The present invention discloses a precision seeding
machine, which comprises a rack
assembly, a seeding box, a seeding
monomer rack, a round disc ditching device, a sliding cutter ditching device, a soil covering device and a pressing depth limiting wheel, wherein the seeding
monomer rack is connected to the rack
assembly, the seeding box is arranged on the seeding
monomer rack, the round disc ditching device, the sliding cutter ditching device, the soil covering device and the pressing depth limiting wheel are sequentially arranged on the seeding monomer rack from front to rear, a seeding mechanism is arranged in the seeding box, an opening-closing device is arranged between the material discharging port of the bottom portion of the seeding box and the seeding mechanism, the seeding mechanism comprises a seeding
pipe, a seeding wheel and a seeding groove, the seeding wheel is arranged in the seeding
pipe, the seeing wheel is provided with at least one seeding groove, and the seeding wheel is connected to the round disc ditching device through a
drive shaft. According to the present invention, the precision seeding
machine has characteristics of simple structure and convenient operation; the seeding is performed with the seeding mechanism, such that the production cost is reduced, the ditching depth is stable, the seed can tightly contact the soil on the bottom of the
ditch, and the precision seeding
machine is suitable for the basic situation of the vast rural areas of our country, and has advantages of time saving, labor saving, and working efficiency improving.
