Abstract
Description
Technical Field
[0001] The present invention relates to the field of insect breeding, and in particular to a black soldier fly layered breeding device. Background Art
[0002] As a resource insect with important economic value, the larvae of black soldier flies are rich in protein, fat and various trace elements. They can not only be used as high-quality feed for aquatic products, livestock and poultry, but also can achieve the reduction and harmless treatment of solid waste by feeding on organic waste. They have broad application prospects in the fields of circular agriculture and ecological environmental protection. At present, traditional black soldier fly farming mostly adopts single-layer or multi-layer stacked breeding boxes. The larvae grow together in the same space, and manual sorting of larvae of different ages is required. There are problems such as high labor intensity, low sorting efficiency, and damage to larvae. This leads to the process of breeding black soldier flies. After each batch is bred, the machine must be stopped to take out the black soldier flies in the same batch for sorting. However, the growth rate of different individual black soldier flies in the same environment is different. If the growth cycle of a longer individual is used as the breeding cycle, the breeding time will be extended, and the black soldier fly larvae grow slowly in the later stage, and the return The reporting rate will be greatly reduced. If the growth cycle of most individuals is used as the breeding cycle, some black soldier flies have not yet reached the designated larval stage and need to be manually sorted or directly recovered. It is impossible to accurately recover the late larvae. Although the existing technology has made certain improvements, many problems still exist. For example, the patent with publication number TWM583195U discloses an automated breeding device for black soldier flies. Although this device can realize the automatic recovery of black soldier flies, it cannot control the age and size of the recovered larvae, and cannot accurately recover large and old larvae. Summary of the Invention
[0003] (1) Technical problems solved
[0004] In response to the shortcomings of the prior art, the present invention aims to provide a stratified breeding device for black soldier flies, which solves the problems existing in the prior art. By taking advantage of the different sensitivities of larvae to sound, light, and vibration signals at different age stages, weak light + low-frequency vibration (simulating slight soil disturbance) is used between young and old larvae. Because young larvae are extremely photophobic and gather in the dark core area, while middle-aged larvae have enhanced tolerance to weak light and need to explore the edge of the feed to feed. The weak light area becomes their active area. Therefore, the middle-aged larvae will move outward and gather, and are transported to the second-layer breeding box by the stratified lifting mechanism. In the second-layer breeding box, the old larvae are in the pre-pupae stage. The larvae at this stage have reduced sensitivity to light and enhanced chemotaxis (seeking dry pupation sites). The strong light area simulates the ground surface, guiding them to move toward the stratified lifting mechanism, separating the middle-aged larvae from the old larvae. The old larvae are lifted to the highest layer by the lifting mechanism.
[0005] (2) Technical solution
[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a black soldier fly stratified breeding device, comprising a stratified breeding box, a stratified lifting mechanism installed on the side of the stratified breeding box; the stratified breeding box is a place for breeding black soldier fly larvae, and the stratified lifting mechanism is used to lift the black soldier fly larvae separated from the stratified breeding box to the next breeding box.
