Description

Technical Field

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

[0002] Disc harrows are traditional tillage tools used in agricultural production. In agricultural planting, disc harrows are generally used to loosen the soil and remove weeds. In order to adapt to different planting needs, disc harrows are usually designed with adjustable spacing to facilitate loosening and weeding of the soil, thereby ensuring that crops are planted on the land.

[0003] In the Chinese patent with the announcement number CN219205150U, a light disc harrow is disclosed. The light disc harrow reduces the weight of the overall structure of the disc harrow by providing a fixing plate and a traction rod. The light disc harrow is suitable for shallow tillage and stubble removal of land, and is convenient for workers to operate the disc harrow. The disc harrow blades are detachably connected to the mounting shaft. The workers can adjust the number of disc harrow blades on the mounting shaft according to the width of the soil to be plowed, thereby improving the adaptability of the overall structure of the disc harrow. However, in actual use, the above-mentioned light disc harrow is generally installed by the disc harrow blades and the mounting shaft, and then installed with the agricultural machinery through the positioning plate. However, after the disc harrow blades are loosened, it is difficult to quickly remove the positioning plate from the agricultural machinery, thereby making it inconvenient for workers to quickly disassemble and assemble the positioning plate and the disc harrow from the agricultural machinery. This reduces the speed of disassembling and assembling the positioning plate and the disc harrow from the agricultural machinery, making the installation of the positioning plate and the disc harrow time-consuming and labor-intensive, reducing the efficiency of disassembling and assembling the disc harrow, and affecting the practicality of the disc harrow.

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