Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, specifically to an automatic egg scraper for black soldier fly farming. Background Technology

[0002] Black soldier flies are saprophytic insects belonging to the family genus *Brachys*. Due to their efficient conversion of organic waste into high-value animal protein feed, they have been widely used in large-scale farming in recent years. Currently, a common method for collecting black soldier fly eggs involves using a stacked wooden board structure, with wooden slats or thumbtacks used to create oviposition gaps. After the black soldier flies have laid their eggs in these gaps, each board must be manually removed, and the eggs scraped off using a scraper or brush. While this method is simple in structure, the gap height is limited by the size of the thumbtacks or wooden slats, making precise adjustment difficult and potentially leading to poor oviposition results in some areas. Manual egg scraping is inefficient, especially in large-scale farms, requiring significant manpower and impacting production efficiency. Furthermore, the boards require frequent replacement and cleaning, resulting in poor reusability and increased equipment maintenance costs over the long term.

[0003] To address the aforementioned issues, Chinese patent (authorization announcement number CN212728502U) discloses a rotating oviposition collection device. This patent involves a rotating oviposition device pivotally connected to a frame, driven by a hand crank. The bristles of the oviposition scraper penetrate into the gaps in the oviposition plate, scraping away insect eggs as the device rotates. The eggs ultimately fall onto the mesh cover of the attractant box for collection. Compared to traditional wooden board structures, this device achieves automated operation, fixes the oviposition gaps, and ensures efficient egg collection and reusability. However, this device still has shortcomings in practical applications:

[0004] 1. The rotating spawner has a single driving method, mostly manual operation, which is inefficient and cannot meet the needs of large-scale farms for high efficiency and automation;

[0005] 2. The scraped-off insect eggs were not effectively guided and were easily scattered or blocked inside the device, affecting the collection effect;

[0006] 3. The connections between the components are loose, failing to form a stable integrated structure, resulting in poor equipment reliability and maintainability. Summary of the Invention

[0007] To address the aforementioned problems, an automatic egg-scraping machine for black soldier fly farming is provided. This machine utilizes egg-scraping components mounted on both sides of the drive unit, which slide along the height of the egg-laying box. These components further scrape away any remaining eggs at the edges of the egg-laying plates, ensuring complete detachment of all black soldier fly eggs within the egg-laying boxes, thus achieving efficient egg collection. The drive unit enables relative sliding movement between the egg-laying plates of the first and second egg-laying frames. Combined with the assistance of the egg-scraping components, the equipment automatically detaches and collects black soldier fly eggs, significantly reducing manual intervention and operational complexity, optimizing the production process, and improving production efficiency.

[0008] To address the problems of existing technologies, this invention provides an automatic egg-scraping machine for black soldier fly farming, comprising a frame and a collection box and an egg-laying box mounted on the frame. The egg-laying box contains a first egg-laying frame and a second egg-laying frame. The first egg-laying frame is fixedly connected to the egg-laying box; the second egg-laying frame is slidably mounted within the egg-laying box. Both the first and second egg-laying frames are equipped with multiple egg-laying plates, all spaced vertically apart, with gaps between adjacent egg-laying plates for black soldier flies to lay eggs. The two spawning frames have staggered spawning plates. A drive box is installed on the frame, and a drive component is installed inside the drive box to move the second spawning frame, so that the spawning plates on the second spawning frame can move relative to the spawning plates of the first spawning frame, thereby realizing the detachment and collection of black soldier fly eggs on the spawning plates. On both sides of the spawning box on the drive box, there are egg scraping components that can slide along the height direction of the spawning box. The two egg scraping components are used to scrape the end faces of the first and second spawning frames that are far apart from each other.

[0009] Preferably, the two egg-scraping components are arranged in a mirror-symmetrical manner on the drive box, and a distance matching the egg-laying box is left between the two egg-scraping components. The egg-scraping component includes a support frame, a cleaning brush and two support arms. The support frame is fixedly connected to the drive box, and the two support arms are rotatably located at both ends of the support frame. The cleaning brush is fixedly connected between the two support arms, and the support arms are elastic telescopic structures.

