Sweet potato seedling transplanter

The invention relates to the technical field of transplanting machines, and provides a sweet potato seedling transplanting machine which comprises a material conveying mechanism arranged between two side plates, sweet potato seedlings are intermittently conveyed through the material conveying mechanism, and a transplanting mechanism is arranged on the front side of the material conveying mechanism; by means of the transplanting mechanism, sweet potato seedlings conveyed on the conveying mechanism can be pulled out and planted at the angle of 45 degrees, operation is easy, the structure is ingenious, automatic oblique transplanting planting of the sweet potato seedlings can be achieved, the working efficiency is greatly improved, and the labor intensity is reduced. A tamping mechanism is arranged on the U-shaped frame, after sweet potato seedlings are planted by the transplanting mechanism, the tamping mechanism can automatically compact a soil layer above the planted sweet potato seedlings under the transmiss
