DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1

[0032] like Figure 1 and 2 As shown, this embodiment discloses a multi-time adjustable cage wall fixed automatic feeding device, comprising a feeding box 1 and a feeding device 2. The feeding box 1 is used to store experimental mice; the feeding device 2 feeds food to the experimental mice in the feeding box 1.

[0033] The breeding box 1 comprises a box body 101, a cage cover 102 is arranged on the top of the box body 101, a feeding device 2 is arranged on the top of the breeding box 1, a avoidance opening is arranged on the cage cover 102 corresponding to the position of the feeding device 2, and the feeding device 2 is placed at the avoidance opening. A V-shaped groove 103 is arranged on the cage cover 102, and a water feeding device can be placed in the V-shaped groove 103.

[0034] The feeding device 2 includes a feed bin 201, which is used to store feed. The feed bin 201 is horizontally arranged at the avoidance opening of the cage cover 102. A fixing part 202 and a timing control part 203 are respectively provided at both ends of the feed bin 201. The fixing part 202 and the timing control part 203 are both engaged with the box body 101 of the feeding box 1. The feed bin 201 is rotatably connected to the fixing part 202, and the timing control part 203 drives the feed bin 201 to rotate circumferentially. A feeding window 204 is opened on the outer peripheral wall of the feed bin 201, and a blocking fence 205 is provided in the feeding window 204.

[0035] When the feeding device 2 is working, the timing control unit 203 drives the feed bin 201 to rotate circumferentially, so that the feeding window 204 on the outer peripheral wall rotates downward to face the feeding box 1. At this time, the feed in the feed bin 201 will not fall into the feeding box 1 due to the blocking of the blocking fence 205 (the feed is made into a block or a cylinder, and its size is larger than the gap of the blocking fence 205), but the head of the experimental mouse can reach into the feeding box 1 through the blocking fence 205 to gnaw the feed block. Among them, the timing control unit 203 can control the feeding time and interval.

[0036] The feed blocking fence 205 of the device adopts a precisely designed narrow-pitch wire structure, which can effectively prevent the feed blocks from falling prematurely and ensure a stable supply of feed. According to actual feeding experience, the feed blocks need to be gnawed to a very small volume (usually less than one gram) before they fall from the gaps in the fence. This weight is almost negligible relative to the daily feeding needs of experimental mice and will not have a significant impact on the experimental results or animal health. In addition, the breeder will regularly replace new feed to ensure that there is always an adequate supply of feed in the feed bin.

[0037] like Figure 3 and 4 As shown, in this embodiment, the fixing part 202 includes an end shell 202-1, and a slot 202-2 is provided on the outer wall of the end shell 202-1 to be inserted and matched with the feeding box 1. A bearing 202-3 is installed on the end shell 202-1, and the inner ring of the bearing 202-3 is plugged and matched with the cylindrical shaft 202-4, and the cylindrical shaft 202-4 is fixed to the end of the feed bin 201, and the end of the feed bin 201 fixed to the cylindrical shaft 202-4 is a closed end.

[0038] like Figure 5 and 6As shown, in this embodiment, the timing control unit 203 includes an end shell 203-1, and a second card slot 203-2 that cooperates with the feeding box 1 is provided on the outer wall of the end shell 203-1; a circuit board 203-3 and a rotating drive mechanism 203-4 are provided inside the end shell 203-1, and a screen 203-5 and a control button 203-6 are integrated on the circuit board 203-3. The circuit board 203-3 adopts a microcontroller, a built-in clock module, and supports multi-time period setting. The four control buttons 203-6 are connected to the IO port of the microcontroller. After the user sets the time, the microcontroller stores and executes the timing task. The microcontroller can control the rotating drive mechanism 203-4.

[0039] like Figure 6 As shown, in this embodiment, the rotating drive mechanism 203-4 includes a bracket 203-4-1, the bracket 203-4-1 is fixed inside the end shell 203-1, a steering gear 203-4-2 is arranged on the bracket 203-4-1, a steering wheel 203-4-3 is arranged on the driving part of the steering gear 203-4-2, the steering wheel 203-4-3 is connected to the rotating disk 203-4-4, and the rotating disk 203-4-4 is connected to the feed bin 201.

[0040] like Figure 7 and 8 As shown, in this embodiment, the feed bin 201 has an open structure at one end corresponding to the rotating disk 203-4-4, and the rotating disk 203-4-4 is snapped on the open end of the feed bin 201, which is convenient for the disassembly and installation of the rotating disk 203-4-4 and the feed bin 201, and convenient for the breeder to regularly replace new feed. At the same time, a protrusion 203-4-5 is provided on the outer peripheral wall of the rotating disk 203-4-4, and a groove is provided at the open end of the feed bin 201 to be embedded and matched with the protrusion 203-4-5. The rotating disk 203-4-4 drives the entire feed bin 201 to rotate circumferentially through the protrusion 203-4-5.

[0041] like Fig. 9 and 10 As shown, in this embodiment, a steering wheel clamping groove 203-4-6 is provided on the side of the rotating disk 203-4-4 facing the feed bin 201, and the steering wheel 203-4-3 is placed in the steering wheel clamping groove 203-4-6 by interference fit, and the middle part of the steering wheel 203-4-3 passes through the steering wheel clamping groove 203-4-5 and is fixed to the steering gear 203-4-2 by a bolt.

[0042] It should be noted that the circuit board 203-3 and the steering gear 203-4-2 need to be connected to a power module, which ensures that the motor and the control circuit are powered normally. The power module can be built into the end shell 203-1 or can be powered externally.

[0043] Embodiment 2

[0044] In this embodiment, Fig.11 As shown, a fastening bolt 202-5 is installed on the end shell 202-1. After the slot 202-2 is placed on the side wall of the feeding box 1, the fastening bolt 202-5 is tightened to make it rest against the side wall of the feeding box 1, so that the feeding device 2 can adapt to feeding boxes 1 of different thicknesses.

[0045] The rest of the structure in this embodiment is the same as that in the first embodiment.

[0046] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
