Description
Technical field
The invention belongs to agricultural machinery, relates generally to air-suction seed metering device.
Background technique
Current air-suction seeding unit mostly uses negative pressure sucker to complete the suction of seed, row's operation.Such air-suction seeding unit is not
There is only outside structure size significantly defect, especially during cutting off the seeding of air-negative-pressure suction, seed can only be relied on
Self weight the seed being adsorbed on negative pneumatic tray stomata is discharged from sucker hole.Production operation practice in find, it is single according to
After cutting air-negative-pressure, it is self-possessed by seed and carries out seeding, the seeds-blocking phenomenon that seed cannot be discharged frequent occurrence, leakage sowing rate mentions
Height, seeding quality decline, and as the extension of activity duration, seeds-blocking phenomenon can increase, leakage sowing rate is in rising trend.
Summary of the invention
The purpose of the invention designs a kind of centrifugation pin type aspirated-air type aiming at the above-mentioned problems of the prior art
Feed mechanism for seed reaches simple and reasonable for structure, compact, seeding is reliable, leakage sowing rate is low, operation quality is good, service-strong purpose.
The purpose of the invention is achieved in that centrifugation pin type air-suction seed metering device includes plants case, in plants case upper portion
It is successively parallel to each other from top to bottom at position and is rotatably equipped with drive shaft and servo axis, be fixedly mounted with drive chain in the drive shaft
A and drive sprocket B is taken turns, sprocket-type actuating sleeve is packed on servo axis, and sprocket-type needle stand is rotatably sleeved on servo axis, chain
A set fits on drive sprocket A and sprocket-type actuating sleeve, and chain B is sleeved on drive sprocket B and sprocket-type needle stand, servo-actuated
The axial centre position of axis is equipped with negative pressure air flue, and multiple suctions kind are along the circumferential direction successively uniformly installed on sprocket-type needle stand
Needle, the negative pressure air flue cooperate or separate closing cooperation in unlatching is connected to each suction kind needle inner hole, in multiple suctions kind needle circumference
Contain flexible shield kind band of the configuration there are gap, the flexible shield kind band medial surface and multiple suctions kind needle external end head at outside left
In shield kind cooperation, the flexible shield kind band is successively sleeved in belt roller I, belt roller II, belt roller III, belt roller IV and belt roller V in support
Cooperation, the belt roller I are driven roller, and gas nozzle and grain conductor, the gas is arranged at the flexible shield kind band gap position
Body nozzle and suction kind needle external end head cooperation, grain conductor are located at the lower section of gas nozzle.
The invention is inhaled kind using rotary kind of needle negative pressure of inhaling, when seeding, while kind of needle negative-pressure sucking is inhaled in cutting,
Seed in the case where the suction kind needle centrifugal force and gas nozzle to make rotating motion sprays gas blowing force, is completed seed and is unloaded from suction kind needle again
Under seeding operation, have seeding is reliable, leakage sowing rate is low, operation quality is good, uses reliable, structure novel, reasonable, compact spy
Point.

Specific embodiment
The invention embodiment is described in detail with reference to the accompanying drawing.A kind of centrifugation pin type air-suction seed metering device packet
Plants case 11 is included, be successively parallel to each other from top to bottom above the plants case 11 at position and is rotatably equipped with drive shaft 3 and servo axis
9, drive sprocket A1 and drive sprocket B2 are fixedly mounted in the drive shaft 3, sprocket-type actuating sleeve 14 is packed on servo axis 9, chain
Wheeled needle stand 13 is rotatably sleeved on servo axis 9, and chain A15 set fits on drive sprocket A1 and sprocket-type actuating sleeve 14,
Chain B4 is sleeved on drive sprocket B2 and sprocket-type needle stand 13, and negative pressure air flue is equipped on the axial centre position of servo axis 9
8, multiple suction kind needles 12, the negative pressure air flue 8 and each suction kind are along the circumferential direction successively uniformly installed on sprocket-type needle stand 13
12 inner hole of needle opens cooperation or partition closing cooperation in connection, contain at multiple suction kind of 12 periphery position of needle configure there are
The flexible shield kind band 6 of gap, flexible shield kind 6 medial surface of band and multiple suctions kind 12 external end head of needle are described soft in shield kind cooperation
Property shield kind of a band 6 be successively sleeved in belt roller I 5, belt roller II 16, belt roller III 17, belt roller IV 10 and belt roller V 18 in support cooperation, institute
Stating belt roller I 5 is driven roller, and gas nozzle 7 and grain conductor 19, the gas is arranged at the flexible shield kind 6 gap position of band
Nozzle 7 and suction kind 12 external end head of needle cooperation, grain conductor 19 are located at the lower section of gas nozzle 7.
When operation, the rotary power of drive shaft 3 passes through drive sprocket A1, chain A15, sprocket-type actuating sleeve 14 and drive chain
Wheel B2, chain B4, sprocket-type needle stand 13, which respectively drive servo axis 9 and inhale kind of needle 12, to be rotated, while as the belt roller of driven roller I 5
Flexible shield kind band 6 is driven to turn round under the support of belt roller II 16, belt roller III 17, belt roller IV 15 and belt roller V 18, when in suction kind needle 12
When hole is connected to the unlatching of negative pressure air flue 8, in negative pressure air flue 8 under negative-pressure pneumatic absorption, inhales kind of a needle 12 and adsorb kind out of plants case 11
After son, continue to rotate, the suction kind needle 12 of absorbed seed, which enters in the flexible range comprehension for protecting kind of band 6, carries out shield kind, prevents seed
It falls off, when at the gap position that suction kind needle 12 turns to flexible shield kind band 6, negative pressure air flue 8 is cut with suction kind 12 inner hole of needle closing
It is disconnected, while negative-pressure sucking disappears in inhaling kind of 12 inner hole of needle, by the self gravity and rotary centrifugal force of the seed being adsorbed
And 10 strength of gas nozzle is blown down, the unification of three power unloads seed from suction kind needle 12, is discharged into grain conductor 19, completes seeding
Operation.
