[0025] When in use, the seeder is connected to the agricultural motor vehicle through the connecting end 62. After the connection is completed, the adjustable grain number positioning and falling mechanism 3 is adjusted according to the number of seeds to be sown. In the initial state, the inner material hole 19 and the outer material hole 21 are in a closed state, and single-grain sowing can be carried out without adjustment. When double-grain sowing is required, the inner material hole 19 or the outer material hole 21 can be opened. If the inner material hole 19 is opened, the toggle lever 29 is toggled, and the toggle lever 29 rotates along the inner rotating groove 17, driving the inner driving gear ring 27 to rotate, and the rotation of the inner driving gear ring 27 drives the rotating toothed disc 35 to rotate, and the rotation of the rotating toothed disc 35 drives the rotating teeth 34 to rotate along the fixed toothed disc 26, and the rotation of the rotating teeth 34 drives the rotating plate 36 to rotate, and the rotating plate 36 rotates and rotates in parallel The rotating plate 36 rotates to drive the rotating connecting member 33 to rotate, and the rotating connecting member 33 rotates to drive the telescopic column 44 to move.

After the adjustment is completed, the seeds to be sown are placed in the sowing enclosure 6, and the loosening motor 55 is started. The loosening motor 55 rotates to drive the loosening roller 53 to rotate, and the loosening roller 53 rotates to drive the loosening teeth 54 to rotate. The loosening teeth 54 rotate to loosen the soil, and the grooving teeth 57 dig grooves for the loosened soil.

The drive wheel 48 drives the material control disk 7 to rotate. The material control disk 7 drives the seeds dropped into the material hole 16 to rotate until the seeds rotate to the discharge port 51 and fall into the anti-drift drop tube 52. The seeds fall into the soil dug by the digging teeth 57 through the anti-drift drop tube 52. The setting of the anti-drift drop tube 52 can effectively prevent the seeds from floating and moving due to the influence of the external environment when they fall, resulting in inaccurate sowing position, thereby achieving the technical effect of accurately positioning the seeds for sowing. At the same time, the soil return wheel 60 can bury the seeds after sowing. The above is the specific working process of the present invention. Just repeat this step next time you use it.
