Reference signs in the attached figures:
The following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the attached figures in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
As shown in
Specifically, in this embodiment, when feces in a poultry house is collected, the unmanned aerial vehicle body 100 is controlled to fly in the poultry house through the wireless controller, so that the unmanned aerial vehicle body 100 flies directly above a collection site. The unmanned aerial vehicle body 100 is controlled to descend through the wireless controller. When the unmanned aerial vehicle body 100 descends, the sound produced by the rotation of the rotors of the unmanned aerial vehicle body 100 and the airflow produced during the rotation of the rotors can be used to drive away the animals, so that the animals bred in the poultry house are scattered. The unmanned aerial vehicle body 100 falls to the collection site, meanwhile the supporting feet 200 are used to support the unmanned aerial vehicle body 100, and the sampling unit 300 is started through the wireless controller to collect fecal samples. The sampling power portion 320 is powered on to rotate, and the sampling power portion 320 drives the sampling shaft 312 to rotate. The sampling shaft 312 scoops up feces through the spiral blades, and feces are conveyed to an upper end of an interior of the sampling tube 311. After sampling, the unmanned aerial vehicle body 100 takes off and flies back to a starting point.
The long-distance sampling device for feces in a poultry house according to an embodiment of the present disclosure carries the sampling unit 300 for sampling through the unmanned aerial vehicle. The unmanned aerial vehicle can drive away the animals when landing. Meanwhile, after the unmanned aerial vehicle lands, the sampling unit 300 scrapes the samples. Since the spiral blades are arranged on the sampling shaft 312, the sampling unit 300 can not only take samples, but also temporarily store the samples. After sampling, the unmanned aerial vehicle body 100 flies back to the starting point, so that it is convenient for the workers to take samples in the poultry house, thereby the convenience of sampling is improve, and the workers do not need to get into the breeding areas.
Specifically, the unmanned aerial vehicle body 100 and the wireless controller belong to the prior art. The structure of the unmanned aerial vehicle body 100 is the same as that of the unmanned aerial vehicle body currently available in the market. The device in the present disclosure can be obtained by modifying the unmanned aerial vehicle body available in the market.
A multi-rotor unmanned aerial vehicle is provided as the unmanned aerial vehicle body 100. Blade protection covers 110 are arranged on the blades of the unmanned aerial vehicle body 100. The blade protection covers 110 are used for protecting the blades and also protecting the bred animals. Because the blades are in a state of high-speed rotation during operation, the blades may hurt the animals that have not been driven away after the unmanned aerial vehicle body 100 lands. Therefore, it is required to arrange the blade protection covers 110 around the blades, and the blade protection covers 110 are of a mesh structure.
It should be noted that when the rotors of the unmanned aerial vehicle body 100 can be folded, the blade protection covers 110 are detachably connected to the unmanned aerial vehicle body 100. Furthermore, the blade protection covers 110 each include a spherical surface, a mesh protection cover, a mounting seat, and mounting rods. The mounting seat is in a circular ring shape. The mounting rods are arranged on an inner wall of the mounting seat. Several mounting rods are provided. The mounting rods are radially arranged in the mounting seat. The axes of the mounting rods pass through a center of the mounting seat. The mounting rods are integrated with the mounting seat. A mounting sleeve fixed to the mounting rods is arranged at the center of the mounting seat. The mounting sleeve is sleeved on a motor for the rotors. The protection cover is sleeved on the mounting seat through an interference connection, so that the blade protection covers 110 are detachable.
As a preferred embodiment, in this embodiment, automatic telescopic supporting feet are provided as the supporting feet 200. In some examples, electronic telescopic rods are provided as the supporting feet 200, and the supporting feet 200 are fixedly connected to the rotors of the unmanned aerial vehicle body 100 through screws. During sampling, the length of the supporting feet 200 is gradually shortened, so that the distance between the unmanned aerial vehicle body 100 and the ground is gradually reduced, so that the sampling unit 300 can conduct sampling deeply into feces to collect enough samples, thus the number of times of sampling at the same position is reduced.
