Description

Technical Field

[0001] This invention relates to the field of black soldier fly breeding technology, and more specifically, to a device for black soldier fly egg laying and hatching. Background Technology

[0002] Black soldier flies are insects belonging to the genus *Bufo* in the family Bandidae of the order Diptera. Their life cycle includes egg, larva, prepupa, pupa, and adult stages. Black soldier flies are renowned for their ability to convert organic waste into valuable biomass. Their high protein content and other nutrients make them an excellent source of nutrition for animals, especially poultry and fish. Furthermore, black soldier fly larvae can effectively process organic waste, reducing environmental pollution. Currently, oviposition and hatching occur in separate containers, leading to resource waste and increased breeding costs. Moreover, the collection and transfer of eggs after oviposition often results in egg accumulation, which, if not addressed promptly, affects egg survival rates during hatching. Additionally, environmental factors make it difficult for black soldier flies to maintain high growth rates and productivity. Therefore, it is necessary to provide a device for black soldier fly oviposition and hatching to address the problems mentioned in the background section. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a device for black soldier fly spawning and hatching, comprising:

[0004] The container is constructed from durable, food-grade safe materials and features multiple compartments with openings around the top.

[0005] The inducer placement box is installed at the bottom of the box;

[0006] A 60-mesh mesh is installed in the middle of the box, above the guide placement box;

[0007] The egg-laying collection device is located on the upper part of the box, parallel to the mesh screen;

[0008] The rotating mechanism, located on the top of the box, is connected to the egg-laying and collection device and is driven by an external motor;

[0009] The feed trough and the attractant placement box are located in the same position, and the two can be switched.

[0010] Furthermore, as a preferred embodiment, the enclosure is divided into three compartments from top to bottom, corresponding to the three stages of black soldier fly egg-laying, hatching, and larval development. The egg-laying compartment is equipped with a lighting device, while the larval development compartment is equipped with temperature and humidity sensors, as well as heating and humidification devices. That is, when the temperature and humidity sensors detect that the temperature and humidity inside the enclosure are lower than set values, the heating and humidification devices are controlled to heat and humidify the microenvironment inside the enclosure, while the lighting device provides adequate light for the black soldier flies laying eggs, thus achieving the most suitable egg-laying and hatching conditions for them.

[0011] Furthermore, preferably, the spawn collection device includes:

[0012] The connecting frame is installed inside the egg-laying compartment of the box;

[0013] Multiple egg-laying collection components are coaxially arranged, with the outer egg-laying collection components fixedly connected to the connecting frame.

[0014] An adjusting ring is connected to an adjacent egg-laying collection assembly, and its top is connected to a rotating mechanism;

[0015] The central circular surface and sides are connected to the internal egg-laying collection components, while the top is connected to the rotating mechanism. Multiple egg-laying collection components, positioned on the same horizontal plane, are arranged inside the box under the action of the connecting frame and adjusting ring. During the egg-laying stage, black soldier flies, attracted by the odor inside the attractant placement box at the bottom of the box, enter through the opening at the top of the box and lay eggs in the gaps between the egg-laying collection components. After each batch of eggs is laid, the rotating mechanism, via the central circular surface, causes the egg-laying collection components to shift sequentially. The adjusting ring then causes the egg-laying collection components to rotate relative to each other, scraping off the eggs. The eggs fall onto the mesh screen, and the attractant placement box at the bottom is replaced with a feeding trough. This adjusts the internal environment of the box, allowing the eggs to hatch. The hatched larvae fall through the mesh screen into the feeding trough for feeding.

[0016] Furthermore, preferably, the spawn collection assembly includes:

[0017] The outer spawning ring, located on the outer spawning collection component, is fixedly connected to the connecting frame, while the other outer spawning rings are connected to the inner wall of the adjustment ring.

[0018] The inner ring egg scraping component is fixed to the top of the outer ring surface where eggs are laid;

[0019] The inner spawning ring is fixedly connected to the outer side of the central circular surface on the inner spawning collection component. The other inner spawning rings are connected to the outer wall of the adjustment ring, and the inner spawning rings and outer spawning rings are spaced apart.

