Plastic film mulching seeder for millet, corn and coarse cereals

Abstract

The invention discloses a plastic film mulching seeder for millet, corn and coarse cereals, which comprises a main chassis (1), an earth leveler (2) is mounted on the front part of the main chassis (1), disk coulter (3) are symmetrically mounted on both sides of the main chassis (1), a land roller (5) is mounted on the main chassis (1) through a land roller axle (4), and a driving sprocket wheel (and an eccentric shaft) (6) is mounted at the end of the land roller axle (4). Through the rotation of the driving sprocket wheel (and the eccentric shaft), a pull rod (pull chain) lever structure is utilized to drive a knocking hammer to knock a soil intake roller, so that soil in the soil intake roller can be smoothly discharged out, and the soil is suitable for seeding in the middle row. The difference of the seeder from similar seeders is that soil is first put on a mulching film and the mulching film is shaped and laid before seeding, consequently, phenomena, such as the dislocation of sprouts from holes and soil hardening on the mulching film, cannot occur, and labor is saved. Pressed by press wheels behind dibbling rollers, concave arcs are formed, so that even a small amount of dew in the morning can flow into holes, consequently, the germination rate and emergence rate of seeds are ensured, the sowed seeds can effectively germinate through soil, and yield is increased.

Description

technical field [0001] The invention relates to the field of agricultural machinery (agricultural tools), in particular to a film-laying seeder for millet, corn, and miscellaneous grains. Background technique [0002] Seeder is a planting machine that takes crop seeds as the sowing object. Seeders used for a certain type or a certain crop are often named after the type of crop, such as grain drills, corn drills, etc. For the sowing of crops, common methods include sowing, drilling and on-demand. Among them, on-demand sowing is also called hole sowing. Since holes are sown at a certain distance on the sowing row, on-demand sowing can not only sow the distance between plants, but also help save seeds. After sowing, in order to maintain air humidity or heat preservation and increase temperature for the seeds, the fields are usually covered with film. For the above-mentioned cultivation steps, the function of the existing sowing device cannot meet the needs of users. After ye...

Problems solved by technology

For the above-mentioned cultivation steps, the function of the existing sowing device cannot meet the needs of users. After years of film sowing, I have discovered the biggest problem, that is, no matter what kind of film sowing equipment, it rains after filming and sowing. The soil is compacted, and the seedlings of millet, corn and other crops cannot be unearthed normally, and the emergence rate is low, which can reach between 30% and 50%. There are often problems such as seedlings running under the plastic film and cannot be unearthed.

The economic benefits brought to users are almost enough, even lost

[0003]In addition, most of the existing farming equipment is large-scale machinery, which is mainly used for sowing large flat areas, and is not suitable for special terrains such as small fields or mountains
