Description

Technical Field

[0001] The invention relates to the technical field of sampling and quarantine, in particular to a sampling method for veterinary quarantine. Background Art

[0002] Feces can directly reflect the health status of livestock. Through the collection and quarantine of livestock feces, timely detection and human intervention, the spread of viruses between livestock can be reduced, which is conducive to reducing the mortality rate of livestock.

[0003] There are two main methods of feces collection commonly used by veterinarians in the prior art. A sampling cotton swab is used to take feces in the middle of the feces pile and put it in a sampling bottle for dilution and preservation; or a tool is used to insert it into the feces pile, and the feces on the surface of the feces pile is pushed away with the collection tool, and then the feces in the middle is clamped or sucked. After sampling, the feces sample is transferred to a sampling bottle for storage and inspection. The instrument sampling in the prior art still requires manual pre-pushing of feces.

[0004] In order to avoid the above problems, in view of this: Chinese patent CN117740430A discloses a sampling device for veterinary quarantine and a sampling method thereof, comprising a disposable sampling tube and a collection handle fixedly arranged on the disposable sampling tube, a sampling inner tube fixedly arranged inside the disposable sampling tube, a spiral crushing component rotatably arranged inside the sampling inner tube for preventing feces from clogging, a sampling device for veterinary quarantine and a sampling method thereof of the present invention, a disposable sampling tube design is adopted in the veterinary quarantine sampling device, and a two-link pushing component is built in, which can be directly inserted into the dung pile of the livestock to be sampled, and the surface feces are automatically pushed away, and the feces in the middle of the dung pile are sampled, the sampling operation is simple, and the veterinarian does not need to manually push the feces for sampling, which is more hygienic and more efficient; a spiral crushing component is added in the disposable sampling tube, and the feces can be pushed and the crude fiber in the feces can be cut by the spiral pushing method, which is convenient for sampling, not prone to clogging, and the sampling is smoother.

