Description
Technical Field
[0001] The present invention relates to the technical field of kitchen waste treatment equipment, and in particular to an automatic black soldier fly breeding device. Background Art
[0002] Black soldier fly farming technology is gaining increasing application in the treatment of food waste. Using biomass organic waste to cultivate black soldier flies not only allows for the efficient and harmless treatment of large quantities of food waste, preventing the proliferation of pathogenic microorganisms and environmental pollution caused by improper food waste disposal, but also allows for the harvest of significant numbers of black soldier fly larvae. These larvae are rich in protein and fat, making them an important, high-nutrition feed, widely used in the production of high-quality poultry and livestock products such as free-range chickens.
[0003] However, while existing black soldier fly farming technology has matured and some black soldier fly farming equipment has been gradually adopted, problems such as low farming efficiency, low automation, and high labor consumption still exist. These issues have led to high costs and relatively low yields in the black soldier fly farming process, restricting the widespread use of black soldier flies as an important protein feed. This has also indirectly increased the price of high-quality poultry and livestock products fed with black soldier flies, hindering their wider market promotion.
[0004] In recent years, intelligent equipment has been increasingly used in various aquaculture applications. However, the lack of effective intelligent calcium-based aquaculture equipment for black soldier flies has not effectively alleviated the current challenges of aquaculture. The key to addressing the shortcomings of existing black soldier fly aquaculture and achieving efficient aquaculture lies in developing an automated, continuous aquaculture method and corresponding equipment to address the current issues of low automation, low equipment utilization, and inability to achieve continuous aquaculture in tray aquaculture. Summary of the Invention
[0005] In view of the problems existing in the breeding of black soldier flies described in the background art, the present invention provides an automated black soldier fly breeding device. The device realizes the automatic breeding of black soldier flies in the following manner.
[0006] An intelligent black soldier fly breeding system comprises a breeding module, a feeding system, a screening system and a control system.
[0007] The breeding module comprises a plurality of linked breeding pipes and their associated power devices.
[0008] The breeding tube body contains a breeding spiral, and spiral baffles are installed on both sides of the edge of the breeding spiral along the breeding spiral. The spiral baffles installed on the edge of the breeding spiral are inclined toward the middle of the breeding spiral. The breeding spiral and the side of the baffle close to the breeding spiral are sprayed with a smooth coating, which can ensure that the feed and black soldier fly larvae move gradually forward along the spiral during the rotation of the breeding tube body, and can effectively prevent the black soldier fly larvae from crawling out of the spiral or crawling from the previous spiral to the second spiral.
[0009] Two or three interlocking gears are installed on the outside of the aquaculture tubes to rotate them. During operation, the motor drives the interlocking gears of one aquaculture tube to rotate, and at the same time, the interlocking gears of other parallel aquaculture tubes rotate synchronously, thus achieving synchronous rotation of the entire aquaculture module.
[0010] There are 8 breeding spirals designed inside the breeding tube, which are used for breeding black soldier flies from the first to the eighth day. During the breeding process, the black soldier fly eggs or newly hatched larvae are first released in the first pitch of the breeding tube. The larvae are gradually rotated from the spiral where the release port is located to the tail spiral through the intermittent rotation of the breeding tube, which rotates one pitch every day. During the spiral rotation process, the black soldier flies gradually grow from newly hatched larvae to harvestable black soldier flies. After rotating one pitch, the contents such as black soldier fly larvae in the first pitch are transferred to the second spiral, and the empty first spiral continues to release black soldier fly eggs or newly hatched larvae, thereby realizing the automated and continuous breeding of black soldier flies.
[0011] The outer wall of the last spiral of the breeding tube body is a screen structure, which can achieve preliminary screening of fresh worms, worm feces and a small amount of remaining feed during the rotation of the breeding tube body and the crawling of black soldier flies, thereby obtaining fresh black soldier flies with less impurities.
[0012] The screening device primarily consists of a vibrating drum screen installed below the end of the aquaculture tube. After the black soldier flies complete their initial screening on the eighth spiral, they rotate through the aquaculture tube and fall into the vibrating drum screen below, where they are completely screened, free of fresh insects, excrement, and a small amount of remaining feed. A vibrating screen is mounted above the drum screen, allowing the screens on the drum's sidewalls to vibrate simultaneously during the screening process, improving screening efficiency and completely separating the black soldier flies from impurities.