[0010] Preferably, the top surface of the support frame is inclined, and two pulleys are provided at both ends of the cleaning brush. Both pulleys are made of rubber, and two limiting grooves that match the pulleys are provided on the top surface of the support frame.

[0011] Preferably, two guide frames are provided between the two egg scraping components. The two guide frames are mirror-symmetrical and located at both ends of the support frame. Both ends of the two guide frames are provided with inclined guide grooves, and the guide grooves of the two guide frames are inclined towards one side of the support frame. Both ends of the support frame are provided with mounting boxes that are fixedly connected to the two guide frames. One of the mounting boxes is provided with a rotary drive motor. The support frame is provided with a drive shaft for driving the support arm to rotate, and the drive shaft is connected to the rotary drive motor.

[0012] Preferably, the drive assembly includes two swing arms, which are mirror-symmetrical and rotatable relative to each other within the drive housing. Each swing arm is provided with a drive pin extending along the height direction. The top of the drive housing is provided with an arc-shaped groove that matches the drive pin. The drive pin passes through the arc-shaped groove to limit its movement trajectory. The top of the drive housing is also provided with a positioning pin extending along the vertical direction. The first spawning frame is provided with a first mounting hole that matches the positioning pin, and the second spawning frame is provided with a second mounting hole that matches the positioning pin.

[0013] Preferably, the drive assembly further includes an electric actuator and two gears. The electric actuator is located inside the drive housing, with one end of the electric actuator hinged to the drive housing. The output shaft of the electric actuator is hinged to the end of one of the swing arms. The two gears are rotatably mounted inside the drive housing, meshing with each other and located between the two swing arms. Each swing arm is provided with an incomplete gear plate, which meshes with the gears on its side.

[0014] Preferably, the interior of the spawning box is provided with a first sliding groove at both ends, and the interior of the second spawning frame is provided with a sliding rail at both ends that matches the first sliding groove.

[0015] Preferably, the first spawning frame is provided with multiple first positioning plates, which are arranged equidistantly along the height direction of the spawning box. The multiple spawning plates are installed between the multiple first positioning plates, and a first positioning post is provided between the multiple first positioning plates. All the first positioning plates are connected and fixed through the first positioning post.

[0016] Preferably, the second spawning frame is provided with multiple second positioning plates, which are arranged equidistantly along the height direction of the spawning box. The multiple spawning plates are installed between the multiple second positioning plates, and second positioning posts are provided between the multiple second positioning plates. All the second positioning plates are connected and fixed through the second positioning posts.

[0017] Preferably, a support shaft is provided on the frame, and the drive box is rotatably mounted on the support shaft.

[0018] The advantages of this invention compared to the prior art are:

[0019] 1. This invention utilizes egg-scraping components mounted on both sides of the drive box, which slide along the height of the spawning box. These components further scrape away residual eggs at the edges of the spawning plates, ensuring complete detachment of all black soldier fly eggs within the spawning boxes, thus achieving efficient egg collection. The drive components enable relative sliding movement between the spawning plates of the first and second spawning frames. Combined with the assistance of the egg-scraping components, the equipment automatically detaches and collects black soldier fly eggs, significantly reducing manual intervention and operational complexity, optimizing the production process, and improving efficiency. The relative movement between the spawning plates efficiently removes most of the black soldier fly eggs, while the egg-scraping components further clean up residual eggs at the edges of the spawning plates, ensuring comprehensive egg collection and effectively reducing waste. The automated operation of the equipment not only reduces labor and time costs but also provides higher economic benefits for aquaculture enterprises.

[0020] 2. This invention, through the elastic telescopic structure of the support arm, can adapt to changes in the side wall shape and pressure of the spawning box, achieving efficient cleaning of egg residue in different locations. Through the synergistic action of the cleaning brush and the support frame, residual black soldier fly eggs can automatically collect on the support frame, eliminating the need for complex operations. Subsequent retrieval steps can be completed with simple tools, significantly reducing labor intensity. The two mirror-symmetrically arranged egg-scraping components can act simultaneously on both sides of the spawning box, improving scraping efficiency. Simultaneously, the two egg-scraping components also serve to limit the movement of the spawning box, facilitating the driving of the second spawning frame within the box after it is placed on the drive unit.

