Description

Technical Field

[0001] The utility model relates to the technical field of laboratory animal breeding devices, in particular to an overhead breeding cage for laboratory animal breeding. Background Art

[0002] In zoology and biomedical experiments, small animals such as monkeys and dogs are often used as experimental subjects. These experimental subjects often need to be kept in cages for observation and operation. In order to facilitate observation, the animals need to be raised individually. Currently, most cages for raising animals have cage walls set as fences, and cage doors and locks are used to place the animals in the cages.

[0003] Animals living in cages will produce waste such as feces and breed a large number of bacteria. Traditional cages are not easy to clean, which has a great impact on the growth of animals. In addition, when feeding the animals, people need to enter the cages to feed them, which can easily cause the animals to stress and attack the people, causing danger. Therefore, an overhead feeding cage for experimental animal breeding is proposed.

[0004] A large animal experiment breeding cage disclosed in the announcement number CN217905686U, although, the technical solution of the large animal experiment breeding cage is as follows: it includes a cage body, the top surface of the cage body is fixedly connected with a mounting plate, and the interior of the cage body is provided with a food box; a storage block, the storage block is arranged on the bottom surface of the cage body, and the top surface of the storage block is provided with a storage groove; a flushing component, the flushing component is arranged on one side of the storage block, and is used to flush the interior of the storage groove. When the heating plate is working, the heating plate can quickly dry the residual moisture on the top surface of the placement plate. When the staff places the large animal in the interior of the cage body, a sealing plate is arranged. When the staff takes the sealing plate out from the inside of the water inlet hole, the staff can use a spray gun to clean the excrement on the top surface of the placement plate. At the same time, the excrement during flushing can flow out through the sewage pipe, so as to facilitate the storage and transportation of the excrement in the later stage.

[0005] Although the above patent sets a sealing plate, after the staff takes the sealing plate out from the inside of the water inlet, the staff can use a spray gun to clean the excrement on the top surface of the plate. At the same time, the excrement during flushing can flow out through the sewage pipe, so as to facilitate the storage and transportation of the excrement at a later time; however, the device lacks an automatic feeding function and requires the staff to feed manually, which takes up the staff's time and increases management costs and labor costs.

[0006] Therefore, it is necessary to invent a kind of experimental animal breeding and use an overhead breeding cage to solve the above problems. Utility Model Content
