Description
Technical Field
[0001] The invention relates to the technical field of sampling and detection, and more specifically to a sampling and detection device used in animal husbandry and veterinary medicine. Background Art
[0002] Livestock feces may contain various microorganisms, including bacteria, viruses, parasites and their eggs, etc. The presence of these microorganisms is closely related to the health of the animals. Veterinarians assess the health of livestock by culturing fecal bacteria and testing for parasitic diseases, so it is necessary to obtain a sufficient amount of fecal samples.
[0003] The common method of sampling and testing livestock feces is to use a swab. Due to the influence of the volume of the swab and the viscosity of the feces, when the swab rises after sampling, the feces sample that sticks to it has no lifting force and is easy to fall off, resulting in a small single sampling volume. When there are many test items or the amount of livestock feces is large, in order to improve the accuracy of the test results, a sufficient amount of samples must be obtained, and then the test personnel need to repeatedly sample multiple times, resulting in low sampling efficiency and increased difficulty in sampling operations. In view of this, we propose a sampling and testing device for animal husbandry and veterinary medicine. Summary of the invention
[0004] The purpose of the present invention is to provide a sampling and detection device for animal husbandry and veterinary medicine, which solves the technical problems in the prior art of low efficiency of animal feces sampling by swab, small single sampling volume, and the need for repeated sampling.
[0005] The embodiment of the present invention provides a sampling and detection device for animal husbandry and veterinary medicine, comprising a fixed tube, a storage component and a sampling component; The storage assembly comprises a storage box, a sampling slot is provided on the storage box, and the storage box is slidably connected to the fixed pipe; The sampling assembly includes a driving rod, the bottom of which is inserted into the storage box and fixedly connected to a rotating block, the rotating block is rotatably connected to the storage box, a storage area is formed between the rotating block and the storage box, and a plurality of sampling plates are installed on the rotating block; The rotating block drives the sampling plate to move downward and rotate relative to the fixed tube, so that the positions of the sampling plates are switched between the storage area and the sampling slot area, and the samples to be sampled between the sampling plates are continuously sent into the storage area.
[0006] By adopting the above technical solution, a sampling slot is opened on one side of the storage box and a rotatable sampling plate is arranged in the storage box. When sampling, the sampling plate in the sampling slot area is inserted into the feces to be sampled and rotated, so that the feces is sent into the storage area. By alternately switching the positions of a plurality of sampling plates at the sampling slot, the feces are continuously sampled, and the sampling efficiency and sampling amount are effectively improved; at the same time, when the sampling plate is transferred into the storage area, a relative storage space can be formed between the rotating block and the storage box, and the sampling plate effectively separates the two open ends of the storage area. After the sampling is completed, when the storage box and the sampling plate are pulled away from the feces, the problem of the collected feces falling out of the storage box can be avoided, and the stability of the sampling amount can be effectively guaranteed.
[0007] As an optional solution of the technical solution of the present application document, two sets of adjustment blocks are fixedly installed on the storage box; The sampling assembly also includes a plurality of elastic members, a plurality of guide grooves are provided on the rotating block, a plurality of sampling plates slide in the corresponding guide grooves, a plurality of elastic members are in the corresponding guide grooves, one end of the elastic member is fixedly connected to the corresponding sampling plate, and the other end of the elastic member is fixedly connected to the rotating block.
[0008] By adopting the above technical solution, when the sampling plate rotates from the storage area to the sampling slot area, the limitation of the sampling plate by the inner wall of the storage box disappears, and under the action of the elastic member, the sampling plate extends radially outward along the rotating block, thereby increasing the area of feces that can be scraped when the sampling plate rotates.
[0009] As an optional solution to the technical solution of the present application document, the storage box is cylindrical and hollow inside, the outer diameter of the storage box is smaller than the inner diameter of the fixed tube, the arc length of the sampling groove is not greater than one quarter of the total arc length of the storage box, the adjustment block is installed in the sampling groove and distributed on both sides of the sampling groove, and the adjustment block is provided with a first inclined surface and a second inclined surface.
[0010] As an optional solution of the technical solution of the present application document, a third inclined surface is provided at the bottom of the storage box, and the vertical distance between the third inclined surface and the bottom surface of the sampling plate gradually increases from the vertical center line of the sampling slot and along the radial direction of the storage box.
[0011] As an optional solution of the technical solution of the present application document, the rotating block is cylindrical, the rotating block is colinear with the axis of the storage box, and a fourth inclined surface is provided on the sampling plate.
