Description

Technical Field

[0001] The invention relates to the technical field of breeding equipment, and in particular to an automatic egg scraping machine for breeding black soldier flies. Background Art

[0002] The black soldier fly is a saprophytic insect of the family Solenopsis. It has been widely used in large-scale farming in recent years because it can efficiently convert organic waste and produce high-value animal protein feed. In the prior art, the common method of collecting black soldier fly eggs is to use a superimposed wooden board structure to form an egg-laying gap through wooden pads or thumbtacks. After the black soldier fly has finished laying eggs in the gap of the wooden board, it is necessary to manually remove the wooden boards one by one and use a scraper or brush to scrape off the eggs. Although this method has a simple structure, it is not easy to accurately adjust the gap height due to the size of the thumbtacks or wooden pads, which may lead to poor egg-laying effects in some areas; the efficiency of manual egg scraping is low, especially in large-scale farms, which requires a lot of manpower and affects production efficiency; the wooden boards need to be frequently replaced and cleaned, and the reusability is poor. Long-term use will lead to increased equipment maintenance costs.

[0003] In response to the above problems, a Chinese patent (authorization announcement number CN212728502U) discloses a rotary egg-laying and collecting device. The patent pivots a rotating egg-laying device on a frame and drives the egg-laying device to rotate by a hand crank. The bristles of the egg-scraping brush penetrate into the gaps between the egg-laying plates and scrape off the eggs as they rotate. The eggs eventually fall onto the mesh cover of the attractant box and are collected in a centralized manner. Compared with the traditional wooden board structure, this device realizes automated operation, and the egg-laying gap is fixed, ensuring the efficiency and reusability of egg collection. However, this device still has shortcomings in practical applications:

[0004] 1. The driving mode of the rotary ovipositor is single and mostly manual, which is inefficient and cannot meet the needs of large-scale farms for efficient automation;

[0005] 2. The scraped eggs cannot be effectively guided and are easily scattered or blocked inside the device, affecting the collection effect;

[0006] 3. The components are loosely connected, failing to form a stable integrated structure, and the reliability and maintainability of the equipment are poor. Summary of the invention

[0007] In view of the above problems, an automatic egg scraper for black soldier fly breeding is provided, by arranging an egg scraper assembly that can slide along the height direction of the egg-laying box on both sides of the drive box. The egg scraper assembly can further scrape the residual eggs on the edge of the egg-laying plate to ensure that all the eggs of black soldier flies in the egg-laying box can be completely detached, thereby realizing the efficient collection of black soldier fly eggs. The relative sliding movement between the egg-laying plates of the first egg-laying rack and the second egg-laying rack is realized by the drive assembly. Combined with the auxiliary role of the egg scraper assembly, the equipment can automatically complete the shedding and collection of black soldier fly eggs, greatly reducing manual participation and operation complexity, optimizing the production process and improving production efficiency.

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

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides egg scraping assemblies that can slide along the height direction of the egg-laying box on both sides of the drive box. These egg scraping assemblies can further scrape the residual eggs on the edge of the egg-laying plate to ensure that the eggs of black soldier flies in all egg-laying boxes can fall off completely, thereby realizing the efficient collection of black soldier fly eggs. The relative sliding movement between the egg-laying plates of the first egg-laying rack and the second egg-laying rack is realized by the drive assembly. Combined with the auxiliary role of the egg scraping assembly, the equipment can automatically complete the shedding and collection of black soldier fly eggs, greatly reducing manual participation and operation complexity, optimizing the production process and improving production efficiency. The relative movement between the egg-laying plates can efficiently scrape off most of the black soldier fly eggs, and the egg scraping assembly further removes the residual eggs on the edge of the egg-laying plate, ensuring the comprehensive collection of black soldier fly eggs and effectively reducing waste.

