[0002] Infectious bursal disease (IBD) is a common disease in chickens caused by the infectious bursal virus (IBDV). Chickens with the disease will experience reduced weight gain, death, severe dehydration, and skeletal muscle bleeding, making it highly harmful to the poultry industry. In order to diagnose the disease in sick chickens, it is necessary to obtain the bursa and spleen from the sick chickens, grind the bursa and spleen into a suspension, centrifuge the suspension, and finally obtain the supernatant for pathological analysis. At present, after the suspension is centrifuged, the supernatant needs to be transferred manually with a handheld pipette. When multiple typical sick chickens in the same farm are diagnosed at the same time, the separation efficiency of the supernatant is relatively low. Utility Model Content

[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0031] Please refer to Figure 1 as well as Figure 2 A rapid separation device for chicken bursa of Fabricius comprises a lifting mechanism 1, a supporting assembly 2 and a liquid extraction mechanism 3; at least two supporting assemblies 2 are arranged at the movable end of the lifting mechanism 1, the liquid inlet end of the liquid extraction mechanism 3 is coaxially arranged with the supporting assembly 2, and the supporting assembly 2 is used to place a centrifuge tube 4; the lifting mechanism 1 is slidably connected with the liquid extraction mechanism 3 so that the liquid inlet end of the liquid extraction mechanism 3 can be inserted into the centrifuge tube 4; a sensing assembly 5 is respectively arranged on both sides of the length direction of the liquid extraction mechanism 3, and the sensing assembly 5 is arranged opposite to the liquid inlet end of the liquid extraction mechanism 3. Preferably, two supporting assemblies 2 are arranged.

[0032] It is understandable that, due to the setting of the sensing component 5, it can sense whether the lifting position of the lifting mechanism 1 is in place and whether the height of the lifting mechanism 1 needs to be adjusted. The lifting mechanism 1 drives the support component 2 to rise and fall, so that the liquid inlet end of the extraction mechanism 3 can be inserted into the centrifuge tube 4 placed on the support component 2 to extract the supernatant, ensuring that the extraction mechanism 3 can extract enough supernatant. The utility model can quickly extract the supernatant after centrifugation, and can extract the supernatant from multiple centrifuge tubes 4 at the same time, realizing batch processing and improving the separation efficiency of the supernatant.

[0033] In this embodiment, in the moving direction of the lifting mechanism 1, the distance between the horizontal plane where the sensing end of the sensing component 5 is located and the horizontal plane where the liquid inlet end of the pumping mechanism 3 is located is 0.1cm~0.8cm. Preferably, the distance is 0.7cm. The sensing component 5 is used to sense whether the lifting height of the lifting mechanism 1 is in place and to sense the turbidity of the liquid to determine the lowest liquid level of the supernatant, thereby controlling the lifting height of the lifting mechanism 1.

[0034] In this embodiment, the lifting mechanism 1 includes a lifting plate 11 and a driving member 12; the lifting plate 11 is provided with a through hole for the centrifuge tube 4 to pass through, and the lifting plate 11 is in transmission connection with the driving member 12; the support assembly 2 is arranged on the side of the lifting plate 11 away from the liquid inlet end of the liquid extraction mechanism 3. The setting of the support assembly 2 is used to support and limit the centrifuge tube 4. Preferably, the driving member 12 is a linear cylinder.

[0035] In this embodiment, a baffle 13 is provided on the lifting plate 11, and two sensing components 5 can be respectively arranged opposite to the two sides of the baffle 13. Specifically, the sensing component 5 is a turbidity sensor, and the sensing component 5 has a receiving end and a light-emitting end. The receiving end of the sensing component 5 is arranged on the baffle 13, and the light-emitting end of the sensing component 5 is arranged on the lifting mechanism 1, and the light-emitting end of the sensing component 5 is arranged opposite to the receiving end of the sensing component 5.

[0036] In this embodiment, the liquid pumping mechanism 3 includes a bracket 31 and a liquid inlet assembly 32; the liquid inlet assembly 32 is detachably mounted on the top of the bracket 31 and is arranged opposite to the lifting mechanism 1. Specifically, the liquid inlet assembly 32 includes a liquid pumping cylinder 321, a cover 322 and a check valve 323; the liquid outlet end of the liquid pumping cylinder 321 is detachably connected to the cover 322, and the liquid pumping cylinder 321 is connected to the negative pressure device through the cover 322; the check valve 323 is installed at the liquid inlet end of the liquid pumping cylinder 321. The negative pressure adsorption device is connected to the inner cavity of the liquid pumping cylinder 321 through the cover 322, so that the supernatant is transferred from the centrifuge tube 4 to the liquid pumping cylinder 321 under the action of negative pressure. When the liquid pumping is completed, the cover 322 is separated from the liquid pumping cylinder 321. At this time, the setting of the check valve 323 can prevent the liquid from flowing back, thereby facilitating the liquid pumping cylinder 321 to transfer the supernatant.

[0037] In this embodiment, the liquid extraction cylinder 321 includes a cylinder 3211 and a needle 3212; the cylinder 3211 is detachably connected to the bracket 31; the needle 3212 and the cover 322 are respectively connected to the two ends of the cylinder 3211, and the needle 3212 can be inserted into the centrifuge tube 4. The cylinder 3211 is detachably connected to the bracket 31 to facilitate the transfer of supernatant and the cleaning of the cylinder 3211.

[0038] In this embodiment, the bracket 31 includes a top plate 311, a bottom plate 312 and at least two guide rods 313; the top plate 311 and the bottom plate 312 are connected by the guide rods 313; the lifting plate 11 of the lifting mechanism 1 is slidably connected to the guide rods 313 to improve the stability of the lifting plate 11. Preferably, two guide rods 313 are provided, and the light-emitting end of the sensing component 5 is provided on the guide rods 313.

[0039] The working principle of the utility model is:

[0040] In the initial state, the driving member 12 is in a retracted state;

[0041] Place the centrifuge tube 4 after centrifugation in the corresponding support assembly 2, and connect the cover 322 to the liquid extraction cylinder 321;

[0042] The switch is turned on manually, the driving member 12 extends, and after the light-emitting end of the sensing component 5 is aligned with the receiving end, the driving member 12 stops moving, and determines whether the driving member 12 needs to be lowered according to the turbidity signal of the sensing component 5. If the detection result of the sensing component 5 is greater than the preset value, but the difference is within the set value range, the lifting mechanism 1 is controlled to descend to the preset height. If the detection result of the sensing component 5 is less than or equal to the preset value, the lifting mechanism 1 remains stationary.

[0043] After the lifting mechanism 1 is adjusted into place, the negative pressure adsorption device is started, and the supernatant is sucked into the liquid extraction cylinder 321. After the supernatant is sucked, the cover body 322 is separated from the liquid extraction cylinder 321, the liquid extraction cylinder 321 is transferred, and a clean liquid extraction cylinder 321 is replaced for the next extraction.

[0044] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
