Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1-8, the utility model provides a peanut seeder distance seed metering device, include: the peanut seeder comprises a seed storage box 3 and a seeding mechanism, wherein the seed storage box 3 is fixedly arranged on a bottom plate 1 of the peanut seeder, the bottom end of the seed storage box 3 penetrates through the bottom plate 1 of the peanut seeder and is arranged between two rows of wheels 2 of the peanut seeder, a mounting seat 4 is fixedly arranged at one end of the bottom plate 1 of the peanut seeder, and a seed outlet hole is formed in the bottom end of the seed storage box 3;