[0020] 2. The present invention can adapt to the side wall shape and pressure changes of the egg-laying box through the elastic telescopic structure of the support arm, and realizes efficient cleaning of egg residues in different positions. Through the synergistic effect of the cleaning brush and the support frame, the remaining black soldier fly eggs can be automatically collected on the support frame without complicated operations, and the subsequent recycling steps can be completed with simple tools, which greatly reduces the labor intensity. The two egg-scraping assemblies arranged in mirror symmetry can act on both sides of the egg-laying box at the same time, improving the egg-scraping efficiency. At the same time, the two egg-scraping assemblies can also play a limiting role for the egg-laying box, so that after the egg-laying box is placed on the drive box, the second egg-laying frame in the egg-laying box is driven by the drive assembly.

[0021] 3. The drive box can be flexibly rotated through the support shaft, thereby driving the rotation of the spawning box.

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figures 1 to 4 , Figures 6 to 9As shown: an automatic egg scraping machine for black soldier fly breeding, comprising a frame 1 and a recovery box 11 and an egg laying box 2 arranged on the frame 1, wherein the egg laying box 2 is provided with 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 arranged in the egg laying box 2; a plurality of egg laying plates 211 are arranged on the first egg laying frame 21 and the second egg laying frame 22, all the egg laying plates are arranged at intervals in the vertical direction, and there is a gap between two adjacent egg laying plates 211 for black soldier flies to lay eggs, and the egg laying plates 211 of the first egg laying frame 21 and the second egg laying frame 22 are arranged at intervals in the vertical direction, and the gap between the adjacent two egg laying plates 211 is provided for black soldier flies to lay eggs, and the egg laying plates 211 of the first egg laying frame 21 and the second egg laying frame 22 are arranged at intervals in the vertical direction, and the gap between the adjacent two egg laying plates 211 is provided for black soldier flies to lay eggs, and the egg laying plates 211 of the first egg laying frame 21 and the second egg laying frame 22 are arranged at intervals in the vertical direction, and the gap between the adjacent two egg laying plates 211 and ... 1 are arranged in a staggered manner; a driving box 12 is provided on the frame 1, and a driving assembly 121 is provided in the driving box 12 for driving the second spawning frame 22 to move, so that the spawning plate 211 on the second spawning frame 22 can move relative to the spawning plate 211 of the first spawning frame 21, thereby realizing the shedding and collection of black soldier fly eggs on the spawning plate 211; egg scraping assemblies 13 that can slide along the height direction of the spawning box 2 are provided on both sides of the spawning box 2 on the driving box 12, and the two egg scraping assemblies 13 are respectively used to scrape the end surfaces of the first spawning frame 21 and the second spawning frame 22 that are away from each other.

[0037] The spawning box 2 is placed in the breeding area before scraping the eggs. The black soldier flies will lay eggs on the spawning plates 211 of the first spawning rack 21 and the second spawning rack 22 under the action of the inducer. When the black soldier flies have finished laying eggs, the spawning box 2 is placed on the drive box 12, and the drive assembly 121 in the drive box 12 drives the second spawning rack 22 in the spawning box 2 to slide. Since the first spawning rack 21 is fixedly connected to the spawning box 2, during the sliding process of the second spawning rack 22, the spawning plates 211 of the second spawning rack 22 can produce relative movement relative to the spawning plates 211 of the first spawning rack 21.

[0038] By staggered arrangement and relative movement between the egg-laying plates 211 of the first egg-laying rack 21 and the second egg-laying rack 22, the eggs attached to the surface of the egg-laying plates 211 can be effectively scraped off until the eggs of the black soldier fly fall off from the ends of the first egg-laying rack 21 and the second egg-laying rack 22 that are away from each other, and the eggs of the black soldier fly fall into the recovery box 11, thereby completing the collection of the black soldier fly eggs.

[0039] Since the eggs of black soldier flies have strong viscosity, some of the eggs of black soldier flies are likely to remain on the end surface of the first spawning frame 21 and the second spawning frame 22 away from each other when scraped off during collection. To solve this problem, egg scraping assemblies 13 that can slide along the height direction of the spawning box 2 are provided on both sides of the driving box 12. These egg scraping assemblies 13 can further scrape off the residual eggs on the edge of the spawning plate 211, ensuring that the eggs of black soldier flies in all spawning boxes 2 can be completely detached, thereby realizing efficient collection of black soldier fly eggs.

