Description
Technical field
The utility model is related to a kind of wheat feed mechanism for seed, more particularly to a kind of aspirated-air type wheat feed mechanism for seed, is specially one kind
Releasing pressure automatically plants clearly Double-sucker Wheat Precision Metering Device.
Background technology
Feed mechanism for seed on current market has mechanical and two kinds of an aspirated-air type, and wherein air-suction seeding unit will be at one section of future
It is interior to occupy dominant position.The sucked type feed mechanism for seed worked out at present is the sucked type aspiration seeding using aspiration principle
Device, it has a problem not solve always when in use, when smaller seed or seed in irregular shape are by negative pressure
It is drawn onto after the aperture on sucker, inhales unusually strong under the powerful suction of negative pressure, seed scraping device can not scrapes such seed, or
The such seed of person scrapes disconnected by seed scraping device, and remaining part is remained in aspiration hole, has a strong impact on persistently using for feed mechanism for seed.
The content of the invention
The utility model in view of the shortcomings of the prior art there is provided one kind can self-relieving feed mechanism for seed, be easy to that gas will be sucked
The seed discharge of sucker.
The utility model is achieved by the following technical solution plants clearly the small malt extract amount of Double-sucker there is provided a kind of releasing pressure automatically
Feed mechanism for seed, including housing and in housing and two suckers be arrangeding in parallel with aspiration hole, two sucker is fixed on two
Hold through in the rotating shaft of the housing, be provided between two suckers on the outside of seeds scraper, the sucker and scrape kind of a position corresponding to seeds scraper
Install and be equipped with the pressure release being fixed on housing and plant pipe clearly, the pressure release is planted clearly pipe one end and contacted with sucker, the other end connects with air
It is logical, planting chamber is provided with below seeds scraper, planting bottom of chamber portion is fixed with the extraneous discharging tube of connection, when due to negative pressure it is firm
Gu when inhaling seed on aspiration hole and going to pressure release and plant pipe clearly, because pipe and atmosphere are planted clearly in pressure release, negative pressure disappears, it is easy to
Hung lower and fallen in planting chamber by seeds scraper, the seed for falling into planting chamber is discharged by discharging tube.
As optimization, kind of a case is surrounded with housing on the inside of two sucker, described kind of box top is installed with seed input pipe, by wheat seeds
Concentrate at one, be easy to the supply of wheat seeds.
As optimization, described kind of case outer surface is installed with the horizontal otic placode with mounting hole, and otic placode can be used for consolidating for kind of case
It is fixed, it can be used for kind of a case lifting.
As optimization, the outside of two sucker surrounds air chamber with housing respectively, and the plenum roof is installed with air intake duct,
Air chamber is arranged at kind of a case both sides, aspiration seeding can be carried out simultaneously, seeding efficiency is improved.
As optimization, the rotating shaft is connected by the bearing block of two settings that are spaced a distance with housing, reduces rotating shaft
Frictional dissipation during rotation, more energy-conservation.
The beneficial effects of the utility model are：Plant the setting of pipe clearly by pressure release, seed scraping device is easy to that gas will be attracted on
Seed in sucker is scraped, and extends feed mechanism for seed service life.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
A kind of releasing pressure automatically as shown in Figure 1 plants clearly Double-sucker Wheat Precision Metering Device, including housing and in housing and
Two with aspiration hole 9 seeds suckers 3 be arrangeding in parallel, two seeds suckers 3 are fixed on two ends and passed through in the rotating shaft 14 of housing, rotating shaft 14
It is connected by the bearing block 12 of two settings that are spaced a distance with housing, sealing ring is provided between bearing block 12 and housing
10, it is ensured that good seal.
The inner side of two seeds sucker 3 surrounds kind of case 4 with housing, plants the top of case 42 and is installed with seed input pipe 1, seed is entered by seed input pipe 1
Enter to kind of case 4.The horizontal otic placode 5 with mounting hole is installed with the outer surface of kind of case 4, horizontal otic placode 5 can be not only used for planting
The fixation of case 4, it may also be used for plant the lifting of case 4.
The outside of two seeds suckers 3 surrounds air chamber 8 with housing respectively, and the top of air chamber 8 is installed with air intake duct 7, passes through air intake duct 7
Negative pressure state will be drawn in air chamber 8.
Seeds scraper 13 is provided between two seeds suckers 3, kind of the position of scraping that the outside of seeds sucker 3 corresponds to seeds scraper 13 is provided with
Pipe 15 is planted clearly in the pressure release being fixed on housing, and pressure release is planted clearly the one end of pipe 15 and contacted with seeds sucker 3, the other end and atmosphere.Scrape
Plant the lower section of plate 13 and be provided with planting chamber 6, the bottom of planting chamber 6 is fixed with the extraneous discharging tube 11 of connection.
Seed is entered in kind of case 4 by seed input pipe 1 first, and blower fan is negative by being drawn in air chamber 8 by the air-breathing of air intake duct 7
Pressure condition；Seeds sucker 3 is rotated under the drive of rotating shaft 14, due to air chamber and the presence for planting pressure difference in case, is adsorbed to seed
On suction hole 9, with the rotation of seeds sucker 3, seed is brought to the position of seeds scraper 13 from the bottom of kind of case 4, and pipe 15 is planted clearly in pressure release
