As depicted in figs. 1 and 2, the curved projection of the centre bore of end cap 1 is provided around on end cap 1（The shape of a hoof）Gas
Suction-chamber 6, end cap 1 is divided into air-suction chamber 6 part（The suction kind room 9 of corresponding housing 3）With non-air-suction chamber 6 part（The falling of corresponding housing 3
Plant area 10）, this air-suction chamber 6 is provided with negative pressure line 7 in end cap 1 outer wall, close in the inner side of end cap 1 and the side card of discharge plate 2
Envelope cooperation.
As shown in Fig. 2 ~ Fig. 3, discharge plate 2 be evenly distributed with suction hole 8 card ring week and the edge of discharge plate 2 is provided with wheel
Tooth, the output shaft of direct current generator 4 is fixed with driving gear 15, and discharge plate 2 is meshed with driving gear 15 by the gear teeth.
As shown in figure 4, housing 3 inner space is divided into suction kind room 9 and fall-sowing area by the demarcation strip being provided with arc in housing 3
10, formation suction plants room 9 space, in housing 3 to inhale that kind of room 9 is corresponding with air-suction chamber 6 position and opposite side card of with discharge plate 2 connects
It is externally provided with kind of storehouse 11, this kind of storehouse 11 is passed through sowing port 12 and connected with inhaling kind of a room 9, and also has seed in the lower section of sowing port 12
Clean-up port, at ordinary times by seal cap sealing, the work of this device finishes when there remains unnecessary seed this Seed cleaning up mouth, opens seed
Remaining Seed cleaning up is fallen by clean-up port.
As shown in Fig. 4 ~ Fig. 6, housing 3 is provided with seeds scraper 20, is provided with seeds scraper in the side of housing 3 and adjusts code-disc 25,
One end of seeds scraper 20 is fixing with housing 3, the other end is fixed on seeds scraper by discharge plate adjustment axis 24 and adjusts on code-disc, this
The seeds scraper 20 at end is provided with Long Circle hole, and as shown in fig. 7, discharge plate adjustment axis 24 are eccentric shaft, so when discharge plate is adjusted
When axle 24 rotates, seeds scraper 20 can be finely tuned up and down, play different scrape kind of an effect, and in order to easy to adjust, adjust in discharge plate
A regulation pointer is fixed at the end that nodal axisn 24 is located at seeds scraper regulation code-disc 25, can adjust shown by code-disc 25 according to seeds scraper
Scale is quantitatively adjusted（Scale needs to measure in advance）, the working portion of this seeds scraper 20 be located at inhale in kind of room 9 and adjacent
The card of discharge plate 2, and scrape kind of tooth 21 meeting to be provided with to the side of suction hole 8 direction of motion, scraping kind of tooth 21 is one section of zigzag
Curve, when wiping unnecessary seed off, by means of the sawtooth work surface scraping kind of tooth 21, applies an interruption being gradually increased to seed
Impact force, makes the power that seed is subject to suddenly big or suddenly small, suddenly appears and disappear, and forms the moment temporarily eliminating external force, makes originally to adsorb more firm
A seed can have an opportunity to return to stably firm adsorbed state.And by sucker in the presence of repetitious impact force
Other absorption unnecessary seeds loosely upper are wiped off.

Actual seeding flow.
As shown in figure 4, the lower section of fall-sowing area 10 is provided with outlet slide plate 22, this outlet slide plate 22 is provided with planting block 23,
Play the purpose of guiding seeds fall, because inertia splashes after preventing seed from popping out discharge plate 2.
Aspirated-air type electric seed sowing mechanism of the present utility model, its specific works method is as follows：
Aspirated-air type electric seed sowing mechanism is vertically mounted on the kind bottom portion of seeder, and the kind by kind of storehouse 11 and seeder
Case connects, and is connected with negative-pressure air fan by negative pressure line 7, produces negative pressure in the seasonal air-suction chamber 6 of negative-pressure air fan work, thus
Discharge plate 2 both sides form certain pressure differential, and in the presence of this pressure differential, the seed inhaled in kind of room 9 is attracted to suction hole 8
On, discharge plate 2 is rotated by direct current generator 4, and the rotation due to discharge plate 2, when suction hole 8 passes through to scrape with seed
When planting plate 20, unnecessary seed is just scraped kind of tooth 21 and is weeded out, and when discharge plate 2 rotates to and leaves air-suction chamber's 6 part, is no longer subject to
Suction function, just loses the absorption affinity to seed, and now seed just leans on the weight of itself to fall, via outlet slide plate 22 with fall
Plant block 23 to fall in kind of ditch directly or by grain conductor.Discharge plate 2 continues to rotate under the driving of direct current generator 4, suction hole 8
It is again introduced into air-suction chamber 6, absorbed seed again in the presence of pressure differential, so circulation are carried out continuously seeding.
