High-efficiency and precision seeding plays a very important role in promoting agricultural production. Wheat is a general term for wheat plants. It is a monocotyledonous plant and a grass plant widely planted around the world. Wheat caryopsis is one of the staple foods of humans. It can be ground into flour to make bread, steamed buns, biscuits, noodles and other foods; after fermentation, it can be made into beer, alcohol and liquor, or biofuel.

[0003] Wheat is sown by a sowing device installed on a wheat seeder. When the existing wheat sowing device is in use, it needs to turn and adjust the vehicle's forward direction when the machine drags the sowing equipment to one end of the field. During this process, the seeder is still performing sowing operations, which results in denser wheat sowing in the inner circle of the turning path, while sparser wheat sowing outside the turning radius, affecting the sowing quality.
