Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery technical field, concretely is a plough. BACKGROUND

[0002] In the modern agricultural production system, ploughing operation as the key starting step of the cultivation process plays a decisive role in the whole growth cycle and final harvest of crops. High-quality ploughing operation can loosen the soil, improve the aeration, regulate the soil temperature and humidity, and also can lay a solid foundation for subsequent sowing, fertilizing and other agricultural activities.

[0003] For a long time, the traditional plough occupies a dominant position in agricultural production, and the ploughing teeth equipped with it are mostly fixed structure. With the development of agricultural refinement, the disadvantages of such fixed structure ploughing teeth are increasingly prominent. The soil conditions are complex and changeable, from sandy loam with loose texture and distinct particles, to clay with great viscosity and difficult to plow, to stony soil mixed with a large amount of gravel, different soil types test the performance of ploughing teeth differently. In the sandy loam environment, the conventional ploughing teeth can still cut into and turn over the soil smoothly with low resistance, but once they encounter clay, the high adhesion force will tightly wrap the blade, not only significantly increasing the difficulty of entering the soil, but also making the turned soil clump, making it difficult to achieve the ideal fine and loose effect. When it comes to stony soil, hard stones frequently impact, which can easily cause the ploughing teeth blade to crack and wear out, greatly shortening its service life. In addition to the difference in soil types, the diversified planting needs of crops also bring great challenges to the traditional plough. For example, lettuce, spinach and other shallow-rooted vegetables require fine and shallow plowing of the soil surface before planting to form a fine and uniform seedbed; on the contrary, fruit trees, sugarcane and other deep-rooted crops require deep plowing to ensure that the roots can fully stretch, with a depth of tens of centimeters. Therefore, the fixed structure ploughing teeth cannot adapt to different soil types and cannot accurately meet the diversified agricultural planting needs.

[0004] In summary, the existing agricultural production practice urgently needs to provide an innovative plough, which should have a design that can flexibly replace the ploughing teeth to comfortably cope with different soil characteristics and crop planting requirements, fill the gap in the current agricultural refinement operation equipment, and help agricultural production move to a higher quality and more efficient development stage.
