The utility model discloses a garlic flake directional control device which is arranged on a garlic planting machinery and comprises a cone garlic flake guide pipe with a big upper part and a small lower part. A closed compressed air cavity is arranged around the outer periphery of the cone garlic flake guide pipe. The outer wall of the compressed air cavity is provided with an air inlet. The pipe wall of the cone garlic flake guide pipe is provided with a garlic flake guide air hole communicated with the compressed air cavity. The air outlet direction of the garlic flake guide air hole is inclined upwards. Due to the utilization of a certain flow and flow rate of air, garlic flakes are in a semi-suspended state; the garlic flakes descend slowly under the action of the air; and upward garlic tips is realized better in the falling process of the garlic flakes by the structural characteristic of lower gravity centers of the garlic flakes under the action of the air, so that the erectness percentage of the garlic flakes is greatly improved, and thus, the directional problem in the garlic planting is further solved. Due to the adoption of the garlic flake directional control device, the erectness percentage of the garlic flakes is greatly improved, the operation labor intensity of workers is reduced, the productivity is improved, the garlic flake directional control device is convenient to use, and the labor cost is reduced.
