Description

TECHNICAL FIELD

[0001] The utility model relates to a sampling and preserving device, in particular to a cattle and sheep excrement rectal non - contact sampling device belongs to animal excrement sampling technical field. BACKGROUND

[0002] Cattle and sheep excrement sampling is an important means of livestock health monitoring, disease prevention and nutrition assessment. The traditional field cattle and sheep excrement sampling method usually directly uses a tool to scoop the sample and put it into a simple container for preservation. This method has many problems: first, the operator needs to contact the excrement sample closely, the sanitary condition is poor, and the operator is prone to discomfort and cross contamination; second, the sampling tool has a single function, and the sample is prone to spill during the transfer from the tool to the container, resulting in sampling failure and environmental pollution; in addition, some existing sampling devices have complex mechanical structures in order to achieve specific functions, which have the problems of inconvenient operation and low reliability in the field environment.

[0003] In the prior art, a full-automatic field excrement wrapping collector disclosed in publication No. CN218330653U includes a lower box body, a storage box, a baffle, a pressing plate, and a belt body structure driven by a storage belt wheel and a bag collecting wheel. By cooperating the pressing plate spring and the baffle spring, the excrement sample is automatically wrapped with the preservative film on the belt body and stored in the storage box, realizing rapid collection and avoiding direct contact. The device has a complex structure and relies on multiple springs and transmission components, and its action reliability and durability may be affected in the field harsh environment; and its sampling process still needs to move the sample from the collection site to the storage site, which has the risk of sample spilling or remaining inside the device, and cannot realize real sampling packaging. For example, a device for collecting and storing fresh excrement samples of wild animals disclosed in publication No. CN223188063U provides an integrated box body, which is internally provided with a storage chamber and a refrigeration chamber. The refrigeration chamber is internally provided with a refrigeration system and a temperature sensor, which maintains a low-temperature environment through a controller, and is equipped with collection tools such as disposable gloves, a collection spoon, a cryopreservation tube, and a sampling label device for recording sample information. However, the entire system of the device is relatively complex and relies on electronic devices such as refrigeration sheets and power supply systems, which has high manufacturing and maintenance costs and may not be portable and durable in a pure field livestock environment; secondly, the sampling method still needs the operator to use the collection spoon and other tools relatively close, which cannot completely realize zero contact during the sampling process, and the sanitary protection still has room for improvement.

[0032] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0033] Embodiment one

[0036] The storage box 1 is movably provided with a joystick assembly 3, which comprises a connecting outer tube 31 and a top rod 32 movably inserted in the connecting outer tube 31, and the connecting outer tube 31 is movably connected with the collection tank 21. When the collection assembly 2 is combined with the joystick assembly 3, the top rod 32 is coaxially connected with the push rod 25, so that the operator can indirectly drive the push rod 25 in the collection tank 21 by operating the top rod 32 on the joystick assembly 3 from a position away from the sample, thereby accurately controlling the opening and closing of the collection claw 4 and the sampling action, completely avoiding the direct contact of the operator's hands with the fecal sample, greatly improving the hygiene of sampling and the psychological comfort of the operator, and also suitable for sampling in difficult-to-reach positions.

[0037] Embodiment two

[0038] Based on the improvement of the first embodiment:

[0039] As shown in Figures 1 to 5 , the storage box 1 is provided with a heat preservation cavity 15, and the heat preservation cavity 15 is filled with a phase change material. The filled phase change material enables the entire storage box 1 to have an active temperature control capability. The phase change material can absorb or release a large amount of latent heat during the phase change such as melting or solidification, thereby being able to stably maintain the temperature in the box near the phase change point for a long time, for example, in a low temperature state, to provide a constant low temperature preservation environment for the collected cow and sheep fecal samples, greatly inhibiting the activity of microorganisms in the samples, effectively preventing the samples from deteriorating, and ensuring the accuracy of subsequent detection and analysis. It should be noted that the phase change material can be a heat-conducting phase change material disclosed in CN119930198A.