[0020] The outer ring egg scraping component is fixed at the bottom of the inner ring surface of the egg-laying area, and a second egg scraping plate is provided on the outer side in a ring. In other words, during the oviposition stage, the outer and inner oviposition rings correspond to each other and have gaps between them. Based on the black soldier fly's habit of choosing relatively dry crevices nearby for oviposition, the black soldier flies, attracted by the scent of the attractant placed in the box at the bottom of the enclosure, lay their eggs in the gaps between the outer and inner oviposition rings. After oviposition, a rotating mechanism, through the central circular surface and adjusting ring, sequentially causes the oviposition collection components to shift out of position. This causes the inner oviposition ring to move upwards, corresponding to the inner ring egg-scraping component, and simultaneously causes the outer ring egg-scraping component to move upwards, corresponding to the outer oviposition ring. Driven by the rotating mechanism, the two sides of the oviposition collection components rotate relative to each other, scraping off the eggs with the scraping plates. The eggs fall through the gaps onto the mesh. Because the eggs are laid in multiple annular gaps, they are evenly distributed on the mesh after falling, effectively increasing the hatching rate during incubation.

[0021] Furthermore, preferably, the outer ring of the spawning surface includes:

[0022] Multiple limiting arc surfaces are arranged in a ring and fixed on the upper side wall of the outer ring surface of the egg-laying surface. The length of the limiting arc surface is greater than the distance between adjacent second egg-scraping plates, and the width is less than the distance between the outer ring surface of the egg-laying surface and the inner ring surface of the egg-laying surface. It only contacts the top of the second egg-scraping plate.

[0023] The connecting arc surface is fixed on the lower side wall of the outer ring surface of the egg-laying surface, corresponding to the limiting arc surface;

[0024] The limiting shaft is fixed to the lower part of the connecting arc surface, and is supported by the outer ring egg-scraping assembly. That is, when the inner ring surface of the egg-laying structure moves the outer ring egg-scraping assembly upward, the second egg-scraping plate moves upward against the outer ring surface of the egg-laying structure until it contacts the limiting arc surface. Then, under the action of the central circular surface, multiple egg-laying collection components are sequentially misaligned, starting from the middle egg-laying collection component. Similarly, after the eggs are scraped off, the rotating mechanism moves the inner ring surface of the egg-laying structure and the outer ring egg-scraping assembly downward and resets them. Then, the bottom of the outer ring egg-scraping assembly contacts the limiting shaft, and the outer ring egg-scraping assembly stops moving. Then, multiple outer ring egg-scraping components and the inner ring surface of the egg-laying structure are sequentially reset.

[0025] Furthermore, preferably, the inner ring egg scraping assembly includes:

[0026] A fixing ring is fixed to the top of the outer ring surface of the spawning area, and has multiple pop-out components arranged in a ring inside;

[0027] The guide arc surface is located on the inner side of the fixing ring;

[0028] Multiple first-stage egg-scraping plates, arranged in a ring, are connected to a pop-up assembly. When the black soldier fly lays eggs, the first egg-scraping plates retract into a fixed ring under the action of the pop-up assembly. During egg collection, before the inner ring surface of the egg-laying area moves the outer ring egg-scraping assembly upwards, the pop-up assembly ejects the first egg-scraping plates, bringing them into contact with the inner ring surface. The inner ring surface then moves upwards along the first egg-scraping plate until they are completely in contact. During the rotating scraping process, the eggs on the inner ring surface fall off, guided by an arc surface, and then fall between the outer ring surface and the outer ring egg-scraping assembly onto the mesh. The guiding arc surface effectively prevents excessive eggs from falling in a straight line, thus preventing blockage of the gaps and damage to the eggs.

[0029] Furthermore, preferably, the rotating mechanism includes:

[0030] The central gear is located at the top center of the housing, corresponding to the central circular surface, and is connected to the external motor;

[0031] Double-sided gear rings are coaxially arranged with the central gear and correspond to the adjusting ring below;

[0032] The gear ring is coaxially arranged with the central gear and corresponds to the outermost adjusting ring;

[0033] A fixed gear is positioned between the central gear and the double-sided gear rings, and between the double-sided gear rings and the gear ring;

[0034] Rotate the telescopic shaft to connect the central gear and the central circular surface;

[0035] The passive telescopic shaft connects the double-sided toothed rings and toothed rings to their corresponding adjusting rings. In other words, under the action of an external motor, the central gear rotates, driving the double-sided toothed rings and toothed rings to rotate via a fixed gear. This, in turn, causes the central circular surface and adjusting rings to rotate relative to each other, scraping off the eggs. When the telescopic shaft retracts, it causes the central circular surface to move upwards, which in turn causes the inner egg-laying ring surface in the central egg-laying collection assembly to move upwards. When the outer ring egg-scraping assembly below the inner egg-laying ring surface is restricted by the limiting arc surface, the adjacent egg-laying collection assembly is misaligned under the action of the adjusting ring, simultaneously causing the passive telescopic shaft to retract. When the telescopic shaft extends, the egg-laying collection assembly resets. Under the restriction of the limiting shaft, the egg-laying collection assemblies reset sequentially, simultaneously causing the passive telescopic shaft to extend and reset, thus achieving unified control of multiple egg-laying collection assemblies.

