[0027] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] The present application provides a feed storage device for an experimental mouse breeding system, referring to Figures 1 to 4 , including a feed hopper 1, a dividing structure 2 and a discharging cylinder 3 which are connected in sequence from top to bottom. After the feed is put into the feed hopper 1, the feed is discharged into the dividing structure 2 from the discharging end of the feed hopper 1. The dividing structure 2 can transport the feed to the discharging cylinder 3 in a quantitative and accurate manner, and discharge the feed to the feed transportation structure through the discharging cylinder 3. The feed is transported to the mouse cage of the experimental mouse through the feed transportation structure. The present application does not describe the feed transportation structure in detail.

[0030] Specifically, the diameter of the feed port of the feed hopper 1 is larger than the diameter of the discharge port of the feed hopper 1, and an inclined slope facing the discharge port is provided in the feed hopper 1, so that the feed poured into the feed hopper 1 can be discharged from the discharge port more smoothly.

[0031] The material distribution structure 2 includes a housing 21 and a material distribution wheel 22 disposed in the housing 21. The surface of the material distribution wheel 22 is surrounded by a plurality of spaced material distribution grooves 221. The extending direction of the material distribution grooves 221 is consistent with the thickness direction of the material distribution wheel 22. The depth of the material distribution grooves 221 enables the material distribution grooves 221 to accommodate feed particles. A driving motor for driving the material distribution wheel 22 to rotate is also fixed on the housing 21. After the feed is discharged from the discharge port of the feed hopper 1, it falls onto the material distribution wheel 22 and falls into the material distribution groove 221. The rotation of the material distribution wheel 22 drives the feed particles in the material distribution groove 221 to fall into the discharge barrel 3 for discharge.

[0032] Among them, the shell 21 includes a basic shell 211, a vertical plate 212 and an inclined plate 213. The basic shell 211 is fixedly connected to the side wall of the feed hopper 1. The vertical plate 212 is detachably arranged below the side wall of the discharge port of the feed hopper 1. The inclined plate 213 is detachably arranged between the vertical plate 212 and the discharge barrel 3, and the vertical plate 212 and the inclined plate 213 are both detachably connected to the basic shell 211.

[0033] The gap between the outer surface of the maximum diameter of the dividing wheel 22 and the vertical plate 212 and the inclined plate 213 is smaller than the particle size of the feed particles, and the discharge end of the feed hopper 1 is located above the horizontal area between the vertical plate 212 and the central axis of the dividing wheel 22, so that the feed discharged from the feed hopper 1 falls between the dividing wheel 22 and the vertical plate 212, but it is difficult for the feed particles to fall from the gap between the dividing wheel 22 and the vertical plate 212. The feed particles in the dividing trough 221 can only be transported to the inclined plate 213 through the rotation of the dividing wheel 22, and slide along the inclined plate 213 into the discharge barrel 3.

[0034] The feed distribution structure 2 of the present application can realize more quantitative discharge of feed, and the discharge amount of feed can be controlled by controlling the rotation speed of the feed distribution wheel 22.

[0035] Only one material distribution wheel 22 can be arranged in the housing 21, or multiple material distribution wheels 22 can be arranged. In the embodiment of the present application, two material distribution wheels 22 are arranged in the housing 21, and a discharge barrel 3 is arranged correspondingly below each material distribution wheel 22. Specifically, a partition plate 23 is arranged in the housing 21, and the housing 21 is divided into two chambers by the partition plate 23. The two material distribution wheels 22 are respectively placed in the two chambers, and each discharge barrel 3 is correspondingly connected to a chamber. The discharge barrel 3 is arranged to be tilted downward, so that the feed can be discharged into the feed transportation structure more smoothly along the discharge barrel 3.

[0036] The shell 21 also includes an inspection plate 6, which is detachably connected to the base shell 211. If a partition plate 23 is provided in the shell 21, the inspection plate 6 is also detachably connected to the partition plate 23. The inspection plate 6 is arranged in parallel with the vertical plate 212 and the inspection plate 6 serves as the side wall of all chambers. When a fault occurs inside the material distribution structure 2, the inspection plate 6 can be removed to realize the inspection and maintenance of each chamber.

[0037] A flexible guide plate 4 is fixed to the bottom wall of the discharge end of each discharge barrel 3. By providing the flexible guide plate 4, the feed in the discharge barrel 3 can be more accurately discharged into the feed transportation structure; specifically, the feed transportation structure includes a loading hopper 100, the loading hopper 100 moves to the bottom of the discharge barrel 3, and the flexible guide plate 4 extends into the loading hopper 100 and adheres to the inner wall of the loading hopper 100. At this time, the discharge barrel 3 discharges the feed, which can reduce the leakage of the feed from the loading hopper 100 and improve the transportation accuracy of the feed. After the discharge is completed, the loading hopper 100 can cross the flexible guide plate 4 and continue to transport upward.

[0038] Furthermore, a sensor 5 is fixed on the outer wall of each feed hopper 1 near the discharge end. The sensor 5 is used to sense whether there is feed in the plane where the sensor 5 is located in the feed hopper 1. When the sensor 5 senses that there is no feed in the corresponding plane in the feed hopper 1, it can remind the staff to add feed.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