[0021] 3. The drive box can rotate flexibly via the support shaft, thereby driving the rotation of the spawning box. The rotation setting of the spawning box allows the staff to conduct a comprehensive inspection of the inside and outside of the spawning box without disassembling the equipment, quickly identify and solve potential problems, reduce unnecessary losses in the breeding process, and enable the staff to complete the operation without having to move the spawning box, effectively reducing labor intensity and improving the convenience and efficiency of operation.

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 4 , Figures 6 to 9As shown: An automatic egg-scraping machine for black soldier fly farming includes a frame 1 and a collection box 11 and an egg-laying box 2 mounted on the frame 1. The egg-laying box 2 contains a first egg-laying frame 21 and a second egg-laying frame 22. The first egg-laying frame 21 is fixedly connected to the egg-laying box 2. The second egg-laying frame 22 is slidably mounted inside the egg-laying box 2. Both the first and second egg-laying frames 21 and 22 are equipped with multiple egg-laying plates 211, all spaced vertically, with gaps between adjacent egg-laying plates 211 for black soldier flies to lay eggs. 1. The rack is staggered; a drive box 12 is provided on the frame 1, and a drive component 121 is provided inside the drive box 12 to move the second spawning rack 22, so that the spawning plate 211 on the second spawning rack 22 can move relative to the spawning plate 211 of the first spawning rack 21, thereby realizing the detachment and collection of black soldier fly eggs on the spawning plate 211; on both sides of the spawning box 2, there are egg scraping components 13 that can slide along the height direction of the spawning box 2. The two egg scraping components 13 are respectively used to scrape the end faces of the first spawning rack 21 and the second spawning rack 22 that are far apart from each other.

[0037] Before egg collection, the spawning box 2 is placed in the breeding area. Black soldier flies will lay eggs on the egg-laying plates 211 of the first and second spawning frames 21 and 22 under the influence of an inducer. After the black soldier flies have finished laying eggs, the spawning box 2 is placed on the drive box 12. The drive assembly 121 inside the drive box 12 will cause the second spawning frame 22 inside the spawning box 2 to slide. Since the first spawning frame 21 is fixedly connected to the spawning box 2, the egg-laying plates 211 of the second spawning frame 22 can move relative to the egg-laying plates 211 of the first spawning frame 21 during the sliding process.

[0038] By alternating and moving the ovipositor plates 211 of the first ovipositor 21 and the second ovipositor 22, the eggs attached to the surface of the ovipositor plates 211 can be effectively scraped off until the black soldier fly eggs fall off from the opposite ends of the first ovipositor 21 and the second ovipositor 22 and fall into the collection box 11, thus completing the collection of black soldier fly eggs.

[0039] Because black soldier fly eggs are highly adhesive, some eggs tend to remain on the end faces of the first and second oviposition frames 21 and 22 when scraped away during collection. To address this issue, egg-scraping components 13 are installed on both sides of the drive box 12, capable of sliding along the height of the oviposition box 2. These components 13 further scrape away any remaining eggs at the edges of the oviposition plate 211, ensuring that all black soldier fly eggs in the oviposition box 2 are completely removed, thus achieving efficient collection of black soldier fly eggs.

[0040] The relative sliding motion between the oviposition plates 211 of the first and second oviposition frames 21 and 22 is achieved through the drive component 121. Combined with the assistance of the egg-scraping component 13, the equipment can automatically complete the detachment and collection of black soldier fly eggs, significantly reducing manual intervention and operational complexity, optimizing the production process, and improving production efficiency. The relative motion between the oviposition plates 211 efficiently scrapes away most of the black soldier fly eggs, while the egg-scraping component 13 further removes residual eggs from the edges of the oviposition plates 211, ensuring comprehensive collection of black soldier fly eggs and effectively reducing waste. The automated operation of the equipment not only reduces labor and time costs but also provides higher economic benefits for aquaculture enterprises.