[0007] The tiered aquaculture box includes a frame with a first vibration-damping block fixed to the bottom of the frame, a first aquaculture box placed above the first vibration-damping block, a first support frame fixed to the side of the frame, a second vibration-damping block fixed to the top of the first support frame, a second aquaculture box placed above the second vibration-damping block, a second support frame fixed to the side of the frame, a third vibration-damping block fixed to the top of the second support frame, a third aquaculture box placed above the third vibration-damping block, a vibration-damping rubber fixed to the side of the frame, and a vibrator fixed to the bottom of the vibration-damping rubber. The frame serves as the main support structure of the device, securing the aquaculture boxes, support frames, vibrators, and other components on each layer to ensure overall structural stability. The first vibration-damping block is mounted on the bottom of the frame, with the first aquaculture box fixed to its top. The first vibration-damping block is used to suspend the first aquaculture box in the air to prevent vibrations from the first aquaculture box from being transmitted to the frame when the vibrator is operating, affecting the vibration frequency of the second and third aquaculture boxes. The first support frame and the second support frame are used to be fixed to the side of the frame to support the upper breeding box. The second shock-absorbing block is used to suspend the second breeding box in the air to prevent the second breeding box from transmitting vibrations to the frame during vibration and affecting the vibration frequency of the other two breeding boxes. The third shock-absorbing block is used to suspend the third breeding box in the air to prevent the third breeding box from transmitting vibrations to the frame during vibration and affecting the vibration frequency of the other two breeding boxes. The upper end of the vibrator is connected to the vibration-damping rubber and the lower end is connected to the breeding box. The vibrator is a linear vibration motor that vibrates the breeding box up and down to ensure that the shock-absorbing block isolates the vibration to the greatest extent (the shock-absorbing block mainly relies on its own deformation and damping to alleviate vibration. The up and down vibration method can make the shock-absorbing block deform and reduce vibration to the greatest extent). At the same time, it can ensure the stability of the frame and prevent the resonance caused by the left and right vibrations from reducing the stability of the frame. The lower ends of the three breeding boxes are padded with shock-absorbing blocks to ensure that the breeding boxes can adapt to uneven ground: the ground may be uneven or slightly tilted. The shock-absorbing blocks have certain compressibility and adjustability, and can compensate for a certain tilt angle to keep the bottom of the three breeding boxes level, preventing the older black soldier fly larvae from mistakenly taking the higher side as the ground (older black soldier fly larvae are in the pre-pupae stage and will move to the ground to find a place to pupate) and gathering on the higher side. This will cause the black soldier fly larvae on the other side of the breeding box to crawl a longer distance to reach it, reducing the separation efficiency of larvae at different stages.
[0008] The tiered lifting mechanism consists of a lifting frame placed on the ground, with cylinders fixed to the sides and a drive motor fixed to the bottom. A lead screw is connected to the drive motor, with lead screw holders fixed at each end. A lifting plate is mounted on the lead screw, and a slider is installed inside the lifting plate. The lifting frame serves as the supporting framework for the tiered lifting mechanism, securing the drive motor, lead screw, and other components to ensure the vertical movement of the lifting plate. Cylinders are fixed to the sides of the lifting frame, with two cylinders positioned on each layer. These cylinders operate rapidly, pushing the slider and pushing the black soldier flies in the lifting plate into the breeding tank. The drive motor electrically drives the lead screw, which is fixed to each end of the lead screw. The lead screw mates with threaded holes in the lifting plate to achieve precise up and down movement of the lifting plate.
[0009] A lamp tube is fixed at the lower end of the lifting plate; the lifting plate is installed on the screw, corresponding to each layer of the breeding box, and the lamp tube is installed at the bottom of the lifting plate corresponding to the third breeding box and the second breeding box, and the illumination of the lamp tube at the bottom of the lifting plate corresponding to the second breeding box is a weak light of 50-100 lux, and the illumination of the lamp tube at the bottom of the lifting plate corresponding to the third breeding box is 200-500 lux.
[0010] Blackout curtains are fixed on the sides of the second and third breeding boxes. The blackout curtains are located between the breeding boxes and the lifting plate to block light. They hang down from the bottom of the breeding boxes and leave a 10 cm space for the passage of feed and black soldier fly larvae.
[0011] The first breeding box, the second breeding box and the third breeding box are provided with connecting blocks on the sides, and a connecting port is provided in the connecting blocks; the connecting blocks protrude outward, and the vibrating head of the vibrator is connected to the connecting port. When the vibrator vibrates, it drives the breeding box to vibrate. The vibrator connected to the first breeding box usually vibrates at a small amplitude of 50Hz and is started intermittently (working for 10 minutes and pausing for 20 minutes); the vibrator connected to the second breeding box has a vibration frequency of 100Hz and an amplitude of 1-2mm. This layer of vibration is started every other day, with a vibration time of 10 minutes and a pause of 20 minutes; the vibrator connected to the third breeding box runs for five minutes every half hour, with a vibration frequency of 50Hz.
