Description

Technical Field

[0001] The invention relates to the technical field of sampling and detection, in particular to a sampling and detection device for animal husbandry and veterinary medicine. Background Art

[0002] As an important branch of agriculture, animal husbandry is not only related to human food supply, but also closely related to economic development, ecological environment and public health safety. It uses domesticated livestock and poultry and some wild animals. Animal husbandry converts plant energy such as grass and feed into animal energy through artificial breeding and reproduction. This conversion process is not only efficient, but also provides a rich source of nutrition for humans. Animal products such as meat, eggs and milk are an important part of human daily diet, providing essential nutrients such as protein, fat, vitamins and minerals. At the same time, by-products such as wool, cashmere and hides also play an important role in the fields of textiles and clothing.

[0003] In animal husbandry, animals are often threatened by diseases. To prevent the spread of diseases, animal husbandry workers need to regularly take samples and test animal excrement, so that they can use the biological information in the excrement to reflect the health status of animals and help to promptly detect and treat potential diseases. Through scientific sampling and laboratory analysis, they can accurately assess animal health and formulate targeted feeding management and disease prevention and control measures.

[0004] When it is necessary to test the health of an animal, the most common method is to take samples of its feces using a swab.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0032] In this embodiment, during the livestock breeding process, it is necessary to regularly test the physical health of the livestock. Fecal samples are one of the commonly used sample types in veterinary examinations. By testing fecal samples, the digestive status, nutrient absorption, parasitic infection, and the incidence of certain diseases of the animals can be understood. First, the device is manually held to align with the sampling location, and then the push plate 20 is manually pressed. Then the push plate 20 drives the push rod 2 to move, and then the push rod 2 drives the sliding plate 301 to slide along the inner wall of the housing 1. The top of the sliding plate 301 is fixedly connected with a first tension spring 13. The end of the first tension spring 13 away from the sliding plate 301 is fixedly connected to the top of the inner wall of the shell 1, and the first tension spring 13 will be stretched. When the sliding plate 301 slides, the sliding tube 303 will be driven to move synchronously through the fixed rod 302. During the movement of the sliding tube 303, its end will slide downward along the inside of the inclined groove 305, so that the sealing box 304 will be squeezed by the inclined groove 305, and then it will slide horizontally outward along the outer wall of the shell 1, so that the two sealing boxes 304 are away from the bottom of the storage box 4 and no longer protected, so that the swab 19 is facing the bottom of the storage box 4. At the sampling point, the outer wall of the swab 19 is slidably connected to the inner wall of the storage cavity 16, and the outer wall of the push rod 306 is slidably connected to the inner wall of the ring 17, and the bottom of the push rod 306 corresponds to the top of the swab 19. When the sliding plate 301 slides downward, the push rod 306 will be driven to move downward synchronously, and then the bottom of the push rod 306 will move to the inside of the storage cavity 16, and then the top of the swab 19 will be squeezed to make the swab 19 slide downward along the inner wall of the storage cavity 16. At the same time, the second tension spring 18 will be stretched, so that the bottom of the swab 19 will contact the feces and take samples, and then When sampling is completed, the pressure on the push plate 20 is released, and then the sliding plate 301 is reset by the tension of the first tension spring 13, so that it will slide upward along the inner wall of the shell 1, so that the push rod 306 no longer squeezes the swab 19, so that the swab 19 is reset by the tension of the second tension spring 18 and slides back into the storage chamber 16. At the same time, the end of the sliding tube 303 is driven by the sliding plate 301 to slide upward along the inner wall of the inclined groove 305, so that the two sealing boxes 304 slide together, thereby re-sealing the bottom of the storage box 4 to protect the sampled sample.

[0033] As described above, after the sampling is completed, the push plate 20 is released to drive the sliding plate 301 to slide upward, so that the end of the sliding tube 303 slides upward along the inner wall of the inclined groove 305, and the two sealing boxes 304 are slid together, thereby effectively sealing and protecting the bottom of the storage box 4, so that the sample can be sealed immediately, reducing the contact time between the sample and the external environment, thereby reducing the risk of environmental contamination, and also ensuring the integrity of the sample in the swab 19 for subsequent testing.

[0034] Embodiment 2: Based on the above embodiment, a transmission mechanism 5 is fixedly provided on the top of the storage box 4.

