The extrusion grate 8 is movably connected to the cage body 1. Two parallel guide rails are installed on the top of the cage body 1 along the extrusion grate 8 toward the direction of the food box 12. The upper end of the extrusion grate 8 is fixedly connected with a guide block that cooperates with the guide rails. A moving screw 13 parallel to the guide rails is installed in the cage body 1, and the moving screw 13 is rotatably connected to the cage body 1. The moving screw 13 passes through the extrusion grate 8 and is threadedly connected to the extrusion grate 8. A first motor 131 is installed on the cage body 1, and the output shaft of the first motor 131 is coaxially fixedly connected to the moving screw 13. Start the first motor 131, and control the movable screw 13 to rotate by rotating the output shaft of the first motor 131. The movable screw 13 is rotated according to the body size of the experimental animal, and the extrusion grate 8 in the cage body 1 moves. The guide block moves along the guide rail, thereby improving the stability of the movement process of the extrusion grate 8 and facilitating the adjustment of the size of the internal space of the experimental cage.

[0042] Reference Figure 1The cage body 1 is provided with a valve assembly on both sides away from the food box 12. The valve assembly includes a fixed door 22 and a movable door 21. The fixed door 22 is located on the side close to the food box 12, and the movable door 21 is located on the side away from the food box 12. A movable guide rail for the movable door 21 to move is provided on the cage body 1, so that the cage body 1 can move toward the food box 12. A crescent lock 23 is installed between the fixed door 22 and the movable door 21. The crescent lock 23 facilitates the fixing and separation between the fixed plate and the movable door 21. The extrusion grate 8 is moved so that the extrusion grate 8 is located on the side of the cage body 1 away from the food box 12. The movable door 21 is opened and the experimental animal is placed in or taken out of the cage body 1.

[0043] Reference Figure 2 A lifting screw 14 is connected to the cage body 1 and rotates along the height direction. A lifting block 142 is passed through the lifting screw 14. A nipple drinker 143 is installed on the lifting block 142. The nipple drinker 143 is connected to a water supply pipe. A second motor 141 is installed above the cage body 1. When the second motor 141 is started, the lifting screw 14 rotates and the height of the nipple drinker 143 is adjusted according to the body size of the experimental animals to facilitate the experimental animals to drink water.

[0044] Reference Figure 2 and Figure 3 The bottom end of the cage 1 is a support net 15, and the cage 1 is equipped with a metabolic tray 3 located below the support net 15. The metabolic tray 3 is located above the support plate 11. A urine leakage hole 31 is opened on the side of the metabolic tray 3 close to the food box 12. A guide plate 32 is fixedly installed in the metabolic tray 3. The guide plate 32 is tilted downward from the end of the urine leakage hole 31 to the end close to the urine leakage hole 31. A blocking net 311 is installed above the urine leakage hole 31 on the metabolic tray 3. A metabolic collection tank 37 connected to the urine leakage hole 31 is installed below the metabolic tray 3 (refer to Figure 1 Metabolites of the experimental animals in the cage 1 fall through the mesh of the support net 15 onto the metabolic tray 3. The guide plate 32 is tilted so that urine falling onto the metabolic tray 3 moves along the guide plate 32 toward the urine leakage hole 31. The blocking net 311 blocks the feces, and urine enters the metabolic collection tank 37 through the urine leakage hole 31, making it easier to separate the excrement of the experimental animals.

[0045] Reference Figure 3 In the metabolic tray 3, inclined blocks 33 are respectively installed on both sides of the leakage hole, and the two inclined blocks 33 are arranged downwardly inclined from one end away from the urine leakage hole 31 to the end close to the urine leakage hole 31. The inclined blocks 33 guide the flow of urine and facilitate the urine to enter the urine leakage hole 31.

[0046] Reference Figure 3A filter plate 4 is provided in the metabolic tray 3 above the guide plate 32, with a gap for urine to pass between the filter plate 4 and the guide plate 32. The filter plate 4 blocks the feces on the guide plate 32, and the urine flows downward through the gap between the filter plate 4 and the guide plate 32.

