[0002] In the field of peanut planting, the traditional method of peanut sowing is to manually create ridges and dig holes with tools such as iron milling machines, and then drop seeds along the ridges. This is inefficient, time-consuming and inconvenient. However, with the rapid development of agricultural mechanization, the sowing method is gradually developing from traditional manual sowing to mechanized sowing.

[0003] Since peanuts are one of the crops with a relatively large planting density, it is necessary to control the sowing spacing, such as row spacing and plant spacing, relatively reasonably during sowing to ensure stable growth of peanuts in the later stage. The existing seeders can be used to sow single-row, double-row or multi-row peanuts, but the discharge mechanisms of the existing peanut seeders are generally fixed, and the spacings between adjacent discharge mechanisms are equal, which makes it difficult to adjust the spacing as required, and thus it is inconvenient to adjust the row spacing of peanut sowing. For this reason, the utility model newly proposes a seeder that is easy to adjust the sowing spacing, which can adjust the row spacing and spacing of peanut sowing, and is better to use.
