Disc harrows are a rising star of farming machinery and are widely used in most countries and regions in the world. And it is getting higher and higher evaluation in tillage implements, and now in a considerable number of countries, the importance of disc harrow is no less than that of the share plow. The reason why the disc harrow can be rapidly developed and popularized is that compared with the plough, it requires less power, has high operating efficiency, and can "replace plowing with harrow", save energy, avoid over-ploughing the soil, and harrow After the soil can be fully mixed, it can promote the activity and chemical decomposition of microorganisms in the soil. It also has the advantages of strong stubble removal ability, good soil crushing effect, low working resistance, high production efficiency, low operation cost, good moisture conservation and improvement of sowing quality.
The disc harrow has a strong ability to cut soil and crush soil, and is suitable for soil preparation work on relatively heavy soil. Since the disc harrow can cut grass roots and stubble, and stir the topsoil, it can also be used for post-harvest applications. Shallow tillage and stubble removal. The disc harrow consists of a harrow group, a harrow frame and an adjustment mechanism. The work of the disc harrow is carried out by the harrow group, and the configuration of the harrow group has two types: the opposite type and the offset type. The harrow blade is worn on a square shaft and is the main component of the harrow group. Like the disc plough, it is also a spherical disc, that is, the soil is shallow, and the edge of the disc is ground into a cutting edge and has a certain concave ( Also known as curvature), its concavity affects the ability of the rake blade to enter the soil and break the soil. The rake blade with the same diameter has a strong ability to enter the soil and break the soil.
