Description

Technical Field

[0001] The present invention relates to the technical field of wild animal sampling, and in particular to a non-destructive sampling device for wild animals. Background Art

[0002] As wildlife conservation and research continue to deepen, traditional invasive sampling methods are increasingly being restricted and scrutinized due to potential harm to wildlife, impacts on their survival and behavior, and even disruptions to population ecology. To balance the needs of scientific research and monitoring with animal welfare, non-invasive wildlife sampling devices have emerged. These devices are designed to efficiently and accurately collect non-invasive samples such as hair, feces, and shed cells from wildlife, minimizing disruption to wildlife and generating reliable data to support species conservation, ecological research, and disease monitoring.

[0003] Although some existing non-destructive sampling devices for wild animals can collect samples from wild animals to a certain extent, they may disturb the wild animals when collecting samples, and there is a problem of low collection efficiency.

[0004] In summary, some existing non-destructive sampling devices for wild animals may disturb wild animals when collecting samples. The problem of low collection efficiency has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a non-destructive sampling device for wild animals. Summary of the Invention

[0005] To solve the above problems, the present invention provides a non-destructive sampling device for wild animals. By combining an aroma diffusion component, a feeding component, a hair collection component and a feces collection component into one, the sampling device can effectively attract wild animals to approach through food, and collect the hair and feces of wild animals at the same time through the hair collection component and the feces collection component, thereby improving the efficiency of collecting biological samples of wild animals.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a non-destructive sampling device for wild animals, including a controller and a sampling rack, the bottom wall of the sampling rack is fixedly connected to a feeding frame, the top wall of the sampling rack is provided with an aroma diffusion component for diffusing the aroma of food to the outside world, and a feeding component for regularly lowering food into the feeding frame.

[0007] The sampling rack is also equipped with a hair collection component for collecting hair of wild animals, and a driving component for driving the hair collection component, aroma diffusion component and feeding component to operate together; a feces collection component for collecting feces of wild animals is provided on one side of the feeding frame, and the feces collection component is located below the hair collection component.

[0008] The technical principles of the above scheme are as follows:

[0009] Staff install the non-invasive wildlife sampling device at a predetermined location. A controller controls the drive assembly, which drives the hair collection assembly, aroma diffusion assembly, and feeding assembly. The feeding assembly drops food in batches at regular intervals, while the aroma diffusion assembly diffuses the food's aroma. Simultaneously, the hair collection assembly collects the wildlife's hair. When a wildlife defecates within the sampling device, the feces collection assembly collects the feces.

[0010] The above scheme has the following beneficial effects:

[0011] 1. The present invention combines an aroma diffusion component, a feeding component, a hair collection component, and a feces collection component into one, so that the sampling device can effectively attract wild animals to approach through food, and collect the hair and feces of wild animals simultaneously through the hair collection component and the feces collection component, thereby improving the efficiency of collecting biological samples from wild animals.

[0012] 2. The present invention releases food into the feeding frame through the feeding component, so that the sampling device can attract wild animals through the aroma of the food, and diffuse the aroma of the food under the synergistic effect of the aroma diffusion component, thereby expanding the range of attraction to wild animals.

[0013] 3. The present invention collects the hair and feces of wild animals in a non-disturbing manner through the hair collection component and the feces collection component, thereby improving the collection efficiency and reducing the stress response of wild animals.

[0014] Furthermore, the driving assembly includes fixed columns symmetrically fixedly connected to the inner top wall of the sampling rack, and a first fixed frame and a second fixed frame are fixedly connected between adjacent fixed columns from top to bottom in sequence, a fixed plate is fixedly connected to one side of the second fixed frame, a tooth plate is hinged on the first fixed frame, and a driving member is fixedly connected to the top of the fixed plate, and the controller is used to control the rotation of the output shaft of the driving member.

[0015] A driving plate is fixedly connected to the output shaft of the driving member. The side of the driving plate away from the output shaft of the driving member is fixedly connected to the driving shaft. One side of the gear plate is fixedly connected to the driving frame. The driving shaft is located in the driving frame and slides with the driving frame.

[0016] Beneficial effects: The fixed column, the first fixing frame and the second fixing frame form a stable internal support structure. By installing the driving member on the fixing plate, the operating stability of the sampling device is ensured, making it suitable for complex field environments.

