[0062] The core of this application is to provide a breeding squirrel cage, which facilitates the breeding personnel to transfer the mice in the cage and improves the cage replacement efficiency.

[0063] Another core of this application is to provide a cage - changing device using the breeding squirrel cage, which realizes automatic cage replacement, reduces the use of manpower, and improves the cage replacement efficiency.

[0064] To enable those skilled in the art of this technology to better understand the solution of this invention, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific implementation manners.

[0065] See Figures 1 - 3, a breeding mouse cage provided by the present application includes: a cage body 1, which is square. An outlet 11 is provided at the front end of the cage body 1, and a lifting door assembly 12 is arranged outside the outlet 11. The lifting door assembly 12 realizes the closing or opening of the outlet 11. Limiting plates 13 are symmetrically arranged on the left and right outer walls of the cage body 1, and the two limiting plates 13 are perpendicular to the outer wall of the cage body 1. The limiting plates 13 extend along the length direction of the cage body 1; a grille 2 is arranged inside the cage body 1. A concave grille 21 is provided at the end of the grille 2. The concave grille 21 is located at the bottom of the grille 2, and the lower surface of the concave grille 21 is attached to the bottom wall of the cage body 1. Feed is placed in the concave grille 21; a cage cover 3 is detachably connected to the top end of the cage body 1, and a life window 31 is arranged at the upper end of the cage cover 3, and an air inlet 32 and an air outlet 33 are arranged on one side wall at one end.

[0066] Through the breeding mouse cage provided by the present application, when the mice in the mouse cage need to be replaced into a clean mouse cage, by opening the lifting door assembly 12, the outlet 11 is opened, so that the mice can move through the outlet 11 into the clean mouse cage, and the replacement of the mouse cage can be completed.

[0067] That is to say, the air inlet 32 is connected to the air inlet system through a pipeline, and the air outlet 33 is connected to the air outlet system through a pipeline. The air inlet system and the air outlet system are both prior arts. When the mouse cage is replaced, the air inlet system and the air outlet system are disconnected from the air inlet 32 and the air outlet 33 respectively. Through the life window 31 arranged at the upper end, it is possible to prevent mice from suffocating. The life window 31 is composed of a plurality of through holes, and filter paper is arranged on the surface of the through holes, so as to achieve the effect of purifying the air.

[0068] In some embodiments, the front end face and the rear end face of the cage body 1 can be symmetric inclined faces, and the inclination angle range is from 3 degrees to 10 degrees, preferably 5 degrees. That is to say, the width between the two outer walls of the cage body 1 gradually increases from bottom to top, and thus the cross-sectional shape of the cage body 1 is trapezoidal. The setting of this inclination angle ensures that when the mouse cage is replaced, mice will not run out through the gap; wherein, buckles are installed on both the front and rear sides of the cage cover 3, and card seats are installed on the top of the front and rear sides of the cage body 1. The buckles are snap-connected with the card seats. Through the cooperation of the buckles and the card seats, it is convenient to detachably fix the cage cover 3 on the cage body 1. The grille 2 and the concave grille 21 are both aluminum alloy grilles, which reduce the weight of the cage while ensuring the hardness of the grille 2 and the concave grille 21, and are convenient for experimenters to move the mouse cage.

[0069] In some embodiments, the lifting door assembly 12 includes a chute 121, an annular gasket 122, and a door stopper 123. Among them, the chutes 121 are symmetrically arranged on the left and right sides of the outlet 11. The door stopper 123 is slidably installed in the chute 121. A door handle 124 is provided on the outer side of the bottom of the door stopper 123. The door handle 124 is an L-shaped plate, which is vertically fixed to the outer side of the bottom of the door stopper 123, and the formed notch faces upward. The door handle 124 enables the door stopper 123 to reciprocate in the chute 121. The annular gasket 122 is provided on the outer edge of the outlet 11, and the annular gasket 122 is attached to the inner side of the door stopper 123, that is, the annular gasket 122 is located between the door stopper 123 and the cage body 1. The material of the annular gasket 122 is silicone material.

