Description

Technical Field

[0001] This utility model relates to the field of laboratory animal breeding cages, and more specifically, to an elevated breeding cage for laboratory animals. Background Technology

[0002] Elevated cages are special equipment used for raising animals in scientific experiments. The cages are usually designed as suspended structures and typically consist of a frame and a cage. The cages for raising animals are usually suspended or placed on the frame to avoid direct contact with the ground, which helps reduce pollution and improve ventilation. Existing elevated cages for raising laboratory animals require manual cleaning of animal feces regularly, which increases labor costs. To facilitate manual cleaning, elevated cages are often equipped with conveyor belts at the bottom of the cage to transport animal feces to the side of the cage for cleaning.

[0003] Existing elevated animal husbandry cages with conveyor belts attached to the bottom often result in animal feces sticking to the conveyor belt. To keep the cages clean, staff need to clean the conveyor belts regularly. Furthermore, when the flexible conveyor belt is used to transport animal feces, the feces at the edges of the conveyor belt can easily fall to the ground, requiring staff to clean the feces on the ground regularly. In view of this, we propose an elevated animal husbandry cage for experimental animals. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an elevated breeding cage for laboratory animals to solve the technical problem that the existing elevated breeding cages for laboratory animals require manual cleaning of animal feces regularly.

[0005] To solve the above technical problems, the present invention provides the following technical solution: an elevated feeding cage for experimental animals, comprising an elevated feeding cage, wherein a feces collection component and a support component are installed on the lower layer of the elevated feeding cage, and a drive component is connected to the power input end of the feces collection component.

[0006] The feces collection assembly includes an unwinding roller and a rewinding roller. One end of the unwinding roller is rotatably mounted on one end of the lower layer of the overhead feeding cage, and one end of the rewinding roller is rotatably mounted on the other end of the lower layer of the overhead feeding cage. A plastic film roll is non-rotatably sleeved on the unwinding roller, and a shaped sleeve is non-rotatably sleeved on the rewinding roller. One end of the plastic film roll passes through the top of the support assembly and is wound around the shaped sleeve. The shaped sleeve is provided with several annular protrusions and annular recesses at intervals.

[0007] The support component has an upward-opening arc shape in cross-section, with the openings at both ends facing the take-up roller and the unwind roller, respectively.

[0008] Preferably, the elevated rearing cage includes a frame, and a partition mesh is fixedly connected to the lower part of the frame, which divides the cage into a rearing chamber and a bottom chamber.

[0009] Preferably, both the unwinding roller and the winding roller have chamfered edges at their other ends, and both the unwinding roller and the winding roller have damping sheets attached to their outer surfaces.

[0010] Preferably, the supporting component includes an arc plate, the two ends of the top of the arc plate are on the same horizontal line and are fixedly connected to a suspension lug, a suspension rod is inserted into the suspension lug, and the suspension rod is fixedly installed on the top of the bottom chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The plastic film roll of this utility model is non-rotatingly sleeved around the unwinding roller installed at one end of the bottom chamber. The other end of the plastic film roll passes through the support assembly and is wound around the irregularly shaped sleeve outside the winding roller at the other end of the bottom chamber. The plastic film roll can automatically receive animal feces. When the feces need to be cleaned, it can be simply rolled up and packaged by the winding roller. The irregularly shaped sleeve is provided with several annular protrusions and annular depressions at intervals. When rolling up the plastic film and feces, the unevenly distributed feces can slide into the annular depressions, making the plastic film feces package more evenly distributed after rolling up. The entire cleaning process is reduced in manpower, freeing up manpower and reducing the probability of pathogen transmission. Moreover, the cleaning process does not disturb the animals with no or little human intervention, making the experimental results more reliable. It solves the problem that the existing elevated breeding cages for experimental animals require manual cleaning of animal feces regularly.

[0015] 2. This utility model also incorporates a non-rotating, irregularly shaped sleeve attached to the outside of the winding roller. The sleeve has several annular protrusions and annular recesses spaced apart. When winding the plastic film and feces, the unevenly distributed feces can slide into the annular recesses, making the feces package on the wound plastic film more evenly distributed. This reduces the occurrence of the plastic film being damaged due to excessive feces, and further solves the problem of the current overhead cages used for raising experimental animals requiring regular manual cleaning of animal feces.

[0026] like Figures 1 to 5 As shown, the present invention relates to an elevated breeding cage for experimental animals, comprising an elevated breeding cage 1, a feces collection component 2 and a support component 3 installed on the lower layer of the elevated breeding cage 1, and a drive component 4 connected to the power input end of the feces collection component 2.

[0027] The manure collection assembly 2 includes an unwinding roller 203 and a rewinding roller 201. One end of the unwinding roller 203 is rotatably installed at one end of the lower layer of the overhead feeding cage 1, and one end of the rewinding roller 201 is rotatably installed at the other end of the lower layer of the overhead feeding cage 1. A plastic film roll 204 is non-rotatably sleeved on the outside of the unwinding roller 203, and a non-rotatably sleeved on the outside of the rewinding roller 201 is a shaped sleeve 205. One end of the plastic film roll 204 passes through the top of the support assembly 3 and is wound around the outside of the shaped sleeve 205. The shaped sleeve 205 is provided with several annular protrusions and annular recesses at intervals.

