Technical Field

[0001] The utility model belongs to the technical field of disc harrows, and in particular relates to a disc harrow with a flushing function. Background Art

[0002] A disc harrow is a tillage machine with a harrow group composed of multiple concave discs fixed on a horizontal axis as its working parts. It is mainly used to loosen the soil after plowing to achieve the agronomic requirements of land preparation before sowing. It is also used for weeding or shallow tillage and stubble removal on the stubble after harvest.

[0003] In a Chinese patent with announcement number CN220383497U, a disc harrow that is easy to cultivate is disclosed. The structural design of the adjustment mechanism of the patent realizes that the relative positions of two groups of adjustment rods and the support frame can be adjusted by using the adjustment mechanism, so that the distance between the two support seats can be adjusted, and then the distance between the two groups of disc harrow bodies can be adjusted, so that the size of different farmlands can be adjusted; although the above-mentioned disc harrow that is easy to cultivate can adjust the distance between the disc harrow bodies, when the soil blocks after plowing are narrow and long strips, it is difficult to adjust the longitudinal angle of the disc harrow body, which makes it difficult for the disc harrow to crush the narrow and long strips of soil blocks, reducing the effect of loosening the soil and affecting subsequent sowing.

[0004] In order to solve the above problems, the present application proposes a disc harrow with a flushing function. Utility Model Content