[0013] The feeding pipe and its attached feeding hole are mainly included in the feeding device. The feeding pipe is used to supply the feed in the breeding pipe body. The feeding pipe is penetrated in the middle of the breeding pipe body, and the feed is transported by the external feeding bin and pressure pump. The feeding pipe is provided with a feeding hole above each breeding spiral. The feeding hole above the spiral is gradually increased as the feeding pipe is continuously inserted from the first spiral to the eighth spiral. The regular change of the feeding hole can effectively realize the normal supply of the required feed for each spiral of the black soldier fly, and avoid the waste of feed caused by excessive or insufficient feeding.
[0014] The control system includes a lamp tube control unit, a temperature and humidity control unit and a breeding pipe body rotation control unit integrated in the PLC control circuit. The patch type LED is installed on the outer wall of the feeding pipe above each breeding spiral, and the temperature and humidity sensor is installed on the outer wall of the feeding pipe in the middle of the breeding pipe body.
[0015] In the process of breeding the black soldier fly, the temperature and humidity data in the breeding pipe body are fed back to the PLC control system in time through the temperature and humidity sensor. When the temperature and humidity data are not suitable for the growth of the black soldier fly, the air in the breeding pipe body is replaced by starting the air blower or air extractor outside the breeding pipe body, so as to control the temperature and humidity in the breeding pipe body.
[0016] The patch type LED installed on the outer wall of the feeding pipe. The spectral characteristics of the patch type LED above each breeding spiral are set according to the illumination requirements of different growth stages of the black soldier fly, and the illumination intensity of each patch type LED can be individually controlled.
[0017] The automatic black soldier fly breeding device designed in the application can realize efficient and continuous breeding of the black soldier fly by controlling the breeding environment and feeding, and has the advantages of high automation degree, high space utilization rate, continuous feeding of eggs or newly hatched larvae, continuous recovery of adult insects and the like.

DETAILED DESCRIPTION
[0019] Implementation Case 1 The intelligent breeding system for black soldier flies designed by the present invention is now further explained in conjunction with the accompanying drawings. It should be pointed out that this specific implementation case is only used as an application explanation of the intelligent breeding system for black soldier flies designed by the present invention, and does not impose any form of limitation on the content of the claims of the present invention. All types of designs derived from the creation of the present invention should be protected by the present invention.
[0020] The directional terms such as “up, down, left, right” in this embodiment are only used to indicate the positions of the components in the accompanying drawings and do not constitute a limitation on their actual application positions.
[0021] Combine Figure 1 A black soldier fly intelligent breeding system, the basic components include a breeding pipe body 3, a feeding pipe 14, a motor 7 and a vibrating drum screen 10.
[0022] The outer wall of the breeding tube body 3 is installed with 2-3 linkage gears 6, one of which is directly connected to the motor 7 to drive the rotation of the breeding tube body 3. In actual application, the number of parallel breeding tube bodies 3 can be changed according to specific needs to achieve mutual coupling of the linkage gears 6. The motor power can be adjusted according to actual needs, so that one motor 7 can drive the rotation of multiple breeding tube bodies 3, thereby improving the efficiency and scale of black soldier fly breeding. Under normal circumstances, the motor 7 drives the breeding tube body 3 to rotate one pitch per day, and the black soldier fly larvae in each breeding spiral gradually move toward the outlet. In special circumstances, such as when the interior of the breeding tube body 3 needs to be cleaned regularly, the motor 7 can drive the breeding tube body 3 to rotate continuously, and the interior of the breeding tube body can be cleaned in a short time.
[0023] The eighth breeding spiral 5 on the far right of the breeding tube body 3 is configured as a screen outer wall 9. When the black soldier flies in the breeding tube body are cultured to the eighth day, the black soldier fly larvae are basically grown into harvestable fresh insects. The outer wall of the last breeding spiral 5 is configured as a mesh so that the insect feces accumulated in the breeding spiral 5 can be discharged from the breeding spiral 5 in time, thereby realizing the preliminary screening of black soldier flies and impurities and reducing the difficulty of subsequent screening.
[0024] The feeding pipe 14 extends deep into the interior of the culture tube 3. Through the coordinated use of the feed hopper 2, pressure pump 1, and metering device, quantitative feed delivery is achieved. A feeding port 15 is located above the feeding pipe 14, directly above each culture spiral 5. The inner diameter of the feeding port 15 gradually increases from the first to the eighth culture spiral. This ensures that the feed provided to the black soldier fly larvae cultured in the culture spiral 5 directly below each feeding port is essentially sufficient to meet their growth needs.
[0025] A vibrating drum screen 10 is installed on the right side of the aquaculture tube. After the black soldier flies in the rightmost aquaculture spiral have completed their final breeding and initial screening, the contents of the aquaculture spiral enter the vibrating drum screen 10 to complete the screening of fresh insects and impurities. During operation, the vibrating drum screen uses a vibration device installed on the screen to improve screening efficiency. Fresh insects and insect feces are collected separately in the fresh insect collection tray 11 and the insect feces collection tray 12.
