[0024] Preferably, the seeding turntable includes a centrifugal wheel disc 2 and a centrifugal rotor 3 installed on the top of the centrifugal wheel disc 2;

[0025] Specifically, the angle compensation mechanism 4 includes a left connecting block 7, a right connecting block 8 and a rotating wheel 5 for being installed on the seed box 1. Preferably, the rotating wheel 5 is installed at the seed outlet of the seed box 1 through a cross-shaped bracket, which not only realizes the connection between the rotating wheel 5 and the seed box 1, but also does not affect the seeds in the seed box 1. The output of the seeds is not affected. A center maintaining block 10 is hinged between the left connecting block 7 and the right connecting block 8. The center maintaining block 10 is hinged to the left connecting block 7 and the right connecting block 8 through a laterally arranged hinge shaft, which is convenient for relative forward and backward rotation with the left connecting block 7 and the right connecting block 8. A vertically arranged slide rod 6 is hinged to the center maintaining block 10, and the slide rod 6 is hinged to the center maintaining block 10 through a longitudinally arranged hinge shaft, which is convenient for relative left and right swinging with the center maintaining block 10. The top of the slide rod 6 is rotatably connected to the rotating wheel 5, which is convenient for the slide rod 6 and the rotating wheel 5 to rotate relative to each other.

[0026] A slide groove engaging block 9 is also slidably mounted on the slide groove rod 6, and a vertical slide groove cooperating with the slide groove engaging block 9 is provided on the slide groove rod 6, so that the slide groove engaging block 9 can slide vertically along the vertical slide groove. A right wheel rotary connector 13 is hinged on the slide groove engaging block 9, and the right wheel rotary connector 13 is hinged with the slide groove engaging block 9 through a horizontally arranged hinge shaft, so that it can rotate relative to the slide groove engaging block 9 forward and backward.