[0012] The two sides of the first breeding box are tilted downward, and the middle of the third breeding box is tilted downward, and the tilt angles are all 3°-5°; the middle of the first breeding box is convex, the middle of the third breeding box is concave, and the second breeding box is a flat plate. In this way, when the vibrator vibrates, it can assist the black soldier fly larvae to crawl to the side of the first breeding box and enter the lifting plate, and at the same time, the feces of the black soldier fly can be shaken off. Because it cannot be ensured that the black soldier fly larvae entering the third breeding box are all old black soldier fly larvae, the setting of the third breeding box can make the black soldier fly larvae gather in the middle of the breeding box when vibrating, and finally the small-sized black soldier fly larvae are dropped back into the second breeding box through vibration to continue feeding and growing.
[0013] The lift plate is equipped with guide wheels on the side, threaded holes in the plate, and a reset mechanism on the top. The guide wheels work with the lift frame guide rails to reduce lifting friction and ensure smooth movement. The threaded holes engage the lead screw to achieve vertical displacement. The reset mechanism is used to reset the slider.
[0014] The reset mechanism is equipped with a guide block on the side, with a roller installed inside the guide block. A limit plate is fixed to the front end of the guide block, and a guide rod is fixed to the side of the limit plate. A spring is installed on the outside of the guide rod, and a limit screw is screwed into the end of the guide rod. The guide block is fixed to the side of the reset mechanism, providing a guide track for the movement of the slider, ensuring that the slider resets in a straight line, avoiding jamming or wear caused by offset. The roller is installed inside the guide block, creating rolling friction with the contact surface of the slider, greatly reducing the slider's operating resistance. The limit plate limits the distance the slider moves forward after being impacted by the cylinder and provides a mounting base for the spring. The guide rod provides guidance for the spring to push the slider back, ensuring that the direction and angle of the slider will not deviate during reset. It is mounted on the outside of the guide rod and provides the reset force. When the cylinder pushes the slider, the spring is compressed to store elastic potential energy. When the slider's potential energy is exhausted, the spring releases this potential energy to push the slider back. The limit screw ensures that the slider does not fall out of the reset mechanism during reset.
[0015] A guide groove is provided on the side of the slider, and a stepped hole is provided on the side of the slider; the guide groove cooperates with the guide block, and the stepped hole is used to pass the guide rod and insert the spring to ensure that the spring can push the slider.
[0016] The first breeding box is evenly provided with first through-holes with a diameter of 1mm, the second breeding box is evenly provided with second through-holes with a diameter of 5mm, and the third breeding box is evenly provided with third through-holes with a diameter of 10mm. The black soldier fly larvae in the first breeding box are relatively small, and are mainly young and middle-aged larvae. The 1mm through-holes can prevent the black soldier fly larvae from falling to the ground, and the dense through-holes can achieve micro-air circulation to avoid excessive humidity in the bottom layer due to the dense concentration of larvae. The black soldier fly larvae in the second breeding box are middle-aged and old larvae. The 5mm through-holes can prevent normal-sized larvae from falling, while allowing smaller larvae to fall back into the first breeding box. The third breeding box mainly contains old larvae. The 10mm gap ensures that normal-sized old larvae will not fall while allowing small-sized black soldier fly larvae to fall. This arrangement ensures that the black soldier fly larvae in each layer have undergone dual separation by age and size.
