Description

Technical Field

[0001] This utility model belongs to the technical field of laboratory animal cages, and in particular relates to a laboratory pig cage with compression and waste recycling functions. Background Technology

[0002] Experimental pig cages are important facilities used in scientific research for raising, managing, and studying experimental pigs. Their design must take into account animal welfare, ease of experimental operation, and data accuracy.

[0003] However, the cleaning of pig cages currently relies heavily on manual labor. Manual cleaning is not only time-consuming and labor-intensive, requiring frequent entry into the cages to bend over or squat, which can easily lead to operator fatigue and increase the risk of occupational injuries, but also the cleaning efficiency is limited by the amount of manpower required, making it difficult to meet the high-frequency cleaning needs of large-scale experimental pig farms. In terms of biosafety, manual operation can increase the risk of pathogen transmission due to contact with contaminated areas, especially during the critical period of infectious disease prevention and control. Personnel entering and leaving the cages may compromise the airtightness of the cages, leading to cross-contamination or deviations in experimental data. Utility Model Content

[0004] The purpose of this utility model is to address the current problem that the cleaning of pig cages relies heavily on manual labor. Manual cleaning is not only time-consuming and labor-intensive, requiring frequent entry into the cages for bending or squatting, which easily leads to operator fatigue and increases the risk of occupational injuries, but also limits cleaning efficiency due to manpower input, making it difficult to meet the high-frequency cleaning needs of large-scale experimental pig farms. In terms of biosafety, manual operation is prone to increasing the risk of pathogen transmission due to contact with contaminated areas, especially during critical periods of infectious disease prevention and control. Personnel entering and exiting may compromise the airtightness of the cages, leading to cross-contamination or deviations in experimental data. Therefore, this utility model proposes a laboratory pig cage with compression and waste recycling functions.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0024] 1. In this utility model, several second gear assemblies are arranged on the left and right sides of the pig cage frame, and the first gear assembly is located on the rear side of the pig cage frame. The first gear assembly and the second gear assembly are interconnected by a gear belt. By rotating the manual lever, the drive gear and the adapter gear mesh with each other, thereby driving the first gear assembly at the bottom rear side of the pig cage frame and the second gear assembly at the bottom sides to rotate. The rotation of the second gear assemblies on both sides will drive the second gear belt to rotate. When the second gear belt rotates, it will drive the gear belt on the left side of the pig cage frame to rotate, thereby moving the extrusion frame to the left and also driving the rear... The first gear assembly on the top side rotates, which drives the second gear assembly on the top right side of the pig cage frame to move, thereby moving the right side of the compression frame. This allows both sides of the compression frame to move synchronously within the pig cage frame, compressing and crushing the waste on the pig cage pedals. The waste then falls through the perforated holes in the pedals into the waste collection trough. When it is necessary to clean the waste in the waste collection trough, simply open the manual valve to let it fall into the waste collection bin, and then push the waste collection bin away. This allows for the collection of waste from animal cages in the laboratory without the need for manual entry for cleaning.

[0026] 3. In this utility model, an extrusion plate can also be set inside the extrusion frame to extrude the animal, which makes it easier to fix the animal and facilitates injection or sampling. The L-shaped pig feed box makes it easy to add feed and reduces interference to the animal. Attached Figure Description

[0051] Working Principle: Several second gear assemblies are arranged on the left and right sides of the pig cage frame, while the first gear assembly is located at the rear of the pig cage frame. The first and second gear assemblies are interconnected via gear belts. By rotating the manual lever, the drive gear and the adapter gear mesh, thereby driving the first gear assembly at the bottom rear of the pig cage frame and the second gear assemblies on both sides to rotate. The rotation of the second gear assemblies on both sides drives the second gear belt to rotate. When the second gear belt rotates, it drives the gear belt on the left side of the pig cage frame to rotate, thus moving the compression frame to the left. At the same time, it also drives the first gear assembly at the top rear to rotate. The rotation of the first gear assembly drives the second gear assembly at the top right side of the pig cage frame to move, thus moving the compression frame to the right. This allows the compression frame to move synchronously on both sides within the pig cage frame, crushing and grinding the waste on the pig cage pedal, causing it to fall into the waste collection trough through the perforations on the pig cage pedal. When it is necessary to clean the waste in the waste collection trough, simply open the manual valve to let it fall into the waste collection bin, and then push the waste collection bin away. This achieves waste collection from animal cages in the laboratory without the need for manual entry for cleaning.
