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.

In plants case, the seed into plants case is divided into 3 under spacer function and fills kind of a region, and power is transmitted to drive sprocket, in drive chain
Under the induced effect of wheel, combined type, which fills kind of a wheel and rotate, fills kind.When combined type fills kind wheel after overcharging kind of area and completing to fill kind, into
Enter flexible synchronous shield kind band shield kind region；At this point, shield kind band drive sprocket rotates synchronously under the action of power with Chong Zhong mechanisms,
Shield kind of band with to fill kind of a speed of related movement for wheel be zero, advantageously reduce seed damage.Then, seed moves to bottom with type hole
When at ejector blade, the seed that combined type corresponding with seed-dropping plate fills on kind of wheel monomer is double in the effect of star ejector blade and gravity
Recast is pushed out under, is fallen into planting pipe from planting mouth, is realized seeding.And not corresponding with planting mouth on seed-dropping plate fill kind of a monomer
Seed in type hole is not discharged, and is entered under the effect of the shield kind of seed-dropping plate and filled kind next time, and realization is secondary to fill kind, reduces
Hole rate, when next cycle seed movement is to when filling kind of actuator base, seed-dropping plate is moved back and forth in the presence of cylinder to falling
Planting mouth is correspondings with another kind of monomer that fills on kind of plate, monomer progress seeding, another two combined type fill kind of monomer into secondary or
Kind is filled three times, repeatedly, is formed and is repeated to fill kind, realized simple grain precision metering device, reduce hole rate, meet and clear kind is wanted
The characteristics of not rounded seed simple grain mechanization asked is charged seed.
The present invention fills kind of principle using repetition and fills kind of a structure using combined machine formula, passes through and controls to adjust the reciprocal of seed-dropping plate
It moves and mechanically fills kind of a respective outer side edges, realize controllable simple grain precision metering device, and dropped under the action of flexible synchronous protects kind band
Low seed damage, star Tui Zhong mechanisms can force clear kind, and the sowing that various crop is can be applied to by the design of different type holes is made
Industry has the characteristics that simple grain rate is high, seed damage is small, simple in structure, easy to use, stability and high efficiency, adaptable.
