[0002] The country prioritizes food security, and subsidies for agricultural machinery continue to increase, driving significant growth in the overall seed drill market. Rising labor costs, coupled with the shift to contiguous planting and the influx of migrant workers into urban areas, have reduced the number of people engaged in agricultural production, with an aging population and a growing reliance on agricultural mechanization. The continued high sales of low-end seed drills has stagnated grain production, while also leading to significant homogeneity and a significant waste of power and labor.

[0003] Land in much of the Central Plains is relatively concentrated, with good land transfer conditions, making it suitable for the promotion of mid- to high-end, high-speed, precision seeders. Large-scale growers and cooperatives are numerous, and their mindsets are gradually shifting. Some forward-thinking growers and cooperatives have advanced agronomic practices and recognize the increased efficiency of high-end equipment.

[0004] Low-end products are inexpensive and easily accepted by ordinary users. They have a service life of about 2-3 years. The service life of components such as furrow openers and seeders is short, the sowing depth control is lower than that of high-end precision seeders, and the operating speed and efficiency are low.

[0005] At present, the seed drills in the existing technology usually use the ground wheel to transmit the power to the gearbox through the "big wheel with small wheel", and then adjust the speed ratio in the gearbox to achieve different plant spacings; at the same time, it is impossible to sow multiple crops with one machine, that is, it is impossible to achieve different rows with different plant spacings and different crops.