It should be noted that a foot pad 210 is arranged at an end, away from the unmanned aerial vehicle body 100, of each of the supporting feet 200. The foot pad 210 is in a conical shape and made of rubber. The foot pad 210 is sleeved on the end, away from the unmanned aerial vehicle body 100, of each of the supporting feet 200 to increase the contact area between the supporting feet 200 and the ground, thereby preventing the supporting feet 200 from sinking into the ground.
In this embodiment, the supporting feet 200 are extended after sampling is finished, which can pull the sampling unit 300 out of the feces, so that the resistance during takeoff is reduced.
It should be noted that the expansion and retraction of the supporting feet 200 are automatically controlled by a control chip in the unmanned aerial vehicle body 100, and the expansion and retraction speed is related to the rotational resistance of the sampling unit 300. The correlation between the expansion and retraction speed and the rotational resistance is obtained by calculations and experiments. When the rotational resistance of the sampling unit 300 is high, the retraction speed of the supporting foot 200 is slow, and when the rotational resistance of the sampling unit 300 is low, the retraction speed of the supporting foot 200 is fast, so that the sampling unit 300 can always scrape samples during operation.
As shown in
Preferably, a preset space is formed between ends, away from the opening of the sampling tube 311, of the spiral blades and a bottom of the sampling tube 311 for storing the samples. Predictably, the samples are solid, and when the sampling shaft 312 stops rotating, the samples in the sampling tube 311 will not roll off from the spiral blades under the action of friction between solids.
It should be noted that in this embodiment, the sampling operation of the sampling unit 300 can also be automatically carried out through a preset program, and the sampling power portion 320 is automatically started at a preset time after the landing of the unmanned aerial vehicle body 100, so that the sampling unit 300 automatically takes the samples.

As a preferred embodiment, in this embodiment, as shown in
In this embodiment, when the sampling portion 310 is required to be released, the clamping arms 410 are driven to rotate in a direction away from the sampling portion 310 through the clamping power portions 440, so that the clamping plates 420 are detached from the sampling portion 310. When the sampling portion 310 is required to be clamped, the clamping arms 410 are driven to rotate in a direction towards the sampling portion 310 through the clamping power portions 440 to clamp the sampling portion 310.
In this embodiment, the clamping plates 420 are hinged to an end, away from the unmanned aerial vehicle body 100, of the clamping arms 410. The clamping plates 420 are connected with the clamping arms 410 through pins and lugs. The clamping plates 420 are connected with the clamping arms 410 through frictional damping between the pins and the lugs. The clamping arms 410 are hinged to the unmanned aerial vehicle body 100 through clamping shafts 430. Connecting lugs are arranged on the unmanned aerial vehicle body 100. The clamping shafts 430 are rotatably connected to the connecting lugs. The clamping arms 410 are fixedly connected with the clamping shafts 430 through key shaft connections. The clamping power portions 440 drive the clamping shafts 430 to rotate so as to drive the clamping arms 410 to rotate.

The shaft seat is fixedly connected to the unmanned aerial vehicle body 100 through screws. The clamping motor 444 is fixedly connected to the unmanned aerial vehicle body 100 through screws. In case that the clamping motor 444 drives the clamping power shaft 442 to rotate through a belt structure, when the clamping motor 444 rotates, the clamping motor 444 drives the clamping power shaft 442 to rotate, and the clamping power shaft 442 drives the two worms 443 to rotate. The two worms 443 rotate in opposite directions, the clamping power shaft 442 drives the worm gears 441 to rotate in opposite directions through the worms 443, thus, the two worm gears 441 can be driven to clamp/release the sampling portion 310.
Preferably, a connecting sleeve 321 is arranged on an output shaft of the sampling power portion 320. A connector 313 is arranged on the sampling shaft 312.
