[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4 Provided is a feeding device for laboratory mice. The present invention includes a support frame 1, a feeding box 2 fixedly connected to the top of the support frame 1, a storage box 3 fixedly connected to the top of the feeding box 2, a guide pipe 4 fixedly connected to the bottom of the storage box 3 and extending into the interior of the feeding box 2, an electric valve 5 installed inside the guide pipe 4, a motor 6 fixedly connected to the outside of the feeding box 2, a rotating shaft 7 fixedly connected to the outside of the output shaft of the motor 6 and rotatably connected to the interior of the feeding box 2, a fixing plate 8 fixedly connected to the outside of the rotating shaft 7, a connecting shaft 9 rotatably connected to the interior of the fixing plate 8, a rotating device 10 fixedly connected to the connecting shaft 9 on the outside of the fixing plate 8, a holding frame 11 fixedly connected to the outside of the connecting shaft 9, two collection frames 12 installed inside the feeding box 2, a discharge pipe 13 fixedly connected to the outside of each of the two collection frames 12, and a limit plate 14 fixedly connected to the interior of the feeding box 2.

[0028] Both collection boxes 12 are wider at the top and narrower at the bottom. Both discharge pipes 13 are equipped with switch valves. The front discharge pipe 13 is longer and its discharge port is flat.

[0029] In this embodiment, during actual use, the opening of the collection frame 12 is larger than the opening of the container frame 11, which can collect and process feed that falls or spills from the container frame 11. The valve can be manually opened and closed so that the rear discharge pipe 13 can be closed during use and opened again for collection when unified processing is required. The flat discharge nozzle of the front discharge pipe 13 facilitates the spreading of feed so that the feed can be spread evenly in the rectangular feed trough when feeding, making it convenient for multiple mice to eat at the same time. In addition, the small opening of the flat discharge pipe 13 will not allow the mice to escape.

[0030] The limiting plate 14 is located directly above the rear collection frame 12, and the bottom surface of the limiting plate 14 is flush with the top surface of the container frame 11.

[0031] In this embodiment, during actual use, the loading frame 11 will pass by the limiting plate 14 above the rear collection frame 12 during its movement. The limiting plate 14 can scrape and flatten the feed piled up in the loading frame 11 and make the feed fall into the rear collection frame 12.

[0032] The rotating device 10 includes an electric push rod 101 fixedly connected to the outside of the fixed plate 8, a rack 102 fixedly connected to the outside of the electric push rod 101 and slidably connected to the inside of the fixed plate 8, and a gear 103 meshing with the rack 102 fixedly connected to the outside of the connecting shaft 9.

[0033] In this embodiment, during actual use, the electric push rod 101 can drive the rack 102 to move, and under the mutual meshing of the gear 103 and the rack 102, the connecting shaft 9 and the outer container frame 11 can rotate. At the same time, the rotation angle is adjusted by the number of meshing teeth of the gear 103 and the rack 102, so that the rotation angle of the container frame 11 is 180 degrees. The back and forth flipping of the container frame 11 can collect and put the feed in.

[0034] The fixed plate 8 has a groove inside, and the rack 102 has a slider 15 that is slidably connected to the groove on the outside.

[0035] In this embodiment, during actual use, the rack 102 will drive the slider 15 on its outer side to move during the movement. The slider 15 is in contact with the slide groove, and the direction of the slide groove is parallel to the pushing direction of the electric push rod 101, so as to further restrict the movement direction of the rack 102 and enhance its movement stability.

[0036] The centers of the symmetry axes of the two collection frames 12 are equidistant from the centers of the rotation axes 7.

[0037] In this embodiment, during actual use, as the holding frame 11 rotates through the rotating shaft 7, the holding frame 11 will pass through the center of the two collection frames 12 respectively. When the holding frame 11 located at the center pours out the feed inside, it is not easy for the feed to leak out.

[0038] Working principle:

[0039] When feeding the mice in their troughs, the front discharge pipe 13 of the device can be extended into the trough. The discharge pipe 13 can be made of a deformable hard material. Simultaneously, the front valve is opened. The storage bin 3 stores the feed. The electric valve 5, in conjunction with a time relay, controls its opening and closing by setting a timer on the timer. Opening and closing the electric valve 5 releases feed from the storage bin 3 into the lower container 11. A large amount of feed is added, piling up in the container 11. The container 11 can be installed and removed from the connecting shaft 9, allowing for easy changes to its size. Then, the motor 6 is started, causing the container 11 to move around the rotating shaft 7 and pass through the limit plate 14 to extend... Excess feed on the outside of the holding frame 11 is scraped off and falls into the rear collection frame 12. Finally, it rotates to the top of the front collection frame 12, and the holding frame 11 is flipped by the rotation of the connecting shaft 9 caused by the electric push rod 101, so that a certain amount of feed is put into the feeding trough of the mouse through the front discharge pipe 13. The motor 6 and the electric push rod 101 are used in conjunction with an encoder and a motor controller. Using a professional motion controller, a control program is written to centrally control the motor 6 or the electric push rod 101, monitor the rotation angle and speed of the motor in real time, and convert this information into electrical signals to feed back to the controller, so as to achieve precise control of the motor and the electric push rod. The rear discharge pipe 13 is normally closed, which can store the feed in the rear collection frame 12. Afterwards, the feed needs to be discharged through the valve at regular intervals for reuse.