[0017] Furthermore, the feeding assembly includes a feeding box fixedly connected to the top wall of the sampling rack, the feeding box is filled with food, a feeding plate is vertically slidably fitted in the feeding box, a feeding rod is hinged at the bottom of the feeding plate, and the feeding rod is hinged to the tooth plate at one end away from the feeding plate; a feeding tube is connected to the upper side wall of the feeding box, and the feeding tube is connected to the feeding frame.

[0018] Beneficial Effects: The design of feeding food into the feeding frame through the feeding tube prevents food from being directly exposed to the external environment and contamination. Furthermore, by periodically releasing food to attract wildlife to the sampling area, the probability of collecting hair and fecal samples from wildlife can be effectively increased, enhancing the continuity and effectiveness of data acquisition.

[0019] Furthermore, the aroma diffusion component includes a diffusion box fixedly connected to the inner top wall of the sampling rack, the inner side wall of the diffusion box is vertically slidably fitted with a diffusion plate, the bottom of the diffusion plate is hinged with a diffusion rod, the diffusion rod is hinged to the tooth plate at one end away from the diffusion plate, and the side wall of the diffusion box is connected to an air inlet one-way valve and an air outlet one-way valve.

[0020] Beneficial effects: The diffusion plate in the diffusion box can be linked with the tooth plate through the diffusion rod, so that it can move up and down periodically under the control of the driving component, thereby intermittently changing the volume of the internal space of the diffusion box, so that the aroma of the food can be diffused in a timed and controllable manner, thereby enhancing its attractiveness to wild animals.

[0021] Furthermore, the hair collection assembly includes a rotating rod rotatably engaged with the second fixed frame, the rotating rod is fixedly connected to a gear, the gear is engaged with the tooth plate, the rotating rod is also fixedly connected to a hair collection rod, and the hair collection rod is fixedly connected to a hair collection block.

[0022] An elastic plate is hinged on the inner side wall of the sampling rack, and the elastic plate is located in the movement path of the hair collecting block; a hair collecting frame is fixedly connected to the inner bottom wall of the sampling rack, and the hair collecting frame is located just below the elastic plate.

[0023] Beneficial effect: When the rotating rod rotates, it drives the hair collecting rod to rotate, so that the hair collecting block fixed on it moves periodically in the sampling area, collecting and sampling the shed hair on the surface of wild animals, which improves the collection efficiency and reduces the disturbance to wild animals.

[0024] Furthermore, the feces collection assembly includes a feces collection frame fixedly connected to the inner bottom wall of the sampling frame, a feces collection net is detachably connected to the top of the feces collection frame, and one side of the feces collection frame is fixedly connected to the outer wall of the feeding frame.

[0025] Beneficial effects: The preliminary screening of the feces collection net can effectively prevent larger impurities from entering the feces collection frame, thereby ensuring that the collected feces samples are relatively pure, which is helpful for subsequent analysis operations.

[0026] Furthermore, a camera is symmetrically fixedly connected to the sampling rack, and the controller is electrically connected to the cloud processor. The controller is used to collect image information collected by the camera and send the image information to the cloud processor. The cloud processor analyzes the image information to determine whether the wild animal in the image information is a wild animal that needs to be sampled, and sends the judgment result to the controller. The controller controls the rotation of the output shaft of the drive member according to the judgment result.

[0027] Beneficial effects: By identifying target animals and dynamically controlling the sampling process, behavioral interference with non-target species is reduced, while also reducing the energy consumption of the device.

[0028] Furthermore, a silicone collection layer is fixedly connected to the hair collection block.

[0029] Beneficial effects: Due to its unique softness and adhesion, silicone material can effectively pick up hair from wild animals. Compared with hard materials, it increases the friction and adsorption capacity when in contact with animal fur, thereby improving the efficiency of hair collection.

[0030] Furthermore, the diffusion rod and the feeding rod are both arc-shaped.

[0031] Beneficial effects: The arc-shaped design of the diffusion rod and the feeding rod enables them to better match the motion trajectory of the tooth plate, making the force transmission more uniform and smooth, thereby improving the transmission efficiency and stability of the sampling device.

[0032] Furthermore, a food feeding port is provided on the feeding box.

[0033] Beneficial Effects: The food inlet provides a convenient and quick way to add food to the feeding box without having to disassemble or open the entire feeding box, thereby simplifying the operating process.