[0036] Furthermore, as a preferred embodiment, a pressure ring is rotatably provided on the side wall of the rotating telescopic shaft to control the extended end of the rotating telescopic shaft. Under the action of the pressure ring, the rotating telescopic shaft can be adjusted for extension and retraction while still being rotatable; of course, rotation and extension should be performed separately.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] In this invention, multiple coaxially arranged egg-laying collection components scrape off the eggs after the black soldier fly has finished laying them and distribute them evenly on a mesh screen for incubation, effectively improving the hatching rate of the eggs. Under the action of multiple environmental control modules, temperature, humidity and light are systematically controlled, effectively improving the year-round production of black soldier flies and minimizing seasonal changes in supply.

Detailed Implementation

[0046] Please see Figures 1-6 In this embodiment of the invention, a device for black soldier fly spawning and hatching includes:

[0047] Box 1 is constructed from durable, food-grade safe materials and has multiple compartments with openings around the top.

[0048] The inducer placement box 2 is installed at the bottom of the box body 1;

[0049] The mesh 3, which is 60 mesh, is installed in the middle of the box 1, above the guide placement box 2;

[0050] The egg-laying collection device 4 is set on the upper part of the box 1, parallel to the mesh 3;

[0051] The rotating mechanism 5 is located on the top of the box 1 and is connected to the egg-laying collection device 4. It is driven by an external motor.

[0052] Feed trough 6 and inducer placement box 2 are located in the same position and can be switched between each other.

[0053] In this embodiment, the box 1 is divided into three compartments from top to bottom, corresponding to the three stages of black soldier fly egg laying, hatching, and larval development. The egg laying compartment is equipped with a lighting device, while the larval development compartment is equipped with temperature and humidity sensors, as well as heating and humidification devices. That is, when the temperature and humidity sensors detect that the temperature and humidity inside the box 1 are lower than set values, the heating and humidification devices are controlled to heat and humidify the microenvironment inside the box 1. Simultaneously, the lighting device provides adequate light for the black soldier flies laying eggs, achieving the most suitable egg laying and hatching conditions for them.

[0054] In this embodiment, the spawn collection device 4 includes:

[0055] The connecting frame 41 is set inside the egg-laying compartment of the box 1;

[0056] Multiple egg-laying collection components 42 are coaxially arranged, with the outer egg-laying collection component 42 fixedly connected to the connecting frame 41.

[0057] The adjusting ring 43 is connected to the adjacent egg-laying collection assembly 42, and its top is connected to the rotating mechanism 5;

[0058] The central circular surface 44 is connected to the internal egg-laying collection components 42 on the side and to the rotating mechanism 5 on the top. Under the action of the connecting frame 41 and the adjusting ring 43, multiple egg-laying collection components 42 on the same horizontal plane are set inside the box 1. During the egg-laying stage, black soldier flies are attracted by the odor inside the attractant placement box 2 at the bottom of the box 1 and enter the gaps of the egg-laying collection components 42 through the opening at the top of the box 1 to lay eggs. After the same batch of eggs is laid, the rotating mechanism 5 drives the egg-laying collection components 42 to be staggered in sequence through the central circular surface 44, and then drives the egg-laying collection components 42 to rotate relative to each other through the adjusting ring 43, scraping off the eggs. The eggs fall onto the mesh 3, and then the attractant placement box 2 at the bottom is replaced with a feed trough 6, thereby adjusting the internal environment of the box 1 to hatch the eggs. The hatched larvae fall into the feed trough 6 through the mesh 3 for feeding.

[0059] In this embodiment, the egg-laying collection component 42 includes:

[0060] The outer ring surface 421 of the egg-laying device is fixedly connected to the connecting frame 41, and the other outer ring surfaces 421 of the egg-laying device are connected to the inner wall of the adjusting ring 43.

