Description
Technical field
The utility model is related to technical field of seeders, specifically a kind of wheeled air-suction seed metering device.
Background technology
Seeder take crop seed as the planting machinery for sowing object.For certain class or the seeder of certain crop, Chang Guan
With crop species title, such as grain dill, corn seeding drill, cotton planter, herbage seed broadcaster.It is right that seeder is planted
As if the seed of crop or it is made the capsuled seed of pill shape.It by seeding method can be divided into vacuum seed sowing machine seed broadcaster,
Drill for sowing in lines and the class of hill-drop drill 3.Start all types of precision drills of a large amount of development the fifties, can precise control application rate, cave
(strain) away from and seed level.Start the strength seeding precision drill of development, its feed mechanism for seed (aspirated-air type, vapour-pressure type or air-blowing the seventies
Formula) a row seed is discharged in certain intervals using malleation or negative-pressure air-flow, simple grain precision hill-drop sowing is realized, it is mechanical with traditional
Feed mechanism for seed is compared, with the amount of broadcasting it is accurate, injuring-free seed is sub- the features such as.In addition with a kind of mechanical accurate seeding apparatus.It is band fertilising
The row row-crop drill of suspension type 6 of device, can be used for the drilling and bunch planting of the imtertilled crops such as soybean, corn and sorghum.
At present using it is most be aspiration type sowing device, aspiration type sowing device produces negative pressure when working by high-speed fan, passes
To the vacuum chamber of seeding monomer.When discharge plate is turned round, the absorbed seed under vacuum chamber suction function, and turn with discharge plate
It is dynamic.After seed produces vacuum chamber, negative pressure is not subjected to, just fallen in ditch by deadweight or in seed scraping device effect.Aspirated-air type is broadcast
Planting device major influence factors has construction and the adjustment of vacuum, sucker shape, seed sizes and seed scraping device.
Existing aspiration type sowing device poor sealing, easily misses seed, causes to waste；Resistance is larger during operation, wave
Take the energy.Seeding is not accurate enough, influences percentage of seedgermination.
