Description

Technical Field

[0001] The utility model relates to the technical field of wheat breeding, and more specifically to a single-row single-grain seeder for a wheat breeding nursery. Background Art

[0002] Wheat breeding nursery refers to an experimental base dedicated to wheat breeding, usually including wheat breeding experimental fields, breeding laboratories, breeding management centers and other facilities. In wheat breeding experiments, single-row single-seed sowing is performed through a seeder. In the existing wheat sowing, the sowing is carried out by rotating the material-dividing column. However, since the material-dividing column is cylindrical, during its rotation, the wheat seeds between it and the inner wall of the material-guiding channel will be broken due to the friction between the two, affecting the survival rate after sowing. When the wheat seeds are stuck between the two, it will also hinder the rotation of the material-dividing column.

[0003] After searching, a Chinese patent with publication number CN217470726U discloses an automatic sowing device for a wheat seeder, which utilizes the position changes of multiple leak holes on a rotating plate and a fixed plate to achieve the sowing process of wheat seeds, which can reduce the possibility of friction on the wheat seeds, thereby improving the survival rate of the wheat seeds after sowing, and will not hinder the rotation of the wheel.

[0004] When the above patent is in use, when the positions of multiple leakage holes are relative, the wheat seeds can fall smoothly from the guide column and be sown at the same time, and when the positions are staggered, the wheat seeds can be prevented from falling. However, after the wheat seeds fall, it is inconvenient to cover the wheat seeds with soil. It is necessary to cover the seeds with soil uniformly after sowing, and the use effect is poor.
