Technical Field

[0001] This utility model relates to the field of sowing technology, and in particular to an automatic water replenishment device for trench sowing. Background Technology

[0002] Compared to traditional drip irrigation and flood irrigation methods, automatic water supply devices for trenching and sowing can significantly reduce irrigation water consumption, achieving water-saving and high-efficiency results. This allows seeds to absorb enough water to germinate and emerge, and the device is also cheaper.

[0003] Automatic water replenishment devices are mostly installed on the seeder and move with it. After sowing, they open furrows to replenish water and then backfill. Due to geological differences, some soils are loose and some soils are hard and compacted. Some devices cannot adjust the depth of the furrowing blades or the position of the backfilling baffles, which limits their use.

[0004] Therefore, those skilled in the art have provided an automatic water replenishment device for trenching and sowing to solve the problems mentioned in the background art. Utility Model Content