[0040] The upper end of the storage box 1 is connected with an upper cover 11, and the box body of the storage box 1 is also provided with a sample cavity 12 and an instrument cavity 14. The sample cavity 12 is annularly distributed with a plurality of sample cavities 12, and the instrument cavity 14 is located at the middle part of the storage box 1. The collection assembly 2 is arranged in the sample cavity 12, and the joystick assembly 3 is arranged in the instrument cavity 14. The storage box 1 is closed by the upper cover 11, which not only prevents external pollutants from entering the box, ensures the cleanliness of the collection assembly 2 during storage and transportation, but also better maintains the low temperature environment created by the heat preservation cavity 15, reduces the loss of cold quantity, and the annularly distributed sample cavities 12 can fully utilize the internal space of the storage box 1, accommodate the maximum number of collection tanks 21 in a limited volume, improve the sample carrying capacity of the equipment, meet the needs of multiple and multiple sample collection, and each collection assembly 2 is independently arranged in a sample cavity 12. This isolation method avoids the mutual collision and friction of multiple collection tanks 21 during transportation, prevents damage or cross contamination, ensures the independence of each sample, and makes the joystick assembly 3 very convenient to take and place in the centrally located instrument cavity 14.

[0041] Further, the inner wall of the sample cavity 12 is connected with an anti-skid strip 13, the bottom of the sample cavity 12 is provided with a fixed clamping groove 16, the bottom end of the collection tank 21 is movably connected with a bottom cover 22, the bottom surface of the bottom cover 22 is connected with a fixed block 27, and the fixed block 27 is clamped in the fixed clamping groove 16. It should be noted that the anti-skid strip 13 can be made of rubber, silicone or other high-friction coefficient materials to increase the static friction between the outer wall of the collection tank 21 and the inner wall of the sample cavity 12. When the collection tank 21 is inserted into the sample cavity 12, the anti-skid strip 13 will generate a tightening force on it, effectively preventing the collection tank 21 from shaking, rotating or falling off due to accidental collision in the cavity. When the clean collection tank 21 is taken out of the storage box 1, its bottom cover 22 is pre-covered, and the fixed block 27 is clamped in the fixed clamping groove 16. Since the fixed clamping groove 16 is fixed on the storage box 1, the circumferential rotation freedom of the bottom cover 22 is limited. At this time, the operator only needs to hold and rotate the tank body of the collection tank 21 to tighten the bottom cover 22 by using the rotating buckle structure between them, realizing the sealing before sampling. Conversely, when the collection tank 21 needs to be put back into the storage box 1 after sampling is completed, the fixed block 27 at the bottom of the bottom cover 22 is aligned and put into the fixed clamping groove 16, and the bottom cover 22 is also fixed. Then, reverse rotation of the tank body of the collection tank 21 can easily tighten and seal it with the bottom cover 22, and the operator does not need to touch the possibly contaminated bottom cover 22.

[0042] Further, the bottom end of the collection tank 21 is provided with a plurality of L-shaped clamping grooves 28, the edge of the bottom cover 22 is connected with a plurality of L-shaped clamping blocks 29, and the L-shaped clamping grooves 28 and the L-shaped clamping blocks 29 are correspondingly arranged. When the bottom cover 22 is closed, the operator only needs to align the L-shaped clamping blocks 29 on the bottom cover 22 with the vertical entrances of the L-shaped clamping grooves 28 at the bottom end of the collection tank 21, and then push axially to make the L-shaped clamping blocks 29 enter the vertical part of the L-shaped clamping grooves 28. When the L-shaped clamping blocks 29 reach the bottom, the collection tank 21 is slightly rotated to make the L-shaped clamping blocks 29 slide into the horizontal part of the L-shaped clamping grooves 28, thereby completing the locking and greatly improving the efficiency of field work.