[0040] The relative sliding movement between the egg-laying plates 211 of the first egg-laying rack 21 and the second egg-laying rack 22 is achieved by the driving component 121. Combined with the auxiliary function of the scraping egg component 13, the equipment can automatically complete the shedding and collection of black soldier fly eggs, greatly reducing manual participation and operation complexity, optimizing the production process and improving production efficiency. The relative movement between the egg-laying plates 211 can efficiently scrape off most of the black soldier fly eggs, and the scraping egg component 13 further removes the residual eggs on the edge of the egg-laying plates 211, ensuring the comprehensive collection of black soldier fly eggs and effectively reducing waste. The automated operation of the equipment not only reduces the manpower and time costs, but also provides higher economic benefits for breeding companies.

[0041] like Figure 4 , Figures 6 to 11 As shown: two egg scraping assemblies 13 are arranged on the driving box 12 in a mirror-symmetrical state, and a spacing matching the egg laying box 2 is left between the two egg scraping assemblies 13. The egg scraping assembly 13 includes a support frame 131, a cleaning brush 132 and two support arms 133. The support frame 131 is fixedly connected to the driving box 12, and 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, and the support arm 133 is an elastic telescopic structure.

[0042] The two support arms 133 are located on the support frame 131 in the initial state. When the support arms 133 rotate, the ends of the support arms 133 will abut against the side walls of the egg-laying box 2. Since the support arms 133 have the function of elastic expansion, during the rotation process, the support arms 133 can adapt to the contact pressure with the side walls of the egg-laying box 2 and slide along the height direction of the egg-laying 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 remaining on the side end surface of the egg-laying box 2 (i.e., the end surfaces of the egg-laying plates 211 of the first egg-laying frame 21 and the second egg-laying frame 22 that are away from each other) can be effectively removed. The eggs of the black soldier flies scraped off by the cleaning brush 132 will directly fall on the support frame 131, and the operator only needs to collect the eggs on the support frame 131 by means of a brush (in the prior art, the side walls of the egg-laying box 2 are generally scraped by the operator manually to assist in scraping eggs), thereby simplifying the subsequent processing steps.

[0043] The elastic telescopic structure of the support arm 133 can adapt to the shape of the side wall and the pressure change of the egg-laying box 2, and realize efficient cleaning of the egg residues at different positions. Through the synergistic effect 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, and the subsequent recovery steps can be completed with simple tools, which greatly reduces the labor intensity.

[0044] The mechanical movement of the egg scraping assembly 13 is automatically completed, reducing manual intervention, improving the automation level of the equipment, and contributing to the efficient management of large-scale breeding. Since the waste caused by egg residue is reduced, the egg recovery rate is increased, the economic benefits are improved, and the production cost is reduced.

[0045] The two egg scraping assemblies 13 arranged in a mirror-symmetrical manner can act on both sides of the egg laying box 2 at the same time, thereby improving the egg scraping efficiency. At the same time, the two egg scraping assemblies 13 can also play a limiting role for the egg laying box 2, so that after the egg laying box 2 is placed on the drive box 12, the second egg laying rack 22 in the egg laying box 2 can be driven by the drive assembly 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. The two pulleys 1321 are made of rubber material, and two limiting grooves 1311 matching with 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 gather in a designated area, reducing scattering and facilitating recycling in the recovery box 11 on the frame 1.

[0048] The rubber material of the pulley 1321 ensures that when the support arm 133 contacts and slides with the side wall of the egg-laying box 2, it can reduce friction and avoid direct contact between the support arm 133 and the egg-laying box 2, thereby causing damage to the surface of the egg-laying box 2. At the same time, the stability of the egg-scraping assembly 13 is enhanced during the sliding process, ensuring a smooth egg-scraping process.

[0049] Through the matching setting of the limit 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 inserted into the limit 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, avoiding the support arm 133 from loosening when not in use, and facilitating the storage and transportation of the equipment.

[0050] By rotating the support arm 133 again to release the pulley 1321 from the limiting groove 1311, the support arm 133 can slide along the side wall of the egg laying box 2 through the pulley 1321, driving the cleaning brush 132 to scrape the eggs, which is easy to operate, reduces manual intervention, and improves the automatic operation performance of the equipment.