[0041] like Figure 4 , Figures 6 to 11 As shown: Two egg-scraping components 13 are arranged in a mirror-symmetrical manner on the drive box 12. There is a gap between the two egg-scraping components 13 that matches the egg-laying box 2. The egg-scraping component 13 includes a support frame 131, a cleaning brush 132 and two support arms 133. The support frame 131 is fixedly connected to the drive box 12. The two support arms 133 are rotatably located at both ends of the support frame 131. The cleaning brush 132 is fixedly connected between the two support arms 133. The support arms 133 are elastic telescopic structures.

[0042] Two support arms 133 are initially positioned on the support frame 131. When the support arms 133 rotate, their ends abut against the side wall of the spawning box 2. Due to the elastic extension and retraction function of the support arms 133, during rotation, the support arms 133 can adapt to the contact pressure with the side wall of the spawning box 2 and slide along the height direction of the spawning box 2, thereby driving the cleaning brush 132 located between the two support arms 133 to move up and down. Through the scraping action of the cleaning brush 132, the black soldier fly eggs attached to the side end face of the spawning box 2 (i.e., the end faces of the opposite ends of the spawning plates 211 of the first spawning frame 21 and the second spawning frame 22) can be effectively removed. The black soldier fly eggs scraped off by the cleaning brush 132 will fall directly onto the support frame 131. The operator only needs to collect the eggs on the support frame 131 by using a brush (in the prior art, the operator usually manually scrapes the eggs off the side wall of the spawning box 2), simplifying the subsequent processing steps.

[0043] The elastic telescopic structure of the support arm 133 can adapt to changes in the side wall shape and pressure of the spawning box 2, achieving efficient cleaning of egg residue in different locations. Through the synergistic action of the cleaning brush 132 and the support frame 131, the remaining black soldier fly eggs can be automatically collected on the support frame 131 without complicated operations. Subsequent recycling steps can be completed with only simple tools, greatly reducing labor intensity.

[0044] The egg-scraping assembly 13 automates the process, reducing manual intervention and increasing the automation level of the equipment, which is beneficial for efficient management in large-scale farming. By reducing waste caused by egg residue and increasing egg recovery rate, economic benefits are improved while production costs are reduced.

[0045] The two egg-scraping components 13, which are set in a mirror symmetry, can act on both sides of the spawning box 2 at the same time, improving the egg-scraping efficiency. At the same time, the two egg-scraping components 13 can also limit the position of the spawning box 2, so that after the spawning box 2 is placed on the drive box 12, the second spawning rack 22 inside the spawning box 2 can be driven by the drive component 121.

[0046] like Figure 4 , Figures 6 to 11 As shown: The top surface of the support frame 131 is inclined, and two pulleys 1321 are provided at both ends of the cleaning brush 132. Both pulleys 1321 are made of rubber. Two limiting grooves 1311 that match the pulleys 1321 are provided on the top surface of the support frame 131.

[0047] By designing the top surface of the support frame 131 as an inclined structure, gravity can be used to guide the fallen black soldier fly eggs to a designated area, reducing scattering and facilitating recycling by the collection box 11 on the frame 1.

[0048] The rubber material of the pulley 1321 ensures that when the support arm 133 slides in contact with the side wall of the spawning box 2, it can reduce friction and avoid direct contact between the support arm 133 and the spawning box 2, thus preventing damage to the surface of the spawning box 2. At the same time, it enhances the stability of the egg scraping component 13 during the sliding process and ensures the smoothness of the egg scraping process.

[0049] With the matching of the limiting groove 1311 and the pulley 1321, when the support arm 133 rotates to be parallel to the top surface of the support frame 131, the pulley 1321 can be engaged in the limiting groove 1311, ensuring that the support arm 133 remains in a retracted state in the initial state, so that the support arm 133 can be stably placed on the support frame 131, preventing the support arm 133 from loosening when not in use, and facilitating equipment storage and transportation.

[0050] By rotating the support arm 133 again, the pulley 1321 is released from the limiting groove 1311. The support arm 133 can then slide along the side wall of the spawning box 2 via the pulley 1321, driving the cleaning brush 132 to perform the egg scraping operation. This makes the operation simple, reduces manual intervention, and improves the automation performance of the equipment.

[0051] Meanwhile, the setting of the limiting groove 1311 enables the two egg scraping components 13 to limit the egg-laying box 2, which facilitates the transmission of the drive component 121 and avoids the support arm 133 on the egg scraping component 13 from interfering with the egg-laying box 2.

