Seed feeding device for precision seeding of seeding machine

The utility model provides a seed feeding device for precision seeding of a seeder, which comprises a feeding funnel and a connecting pipe, partition plates are symmetrically and slidably arranged at the upper end of the connecting pipe, a synchronous moving component is arranged between the partition plates and the connecting pipe, and discharging plates are symmetrically and rotatably arranged on the connecting pipe at the lower ends of the partition plates. The synchronous rotating assembly is arranged between the discharging plate and the partition plate, through the arranged partition plate and the synchronous moving assembly, the partition plate can synchronously move towards the two sides, so that synchronous opening and closing of the partition plate are achieved, and then periodic discharging of the feeding hopper to the discharging plate is achieved; and meanwhile, the seeds discharged from the partition plate can be temporarily stored through the arrangement of a discharging plate, and the discharg