[0028] The supporting component 3 has an upward-opening arc-shaped cross-section with its two ends facing the take-up roller 201 and the unwind roller 203, respectively. The plastic film roll 204 of this invention is non-rotatingly sleeved around the unwind roller 203 installed at one end of the bottom chamber 104. The other end of the plastic film roll 204 passes through the top of the supporting component 3 and is wound around the irregularly shaped sleeve 205 outside the take-up roller 201 at the other end of the bottom chamber 104. The plastic film roll 204 can automatically receive animal feces. When it is necessary to clean the feces, it is only necessary to roll it up and pack it by the take-up roller 201. The irregularly shaped sleeve 205 is provided with several annular protrusions and annular depressions at intervals. When rolling up the plastic film and feces, the unevenly distributed feces can slide into the annular depressions, making the plastic film feces pack more evenly distributed after rolling up. The entire cleaning process is less manpower-intensive, freeing up manpower and reducing the probability of pathogen transmission. Moreover, the animals are disturbed by no or few people during the cleaning process, making the experimental results more reliable.

[0029] Furthermore, the elevated feeding cage 1 includes a frame 101, with a partition mesh 103 fixedly connected to the lower part of the frame 101, which divides the cage into a feeding chamber 102 and a bottom chamber 104. The feeding chamber 102 is convenient for hanging or placing independent animal feeding cages. The partition mesh 103 can separate the feeding chamber 102 and the bottom chamber 104. At the same time, animal feces will pass through the partition mesh 103 and fall into the bottom chamber 104, making it convenient for the feces collection component 2 to collect the feces.

[0030] Furthermore, both the unwinding roller 203 and the take-up roller 201 have chamfered edges at their other ends, and damping sheets 202 are attached to the outside of both the unwinding roller 203 and the take-up roller 201 to facilitate the replacement of the plastic film roll 204.

[0031] Furthermore, the support component 3 includes an arc plate 301, with both ends of the top of the arc plate 301 on the same horizontal line and each fixedly connected to a suspension lug 302. A suspension rod 303 is inserted into the suspension lug 302, and the suspension rod 303 is fixedly installed on the top of the bottom chamber 104 to facilitate the installation of the support component 3.

[0032] Furthermore, the drive assembly 4 includes a first sprocket 401, which is fixedly installed at the end of the take-up roller 201. A chain 402 is externally engaged with the first sprocket 401, and a second sprocket 403 is internally engaged with the other end of the chain 402. The second sprocket 403 is fixedly installed at the end of the unwind roller 203, which facilitates the synchronous driving of the unwind roller 203 and the take-up roller 201 to rotate.

[0033] The power input end of the first sprocket 401 is connected to the power output end of the drive motor 404, which is mounted on the back of the overhead breeding cage 1.

[0034] Working Principle: This embodiment provides an elevated animal rearing cage for laboratory animals. In use, first, the individual animal rearing cage is suspended or placed inside the rearing chamber 102. Then, the door of the bottom chamber 104 is opened, and a new plastic film roll 204 is placed over the unwinding roller 203. Next, the outer end of the plastic film roll 204 is pulled, allowing the plastic film to pass over the supporting assembly 3. A non-rotating irregular sleeve 205 is then fitted over the take-up roller 201, and the end of the plastic film is wound around the irregular sleeve 205 outside the take-up roller 201 and fixed in place. When the animals defecate, the feces... The feces pass between the bottom of the animal cage and the partition mesh 103, landing on the plastic film. Since the plastic film passes through the support component 3, the arc-shaped section 301 of the support component 3 has an upward-opening arc shape, and both ends of the top of the arc-shaped section 301 are on the same horizontal line. When the top plastic film collects animal feces, the feces slide along the inner arc of the arc-shaped section 301 towards the lowest point in the center. The arc-shaped section 301 serves to support and concentrate the feces, focusing them in the middle of the plastic film and effectively reducing the chance of side leakage. When the feces need to be cleaned, external power is supplied. Electricity is supplied via an external switch to activate the drive motor 404, which in turn drives the first sprocket 401 to rotate. Since the first sprocket 401 is connected to a second sprocket 403 at the other end via a chain 402, the take-up roller 201 and the unwind roller 203 rotate synchronously. The take-up roller 201 and the shaped sleeve 205 roll up and wrap the plastic film containing animal feces at the top. The shaped sleeve 205 has several annular protrusions and annular recesses spaced apart on its outer surface, allowing unevenly distributed feces to slide into the annular recesses during the winding of the plastic film and feces. To ensure a more even distribution of the manure bags after winding, the unwinding roller 203 simultaneously unwinds new plastic film onto the support assembly 3. When the new plastic film is used up, the worker removes the packaged dirty plastic film from the outside of the winding roller 201, then loads a new plastic film onto the outside of the unwinding roller 203. Next, the worker pulls the outer end of the plastic film roll 204 so that the plastic film passes through the top of the support assembly 3 and is wound around the other end of the winding roller 201 and fixed in place. Once the new plastic film is laid out, it can be used again (the drive motor 404 is a commercially available product and is connected to an external control switch).