[0051] At the same time, the setting of the limiting groove 1311 enables the two egg scraping components 13 to limit the egg laying box 2, which is convenient for it to be driven by the driving 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 arranged between the two egg scraping assemblies 13, and the two guide frames 14 are respectively located at the two ends of the support frame 131 in a mirror-symmetrical state. 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 toward one side of the support frame 131, and both ends of the support frame 131 are provided with installation boxes 1312 fixedly connected with the two guide frames 14, one of the installation boxes 1312 is provided with a rotating drive motor 13121, and the support frame 131 is provided with a driving shaft 1331 for driving the support arm 133 to rotate, and the driving shaft 1331 is transmission-connected to the rotating drive motor 13121.

[0053] By setting the installation box 1312, the two guide frames 14 are combined with the two egg scraping assemblies 13 to form an integral structure, which effectively improves the connection strength and stability of the device. At the same time, the rotary drive motor 13121 is set in one of the installation boxes 1312, which is not only convenient for protecting the motor and preventing it from being exposed to the outside of the device, but also effectively prevents the eggs of black soldier flies from falling on the motor to affect the operation of the device, thereby extending the service life of the device.

[0054] After the rotary drive motor 13121 is started, the output shaft of the rotary drive motor 13121 drives the drive shaft 1331 connected thereto. The rotation of the drive shaft 1331 can synchronously drive the rotation of the support arms 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 egg-laying box 2.

[0055] The scraped eggs will slide down through the top surface of the inclined support frame 131, through two guide frames 14 arranged in a mirror-symmetrical manner, through the setting of the guide groove 141, and the guide grooves 141 on the same side of the two guide frames 14 are inclined toward the center direction of the support frame 131, so that the scraped eggs can slide toward the recovery box 11 in a concentrated manner, ensuring the effective collection and centralized management of the eggs, avoiding the loss and secondary contamination of the eggs, and improving the collection efficiency.

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

[0057] like Figures 1 to 5As shown: the driving assembly 121 includes two swing arms 1211, and the two swing arms 1211 are located in the driving box 12 in a mirror-symmetrical state and can rotate relative to each other. The two swing arms 1211 are both provided with a driving pin 12111 extending in the height direction, and the top of the driving box 12 is provided with an arc-shaped slide groove 231 matching the driving pin 12111. The driving pin 12111 passes through the arc-shaped slide groove 231 to limit its movement trajectory. The top of the driving box 12 is also provided with a positioning pin 122 extending in the vertical direction, the first egg-laying frame 21 is provided with a first mounting hole 212 matching the positioning pin 122, and the second egg-laying frame 22 is provided with a second mounting hole 221 matching the positioning pin 122.

[0058] The two swing arms 1211 of the driving assembly 121 are arranged in a mirror-symmetrical form in the driving box 12 and can rotate relative to each other. The driving pin 12111 provided on each swing arm 1211 extends in the height direction and passes through the arc-shaped slide groove 231 at the top of the driving box 12. The arc-shaped slide groove 231 limits the movement trajectory of the driving pin 12111, making the movement of the swing arm 1211 more controllable.

[0059] First, place the egg-laying box 2 on the drive box 12. At this time, the first mounting hole 212 on the first egg-laying frame 21 is sleeved on the positioning pin 122, and the second mounting hole 221 on the second egg-laying frame 22 is sleeved on the driving pin 12111. When it is necessary to scrape the eggs of the black soldier fly, by starting the relative rotation of the two swing arms 1211, the rotation of the swing arms 1211 drives the sliding of the driving pin 12111, so that the driving pin 12111 can move along the arc-shaped slide groove 231, thereby driving the second egg-laying frame 22. Movement, since the second spawning rack 22 can be slidably arranged on the spawning box 2, and the first spawning rack 21 is fixed to the driving box 12 by the positioning pin 122, the second spawning rack 22 slides in the horizontal direction under the drive of the driving pin 12111, thereby driving the spawning plate 211 on the second spawning rack 22 to slide relative to the spawning plate 211 on the first spawning rack 21, until the eggs of the black soldier flies on the first spawning rack 21 and the second spawning rack 22 are scraped out, further optimizing the egg collection process, reducing manual intervention, and improving production efficiency.