[0017] (3) Beneficial effects
[0018] This invention simulates the behavioral responses of black soldier fly larvae at different stages to sound, light, and vibration signals, and constructs an automated layered culture system. The bottom layer uses weak light combined with low-frequency vibration to separate young and middle-aged larvae, and the middle-aged larvae are transferred to the second layer via a lifting mechanism. The second layer uses strong light to simulate the surface environment, guiding the older larvae with enhanced chemotaxis to gather toward the lifting mechanism, where they are automatically grouped with the middle-aged larvae and then moved to the third layer. This device, which requires no manual sorting, relies on the aperture gradient design of the culture box, an inclined diversion structure, and a vibration isolation system to achieve active cross-layer migration and environmental adaptation and growth of larvae. This system overcomes the technical bottlenecks of traditional culture, which often involve high manual intervention, low separation accuracy, and interrupted culture cycles. It significantly improves the efficiency of continuous black soldier fly culture, reduces labor costs, and provides a highly efficient solution for large-scale insect recovery and industrial production of resource insects.

DETAILED DESCRIPTION
[0033] The following is a summary of the examples of the present invention. Figure 1 -Attached Figure 13 A clear and complete description of the technical solutions in the embodiments of the present invention is provided. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0034] The present invention provides a technical solution: a black soldier fly stratified breeding device, comprising a stratified breeding box 1, a stratified lifting mechanism 2 is installed on the side of the stratified breeding box 1; the stratified breeding box 1 is a place for breeding black soldier fly larvae, and the stratified lifting mechanism 2 is used to lift the black soldier fly larvae separated from the stratified breeding box 1 to the next breeding box.
[0035] The layered breeding box 1 includes a frame 101, a first vibration damping block 102 is fixed to the bottom of the frame 101, a first breeding box 103 is placed on the upper end of the first vibration damping block 102, a first supporting frame 104 is fixed to the side of the frame 101, a second vibration damping block 105 is fixed to the upper end of the first supporting frame 104, a second breeding box 106 is placed on the upper end of the second vibration damping block 105, a second supporting frame 107 is fixed to the side of the frame 1, a third vibration damping block 108 is fixed to the upper end of the second supporting frame 107, a third breeding box 109 is placed on the upper end of the third vibration damping block 108, a vibration damping rubber 110 is fixed to the side of the frame 1, and a vibrator 111 is fixed to the lower end of the vibration damping rubber 110; the frame 101 serves as the main supporting structure of the device, fixing components such as the breeding boxes, support frames and vibrators 111 on each layer to ensure the stability of the overall structure. A first shock-absorbing block 102 is mounted at the bottom of the frame 101, with the first culture box 103 secured to its upper end. This block 102 suspends the first culture box 103, preventing vibrations from the first culture box 103 from being transmitted to the frame 101 when the vibrator 111 is operating, potentially affecting the vibration frequencies of the second and third culture boxes 106 and 109. A first support frame 104 and a second support frame 107 are secured to the sides of the frame 101, supporting the upper culture boxes. A second shock-absorbing block 105 suspends the second culture box 106, preventing vibrations from the second culture box 106 from being transmitted to the frame 101 and affecting the vibration frequencies of the remaining two culture boxes. A third shock-absorbing block 108 suspends the third culture box 109, preventing vibrations from the third culture box 109 from being transmitted to the frame 101 and affecting the vibration frequencies of the remaining two culture boxes. The upper end of the vibrator 111 is connected to the vibration-damping rubber 110, and the lower end is connected to the breeding box. The vibrator 111 is a linear vibration motor, which vibrates the breeding box up and down, ensuring that the shock-absorbing block isolates vibration to the greatest extent (the shock-absorbing block mainly relies on its own deformation and damping to alleviate vibration, and the up and down vibration method can enable the shock-absorbing block to deform and reduce vibration to the greatest extent). At the same time, it can ensure the stability of the frame 101 and prevent the resonance caused by the left and right vibrations from reducing the stability of the frame 101. The lower ends of the three breeding boxes are padded with shock-absorbing blocks to ensure that the breeding boxes can adapt to uneven ground: the ground may be uneven or slightly tilted. The shock-absorbing blocks have certain compressibility and adjustability, and can compensate for a certain tilt angle to keep the bottom of the three breeding boxes level, preventing the older black soldier fly larvae from mistakenly taking the higher side as the ground (older black soldier fly larvae are in the pre-pupae stage and will move to the ground to find a place to pupate) and gathering on the higher side. This will cause the black soldier fly larvae on the other side of the breeding box to crawl a longer distance to reach it, reducing the separation efficiency of larvae at different stages.