[0052] like Figure 4 , Figures 6 to 11 As shown: Two guide frames 14 are provided between the two egg scraping components 13. The two guide frames 14 are mirror-symmetrical and located at both ends of the support frame 131. Both ends of the two guide frames 14 are provided with inclined guide grooves 141, and the guide grooves 141 of the two guide frames 14 are inclined towards the support frame 131. Both ends of the support frame 131 are provided with mounting boxes 1312 that are fixedly connected to the two guide frames 14. One of the mounting boxes 1312 is provided with a rotary drive motor 13121. The support frame 131 is provided with a drive shaft 1331 for driving the support arm 133 to rotate. The drive shaft 1331 is connected to the rotary drive motor 13121.

[0053] By using mounting box 1312, the two guide frames 14 and the two egg-scraping components 13 are combined to form an integrated structure, effectively improving the connection strength and stability of the equipment. Simultaneously, the rotary drive motor 13121 is housed within one of the mounting boxes 1312, which not only facilitates the protection of the motor and prevents it from being exposed on the outside of the equipment, but also effectively prevents black soldier fly eggs from falling onto the motor and affecting equipment operation, thus extending the equipment's service life.

[0054] After the rotary drive motor 13121 is started, the output shaft of the rotary drive motor 13121 drives the drive shaft 1331 connected to it. The rotation of the drive shaft 1331 can synchronously drive the rotation of the support arm 133, thereby driving the movement of the cleaning brush 132 located between the two support arms 133, so that the cleaning brush 132 scrapes the eggs on the side wall of the spawning box 2.

[0055] The scraped eggs slide down the top surface of the inclined support frame 131 and pass through two mirror-symmetrical guide frames 14. With the guide grooves 141 on the same side of the two guide frames 14 inclined towards the center of the support frame 131, the scraped eggs can slide into the collection box 11 in a concentrated manner, ensuring the effective collection and centralized management of the eggs, avoiding the loss and secondary pollution of the eggs, and improving the collection efficiency.

[0056] The combination of guide frame 14 and mounting box 1312 simplifies the functional distribution of the equipment, enabling the equipment to maintain a compact structure while optimizing its functions, and reducing manufacturing and maintenance costs.

[0057] like Figures 1 to 5As shown: The drive assembly 121 includes two swing arms 1211, which are mirror-symmetrical and can rotate relative to each other within the drive housing 12. Each swing arm 1211 is provided with a drive pin 12111 extending along the height direction. The top of the drive housing 12 is provided with an arc-shaped groove 231 that matches the drive pin 12111. The drive pin 12111 passes through the arc-shaped groove 231 to limit its movement trajectory. The top of the drive housing 12 is also provided with a positioning pin 122 extending along the vertical direction. The first spawning frame 21 is provided with a first mounting hole 212 that matches the positioning pin 122, and the second spawning frame 22 is provided with a second mounting hole 221 that matches the positioning pin 122.

[0058] The two swing arms 1211 of the drive assembly 121 are arranged in a mirror-symmetrical manner within the drive housing 12 and are capable of rotating relative to each other. A drive pin 12111 provided on each swing arm 1211 extends along the height direction and passes through an arc-shaped groove 231 on the top of the drive housing 12. The arc-shaped groove 231 restricts the movement trajectory of the drive pin 12111, making the movement of the swing arm 1211 more controllable.

[0059] First, the spawning box 2 is placed on the drive box 12. At this time, the first mounting hole 212 on the first spawning frame 21 is fitted onto the positioning pin 122, and the second mounting hole 221 on the second spawning frame 22 is fitted onto the drive pin 12111. When it is necessary to scrape off the black soldier fly eggs, the two swing arms 1211 are activated to rotate relative to each other. The rotation of the swing arms 1211 drives the drive pin 12111 to slide, allowing the drive pin 12111 to move along the arc-shaped slide groove 231, thereby driving the second spawning frame 22. The second ovipositor 22 is slidably mounted on the ovipositor box 2, and the first ovipositor 21 is fixed to the drive box 12 by the positioning pin 122. This allows the second ovipositor 22 to slide horizontally under the drive pin 12111, thereby causing the ovipositor plate 211 on the second ovipositor 22 to slide relative to the ovipositor plate 211 on the first ovipositor 21, until the black soldier fly eggs on the first ovipositor 21 and the second ovipositor 22 are scraped out. This further optimizes the egg collection process, reduces manual intervention, and improves production efficiency.

