The invention discloses a depth-limited land wheel, and belongs to the technical field of agricultural machinery. The depth-limited land wheel comprises a welding support, a lead screw and adjusting outer sleeve combination, a fastening device combination and an adjusting inner sleeve combination. According to the land wheel, limited depth of the land wheel is adjusted by the aid of a combined structure, the land wheel and a tillage implement are used in a matched manner, rapid adjustment of wide ranges can be implemented, and accurate adjustment can be implemented. The land wheel adapts to operation in flat lands and also adapts to depth-limited operation in uneven lands such as edge of a field and slope lands, and the land wheel has the function of improving operation efficiency and quality of the tillage implement.
