Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic laboratory animal breeding apparatus.

[0002]

2. Description of the Related Art The role played by experimental animals in basic research of biological systems including medicine has become more and more important in recent years. Various breeding devices have been conventionally used as breeding devices for maintaining and managing such experimental animals in a healthy manner.

Further, the most troublesome thing in animal breeding is the treatment of excrement, and most of the conventional breeding apparatuses treat excrement by hand by washing with water. In addition, after washing with water, the drainage system is clogged by hair removal, dust, and the like mixed in the excrement, and it is necessary to clean it frequently.

Further, since it is impossible to remove water immediately after washing with water, there is a problem that the humidity rises and the breeding environment is deteriorated. In addition, clean air must always be supplied to the breeding room, but the filter attached to the air outlet provided on the back wall of the breeding room does not become clogged due to hair removal or dust that is blown up by the blowing of air. There was also a problem that I had to wake it up and clean it frequently.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to completely automate the treatment of excrement and omit the conventional manual washing operation, and the water content is excrement. Automatically sucks and discharges hair from the breeding room together with hair removal, suppresses the increase in humidity in the breeding room, and prevents failure such as clogging of drainage system and exhaust system due to hair removal. The purpose is to provide breeding equipment.

[0006]

The gist of the present invention lies in the following configuration. Breeding apparatus main body provided with a required number of breeding rooms, an air supply fan installed on the top of the breeding apparatus main body, a sterilizing filter provided in the air intake section of the air supply fan, and the air supply fan An air supply main duct for sending air from the air supply branch pipe to the air supply main duct, and a branch from the air supply main duct is arranged above the front of each breeding room, and clean air that has been sterilized is ejected from the air discharge port. An air supply branch pipe, an exhaust fan installed on the top of the breeding apparatus body for sucking and discharging air in each breeding chamber, and an exhaust duct connecting the exhaust fan and the exhaust chamber,
In order to wash the breeding room, an exhaust and drainage pipe that connects the opening on the back side of the cleaning board of each breeding room to the exhaust chamber, and connects the side opposite to the side connecting to the exhaust chamber to the suction device The washing water supply pipe, which supplies the water that spouts periodically and spouts the washing water from the washing nozzle in the front part of the washing board in each breeding room, is arranged at the bottom of each breeding room and An automatic animal breeding device configured to lower as it goes deeper and comprising a washing board provided with an opening for sucking air and sewage on the inner wall surface, wherein the exhaust / drain pipe is connected to the vertical portion. A cleaning nozzle for ejecting cleaning water into the exhaust / drainage pipe is provided at the upper end, and a step is provided between the opening of the cleaning board and the air / sewage inlet of the exhaust / drainage pipe to further connect, and Each breeding in the breeding device body The door is a door with a small door in the center, the body of the breeding device is equipped with a washing hose for hand washing, and the drain hose is connected to the suction device and septic tank via a valve. Experimental animal automatic breeding device.

[0007]

Next, the operation of the present invention will be described. Clean air that has been sterilized is always supplied to the breeding room, but the air that has been sucked in by the air supply fan and sterilized by the sterilization filter is fed through the air supply main duct and air supply branch pipe. It is released indoors. The air is blown out from the air discharge port provided in the air supply technique tube arranged above the front part of the breeding room.

Further, the air discharged into the breeding room is sucked into the exhaust / drain pipe through the opening on the back side of the washing plate provided at the bottom of the breeding room, and finally discharged outside by the exhaust fan. Is.

On the other hand, the cleaning of the breeding room is performed as follows. The inside of the breeding room is washed about once an hour. Water is ejected from the washing nozzle located in the front of the washing board at the bottom of the breeding room, while at the same time, the suction / drainage pipe is strongly sucked by a suction device, and the inside of the breeding room is kept under negative pressure to remove hair and feces. It strongly sucks out the wash water containing water and finally flows the wash water from the drain hose to the septic tank.

When cleaning is performed, the air remaining in the breeding room is also sucked together with the cleaning water. Also, at this time, water is ejected from the exhaust pipe cleaning nozzle into the exhaust / drain pipe to clean the inside of the exhaust / drain pipe, so that the inside of the exhaust / drain pipe through which air and cleaning water pass is clogged with hair removal or feces. It does not cause a failure.

Further, since a step is provided between the opening of the washing board and the air / sewage inlet of the exhaust / drainage pipe, the air and the sewage can be completely separated.

Further, the door of each breeding room is a door provided with a small door in the center, and the breeding apparatus main body is equipped with a washing hose for hand washing, so that it can be washed manually when necessary. If possible and at that time, the small door of the breeding room is opened and water is sprayed with the washing hose for hand washing, but the splashed water hits the inner wall of the large door and is prevented from scattering outside.