[0060] The drive pin 12111 is restricted by the arc-shaped slide groove 231 to ensure that the movement trajectory of the swing arm 1211 is fixed, thereby making the sliding movement between the second spawning frames 22 more precise and improving the reliability of equipment operation. The first spawning frame 21 is precisely fixed and positioned by the positioning pin 122 and the first mounting hole 212 of the first spawning frame 21, which improves the stability of equipment operation.

[0061] The combination structure of the positioning pin 122 and the first mounting hole 212 is simple, easy to assemble and disassemble, and at the same time reduces the potential risk of displacement during equipment operation and enhances operational safety.

[0062] like Figures 1 to 5 As shown: The drive assembly 121 also includes an electric actuator 1212 and two gears 1213. The electric actuator 1212 is located inside the drive housing 12, and one end of the electric actuator 1212 is hinged to the drive housing 12. The output shaft of the electric actuator 1212 is hinged to the end of one of the swing arms 1211. The two gears 1213 are rotatably disposed inside the drive housing 12. The two gears 1213 are meshed and located between the two swing arms 1211. Each of the two swing arms 1211 is provided with an incomplete gear disk 12112, and the incomplete gear disks 12112 of the two swing arms 1211 are respectively meshed with the gears 1213 on their sides.

[0063] The drive assembly 121 synchronously drives the swing arm 1211 through the linkage of the electric push rod 1212 and two gears 1213. When the electric actuator 1212 is activated, its output shaft extends or retracts, thereby driving one of the swing arms 1211 hinged to it to rotate. When the swing arm 1211 rotates, it drives the rotation of its incomplete gear disk 12112. Since both swing arms 1211 are equipped with incomplete gear disks 12112, and the incomplete gear disks 12112 are meshed with gears 1213 on the side of the swing arm 1211, the rotation of the incomplete gear disks 12112 drives the rotation of the gears 1213 meshing with them. The rotation of one gear 1213 drives the rotation of the other gear 1213 meshing with it, thereby driving the incomplete gear disk 12112 of the other swing arm 1211. This achieves synchronous drive of the two swing arms 1211.

[0064] The arrangement of the electric actuator 1212, gear 1213, and incomplete gear disc 12112 enables precise synchronization of the movement between the two swing arms 1211, ensuring uniform and reliable egg scraping operation. The incomplete gear disc 12112 limits the rotational range of the swing arms 1211, avoiding unnecessary extraneous movements and making the egg scraping process more focused and efficient. The cooperation between gear 1213 and the incomplete gear disc 12112 not only improves transmission stability but also reduces structural misalignment issues that might arise from the electric actuator 1212 directly applying force to a single swing arm 1211, enhancing the smoothness of equipment operation. Using the electric actuator 1212 as the drive source, precise control of the swing arms 1211 is achieved through the linear movement of the output shaft, avoiding the error accumulation problems that may occur with traditional drive motors, thereby further improving the accuracy of equipment operation. The use of gear 1213 transmission and incomplete gear disk 12112 structure reduces friction and wear between key components, extends the service life of drive assembly 121, and reduces maintenance frequency and cost. The electric actuator 1212 can be combined with a control system to achieve automated adjustment, improving the adaptability and intelligence of the equipment.

[0065] like Figures 6 to 9 As shown: The spawning box 2 has a first groove 23 at both ends inside, and the second spawning rack 22 has a slide rail 222 at both ends that matches the first groove 23.