[0026] A SMD LED is installed on the feeding pipe 14 directly above each breeding spiral 5 to provide the lighting needs of the black soldier fly during its growth process. A temperature sensor and a humidity sensor are installed on the feeding pipe in the middle of the fourth to fifth breeding spirals to provide timely feedback on the humidity and temperature information inside the breeding tube body and to complete the environmental control inside the breeding tube body in a timely manner through the PLC control system.
[0027] Combine Figure 2 A breeding spiral 5 is embedded in the breeding tube body 3, and spiral baffles 4 inclined toward the middle of the spiral are installed on both sides of the breeding spiral 5. A smooth coating is coated on the inner wall of the breeding spiral and the surface of the spiral baffle 4 close to the breeding spiral, which can improve the transfer efficiency of the breeding spiral contents during the rotation of the breeding tube body and prevent black soldier fly larvae from crossing the breeding spiral.
[0028] During the black soldier fly farming process, newly hatched black soldier fly larvae are first placed in the first spiral on the left side of the farming tube 3. The feed is fed into the feeding pipe 14 through the combined action of the feed hopper 2 and the pressure pump 1. From there, the feed is delivered to each farming spiral through the feeding holes 15 according to a predetermined design. In the early stages of black soldier fly farming, the feeding holes directly above the farming spirals without black soldier flies are closed. Once black soldier fly larvae are introduced into the farming spirals, the feeding holes are opened via the PLC control system.
[0029] Newly hatched black soldier fly larvae are placed in the first breeding spiral on the left side of the breeding tube body. After one day of breeding, the breeding tube body 3 is driven by the motor 7 to rotate one pitch, and the black soldier fly larvae in the first breeding spiral are transferred along the breeding spiral into the second spiral. The larvae are then placed in the first breeding spiral again, and so on. After the eighth day, the first released black soldier fly falls from the breeding tube body 3 into the vibrating drum screen 10, thereby completing the automated and continuous breeding of black soldier flies.
[0030] After the black soldier flies and impurities enter the vibrating drum screen 10, screening is completed and the fresh black soldier flies and impurities are collected by the fresh insect collecting tray 11 and the insect excrement collecting tray 12 respectively. The collected fresh insects are used as black soldier fly products and the insect excrement is used as fertilizer.
[0031] During the black soldier fly breeding process, the light environment is regulated by controlling the light intensity of the SMD LED through the PLC control system. The temperature and humidity are regulated by temperature and humidity sensors and supporting exhaust fans and blowers. The environment inside the breeding tube can be controlled according to the growth needs of the black soldier flies to ensure efficient breeding of black soldier flies.
[0032] The automated black soldier fly breeding device of the present invention realizes automated and continuous breeding of black soldier flies through the above method, with high breeding efficiency, high space utilization and low cost.
[0033] Implementation Case 2 The automated black soldier fly breeding device with multiple breeding tubes connected to each other according to the present invention will now be further explained.
[0034] Combine Figure 3 and Figure 4 The black soldier fly intelligent breeding system designed by the present invention can expand the breeding scale by connecting multiple breeding pipes in parallel. Figure 3 The automated breeding device is composed of two rows of three parallel breeding tubes. Its characteristic is that when the motor 7 drives one of the breeding tubes to rotate, it can drive the other parallel breeding tubes to rotate in conjunction, so that each breeding tube rotates one pitch per day.
[0035] In the device described in this embodiment, six aquaculture tubes share a single feed hopper 2. Feed from the feed hopper 2 is delivered to each tube's feeding pipe via an independent pressure pump 1 at the front end of each tube. The rear ends of the tubes share a screening system, including an enlarged vibrating drum screen 10, a fresh insect collection tray 11, and an insect feces collection tray 12. This reduces the complexity of the device while improving the efficiency of screening and fresh insect collection.
[0036] Combine Figure 4 In order to improve the working efficiency of the control system, in this implementation case, the row of breeding pipes can use a shell to complete the sealing of the middle part, and a baffle is installed on the plane where the front end of the first breeding spiral is located, which can realize the sealing of the breeding pipe combination, thereby improving the working efficiency of the control system, reducing the risk of scratches caused by the rotation of the linkage gear, and improving the appearance of the device.
[0037] In addition to the parallel connection method of the breeding tubes in this embodiment, the automated black soldier fly breeding device designed by the present invention can also be installed in parallel in other ways according to the actual production requirements and the spatial characteristics of the device installation. Similar equipment assembled by changes in other installation methods should also be protected by the present invention.
