Description

Technical Field

[0001] The utility model relates to the technical field of seeding equipment, in particular to a seeding machine. Background Technique

[0002] For the planting of traditional green vegetables such as rapeseed and Chinese cabbage, the sowing or dibbling method is generally adopted. When using the sowing method, first scatter the seeds in wet soil. After the green vegetables grow to a certain extent, due to the high planting density of the green vegetables, a part of the green vegetables need to be removed, which will cause a certain loss of seeds. The removed green vegetables can also be transplanted, which will increase the workload. When using the dibbling method, it is necessary to dig pits at a certain interval first, and then sow two or three seeds in each pit, with a large workload. Since the seeds of green vegetables are relatively small, the existing hill-drop planters often cannot be directly applied to the planting of green vegetables. The utility model patent with the publication number of CN219269529U discloses a green vegetable seeding machine. Although it can reduce the phenomenon of empty sowing holes, it relies on the self-gravity of the seeds to make the seeds fall into the soil. The seeds falling on the soil surface are blown by the external wind, and there is a problem that the seeds are blown by the wind, resulting in a change in the plant spacing and it is difficult to ensure a stable plant spacing.
