Background

The peanut seeder is a common agricultural machine, and can complete the procedures of ridging, ditching, fertilizing, seeding, earthing, pressing, laminating and the like at one time. The peanut seeder consists of a ridging mechanism, a fertilizing mechanism, a seeding mechanism, an earthing and compacting mechanism, a pesticide spraying device, a film covering mechanism and a punching mechanism (or two times of manual punching); at present, common peanut seeder is mostly ridging tectorial membrane seeder and ridging tectorial membrane seeder that punches, the benefit of peanut ridging tectorial membrane seeding: firstly, the soil moisture is preserved and extracted, and the seeds can be sowed and harvested in advance 7 days; and secondly, the ridging planting of the peanuts provides a soft seedbed for the growth process of the peanuts, so that the root systems of the peanuts are easy to prick, and the yield of the peanuts is improved. The prior art has the following problems: 1. ridging and film mulching seeder; the process comprises ridging, sowing and film covering; after the peanut seedlings emerge, the mulching film of the peanut needs to be punched manually (or with the help of a special tool) to assist the film breaking growth of the peanut seedlings, and if the punching and the film breaking are not timely, the phenomenon that the peanut seedlings are burnt due to overhigh temperature under the film is easily caused, thereby influencing the peanut yield. 2. Ridging, film covering, punching and seeding machines; compared with ridging film-covering seeders, the ridging film-covering seeder omits a punching operation link, but the wind is strong in spring, the mulching film is easily torn by wind along the punching holes of the mulching film or the mulching film with large area is lifted, so that the effects of heat preservation, soil moisture lifting and advanced planting cannot be achieved. 3. The two types of machines operate in drought and rainless in spring, and the yield of peanuts is reduced due to the influence on the emergence rate of the peanuts caused by poor soil moisture content; or the late-stage reseeding increases the labor cost.
