The connecting portion 224 of the present embodiment is an elastic rod or a fourth hydraulic cylinder, and an elastic rod is generally adopted, so that after the fixed ring body 204 of the deep fertilization unit 200 is adjusted by the angle adjusting mechanism to rotate a certain angle, the lower end of the earthing portion is always contacted with the ground, so that the elastic rod is elastically deformed by a certain amount, and the earthing portion is ensured to backfill the soil turned up above the ground into the trench.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments.
