As shown in Figure 3 and Figure 4, described suction-chamber's housing 9 is by suction-chamber's base 20, suction muffler 16, air blowing chamber 18, adapter cavity 19
Constitute with dividing plate 17, suction-chamber's base 20 is arranged on offer fixed position on seeder for Fig. 1 and Fig. 2 of the present invention, in Fig. 1 and Fig. 2
Air intake duct 2 communicate with suction muffler 16, provide lasting negative-pressure air-flow for suction muffler 16, its be used for seed is adsorbed in circumferentially
In the sucker 28 of arrangement, suction muffler 16 region θ=220～280 ° of the present invention；Gas blow pipe 6 in Fig. 1 and Fig. 2 and air blowing chamber 18 phase
Logical, provide lasting malleation air-flow for air blowing chamber 18, it is used for the seed on discharge plate 10 is blown in grain conductor 7, the present invention
Air blowing chamber 18 region ρ=30～50 °；The transitional region that described adapter cavity 19 and discharge plate 10 form more sealing can effectively prevent
Negative-pressure air-flow and malleation air-flow mutually throw the air pressure wild effect that gas brings, adapter cavity 19 region σ=30～110 ° of the present invention.
As shown in Figure 5 and Figure 6, described seed sowing shell 8 by seeding shell body 21, fill kind of mouth 23, seed feeding chamber 24, unload kind of mouth 25
Mouth 22 forms with charging seed, and seeding shell body 21 inner side is coupled by bolt 5 with suction-chamber's housing 9, in seeding shell body 21 outside peace
Dress kind case 1, grain conductor 7 is connected at mouth 22 of charging seed, and unloads kind of a sieve 3 and is threaded connection with unloading kind of mouth 25.
As shown in Figure 7 and Figure 8, described discharge plate 10 is made up of discharge plate body 26, chute 27 and sucker 28.Described chute
27 is that discharge plate body 26 removes material area, and sucker 28 is opened in chute 27 central authorities, and sucker 28 provides in suction muffler 16 and continues
Realize in the presence of negative-pressure air-flow inhaling planting, concentric circles annular groove 27 has agitation, separates to the population in seed feeding chamber 24, is easy to
Sucker 28 absorbed seed, it is combined with sucker 28 is to realize inhaling at a high speed the important means planted；When the sucker 28 of absorbed seed is migrated
When leaving seed feeding chamber 24, concentric circular type chute 27 has attaching and effect of contraction to the seed being adsorbed at sucker 28, its with
Sucker 28 combination is the Important Action preventing from charging seed in advance under vibrating conditions, simultaneously for meeting agriculture requirement and reaching preferably
Seeding effect, air blowing chamber 18 provides lasting malleation air-flow, by sucker 28, seed is blown into grain conductor 7, realizes the company of seed
Continuous, fixed point is charged seed.For guaranteeing that chute 27 plays agitation, centrifugation, chute 27 aperture B to the population in seed feeding chamber 24cYing great
In single seed average grain diameter daAnd the average grain diameter less than two seeds, i.e. da＜ Bc＜ 2da；Sliding in migration process for guaranteeing
Groove 27 has support and effect of contraction to the seed being adsorbed at sucker 28, considers that seed is smoothly launched at sucker 28 simultaneously,
Chute 27 depth hcShould be less than single seed average grain diameter daAnd it is more than single seed average grain diameter da1/4 times, i.e. da/ 4 ＜ hc
＜ da；For guaranteeing that seed is adsorbed in sucker 28 and prevents seed jam sucker, hole sucting diameter dkShould be less than single seed average grain diameter
daAnd it is more than single seed average grain diameter da1/5 times, i.e. da/ 5 ＜ dk＜ da.
The course of work of the present invention is：
Seed in kind of case 1 flows in the seed feeding chamber 24 of seed sowing shell 8 via filling kind of mouth 23 under gravity, power source
Drive drive sprocket 12 and drive feed shaft 11 and discharge plate 10 to turn round, on discharge plate 10, concentric circles annular groove 27 is to seed feeding chamber
Population in 24 carries out stirring, separates, and improves population mobility in seed feeding chamber 24, via air intake duct 2, suction muffler 16 in sucker 28
Seed is adsorbed in sucker 28 by the volume inspiratory flow that place produces, and adsorbed seed rotates with sucker 28, when absorbed seed
When sucker 28 is rotated away from seed feeding chamber 24 with discharge plate 10, concentric circles annular groove 27 has support to the seed of absorption at sucker 28
Echo effect of contraction, can the phenomenon of charging seed in advance brought of effectively solving unit vibration, leave air-breathing when taking seed-bearing sucker 28
When chamber 16 region alpha enters blow pressure chamber 18 region beta, negative-pressure air-flow is cut off by dividing plate 17, now the seed in sucker 28 gravity, from
Mental and physical efforts and acting on via sucker 28 under the collective effects such as the malleation air-flow on seed, launch and via mouth of charging seed at sucker 28
22 enter grain conductor 7 and then discharge, and complete seeding process.After the completion of operation, outward winding and unload kind of a sieve 3, plant surplus in case 1 and seed feeding chamber 24
Remaining seed can draw off from unloading kind of mouth 25 simultaneously.
