Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to a precision seeding device for agricultural machinery. Background Art

[0002] Mechanical sowing is an indispensable part of modern agriculture. Using agricultural machinery to accurately sow seeds into the soil greatly improves sowing efficiency and quality.

[0003] In the current existing technology, due to the limited seed germination rate and the lack of crops in some areas, in order to improve land utilization, workers will adopt a secondary replanting method for replanting. With the development of science and technology and the application of artificial intelligence technology in agriculture, automatic laser weeders have appeared in green agriculture. They rely on artificial intelligence algorithms to identify weeds and rely on lasers to emit high-temperature lasers to weed at specific points, greatly reducing the use of pesticides and improving the green and environmental protection of agriculture. However, the use of artificial intelligence in the field of sowing has not yet appeared.

[0004] Existing replanting still requires manual replanting by staff, which is time-consuming and labor-intensive, with high work intensity and labor costs. Therefore, to address the above problems, an agricultural machinery precision seeding device is proposed. Summary of the Invention