[0034] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Example 1:

[0043] As attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown: A non-destructive sampling device for wild animals, including a controller and a sampling rack 1, a feeding frame 2 is integrally formed on the inner bottom wall of the sampling rack 1, and a driving component is provided in the sampling rack 1.

[0044] The drive assembly includes fixed columns 3 symmetrically welded to the inner top wall of the sampling rack 1. A first fixed frame 4 and a second fixed frame 5 are integrally formed between adjacent fixed columns 3 from top to bottom. A fixed plate 6 is integrally formed on one side of the second fixed frame 5. A tooth plate 7 is hinged on the first fixed frame 4. A drive member is fixedly connected to the top of the fixed plate 6 by bolts. A controller is used to control the rotation of the output shaft of the drive member. A drive plate 8 is bolted to the output shaft of the drive member. A drive shaft 9 is integrally formed on the side of the drive plate 8 away from the output shaft of the drive member. A drive frame 10 is welded to one side of the tooth plate 7. The drive shaft 9 is located inside the drive frame 10 and slides with the drive frame 10. In this embodiment, the drive member uses a stepper motor.

[0045] Specifically, because the drive plate 8 is fixedly connected to the stepper motor output shaft by bolts, and the drive shaft 9 is integrally formed with the drive plate 8, when the stepper motor output shaft rotates, it can drive the drive plate 8 and the drive shaft 9 to rotate with it. Furthermore, because the drive shaft 9 is in sliding engagement with the drive frame 10, and the drive frame 10 is welded to the gear plate 7, when the drive shaft 9 rotates, it can drive the drive frame 10 and the gear plate 7 to swing back and forth.

[0046] The inner top wall of the sampling rack 1 is provided with an aroma diffusion component for diffusing the aroma of food to the outside, and a feeding component for regularly placing food into the feeding frame 2.

[0047] The feeding assembly includes a feeding box 11 welded to the inner top wall of the sampling rack 1. The feeding box 11 has a food inlet (not shown) and is filled with food. A feeding plate 12 is vertically slidably fitted within the feeding box 11. An arc-shaped feeding rod 13 is hingedly connected to the bottom of the feeding plate 12. The end of the feeding rod 13, away from the feeding plate 12, is hingedly connected to the tooth plate 7. A feeding cylinder 14 is connected to the upper side wall of the feeding box 11 and is connected to the feeding frame 2. In this embodiment, the food itself has an aroma.

[0048] Specifically, since the feeding rod 13 is hinged to the tooth plate 7, when the tooth plate 7 swings, it can drive the feeding rod 13 to swing with it, and the feeding rod 13 drives the feeding plate 12 to slide vertically back and forth in the feeding box 11, thereby lifting the food. When the food is lifted to the feeding cylinder 14, the food can fall into the feeding frame 2 through the feeding cylinder 14, thereby lowering the food.

[0049] The aroma diffusion assembly includes a diffusion box 15 welded to the inner top wall of the sampling rack 1, and a diffusion plate 16 is vertically slidably fitted on the inner wall of the diffusion box 15. An arc-shaped diffusion rod 17 is hinged at the bottom of the diffusion plate 16, and the diffusion rod 17 is hinged to the tooth plate 7 at one end away from the diffusion plate 16. An air inlet check valve 18 and an air outlet check valve 19 are connected to the side wall of the diffusion box 15.

[0050] Specifically, since the diffusion rod 17 is hinged to the tooth plate 7, when the tooth plate 7 swings, it can drive the diffusion rod 17 to swing with it, and drive the diffusion plate 16 to slide vertically back and forth in the diffusion box 15 through the diffusion rod 17. At this time, the gas in the diffusion box 15 is released into the sampling rack 1 through the exhaust one-way valve 19, causing it to disturb the food inside the feeding frame 2, diffusing the aroma of the food to the outside world, and attracting wild animals.

[0051] The sampling rack 1 is also provided with a hair collecting component for collecting hair of wild animals.

[0052] The hair collection assembly includes a rotating rod 20 that is rotatably engaged with the second fixed frame 5. A gear 21 is fixedly clamped on the rotating rod 20, and the gear 21 is engaged with the tooth plate 7. A hair collection rod 22 is also integrally formed on the rotating rod 20, and a hair collection block 23 is integrally formed on the hair collection rod 22. A silicone collection layer is bonded to the hair collection block 23.

