Specific embodiment
As shown in Figure 1, anti-replay ejector blade 125 include three stage structure, be preferably an integral molding structure, i.e., upper plate 121,
Lower plate 123 and connecting plate 122, the both ends of connecting plate 122 are separately connected the lower end of upper plate 121 and the upper end of lower plate 123, and connect
The connection of plate 122 and upper plate 121 and lower plate 123 is to be smoothly connected.Cross the edge that 121 side of upper plate is arranged in kind of mouth 1251.Under
A fixing port 124 and fixing port 126 are respectively provided on 123 top and bottom of plate, the fixing port 124 and 126 is open column shape
Hole, and hole wall has opening, facilitates insertion into fixture.As shown in Fig. 2, fixing port 124,126 respectively with feed mechanism for seed procapsid 1
On ejector blade fixed column 104,113 match and be fixed on ejector blade 125 on procapsid 1, the setting of fixed column 104 and 113 exists
On 1 baseplate inner surface of procapsid, for the column structure outwardly protruded.It is designed on upper plate 121, lower plate 123 and connecting plate 122 more
A air hole 120.
The more traditional ejector blade of anti-replay ejector blade 125 increases two structures, i.e. the second seed scraping device 1252 and anti-replay
Seed retaining plate 1253.Second seed scraping device 1252 and anti-replay seed retaining plate 1253 were all disposed within neighbouring kind of the mouth excessively in 1251 lower part of kind mouth
Position, anti-replay seed retaining plate 1253 in plate be arranged, the second seed scraping device 1252 in vertical plate be arranged, the second seed scraping device 1252 be arranged
Above anti-replay seed retaining plate 1253, wherein anti-replay seed retaining plate 1253 and upper plate are at 120 °, anti-replay seed retaining plate 1253 and
For two seed scraping devices 1252 at 60 °, anti-1253 length of replay seed retaining plate is about 47mm.Due to discharge plate radius substantially 100mm, prevent
Replaying 1253 length of seed retaining plate is about 47mm, is the half or so of discharge plate radius, by experimental verification, which can both prevent
Only under gas pressure, the population at planting mouth is splashed upwards crossed kind mouth 1251, caused resowing phenomenon；Meanwhile meeting
Under the requirement of working performance, which is most short effective length, i.e., can be deteriorated lower than 47mm effect, too long, will affect discharge plate
The seeding effect (length is too long to block seed movement track in type hole) of type hole, thus the length had both been able to satisfy performance requirement,
It is simultaneously also that length reduction to most short available length is saved into material.
As shown in Figure 2,3, anti-replay ejector blade 1 pushes away kind on feed mechanism for seed procapsid 1 respectively by fixing port 124,126
Plate fixed column 104,113, which matches, is fixed on ejector blade 125 on procapsid 1, and fixed column 104 and 113 is arranged at 1 bottom of procapsid
On plate inner surface, for the column structure outwardly protruded.Equally, seed scraping device 2 in the same way, passes through fixed column and procapsid 1
It matches.Gear ring 4 is matched by the bolt on its circumference with discharge plate 3, while 5 front end axis of discharge plate locating shaft and seeding
The axis hole of disk 3 matches, while selling and discharge plate 3 is fixed on discharge plate locating shaft 5 by 5 front end pin hole of discharge plate locating shaft
On.Wherein, discharge plate 3, gear ring 4 and 5 three of discharge plate locating shaft are concentricity cooperation.Bearing 11 is by each gear in front and back
Circle 6 is fixed in the axis hole of chamber housing 7, wherein front and back retaining ring 6 matches with the front and back circumferential groove in 7 axis hole of chamber housing respectively
It closes and fixes.Discharge plate locating shaft 5 and bearing 6 are interference fit, so that discharge plate 3 is fixed in chamber housing 7.Procapsid 1
Pin passes through the mutually deserved hole of chamber housing 7 and matches with buckle 8, so that procapsid 1 is fixed in chamber housing 7.Wherein, block
8 screws 9 fixed by snap are detained to be fixed in chamber housing.Driving motor 10 is fixed by screws in 7 lower section of chamber housing.Its
In, the gear of 10 front end of driving motor is meshed cooperation with gear ring 4, to drive the rotation of gear ring 4.
When seed is when vapour-pressure type feed mechanism for seed planting mouth forms population, gas enters discharge plate and air pressure front housing from air inlet
When in the gas chamber between body, air pressure can be generated, the disturbance of air-flow will be generated to the population at planting mouth, the seed of population can occur
It splashes, so that seed flew over kind mouth during splashing, causes to replay.After increasing anti-replay seed retaining plate 1253, can have
Effect prevents seed from splashing upwards and crossed kind mouth 1251.In addition, the population in feed mechanism for seed seeding operation, at vapour-pressure type planting mouth
Seed can press and be attached on discharge plate, when reaching seed scraping device position with the rotation of discharge plate, first time will be carried out by seed scraping device
Clear kind of work will be carried out clear kind for the second time when reaching the second 1252 position of seed scraping device.Since the size of kind of mouth 1251 excessively is
According to the design of corn single seed full-size, so if crossing kind of a mouth 1251 can carry out after preceding clear twice kind of failure
Clear for the third time kind.By increasing triple clear kinds of the second seed scraping device 1252, so that the air pressure of the ejector blade with this practicability
Formula feed mechanism for seed can greatly reduce replay rate when feed mechanism for seed seeding.
