After the driving teeth rotate upward, the first rotating block 515e and the second rotating block 515b are reset and knocked under the action of the reset spring 515f, and the debris blocking the inner walls of the first seed blocking half tube and the second seed blocking half tube are vibrated and fall down to avoid seed blocking. At the same time, the power shaft 515k drives the active part 515m to rotate, and the active part 515m drives the driven part 515c to rotate, so that the driven part 515c drives the seed discharge sleeve 515l to move downward, so as to avoid the random scattering of seeds when clearing the blockage and improve the accuracy of seed placement.