[0036] The layered lifting mechanism 2 includes a lifting frame 201 placed on the ground, a cylinder 202 is fixed to the side of the lifting frame 201, a driving motor 203 is fixed to the bottom of the lifting frame 201, a lead screw 204 is connected to the driving motor 203, lead screw seats 205 are fixed at both ends of the lead screw 204, a lifting plate 206 is installed on the lead screw 204, and a slider 207 is installed in the lifting plate 206; the lifting frame 201 serves as the supporting frame of the layered lifting mechanism 2, fixing the driving motor 203, the lead screw 204 and other components to ensure the vertical movement of the lifting plate. The cylinder 202 is fixed on the side of the lifting frame 201, and two cylinders 202 are arranged on each layer. The actuation speed of the cylinder 202 is relatively fast, pushing the slider 207 to move, pushing the black soldier flies in the lifting plate 206 into the breeding box, and the driving motor 203 rotates through the electric drive screw 204. The screw seat 205 is fixed at both ends of the screw 204. The screw 204 cooperates with the threaded hole 2062 of the lifting plate 206 to realize the precise up and down movement of the lifting plate 206.
[0037] A lamp tube 208 is fixed to the lower end of the lifting plate 206; the lifting plate 206 is installed on the screw 204, corresponding to each layer of the breeding box, and the lamp tube 208 is installed at the bottom of the lifting plate 206 corresponding to the third breeding box 109 and the second breeding box 106, and the illumination of the lamp tube at the bottom of the lifting plate 206 corresponding to the second breeding box 106 is a weak light of 50-100 lux, and the illumination of the lamp tube at the bottom of the lifting plate 206 corresponding to the third breeding box 109 is 200-500 lux.
[0038] A blackout curtain 112 is fixed on the side of the second breeding box 106 and the third breeding box 109; the blackout curtain 112 is located between the breeding box and the lifting plate 206, used to block light, hangs down from the bottom of the breeding box, and leaves a 10 cm space for passing feed and black soldier fly larvae.
[0039] The first breeding box 103, the second breeding box 106 and the third breeding box 109 are provided with connecting blocks 113 on the side, and a connecting port 114 is provided in the connecting block 113; the connecting block 113 protrudes outward, and the vibrating head of the vibrator 111 is connected to the connecting port 114. When the vibrator 111 vibrates, it drives the breeding box to vibrate. The vibrator 111 connected to the first breeding box 103 usually vibrates to maintain a small amplitude of 50Hz and is started intermittently (working for 10 minutes and pausing for 20 minutes); the vibrator 111 connected to the second breeding box 106 has a vibration frequency of 100Hz and an amplitude of 1-2mm. This layer of vibration is started every other day, and the vibration duration is 10 minutes and 20 minutes. The vibrator 111 connected to the third breeding box 109 runs for five minutes every half an hour, and the vibration frequency is 50Hz.
[0040] The two sides of the first breeding box 103 are tilted downward, and the middle of the third breeding box 109 is tilted downward, and the inclination angles are all 3°-5°; the middle of the first breeding box 103 is protruding, the middle of the third breeding box 109 is concave, and the second breeding box 106 is a flat plate. In this way, when the vibrator 111 vibrates, it can assist the black soldier fly larvae to crawl to the side of the first breeding box 103 and enter the lifting plate 206. At the same time, the feces of the black soldier fly can be shaken off. Because it cannot be ensured that the black soldier fly larvae entering the third breeding box 109 are all old black soldier fly larvae, the setting of the third breeding box 109 can make the black soldier fly larvae gather in the middle of the breeding box when vibrating, and finally the small black soldier fly larvae are dropped back into the second breeding box 106 by vibration to resume feeding and growth.
