DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The livestock breeding poultry quarantine sampling device disclosed in the embodiments mainly solves the problem that the existing quarantine sampling device is difficult to classify and sample poultry blood and feces, and cannot accurately determine whether the poultry population is infected with pathogens or immune qualified through multiple types of samples.

[0027] Positioning disc 1: as the basic bearing component of the device, used for mounting rotating ring 2, temporary storage cylinder 10, first motor 16 and mounting plate 19, and frame opening 9 is provided to realize the falling channel of the fecal sample.

[0028] Rotating ring 2: arranged on the upper edge of positioning disc 1, the inner side is provided with a sliding groove matched with lead screw 3. Lead screw 3 provides upward and downward sliding guide support to ensure that lead screw 3 keeps vertical stability when driving top disc 4 to displace.​​

[0029] Lead screw 3 and top disc 4: a vertical hole 8 is provided in the middle of the lead screw 3 for the sampling needle to pass through; the bottom end is threadedly connected with the screen plate 18, and the self-up and down displacement can be realized by rotating.

[0030] Top disc 4: made of ABS engineering plastic, the top edge is uniformly distributed with a plurality of hinged seats for connecting and restraining the leaf 5; and the top end is movably connected with the lead screw 3 through a deep groove ball bearing, which can move up and down with the lead screw 3 but does not rotate with the lead screw 3.

[0031] Restraint leaf 5: made of elastic PP plastic, a plurality of sampling ports are provided on the surface, and the edge is polished into a circular arc shape to avoid damaging the poultry skin. One end of each restraint leaf 5 is hinged with the top disc 4 through a hinge, and the other end is connected with the rotating ring 15 through a hinged rod 7; when the rotating ring 15 rotates, it drives the restraint leaf 5 to open and close through the hinged rod 7, realizing the wrapping and restraint of the poultry body.

[0032] Hinged rod 7: both ends are hinged with the restraint leaf 5 and the rotating ring 15 through fish eye bearings, which have a certain bending resistance.

[0033] Rotating ring 15: made of aluminum alloy, the outer side is sleeved with a gear ring 24, located between the rotating ring 2 and the positioning disc 1, and movably connected with the positioning disc 1 through a thrust ball bearing, which can rotate around the center axis of the positioning disc 1.

[0034] Temporary storage cylinder 10: made of transparent PC material, the top is sealingly communicated with the frame opening 9 of the positioning disc 1; one side is embedded with an electric push rod 11, and the end close to the positioning disc 1 is provided with a slot for inserting the baffle 14. As a storage and driving carrier of the sampling needle, it also receives the fecal samples falling from the frame opening 9, realizing the temporary storage of the samples.

[0035] Electric push rod 11: model XTL100, fixed in the embedded slot of the temporary storage cylinder 10 through bolts, and rigidly connected with the top rod 12. After receiving the control signal, it drives the top rod 12 to move along the axial direction, pushes the sampling needle to pass through the vertical hole 8 to complete the blood sampling, or drives the sampling needle to reset in the temporary storage cylinder 10. The top rod 12 is made of stainless steel, and the suction cup 13 is made of medical silicone, and the suction end is provided with a groove matched with the sampling needle for fixing the sampling needle such as disposable blood sampling needle. The top rod 12, the suction cup 13 and the vertical hole 8 are coaxially arranged to ensure that the sampling needle accurately passes through the vertical hole 8.

[0036] The baffle 14 is made of acrylic plate, one end extends outside the temporary storage cylinder 10 for easy manual insertion and removal. Before sampling, it is inserted into the temporary storage cylinder 10 to block the passage below the frame opening 9 to prevent impurities from falling in during non-sampling period; when sampling feces, it is pulled out to make the fecal sample fall into the temporary storage cylinder 10 through the frame opening 9.