[0060] The driving pin 12111 is limited by the arc-shaped slide groove 231 to ensure that the movement trajectory of the swing arm 1211 is fixed, so that the sliding movement between the second spawning frames 22 is more accurate, and the reliability of the equipment operation is improved. The first spawning frame 21 is accurately 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 the equipment operation.

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

[0062] like Figures 1 to 5 As shown: the driving component 121 also includes an electric push rod 1212 and two gears 1213, the electric push rod 1212 is located in the driving box 12, one end of the electric push rod 1212 is hinged to the driving box 12, the output shaft of the electric push rod 1212 is hinged to the end of one of the swing arms 1211, and the two gears 1213 are rotatably arranged in the driving box 12, the two gears 1213 are meshed and connected, and the two gears 1213 are located between the two swing arms 1211, and the two swing arms 1211 are both provided with incomplete toothed discs 12112, and the incomplete toothed discs 12112 of the two swing arms 1211 are respectively meshed and connected with the gears 1213 on their sides.

[0063] The driving assembly 121 realizes synchronous driving of the swing arm 1211 through the linkage of the electric push rod 1212 and the two gears 1213 . When the electric push rod 1212 is started, the output shaft of the electric push rod 1212 will extend or retract, thereby driving one of the swing arms 1211 hinged to it to rotate through the output shaft of the electric push rod 1212. When the swing arm 1211 rotates, it will drive the rotation of its incomplete toothed disc 12112. Since both swing arms 1211 are provided with incomplete toothed discs 12112, and the incomplete toothed discs 12112 are meshed with the gears 1213 on the side of the swing arm 1211, the rotation of the incomplete toothed disc 12112 drives the rotation of the gears 1213 meshed with it. The rotation of one of the gears 1213 drives the rotation of the other gear 1213 meshed with it, thereby driving the incomplete toothed disc 12112 of the other swing arm 1211, thereby realizing the synchronous driving of the two swing arms 1211.

[0064] Through the arrangement of the electric push rod 1212, the gear 1213 and the incomplete toothed disc 12112, the movement between the two swing arms 1211 can be precisely synchronized, thereby ensuring that the egg scraping operation is uniform and reliable. The arrangement of the incomplete toothed disc 12112 ensures that the rotational motion range of the swing arm 1211 is limited, avoids unnecessary redundant motion, and makes the egg scraping process more centralized and efficient. The cooperation of the gear 1213 and the incomplete toothed disc 12112 not only improves the stability of the transmission, but also reduces the structural deviation problem that may be caused by the direct force of the electric push rod 1212 on the single swing arm 1211, thereby enhancing the stability of the equipment operation. With the electric push rod 1212 as the driving source, the swing arm 1211 is precisely controlled by the linear motion of the output shaft, avoiding the error accumulation problem that may be caused by the traditional drive motor, thereby further improving the accuracy of the equipment operation. The use of gear 1213 transmission and incomplete toothed disc 12112 structure reduces friction and wear between key components, prolongs the service life of drive assembly 121, and reduces maintenance frequency and cost. Electric push rod 1212 can be combined with control system to realize automatic adjustment, improving the adaptability and intelligence of equipment.

[0065] like Figures 6 to 9 As shown, first slide grooves 23 are provided at both ends of the interior of the egg-laying box 2, and slide rails 222 matching the first slide grooves 23 are provided at both ends of the second egg-laying frame 22.

[0066] By matching the first chute 23 inside the spawning box 2 through the slide rails 222 at both ends of the second spawning rack 22, the second spawning rack 22 can be quickly and smoothly inserted or removed without complicated installation steps, which greatly improves the convenience of operation. The cooperation of the first chute 23 and the slide rail 222 can realize the automatic alignment function, ensuring that the second spawning rack 22 is in the correct working position after installation, avoiding the reduction of scraping efficiency or equipment damage due to position deviation. The interlocking structure of the first chute 23 and the slide rail 222 can effectively limit the movement range of the second spawning rack 22, ensuring that it remains stable during the operation of the equipment and will not be displaced due to vibration or external force. After adopting the structure of the first chute 23 and the slide rail 222, the disassembly and cleaning of the second spawning rack 22 becomes easier, and the equipment can be quickly maintained and maintained, which improves the service life and overall operation efficiency of the equipment.