[0061] The inner ring egg scraping component 422 is fixed to the top of the outer ring surface 421 where eggs are laid;

[0062] The inner oviposition ring 423, located on the inner oviposition collection component 42, is fixedly connected to the outer side of the central circular surface 44. The other inner oviposition rings 423 are connected to the outer wall of the adjustment ring 43, and the inner oviposition rings 423 and the outer oviposition rings 421 are spaced apart.

[0063] The outer ring egg-scraping component 424 is fixed to the bottom of the inner egg-laying ring surface 423, and a second egg-scraping plate 4241 is provided on the outer side in a ring. That is to say, during the egg-laying stage, the outer egg-laying ring surface 421 and the inner egg-laying ring surface 423 correspond to each other and there is a gap between them. According to the black soldier fly's habit of choosing nearby relatively dry crevices to lay eggs, the black soldier fly attracted by the scent in the attractant placement box 2 at the bottom of the box 1 lays its eggs in the gap between the outer egg-laying ring surface 421 and the inner egg-laying ring surface 423. Then, after the egg-laying is completed, the rotating mechanism 5 drives the egg-laying collection component 42 to move in turn through the central circular surface 44 and the adjusting ring 43. The misalignment causes the inner ring surface 423 of the egg-laying assembly to move upward, corresponding to the inner ring egg-scraping component 422. At the same time, it drives the outer ring egg-scraping component 424 to move upward, corresponding to the outer ring surface 421 of the egg-laying assembly. Then, driven by the rotating mechanism 5, the two sides of the egg-laying collection component 42 rotate relative to each other, scraping off the eggs through the egg-scraping plate. The eggs fall onto the mesh 3 through the gaps. Since the eggs are laid in multiple annular gaps, they are distributed relatively evenly on the mesh 3 after falling, which effectively improves the hatching rate of the eggs during incubation.

[0064] In this embodiment, the outer annular surface 421 for spawning includes:

[0065] Multiple limiting arc surfaces 4211 are arranged in a ring and fixed on the upper side wall of the outer ring surface 421 of the egg-laying surface. The length of the limiting arc surface 4211 is greater than the distance between adjacent second egg-scraping plates 4241, and the width is less than the distance between the outer ring surface 421 of the egg-laying surface and the inner ring surface 423 of the egg-laying surface. It only contacts the top of the second egg-scraping plate 4241.

[0066] The connecting arc surface 4212 is fixed on the lower side wall of the outer ring surface 421 of the egg-laying surface, corresponding to the limiting arc surface 4211;

[0067] The limiting shaft 4213 is fixed to the lower part of the connecting arc surface 4212, and is supported by the outer ring egg scraping component 424. That is, when the inner ring surface 423 moves the outer ring egg scraping component 424 upward, the second egg scraping plate 4241 moves upward against the outer ring surface 421 until it contacts the limiting arc surface 4211. Then, under the drive of the central circular surface 44, multiple egg collection components 42 are sequentially misaligned starting from the middle egg collection component 42. Similarly, after the eggs are scraped off, the rotating mechanism 5 moves the inner ring surface 423 and the outer ring egg scraping component 424 downward to reset. Then, the bottom of the outer ring egg scraping component 424 contacts the limiting shaft 4213, and the outer ring egg scraping component 424 stops moving. Then, multiple outer ring egg scraping components 424 and the inner ring surface 423 are sequentially reset.

[0068] In this embodiment, the inner ring egg scraping assembly 422 includes:

[0069] The fixing ring 4221 is fixed to the top of the outer ring surface 421 of the egg-laying ring, and has multiple pop-out components arranged in a ring inside;

[0070] The guide arc surface 4222 is located on the inner side of the fixing ring 4221;

[0071] Multiple first egg-scraping plates 4223 are arranged in a ring and connected to the ejector assembly. When the black soldier fly lays eggs, the first egg-scraping plates 4223 retract into the fixed ring 4221 under the action of the ejector assembly. When collecting eggs, before the inner ring surface 423 moves the outer ring egg-scraping assembly 424 upward, the ejector assembly ejects the first egg-scraping plates 4223, making them fit against the inner ring surface 423. The inner ring surface 423 then moves upward along with the first egg-scraping plates 4223 until the first egg-scraping plates 4223 are completely in contact with the inner ring surface 423. Then, during the rotation and scraping, the eggs on the inner ring surface 423 fall off, pass through the guide arc surface 4222, and then fall between the outer ring surface 421 and the outer ring egg-scraping assembly 424 onto the mesh 3. Under the action of the guide arc surface 4222, it effectively prevents the eggs from falling in a straight line and clogging the gaps, thus preventing damage to the eggs.

