Fine seeding machine for peanut field breeding

The invention discloses a peanut field breeding precision seeder which comprises a rack, a driving land wheel device and a seeding device, the seeding device comprises a seed pre-filling device, an air suction seed discharging device, an air suction seed cleaning device, a seeding adjusting device and the like, and seeds are controlled by the seed pre-filling device to enter the air suction seed discharging device according to requirements; residual seeds are collected by combining the air-suction seed cleaning device, and the seeding adjusting device can automatically adjust the seeding speed and the distance between a scraper and a seeding port according to the peanut seeding speed, so that the damage rate of peanut seeds is reduced, and the optimal seed filling performance is realized; the overall shape of the driving land wheel device is V-shaped, and the driving land wheel device has a relatively low slip rate, so that the seeding stability of the seeding device of the peanut seeding machine and the accu