[0037] The first motor 16 is a stepping motor fixed on the outside of the positioning disc 1 through an angle iron support and a bolt, and the output end is connected with the gear 17 through a shaft coupling. The gear 17 is engaged with the gear ring 24 on the outside of the rotating ring 15. After receiving a pulse signal, the motor drives the gear 17 to rotate, drives the rotating ring 15 to rotate through the gear ring 24, and then controls the opening and closing angle of the constraint leaf 5.

[0038] The screen plate 18 has two layers, and the edges are fixed in the middle of the rotating ring 15 through bolts. The upper layer has a screen aperture of 5 mm for filtering feathers and impurities in the feces, and the lower layer has a screen aperture of 2 mm for further screening small fecal particles. Both layers of the screen are inclined downward towards the frame opening 9, facilitating the sample to slide into the temporary storage cylinder 10. The fecal sample falling from the frame opening 9 is screened in two stages to remove impurities and ensure the purity of the subsequent detection sample.

[0039] The mounting plate 19 is vertically fixed on one side of the positioning disc 1 through a bolt, and a bearing hole is formed on the surface for installing the rotating shaft of the sector tooth 20. The sector tooth 20 is fixed and welded with a limiting rib 21 on one side. The sector tooth 20 is rotatably connected with the mounting plate 19 through the rotating shaft.

[0040] The limiting rib 21 is arc-shaped, with an arc that matches the outer wall of the temporary storage cylinder 10. One end is welded on the sector tooth 20, and the other end is fixed on the positioning disc 1 through a bolt. It is wrapped around the outside of the temporary storage cylinder 10 to limit the radial position of the temporary storage cylinder 10, preventing it from shaking or moving during sampling.

[0041] The second motor 22 is a stepping motor fixed on one side of the mounting plate 19 through a support, and the output end is rigidly connected with the worm 23.

[0042] The worm 23 is engaged with the sector tooth 20. After receiving a control signal, the motor drives the worm 23 to rotate, drives the sector tooth 20 to fine-tune the angle, and then adjusts the clamping force of the temporary storage cylinder 10 through the limiting rib 21, adapting to temporary storage cylinders 10 of different diameters or compensating for wear clearance.

[0043] The specific working principle is as follows: first, place the birds to be quarantined, such as adult chickens, above the top disc 4, ensuring that the center of the bird's body is aligned with the center of the top disc 4, avoiding positional deviation during subsequent sampling; at the same time, check the status of the temporary storage cylinder 10: insert the baffle 14 into the slot of the temporary storage cylinder 10 to block the passage below the frame opening 9, preventing impurities such as dust and feather debris from falling into the temporary storage cylinder 10 during non-sampling periods, affecting the purity of the sample; and fix the disposable blood sampling needle on the top rod 12 through the suction cup 13, ensuring that the blood sampling needle, the top rod 12, the suction cup 13, and the vertical hole 8 are on the same axis, preparing for subsequent precise blood sampling.

[0044] The PLC controller sends a pulse signal to the first motor 16 to start the first motor 16: the output end of the first motor 16 drives the gear 17 to rotate through the shaft coupling, since the gear 17 is engaged with the gear ring 24 on the outside of the rotating ring 15, the gear 17 will drive the rotating ring 15 to rotate clockwise around the center axis of the positioning disc 1 during rotation; during the rotation of the rotating ring 15, the hinge rod 7 hinged on the outside thereof will synchronously pull the constraint leaves 5 to fold towards the center, the hinge rod 7 is connected with the constraint leaves 5 and the rotating ring 15 through the fish eye bearing at both ends respectively, which can adapt to multi-angle transmission, until all the constraint leaves 5 are closely attached to the outside of the poultry body, realizing stable constraint of the poultry and avoiding operation failure caused by poultry struggling during sampling;

