Central point is configured in vertical direction with the eccentric central point of hole line of eccentric disc, outside the fixed cover on, be located at bias
The eccentric aspiration disk with air entry, the axial line of the eccentric aspiration disk and the axle of eccentric disc is fixedly mounted with disk sidepiece
Heart line overlaps, and, rotatably on eccentric disc circumferential outer surface, the closing disk that seals is with eccentric gas for sealing closing disk
Inhale disk sealing and coordinate composition aspiration vacuum chamber, reciprocally swung on position between sealing closing disk and active disk matches somebody with somebody
Dress turns shaft type and inhales discharging tube, and the shaft type suction kind tube axis line that turns is configured in vertical direction, turns shaft type and inhales discharging tube and aspiration
Vacuum chamber connects, and on the eccentric aspiration disk internal face side lower part position relative with sealing closing disk arranges arc air-flow
Blocking boss, the arc air-flow blocking boss upper end are located at eccentric aspiration disk disc centre point horizontal diameter line position
On, and open in the noncontact that the contact sealing for blocking air-flow coordinates or connect air-flow with the negative pressure aspiration mouth for turning shaft type suction discharging tube
Cooperation is opened, is matched somebody with somebody on eccentric aspiration disk, positioned at the side-lower position of eccentric aspiration disk, sealing closing disk and active disk
Dress kind of a case, clear hairbrush of planting are fitted at the suction kind mouth of kind of case, described turn shaft type and inhale discharging tube and may pass through clear hairbrush of planting be inserted into kind
In case, so far constitute aspirated-air type low level and vertically charge seed feed mechanism for seed.
The invention using active disk, turn shaft type and inhale discharging tube, seal cover board, eccentric disc with eccentric aspiration disk
Fabricated structure, it is achieved that air-suction seeding unit low level, operation of vertically charging seed, the kind grain that can be discharged air-suction seeding unit are direct
Row is broadcast on kind of bed soil earth, eliminates seed spout, with structure novel, simple, rationally, seeding operation quality is good, precision is high,
Service-strong feature.

Specific embodiment
Below in conjunction with the accompanying drawings the invention embodiment is described in detail.A kind of vertical row of charging seed of aspirated-air type low level
Kind of device, rotatable equipped drive shaft 1 in the fixed cover 2 concentric on the end of the drive shaft 1 are fixedly mounted with active disk
3, eccentric disc 6 is packed on 2 outside of fixed cover, in the disc centre point of the eccentric disc 6 and the eccentric orfice of eccentric disc 6
Heart point line is configured in vertical direction, outside the fixed cover 2 on, be located at 6 sidepiece of eccentric disc and be fixedly mounted with air entry
11 eccentric aspiration disk 7, the axial line of the eccentric aspiration disk 7 are overlapped with the axial line of eccentric disc 6, seal closing disk
5 are rotatably arranged on 6 circumferential outer surface of eccentric disc, and the sealing closing disk 5 seals cooperation structure with eccentric aspiration disk 7
Into aspiration vacuum chamber, reciprocally swung on position between sealing closing disk 5 and active disk 3 equipped turns shaft type suction kind
Pipe 4, shaft type suction 4 axial line of discharging tube that turns are configured in vertical direction, are turned shaft type and are inhaled discharging tube 4 with company of aspiration vacuum chamber
Logical, arc air-flow blocking boss is set on the eccentric aspiration disk 7 internal face side lower part position relative with sealing closing disk 5
9,9 upper end of the arc air-flow blocking boss is located on eccentric 7 disc centre point horizontal diameter line position of aspiration disk, and
Match somebody with somebody with turning shaft type and inhaling noncontact of the negative pressure aspiration mouth of discharging tube 4 in the contact sealing cooperation or connection air-flow that block air-flow and open
Close, match somebody with somebody on eccentric aspiration disk 7, positioned at the side-lower position of eccentric aspiration disk 7, sealing closing disk 5 and active disk 3
Dress kind of a case 8, clear hairbrush 10 of planting are fitted at the suction kind mouth of kind of case 8, described turn shaft type and inhale discharging tube 4 and may pass through clear hairbrush 10 of planting insert
Enter in kind of case 8.
During operation, on fixed cover 2, the rotary motion of drive shaft 1 through active disk 3, turn shaft type inhale discharging tube 4 drive close
Envelope closing disk 5 is rotated relative to eccentric aspiration disk 7 on eccentric disc 6, and negative-pressure gas are made by sealing dome through air entry 11
The aspiration vacuum chamber that plate 5 is constituted with eccentric aspiration disk 7 produces negative pressure, when turn shaft type inhale the negative inspiratory pressure mouth of discharging tube 4 with
When arc air-flow blocking boss 9 departs from cooperation, seed is adsorbed by the shaft type suction discharging tube 4 that turns in kind of case 8, by kind hairbrush clearly
After 10 remove unnecessary seed, produce from kind of case 8；Turn to when the seed-bearing negative inspiratory pressure mouth for turning shaft type suction discharging tube 4 is inhaled
During with blocking cooperation being in contact with it at arc air-flow blocking boss 9, turn shaft type and inhale negative-pressure sucking disappearance in discharging tube 4, due to arc
The initiating terminal of shape air-flow blocking boss 9 is located at eccentric 7 disc centre point horizontal diameter line position of aspiration disk, conducts oneself with dignity in seed
Rotating with sealing closing disk 5 makes seed low level discharge in vertical direction under tangential inertial force collective effect, directly broadcast and come kind of a ditch
On soil.