[0070] That is to say, in this application, the door handle 124 enables the door stopper 123 to reciprocate in the chute 121, that is, to open or close the outlet 11. Since the annular gasket 122 of this application is provided on the outer edge of the outlet 11 and is attached to the inner side of the door stopper 123, when the door stopper 123 completely blocks the outlet 11, due to the interference of the annular gasket 122, it is further avoided that the door stopper 123 slides downward under its own gravity. That is, the use of the annular gasket 122 realizes the fixation of the door stopper 123 relative to the cage body 1 and completes the sealing of the mouse cage. Since the silicone has a large coefficient of friction, it further ensures that the door stopper 123 is more firmly fixed to the cage body 1.

[0071] A cage-changing device is applied to the above-mentioned breeding mouse cage. The cage-changing device includes: a loading device for storing a first mouse cage 14 with mice and a clean second mouse cage 15. The first mouse cage 14 and the second mouse cage 15 have the same structure, which is the above-mentioned breeding mouse cage; a cage-changing workstation 4 for transferring the mice in the first mouse cage 14 into the clean second mouse cage 15 to improve the breeding environment of the mice.

[0072] Based on the above embodiments, the loading device includes: a loading vehicle 111. Specifically, the loading vehicle 111 includes a first loading vehicle 1111, a second loading vehicle 1112, a third loading vehicle 1113, and a fourth loading vehicle 1114. The first loading vehicle 1111 and the third loading vehicle 1113 are located at the rear side of the lower box body 43, and the second loading vehicle 1112 and the fourth loading vehicle 1114 are located at the front side of the lower box body 43. The first loading vehicle 1111 is used to place the first mouse cage 14 in which mice are raised. The second loading vehicle 1112 is used to place the clean second mouse cage 15. The third loading vehicle 1113 is used to place the cage cover 3, the grille 2, and the cage body 1 after the replacement of the first mouse cage 14 is completed. The fourth loading vehicle 1114 is used to place the second mouse cage 15 in which mice are raised; a handling vehicle 112, which is used to move the loading vehicle 111. The handling vehicle 112 is an AGV intelligent handling vehicle and is directly used in the prior art. For example, when the third loading vehicle 1113 and / or the fourth loading vehicle 1114 are full, the handling vehicle 112 realizes the transfer of the third loading vehicle 1113 and the fourth loading vehicle 1114 to a designated position.

[0073] Based on the above embodiments, the cage-changing workstation 4 includes:

[0074] an upper box body 41, a support column 42, and a lower box body 43. The upper box body 41 is fixed above the lower box body 43 through the support column 42. Specifically, the support columns 42 are symmetrically arranged at the edges of the upper box body 41 in the front and rear. In the middle of the upper end of the lower box body 43, a first limit groove 411 and a second limit groove 412 are symmetrically arranged. The first limit groove 411 and the second limit groove 412 have the same structure and are both square grooves. The first limit groove 411 and the second limit groove 412 are located on the same axis, and there is a certain gap between the first limit groove 411 and the second limit groove 412;

[0075] A first manipulator 44 is arranged on the right side of the lower box body 43 and is close to the first limit groove 411. A second manipulator 45 is arranged on the left side of the lower box body 43 and is close to the second limit groove 412. Therefore, the first manipulator 44 and the second manipulator 45 are arranged diagonally with respect to the lower box body 43. The first manipulator 44 transfers the first mouse cage 14 located on the first loading vehicle 1111 into the first limit groove 411, and the second manipulator 45 transfers the second mouse cage 15 located on the second loading vehicle 1112 into the second limit groove 412, and the outlet 11 of the first mouse cage 14 faces the outlet 11 of the second mouse cage 15, that is, the outlet 11 of the first mouse cage 14 and the outlet 11 of the second mouse cage 15 are arranged opposite to each other;

[0076] The fixing device 5 is symmetrically arranged before and after in the lower box body 43. The fixing device 5 is used to fixedly position the cages 1 of the first rat cage 14 and the second rat cage 15 on the lower box body 43 on the first limiting groove 411 and the second limiting groove 412 respectively. When the cage 1 of the first rat cage 14 is fixed on the first limiting groove 411, the first manipulator 44 transfers the cage cover 3 and the grille 2 of the first rat cage 14 to the third loading vehicle 1113.

