Description

Technical Field

[0001] The present application relates to the technical field of animal housing, and in particular to an SPF-level experimental animal breeding device with automatic feces flushing. Background Art

[0002] SPF-level experimental animals refer to animals that are clean animals and do not carry specific pathogens and parasites that may interfere with the experiment. Strict control of microorganisms and parasites is required. As internationally recognized standard experimental animals, SPF-level experimental animals can be used in many fields, such as biomedical research, vaccine manufacturing, biological identification, human tumor xenotransplantation, preclinical pharmacology and toxicology research of new drugs, carcinogenicity testing, etc.

[0003] An existing feeding device is to lay a fabric pad at the bottom of the feeding box to absorb urine and feces, and then replace the fabric pad regularly. However, the fabric pad needs to be sterilized before use. If there are a large number of feeding devices, the workload of manual replacement is large, and there is a situation where replacement is not timely. Moreover, replacement of the fabric pad is likely to cause urine and feces to be dispersed in the feeding device, increasing the risk of disease transmission. In addition, because the feet and abdomen of the animal are in contact with urine and feces for a long time, it is easy to cause animal dermatitis, which greatly affects the quality of the animal.

[0004] Another existing breeding device is a box with a mesh bottom, under which a feces collection tray is placed for manual collection at regular intervals. However, manual feces collection makes microorganisms more likely to disperse and increases the risk of disease transmission. If feces are not cleaned up in time while accumulating in the feces collection tray under the cage, microorganisms in the environment are easily dispersed with ventilation, further increasing the pollution problem.

[0005] Therefore, it is necessary to provide an SPF-level experimental animal breeding device with automatic feces flushing. Utility Model Content

[0006] In order to timely and effectively process animal feces in batches and reduce the spread of diseases caused by the dispersion of microorganisms, the present application provides an SPF-level experimental animal breeding device with automatic feces flushing, which is implemented using the following technical solution.

[0028] The present application is further described in detail below in conjunction with all the accompanying drawings. Example 1

[0029] The present embodiment discloses an SPF-level experimental animal breeding device with automatic feces flushing, which is used for breeding animals such as rabbits or guinea pigs.

[0030] Reference Figure 1 The breeding device mainly includes a frame 1 and a cage 7. The frame 1 is a frame-type structure. The frame 1 is provided with height positioning strips 11 in pairs along the length direction of the frame 1. The lower wall of the height positioning strips 11 is fixed with a pair of hanging frames 2 arranged along the width direction of the frame 1. The cross section of the hanging frame 2 is a square frame shape with one end open, that is, a "]" shape. The hanging frame 2 has two opposite walls, one of which is fixedly connected to the lower wall of the height positioning strip 11, and the opening directions of the two adjacent hanging frames 2 are opposite.

[0031] Reference Figure 2 The cage 7 is a rectangular parallelepiped structure in a mesh shape. The upper wall has two sides provided with clips 76 extending out of the cage 7 along the length direction. The width of the clips 76 enables the cage 7 to be inserted into two opposite hanging frames 2. The clips 76 are lower than the height of the hanging frames 2. The end of the inner wall of the hanging frames 2 in contact with the clips 76 is provided with a hemispherical protrusion 21. When the cage 7 needs to be inserted into the rack 1 or taken out of the rack 1, the cage 7 needs to be lifted up above the hemispherical protrusion 21 and then moved toward the clips 76, thereby ensuring that the cage 7 is stable on the clips 76 and is not easy to slide off.

[0032] The cage 7 includes a body 75 and a cage door 74. The cage door 74 is hinged on one side wall of the cage 7, and the hinge axis is parallel to the side wall. A sheet-shaped door catch 72 is hinged on the side wall opposite to the hinge axis, and the hinge axis is a catch axis 73. The direction of the catch axis 73 is perpendicular to the side wall, and the sheet-shaped door catch 72 is parallel to the side wall. When the cage 7 needs to be opened, the door catch 72 is rotated around the catch axis 73 so that the thin flat iron wire extending from the cage door 74 is no longer restricted between the door catch 72 and the side wall; when the cage 7 needs to be installed, the door catch 72 is rotated from the position of the milled flat steel wire to open the cage 7.

[0033] A feeding box 71 is provided on the cage door 74 , and both ends of the feeding box 71 are opened. The feeding box 71 is inserted into the cage door 74 , one opening goes deep into the feeding box 71 , and the other opening is outside the cage door 74 .

[0034] Reference Figure 1 The height of the cage 7 is less than the distance between the two adjacent upper and lower height positioning bars 11, and the entire cage 7 is suspended on the frame 1, and the bottom of the cage 7 does not contact the height positioning bar 11. When the animal in the cage 7 discharges urine or feces, since the bottom of the cage 7 is meshed, the urine or feces will fall directly downwards and will not remain or accumulate in the cage 7.

[0035] A dirt guide inclined plate 52 is fixed between two relative height positioning strips 11 of the same height. Two dirt guide inclined plates 52 are provided on each layer. The side away from each other is higher, and the side where the two dirt guide inclined plates 52 are close to each other is lower. The two dirt guide inclined plates 52 do not touch each other, and there is a certain distance between them. The edges of the two dirt guide inclined plates 52 and the side walls of the two height positioning strips 11 form a collection port 54 that can go to the next layer. A hollow dirt guide empty frame 51 is formed by extending downward along the collection port 54. The lower end of the dirt guide empty frame 51 does not touch the dirt guide inclined plate 52. The dirt guide empty frame 51 of the lowest layer is relatively small in height and is connected to the sewage pipe 53 as a whole to discharge the dirt collected in the upper layers uniformly.

