Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a furrowing and ridging mechanism for crop planting. Background Art

[0002] Furrowing and ridge formation is a key land preparation technology in agricultural production. It achieves multiple agronomic goals by constructing furrow and ridge structures: improving soil drainage and avoiding waterlogging; increasing soil temperature and promoting crop root development; and facilitating field management such as irrigation and fertilization. Its standardized operation process includes: planning and measurement - determining ridge height, ridge spacing and furrow depth parameters based on crop needs; furrowing - using hoes, plows or special machinery to dig furrows; ridge formation - turning the soil in the furrow to both sides to form a ridge body, and compacting and leveling it.

[0003] This technology relies on ridging machines to achieve efficient operation. As a special agricultural machinery, ridging machines can greatly improve the planting efficiency of crops such as vegetables, potatoes, and corn. There are two main types of ridging machines: hand-held and suspended. Among them, the hand-held ridging mechanism is compact and suitable for small plots such as greenhouses and hills; the suspended ridging machine relies on tractor power and is suitable for large-scale operations in medium and large farmlands.

[0004] At present, there are still the following technical bottlenecks in the practical application of ridging machines: 1. Insufficient soil adaptability: Heavy clay soil is prone to soil blockage, and sandy soil has poor ridge stability; 2. Lack of single-unit regulation: It is impossible to independently regulate a single group of mechanisms when multiple trenches are operating simultaneously, making it difficult to adapt to complex terrain such as slopes, resulting in excessive energy consumption; 3. Low functional integration: Most models are limited to ridging operations, and it is urgent to develop integrated ditching-riding-covering equipment; 4. Poor transportation convenience: Large suspended models are difficult to transfer, and small equipment cannot meet the needs of deep trenches and high ridges, so the structure needs to be optimized through modular design.