[0072] In this embodiment, the rotating mechanism 5 includes:

[0073] The central gear 51 is located at the top center of the housing 1, corresponding to the central circular surface 44, and is connected to an external motor;

[0074] The double-sided toothed ring 52 is coaxially arranged with the central gear 51 and corresponds to the adjusting ring 43 below;

[0075] The gear ring 53 is coaxially arranged with the central gear 51 and corresponds to the outermost adjusting ring 43;

[0076] A fixed gear 54 is disposed between the central gear 51 and the double-sided gear ring 52, and between the double-sided gear ring 52 and the gear ring 53;

[0077] Rotate the telescopic shaft 55 to connect the central gear 51 and the central circular surface 44;

[0078] The passive telescopic shaft 56 connects the double-sided toothed rings 52 and 53 to the corresponding adjusting rings 43. In other words, under the action of an external motor, the central gear 51 rotates, which drives the double-sided gear rings 52 and gear rings 53 to rotate through the fixed gear 54. Then, under the drive of the rotating telescopic shaft 55 and the passive telescopic shaft 56, the central circular surface 44 and the adjusting ring 43 rotate relative to each other, scraping off the eggs. When the rotating telescopic shaft 55 retracts, it drives the central circular surface 44 to move upward, which in turn drives the inner egg-laying ring surface 423 in the middle egg-laying collection component 42 to move upward. When the outer ring egg-scraping component 424 below the inner egg-laying ring surface 423 is restricted by the limiting arc surface 4211, the adjacent egg-laying collection component 42 is misaligned under the action of the adjusting ring 43, and at the same time, it drives the passive telescopic shaft 56 to retract. When the rotating telescopic shaft 55 extends, the egg-laying collection component 42 resets. Under the restriction of the limiting shaft 4213, the egg-laying collection component 42 resets in sequence, and at the same time, it drives the passive telescopic shaft 56 to extend and reset, so as to complete the unified control of multiple egg-laying collection components 42.

[0079] In this embodiment, a pressure ring is rotatably provided on the side wall of the rotating telescopic shaft 55 to control the extended end of the rotating telescopic shaft 55. Under the action of the pressure ring, the rotating telescopic shaft 55 can be adjusted for extension and retraction while still being rotatable. Of course, rotation and extension should be performed separately.

[0080] In practice, the attractant placement box 2 is first placed at the bottom of the box 1, and then the box 1 is closed. The internal environment of the box 1 is regulated by lighting, heating, and humidification equipment to maintain a suitable environment for egg laying. Then, under the attraction of the scent in the attractant placement box 2, the black soldier flies enter the egg-laying collection device 4 through the opening at the top of the box 1. They then lay eggs in the gaps between the egg-laying collection components 42. When a sufficient number of eggs are laid, the bottom attractant placement box 2 is replaced with a feed trough 6, and the opening on the box 1 is closed. Then, the ejector component ejects the first egg-scraping plate 4223, making it fit against the inner annular surface 423 of the egg-laying device. Then, the telescopic shaft 55 is rotated and contracted under the action of the pressure ring, and the eggs are sequentially pulled out through the central circular surface 44 and the adjusting ring 43. The inner ring surface 423 and the outer ring egg-scraping component 424 are moved upward and misaligned, so that the first egg-scraping plate 4223 is in contact with the inner ring surface 423 and the second egg-scraping plate 4241 is in contact with the outer ring surface 421. Then, the rotating mechanism 5 is driven by an external motor to rotate. Under the drive of the rotating telescopic shaft 55 and the passive telescopic shaft 56, the central circular surface 44 and the adjusting ring 43 rotate relative to each other. The egg-scraping plate scrapes the eggs off, and the eggs fall onto the mesh 3. Then, the pop-out part retracts the first egg-scraping plate 4223, and then the rotating telescopic shaft 55 extends, driving the egg-laying collection component 42 to reset. Then, the controller adjusts the heating and humidification equipment to make the internal environment of the box 1 meet the hatching conditions. Then, the hatched larvae fall into the feed trough 6 through the mesh 3 for feeding.

[0081] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