[0077] The transfer frame assembly is arranged in the lower box body 43 and can reciprocate vertically in the lower box body 43. The transfer frame assembly includes a transfer frame 6. When the transfer frame 6 is in the first position, the two ends of the transfer frame 6 are respectively communicated with the outlets 11 of the first rat cage 14 and the second rat cage 15. Specifically, the two ends of the transfer frame 6 are correspondingly attached to the outlets 11 of the first rat cage 14 and the second rat cage 15 to form a transfer channel.

[0078] The door opening device 7 is symmetrically arranged in the lower box body 43. The door opening device 7 is used to move the blocking doors 123 of the first rat cage 14 and the second rat cage 15 on the lower box body 43 to open or close the outlets 11 of the first rat cage 14 and the second rat cage 15.

[0079] The driving device 8 is arranged on the upper box body 41. The driving device 8 is used to drive the rats in the first rat cage 14 on the lower box body 43 into the second rat cage 15.

[0080] The heat sensing device 9 is arranged on the rear side column 42. The heat sensing device 9 is used to detect whether there are rats in the first rat cage 14 in the first limiting groove 411. When the heat sensing device 9 detects that there are rats in the first rat cage 14, the driving device 8 drives the rats in the first rat cage 14 into the second rat cage 15 again. When the heat sensing device 9 does not detect rats in the first rat cage 14, the door opening device 7 closes the outlet 11 of the second rat cage 15.

[0081] The disinfection device 10 is arranged on the column 42 and the upper box body 41. The disinfection device 10 is used to disinfect the first manipulator 44, the second manipulator 45 and the driving device 8.

[0082] The controller is respectively connected to the first manipulator 44, the second manipulator 45, the fixing device 5, the transfer frame 6, the door opening device 7, the driving device 8, the heat sensing device 9 and the disinfection device 10. The controller is a programmable logic controller.

[0083] Based on the above embodiments, the depths of the first limiting groove 411 and the second limiting groove 412 are both one-fifth of the height of the cage body 1, so as to realize that the outlet 11 of the first rat cage 14 located in the first limiting groove 411 and the outlet 11 of the second rat cage 15 located in the second limiting groove 412 are both above the upper surface of the lower box body 43, which is convenient for the rats in the first rat cage 14 to transfer into the second rat cage 15; the lengths of the first limiting groove 411 and the second limiting groove 412 are 1-3 mm greater than the length of the cage body 1, and the widths of the first limiting groove 411 and the second limiting groove 412 are 1-3 mm greater than the width of the cage body 1, so as to realize that the cage body 1 can be fitted and arranged in the first limiting groove 411 and the second limiting groove 412 to prevent the cage body 1 from shaking in the first limiting groove 411 and the second limiting groove 412.

[0084] Based on the above embodiments, the fixing devices 5 symmetrically arranged before and after in the lower box body 43 have the same structure. The fixing device 5 arranged at the rear end is used to fix the cage body 1 of the first rat cage 14 located on the lower box body 43 on the first limiting groove 411, and the fixing device 5 arranged at the front end is used to fix the cage body 1 of the second rat cage 15 located on the lower box body 43 on the second limiting groove 412. In this embodiment, the fixing device 5 arranged at the rear end will be specifically described. The fixing device 5 includes:

[0085] A first vertical guide rail 51 fixedly arranged in the lower box body 43, and a first slider 52 reciprocally moving on the first vertical guide rail 51; a first horizontal guide rail 53 is horizontally fixedly arranged on the right side surface of the first slider 52, and the length direction of the first horizontal guide rail 53 is perpendicular to the length direction of the first limiting groove 411. A second slider 54 and a third slider 55 are arranged on the first horizontal guide rail 53, and the second slider 54 and the third slider 55 slide close to or away from each other on the first horizontal guide rail 53. That is to say, the second slider 54 and the third slider 55 slide close to each other on the first horizontal guide rail 53, or the second slider 54 and the third slider 55 slide away from each other on the first horizontal guide rail 53;

