Seeding machine capable of adjusting seeding rate of small-particle seeds and use method of seeding machine

The invention discloses a seeding machine capable of adjusting the seeding rate of small-particle seeds and a use method thereof, and relates to the field of agricultural mechanical devices, the seeding machine capable of adjusting the seeding rate of small-particle seeds comprises a seeding machine body, a fixed seeding box is arranged on the side surface of the seeding machine body, and a fixed motor is arranged on the inner side of the seeding machine body; through cooperative use of a driving belt wheel and a fixed belt, a second rotating part and a first rotating part are conveniently driven to respectively rotate for use, so that the purposes of turning over the ground and turning over sown seeds are achieved, and the problems that the ground is too hard, so that a worker cannot rapidly sow and use the seeds, and the sowing time is shortened during sowing are avoided. The seeds are accumulated, the number is too large during sowing, and the subsequent germination condition is affected, through cooperati