[0012] As an optional solution of the technical solution of the present application document, a plurality of inclined plates are fixedly installed on both sides of the sampling plate, a limit plate is fixedly installed on the driving rod, and the top of the storage box is located between the limit plate and the rotating block.
[0013] By adopting the above technical solution, an inclined plate is provided on the sampling plate, which reduces the risk of feces detaching from the sampling plate due to feces adhesion during the rotation process, and further improves the stability of sampling.
[0014] As an optional solution to the technical solution of the present application document, the fixed tube includes a tube body with open ends, a fixing frame fixedly installed on the top of the tube body, the storage box is slidably connected to the fixing frame through a plurality of telescopic rods, a guide hole is opened on the fixing frame, and the driving rod is movably inserted in the guide hole and passes through the guide hole.
[0015] As an optional solution of the technical solution of the present application document, a threaded pipe is fixedly installed below the fixing frame, and the axis of the threaded pipe is colinear with the axis of the guide hole; A thread block is fixedly mounted on the driving rod, and the thread block is used for locking with the thread of the threaded pipe.
[0016] By adopting the above technical solution, the threaded block is used to lock the thread of the threaded pipe. When not in use, the handle is pulled to move upward relative to the tube body, driving the driving rod, the rotating block, a plurality of sampling plates and the storage assembly to move upward, and the fourth inclined surface of the sampling plate in the sampling groove contacts the bottom of the tube body, so that the sampling plate compresses the corresponding elastic member and moves into the rotating block. When the threaded block abuts against the threaded tube, the storage assembly is completely received in the tube body, and the handle is rotated to drive the driving rod and the threaded block to rotate, thereby locking the threaded block in the threaded tube, completing the storage and fixation of the storage assembly and the sampling plate.
[0017] As an optional solution of the technical solution of the present application document, a plurality of through holes are opened on the top of the storage box.
[0018] By adopting the above technical solution, the sampling personnel holds the tube body with one hand and presses the handle downward with the other hand to drive the driving rod, the rotating block and the storage assembly to move downward. After the sampling plate corresponding to the sampling slot area extends out of the tube body, under the action of the corresponding elastic member, the corresponding sampling plate in the sampling slot area slides outward along the radial direction of the rotating block to increase the radial sampling range. The sampling personnel keeps the tube body still, rotates and presses down the handle to insert the bottom of the storage box into the feces, and the sampling plate corresponding to the sampling slot is inserted into the feces. When the handle is rotated, the driving rod, the rotating block and a plurality of sampling plates are driven to rotate; As the handle rotates and descends, the sampling plate follows the descending and rotation, thereby driving the feces accumulated between the two sampling plates to rotate. When the fourth inclined surface of the sampling plate rotates to contact the bottom of the first inclined surface, the sampling plate compresses the corresponding elastic member to slide into the guide groove until the maximum outer diameter of the sampling plate relative to the axis of the rotating block is smaller than the inner diameter of the storage box. After the sampling plate passes through the second inclined surface and the corresponding elastic member and is adjusted again, the sampling plate is fixed on the inner wall of the storage box, and the feces are pushed into the storage area; When one sampling plate rotates from the sampling slot area to the storage area, the other sampling plate rotates from the storage area to the sampling slot area. After the sampling plate moves to the sampling slot area, it loses the limit of the storage box. The corresponding elastic member drives the sampling plate in the sampling slot area to slide out along the radial direction of the rotating block. By continuously rotating and pressing down the handle, the feces is continuously rotated and brought into the storage area, effectively improving the storage capacity and storage stability of feces.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present invention provides a sampling slot on one side of a storage box and sets a rotatable sampling plate in the storage box. When sampling, the sampling plate in the sampling slot area is inserted into the feces to be sampled and rotated, so that the feces are sent into the storage area. By alternately switching the positions of a plurality of sampling plates at the sampling slot, the feces are continuously sampled, and the sampling efficiency and sampling amount are effectively improved. At the same time, when the sampling plate is transferred into the storage area, a relative storage space can be formed between the rotating block and the storage box. The sampling plate effectively separates the two open ends of the storage area. After the sampling is completed, when the storage box and the sampling plate are pulled away from the feces, the problem of the collected feces falling out of the storage box can be avoided, and the stability of the sampling amount can be effectively guaranteed.