[0053] An elastic plate 24 is hinged on the inner wall of the sampling rack 1 , and the elastic plate 24 is located in the movement path of the hair collecting block 23 ; a hair collecting frame 25 is integrally formed on the inner bottom wall of the sampling rack 1 , and the hair collecting frame 25 is located directly below the elastic plate 24 .

[0054] Specifically, since the gear 21 is meshed with the toothed plate 7, when the toothed plate 7 swings back and forth, it can drive the gear 21 to rotate back and forth. Furthermore, since the gear 21 is fixedly engaged with the rotating rod 20, and the rotating rod 20 and the hair collecting rod 22 are integrally formed, when the gear 21 rotates, it can drive the rotating rod 20 and the hair collecting rod 22 to rotate together with it, and the hair collecting rod 22 drives the hair collecting block 23 to rotate, thereby collecting hair from the surface of the wild animal.

[0055] At the same time, since the elastic plate 24 is located in the movement path of the hair collecting block 23, the hair collecting rod 22 will also contact the elastic plate 24 during the rotation process, and under the action of the elastic plate 24, the collected hair will be shaken into the hair collecting frame 25, completing the hair collection.

[0056] A feces collecting component for collecting feces of wild animals is provided on one side of the feeding frame 2, and the feces collecting component is located below the hair collecting component.

[0057] The feces collection assembly includes a feces collection frame 26 integrally formed on the inner bottom wall of the sampling frame 1. The top of the feces collection frame 26 is detachably connected to a feces collection net 27 by bolts. One side of the feces collection frame 26 is integrally formed with the outer side wall of the feeding frame 2.

[0058] Specifically, since the feces collection frame 26 is located inside the sampling rack 1, when wild animals defecate inside the sampling rack 1, their feces can pass through the feces collection net 27 and enter the feces collection frame 26. During this process, the feces collection net 27 will block large-diameter impurities from the outside of the feces collection frame 26 to ensure its purity.

[0059] The specific implementation process is as follows: the staff installs the sampling device at the predetermined position, and then controls the stepper motor output shaft to rotate through the controller, so that it drives the drive shaft 9 and the drive plate 8 to rotate, and the drive shaft 9 drives the drive frame 10 and the gear plate 7 to swing back and forth.

[0060] As the toothed plate 7 swings, it causes the feeding rod 13 and the diffusion rod 17 to swing, respectively, which in turn drives the feeding plate 12 and the diffusion rod 17 to slide back and forth vertically. The food is periodically lifted by the feeding plate 12 and periodically lowered into the feeding frame 2 by the feeding cylinder 14. The air in the diffusion box 15 is discharged through the diffuser plate 16 through the exhaust check valve 19, diffusing the food's aroma and attracting wild animals.

[0061] During the swinging process, the tooth plate 7 also drives the gear 21 to rotate, and the gear 21 drives the rotating rod 20 and the hair collecting rod 22 to rotate. The hair collecting rod 22 drives the hair collecting block 23 to rotate, collecting the hair on the surface of the wild animal, and under the action of the elastic plate 24, the hair is shaken off into the hair collecting frame 25, completing the collection of the wild animal hair.

[0062] When wild animals defecate on the feces collection net 27, their feces will pass through the feces collection net 27 into the feces collection frame 26, completing the collection of the feces.

[0063] The present invention combines an aroma diffusion component, a feeding component, a hair collection component and a feces collection component into one, so that the sampling device can effectively attract wild animals to approach through food, and collect the hair and feces of wild animals at the same time through the hair collection component and the feces collection component, thereby improving the efficiency of collecting biological samples of wild animals.

[0064] Example 2:

[0065] As attached Figure 1 and Figure 2 As shown, the difference from Example 1 is that a camera 28 is fixedly connected to the sampling frame 1 by symmetrical screws, and the controller is electrically connected to the cloud processor. The controller is used to collect image information collected by the camera 28, and send the image information to the cloud processor. The cloud processor analyzes the image information, determines whether the wild animal in the image information is a wild animal that needs to be sampled, and sends the judgment result to the controller, which controls the rotation of the output shaft of the stepper motor according to the judgment result.

[0066] The specific implementation process is as follows: Camera 28 captures the current environment image in real time and sends it to a cloud-based processor for analysis. The cloud-based processor then determines the wildlife species in the image. When a wildlife species for sample collection appears in the environment, the controller controls the stepper motor output shaft to rotate, activating the collection device, attracting the wildlife to approach and collecting hair and feces.

[0067] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
