Description

Technical Field

[0001] The invention relates to the technical field of black soldier fly breeding, and in particular to a black soldier fly breeding system. Background Art

[0002] The black soldier fly is a saprophytic insect of the family Solenopsis that can feed on livestock and poultry manure and domestic garbage to produce high-value animal protein feed. It can be utilized as a resource because of its rapid reproduction, large biomass, wide diet, high absorption and conversion rate, easy management, low feeding cost, and good palatability for animals. Its larvae are called "phoenix insects" and have become a resource insect as famous as maggots, mealworms, and barley worms, and have been promoted worldwide.

[0003] Black soldier flies are native to America and have been introduced to my country in recent years. They are now widely distributed in Guizhou, Guangxi, Guangdong, Shanghai, Jiangsu, Zhejiang, etc. In practical applications, black soldier flies are widely used to treat livestock and poultry manure (such as chicken manure, pig manure and fresh chicken manure), kitchen waste and other perishable waste.

[0004] In the existing black soldier fly breeding process, it is necessary to first hatch the eggs and obtain small larvae. After the small larvae are cultured to 4-5 mm in a larval breeding workshop, the larvae are inoculated on the feed and placed in a breeding box, and the breeding box is transferred to the next breeding workshop for breeding. During this process, the black soldier flies continue to grow in the breeding box. When the black soldier flies grow to a body length of or more than 2 cm, commercial worms are obtained. Then, the breeding box needs to be transferred to an insect excrement separation workshop to separate the commercial worms from the insect excrement and residual feed. The separated commercial worms can be sold as commodities, and the remaining insect excrement can also be used as organic fertilizer.

[0072] Step 1), the bottom plate 43 is driven to move to the material receiving position by the first motor 50, and the box body 45 on the bottom plate 43 is located below one end of the unloading conveyor belt 8, and the insect excrement mixture 63 on the unloading conveyor belt 8 falls into the box body 45 through the movement of the unloading conveyor belt 8; after the box body 45 completes the material receiving, the bottom plate 43 is driven to move to the separation working position by the first motor 50.

[0073] Step 2), drive the rotating shaft 59 to rotate to the working angle position through the second motor 60, at which time the spreading rod 49 on the rotating shaft 59 is perpendicular to the bottom surface of the box body 45; the servo moving device 54 drives the moving frame 48 to move along the length direction of the box body 45, and spreads the insect feces mixture 63 in the box body 45 through the spreading rod 49; then drive the rotating shaft 59 to rotate to the retracted angle position through the second motor 60, and after the rotating shaft 59 reaches the retracted angle position, the spreading rod 49 on the rotating shaft 59 is parallel to the bottom surface of the box body 45.

[0074] Step 3), pull out the mesh film 61 on the mesh film roll 51 and make the mesh film 61 cover the insect excrement mixture 63 in the box body 45; after the mesh film 61 covers the insect excrement mixture 63, the air between the mesh film 61 and the upper surface of the insect excrement mixture 63 is extracted through the exhaust pipe 65, so that a low air pressure is formed between the mesh film 61 and the insect excrement mixture 63, so that the mesh film 61 and the upper surface of the insect excrement mixture 63 are fitted together; pull out the sealing film 62 on the sealing film roll 52, cover the sealing film 62 on the mesh film 61, and leave a gap layer 64 between the mesh film 61 and the sealing film 62.

[0075] Step 4), the heating device is turned on, and the heating temperature of the heating device is higher than the suitable living temperature of the black soldier flies; the air inlet duct 67 and the exhaust duct 66 are respectively connected to the two ends of the sealing film 62, the air inlet duct 67 and the exhaust duct 66 are respectively connected to the hole layer between the mesh film 61 and the sealing film 62, and the air duct is connected to the blower; cooling air is blown into the hollow layer 64 by the blower, and the exhaust duct 66 is used to discharge the excess air in the hollow layer 64; the heating of the heating device prompts the black soldier flies to crawl into the hollow layer 64 between the mesh film 61 and the sealing film 62 through the holes on the mesh film 61.

[0076] The specific heating temperature of the heating device is 40°C-47°C. The temperature of the cooling air blown into the air gap layer 64 by the blower is 20°C-25°C, and the cooling air can be ambient air that meets this temperature range; by blowing cooling air into the air gap layer 64, the air temperature in the air gap layer 64 can be kept between 20°C-25°C, which is a temperature range suitable for the life of black soldier flies, and the insect excrement mixture 63, due to the heating effect of the heating device, will gradually become higher than the suitable temperature range for black soldier flies, forming a stuffy and unsuitable environment for the life of black soldier flies under the mesh film 61, so that a significant difference in ambient temperature is formed between the air gap layer 64 and the insect excrement mixture 63, and the oxygen under the mesh film 61 will be continuously consumed by black soldier flies and form an oxygen-deficient environment, while the air gap layer 64 is rich in oxygen, and the above factors will effectively prompt the black soldier flies to drill out of the insect excrement mixture 63 and transfer to the air gap layer 64.

[0077] Step 5), the sealing film 62 and the mesh film 61 are removed from the box body 45. When removed, the black soldier flies in the hollow layer 64 are removed together, and feces and residual feed are left in the box body 45, thereby achieving insect-feces separation.

[0078] The present invention has the following advantages:

[0079] 1. The present invention realizes a high degree of mechanized operation in the black soldier fly breeding process, saves a large number of manual handling operations of the breeding boxes, greatly reduces the labor cost in the breeding process, thereby reducing the breeding cost and improving the breeding efficiency.

[0080] 2. The present invention realizes the separation of commercial insects through an insect excrement separation device. During the insect excrement separation process, the change of environmental temperature is used to induce black soldier flies to crawl into the hole layer between the mesh membrane and the sealing membrane, thereby realizing the autonomous separation of black soldier flies and insect excrement. During the separation process, no forced external force is applied to the black soldier flies to promote their separation, and no mechanical vibration is generated, thereby reducing the damage to the living black soldier flies, thereby reducing the mortality rate of black soldier flies during the insect excrement separation process, and improving the economic benefits of black soldier fly breeding.

[0081] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
