Description

Technical Field

[0001] This invention belongs to the field of animal sampling technology, and specifically relates to a sampling device for parasites on the surface of animals. Background Technology

[0002] In the fields of veterinary medicine, parasitology research, and animal health management, accurately obtaining samples of ectoparasites from animals is a crucial prerequisite for in-depth research into parasite characteristics, transmission patterns, pathogenic mechanisms, and the development of effective prevention and control strategies. However, existing methods and devices for sampling ectoparasites from animals have many shortcomings and are insufficient to meet the needs of scientific research and practical applications.

[0003] Traditional manual sampling methods, such as using tweezers or brushes to collect parasites directly from the animal's body surface, are not only cumbersome and inefficient, but also pose a significant risk of injury to the operator. This is especially true for aggressive, small, or agile animals, where close-range manual sampling carries considerable risk and makes it difficult to ensure comprehensive and accurate sampling, potentially leading to missed parasite samples and affecting the reliability of subsequent research results.

[0004] Some existing sampling devices are complex in structure, expensive, and require professional operation and maintenance, which limits their widespread application in grassroots veterinary stations, farms, and field research. Moreover, these devices often cannot achieve automatic collection and classification of parasites, and samples are easily contaminated during collection, reducing sample quality and usability. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a sampling device for ectoparasites on animals.

[0006] The technical solution of the present invention is: a sampling device for ectoparasites on animals, comprising:

[0007] The sampling box body is hollow inside and has movable doors at both ends;

[0008] Two pressure plates are respectively set on the inner sides of both ends of the sampling box body. Multiple springs are provided between the pressure plates and the bottom of the inner side of the sampling box body. The pressure plates are connected to the movable doors on the corresponding sides through a first linkage component, which is used to drive the movable doors to close when the pressure plates descend and drive the movable doors to open when the pressure plates rise.

[0009] The sampling assembly includes a pass ring disposed in the middle section inside the sampling box body and sampling comb teeth movably disposed inside the pass ring, used to scrape off parasites from the animal's body surface when the animal passes through the pass ring, and an output tube is provided at the lower end of the pass ring for outputting the scraped parasites.

[0010] A collection box is connected and installed below the output tube. The collection box has multiple circumferentially arranged collection cavities for collecting parasites output from the output tube. The collection box is connected to the pressing plate through a second linkage component, which is used to drive the collection box to rotate when the pressing plate descends, so that the multiple collection cavities are connected to the output tube in sequence.

[0011] The lure box, located on the lower inner side of the passage ring, is used to attract animals into the sampling box body.

[0012] Furthermore, each of the aforementioned active gates includes:

[0013] Two vertical shafts are respectively rotatably set on both sides of the port of the sampling box body;

[0014] Two door bodies are provided, with one door body fixedly connected to the side of each vertical axis. The two door bodies are arranged symmetrically and are used to open and close under the action of the vertical axis.

[0015] Two first bevel gears are provided, with one first bevel gear fixed coaxially at the lower end of each vertical shaft, and the bevel gears are connected to the first linkage assembly.

[0016] Furthermore, each of the first linkage components includes:

[0017] The first horizontal axis is rotatably set on the lower side of the port of the sampling box body;

[0018] Two second bevel gears are coaxially fixedly mounted on both ends of the first horizontal shaft, and the two second bevel gears mesh with the first bevel gears on the same side respectively;

[0019] Two first gears are coaxially fixedly mounted on both ends of the first horizontal shaft;

[0020] Two racks are vertically arranged on the side of the foot plate, and the two racks mesh with the first gear on the corresponding side.

[0021] Furthermore, the inner side of the ring is provided with multiple piston channels, each piston channel is provided with a sampling comb tooth, each piston channel outlet is fixedly provided with a limiting ring, the inner end of the sampling comb tooth is provided with a piston head, and the piston head is slidably disposed in the piston channel in a sealed manner.

[0022] Furthermore, each of the pressing plates is provided with an airbag below it. The upper end of the airbag is fixedly connected to the lower surface of the pressing plate, and the lower end of the airbag is fixedly connected to the bottom of the sampling box body. The middle part of the airbag is connected to the side of the passing ring through a pipe and communicates with multiple piston channels. It is used to pressurize the piston channels when the pressing plate descends, so that the sampling comb teeth extend. When the pressing plate rises, it depressurizes the piston channels, so that the sampling comb teeth retract and the parasites adhering between the sampling comb teeth are scraped off the limiting ring and slide down into the output pipe through the inner side of the passing ring.

[0023] Furthermore, the collection box includes:

[0024] A base is fixedly installed at the bottom of the sampling box body, and a central axis is vertically provided at the center of the base.

