of the fertilizer ejecting shaft is in limited connection with a limit sleeve in the bottom of the fertilizer ejecting tube. By arranging the fertilizer ejecting shaft in the fertilizer ejecting tube, the fertilizer is driven to move down by virtue of the rotation of the fertilizer ejecting shaft so that the fertilizer is quickly discharged; the fertilizer is uniformly spread in the deep layer of the soil with a certain width by virtue of a spreading blade in the fertilizer ejecting shaft so that the fertilizer mobility is increased, the fertilizer is uniformly spread and the nutrient absorbed by the soil is balanced. The fertilizer ejecting device is especially suitable for the fertilizer with poor mobility.
