Working principle of the row seeder: When the row seeder is in operation, the movement of the wheels drives the seed metering wheel to rotate. Seeds are dispensed from the seed cups inside the seed box in the required sowing volume into the seed delivery tube, and they fall into the pre-opened furrow via the opener. Then, the soil covering and compaction device covers and presses the seeds into the soil. After germination, the crops emerge in parallel and equidistant rows. Except for adopting different types of seed metering devices and openers, the structure of row seeders for different crops is basically the same. They generally consist of a frame, a traction or suspension device, a seed box, a seed metering device, a transmission system, a seed delivery tube, an opener, a row marker, wheels, and a soil covering and compaction device. Among these, the main factors affecting seeding quality are the seed metering device and the opener. Commonly used seed metering devices include fluted roller, centrifugal, and disc types. Openers include hoe-type, shoe-type, skid-type, single disc, and double disc types.
