The top of the base 1 is provided with a mounting platform 2, and both sides of the mounting platform 2 are higher than the middle position. The top of the mounting platform 2 is provided with a mounting plate 3 by bolt connection, and a cage body 4 is embedded in the middle of the mounting plate 3. A fixed shaft 5 is vertically provided at the center of the cage body 4, and an external thread is opened on the upper part of the fixed shaft 5. A cover is slidably provided on the fixed shaft 5. The cage body 4 is provided with a cover 6, and the cover 6 cooperates with the cage body 4. A cleaning component 7 capable of cleaning excrement is arranged in the recess of the mounting platform 2. A slide rail 8 is symmetrically embedded on the front side of the top of the mounting plate 3. A feeding frame 9 is slidably arranged in the slide rail 8. A square hole is opened on the front side of the cage body 4. The side wall of the feeding frame 9 is consistent with the square hole. The feeding frame 9 cooperates with the square hole. An internal thread is opened at the center position of the handwheel 10. The handwheel 10 is screwed together with the fixed shaft 5 through a thread. A grabber 11 for grabbing animals is sleeved on the fixed shaft 5.

[0020] like Figure 1 As shown, the cleaning assembly 7 includes a conveying roller 71, a conveyor belt 72 and a motor 73. The conveying rollers 71 are symmetrically rotatably arranged at the recessed part of the mounting platform 2, and the conveyor belt 72 is arranged between the two conveying rollers 71. The motor 73 is arranged on the right side of the front side wall of the mounting platform 2 by bolt connection. The output shaft of the motor 73 is connected to the front end of the adjacent conveying roller 71 through a coupling, and a blanking hole 74 is vertically opened on the right side of the mounting platform 2.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, the grabber 11 includes a sleeve 111, a fan-shaped frame 112, a rotating seat 113, an arc baffle 114, an arc slider 116, a connecting rod 117 and a handle 118. The sleeve 111 is inserted into the fixed shaft 5. The inner hole diameter of the sleeve 111 is larger than the diameter of the fixed shaft 5. The sleeve 111 is provided with a fan-shaped frame 112. The bottom of the sleeve 111 is rotatably provided with a rotating seat 113. The rotating seat 113 is provided with an arc baffle 114.

The top of the arc slider 116 is provided with a handle 118.

[0022] Animal excrement falls onto the conveyor belt 72 through the gap between the cross bars at the bottom of the cage 4. When excrement treatment is required, the staff controls the motor 73 to work, and the motor 73 drives the conveyor roller 71 to rotate, so that the conveyor belt 72 moves to the right, and the excrement on the conveyor belt 72 moves to the right and then falls into the drop hole 74, and then falls into the collection frame placed in the drop hole 74, thereby playing the role of excrement cleaning. When feeding is required, the staff pours the food into the feeding frame 9, and then pushes the feeding frame 9 backwards, and the feeding frame 9 enters the cage 4. When it is necessary to capture an animal for experimental research, the staff first rotates and removes the handwheel 10, takes out the grabber 11 and the cover 6, and uses the sleeve 111 of the grabber 11 to cover the fixed shaft 5 and move downward, while moving downward, rotating and adjusting the position of the fan-shaped frame 112, and the fan-shaped frame 112 is gradually located above the animal that needs to be captured for the experiment, and then the animal is encircled by the fan-shaped frame 112, and then the staff pulls the arc-shaped slider 116 along the arc-shaped groove 115 through the handle 118, and the arc-shaped slider 116 pulls the arc-shaped baffle 114 to rotate through the connecting rod 117, thereby sealing the bottom of the fan-shaped frame 112, and pulling the fan-shaped frame 112 upward to move the animal out without touching the animal. The device has a simple structure and can be cleaned quickly. It is also convenient for contactless capture of animals and is suitable for laboratory breeding of small animals.

[0023] Embodiment 2: Based on embodiment 1, Figure 3 As shown, it also includes a fixed block 12, a fixed rod 13 and an arc-shaped grabbing rod 14. The two side walls of the fan-shaped frame 112 are provided with fixed blocks 12, the tops of the fixed blocks 12 are provided with fixed rods 13, and an arc-shaped grabbing rod 14 is provided between the two fixed rods 13. The staff can better drive the grabber 11 to grab small animals through the arc-shaped grabbing rod 14.

[0024] like Figure 2As shown, a scraper 15 is also included. The scraper 15 is obliquely arranged on the mounting platform 2 above the drop hole 74. The scraper 15 is arranged in close contact with the conveyor belt 72. The scraper 15 can further scrape off the excrement on the conveyor belt 72, making it convenient to clean the conveyor belt 72.

[0025] like Figure 1 As shown, it also includes bristles 16, which are arranged at intervals on the conveyor belt 72. The bristles 16 are made of soft plastic. When the conveyor belt 72 rotates in a cycle, the bristles 16 are driven to rotate upward, and the bristles 16 can brush off the excrement adhered to the cross bar at the bottom of the cage body 4.
