Referring to fig. 2, an auxiliary fan blade 8 is fixedly installed in the middle of a rotating shaft 2, the auxiliary fan blade 8 is located in a suction cavity of a seed discharging structure main body 1, when the distance between corn seeds to be planted is large, the rotating shaft 2 is controlled to rotate at a low speed, the auxiliary fan blade 8 rotates at a low speed along with the rotating shaft 2, the corn seeds slowly rotate along with a seed discharging groove 4 to form a large distance, when the distance between the corn seeds to be planted is reduced, the rotating speed of the rotating shaft 2 is controlled to increase, at the moment, the time for the seed discharging disc 3 to adsorb the corn seeds by rotating at a high speed is short, the required suction force is increased, the auxiliary fan blade 8 fixedly connected in the middle of the rotating shaft 2 rotates rapidly along with the auxiliary fan blade 8, a large internal suction air flow auxiliary adsorbing hole 5 is formed in the inner side of the adsorbing hole 5 to fix the adsorbed corn seeds, and the problem that the corn seeds are not adsorbed stably due to the too fast rotating speed of the seed discharging disc 3 is avoided.

Referring to fig. 3, the front of the reseating baffle 7 is fixedly connected with a seed storage groove 9, the height of the seed storage groove 9 is consistent with the radius of the seed discharging structure main body 1, so that the seed discharging groove 4 which is lower than the circle center can be immersed in the seed stack for sucking and discharging seeds, one side of the seed storage groove 9 is fixedly connected with a seed discharging baffle 10, the length of the top end of the seed discharging baffle 10 from the circle center of the seed discharging disc 3 is smaller than the distance of the inner side of the seed discharging groove 4 from the circle center of the seed discharging disc 3, one side of the seed discharging baffle 10 is fixedly connected with a splash baffle 11, the seed discharging baffle 10 and the splash baffle 11 are parallel, and the two form a seed sowing pipe.

The using method of the invention has the following working principle:

when the corn seed planter is used, the seed storage groove 9 is filled with corn seeds and is communicated with the seed storage groove to ensure that the corn seeds are covered all the time in the using process, the planter is started, when a planting mode with larger distance is needed to be set, the rotating shaft 2 is controlled to be in a low rotating speed state, the seed planting disc 3 rotates until the adsorption holes 5 and the auxiliary suction belts 6 at the seed storage groove 9 adsorb the corn seeds to enter the seed planting groove 4 and rise along with the rotation of the seed planting disc, in the rising process, the seeds on the front side of the outer auxiliary suction belts 6 firstly contact the side surfaces of the auxiliary position baffle plates 7 and are pushed by the gradually widened auxiliary position baffle plates 7, the seeds on the front side of the auxiliary suction belts 6 move inwards along the seed planting groove 4, the seeds right opposite to the front of the adsorption holes 5 are pushed and replaced and stay on the front of the adsorption holes 5, the seeds on the front of the adsorption holes 5 originally slide down along an inclined transition area at the inner side edge of the seed sowing groove 4, so that the corn seeds are always adsorbed at the adsorption holes 5 for seed sowing, the idle sowing rate is reduced, when the corn seeds rotate to the other side along with the seed sowing disc 3, the seed discharging baffle 10 limits the seeds to continue rotating along the seed sowing disc 3 after continuing rotating, and therefore the corn seeds slide out of the seed sowing disc 3 along the arc-shaped groove of the seed sowing groove 4 and fall into the sowing pipe under the limitation of the splash-proof baffle 11 to fall into a hook groove dug by a furrow opener, and then the corn seeds are buried by a covering device to fold soil; when a planting mode with a small distance needs to be set, the rotating shaft 2 is controlled to be in a high rotating speed state, the auxiliary fan blade 8 fixedly connected with the middle of the rotating shaft 2 rotates rapidly along with the auxiliary fan blade 8, and a large internal suction airflow auxiliary suction hole 5 is formed inside the suction hole 5 to fix the adsorbed corn seeds, so that the suction force formed in the suction cavity can still firmly adsorb the corn seeds to perform seed sowing work when the seed sowing plate 3 rotates rapidly; the rotating speed of the rotating shaft 2 is correspondingly adjusted to the required corn sowing distance, so that different planting distances can be obtained, and the free adjustment of the sowing distance of the corn planter is realized.
