Along with the improvement of the operation speed, the seeding opportunity is aggravated by vibration caused by uneven ground surface, seeds discharged by the seed metering device are easy to collide with the pipe wall in the process of being conveyed by the seed guide pipe, so that the original grain spacing is changed, and the consistency of the plant spacing after the operation is poor. The airflow auxiliary seed feeding accelerates the movement of seeds by introducing forward airflow into the seed guide tube, reduces the collision probability of the seeds and tube walls in the seed feeding process, and ensures the consistency of grain distance. Particularly under the high-speed operation condition, the air flow assisted seeding has remarkable advantages. However, the airflow assisted seed feeding can also cause the movement speed of the seeds to be continuously increased in the seed feeding process, and finally the seeds can be projected to the ground surface at a larger speed when being separated from the seed guide tube. Because the initial speed of the seeds when the seeds are separated from the seed guide tube is high, the kinetic energy at the moment of landing cannot be completely released, and then bouncing is generated, and the plant spacing variation is increased after bouncing. The following problems are summarized:
1. as the sowing speed increases, the seeds are bounced and scattered;

3. vibrating the seeding pipe and shifting the grain channel;
4. most of seed pressing wheel bodies are solid, hard in texture, poor in soil adaptability and inconsistent in sowing depth.
