[0025] Preferably, the seeding mechanism has an accommodating cavity 9 inside, and a sowing silo 10 is provided inside the accommodating cavity 9. The sowing silo 10 is installed concentrically with the bearing cover I4. A small cover 11 is provided on the sowing silo 10, and a seeder I12 and a seeder II13 are provided inside the small cover 11.

[0026] Preferably, twelve duckbill-type hole-opening mechanisms are evenly spaced on the outer edge of the seed-seeding mechanism, and the duckbill-type hole-opening mechanism includes a fixed duckbill flap 14, a movable duckbill flap 15, a duckbill mounting plate 16, a hole turning rod 17, a return spring 18, and a duckbill shield 21. The fixed duckbill flap 14 is fixedly connected to the duckbill mounting plate 16, and the duckbill shield 21 is located at the outer edge of the middle part of the fixed duckbill flap 14 and the duckbill mounting plate 16.

[0027] Preferably, the interior of the duckbill mounting plate 16 is socket-shaped, the socket-shaped inner cavity of the duckbill mounting plate 16 is communicated with the accommodating cavity 9 , and the inner cavity of the duckbill mounting plate 16 is adjacent to the sowing silo 10 .

[0028] Preferably, the movable duckbill flap 15 is installed concentrically with the hole turning rod 17, the hole turning rod 17 is installed concentrically with the return spring 18, and twelve duckbill partition plates 19 are connected at equal intervals between the twelve duckbill hole opening mechanisms.

[0029] Preferably, the fixed duckbill flap 14 and the movable duckbill flap 15 are buckled together to form a seeding opening.

[0030] Preferably, the hole turning rod 17 is provided to pass through the center of the return spring 18 .

[0031] The working principle of this utility model patent is:

[0032] Before the seeding mechanism works, the seeds are manually introduced into the material box, and the seeds enter the internal accommodating cavity 9 through the upper seeding port of the seeding mechanism by relying on their own weight and the squeezing force between the seeds; when the seeding mechanism works, the accommodating cavity 9 rotates relative to the seed group, and the seeds of the seed group close to the eye-shaped duckbill mounting plate 16 at the bottom of the accommodating cavity 9 enter the eye-shaped duckbill mounting plate 16 and the pre-filling space (the space between two adjacent eye-shaped duckbill mounting plates 16) in a limited manner under the stirring action of their own weight and the rotation of the accommodating cavity 9, completing the seed filling process; as the accommodating cavity 9 rotates, the seeds of the seed group close to the eye-shaped duckbill mounting plate 16 at the bottom of the accommodating cavity 9 enter the eye-shaped duckbill mounting plate 16 and the pre-filling space (the space between two adjacent eye-shaped duckbill mounting plates 16) in a limited manner, completing the seed filling process; As the seed tray rotates, the seeds carried in the eye-shaped duckbill mounting plate 16 and the pre-filled space leave the seed group along with the accommodating cavity 9 and enter the seed clearing area. In this area, due to the change in the force on the seeds, the seeds in the pre-filled space slide down to the seed storage chamber under the action of gravity, leaving only one seed in the eye; as the seed tray continues to rotate, the eye-shaped duckbill mounting plate 16 enters the seed protection area, and the seeds gradually enter the two adjacent pre-filled spaces from the eye-shaped duckbill mounting plate 16, and the seeds are transported to the seeding port (between the fixed duckbill flap 14 and the movable duckbill flap 15). When the duckbill type hole-opening mechanism penetrates into the soil, the spring 18 drives the hole turning rod 17 to swing, and the movable duckbill flap 15 opens in the soil to form a hole. The seeds at the seeding port enter the hole formed in the soil through the gap opened by the fixed duckbill flap 14 and the movable duckbill flap 15, completing the seeding process. Each time the duckbill type burrowing mechanism is inserted into the soil, it completes a similar seeding motion with the fixed duckbill flap 14 and the movable duckbill flap 15 vertical to the ground.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
