Description
Technical Field
The utility model belongs to agricultural machinery, in particular to a seeder, which is a universal seed sowing device of an electronic suction-blowing multi-row multifunctional seeder.
Background
Seeders have been widely used as agricultural machines, and prior art precision seeders include air-suction type seed sowing devices and air-blowing type seed sowing devices.
The air-suction seed sowing device has the advantages of low seed feeding point, flat seed bed, uniform seed distribution and consistent seed depth, and when the air-suction seed sowing device works, a high-speed fan generates negative pressure and transmits the negative pressure to a vacuum chamber of a seed sowing monomer. When the seed plate rotates, the seeds are adsorbed under the negative pressure of the vacuum chamber and rotate along with the seed plate. When the seeds are rotated out of the vacuum chamber, they are no longer under negative pressure and fall into the groove by their own weight or under the action of the seed scraper.
The air-blowing type seed sowing device fills seeds into the molding holes by means of the self weight of the seeds and the auxiliary force of air flow, and blows off redundant seeds by utilizing the air flow ejected by the air nozzle, so that the single-seed precision sowing is realized, the seeds are saved, and the seedlings are uniform and strong; when the single-seed sowing device works, the holes of the seed sowing device are filled with seeds in the seed filling area, redundant seeds are blown out by high-pressure airflow when the seeds pass through the lower part of the air nozzle, only one seed at the bottom of the hole is left and then enters the seed protecting area, the seed pushing piece generally needs to be extended into the seed pushing groove of the seed sowing plate to forcibly push the seeds in the holes in the binding section of the seed protecting area, and finally the seeds fall from the seed sowing port to realize single-seed sowing.
The air-suction seed metering device can only discharge single-row seeds, and for a seeding machine for multi-row seeding, one seed metering device is required to be arranged in each row, so that the manufacturing cost of the seeding machine is undoubtedly increased, and the manufacturing cost of the seeding machine is improved; the air-blowing seed sowing device can discharge a plurality of rows of seeds but cannot adsorb the seeds; in addition, no matter the air-suction type seed sowing device or the air-blowing type seed sowing device is adopted, the type holes for accommodating seeds are fixed, and only the seeds with similar particle sizes and shapes can be accommodated, so that when crops with different particle sizes and shapes are sowed, an applicable seeder needs to be replaced, the manufacturing cost of the seeder is increased, and the manufacturing cost of the seeder is increased; meanwhile, after the seeds leave the seed discharging disc and enter the seed discharging pipe, the seeds fall down from the seed discharging port under the action of the seed scraping device or the pushing force of seed discharging and seed pushing by the dead weight of the seeds, so that single-seed sowing is realized. The seeds fall from the seeding port by the self weight, the advancing speed of the seeder is limited by the time required by the free falling body of the seeds, and once the planting distance is determined, the operation efficiency cannot be improved; the seed falls from the seed metering opening under the action of the seed scraper or the pushing force of the seed metering push piece, and the seed scraper or the seed metering push piece is directly contacted with the seeds, so that the surface of the seeds is easily damaged or the seeds are broken to influence the germination of the seeds. So far, no practical application and literature report of the general seed metering device of the electronic suction-blowing type seeder is found.