[0043] As Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the top center of the collection tank 21 is connected with a guide pipe 23, a push rod 25 is movably inserted into the guide pipe 23, a pressure plate 210 is fixedly connected to the rod of the push rod 25 in the guide pipe 23, a reset spring 211 is movably sleeved on the rod of the push rod 25 in the guide pipe 23, and the reset spring 211 is below the pressure plate 210. The guide pipe 23 is connected at the top center of the collection tank 21 to provide accurate guidance and limiting for the push rod 25, to ensure that the push rod 25 can only move linearly in the vertical direction and cannot deviate, so that the pushing force transmitted by the push rod 32 is accurately and vertically transmitted downward, and finally converted into driving of the two collection claws 4 through the hinge seat 212, so that the two collection claws 4 can smoothly and synchronously perform the opening or closing action. When the operator presses the push rod 32 downward, the push rod 25 moves downward against the elastic force of the reset spring 211, thereby pushing the collection claws 4 to extend out of the collection tank 21 and open. When the sampling is completed, the operator releases the pressure on the push rod 32, at this time the elastic potential energy accumulated by the compressed reset spring 211 is released, and the reset spring 211 rebounds upward, pushes the pressure plate 210 and drives the push rod 25 to reset upward. The upward movement of the push rod 25 drives the two collection claws 4 to retract into the collection tank 21 and automatically close, thereby wrapping the collected sample. The operator does not need to perform an additional action of retracting the grab bucket, and only needs to release the hand to complete the sampling and closing. This not only improves the efficiency, but also ensures the consistency of each sampling action.

[0044] Further, the upper end of the guide pipe 23 is provided with external threads 24, the bottom end of the connecting pipe 31 is connected with a butt joint seat 35, the inner wall of the butt joint seat 35 is provided with internal threads 36, and the guide pipe 23 and the butt joint seat 35 are detachably connected through the thread engagement of the external threads 24 and the internal threads 36. It should be noted that the thread butt joint direction of the guide pipe 23 and the butt joint seat 35 is opposite to the screwing butt joint direction of the collection tank 21 and the bottom cover 22. Through the thread engagement of the external threads 24 and the internal threads 36, the guide pipe 23 and the butt joint seat 35 are detachably connected, which ensures the effective and lossless transmission of power from the operating rod assembly 3 to the collection assembly 2, avoids the connection from falling off or shaking under stress, and avoids cross contamination. After the sampling is completed, the operator needs to put the collection tank 21 back into the storage box 1 and rotate the collection tank 21 to tighten the bottom cover 22 which has been fixed through the fixed clamping groove 16. The action direction of rotating and tightening the collection tank 21 is consistent with the direction of loosening the connection between the operating rod assembly 3 and the collection tank 21, that is, in the process of rotating the collection tank 21 to tighten the bottom cover 22, the thread connection between the operating rod assembly 3 and the collection tank 21 becomes looser and looser, and finally separates. The operator does not need to additionally perform an action of rotating the operating rod assembly 3 in the opposite direction to detach, which ensures that the operator does not need to directly touch the collection tank 21 which has contacted the feces with his hand during the whole process, thereby preventing cross contamination.

[0045] Further, the top end of the push rod 25 is provided with a positioning groove 26, the bottom end of the top rod 32 is connected with a positioning block 37, and when the collection assembly 2 and the operating rod assembly 3 are in a combined state, the positioning block 37 is clamped in the positioning groove 26. It should be noted that the rod body of the top rod 32 is in a stepped shape, and the diameter of the lower part of the rod body of the top rod 32 inserted in the connecting outer tube 31 is greater than that of the upper part. By providing the positioning groove 26 at the top end of the push rod 25 and the positioning block 37 at the bottom end of the top rod 32, the circumferential positioning and axial guidance when the two are connected are realized, the relative rotation and deviation during power transmission are prevented, the pressing force of the top rod 32 can be accurately and completely applied to the push rod 25 along the center line, so that the collection claw 4 can be reliably driven to act, and the stepped rod body design of the top rod 32 can cooperate with the in-pipe component to play a mechanical limiting role, preventing the top rod from rebounding excessively.

[0046] Further, the upper end of the connecting outer tube 31 is fixedly connected with a limiting plate 33, and the top end of the top rod 32 is fixedly connected with a pressing cap 34. When the top rod 32 is pressed to the end of the stroke, the pressing cap 34 will contact the limiting plate 33, thereby preventing damage to the internal return spring 211, push rod 25 and grab linkage mechanism due to excessive pressing, greatly improving the durability and anti-misoperation ability of the device. At the same time, the limiting plate 33 also provides a stable support point for the palm of the operator, and the pressing cap 34 expands the force application area of the fingers, reducing hand fatigue during long-time operation.

