Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to an automatic seedling raising and seeding bed soil box structure. Background Art

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a particular type of crop are often named after the crop, such as grain drills, corn drills, cotton drills, and grass spreaders. After sowing, the seeding area needs to be covered with a layer of soil. The soil in the soil box is usually freshly extracted, but this soil often clumps. To ensure a more even covering, a crushing wheel is added to the soil box to break up the clumps.

[0003] When breaking up the agglomerated soil, the existing soil box can usually only break up the soil once. Regardless of whether the broken up soil meets the standards or not, it will be mixed together and sprinkled on the sowing position, making the soil covering uneven. Utility Model Content
