Problems solved by technology

[0004] The object of the present invention is to provide a depth-limiting ground wheel aimed at the deficiencies described in the background technology. The depth-limiting ground wheel adopts a combined structure to adjust the depth of the ground wheel. The rapid adjustment of the range can also be adjusted accurately, which is used to solve the technical problems of the traditional depth-limited ground wheel, such as low adjustment accuracy of stepped adjustment, small adjustment amount of stepless adjustment, long adjustment time, and low use efficiency

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a depth-limiting ground wheel. Background technique [0002] Depth-limiting ground wheel is a commonly used part of agricultural machinery. The depth-limiting ground wheel directly affects the working depth of the tillage equipment, and often needs to be adjusted continuously according to the actual surface conditions to ensure the best tillage quality. Most of the existing depth-limiting ground wheels use a single pin-hole with stepped adjustment or screw-type stepless adjustment, but both methods have disadvantages. Although the pin-hole fit is convenient and quick, it cannot be adjusted accurately. Although the adjustment amount of the screw type adjustment method is relatively accurate, the adjustment amount is small each time, and it often takes a long time to adjust to the required depth, which directly affects the use efficiency of the equipment. [0003] ...