[0047] As shown in Figure 3 , Figure 7 , Figure 9 and Figure 10 , the bottom end of the push rod 25 is fixedly connected with a hinged seat 212, the top ends of the two collection claws 4 are connected with hinged ears 41 arranged in a staggered manner, and the two hinged ears 41 are rotationally connected to the hinged seat 212. When the push rod 25 moves downward, it drives the hinged seat 212 to move downward, forcing the two grabbers to swing outward along the predetermined trajectory through the staggered connection of the hinged ears 41, thereby opening. When the push rod 25 rises under the action of the return spring, the hinged seat 212 rises with it, and through the linkage mechanism, the two grabbers are retracted and closed, tightly holding the sample, ensuring the synchronization and symmetry of the movement of the two grabbers, avoiding movement interference or jamming, and tightly closing to prevent sample leakage.

[0048] Further, the limiting sliding unit comprises a sliding rail 42 and a pulley 43, the sliding rail 42 is fixedly connected to the middle part of the outer side wall of the collecting claw 4 along the moving direction of the collecting claw 4, the pulley 43 is movably arranged in the sliding rail 42, the pulley 43 is rotatably connected with the inclined supporting rods 44 on both sides of the wheel body, the inclined supporting rods 44 are fixedly connected to the inner wall of the bottom end of the collecting tank 21 in a downward inclined manner, the sliding rail 42 defines the movement path of the grab bucket, the pulley 43 changes the sliding friction into rolling friction, greatly reduces the movement resistance, makes the operation easy and reduces the wear, and the inclined supporting rods 44 can provide a supporting base point and a guiding constraint for the movement of the grab bucket, accurately limit the grab bucket to move smoothly along the designed track, and effectively prevent the grab bucket from shaking, deviating or twisting.

[0049] Working principle: when operating, first open the upper cover 11 of the storage box 1, take out the operating rod assembly 3 from the instrument cavity 14, and take out a clean collecting assembly 2 from the annularly distributed sample cavity 12, connect the inner thread 36 of the butt joint seat 35 at the bottom end of the connecting outer tube 31 with the outer thread 24 of the guide pipe 23 at the top end of the collecting tank 21 by screwing, in this process, the alignment block 37 at the bottom end of the top rod 32 is inserted into the alignment groove 26 at the top end of the push top rod 25 to realize precise butt joint.

[0050] After the combination is completed, the hand-held operating rod assembly 3 aligns the collecting tank 21 with the fecal sample, presses down the pressing cap 34 at the top end of the top rod 32, the top rod 32 pushes the push top rod 25 to move downward against the resistance of the return spring 211, drives the two collecting claws 4 to move along the limiting sliding unit through the bottom hinge seat 212 and the misaligned hinge ears 41, guides the direction along the sliding rail 42, the pulley 43 rolls in the sliding groove of the sliding rail 42, makes the grab bucket extend out of the tank and open to grab the sample, after the pressing cap 34 is loosened, the return spring 211 pushes the pressure plate 210 to reset the push top rod 25, the grab bucket is retracted into the tank and closes to wrap the sample;

[0051] After sampling, the collecting tank 21 is placed back into the storage box 1, the fixing block 27 at the bottom of the bottom cover 22 is clamped into the fixed clamping groove 16 at the bottom of the sample cavity 12 to fix the bottom cover 22, at this time, the tank body of the collecting tank 21 is rotated, the bottom end L-shaped clamping groove 28 is matched with the L-shaped clamping block 29 on the bottom cover 22 to be tightly sealed, since the tightening direction is consistent with the loosening direction of the thread circle at the connecting part, the rotating action automatically separates the operating rod assembly 3 from the collecting tank 21 while sealing the collecting tank 21, realizes non-contact operation, finally, multiple sealed samples are stored in the storage box 1 and are kept in a low-temperature environment by the phase change material in the heat preservation cavity 15, which guarantees the sample quality.
