Abstract
A hemispherical suction nozzle of a vegetable seed seeding apparatus comprises a suction nozzle mounting body, a suction nozzle, a suction hole, a hemispherical suction port, a circular air suction port, a conical air suction port, a notch groove and threads; the novel vegetable seed sucker is characterized in that the sucker is fixed on the sucker mounting body through threads, the top surface of the sucker and the top surface of the mounting body are located on the same plane, a sucker hole is formed in the sucker, the sucker hole is composed of a hemispherical sucker, a circular air suction opening and a conical air suction opening, the radius of the hemispherical sucker is equal to the maximum diameter of a vegetable seed, and the notch groove can be used for placing a disassembling tool. The suction nozzle can greatly improve the adsorption capacity of the suction nozzle, can realize the seeding of hemispherical vegetable seeds, reduces the reseeding rate of the seed sowing device, and is favorable for realizing the high-speed precision seeding of the seed sowing device.
Description
Technical field
The present invention relates to a kind of hemispherical green vegetables seed metering device suction nozzles, belong to agricultural machinery technological field, particularly suitable
In the absorption of subsphaeroidal green vegetables seed.
Background technique
The core component of seeder is feed mechanism for seed, and the performance of feed mechanism for seed is to determine the key factor of precision drilling.It answers at present
With being most widely air-suction seeding unit, which, which has, damages the spies such as small, versatile, suitable high speed sowing to seed
Point.Air-suction seeding unit mostly uses discharge plate to separate seed and negative pressure chamber, passes through negative pressure using the type hole on discharge plate
Seed is adsorbed, seed is then transported by negative pressure chamber by the rotation of discharge plate and completes seeding.But it is the shape of type hole, big
The factors such as small, negative pressure value are affected to the absorption property of seed, often occur inhaling again, leak the problems such as suction, type hole blocking, serious shadow
Ring the precision drilling of seeder.
Summary of the invention
The technical problem to be solved by the present invention is to propose one to overcome the problems, such as that air-suction seeding unit discharge plate is existing insufficient
Kind hemispherical suction nozzle design, avoids inhaling again caused by due to green vegetables seed quality is light and in irregular shape, leaks suction phenomenon.
To solve the above problems, the present invention is achieved by the following technical solutions: a kind of hemispherical green vegetables seed seeding
Device suction nozzle is that kind of mouth (4), round air inlet (5), taper suction are inhaled by suction nozzle fixing body (1), suction nozzle (2), sucker (3), hemispherical
Air port (6), gap slot (7) and screw thread (8) composition, it is characterised in that: the suction nozzle (2) is fixed on installation by screw thread (8)
On body (1), the top surface of suction nozzle (2) and the top surface of fixing body (1) are generally aligned in the same plane, and sucker (3), sucker are formed in suction nozzle (2)
(3) it is formed with hemispherical in and inhales kind of mouth (4), round air inlet (5) and taper air inlet (6), the hemispherical inhales kind of mouth (4)
Radius is equal with the maximum gauge of green vegetables seed, and the gap slot (7) can be used for placing dismantling device.
The present invention can inhale the suction kind that kind of port radius size realizes the subsphaeroidal seed of different-grain diameter by changing hemispherical,
It can be connected through a screw thread the suction nozzle of replacement different size, it is easy to operation.
Detailed description of the invention
Fig. 1 is the schematic diagram of hemispherical green vegetables seed metering device suction nozzle of the present invention.
Specific embodiment
As shown in Figure 1, hemispherical vegetable seeds feed mechanism for seed suction nozzle, be by suction nozzle fixing body (1), suction nozzle (2), sucker (3),
Hemispherical inhales kind of mouth (4), round air inlet (5), taper air inlet (6), gap slot (7) and screw thread (8) composition, feature and exists
In: the suction nozzle (2) is fixed on fixing body (1) by screw thread (8), the top surface of suction nozzle (2) and the top surface position of fixing body (1)
Be formed in same plane, suction nozzle (2) sucker (3), be formed in sucker (3) hemispherical inhale kind of mouth (4), round air inlet (5) and
Taper air inlet (6), the radius of the hemispherical suction kind mouth (4) notch equal with the maximum gauge of green vegetables seed, described
Slot (7) can be used for placing dismantling device.
Above with it is preferable implementation disclose the present invention, so it is not intended to limiting the invention, it is all take equivalent replacement or
Equivalent transformation technical solution obtained, falls within the scope of protection of the present invention.
Claims (2)
1. hemispherical vegetable seeds feed mechanism for seed suction nozzle is to inhale kind of a mouth by suction nozzle fixing body (1), suction nozzle (2), sucker (3), hemispherical
(4), round air inlet (5), taper air inlet (6), gap slot (7) and screw thread (8) composition；It is characterized by: the suction nozzle
(2) it is fixed on fixing body (1) by screw thread (8), the top surface of suction nozzle (2) and the top surface of fixing body (1) are generally aligned in the same plane, and are inhaled
It is formed in mouth (2) sucker (3), hemispherical is formed in sucker (3) and inhales kind of mouth (4), round air inlet (5) and taper air inlet (6),
The gap slot (7) can be used for placing dismantling device.
2. hemispherical vegetable seeds feed mechanism for seed suction nozzle according to claim 1, it is characterised in that the hemispherical inhales kind
The radius of mouth (4) is equal with the maximum gauge of green vegetables seed, and such structure can tightly adsorb seed, reduce suction rate and leakage again
Suction rate.