[0036] The frame 1 is provided with a water inlet pipe 3, which is divided into a first water branch pipe 31 and a second water branch pipe 32 on the bottom wall of the first cage 7. The first water branch pipe 31 is arranged on the side of the frame 1 close to the higher position of the sewage guide inclined plate 52 on one side, and the first water branch pipe 31 extends vertically; the second water branch pipe 32 is arranged on the side of the frame 1 close to the higher position of the sewage guide inclined plate 52 on the other side. A water spray box 41 is abutted against the upper wall of the end of the higher end of each sewage guide inclined plate 52. The length of the water spray box 41 is the same as the width of the sewage guide inclined plate 52. A water spray nozzle 42 pointing to the lower end of the sewage guide inclined plate 52 is arranged along the length direction of the water spray box 41. The water spray box 41 is connected to the first water branch pipe 31 or the second water branch pipe 32 through the flushing branch pipe 4.

[0037] When the animal urine or feces in the cage 7 is discharged from the bottom of the cage 7, it will fall onto the sewage guide inclined plate 52, and the urine or animal feces that are easy to roll will roll down to the collection port 54 and then pass through the sewage guide empty frame 51 to finally reach the sewage pipe 53 for unified discharge and treatment. If it is sewage that is not easy to shift due to the tilt, pressurized water is introduced into the water inlet pipe 3, and the water is sprayed through the flushing branch pipe 4, the water spray box 41 and the water spray nozzle 42, thereby flushing the sewage guide inclined plate 52, and flushing the sewage that is not easy to roll down naturally to the collection port 54 for discharge.

[0038] The frame 1 has four vertical support rods, and each support rod is connected with a leveling bolt 6 for adjusting the overall level of the breeding device.

[0039] The working principle of this embodiment is as follows: animal urine and feces are discharged from the mesh cage 7, the dirt guide inclined plate 52 tilts the easily displaced dirt to the collection port 54, and the water sprayed from the water nozzle 42 flushes the dirt that is not easily displaced on the dirt guide inclined plate 52 to the collection port 54 for discharge. Example 2

[0040] The difference between this embodiment and the first embodiment is that the frame 1 is wider and deeper, another cage 7 is arranged behind the cage 7, two first water distribution pipes 31 are arranged on one side of the frame 1, and two second water distribution pipes 32 are arranged on the other side of the frame 1. The number of corresponding water spray boxes 41 is also twice as much as before. Finally, the waste is still collected in a sewage pipe 53 for unified treatment.

[0041] The implementation principle of this embodiment is: the cages 7 can be placed more centrally, more water spray boxes 41 can be arranged, and the volume of a single water spray box 41 is smaller, which is convenient for maintenance and replacement. Example 3

[0042] The difference between this embodiment and embodiment 1 is that only one cage 7, one sewage guide inclined plate 52 and one water spray box 41 are provided on the frame 1, the water spray box 41 is externally connected to a water pipe, and the lower end of the sewage guide inclined plate 52 corresponds to the entrance position of the manure ditch.

[0043] The implementation principle of this embodiment is: the equipment is simple, the treatment of animal urine and feces is convenient and easy to operate, and it is placed at the entrance of the feces ditch to save space. Example 4

[0044] The difference between this embodiment and embodiment 1 is that the two sewage guiding inclined plates 52 on the same layer are inclined along the width direction, that is, the sewage guiding inclined plate 52 corresponding to the front of the cage 7 is located higher, and the sewage guiding inclined plate 52 corresponding to the rear of the cage 7 is located lower, the two sewage guiding inclined plates 52 are connected in the length direction without a gap, and a gap is provided between the sewage guiding inclined plate 52 at the position corresponding to the rear of the cage 7 and the frame 1, and a sewage guiding empty frame 51 is provided below the gap, that is, the sewage guiding empty frame 51 is arranged at the rear of the cage 7 along the length direction of the frame 1.

[0045] The implementation principle of this embodiment is: the frame 1 can allocate more space to the cage 7 along the length direction, and for the space of a specific size on the site, a better space matching can be obtained, and the location distribution of animal urine and feces can be more easily and uniformly processed. Example 5

[0046] The difference between this embodiment and the first embodiment is that the lower wall of the height positioning bar 11 is no longer fixed with a hanging frame 2, but is fixed with a mesh plate 8, which includes transverse and longitudinal stainless steel bars. The cage 7 is not provided with a clamping bar 76. When the cage 7 needs to be placed, the cage 7 is hung under the mesh plate 8 with a plurality of "S"-shaped hooks (not shown in the figure). One end of each "S"-shaped hook pulls the cage 7, and the other end is hung on the grid of the mesh plate 8.

[0047] The implementation principle of this embodiment is: one rack 1 can be suitable for cages 7 of various sizes, so that the cages 7 can be conveniently hung at any position of the rack 1 .

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
