Power；The seeding hubcap 6 is located at 19 shaft end of feed shaft, for protecting feed shaft 19.
As shown in Figures 1 to 10, the present invention is formed by with lower part：
(1) for kind of a device：Seed enters plants case 1 by upside plants case mouth, through entering seed chamber 16 for kind of an amount adjustable plate 14, leads to
It crosses and changes the position for kind of amount adjustment axis 12 in adjusting sliding slot 9 for kind of amount to control for kind of the angle of amount adjustable plate 14 and then control
System enters the grain weight in seed chamber 16, prevents because seed excessively causes seeding to block in seed chamber 16,16 back lower place of seed chamber
Equipped with for observation transparent cover plate 15 and while blocking unload kind unload kind of device 10, in for kind of failure of apparatus or seed chamber 16
When kind amount is excessive influences sowing, can remove and unload kind of device 10 and take out in seed chamber 16 seed, it is to be adjusted it is good after, pacify again
Dress, work；16 left side of seed chamber is enclosed enclosure space, limitation seed flowing by discharge plate 4 and 1 shell of plants case.
(2) seed fetching equipment：The negative pressure gas flow that negative-pressure air fan generates enters the arc in gas chamber shell 7 by negative pressure inlet pipe 8
Shape gas chamber 28 forms the subnormal ambient that air pressure is far below standard atmospheric pressure, by the suction kind type hole 22 on discharge plate 4 to seed chamber
Seed in 16 generates adsorption capacity.When negative pressure system works, inhales kind of type hole 22 and pass through seed at 28 left end beginning of arc gas chamber
The seed through stirring the agitation of discharge plate 27 is adsorbed when room 16 from population, then seed does circumference under adsorption force with discharge plate 4
Movement, on the upside of shield kind baler 25, the vertical component that seed generates due to gravity is provided seed by shield kind baler 25 at this time
Holding power balances, and shield kind baler 25 plays supporting bracket role to inhaling the seed that kind of mouth 22 adsorbs, it is ensured that and seed is not fallen,
Power of fan is reduced while reducing leakage sowing rate；When a suction kind type hole 22 adsorbs more seeds, the seed having more can be in seeding
4 turns of disk through falling into seed chamber 16 again when clear kind of hairbrush idler wheel 20 under the action of hairbrush idler wheel 20, it is ensured that monoseeding；Work as kind
Son inhales kind of type hole 22 negative-pressure sucking after moving at 28 right end end of negative pressure chamber disappears, and shield kind baler 25 is on seed at this time
Side, to seed gravity without effect, seed does freedom in the vertical direction only by gravity through kind of the mouth that unloads on gas chamber shell 7
Seeding operation is completed in falling.
(3) cleaning device：It is to pass through just that clear kind of 20 outer rim of hairbrush idler wheel inhales kind of the distance at 22 center of type hole away from discharge plate 4
1 seed；The extra seed that discharge plate 4 carries is pushed with the clear kind of collision of hairbrush idler wheel 20 and then is fallen after rise in seed chamber 16, clearly
Kind hairbrush idler wheel 20 rotates under the pushing of extra seed, avoids damage to seed.
(4) power plant：The power of tractor rear output shaft outflow is reached through grain (box) drive 2 in gear-box 3
Bevel-gear sett, a bevel gear is mounted in gear-box 3 to be connected with transmission device 2, another is mounted on feed shaft 19, into
And feed shaft 19 and discharge plate fixed thereon 4 are driven, discharge plate 27 is stirred and rotates coaxially.
The present invention provides a preferred embodiments, below using the operation of virus-free miniature potato sowing as embodiment, but not
With limiting the scope of the invention：
Embodiment：
The present invention is assembled by transmission device, for kind of a device, seed fetching equipment, cleaning device by fastener.Detoxification is micro-
Type potato enters plants case 1 by upside plants case mouth, through being prevented because of seed in seed chamber 16 for kind of an amount for kind of quantity regulating device control
Excessively seeding is caused to block, 16 right back of seed chamber is equipped with the transparent cover plate 15 for observation and that is unloaded kind when blocking unloads kind of a dress
10 are set, 16 left side of seed chamber is enclosed enclosure space by discharge plate 4 and 1 shell of plants case, and limitation seed flowing is formed closed
Seed chamber 16.According to the material characteristic of virus-free miniature potato, the angle adjustment for kind of amount adjustable plate 14 is carried out.
When start-up operation, power reaches gear-box 3 through transmission device 2 after being spread out of by tractor transmission shaft and drives therein one
Bevel gear 18 is rotated, a bevel gear 18 is mounted in gear-box 3, another is mounted on feed shaft 19, and then the row of drive
It plants axis 19 and discharge plate fixed thereon 4 and stirs discharge plate 27 and rotate coaxially.Negative-pressure air fan generate negative pressure gas flow by negative pressure into
Tracheae 8 enters the arc gas chamber 28 in gas chamber shell 7, forms the subnormal ambient that air pressure is far below standard atmospheric pressure, passes through seeding
Suction kind type hole 22 on disk 4 generates adsorption capacity to the seed in seed chamber 16.Seed does circle under adsorption force with discharge plate 4
Zhou Yundong, in 25 upside of shield kind baler, the vertical component that seed generates due to gravity is provided seed by protecting a kind baler 25 at this time
Holding power balance, shield kind baler 25 plays supporting bracket to inhaling the seed that kind of type hole 22 is adsorbed and works, it is ensured that seed does not fall
It falls, power of fan is reduced while reducing leakage sowing rate；The negative pressure that kind of type hole 22 is inhaled after seed movement goes out arc gas chamber 28 is inhaled
Power disappears, and shield kind baler 25 is on the upside of seed at this time, and to seed gravity without effect, seed is only by gravity, in vertical direction
On do the movement of falling object, complete seeding operation.
This example is used for virus-free miniature potato sowing operation, the line number of seeding operation can according to actual needs to device into
Row increases or reduces.In addition, the present apparatus preferably can be applied to other big grain size seed seeding operations, according to different big grain size kinds
The agriculture requirement of sub- crop can be appropriately arranged with feed mechanism for seed number in line with essence amount, efficient principle, and not pair operation line number does not have simultaneously
It is limited, the improvement done applied to the sowing of other large seeds to the present apparatus is also within the scope of the present invention.