[0086] A first rat cage pressing plate 56 is vertically fixedly arranged on the upper surface of the second slider 54, a second rat cage pressing plate 57 is vertically fixedly arranged on the upper surface of the third slider 55, a pressing plate is arranged on the upper right side of the upper end of the first rat cage pressing plate 56, a pressing plate is arranged on the upper left side of the upper end of the second rat cage pressing plate 57, and the first rat cage pressing plate 56 and the second rat cage pressing plate 57 are located on both sides of the first limiting groove 411.

[0087] That is to say, when the first squirrel cage 14 is placed on the first limiting groove 411, the first slider 52 rises to a certain height, the second slider 54 slides leftward by a certain distance, and the third slider 55 slides rightward by a certain distance. That is, the second slider 54 and the third slider 55 slide closer. At this time, the first squirrel cage pressing plate 56 is directly above the right limiting plate 13 of the first squirrel cage 14, and the second squirrel cage pressing plate 56 is directly above the left limiting plate 13 of the first squirrel cage 14. Then the first slider 52 descends to a certain height. At this time, the first squirrel cage pressing plate 56 presses on the right limiting plate 13 of the first squirrel cage 14, and the second squirrel cage pressing plate 57 presses on the left limiting plate 13 of the first squirrel cage 14, thereby completing the fixation of the cage body 1 of the first squirrel cage 14. Similarly, the fixing device 5 provided at the front end completes the fixation of the cage body 1 of the second squirrel cage 15. After the fixation of the cage body 1 of the first squirrel cage 14 is completed, it is convenient for the first manipulator 44 to transfer the cage cover 3 and the grille 2 of the first squirrel cage 14 to the third loading vehicle 1113. And since the fixing device 5 is connected to the controller, the moving paths of the first slider 52, the second slider 53, and the third slider 54 have been edited by the controller. Therefore, the moving paths of the first slider 52, the second slider 53, and the third slider 54 are not described in detail in this embodiment.

[0088] Based on the above embodiment, the door opening devices 7 symmetrically arranged in the lower box body 43 have the same structure. Specifically, the door opening devices 7 are symmetrically arranged front and back in the lower box body 43. The door opening device 7 provided at the front end realizes the reciprocating movement of the blocking door 123 of the second squirrel cage 15, thereby realizing the opening or closing of the outlet 11 of the second squirrel cage 15. Therefore, the door opening device 7 provided at the front end is located directly below the outlet 11 of the second squirrel cage 15. The door opening device 7 provided at the rear end realizes the reciprocating movement of the blocking door 123 of the first squirrel cage 14, thereby realizing the opening or closing of the outlet 11 of the first squirrel cage 14.

Specifically, the second vertical guide rail 73 is inclined on the upper surface of the fourth slider 72, and the inclination angle of the second vertical guide rail 73 is the same as the inclination angle of the front end face of the cage body 1 of the first squirrel cage 14. A fifth slider 74 moving reciprocally is arranged on the second vertical guide rail 73. A push-pull door rod 75 is fixedly arranged on the upper surface of the fifth slider 74. Since the extending direction of the push-pull door rod 75 is parallel to the extending direction of the second vertical guide rail 73, the inclination angle of the push-pull door rod 75 is the same as the inclination angle of the second vertical guide rail 73. A groove 751 is provided at the front end of the push-pull door rod 75, and the groove 751 is used to cooperate with the door handle 124 to realize the reciprocating movement of the door handle 124.

