The top surface of the seeding sieve 1 is provided with a number of seed screening openings 3, and the areas of the number of seed screening openings 3 are all equal. Fixed shafts 4 are fixedly installed at the four corners of the top surface of the seeding sieve 1. Rotating blocks 5 are sleeved on the outer sides of the four fixed shafts 4. Moving shafts 6 are sleeved on the inner side walls of the four rotating blocks 5. The bottom ends of the four moving shafts 6 penetrate through the top surface of the rotating blocks 5 to connect to a turntable 7. By rotating one of the turntables 7, the moving shaft 6 is driven to rotate and move, so that the rotating block 5 pushes the fixed shaft 4, further driving the seeding sieve 1 to shake, and the seeds inside the seeding sieve 1 are screened out along the seed screening openings 3, pass through the seeding holes 11 of the bottom plate 10 and reach the seeding soil, achieving the function of automatic seeding.

[0019] Refer to Figure 2 , wherein the bottom surfaces of three of the turntables 7 are fixedly installed with rotating shafts 8. The bottom ends of the three rotating shafts 8 are fixedly installed with support columns 9. The bottom surfaces of the four support columns 9 are fixedly installed with a bottom plate 10. Seeding holes 11 are provided on the top surface of the bottom plate 10. The area of the seeding holes 11 is equal to the area of the seed screening openings 3. The seeds are screened out through the seed screening openings 3 and then fall on the ground soil through the seeding holes 11. The areas of the seed screening openings 3 and the seeding holes 11 are equal, which is convenient for seeding.

[0020] Refer to Figure 1 , two limiting rings are sleeved on the outer sides of the moving shafts 6. The two limiting rings are respectively located at the top and bottom of the turntable 7. The limiting rings limit the rotation of the turntable 7 on the outer side of the moving shaft 6, further causing the seeding sieve 1 to shake back and forth, so that the seeds pass through the seed screening openings 3 and contact the soil.

[0021] Refer to Figure 1 , a square hole is provided on one side of one of the support columns 9. A rotating motor 13 is fixedly installed on the top and bottom surfaces of the support column 9.