[0067] like Figures 6 to 9 As shown: a plurality of first positioning plates 213 are arranged on the first egg-laying frame 21, and the plurality of first positioning plates 213 are arranged equidistantly along the height direction of the egg-laying box 2, and a plurality of egg-laying plates 211 are installed between the plurality of first positioning plates 213, and a first positioning column 214 is arranged between the plurality of first positioning plates 213, and all the first positioning plates 213 are connected and fixed by the first positioning columns 214.

[0068] The first positioning column 214 connects multiple first positioning plates 213 to form a stable support structure, which enhances the overall pressure resistance and shock resistance of the first spawning frame 21, and effectively prevents the displacement or loosening of components during operation. The first positioning column 214 runs through all the first positioning plates 213, ensuring the precise distribution position of each first positioning plate 213 in the height direction, providing accurate positioning for the spawning plate 211, and further optimizing the spawning environment. In this way, the spawning plate 211 can be quickly installed and fixed, simplifying the assembly process of the equipment, and it is also more convenient when maintenance or replacement of components is required, thereby improving the operating efficiency.

[0069] The first positioning columns 214 provide a unified support and fixing point for each first positioning plate 213 , disperse the forces on each component, reduce stress concentration during operation of the spawning frame, and improve the bearing capacity and service life of the first spawning frame 21 .

[0070] The first positioning column 214 ensures that the spacing between the first positioning plate 213 and the egg-laying plate 211 is uniform, so that the internal space of the egg-laying box 2 is reasonably divided, providing a consistent egg-laying area for the black soldier flies, avoiding crowding, and improving the egg-laying efficiency.

[0071] like Figures 6 to 9 As shown: a plurality of second positioning plates 223 are arranged on the second egg-laying frame 22, and the plurality of second positioning plates 223 are arranged equidistantly along the height direction of the egg-laying box 2, a plurality of egg-laying plates 211 are installed between the plurality of second positioning plates 223, and second positioning columns 224 are arranged between the plurality of second positioning plates 223, and all the second positioning plates 223 are connected and fixed by the second positioning columns 224.

[0072] The second positioning column 224 penetrates and connects multiple second positioning plates 223 to form an integrated support structure, which significantly improves the overall strength and anti-seismic ability of the second spawning frame 22, avoids loosening or displacement of components during operation, and facilitates the overall sliding of the second spawning frame 22. The second positioning plates 223 are arranged equidistantly in 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 of black soldier flies, and improving the spawning efficiency. The second positioning column 224 provides uniform force points between multiple second positioning plates 223, disperses the load pressure, enhances the bearing capacity of the spawning frame during use, and effectively extends the service life of the equipment.

[0073] like Figures 1 to 4 As shown: a support shaft 15 is arranged on the frame 1, and the driving box 12 is rotatably arranged on the support shaft 15.

[0074] The driving box 12 can be flexibly rotated through the supporting shaft 15, thereby driving the rotation of the egg-laying box 2. The rotating setting of the egg-laying box 2 is convenient for the staff to conduct a comprehensive inspection of the inside and outside of the egg-laying box 2 without disassembling the equipment, quickly discover and solve potential problems, reduce unnecessary losses in the breeding process, and enable the staff to complete the operation without additionally moving the egg-laying box 2, effectively reducing labor intensity and improving the convenience and efficiency of operation.

[0075] By rotating the drive box 12, the egg-laying box 2 and related components can be more easily accessed, thereby simplifying the equipment maintenance and cleaning process, extending the service life of the equipment, and reducing maintenance costs. Different operational requirements are met, such as adjusting the egg scraping angle according to the output of black soldier fly eggs, and centrally collecting eggs in different directions, thereby enhancing the functionality and flexibility of the equipment.

[0076] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
