Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a furrowing device used for preparing furrows in seed beds. Background Art

[0002] In the unique climate region of the Yangtze River Basin, the abundant rainfall brought by the monsoon climate makes the suitable sowing period for many vegetable crops coincide with the rainy season. During this period, the soil moisture content increases significantly, and the soil becomes sticky and wet, which brings great challenges to mechanized sowing operations. When the seeder is in operation, its tools are very likely to adhere to the wet soil, which not only increases the working resistance, but also seriously affects the uniformity and depth control of sowing, resulting in a significant reduction in sowing quality, which in turn affects the growth and yield of subsequent crops.

[0003] In order to cope with this problem and improve the mechanization level and efficiency of vegetable planting, many farmers and agricultural technicians began to explore ways to open furrows on both sides of the seedbed. These furrows can not only effectively drain water, reduce soil moisture, and prevent crops from suffering from waterlogging due to accumulation of water, but also maintain soil permeability and promote the development of crop roots. However, due to design limitations, traditional plowshares are often difficult to operate stably in wet and sticky soils during the furrowing process, and soil backflow and irregular furrow shapes are prone to occur, making it difficult to meet the needs of precision agriculture.