[0090] That is to say, the fourth slider 72 slides a certain distance to the right and the fifth slider 74 slides a certain distance upward, so that the groove 751 is arranged opposite to the door handle 124. Then, the fourth slider 72 slides a certain distance to the left to engage the groove 751 with the door handle 124. Next, the fifth slider 74 slides a certain distance upward to fully open the door stopper 123, and then the outlet 11 of the first rat cage 14 is fully opened. Moreover, since the door opening device 5 is connected to the controller, the moving paths of the fourth slider 72 and the fifth slider 74 have been edited by the controller. Therefore, the moving paths of the fourth slider 72 and the fifth slider 74 will not be described in detail in this embodiment.

[0091] Based on the above embodiments, the driving device 8 of the present application includes a fixed frame 81. The fixed frame 81 is square, and the length, width, and height of the fixed frame 81 are 0 - 1 mm less than the length, width, and height of the cage body 1 of the rat cage 1. The bottom of the fixed frame 81 is provided with an opening, and through holes are provided at the front and rear ends. The fixed frame 81 is located directly above the first limiting groove 411, and the fixed frame 81 can be placed in the cage body 1 of the first rat cage 14 by means of a moving component 82. When the fixed frame 81 is inside the cage body 1, the through holes of the fixed frame 81 are opposite to the outlet 11 of the cage body 1; a driving member 83 is fitted inside the fixed frame 81, and an elastic member 84 is arranged between the driving member 83 and the fixed frame 81. The driving member 83 can reciprocate inside the fixed frame 81 by means of the moving component 82.

[0092] That is to say, when the outlets 11 of both the first rat cage 14 and the second rat cage 15 are opened, the fixed frame 81 is closely arranged inside the cage body 1 of the first rat cage 14. Since the bottom of the fixed frame 81 is provided with an opening, the rats in the first rat cage 14 are located inside the fixed frame 81. Then, the through holes provided in the fixed frame 81 are in communication with the outlet 11 of the cage body 1 of the first rat cage 14. Since a reciprocating driving member 83 is arranged inside the fixed frame 81, by means of the driving member 83, the rats inside the fixed frame 81 are driven to the position of the outlet 11 of the first rat cage 14, thus realizing driving the rats in the first rat cage 14 into the second rat cage 15. Since an elastic member 84 is arranged between the driving member 83 and the fixed frame 81, and the elastic member 84 can specifically be a spring, during the movement of the driving member 83, the elastic member 84 plays a buffering role to prevent the driving member 83 from exerting excessive force and causing injury to the bred rats.

[0093] Based on the above embodiments, third vertical guide rails 821 are symmetrically arranged on the upper box body 41. Sixth sliders 822 are slidably arranged on both of the third vertical guide rails 821. A transverse connecting rod 823 is arranged between the two sixth sliders 822. The left and right ends of the bottom of the transverse connecting rod 823 are symmetrically provided with first vertical connecting rods 824. The bottom ends of the two first vertical connecting rods 824 are connected to the fixed frame 81. A longitudinal guide rail 825 is fixedly arranged on the lower surface of the transverse connecting rod 823. The longitudinal guide rail 825 is perpendicular to the transverse connecting rod 823 by 90 degrees. A seventh slider 826 is slidably arranged at the bottom of the longitudinal guide rail 825. A second vertical connecting rod 827 is arranged at the bottom of the seventh slider 826. The bottom of the second vertical connecting rod 827 is connected to the driving member 83.

[0094] That is to say, when the sixth slider 822 slides vertically downward on the third vertical guide rail 821, it drives the first vertical connecting rod 824 to move vertically downward. Since the first vertical connecting rod 824 is connected to the fixed frame 81, the fixed frame 81 is made to fit and place inside the cage body 1 of the first rat cage 14. Since the seventh slider 826 can slide at the bottom of the longitudinal guide rail 825 and the second vertical connecting rod 827 connected to the driving member 83 is arranged at the bottom of the seventh slider 826, the driving member 82 can reciprocate inside the fixed frame 81 to drive away the rats. Since the driving device 8 is connected to the controller, the moving paths of the sixth slider 822 and the seventh slider 826 have been edited by the controller. Therefore, the moving paths of the sixth slider 822 and the seventh slider 826 are not described in detail in this embodiment.