[0020] 2. The sampling plate of the present invention also has the function of increasing the sampling range. When the sampling plate rotates from the storage area to the sampling slot area, the limit of the sampling plate by the inner wall of the storage box disappears. Under the action of the elastic member, the sampling plate extends radially outward along the rotating block, thereby increasing the area of feces that can be scraped when the sampling plate rotates. At the same time, an inclined plate is provided on the sampling plate. During the rotation process, the risk of feces detaching from the sampling plate due to feces adhesion is reduced, thereby further improving the stability of sampling.
[0021] 3. The sampling plate of the present invention can be sampled in both clockwise and counterclockwise directions, which effectively reduces the difficulty of sampling operation and improves the fault tolerance of operation. The rotation of the sampling plate from the storage area to the sampling slot area or from the sampling slot area to the storage area is controlled by the inclined surface on the adjustment block, thereby achieving a smooth transition of the extension or return of the sampling plate, effectively avoiding the problem of vibration caused by excessive extension and contraction of the sampling plate.
[0022] 4. The arc length of the sampling slot of the present invention is no greater than one quarter of the total arc length of the storage box. When the sampling plate is rotated for storage, it has a larger sample storage range, further increasing the amount of samples that can be stored.
[0023] 5. The present invention immerses or semi-immerses the storage box and the rotating block in a container filled with a protective liquid. The rotating handle drives the sampling plate to rotate. The protective liquid is brought into the storage area from the through hole or by the rotation of the sampling plate to mix with feces. As the sampling plate continues to rotate, the mixed feces flows out from the other end of the storage area and enters the container, effectively reducing the difficulty of the sample removal operation.

[0026] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] Reference Figure 1 The present embodiment discloses a sampling and detection device for animal husbandry and veterinary medicine, including a fixed tube 1 and a storage assembly 2. The fixed tube 1 includes a tube body 11, and both ends of the tube body 11 are open. A fixing frame 12 is fixedly installed on the top of the tube body 11, and a guide hole 13 is opened on the fixing frame 12. A threaded tube 14 is fixedly installed below the fixing frame 12, and the axis of the threaded tube 14 is colinear with the axis of the guide hole 13.
[0028] Reference Figures 1 to 5 The storage assembly 2 includes a storage box 21, which is cylindrical. The outer diameter of the storage box 21 is smaller than the inner diameter of the tube body 11. The storage box 21 is hollow inside. A sampling slot 22 is provided on the storage box 21. The arc length of the sampling slot 22 is not greater than one-fourth of the total arc length of the storage box 21. Two groups of adjustment blocks 23 are fixedly installed on the storage box 21. The adjustment blocks 23 are installed in the sampling slot 22 and are distributed on both sides of the sampling slot 22. A first inclined surface 24 and a second inclined surface 25 are provided on the adjustment blocks 23. A plurality of through holes 26 are provided on the top of the storage box 21. A third inclined surface 27 is provided on the bottom of the storage box 21. The storage box 21 is slidably connected to the fixed frame 12 through a plurality of telescopic rods 3. The telescopic rod 3 includes a sleeve and an extension rod. The extension rod slides in the sleeve. One end of the sleeve is fixed on the fixed frame 12, and one end of the extension rod is fixed on the storage box 21.
[0029] Reference Figures 1 to 8 A sampling assembly 4 is installed on the storage box 21. The sampling assembly 4 includes a driving rod 41, which is movably inserted in the guide hole 13. The driving rod 41 passes through the guide hole 13 and is inserted into the storage box 21. A rotating block 42 is fixedly installed at the bottom of the driving rod 41. The rotating block 42 is cylindrical. The rotating block 42 is rotatably connected to the storage box 21. The rotating block 42 is colinear with the axis of the storage box 21. A storage area 43 is formed between the rotating block 42 and the storage box 21. A plurality of guide grooves 44 distributed in a circular array are opened on the rotating block 42. A sampling plate 45 is slidably connected in the guide groove 44. Starting from the vertical center line of the sampling groove 22 and along the radial direction of the storage box 21, the vertical spacing between the third inclined surface 27 and the bottom surface of the sampling plate 45 gradually increases.