[0047] Reference Figure 3 and Figure 4 The metabolic tray 3 has guide channels 34 on both sides of the sidewalls away from the urine leakage hole 31, which are parallel to the length of the guide plate 32. A limiting groove 341 is formed on the side of the metabolic tray 3 near the urine leakage hole 31. The limiting groove 341 is connected to the guide channel 34 and the connection position is located in the middle of the limiting groove 341. The metabolic tray 3 is movably mounted with a limiting block 3411 located below the limiting groove 341. The lower end of the limiting block 3411 is connected to a limiting spring 3412. The end of the limiting spring 3412 away from the limiting block 3411 is fixedly connected to the bottom of the limiting groove 341. When the limiting spring 3412 is in a natural state and the guide block 41 is located in the limiting groove 341 and abuts the limiting block 3411, a gap for urine to pass through is left between the filter plate 4 and the guide plate 32. When the guide block 41 is located in the guide channel 34, the lower end surface of the filter plate 4 is in contact with the upper end surface of the guide plate 32. The guide block is moved along the limiting groove 341 into the guide channel 34 , and the lower end surface of the filter plate 4 abuts against the upper end surface of the guide plate 32 . During the movement of the guide block along the guide channel 34 , the filter plate 4 moves above the guide plate 32 and scrapes off the feces on the guide plate 32 .

[0048] Reference Figure 5 and Figure 6 A scraper 6 is movably mounted on the side of the metabolic tray 3 away from the urine leakage hole 31. The lower end surface of the scraper 6 is in contact with the upper end surface of the guide plate 32. When the guide block 41 is located at the end of the guide channel 34 away from the limiting groove 341, the scraper 6 is in contact with the filter plate 4. A sliding groove 35 is horizontally provided on the side wall of the metabolic tray 3 near the scraper 6. A sliding plate 61 is fixedly connected above the scraper 6. The sliding plate 61 extends in the direction of the sliding groove 35 and is movably connected to the metabolic tray 3. A door 36 is provided on the side wall of the metabolic tray 3 near the cleaning plate 7, corresponding to the scraper 6. The door 36 is hinged to the metabolic tray 3. When the guide block moves to the end of the guide channel 34 away from the limiting groove 341, the scraper 6 moves along the length of the sliding groove 35, cleaning the feces on the filter plate 4 and the guide plate 32. The door 36 is opened, and the scraper 6 pushes the feces out of the door 36 and out of the metabolic tray 3 for collection and processing.

[0049] Reference Figure 5 and Figure 6A cleaning plate 7 is provided on one side of the scraper 6. The cleaning plate 7 is fixedly connected to the scraper 6 by a sliding plate 61. Brushes 71 are provided on the cleaning plate 7 near the guide plate 32 and the filter plate 4. A through hole is opened on the side wall of the metabolic tray 3 to communicate with the sliding groove 35. A pull rod 611 is fixedly connected to the sliding plate 61 along the length of the sliding groove 35. The end of the pull rod 611 away from the sliding plate 61 passes through the through hole. A pull ring 6111 is installed on the end of the pull rod 611 located on the metabolic tray 3. The pull ring 6111 facilitates the movement of the pull rod 611, allowing the scraper 6 and the cleaning plate 7 to move along the length of the sliding groove 35. The bristles 71 on the cleaning plate 7 first clean the feces on the filter plate 4 and the guide plate 32, and then the scraper 6 removes them, thereby improving the feces removal effect.

[0050] Reference Figure 7 The guide channel 34 is provided with a fixing component 5 for limiting the position of the guide block 41 at one end away from the limiting groove 341. The fixing component 5 includes a fixing block 51 and a fixing spring 52. The fixing block 51 is located in the fixing groove 342 and is movably connected to the metabolic tray 3. The two ends of the fixing spring 52 are fixedly connected to the fixing block 51 and the metabolic tray 3 respectively. When the fixing spring 52 is in a natural state, the fixing block 51 extends from the fixing groove 342 into the guide channel 34 to limit the guide block 41, preventing the filter plate 4 from moving due to gravity, thereby improving the stability of the scraper 6 in the process of scraping feces on the filter plate 4, and moving the fixing block 51 toward the fixing groove 342. The fixing spring 52 is compressed, and the fixing block 51 does not block the guide block 41, so that the guide block 41 passes through the guide channel 34 and returns to the limiting groove 341.

[0051] The implementation principle of the dual-purpose feeding and metabolism experimental cage of the embodiment of the present application is as follows: start the first motor 131, and control the movable screw 13 to rotate by rotating the output shaft of the first motor 131. The movable screw 13 is rotated according to the body size of the experimental animal, and the extrusion grate 8 in the cage body 1 moves. The guide block moves along the guide rail to improve the stability of the movement process of the extrusion grate 8, which facilitates the adjustment of the size of the internal space of the experimental cage. Start the second motor 141 to rotate the lifting screw 14, and adjust the height of the nipple waterer 143 according to the body size of the experimental animal to facilitate the experimental animal to drink water.
