Description

Technical Field

[0001] The utility model belongs to the technical field of farmland sowing, and particularly relates to a seed leakage monitoring and alarm device for a hole seeder and a seeder. Background Art

[0002] A hole seeder is a common agricultural equipment that sows seeds in holes according to a certain row and hole spacing. It is widely used due to its high sowing quality.

[0003] The current hole seeder has poor control over seed placement accuracy during use. The seeds fall at a high speed during sowing, making it easy to miss seeds, resulting in seed waste and a decrease in yield. The missed seeding areas are difficult to identify and replant. When the machine malfunctions, it is difficult for staff to detect it, resulting in a larger missed seeding area, greater labor intensity for replanting, and very inconvenient operation.