[0025] The box body is movably sleeved on the outside of the central axis, and the collection chambers are circumferentially arranged on the box body, with each collection chamber having an opening on its outer side;

[0026] A collection trough plate is movably inserted into each of the collection chambers;

[0027] A conical toothed ring is fixedly sleeved on the lower outer side of the box body;

[0028] A cover plate is fixedly installed at the top of the central shaft. The cover plate has a collection port that communicates with any collection chamber. The collection port is fixedly connected to the output pipe.

[0029] Furthermore, the second linkage component includes:

[0030] The second horizontal axis is symmetrically arranged on both sides of the pressing plate with respect to the first horizontal axis;

[0031] Two second gears are coaxially fixedly mounted on both ends of the second horizontal shaft;

[0032] Two ratchet pawls are respectively disposed on the side of the pressing plate, and the two ratchet pawls respectively mesh with the second gear on the corresponding side, for driving the second gear to rotate when the pressing plate descends;

[0033] The third bevel gear is coaxially fixed in the middle of the second horizontal shaft;

[0034] The fourth bevel gear is rotatably disposed at the bottom of the sampling box body. One side of the fourth bevel gear meshes with the third bevel gear, and the other side of the fourth bevel gear meshes with the bevel gear ring.

[0035] Furthermore, a bell is hung on the movable door to ring when the door is opened and closed, scaring animals away so they can escape through the other opening.

[0036] The working method of this invention is as follows: An attractant is placed in the attractant box to attract animals. Taking a mouse as an example, the mouse enters from any end of the sampling box body under the attraction of the attractant. After entering, the mouse steps on the pressure plate. Under the force of its weight, the pressure plate descends, and the movable door is closed by the first linkage component, preventing the mouse from escaping through the same route. At the same time, the collection box body is rotated by the second linkage component, so that multiple collection chambers are connected to the output pipe in sequence. The air bladder is compressed by the pressure plate, and the gas in the air bladder is squeezed into the piston channel of the through ring, causing the sampling comb teeth to extend. When the movable door closes, it pulls... The bell rings, startling the mice, which then escape from the other end. As they escape, the mice crawl through the passage ring, and the sampling combs scrape off the parasites from their bodies. After the mice escape, the pressure plate rises and resets under the action of the spring, opening the movable door and causing the airbag to return to its original position. This extracts the gas from the piston channel, causing the sampling combs to retract. The parasites adhering between the sampling combs are scraped off the limiting ring, slide down the inside of the passage ring, and then slide through the output tube into the collection chamber of the sampling box. During the rising process, the pressure plate does not rotate the box due to the action of the ratchet pawl. The above steps are repeated to collect the parasites from multiple mice.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] This invention uses an attractant box to release attractants, drawing animals into the sampling box body and increasing the probability of animals entering the device, making sampling easier. Once inside, the animal presses a pressure plate, automatically closing the movable door to prevent escape and ensuring the animal follows a pre-set route through the loop, increasing the chance of parasites being scraped off. As the pressure plate descends, it rotates the collection box, with multiple collection chambers sequentially connecting to the output pipe, enabling the classified collection of parasites from different animals for subsequent research and analysis. The coordination of the air bladder and sampling comb teeth controls the extension and retraction of the comb teeth at different stages of animal entry and escape, efficiently scraping off parasites and causing them to fall into the collection box, improving sampling efficiency.

[0039] The collection box of this invention features a circumferentially arranged collection chamber with an outer opening, which, together with a movable collection slot plate, facilitates the removal and storage of samples and avoids cross-contamination between different samples. Each collection chamber is independent, ensuring that each sample remains intact and pure, which is beneficial for accurate analysis of parasite species, quantity, and other characteristics.

[0040] This invention utilizes the animal's own gravity and mechanical linkage components to achieve automatic sampling and collection operations, eliminating the need for complex manual intervention and electronic component control, thus reducing operational difficulty and labor intensity. Furthermore, it does not involve complex circuit connections, further reducing usage and maintenance costs.

[0041] This invention is applicable to the sampling of various animal ectoparasites. For example, it can be extended to other common animals that carry parasites, providing a universal sampling tool for animal disease research, parasite control, and other fields, and helping to carry out relevant scientific research and formulate practical prevention and control measures.

[0055] The sampling box body 1 is hollow inside, and has movable doors 11 at both ends, such as... Figure 2-3 As shown, each movable door 11 includes a vertical shaft 111, a door body 112, and a first bevel gear 113; two vertical shafts 111 are respectively rotatably arranged on both sides of the port of the sampling box body 1; a door body 112 is fixedly connected to the side of each vertical shaft 111, and the two door bodies 112 are symmetrically arranged for opening and closing under the drive of the vertical shaft 111; a first bevel gear 113 is coaxially fixed at the lower end of each vertical shaft 111, and the first bevel gear 113 is connected to the first linkage component 22; a bell 114 is hung on the movable door 11 for ringing when the door body 112 is opened and closed, scaring the animal to escape from the other opening;

[0056] Two pressure plates 2 are respectively installed on the inner sides of both ends of the sampling box body 1.