[0041] Lifting plate 206 is provided with guide wheels 2061 on its side, threaded holes 2062 within it, and a reset mechanism 2063 on its upper end. Guide wheels 2061 cooperate with the guide rails of lift frame 201 to reduce lifting friction and ensure smooth movement. Threaded holes 2062 engage with lead screw 201 to achieve vertical displacement. Reset mechanism 2063 is used to reset slider 207.
[0042] A guide block 2064 is mounted on the side of the reset mechanism 2063, with a roller 2065 installed inside. A limit plate 2066 is fixed to the front end of the guide block 2064, and a guide rod 2067 is fixed to the side of the limit plate 2066. A spring 2068 is mounted on the outside of the guide rod 2067, and a limit screw 2069 is screwed into the end of the guide rod 2067. The guide block is fixed to the side of the reset mechanism 2063, providing a guide track for the movement of the slider 207, ensuring that the slider resets in a straight line and avoiding jamming or wear caused by deviation. The roller 2065 is installed inside the guide block 2064, creating rolling friction with the contact surface of the slider 207, greatly reducing the operating resistance of the slider 207. Limit plate 2066 limits the forward movement of slider 207 after being impacted by cylinder 202 and provides a mounting base for spring 2068. Guide rod 2067 guides the spring 2068 in pushing slider 207 back, ensuring that the slider 207 does not shift in direction or angle during reset. It fits over guide rod 2067 and provides the reset force. When cylinder 202 pushes the slider, spring 2068 is compressed and stores elastic potential energy. When the potential energy of slider 207 is depleted, spring 2068 releases this energy, pushing slider 207 back into its original position. Limit screw 2069 ensures that slider 207 does not fall out of reset mechanism 2063 during reset.
[0043] A guide groove 2071 is provided on the side of the slider 207, and a stepped hole 2072 is provided on the side of the slider 207; the guide groove 2071 cooperates with the guide block 2064, and the stepped hole 2072 is used to pass the guide rod 2067 and insert the spring 2068 to ensure that the spring 2068 can push the slider 207.
[0044] The first breeding box 103 is uniformly provided with first through-holes 1031 having a diameter of 1 mm, the second breeding box 106 is uniformly provided with second through-holes 1061 having a diameter of 5 mm, and the third breeding box 109 is uniformly provided with third through-holes 1091 having a diameter of 10 mm. The black soldier fly larvae in the first breeding box 103 are relatively small, primarily young and middle-aged larvae. The 1 mm through-holes prevent the black soldier fly larvae from falling to the ground, and the dense through-holes allow for micro-circulation of air, preventing excessive humidity on the bottom layer due to the dense concentration of larvae. The black soldier fly larvae in the second breeding box 106 are mainly middle-aged and older larvae. The 5 mm through-holes prevent normal-sized larvae from falling while allowing smaller larvae to fall back into the first breeding box 103. The third breeding box 109 mainly contains older larvae. The 10 mm gap can ensure that older larvae of normal size will not fall while allowing small black soldier fly larvae to fall. This setting can ensure that the black soldier fly larvae in each layer are dually separated by age and size.
[0045] The black soldier fly stratified breeding device divides the breeding box and the lifting plate 206 into two areas with different lighting through the black soldier fly larvae 112. When the black soldier fly larvae are placed in the first breeding box 103, the vibrator 111 starts working. The lighting and vibration settings of the first breeding box 103 mainly play the following roles:
[0046] 1. Young larvae gather in the dark core area due to their strong photophobia, so they will remain in the dark area at the center of the first breeding box 103.
