Description

Formula single-grain precision seeding apparatus is filled in combination again
Technical field
The present invention relates to a kind of combinations to fill formula single-grain precision seeding apparatus again, especially for not rounded seed in agricultural machinery Single-seed spacing unit belongs to agricultural machinery precise sowing technical field.
Background technology
Precise sowing technology is that the seed of quantification is multicast to the soil of determining depth according to determining line-spacing, grain square In, i.e., application rate is accurate, plant/line spacing is accurate and seed level is accurate.Precise sowing can be single grain fine sowing, can also be more One cave, but need to meet that every seed number per is identical ensures the accurate of application rate and spacing in the rows.Precise sowing technology is by advising plant growth Rule is developed with characteristic, therefore can guarantee the equiblibrium mass distribution of field seed, makes the conditions of growth and development such as the water, fertilizer, light of seed Reach best, to be a kind of abridged edition increasing that can significantly improve crop yield and quality with the advantages such as strong sprout, time saving, laborsaving The engineering technology of effect.With agrotechnical development, especially genetic breeding, agronomic culture, seed working process etc. in recent years The fast development of technology provides more reliable guarantee for precise sowing technology, and precise sowing technology is made at home and abroad to obtain large area Popularization and application, while single grain fine sowing also becomes research hotspot in recent years.Currently, most field crops are via traditional Drilling, bunch planting, semi-accuracy seeding gradually develop to precise sowing mode, and crop species are also by similar rounds such as corn and soybean, beets Seed gradually develops to the direction of the irregular crop seed such as rice, vegetables, wheat.Studies have shown that using precise sowing technology Yield compared to traditional seeding technique yield amplification be 10%~30%, precise sowing technology is more advanced, and effect of increasing production is brighter It is aobvious, and single grain fine sowing is a kind of new cultivation technique put forward on the basis of precise sowing, can be made for more grain Precision Seeding It is more evenly distributed in field, reduces shading, is conducive to make full use of photosynthesis, section kind obvious effect of increasing production.Therefore, simple grain Precision Seeding technology has become the main direction of development of modern precision seeding technique.
Precision metering device technology is one of the technology of precise sowing most critical, and realizing precision metering device then needs to lean on precision metering device Device.In recent years to the research of precision seeder primarily directed to the non-circular seed such as corn and soybean, peanut, wheat, rice, although The precision metering device technology of these crops has been achieved for significantly improving at present, but since these shapes of the seed are irregular Reason, it is still the difficult point of single grain fine sowing technology that seed-filling rate is low.As the development of agricultural modernization and single grain fine sowing high yield are planted The continuous popularization and application of training technology, urgent need develop a kind of single-grain precision seeding apparatus suitable for non-circular seeds having abnormal, The agricultural machinery for developing simple grain precise sowing is inexorable trend.It is produced into promote simple grain precise sowing technology with reducing Originally, increase yield, it is urgently to solve now that research and design, which goes out stable, simple in structure, the adaptable single-grain precision seeding apparatus of performance, Certainly the problem of, to improving productivity effect, reducing cost, the development for accelerating modernization mechanized cultivation has realistic meaning.