The middle part of the airbag 23 is connected to the side of the passing ring 31 through a pipe and communicates with multiple piston channels 311. It is used to pressurize the piston channel 311 when the pressing plate 2 descends, so that the sampling comb teeth 32 extend. When the pressing plate 2 rises, the piston channel 311 is depressurized by evacuating air, so that the sampling comb teeth 32 retract and the parasites adhering between the sampling comb teeth 32 are scraped off on the limiting ring 312 and slide down into the output pipe 33 through the inside of the passing ring 31.

[0058] Collection box 4 is connected and positioned below output tube 33, such as Figure 9As shown, the collection box 4 has multiple circumferentially arranged collection cavities 41 for collecting parasites output from the output tube 33. The collection box 4 is connected to the pressing plate 2 via a second linkage component 42, which rotates the collection box 4 when the pressing plate 2 descends, so that the multiple collection cavities 41 are sequentially connected to the output tube 33. The collection box 4 includes a base 43, a box body 45, a collection groove plate 46, a conical tooth ring 47, and a cover plate 48. The base 43 is fixedly installed at the bottom of the sampling box body 1, and a central shaft 44 is vertically provided at the center of the base 43. The box body 45 is movably sleeved on the outside of the central shaft 44, and the collection cavities 41 are circumferentially arranged on the box body 45, with each collection cavity 41 having an opening on its outer side. A collection groove plate 46 is movably inserted into each collection cavity 41. The conical tooth ring 47 is fixedly sleeved on the lower part of the outer side of the box body 45. The cover plate 48 is fixedly installed at the top of the central shaft 44, and the cover plate 48 has a connection point for each collection cavity. The cavity 41 is connected to the collection port, which is fixedly connected to the output pipe 33. The second linkage component 42 includes a second horizontal shaft 421, a second gear 422, a ratchet pawl 423, a third bevel gear 424, and a fourth bevel gear 425. The second horizontal shaft 421 is symmetrically arranged on both sides of the pressing plate 2 with the first horizontal shaft 221. The two second gears 422 are coaxially fixedly arranged on both ends of the second horizontal shaft 421. The two ratchet pawls 423 are respectively arranged on the side of the pressing plate 2, and the two ratchet pawls 423 respectively mesh with the second gear 422 on the corresponding side, which is used to drive the second gear 422 to rotate when the pressing plate 2 descends. The third bevel gear 424 is coaxially fixedly arranged in the middle of the second horizontal shaft 421. The fourth bevel gear 425 is rotatably arranged in the bottom of the sampling box body 1. One side of the fourth bevel gear 425 meshes with the third bevel gear 424, and the other side of the fourth bevel gear 425 meshes with the bevel ring 47.

[0059] The lure box 5 is located on the lower inner side of the passage ring 31 and is used to attract animals into the sampling box body 1.

[0060] The working method of the above embodiment is as follows: An attractant is placed in the attractant box 5 to attract animals. Taking a mouse as an example, the mouse, attracted by the attractant, enters from any end of the sampling box body 1. After entering, the mouse steps on the pressure plate 2. Under the force of its own weight, the pressure plate 2 descends, causing the movable door 11 to close via the first linkage component 22, preventing the mouse from escaping along the same route. Simultaneously, the second linkage component 42 causes the box body 45 of the collection box 4 to rotate, so that multiple collection chambers 41 are connected to the output pipe 33 in sequence. Furthermore, the airbag 23 is compressed by the pressure plate 2, and the gas inside the airbag 23 is squeezed into the piston channel 311 through the ring 31, causing the sampling comb teeth 32 to extend. When the movable door 11 closes, it triggers a bell. A clanging sound (114) startles the rat, causing it to escape from the other end. As it escapes, the rat crawls through the passage ring 31, and the sampling comb teeth 32 scrape off the parasites from its body. After the rat escapes, the pressure plate 2 rises and resets under the action of the spring 21, opening the movable door 11 and causing the airbag 23 to return to its original position, extracting the gas from the piston channel 311. This causes the sampling comb teeth 32 to retract, and the parasites adhering between the sampling comb teeth 32 are scraped off the limiting ring 312, slide down the inside of the passage ring 31, and slide down the output tube 33 into the collection chamber 41 of the sampling box 4. During the rising process, the pressure plate 2 does not rotate the box body 45 due to the action of the ratchet pawl 423. The above steps are repeated to collect the parasites from the body of multiple rats.

[0061] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the protection scope of the present invention.
