For agricultural plant protection unmanned plane, due to UAV system heavily quantitative limitation, the normally high concentration agricultural chemical that unmanned plane carries, some or even suspension, traditional assembly that sprays directly is contained in and unmanned plane sprays the problems such as perishable, easy blocking appears in high concentration agricultural chemical often or medical liquid atomizing is insufficient, is therefore necessary that the assembly that sprays developing unmanned plane special solves the problems referred to above.
Utility model content
For overcoming problems of the prior art, the centrifugal spray that the utility model provides a kind of agricultural plant protection unmanned plane sprays assembly, effectively can solve the problems such as tradition to spray when assembly sprays high concentration agricultural chemical perishable, the easy blocking that occurs or medical liquid atomizing is insufficient.
The concrete technical scheme that the utility model adopts is as follows:
A kind of centrifugal spray of agricultural plant protection unmanned plane sprays assembly, comprise atomizing disk, the circle centre position of described atomizing disk is connected with transfusion axle, and this transfusion axle inside is provided with infusion channel and coordinates with the motor-driven driving atomizing disk to rotate, and the junction of bottom and atomizing disk is provided with fluid hole; The card of described atomizing disk is covered with fog water content, and the top of this fog water content is provided with the ring baffle of anti-liquid medicine spill.
In the utility model, liquid is directly delivered to the circle centre position of atomizing disk by hollow transfusion axle, the woven hose drainage of relative peripheral hardware, there is better medical liquid atomizing effect, and ring baffle is set above fog water content, effectively can prevent the weeping brought because interference causes fog water content to tilt, when fog water content tilts, if ringless-type baffle plate, part liquid may have little time to accelerate direct spilling, forms water clock.
Wherein, described atomizing disk is corrosion resistant dish-shaped plastic components, and the angle of the inclined-plane of annular and the bottom surface of level is 135 degree, and the inclined-plane of annular is distributed with described fog water content.
In the utility model, the vertical described inclined-plane of described ring baffle is arranged.
The ring baffle that straight bevel facet is arranged, has relatively high gear liquid height, when unmanned plane during flying tilts, can prevent liquid medicine spill when larger angle of inclination flight.
Wherein, described fluid hole is 4 ~ 6, square opening identical sized by fluid hole, and arranges to have the effect of dispersion liquid bottom ring transfusion axle.
Meanwhile, the top of described transfusion axle is connected with liquid medicine catheter by sealing shroud, and sealing cover can for connecting the rotation seal joint of transfusion axle and liquid medicine catheter, and while being rotatably assorted, the joining place sealing of both maintenances, avoids leakage.
Further, described liquid medicine catheter is connected with liquid inlet tube, and this liquid inlet tube is provided with flow control valve and flowmeter; Flow control valve, for controlling infusion flow, adapts with the rotating speed of atomizing disk, maintains good atomizing effect; Flowmeter, for detecting real-time infusion flow, is convenient to flow-control and adjustment.
The beneficial effects of the utility model:
The utility model structure is simple, effectively can solve the problems such as tradition to spray when assembly sprays high concentration agricultural chemical perishable, the easy blocking that occurs or medical liquid atomizing is insufficient, there is advantages such as can regulating atomized drop size, in real time adjustment spray value according to actual needs simultaneously, can be used for agricultural plant protection unmanned plane and spray high concentration liquid.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of centrifugal spray of agricultural plant protection unmanned plane sprays assembly, by atomizing disk 1 with spray control assembly 2 and form.Atomizing disk 1 is corrosion resistant dish-shaped plastic components, the dish sloped sidewall of atomizing disk and the angle of bottom surface are 135 °, inside sidewalls is covered with uniform fog water content 11, and this fog water content 11 extends along atomizing disk 1 radial direction, sidewall is equipped with the ring baffle 12 vertical with wall.Transfusion axle 13 is hollow shaft, inside is provided with infusion channel, be positioned on the rotary middle spindle of atomizing disk 1, transfusion axle 13 lower end and junction, dish-shaped atomizing disk bottom surface are provided with the large along the circumferential direction uniform square fluid holes such as 4, are thrown to atomizing disk bottom surface after liquid flows through axle of infusing under the effect of gravity and centrifugal force from 4 fluid holes.
As shown in Figure 1, spray control assembly 2 to be made up of motor 25, motor output shaft 26, driving gear 27, driven gear 28, liquid inlet tube 24, flow control valve 23, flowmeter 22 and sealing shroud 21.Driving gear 27, driven gear 28 form first stage decelerator, pass to transfusion axle 13 after being reduced by the rotating speed of motor 25, and transfusion axle 13 upper end is connected with liquid medicine catheter by sealing shroud 21.
During centrifugal spraying part work, first unmanned aerial vehicle control system sends signal enabling motor 25, motor drives transfusion axle 13 High Rotation Speed by reduction gearing, atomizing disk 1 and transfusion axle 13 synchronously wait rotating speed to rotate, then medicinal liquid flow is controlled by flow control valve 23 according to actual required spray value, after flowmeter 22 detects actual flow, liquid is through liquid medicine catheter, the atomizing disk 1 of High Rotation Speed is flowed into after transfusion axle 13, due to the effect of centrifugal force, liquid can upwards accelerate flowing along the fog water content 11 of atomizing disk centrifugal atomizing dish sidewall, atomizing disk is thrown away at a high speed finally by fog water content top, the high speed liquid thrown away and air interact and are atomized, finally be deposited on crop.
The rotating speed of motor 25 determines the rotating speed of atomizing disk 1, and then determines the speed that liquid throws away, and the speed that liquid is thrown out of is larger, and medical liquid atomizing is more abundant, should decide motor speed in reality according to the physicochemical property of the droplet sizes of plant protection best results and liquid.The ring baffle 12 of atomizing disk 1 effectively can prevent the weeping brought because interference causes atomizing disk to tilt, and when atomizing disk tilts, if ringless-type baffle plate 12, part liquid may have little time to accelerate directly to overflow atomizing disk and produce water clock.The spray value of unit interval and unmanned plane forward flight speed, working width, liquor strength are relevant, can be controlled the spray value of unit interval by flow control valve 23 together with flowmeter 22.
The foregoing is only better implementation example of the present utility model, be not limited to the utility model, all within the utility model spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
