Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery and equipment, and specifically belongs to an agricultural soil-turning device. Background Art

[0002] Agricultural soil-turning devices are important mechanical equipment in modern agriculture, mainly used for soil tillage, loosening and improvement. Its core functions include tilling the soil to improve its structure, breaking up soil clods to form fine soil, mixing fertilizers and pesticides to increase fertility, and promoting the activities of soil microorganisms. Soil-turning devices are widely used in horticulture, farmland tillage, land improvement and pre-planting preparation work, improving soil quality and planting conditions. Soil-turning devices are usually powered by agricultural machinery such as tractors, using rotary blades or shovel blades to turn over and break up the soil. Some soil-turning devices are equipped with depth adjustment devices that can adjust the tillage depth as needed. Compared with traditional manual tillage, soil-turning devices have significant advantages in terms of efficiency and can complete large-area tillage tasks in a short time. They are highly adaptable and can handle various types of soil, including clay, sandy soil and loam. The design of modern soil-turning devices also focuses on easy maintenance and environmental protection. Some new devices use low-noise and low-emission technologies to meet environmental protection requirements. All in all, agricultural soil-turning devices have become an indispensable equipment in modern agriculture by improving soil quality and tillage efficiency. With the continuous progress of technology, their performance and functions are also continuously improving, providing stronger support for agricultural production. However, current agricultural soil-turning tools are mainly integrated, and most designed hoes are blade-type. With the drive of the engine, the tool also rotates. In such a designed soil-turning tool, the drive device is above the blade, and the blade bears the weight of the entire device and the drive engine, resulting in a large and bulky body. When the soil-turning device is working, due to the rotation of the soil-turning blade, strong vibrations are generated at the hand-held handle, causing a numb and uncomfortable feeling in the user's hand. In addition, the current soil-turning device has a fixed soil-turning width during the working process, and it is impossible to reach and turn over the soil in narrow places or on slopes.

[0003] Existing agricultural soil-turning has certain drawbacks when in use. It is large in size and heavy in weight, making it inconvenient to carry in rugged mountainous areas.