[0047] 2. The middle-aged larvae have enhanced tolerance to weak light and need to explore the edge of the feed to feed. The weak light area becomes their active area, and the vibration and the slope of the first breeding box 103 accelerate the migration of the middle-aged larvae to the edge, so that they enter the lifting plate 206 on the side and enter the second breeding box 106 through lifting.
[0048] When the black soldier fly larvae enter the second breeding box 106, the vibrator 111 on the second breeding box 106 starts to vibrate. The vibration mode of the vibrator on the breeding box is a vibration frequency of 100 Hz and an amplitude of 1-2 mm. The vibration is started every other day, and the vibration duration is 10 minutes and 20 minutes. The set light and vibration have the following functions:
[0049] 1. For middle-aged larvae, their food intake increases greatly and they enter a period of overeating. Vibration can promote the uniform distribution of black soldier fly larvae and food, ensure the feeding efficiency of black soldier fly larvae, and accelerate their growth rate.
[0050] 2. For older larvae, they are large in size and have strong mobility. They can move away from the strong vibration source by peristalsis. The vibration simulates the soil loosening signal, prompting the pre-pupae larvae to escape from the vibration area to the outside and gather towards the non-vibrating lifting plate 206.
[0051] 3. The older larvae are pre-pupae, and their sensitivity to light decreases, but their chemotaxis (seeking a dry place to pupate) increases. The strong light area simulates the ground surface, guiding them to move toward the lifting plate 206 where the strong light is irradiated from the outside.
[0052] The older larvae continue to pass through the layered lifting mechanism 2 and enter the third breeding box 109 on the top floor.
[0053] At the same time, the vibrator 111 cooperates with each breeding box to produce the following effects:
[0054] 1. When the larvae are not big enough and are driven into the breeding box on the upper layer by sound, light and vibration, the larvae will fall back into the breeding box on the next layer through vibration and the holes at the bottom of the breeding box, realizing double-layer filtration and ensuring that the larvae entering the top layer can be directly recycled.
[0055] 2. The feed of this device is directly put into the third breeding box 109, and the vibration can make the feed fall evenly into the second breeding box 106 and the first breeding box 103. Because the holes of each breeding box are different, the feed particles at the bottom are the smallest and the feed particles at the top are the largest, ensuring that the young larvae at the bottom can eat quickly.
[0056] 3. Vibration can accelerate the evaporation of moisture in the feed and promote the flow of oxygen, ensuring the dryness of the breeding box, preventing the larvae from being trapped in a humid environment, and ensuring the effectiveness of sound, light and vibration stratification.
[0057] 4. Prevent feed from accumulating in the first breeding box 103. The vibration and the shape of the first breeding box 103 ensure that the feed can be lifted into the second breeding box 106 along with the larvae by the layered lifting mechanism 2, ensuring that the feed in the second breeding box 106 is the largest and that the huge feed demand of the middle-aged larvae can be met.
[0058] Working principle:
[0059] First, the black soldier fly larvae are placed on the first breeding box 103, and the feed is placed on the third breeding box 109. The feed is evenly distributed on the three breeding boxes by vibration. After three days of breeding, conventional vibration is started. The first breeding box 103 attracts the middle-aged larvae to the lifting plate 206 outside the first breeding box 103 by vibration and the outside light. At the same time, the second breeding box 106 drives and attracts the older larvae to the outer lifting plate 206 by the outside light and vibration. The layered lifting mechanism 2 is operated once a day, and the lifting plate 206 is driven upward to the side of the breeding box on the upper layer by the lead screw 204. After that, the cylinder 202 pushes the slider 207 to push the feed and black soldier fly larvae in the lifting plate 206 into the breeding box. After that, the lifting plate 206 returns to the original side of the breeding box to continue to accommodate the larvae to gather. Vibration and light are used to attract the fully grown larvae on each layer. By lifting layer by layer, it is ensured that the older larvae gather in the third breeding box 109.