[0035] Further, the transmission mechanism 5 includes a fixed column 501, and the outer wall of the fixed column 501 is provided with a slot 502, the inner wall of the slot 502 is fixedly installed with a pawl 503, the outer wall of the pawl 503 is matched and meshed with a ratchet 504, the top of the fixed column 501 is provided with a slot 505, the inner wall of the sealing box 304 is fixedly connected to the slide bar 14, and the outer wall of the slide bar 14 is provided with a tooth groove 15, the inner wall of the tooth groove 15 is matched and meshed with the outer wall of the ratchet 504 ... matched and meshed with the outer wall of the ratchet 504. The outer wall is provided with a tooth groove 15, the inner wall of the tooth groove 15 matches and meshes with the outer wall of the ratchet wheel 504 teeth, the top of the connecting plate 7 is fixedly connected to the limiting rod 9, and the outer wall of the limiting rod 9 passes through and is slidably connected to the inside of the sliding plate 301, the inside of the limiting rod 9 is fixedly connected to a second spring 10, and the end of the second spring 10 away from the limiting rod 9 is fixed with a push plate 11, the side wall of the push plate 11 is slidably connected to the inner wall of the limiting rod 9, the inner top of the outer shell 1 is fixedly connected to a slide cylinder 12, and the outer wall of the limiting rod 9 is slidably connected to the inner wall of the slide cylinder 12.

[0036] In this embodiment, during the sampling process, the sliding plate 301 drives the connecting plate 7 and the protrusion 8 to move downward synchronously through the first spring 6, and the outer wall of the protrusion 8 corresponds to the inner wall of the slot 505. When the protrusion 8 moves down to a certain distance, the outer wall of the protrusion 8 will slide to the inner wall of the slot 505, thereby limiting the rotation of the fixed column 501 to prevent the swab 19 from deviating during the sampling process. Then, during the downward movement of the sliding plate 301, the first spring 6 will be compressed, and then the connecting plate 7 will drive the limiting rod 9 to stop moving, and then the sliding plate 301 will move along the limiting rod 9. 505, and the second spring 10 is driven by the connecting plate 7 to move the second spring 10 away from the inner wall of the card slot 505, and the second spring 10 is driven by the connecting plate 7 to move the second spring 10 away from the inner wall of the card slot 505, and the rotation limit of the fixing column 501 is cancelled. The sealing box 304 is reset to its original position through the sliding plate 301, and then the sealing box 304 drives the sliding rod 14 to move. During the movement of the sliding rod 14, the ratchet 504 is driven to rotate through the tooth groove 15, and then the ratchet 504 drives the fixed column 501 to rotate synchronously through the pawl 503. The bottom of the fixed column 501 is fixedly connected to the top of the storage box 4, and the bottom of the ratchet 504 is rotatably connected to the top of the storage box 4, so that the fixed column 501 drives the storage box 4 to rotate as a whole, so that the swab 19 corresponding to the stop rod 306 no longer corresponds to it. At the same time, the new swab 19 is rotated to a position corresponding to the bottom of the push rod 306, and the sliding plate 301 is reset. The sliding plate 301 will drive the limiting rod 9 to slide into the interior of the slide tube 12 through the second spring 10, and then the inner wall of the slide tube 12 will squeeze the top inclined surface of the second spring 10, and then the second spring 10 will slide into the interior of the limiting rod 9, and then the connecting plate 7 will be driven by the elastic force of the first spring 6 to drive the limiting rod 9 to slide downward to complete the reset. Since the storage box 4 rotates to make the new swab 19 correspond to the push rod 306, the next sampling work can be carried out directly.

[0037] As described above, after the sampling is completed, the sealing box 304 is reset by the sliding plate 301, and then the sealing box 304 drives the sliding rod 14 to move, so that the tooth groove 15 drives the ratchet 504 to rotate, and then the ratchet 504 will drive the storage box 4 to rotate as a whole through the fixed column 501, so that the new swab 19 is rotated to the position corresponding to the bottom of the push rod 306, and then the next sampling work can be carried out directly, so that after the sampling is completed, the next sampling preparation can be automatically adjusted without manual intervention or waiting time, which effectively improves the efficiency of the sampling work.

[0038] Working principle: In the process of animal husbandry, it is necessary to regularly check the physical health of the livestock. Fecal samples are one of the commonly used sample types in veterinary inspections. By testing fecal samples, we can understand the digestive status, nutrient absorption, parasitic infection, and the incidence of certain diseases of animals. First, manually hold the device and aim it at the sampling point. When the push plate 20 is manually pressed, the force will be immediately transmitted to the push rod 2 connected to the push plate 20. The push rod 2 can convert the pressing force into a moving force, and push the sliding plate 301 along a predetermined path, so that the sliding plate 301 slides smoothly on the inner wall of the outer shell 1. Therefore, as the push rod 2 is pushed, the sliding plate 301 slides smoothly on the inner wall of the outer shell 1. The movable plate 301 starts to slide stably along the inner wall of the shell 1. Since the sliding plate 301 is fixedly connected to one end of the first tension spring 13, and the other end of the first tension spring 13 is firmly fixed to the top of the inner wall of the shell 1, when the sliding plate 301 starts to slide, the first tension spring 13 will be gradually stretched, and then the stretching force ensures that the sliding plate 301 can stably return to the initial position when no external force is applied later. During the movement of the sliding tube 303, its end will slide downward along the inside of the inclined groove 305, so that the sealing box 304 will be squeezed by the inclined groove 305, and then it will slide horizontally outward along the outer wall of the shell 1. , so that the two sealing boxes 304 are away from the bottom of the storage box 4 and no longer protected, so that the swab 19 is facing the sampling position, the outer wall of the swab 19 is slidably connected to the inner wall of the storage cavity 16, the outer wall of the push rod 306 is slidably connected to the inner wall of the ring 17, and the bottom of the push rod 306 corresponds to the top of the swab 19. When the sliding plate 301 slides downward, the push rod 306 will be driven to move downward synchronously, and then the bottom of the push rod 306 will move to the inside of the storage cavity 16, and then the top of the swab 19 will be squeezed, so that the swab 19 slides downward along the inner wall of the storage cavity 16, and the second tension spring 18 will be stretched, so that the swab 19 The bottom of the swab 19 contacts the feces and samples. After that, when the sampling is completed, the push plate 20 is released, and then the sliding plate 301 is reset by the tension of the first tension spring 13, so that it slides upward along the inner wall of the shell 1, so that the push rod 306 no longer squeezes the swab 19, so that the swab 19 is reset by the tension of the second tension spring 18 and slides back into the storage chamber 16. At the same time, the end of the sliding tube 303 is driven by the sliding plate 301 to slide upward along the inner wall of the inclined groove 305, so that the two sealing boxes 304 slide together, so as to re-seal and protect the bottom of the storage box 4, which can protect the sampled sample;

