Put a number of cabbage seeds into the seed storage bottle (201), and the seeds are stored on the surface or in the round hole of the seed metering device (202).

[0017] The seeder is started. The driving DC motor (501) is started and the rotation speed is set, and the driving DC motor (501) drives the directional wheel to rotate through the transmission of the synchronous belt drive (502), thereby driving the seeder to move along the ridge of the cabbage to be sown.

[0018] When the seed drill moves forward, it drives the plow (101) to move forward, thereby making a furrow on the ridge where the cabbage is to be sown, and piling soil on both sides of the furrow.

[0019] Sowing. The sowing DC motor (207) is started and the rotation speed is set, and the sowing DC motor (207) drives the seed meter (202) to rotate through the transmission shaft (205); the cabbage seeds falling into the circular holes on the outer periphery of the seed meter (202) pass through the gap between the circular holes and the top of the arc-shaped guide plate of the seed storage bottle (201), and fall into the seeding slideway (204) under the guidance of the arc-shaped guide plate, and then fall into the opened groove.

[0020] Covering the soil. When the seed drill moves forward, it drives the two covering plates (301) to move forward, and the covering plates (301) cover the soil accumulated on both sides of the groove onto the sown cabbage seeds, thereby completing the sowing process of the seeds.

[0021] Continue sowing. Continue the sowing operation of furrowing, sowing and covering the soil. After sowing one row of cabbage, turn off the sowing DC motor (207), hold the handrail, and move the sowing machine to another row through the action of the directional wheel (406) and the universal wheel (409), and continue sowing the next row of cabbage.