[0095] Based on the above embodiments, the driving devices for the first slider 52, the second slider 53, the third slider 54, the fourth slider 72, the fifth slider 74, the sixth slider 822 and the seventh slider 826 are direct uses of existing technologies and can be one of screw drive, pulley drive and rack and pinion drive.

[0096] Based on the above embodiments, a lifting member is provided at the bottom end of the transfer frame 6. The lifting member is one of an electric push rod, a hydraulic rod, and a telescopic rod, so as to realize the vertical lifting movement of the transfer frame 6. An observation port 61 is provided on the side wall of the transfer frame 6. The observation port 61 is used to observe the position of the mouse in the transfer frame 6. And the transfer frame 6 is a hollow shell, that is, a through hole runs through the shell horizontally. When the transfer frame 6 rises to a certain position, the transfer frame 6 communicates with the outlet 11 of the first mouse cage 14 and the outlet 11 of the second mouse cage 15 respectively. And the inclination angle of the rear end opening of the transfer frame 6 is the same as the inclination angle of the opening 11 of the first mouse cage 14, and the inclination angle of the front end opening of the transfer frame 6 is equal to the inclination angle of the opening 11 of the second mouse cage 15, so as to realize the two ends of the transfer frame 6 closely fitting the outlet 11 of the first mouse cage 14 and the outlet 11 of the second mouse cage 15. The length of the transfer frame 6 is the distance between the front edge of the first limit groove 411 and the rear edge of the second limit groove 412. The opening sizes at both ends of the transfer frame 6 are not less than the size of the outlet 11 of the breeding mouse cage.

[0097] That is to say, through the setting of the transfer frame 6, a transfer channel for mice is formed. Since the length of the transfer frame 6 is too short, the situation where a mouse stays still in the transfer frame 6 will not occur, and the mouse is easily frightened. When the driving member 83 contacts the mouse, the mouse will quickly pass through the transfer frame 6 to realize the transfer from the first mouse cage 14 to the second mouse cage 15.

[0098] Based on the above embodiments, the thermal induction device 9 is directly used as the prior art, specifically an infrared sensor. The infrared sensor judges whether there is an animal in the defense area by detecting the infrared radiation of the animal from the environment, so as to accurately detect whether there is a mouse in the first mouse cage 14. That is to say, through the thermal induction device 9, it can be detected whether there is a mouse in the fixed frame 81.

[0099] Based on the above embodiments, the disinfection device of the present application includes an optical sensor and a spray head. The optical sensor can detect the light reflection of the first manipulator 44 and the second manipulator 45. When the first manipulator 44 and the second manipulator 45 move close to the optical sensor, the light reflection reaches a certain intensity and sends a signal to the controller, so as to control the spray head to spray alcohol, thereby completing the disinfection of the first manipulator 44, the second manipulator 45, and the driving device 8.

When the transfer frame 5 reaches the designated position, control the door opening device 7 to move the blocking door 123 to open the outlet 11 of the first cage 14 and the outlet 11 of the second cage 15, so that the first cage 14 and the second cage 15 are interconnected. After the first cage 14 and the second cage 15 are interconnected, control the driving member 83 to move towards the outlet 11 of the first cage 15, so as to drive the mice in the first cage 14 into the second cage 15. Control the thermal induction device 9 to detect whether there are mice in the first cage 14. When there are no mice in the first cage 14, control the door opening device to move the blocking door 123 to close the outlet 11 of the second cage 15. When there are mice in the first cage 14, control the driving member 83 to return to the starting point and move towards the outlet 11 of the first cage 14 again until the thermal induction device 9 does not detect mice in the first cage 14.

[0103] After the replacement is completed, control the fixing device 5, the driving device 8, and the door opening device 7 to return to their original positions, then control the first manipulator 44 to transfer the cage body of the first cage 14 located in the first limit slot 411 to the third loading vehicle 1113, and control the second manipulator 45 to transfer the second cage 15 located in the second limit slot 412 to the fourth loading vehicle 1114. Repeat the above operation steps until all the cages are replaced.
