Description

Technical Field

[0001] The utility model relates to the technical field of breeding boxes, in particular to a closed multi-layer negative pressure insect breeding system. Background Art

[0002] Insect farming refers to the large-scale breeding of insects under artificial conditions through scientific management and technical means. This breeding method has received increasing attention in recent years, mainly because it has broad application prospects in the fields of food, feed, medicine and ecological protection.

[0003] Maggots are a type of insect. They are the larval stage of flies and usually live in organic matter such as carrion, garbage, and feces, feeding on and decomposing these substances. Maggots act as decomposers in the natural ecosystem and contribute to the circulation of organic matter.

[0004] Since fly maggots contain a lot of protein and can be used as raw materials for feed processing, some companies have begun to use feeding troughs in rooms to breed fly maggots. However, a certain amount of ammonia will be produced during the breeding process, which not only affects the normal work of workers, but also pollutes the environment.

By setting a limit baffle 15 and a straight baffle 16, the discharge trough 14 can be rotated to a vertical position by utilizing the rotational connection relationship between the discharge trough 14 and the inner wall of the discharge port 13. The discharge trough 14 can be fixed by utilizing the limit baffle 15 and the straight baffle 16, so that the discharge port 13 can be blocked by utilizing the discharge trough 14. The fly maggots are cultured in a closed manner in the breeding box 1, which can effectively prevent the leakage of harmful gases such as ammonia. At the same time, the negative pressure fan 5 can work to suck the harmful gases such as ammonia in the breeding box 1 into the exhaust pipe 4, and then the air purification filter 6 is used to purify and filter the gas, which not only effectively prevents the harmful gases such as ammonia from affecting the normal work of the workers, but also filters and purifies the harmful gases such as ammonia before discharging, effectively protecting the environment.

[0038] A control panel 29 is provided on the surface of the breeding box 1 , which is monitored by the temperature sensor 10 and the humidity sensor 11 . The temperature and humidity can be displayed in real time using the control panel 29 .

[0039] The length of the conveyor belt used by the breeding mechanism 9 in the utility model can be arbitrarily selected between 5m-20m, and the width can be arbitrarily selected between 0.5m-3m.

[0040] Working principle: When the closed multi-layer negative pressure insect breeding system is working, firstly, the straight baffle 16 needs to be rotated to a horizontal state, and then the discharge trough 14 needs to be rotated to a vertical state, and then the straight baffle 16 needs to be rotated to a vertical state. At this time, the front and rear surfaces of the discharge trough 14 are limited by the limit baffle 15 and the straight baffle 16, so that the discharge trough 14 can be fixed, and the discharge trough 14 blocks the discharge port 13. The fly maggots are bred in a closed manner in the breeding box 1, which can effectively prevent the leakage of harmful gases such as ammonia; food residues and water are respectively injected into the feed main pipe 2 and the liquid inlet main pipe 3 through a pump, and the fly maggot larvae can be mixed in the food residues. The food residues will fall from the discharge port of the feed branch pipe 19 onto the surface of the conveyor belt 17, and water will be sprayed on the food residues from the nozzle on the liquid inlet branch pipe 20. The servo motor can be controlled by the control panel 29 to drive the conveyor belt 17 to rotate, thereby Food residues and fly maggot larvae can be laid on the conveyor belt 17. By controlling the amount of water sprayed by the nozzle and the temperature of the constant temperature lamp 12, constant temperature and humidity can be achieved in the breeding box 1. At the same time, the negative pressure fan 5 can be used to suck harmful gases such as ammonia in the breeding box 1 into the exhaust pipe 4, and then the air purification filter 6 is used to purify and filter the gas. This not only effectively prevents harmful gases such as ammonia from affecting the normal work of workers, but also filters and purifies harmful gases such as ammonia before discharging, effectively protecting the environment. After the three-day breeding cycle is completed, the straight baffle 16 is rotated to a horizontal state. After the limit on the discharge chute 14 is released, the discharge chute 14 can be laid down, and then the servo motor can be started to pour food residues and the cultivated fly maggots into the discharge mechanism 8. The discharge mechanism 8 can be used to collectively export the cultivated fly maggots, thereby providing convenience for subsequent separation processing.