[0066] By using slide rails 222 at both ends of the second spawning frame 22 to match the first slide groove 23 inside the spawning box 2, the second spawning frame 22 can be quickly and smoothly inserted or removed without complicated installation steps, greatly improving operational convenience. The cooperation between the first slide groove 23 and the slide rail 222 enables automatic alignment, ensuring that the second spawning frame 22 is in the correct working position after installation, avoiding reduced egg-scraping efficiency or equipment damage due to positional deviation. The interlocking structure of the first slide groove 23 and the slide rail 222 effectively limits the movement range of the second spawning frame 22, ensuring its stability during equipment operation and preventing displacement due to vibration or external forces. With the structure of the first slide groove 23 and the slide rail 222, the disassembly and cleaning of the second spawning frame 22 becomes easier, allowing for quick equipment maintenance and repair, improving equipment lifespan and overall operating efficiency.

[0067] like Figures 6 to 9 As shown: The first spawning frame 21 is provided with multiple first positioning plates 213. The multiple first positioning plates 213 are arranged at equal intervals along the height direction of the spawning box 2. Multiple spawning plates 211 are installed between the multiple first positioning plates 213. A first positioning post 214 is provided between the multiple first positioning plates 213. All the first positioning plates 213 are connected and fixed through the first positioning post 214.

[0068] Multiple first positioning plates 213 are connected by a first positioning post 214 to form a stable support structure, enhancing the overall compressive and seismic resistance of the first spawning frame 21 and effectively preventing component displacement or loosening during operation. The first positioning post 214 penetrates all the first positioning plates 213, ensuring the precise vertical distribution of each plate and providing accurate positioning for the spawning plate 211, further optimizing the spawning environment. This enables rapid installation and fixation of the spawning plate 211, simplifying the equipment assembly process and making maintenance or component replacement more convenient, thus improving operational efficiency.

[0069] The first positioning column 214 provides a unified support and fixing point for each first positioning plate 213, which disperses the force on each component, reduces stress concentration during the operation of the spawning frame, and improves the load-bearing capacity and service life of the first spawning frame 21.

[0070] The first positioning post 214 ensures the uniformity of the distance between the first positioning plate 213 and the oviposition plate 211, so that the internal space of the oviposition box 2 is reasonably divided, providing a consistent oviposition area for black soldier flies, avoiding crowding and improving oviposition efficiency.

[0071] like Figures 6 to 9 As shown: The second spawning frame 22 is provided with multiple second positioning plates 223. The multiple second positioning plates 223 are arranged at equal intervals along the height direction of the spawning box 2. Multiple spawning plates 211 are installed between the multiple second positioning plates 223. Second positioning posts 224 are provided between the multiple second positioning plates 223. All the second positioning plates 223 are connected and fixed by the second positioning posts 224.

[0072] Multiple second positioning plates 223 are connected by second positioning posts 224 to form an integrated support structure, which significantly improves the overall strength and seismic resistance of the second spawning frame 22, prevents components from loosening or shifting during operation, and facilitates the overall sliding of the second spawning frame 22. The second positioning plates 223 are evenly spaced along the height direction, providing uniform support and positioning for the spawning plates 211, ensuring a reasonable spatial distribution inside the spawning box 2, optimizing the spawning environment for black soldier flies, and improving spawning efficiency. The second positioning posts 224 provide uniform stress points among the multiple second positioning plates 223, dispersing load pressure, enhancing the load-bearing capacity of the spawning frame during use, and effectively extending the service life of the equipment.

[0073] like Figures 1 to 4 As shown: A support shaft 15 is provided on the frame 1, and the drive box 12 is rotatably mounted on the support shaft 15.

[0074] The drive box 12 can rotate flexibly through the support shaft 15, thereby driving the rotation of the spawning box 2. The rotation setting of the spawning box 2 makes it easy for staff to conduct a comprehensive inspection of the inside and outside of the spawning box 2 without disassembling the equipment, quickly identify and solve potential problems, reduce unnecessary losses in the breeding process, and enable staff to complete the operation without additional movement of the spawning box 2, effectively reducing labor intensity and improving the convenience and efficiency of operation.

[0075] By rotating the drive box 12, the spawning box 2 and related components can be more easily accessed, thus simplifying equipment maintenance and cleaning processes, extending equipment lifespan, and reducing maintenance costs. This meets various operational needs, such as adjusting the egg-scraping angle according to the black soldier fly egg production, and concentrating the collection of eggs from different directions, enhancing the equipment's functionality and flexibility.

[0076] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
