Description

Technical Field

[0001] The utility model belongs to the technical field of vaccine production equipment, and particularly relates to an isolator with an automatic chicken feces sampling function. Background Technique

[0002] In the production cycle of vaccines, SPF animals are usually used. SPF (Specific Pathogen Free) animals refer to animals without specific pathogens, that is, experimental animals that do not carry the main potential infections or conditional pathogens that are harmful to scientific experiments and interfere greatly with scientific experiments, in addition to the pathogens that should be excluded from clean animals. In the production cycle of vaccines, chickens are usually used as experimental subjects.

[0003] Isolators are usually used for the inspection of SPF animals. In these inspection procedures, the isolator provides a certain isolation space for SPF animals, and the inspection personnel perform inspection operations on SPF animals through isolation gloves to avoid adverse effects of the operator's own hair, sweat, etc. on the inspection conclusion. Another function of the isolator is to treat and discharge the waste gas generated during the inspection process to avoid the entry of pathogenic microorganisms that may be contained in the waste gas into the surrounding environment and cause pollution.

[0004] When using an isolator for feeding experiments on SPF animals, it is often necessary to sample the feces produced by the SPF animals. Animal feces sampling is the process of collecting and analyzing animal feces samples. Animal feces inspection can provide important information about animal health, nutrition, drug treatment, and environmental quality, helping experimental personnel make scientific judgments and decisions. However, the existing traditional isolators do not have an automatic feces collection function. Experimental personnel need to manually collect the feces through isolation gloves using simple tools such as scrapers and brushes. The operation process is cumbersome, which also increases the labor intensity of the staff. In addition, during the collection process, another staff member is required to control the SPF animals in the isolator to avoid the activities of the SPF animals affecting the feces collection process or even biting the experimental personnel, resulting in poor safety. Therefore, it is urgent to design an isolator with an automatic chicken feces sampling function to solve the above problems. Content of the Utility Model

[0005] The utility model provides an isolator with an automatic chicken feces sampling function and a reasonable structural design to solve the technical problems existing in the known technology. The utility model can automatically collect the feces produced by experimental animals in the isolator. The operation process is simple and convenient, without the need for manual collection by staff, with low labor intensity and strong safety.

[0006] The technical solution adopted by the present utility model to solve the technical problems existing in the known technology is as follows: An isolator with an automatic chicken manure sampling function includes a mounting bracket, on which an isolation box body is mounted. An air inlet and outlet purification device and a transfer window are mounted on the isolation box body. A collection base structure is mounted at the bottom of the isolation box body. A hollow partition structure is mounted in the middle area of the collection base structure. A lift plate structure that can be lifted and moved is inserted and matched on the hollow partition structure. A lifting drive device for driving the lift plate structure to lift and move is mounted on the collection base structure. A cleaning device is also mounted on the collection base structure, which is used to clean the hollow partition structure when the lift plate structure is lifted to the highest position. A through groove is opened on the side surface of the collection base structure, and a collection box is inserted through the through groove for receiving the manure cleaned by the cleaning device. A collection sealing window corresponding to the collection box is arranged at the lower part of the side surface of the isolation box body.

[0007] The advantages and positive effects of the present utility model are as follows: The present utility model provides an isolator with an automatic chicken manure sampling function. By setting a hollow partition structure and a lift plate structure that are inserted and matched, and cooperating with a lifting drive device for driving the lift plate structure to lift and move, the lift plate structure can be lifted when manure sampling is required, thereby lifting the experimental animals upward, avoiding the influence of the experimental animals on the manure sampling process, and preventing the experimental animals from biting the staff, with strong safety. By setting a cleaning device, when the lift plate structure is lifted to the highest position, the manure attached to the hollow partition structure in a hollow state can be automatically cleaned, so that the cleaned manure automatically falls into the collection box, thereby realizing the automatic collection and sampling process of the manure. The operation process is simple and convenient, without the need for experimental personnel to manually clean and collect, reducing the labor intensity.

[0027] Working principle:

[0028] Experimental animals (such as experimental chickens) are raised in the isolation box body 7 for test observation and detection. When it is necessary to collect the feces produced by the experimental animals, the lifting motor 2-1 in the lifting drive device 2 is started, driving the lifting lead screw 2-2 installed thereon to rotate, and then lifting the lifting plate body 3-3 by a preset distance, so that the square hole 3-4 in the lifting plate structure 3 is disengaged from the corresponding square convex block 6-3 in plug-in fit, and ensuring that there is a space between the lifting plate structure 3 and the hollow partition structure 6 for the transverse mounting plate 5-4 and the cleaning brush 5-3 to move horizontally.

[0029] Then, the cleaning motor 5-1 in the cleaning device 5 is started.

During this cleaning process, the feces attached to the hollow partition structure 6 are swept off by the cleaning brush 5-3 and fall onto the guide cover 4-3 through the respective cleaning gaps 6-4, and then slide down the guide cover 4-3 into the collection box 1 for collection; after the above collection operation is completed, the two groups of rotating cleaning lead screws 5-2 drive the cleaning brush 5-3 and the transverse mounting plate 5-4 to reset to the recessed groove 4-4 extending along the width direction of the base box 4-2. The lifting motor 2-1 is started again, driving the lifting plate structure 3 to descend and reset to the position in plug-in fit with the hollow partition structure 6; then, the collection sealing window 10 on the isolation box body 7 is opened, and the collection box 1 is taken out for subsequent inspection operations.