[0039] After the sampling is completed, the push plate 20 is released to drive the sliding plate 301 to slide upward, so that the end of the sliding tube 303 slides upward along the inner wall of the inclined groove 305, and the two sealing boxes 304 are slid together, so as to effectively seal and protect the bottom of the storage box 4, so that the sample can be sealed immediately, reducing the contact time between the sample and the external environment, thereby reducing the risk of environmental contamination, and also ensuring the integrity of the sample in the swab 19 for subsequent testing;

[0040] During the sampling process, the sliding plate 301 drives the connecting plate 7 and the protrusion 8 to move downward synchronously through the first spring 6. The outer wall of the protrusion 8 corresponds to the inner wall of the slot 505. When the protrusion 8 moves down to a certain distance, the outer wall of the protrusion 8 will slide to the inner wall of the slot 505, thereby limiting the rotation of the fixed column 501 to prevent the swab 19 from shifting during the sampling process. Then, during the downward movement of the sliding plate 301, the first spring 6 will be compressed, and then the connecting plate 7 will drive the limiting rod 9 to stop moving. Then the sliding plate 301 will move along the outer wall of the limiting rod 9. When the sliding plate 301 is completely slid, the position of the second spring 10 will be higher than the upper surface of the sliding plate 301, and then the second spring 10 will be ejected by the elastic force of the abutment plate 11, so as to limit the limiting rod 9 and the sliding plate 301. After that, after the sampling is completed, the push plate 20 is released so that the sliding plate 301 is pulled by the tension of the first tension spring 13 to reset. When sliding, since the bottom of the second spring 10 is stuck on the surface of the sliding plate 301, the protrusion 8 is driven by the connecting plate 7 to disengage from the inner wall of the card slot 505, and then the rotation limit of the fixing column 501 is cancelled. During the process of the sealing box 304 being reset by the sliding plate 301, the sealing box 304 then drives the sliding rod 14 to move. During the movement of the sliding rod 14, the ratchet 504 is driven to rotate through the tooth groove 15, and then the ratchet 504 drives the fixed column 501 to rotate synchronously through the pawl 503. The bottom of the fixed column 501 is fixedly connected to the top of the storage box 4, and the bottom of the ratchet 504 is rotatably connected to the top of the storage box 4, so that the fixed column 501 drives the storage box 4 to rotate as a whole, so that the swab 19 corresponding to the abutment rod 306 no longer corresponds to it. The new swab 19 is rotated to a position corresponding to the bottom of the push rod 306, and the sliding plate 301 is reset at the same time. The sliding plate 301 drives the limiting rod 9 to slide into the inside of the slide tube 12 through the second spring 10. Then the inner wall of the slide tube 12 presses the top inclined surface of the second spring 10, and then the second spring 10 slides into the inside of the limiting rod 9. Then the connecting plate 7 is driven by the elastic force of the first spring 6 to drive the limiting rod 9 to slide downward to complete the reset. Since the storage box 4 rotates to make the new swab 19 correspond to the push rod 306, the next sampling work can be carried out directly.

[0041] After the sampling is completed, the sealing box 304 is reset by the sliding plate 301, and then the sealing box 304 drives the sliding rod 14 to move, so that the tooth groove 15 drives the ratchet 504 to rotate, and then the ratchet 504 will drive the storage box 4 to rotate as a whole through the fixed column 501, so that the new swab 19 rotates to the position corresponding to the bottom of the rod 306. Therefore, after the sampling is completed, the new swab 19 is automatically adjusted to the sampling position without manual intervention or waiting, and the next sampling is carried out directly, thereby improving the sampling efficiency and realizing the effect of continuous sampling without the need for a cleaning device.
