[0006] Preferably, each of the control cores includes a fixed cylinder, and one end of the fixed cylinder is fixedly connected to the isolation disk, the inclined disk is fixedly arranged at an end of the fixed cylinder away from the isolation disk, the inclined disk has a wavy structure on the side facing the isolation disk, and the distance between the bottom of the inclined disk and the isolation disk is smaller than the distance between the top and the isolation disk; the side of the inclined disk corresponding to the isolation disk is covered with a second stainless steel slip ring, and the paddle at the end of the finger clamp is against the surface of the second stainless steel slip ring.

[0007] The beneficial effects of the utility model are as follows: one end of the main shaft is connected to the driving device through a coupling, so as to obtain power to synchronously drive each seed clamping disk and each seed guide disk. When sowing seeds, the seeds fall into the bottom of the corresponding seed clamping disk from each feed port. Each rotating seed clamping disk picks up the seeds through the finger clamp and squeezes them in the direction of the corresponding seed guide chamber until they meet their respective seed throwing ports.

[0018] In the above structure, one end of the main shaft 3 is connected to the driving device through a coupling, so as to obtain power to synchronously drive each seed clamping disc 9 and each seed guide disc 4. When sowing seeds, seeds fall into the bottom of the corresponding seed clamping disc 9 from each feed port 15. Each rotating seed clamping disc 9 picks up the seeds through the finger clamp 10 and squeezes them toward the corresponding seed guide chamber 2 until they meet their respective seed throwing ports 8. The seeds are then ejected into the corresponding seed guide groove 5. During the rotation of the seed guide disc 4, the seeds fall out from their respective sowing ports 6. Since the two sowing ports are very close, sowing work with a small spacing is achieved.

[0020] The isolation disk 7 and the first stainless steel slip ring 16 in this setting are metal insert injection molding structures. The first stainless steel slip ring 16 not only reduces the rotation resistance of the seed clamping disk 9, but also effectively avoids the wear of seeds, thereby avoiding the problem of seed damage, and greatly improves the service life of equipment components. The seed clamping disk 9 is similar to the existing structure, and the control core 11 controls the opening and closing angle of the finger clamp 10 through the second stainless steel slip ring 18, thereby reducing the rotation resistance of the seed clamping disk 9, reducing wear and extending the service life.
