Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As the embodiment one of unmanned plane solid material blowing device of the present invention, as shown in Figures 1 to 4, including object
Hopper 1 blows barrel 2 and ducted fan 3, and the one end for blowing barrel 2 is arranged in the ducted fan 3, and 1 lower end of body feed tank is equipped with
Discharge port 11, the barrel 2 that blows are connected to discharge port 11, and material enters from discharge port 11 blows barrel 2, and by ducted fan 3
Blow barrel 2.Such mode is particularly suitable for powder or lighter particulate material.
The unmanned plane solid material blowing device no longer uses traditional centrifugal fan, but uses ducted fan 3,
As shown in figure 3, ducted fan 3 is a kind of aerofoil fan, there is duct, air-out direction is parallel with flabellum rotation axis, and weight is small, body
Product is also small, is conducive to the continuation of the journey of unmanned plane, and the revolving speed of ducted fan 3 can achieve tens of thousands of turns per minute, and air output is bigger,
It is more preferable to blow material effect.
In the present embodiment, the blowing device further includes conically shaped 8, and the setting of conically shaped 8 is being blown in barrel 2, with
Ducted fan 3 is adjoining, and 8 one end of conically shaped is bonded with the inner wall for blowing barrel 2, and another end opening is smaller, and is located at discharge port 11
Lower edge.The wind of ducted fan 3 is blown into from the big opening end of conically shaped 8, is blown out from osculum end, can shape at such discharge port 11
At negative pressuren zone(A small distance above the air duct that conically shaped is formed, between discharge port lower section), not but not stop blanking, and
And certain suction is formed, promote blanking, so blanking effect is significantly improved.
In the present embodiment, the blowing device further includes motor 4, shaft 5 and puddle support 6, and the shaft 5 is arranged in object
Inside hopper 1, the puddle support 6 is arranged in shaft 5, and the motor 4 drives shaft 5 and puddle support 6 to rotate.Puddle support 6 is tight
The inner surface of body feed tank 1 is against, is close to that proper abutting that not refers to the gap is zero, herein in order to avoid the two
Interference generates friction when rotation, designs certain gap and be also necessary.For some short grained materials or powder,
It is easy to inhale wall, causes material to block and be unable to blanking.The puddle support 6 of the present embodiment can be stirred using scraped wall method,
It can thoroughly prevent to inhale wall phenomenon, belong to three-dimensional stirring, stirring range is big, and mixing effect is very good.
In the present embodiment, screw rod 7 is additionally provided in the shaft 5, the screw rod 7 is arranged at discharge port 11.Screw rod 7 is every
Rotation is turned around, and the material taken out of is fixed, so only needing to adjust the revolving speed of motor 4, so that it may control the flow of blanking, energy
Fully ensure that the uniformity of blanking.
The motor 4 is stepper motor, and revolving speed is easily controllable, is not influenced by load variation.Stepper motor is Jiang electricity Mai
The opened loop control motor that signal is changed into angular displacement or displacement of the lines is rushed, is that main in modern digital program control system executes member
Part, application is extremely wide, and in the case where non-overload, the revolving speed of motor, the position of stopping are solely dependent upon the frequency of pulse signal
And umber of pulse controls the velocity and acceleration of motor rotation by control pulse frequency without being influenced by load variation, from
And achieve the purpose that speed regulation.
In the present embodiment, 5 upper end of shaft is fixed on 1 top of body feed tank, the discharge port by first bearing 20
Punishment in advance ring 9 is equipped at 11, the punishment in advance ring 9 is equipped with second bearing 30, and 5 lower end of shaft is arranged in second bearing 30,
The puddle support 6 is arranged in shaft 5, and the motor 4 drives shaft 5 and puddle support 6 to rotate.5 upper and lower ends of shaft are by axis
It holds and fixes well, smooth rotation, frictional force is small, long service life, and material can be entered and be blown from the 9 inside blanking of punishment in advance ring
In barrel 2, since shaft 5, punishment in advance ring 9 are being blown above 2 air duct of barrel, to blow without any blocking in barrel 2, outlet air is smooth,
It is good to blow material effect.
In the present embodiment, as shown in figure 4, the punishment in advance ring 9 includes outer ring 91 and inner ring 92, the outer ring 91 and inner ring
92 are connected by connecting rod 93, and punishment in advance area is formed between outer ring 91 and inner ring 92, and the second bearing 30 is arranged in inner ring 92.
More specifically, 93 quantity of connecting rod is three, the angle between adjacent connecting rod 93 is 120 degree, and punishment in advance area is larger, benefit
In blanking.
Certainly, the connecting rod quantity is four, and it is also feasible that the angle between adjacent connecting rod, which is 90 degree,.
In the present embodiment, the blowing device also packet height-gauge 50 and computing unit, the height-gauge 50
The top of body feed tank 1 is set, and the height-gauge 50 is used to measure the height of surplus material in body feed tank 1, the calculating
Unit is used to go out according to the altitude conversion of surplus material in body feed tank 1 capacity of surplus material.
The height-gauge 50 is that laser range finder, infrared range-measurement system or millimetre-wave radar rangefinder, use are non-contact
Formula mode measures the height of material, and accuracy of measurement is high, and error is small;Since 1 shape of body feed tank has been fixed, body can be passed through
Product calculation formula calculates material surplus, also can use corresponding table of the height of materials with material surplus, is tabled look-up to obtain material
Surplus.User can obtain material surplus in real time, very convenient.The computing unit is the computing unit in flight control computer,
Height-gauge 50 will transfer data to flight control computer in real time, and flight control computer is by altitude conversion at the appearance of surplus material
Amount, makes full use of the existing resource of unmanned plane, it is not necessary to individually increase computing unit.The blowing device further includes alarm unit,
The alarm unit is used to be alerted when material surplus is lower than preset value, to remind user, copes in advance.Motor 4 is simultaneously
Screw rod 7 and 6 Stirring of puddle support are driven, the smooth blanking of material can not only be made, the upper surface of material can also be made relatively more flat, this
It is most accurate that sample height-gauge surveys the data that 50 go out.
As the embodiment two of unmanned plane solid material blowing device of the present invention, as shown in figure 5, not with embodiment one
It is that the body feed tank 1 includes half hopper 12 of a left side and right half hopper 13 with place, under left half hopper 12 and right half hopper 13
End is equipped with discharge port 11, is equipped at each discharge port 11 and blows barrel 2 and ducted fan 3.Because blowing barrel 2 with direction
Property, being arranged two groups blows barrel 2 and ducted fan 3, can blow material to the left simultaneously and blow material to the right, and working area is bigger.
In the present embodiment, the upper half of left half hopper 12 and right half hopper 13 is to share space, can effectively be kept away
Exempt from half hopper 12 of a left side and right half hopper 13 feeds unbalanced, influences the flight balance of unmanned plane.Since the revolving speed of two shafts 5 is
It is identical, so the discharging speed at two discharge ports 11 is also identical, symmetery.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