[0045] If it is necessary to adjust the height of the poultry blood sampling site, the PLC controller can be used to control the first motor 16 to finely adjust the rotating speed of the rotating ring 15, and the rotating ring 15 drives the screen plate 18 in the middle to rotate synchronously, since the screen plate 18 is threadedly connected with the bottom end of the lead screw 3, the screen plate 18 will drive the lead screw 3 to displace up and down along the sliding groove in the middle of the rotating ring 2 during rotation, and the top disc 4 is movably connected with the top end of the lead screw 3 through the deep groove ball bearing, so that the lead screw 3 will drive the top disc 4 to move up and down synchronously with the poultry during displacement, until the sampling port 6 on the constraint leaf 5 accurately aligns with the blood sampling site of the poultry body, further, during the process of constraining the poultry, constraint leaves 5 of different sizes and lead screws 3 of different lengths can be designed to adapt to different displacement strokes of the constraint leaves 5 and the top disc 4, and then different sizes of poultry can be adapted, and the displacement stroke of the blood sampling needle can also be adjusted by the electric push rod 11 to adapt the blood sampling stroke.

[0046] When the sampling port 6 aligns with the blood sampling site, the PLC controller sends a start signal to the electric push rod 11: the output end of the electric push rod 11 pushes the top rod 12 to move forward along the axial direction, the top rod 12 drives the suction cup 13 and the fixed blood sampling needle to move synchronously, the blood sampling needle passes through the vertical hole 8 in the middle of the lead screw 3, and finally penetrates into the poultry body to complete blood collection; after blood collection, the PLC controller sends a reverse signal to the electric push rod 11, the electric push rod 11 drives the top rod 12, the suction cup 13 and the blood sampling needle to move reversely, so that the blood sampling needle is reset to the temporary storage cylinder 10, then the operator removes the blood sampling needle to package and label the blood sample, and completes the blood sampling process, and the sampling port 6 on the constraint leaf 5 facilitates the staff to extract poultry blood from the outside through the blood sampling needle.

[0047] After the blood sample collection is completed, the operator manually pulls out the baffle 14 to make the frame opening 9 and the internal passage of the temporary storage cylinder 10 conductive; then the operator slightly shakes the restraint leaf 5, and utilizes the elastic properties of the restraint leaf 5 to not only avoid damaging the poultry, but also to frighten the poultry, so that the sympathetic nerves of the poultry respond quickly in the stress state to promote the excretion of feces; the feces fall on the two layers of screen plates 18 in the middle of the rotating ring 15 through the frame opening 9; the upper screen plate 18 has a hole diameter of 5 mm, and first filters the feathers, large feed residues and other impurities in the feces, and the remaining fecal particles fall on the lower screen plate 18; the lower screen plate 18 has a hole diameter of 2 mm, and further screens the fine impurities, and both the two layers of screen plates 18 are inclined downwardly towards the frame opening 9, so that the pure fecal sample after screening slides to the bottom of the temporary storage cylinder 10 along the screen plate 18 under the action of gravity, and each screen plate 18 is inclined downwardly, so that the screen holes on the surface of the screen plate are also in an inclined state to promote the fecal sample to slide quickly, and meanwhile, the slight centrifugal force generated by the synchronous rotation of the screen plate 18 with the rotating ring 15 further reduces the residue of the fecal sample on the screen surface; after the fecal sample collection is completed, the operator detaches the temporary storage cylinder 10 from the positioning disc 1, takes out the fecal sample at the bottom for packaging and marking, and completes the fecal sampling process.

[0048] After the fecal sample collection is completed, the first motor 16 is started in reverse rotation, the first motor 16 drives the gear 17 to rotate in reverse, the gear 17 engages with the gear ring 24 to drive the rotating ring 15 to rotate counterclockwise, the rotating ring 15 pushes the restraint leaf 5 outward through the hinged rod 7 to open the restraint leaf 5, and the restraint on the poultry is released, and the operator takes out the poultry after quarantine; then the baffle 14 is reinserted into the slot of the temporary storage cylinder 10 to block the passage of the frame opening 9; and the screw rod 3 is rotated to make the top disc 4 fall back to the initial position, and a new disposable blood sampling needle is replaced to prepare for the next quarantine sampling.

[0049] And the second motor 22 drives the worm 23 to rotate the sector tooth 20 to realize the function of adjusting the installation position of the device.

[0050] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
