[0029] Reference Figure 1 As shown, this utility model provides a technical solution: an automatic bedding replacement device for laboratory animals, including a cage 1 and an adjustment structure 3. A cage door 2 is installed on one side of the cage 1, the adjustment structure 3 is located on the inner wall of the cage 1, and a collection structure 4 is provided on the inner wall of the sludge collection box 313.

[0030] The specific settings and functions of its adjustment structure 3 and collection structure 4 will be discussed below.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the adjustment structure 3 includes a storage box 301 and a base box 304. The storage box 301 is fixed to the inner wall of the feeding cage 1. The lower surface of the storage box 301 is fixedly connected to a discharge pipe 302. A solenoid valve 303 is installed on the arc surface of the discharge pipe 302. The base box 304 is fixed to the bottom of the inner wall of the feeding cage 1. A discharge hole 305 is opened at the bottom of the inner wall of the base box 304. A lead screw 306 is rotatably connected to the inner wall of the base box 304. A welding plate 307 is fixedly connected to one side of the outer wall of the base box 304. A servo motor 308 is fixedly connected to one side of the welding plate 307. The output end of the servo motor 308 is fixedly connected to one end of the lead screw 306. A connecting plate 309 is threadedly connected to the arc surface of the lead screw 306. A guide rod 310 is slidably passed through the surface of the connecting plate 309. A scraper 311 is fixedly connected to the lower end of the guide rod 310. By setting the adjustment structure 3, the bedding material inside the feeding cage 1 can be automatically replaced without manual replacement, reducing the risk of contamination and ensuring the cleanliness of the bedding material. A positioning rod slides through the side of the connecting plate 309 and is fixed to the inner wall of the base box 304. When the lead screw 306 drives the connecting plate 309 to move, the connecting plate 309 moves along the arc surface of the positioning rod, thereby improving the stability of the connecting plate 309's movement. An electric actuator 312 is fixedly connected to the upper surface of the connecting plate 309, and the output end of the electric actuator 312 is fixedly connected to the upper surface of the scraper 311. Activating the electric actuator 312 can drive the scraper 311 to move, thereby automatically adjusting the height of the scraper 311. A sludge collection box 313 is fixedly connected to the lower surface of the base box 304, and the interior of the sludge collection box 313 is connected to the discharge hole 305. The sludge collection box 313 can collect the bedding material discharged from the discharge hole 305, thereby preventing the bedding material from contaminating the surrounding environment.

[0032] Reference Figure 4 and Figure 5As shown in this embodiment: the collection structure 4 includes a collection box 41, which is placed inside the sludge collection tank 313. Sliding holes 43 are provided on both sides of the sludge collection tank 313. A sliding rod 44 is slidably connected to the inner wall of the sliding hole 43. An adjusting ring 45 is threadedly connected to the arc surface of the sliding rod 44. Several anti-slip patterns 47 are evenly distributed on the outer wall of the adjusting ring 45. By setting up the collection structure 4, the collection box 41 can collect used bedding material, and personnel can easily transfer the collection box 41, thus facilitating the unified disposal of waste bedding material. A handle 42 is fixedly connected to one side of the outer wall of the collection box 41. The handle 42 has a "U" shaped cross-section. Moving the handle 42 can drive the collection box 41, achieving convenient control of the collection box 41. A rubber pad 46 is fixedly connected to the side of the adjusting ring 45 near the sludge collection tank 313. The diameter of the rubber pad 46 is larger than the diameter of the adjusting ring 45. The rubber pad 46 can increase the friction of the adjusting ring 45 on the side near the sludge collection box 313, so that the adjusting ring 45 can be more firmly abutted against the sludge collection box 313 with the help of the rubber pad 46.

[0033] Working principle: The bedding material in the experimental animal cage 1 is a special material used to absorb excrement, keep the cage dry and clean, and improve animal comfort. When it is necessary to replace the bedding material at the bottom of the inner wall of the base box 304, the servo motor 308 is started to drive the lead screw 306 to rotate. The lead screw 306 drives the connecting plate 309, which in turn drives the guide rod 310 and the scraper 311. The scraper 311 moves along the bottom of the inner wall of the base box 304. During the movement of the scraper 311, it pushes the bedding material on the inner wall of the base box 304. The bedding material is pushed into the discharge hole 305 by the scraper 311 and finally falls into the sludge collection box 313. The above steps are repeated. The process continues until the padding material is completely scraped off. After the above steps are completed, the solenoid valve 303 is opened, allowing the padding material inside the storage box 301 to fall onto the inner wall of the base box 304 along the discharge pipe 302. Then, the servo motor 308 is started to run, causing the scraper 311 to move along the inner wall of the base box 304 and flatten the padding material on the inner wall of the base box 304. During the flattening process, the electric push rod 312 can be activated to drive the scraper 311 and adjust the height of the scraper 311, thereby flattening the padding material to different heights. The sludge collection box 313 can collect the padding material discharged from the discharge hole 305, thereby preventing the padding material from polluting the surrounding environment.

[0034] During the operation of the adjustment structure 3, the bedding material falling into the sludge collection box 313 from the discharge hole 305 will be collected by the collection box 41. When the collection box 41 is full and the waste bedding material inside needs to be dumped, first use the anti-slip texture 47 to rotate the adjustment ring 45, so that the adjustment ring 45 drives the rubber pad 46 to separate from the outer wall of the sludge collection box 313. At this time, the limit on the collection box 41 can be released. Then move the handle 42 to drive the collection box 41, so that the collection box 41 drives the sliding rod 44 to separate from the sliding hole 43. After the sliding rod 44 separates from the sliding hole 43, the disassembly of the collection box 41 can be completed, and then personnel can move the collection box. The collection box 41 is used to transfer and empty the bedding material inside. After the bedding material is emptied, the collection box 41 is moved and placed into the inner wall of the sludge collection tank 313. At the same time, the sliding rod 44 is inserted into the sliding hole 43. After the collection box 41 is placed in its original position, the adjusting ring 45 is rotated with the help of the anti-slip texture 47, so that the adjusting ring 45 drives the rubber pad 46 to abut against the outer wall of the sludge collection tank 313, thus completing the installation of the collection box 41. The rubber pad 46 can increase the friction of the adjusting ring 45 near the sludge collection tank 313, so that the adjusting ring 45 can abut against the sludge collection tank 313 more firmly with the help of the rubber pad 46.