[0005] Although the above solves the inconvenience of manually pushing away feces and improves the effect of spiral sampling, it is inevitable that there are still some shortcomings in the actual use process. For example, the various preparations of the device lack necessary connection, resulting in the overall sampling process being relatively scattered, resulting in the device being not convenient and smooth to use, and the device lacks an odor evacuation mechanism, so that there will be a pungent smell during sampling, which affects the comfort of using the device. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a sampling method for veterinary quarantine, which solves the problems that the overall sampling process of the device is relatively scattered, resulting in loose connection of the sampling process and inconvenient use, and lacks an odor evacuation mechanism, resulting in the problem that the odor affects the user's senses during the use of the device.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-11 The present invention provides a technical solution: a sampling method for veterinary quarantine, which specifically comprises the following steps: Step 1: Collect feces. Hold the handle 610 to insert the inlet end of the sampling tube 1 into the inner layer of the feces pile, then hold the handle ring 605 tightly. The right side of the handle ring 605 is forced to move, and the first tooth plate 606, the second tooth plate 607 and the gear 608 are synchronously engaged, which causes the transfer tube 2 to extend out of the sampling tube 1 and expand the baffle 609, and then contact with feces. The handle ring 605 moves closer to the handle 610, synchronously driving the first tooth plate 606 to move, and the first The tooth plate 606 moves to mesh with the gear 608 and the second tooth plate 607, causing the second tooth plate 607 to drive the transfer cylinder 2 and the screw conveying shaft 3 to move to the left. The transfer cylinder 2 moves to expand the elastically compressed baffle 609 outward. The expansion of the baffle 609 will push away the outer feces, causing the transfer cylinder 2 and the screw conveying shaft 3 to contact the inner layer of feces. The screw conveying shaft 3 moves with the transfer cylinder 2, and synchronously drives the polygonal slide bar 604 to slide inside the inner polygonal rotating sleeve 602. Step 2, sample extraction, by tightly holding the ring sleeve 605 with the handle 610, the servo motor 601 is automatically started, and the inner polygonal rotating sleeve 602, the fan blade 603 and the spiral conveying shaft 3 are driven to rotate synchronously, and the sample extraction is completed while the odor is dissipated. During the process of the ring sleeve 605 with the handle tightly holding the handle 610, the ring sleeve 605 with the handle will press the control button 611 set on the side of the handle 610, and the control button 611 is stressed, and the servo motor 601 is started, and the servo motor 601 synchronously drives the inner polygonal rotating sleeve 602 and the fan blade 603 to rotate. The rotation of the fan blade 603 will evacuate the odor in the sampling range and accelerate the air circulation; The rotation of the inner polygonal rotating sleeve 602 synchronously drives the polygonal sliding rod 604 to rotate, and the rotation of the polygonal sliding rod 604 drives the spiral conveying shaft 3 to rotate inside the transfer cylinder 2. Since the spiral conveying shaft 3 is in contact with the feces, the spiral conveying shaft 3 continuously conveys the feces spirally to the inside of the transfer cylinder 2 in sequence, and then transfers it to the inside of the sampling long cylinder 5 through the transfer cylinder 2 and the regulating cylinder 4. After the sampling long cylinder 5 is fed, the material receiving pipe 805 correspondingly discharges and extracts the sample; Step 3: Holding and positioning. During the process of the handle ring sleeve 605 and the grip 610 being tightly fitted together, the handle ring sleeve 605 limits the holding distance between the handle ring sleeve 605 and the grip 610 through the positioning mechanism 7. During the movement of the handle ring sleeve 605 toward the grip 610, the handle ring sleeve 605 simultaneously drives the vertical plug ring 702 to move. When the vertical plug ring 702 moves, it moves along the wide surface of the step plate 804. When the handle ring sleeve 605 carries the vertical plug ring 702 to the bottom of the limiting slot 704, the vertical plug ring 702 rises due to the elastic tension of the second return spring 703, prompting the vertical plug ring 702 to fit and limit the limiting slot 704. Then, the grip of the handle ring sleeve 605 can be relaxed. When the vertical plug ring 702 rises, the corresponding inner wall of the vertical plug ring 702 will contact the narrow surface of the step plate 804. Step 4, original reset, during the sampling process of the sampling cylinder 5 through the sampling mechanism 6, the automatic reset mechanism 8 drives the positioning mechanism 7 to release the limit after the sample extraction is completed, so that the transfer cylinder 2 is automatically retracted into the sampling cylinder 1 and the sampling is stopped automatically. Along with the internal feeding of the sampling cylinder 5, the rubber piston 801 inside the sampling cylinder 5 will contact the feed delivered to the inside of the sampling cylinder 5, and through the continuous squeezing of the feed, the rubber piston 801 will gradually compress and move to the right. The movement of the rubber piston 801 to the right will gradually expose several material receiving pipe openings 805 discharge ports in sequence. After the material receiving pipe openings 805 discharge ports are exposed, the feed will flow into the interior of the sampling tube 807 through the material receiving pipe opening 805. Correspondingly, after the rightmost sampling tube 807 accepts the sampling, the rubber piston 801 will move The rod 803 carries the step plate 804 to move to the right. The movement of the step plate 804 will gradually separate the narrow side from the vertical plug ring 702 and bring the wide side into contact with the vertical plug ring 702. Since the vertical plug ring 702 rises, its inner wall is higher than the wide side of the vertical plug ring 702. Therefore, when the wide side is in contact with it at an angle, the vertical plug ring 702 will be pressed down, causing the vertical plug ring 702 to disengage from the limiting slot 704. After the vertical plug ring 702 is disengaged from the limiting slot 704, the transfer cylinder 2 is reset by the tension of the first reset spring 11, driving the second tooth plate 607 to retract into the sampling cylinder 1. The corresponding second tooth plate 607 retracts, and the first tooth plate 606 also engages and resets and drives the handle ring sleeve 605 to move to its original position. The handle ring sleeve 605 is reset, the control button 611 loses force, and the servo motor 601 stops automatically.
