Description
Technical field
This utility model belongs to agricultural mechanical field, relates to the feed mechanism for seed of seeder, concentrates feed mechanism for seed more particularly to a kind of seeder.
Background technology
In mechanization of agriculture produces, seeder is with crop seed for sowing the planting machinery of object, for certain class or the seeder of certain crop, such as grain dill, corn seeding drill, cotton planter, herbage seed broadcaster etc., seeder each sowing unit needs feed mechanism for seed is separately configured and plants case, seed in seed-box can be dredged uniformly seed flow or sow with continuous print single seed by feed mechanism for seed, stable to control application rate, it is achieved uniformly to sow.
Common have strip sowing seed discharge device, a hill-drop feed run, currently used more for mechanical seed sowing device.During drill for sowing in lines operation, road wheel driving seed wheel to rotate, seed seed cup in seed-box application rate on request enters seed spout, and in plough falls into the groove held successfully, then by earthing compacting device, seed is covered compacting.For the drill for sowing in lines of Different Crop in addition to using different types of feed mechanism for seed and plough, its structure is essentially identical；Hill-drop drill by a line spacing and cave away from, seed cavitation is sowed.1 or several seeds, single grain fine sowing or many bunch plantings can be broadcast in every cave, is mainly used in the imtertilled crops such as Semen Maydis, Cotton Gossypii, Radix Betae, Helianthi, beans, it is possible to make row-crop drill；External common use aspiration type sowing device, is produced negative pressure by high-speed fan during work, passes to the vacuum chamber of seeding monomer.During discharge plate revolution, absorbed seed under vacuum chamber suction function, and rotate with discharge plate.After seed produces vacuum chamber, it is not subjected to negative pressure, just by conducting oneself with dignity or falling in ditch in seed scraping device effect.
There are some drawbacks in reality is sowed, first, seeder uses each sowing unit feed mechanism for seed is separately configured and plants case, and each sowing unit is due to feed mechanism for seed and the restriction of kind case size, the spacing of two sowing unit is bigger, it is impossible to meets some crops and requires the agriculture requirement of little line-spacing；Secondly, planting with sowing machine different crops, when being adjusted seeder, each sowing unit needs to adjust one by one, affects efficiency；Again, seeder each sowing unit correspond to feed mechanism for seed is separately configured and plants case, and structure is complicated, and trouble point is many.Thus, the feed mechanism for seed area research of seeder being improved raising sowing efficiency, reducing equipment fault is current urgent problem.
Summary of the invention
This utility model purpose is just to provide a kind of seeder and concentrates feed mechanism for seed, by the corresponding concentration feed mechanism for seed of seeder kind case, the corresponding multiple sowing unit of concentration feed mechanism for seed, simultaneously to each sowing unit conveying seed, sowing different crops is easy to use, improves work efficiency.
The technical solution adopted in the utility model: feed mechanism for seed concentrated by a kind of seeder, including frame, the kind case being packed in frame, described kind of case inner bottom part is provided with air main, described air main is connected with blower fan, described air main picks out a tilting averaging wind pipe of row respectively, arranges concentration feed mechanism for seed, install homogenating plate between described air main and concentration feed mechanism for seed in described frame；
