Technical Field
[0001] The utility model relates to the technical field of disc harrows, in particular to a heavy-duty folding-wing disc harrow. Background Art
[0002] Disc harrow is an important agricultural machinery for farmland preparation. It is a tillage machine with a harrow group composed of multiple concave discs fixed on a horizontal axis as the working part. It is mainly used to loosen the soil after plowing to meet the agronomic requirements of land preparation before sowing. It is also used for weeding or shallow tillage and stubble removal on the stubble land after harvest. Heavy-duty disc harrows can also be used for arable land operations. Using disc harrows for land preparation can level the farmland, enhance the air permeability of the soil, and improve the soil's water storage and moisture retention capacity.
[0003] However, the above technical solution still has certain defects. During use, the discs used in the prior art are fixedly connected to a horizontal axis. Therefore, when facing soils of different hardness, the distance between the discs cannot be adjusted according to the hardness of the soil, resulting in insufficient flexibility during use. For this reason, a heavy-duty folding-wing disc harrow is proposed. Utility Model Content

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
