Description
Technical field
The present invention relates to agricultural aviation apparatus field, more particularly to a kind of live streaming unit driven by unmanned plane.
Background technology
Agricultural Mechanization Degree is higher and higher.With the development of science and technology, carrying out Crops in Applying Fertilizer, spray by manual control aircraft
The work such as pesticide, sowing are spilt, develops to and the work such as Crops in Applying Fertilizer is carried out by unmanned plane, sprays insecticide, sow.However, broadcasting
Kind field, current most of unmanned aerial vehicles sowing are fallen on soil with being all based on the free gravity of seed.For paddy field class
Soil, seed can fall into soil and root due to dead weight and after the movement of falling object.But for nonirrigated farmland or dry ground
Ground can only stay in soil surface when seed is that freely falling body is fallen, at this point, since land surface temperature is higher and arid,
Seed is difficult germination, and the survival rate of seed is extremely low, even results in mistake and receives.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of seed to sow uniform essence
It is accurate, to sow density adjustable and can effectively improve the live streaming unit of seed viability.
The technical solution adopted in the present invention is：The present invention includes unmanned plane, and at least one is provided on the unmanned plane
Group sowing mechanism, the sowing mechanism includes seed-box, dispenser and blowing device, and flow is provided on the dispenser
Adjuster, the dispenser, the blowing device and the flow regulator with the flight control system telecommunications of the unmanned plane
Number connection, is located at the seed in the seed-box after the dispenser seeding, according to the flying speed of the unmanned plane,
The flow regulator adjusts flow rate, and the blowing device adjusts air quantity and wind speed, and seed is accelerated equal by the blowing device
It is blown to ground evenly.
By said program as it can be seen that by by seed-box, dispenser and blowing device Combination Design so that from dispenser
The plantation of discharge is by after the blowing power-assisted of blowing device, seed being rolled into a ball and is disperseed, avoids luming, then post directive soil,
So that seed, which either still does paddy field class soil in ground class soil, can be improved seed in the adhesive force on soil surface, this has
The moisture in soil is touched conducive to seed, to greatly increase the survival rate of seed, in addition, passing through the dispenser
Setting, it is ensured that the seed that is discharged out of described seed-box is evenly dispersed not to lump, and realizes seed by flow regulator
Sowing is uniform, and density is adjustable, ensure that the growing way after germination；In addition, by having the unmanned plane of terrain following module, it is real
Existing sowing mechanism is consistent always at a distance from ground, and the height of unmanned plane during flying is sufficiently low, this low-latitude flying cooperation blowing
The power-assisted of device can effectively avoid nature beam wind to the interference of seeds fall, prevent seed during whereabouts by nature
Lateral wind must be drifted and is scattered everywhere, and seed is caused to fall to the ground uneven and influence harvest.
Further, the dispenser includes being arranged in the seed separator frame of the seed lower box part and setting described
Sowing port below seed separator frame, the seed separator frame are made of several shims, and the flow regulator is arranged in institute
It states on seed separator frame, the blowing device is arranged the side in the outlet of the seed separator frame, and the blowing device will be from
The seed of the seed separator frame discharge blows injection from the sowing port.
Said program as it can be seen that by the setting of dispenser can effectively seed-dispersed distribution, and density is adjustable, avoids
The seed for being blown to soil surface is unevenly distributed, and ensure that the growing way after germination.
Still further, the flow regulator can be include setting seed separator frame end and with the nothing
It is several at the first motor of man-machine flight control system electric signal connection and the sowing port being arranged below the seed separator frame
A roller, kind of a sub-trenches are provided on the surface of the roller, and the first motor drives the roller rotation, is located at described kind
Seed in sub- case drops into described kind of sub-trenches, and the first motor drives the roller rotation, and seed is by the roller
Take the lower part of the seed separator frame to from the top of the seed separator frame；It can also be including the winged control with the unmanned plane
The electromagnetic valve switch of system electric signal connection and the valve being connected with the electromagnetic valve switch, the valve are that several transverse directions are set
The soft board or hairbrush at the seed separator frame and between shim described in adjacent arbitrary two panels are set, it is several described soft
Plate or hairbrush are integrally formed by connecting rod constitutes the valve.
Said program on seed separator frame as it can be seen that by being arranged flow regulator, by the adjusting of flow regulator, and
The flight control system electric signal of flow regulator and unmanned plane connects, and can adjust flow tune according to the flying speed of unmanned plane accordingly
The aperture of flow regulator is turned up when unmanned plane during flying speed is higher for the flow velocity for saving device so that the speed of seed discharge carries
Height ensures that seed falls within the consistent in density on soil；When unmanned plane during flying speed is relatively low, by the aperture tune of flow regulator
It is low so that the speed of seed discharge reduces, and ensures that seed falls within the consistent in density on soil, ensures the space of germination.
Further, the top of the seed separator frame is provided with check-valves.It can be seen that setting by check-valves
It sets, can prevent seed from flowing back under the action of blowing device seed-box, ensure that seed is successfully discharged and is blown from dispenser and penetrates
To soil, avoid flogging a dead horse.
Again further, the sowing port is provided with seed import, seed export and air inlet, the air inlet band
Be connected camberedly with the seed export, the seed import is connected with the lower part of the seed separator frame, it is described into
Air port is connected with the exhaust outlet of the blowing device, and the seed export is downward.
Said program makes the wind that blowing device is blown out and the seamless knot of seed as it can be seen that by the special setting of seeding mouth structure
It closes, greatly increases the smoothness of seeds fall, ensure that not being destroyed before planting for seed, improve survival rate.
Further, the blowing device includes fan blade, drives the second motor of the fan blade rotation and be located at
The fan housing of the fan blade periphery, the exhaust outlet are arranged on the fan housing.It can be seen that blowing device is simple in structure, and by
Second motor provides power, and the second motor can be variable-frequency motor, ensure that wind-force is adjustable, make to blow for different land status
The wind-force gone out can rightly squeeze into seed in soil, meet the sowing of different vegetable seeds.
In addition, the unmanned plane includes propeller, rotor arm, flight control system and the power supply electricity being hung on the rotor arm
Source, the flight control system include terrain following module, and the sowing mechanism is hung on the rotor arm；It can be seen that logical
Cross control of the flight control system to unmanned plane and sowing mechanism, can efficiently, favorably accomplish the sowing of seed, and by power supply
Power supply, ensure that the operating time of unit, greatly reduces the labor intensity of staff.
Further, the variable amounts of the sowing mechanism on the rotor arm are hung on, the rotor arm is hung on
On the sowing mechanism it is symmetrical, the power supply be lithium ion power accumulator or fuel cell.It can be seen that right
In the unmanned plane for having different dynamic, the sowing mechanism of different number can be set, greatly extend sowing function, and can realize
Large area, different seed mixed seedings and other effects, and sowing mechanism is symmetrical on rotor arm, has greatly improved unmanned plane
Security reliability.