[0030] The sampling plate 45 is provided with a fourth inclined surface 46. When the sampling assembly 4 is upwardly received into the tube body 11, the bottom of the tube body 11 abuts against the fourth inclined surface 46, thereby assisting the sampling plate 45 to slide into the guide groove 44. The sampling assembly 4 also includes a plurality of elastic members 47. The elastic members 47 are located in the corresponding guide grooves 44. One end of the elastic member 47 is fixedly connected to the corresponding sampling plate 45, and the other end is fixedly connected to the rotating block 42, and is used to push the sampling plate 45 toward the outside of the rotating block 42. A plurality of inclined plates 48 are fixedly installed on both sides of the sampling plate 45. The inclined plates 48 are inclined toward one side of the rotating block 42, thereby increasing the The sampling amount during feces sampling is determined by a limit plate 49 fixedly mounted on the driving rod 41, and the top of the storage box 21 is located between the limit plate 49 and the rotating block 42, thereby ensuring that when the driving rod 41 descends, the storage box 21 follows and descends synchronously, and when the driving rod 41 rotates, the storage box 21 does not rotate, and a handle 410 is fixedly mounted on one end of the driving rod 41 away from the rotating block 42, and a threaded block 5 is fixedly mounted on the driving rod 41, and the threaded block 5 can be threadedly locked with the threaded tube 14, so that the storage component 2 and the sampling component 4 are received and fixed in the tube body 11, and the storage component 2 and the sampling component 4 are effectively protected.
[0031] Working principle: the sampling personnel holds the tube body 11 with one hand and presses the handle 410 downward with the other hand, driving the driving rod 41, the rotating block 42 and the storage assembly 2 to move downward. After the sampling plate 45 corresponding to the sampling slot 22 area extends out of the tube body 11, under the action of the corresponding elastic member 47, the corresponding sampling plate 45 in the sampling slot 22 area slides outward along the radial direction of the rotating block 42, thereby increasing the radial sampling range. The sampling personnel keeps the tube body 11 stationary, rotates and presses down the handle 410 to insert the bottom of the storage box 21 into the feces, and the sampling plate 45 corresponding to the sampling slot 22 is inserted into the feces. When the handle 410 rotates, it drives the driving rod 41, the rotating block 42 and several sampling plates 45 to rotate.
[0032] As the handle 410 rotates and descends, the sampling plate 45 follows the descending and rotation, thereby driving the feces accumulated between the two sampling plates 45 to rotate. When the fourth inclined surface 46 of the sampling plate 45 rotates to contact the bottom of the first inclined surface 24, the sampling plate 45 compresses the corresponding elastic member 47 to slide into the guide groove 44 until the maximum outer diameter of the sampling plate 45 relative to the axis of the rotating block 42 is smaller than the inner diameter of the storage box 21. After the sampling plate 45 is adjusted again after passing through the second inclined surface 25 and the corresponding elastic member 47, the sampling plate 45 is fixed on the inner wall of the storage box 21, and the feces is pushed into the storage area 43.
[0033] When one sampling plate 45 rotates from the sampling slot 22 area to the storage area 43, the other sampling plate 45 rotates from the storage area 43 to the sampling slot 22 area. After the sampling plate 45 moves to the sampling slot 22 area, it loses the limit of the storage box 21. The corresponding elastic member 47 drives the sampling plate 45 in the sampling slot 22 area to slide out along the radial direction of the rotating block 42. By continuously rotating and pressing down the handle 410, the feces is continuously rotated and brought into the storage area 43, effectively improving the storage capacity and storage stability of the feces.
[0034] When mixing the sampled feces into the protective liquid, the storage box 21 and the rotating block 42 are immersed or semi-immersed in a container filled with the protective liquid, and the handle 410 is rotated to drive the sampling plate 45 to rotate. The protective liquid is brought into the storage area 43 from the through hole 26 or by the rotation of the sampling plate 45 to mix with the feces. As the sampling plate 45 continues to rotate, the mixed feces flows out from the other end of the storage area 43 and enters the container.
[0035] When the sampling detection device is cleaned, the cleaning liquid is continuously introduced into the top of the tube body 11 and the handle 410 is continuously rotated, so that the sampling plate 45 is driven to rotate in the storage area 43. The cleaning liquid enters the storage area 43 from the tube body 11 through the through hole 26, thereby cleaning the storage box 21 and the sampling plate 45.
[0036] When the sampling detection device is not in use, the handle 410 is pulled to move upward relative to the tube body 11, driving the driving rod 41, the rotating block 42, a plurality of sampling plates 45 and the storage assembly 2 to move upward, and the fourth inclined surface 46 of the sampling plate 45 in the sampling slot 22 contacts the bottom of the tube body 11, so that the sampling plate 45 compresses the corresponding elastic member 47 and moves into the rotating block 42. When the threaded block 5 abuts against the threaded tube 14, the storage assembly 2 is completely received in the tube body 11, and the handle 410 is rotated to drive the driving rod 41 and the threaded block 5 to rotate, thereby locking the threaded block 5 in the threaded tube 14, and completing the fixation of the storage assembly 2 and the sampling plate 45.
[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
