Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present invention is described in detail.A kind of air-suction seeding unit breaks pressure kind and machine
Tool forces seeding combined mechanism to include feed mechanism for seed frame 2, is fixedly mounted with negative-pressure pipeline flange on described feed mechanism for seed frame 2 outer side center position
Dish 6, is fixedly mounted with that the power input shaft 4 of driving wheel 3 is rotating to be arranged on feed mechanism for seed frame 2 sidewall, inside described feed mechanism for seed frame 2
The negative pressure air flue connector drum 7 being interconnected with negative-pressure pipeline ring flange 6, the fixing suit of outer sleeve body 8 it is fixedly mounted with on wall centre
On outside negative pressure air flue connector drum 7, it is fixedly mounted with that the negative pressure cavity housing 9 of driven pulley 5 is rotating to be fitted on outer sleeve body 8, institute
State driving wheel 3 to be connected with each other with driven pulley 5, described negative pressure cavity housing 9 outboard end seals and is fixedly mounted with interior discharge plate 15, in institute
Stating and be fixedly mounted with outer discharge plate 14 on interior discharge plate 15 circumferential edges side, the equipped machinery being axially movable on interior discharge plate 15 is strong
Seeding pin 12 processed, mechanical forced seeding pin 12 coordinates or departs from insertion cooperation with the suction hole 16 on outer discharge plate 14 in inserting,
Sealing ring 11 is sleeved on mechanical forced seeding pin 12, and described sealing ring 11 coordinates with interior discharge plate 15 in contacting or disengages
Coordinating, recoil press spring 13 set fits on mechanical forced seeding pin 12 1 sidepiece, and one end of described recoil press spring 13 is strong at machinery
Axially positioning on seeding pin 12 processed, its other end contacts cooperation with outer discharge plate 14, on described outer sleeve body 8, is positioned at negative pressure cavity
Between housing 9 and interior discharge plate 15, position is fixedly mounted with seeding cam disc 10, described seeding cam disc 10 and mechanical forced seeding pin
12 contacts coordinate, and plant chamber outer housing 1 and are fixedly arranged at vacuum cavity 9 outside left.In described outer discharge plate 14 end face outside
Above, between adjacent suction hole 16, position is radially provided with strip groove 17.
During operation, the power input shaft 4 of rotation drives negative pressure cavity housing 9 on outer sleeve body 8 by driving wheel 3, driven pulley 5
Rotating, negative pressure cavity housing 9 drives outer discharge plate 14 and mechanical forced seeding pin 12 to rotate through interior discharge plate 15 in the lump, same with this
Time, negative pressure cavity housing 9 is contained with interior discharge plate 15 by negative-pressure gas by negative-pressure pipeline ring flange 6, negative pressure air flue connector drum 7
The chamber Xi Cheng vacuum chamber constituted, when mechanical forced seeding pin 12 turns in seeding cam disc 10 pit, at return
Under stage clip 13 effect, mechanical forced seeding pin 12 axially moves on interior discharge plate 15, and from the suction hole of outer discharge plate 14
Extracting in 16, the negative-pressure sucking in vacuum chamber will be located in interior discharge plate 15, outer discharge plate 14 and the kind planted between chamber outer housing 1
Son absorption is on suction hole 16, when mechanical forced seeding pin 12 turns to seeding cam disc 10 boss position, promotes machinery strong
The reverse axially-movable of seeding pin 12 processed, and be inserted in the suction hole 16 of outer discharge plate 14, Tong Bu with this, sealing ring 11 quilt simultaneously
It is squeezed between mechanical forced seeding pin 12 shoulder and interior discharge plate 15 end face, cuts off the negative pressure on suction hole 16, in disconnected pressure
Meanwhile, the seed mechanical forced on suction hole 16 is also released by mechanical forced seeding pin 12, departs from seeds sucker, completes disconnected pressure and machine
Combination operation forced by tool.When discharge plate 14 rotates outside, outside in discharge plate 14 end face outside, between adjacent suction hole 16
The strip groove 17 that position is arranged radially plays constantly seed effect in agitation kind chamber outer housing 1 so that it is motion, to carry
The effect that seed is adsorbed on suction hole 16 by high negative pressure power, it is ensured that seed-filling rate.
