Description

Technical Field

[0001] This utility model relates to a device for collecting and hatching black soldier fly eggs, belonging to the field of black soldier fly farming. Background Technology

[0002] Black soldier flies, belonging to the genus *Bufo* of the family Typhonidae in the order Diptera, are saprophytic insects. They possess antithrombin, anti-inflammatory, and analgesic properties, and are particularly rich in antibacterial substances, giving them significant medicinal and health-related development value. Animals fed with black soldier flies can benefit from improved physical condition, enhanced immunity, and reduced disease. Black soldier flies can also replace fishmeal as feed. Their excrement serves as a highly efficient organic fertilizer for the production of organic agricultural products.

[0003] A bottleneck exists in large-scale black soldier fly farming: low efficiency in egg collection and hatching. To address this, the industry primarily employs two egg collection methods: one is the stacking of wooden or bamboo boards, using the gaps to induce egg laying followed by manual scraping. However, this method easily causes mechanical damage, adhesion, and contamination of the eggs, and makes accurate egg counting difficult, hindering standardized production. The other method is using corrugated cardboard for egg collection. While this avoids the scraping step, the eggs may clog the ends of the holes, leading to oxygen deprivation and death of the internal eggs. Furthermore, the hatched larvae struggle to escape, further reducing the hatching rate. Existing hatching equipment generally lacks precise temperature and humidity control and hygiene management, resulting in an unstable hatching environment and significant problems with dead eggs and mold growth. Meanwhile, small-scale farmers face difficulties in egg collection due to the complexity and high cost of their equipment, limiting the industry's promotion and development.

[0004] Therefore, this utility model provides a solution that optimizes egg collection and hatching technology, develops an efficient, low-cost and easy-to-operate solution, and improves the hatching rate of insect eggs and promotes the large-scale application of black soldier fly farming. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a device for collecting and hatching black soldier fly eggs to solve the problems of low hatching rate of black soldier fly eggs and difficulty in collecting eggs for small-scale farmers.

[0006] This utility model is implemented as follows:

[0007] A device for collecting and hatching black soldier fly eggs includes a first mesh, a corrugated plate, a second mesh, and a hatching layer arranged sequentially from top to bottom, wherein the hatching layer is a polygonal structure that runs vertically through the structure.

The space between the inside of the incubation layer and the second mesh is the incubation chamber, and the egg collection chamber is a number of cavities formed by the superposition of a corrugated plate and the first mesh or the second mesh.

[0009] The egg collection chamber is used to collect black soldier fly eggs, and the hatching chamber is used to place materials and hatch black soldier fly eggs.

[0010] As a further improvement, the incubation layer also includes a material gate, which is located on one side of the incubation layer. The horizontal side of the material gate is hinged to the incubation layer, and the other horizontal end of the material gate is detachably and fixedly connected to the incubation layer by a latch, so as to open or close the material gate.

[0011] As a further improvement, the incubation layer is detachably and fixedly equipped with a temperature sensor and a humidity sensor, which are used to test the temperature and humidity inside the incubation layer, respectively.

[0012] As a further improvement, the present invention also includes two or more glass plates, which are located above the first mesh or at the bottom of the incubation layer.

[0013] As a further improvement, this utility model also includes several screws and fixing holes. Fixing holes are opened on the side plate at each corner of the incubation layer, and second fixing holes are also opened on the first mesh and the second mesh corresponding to the fixing holes.

[0014] The screw passes through the first mesh, the second mesh, the incubation layer, and the glass plate in sequence, and is fixed at both ends with nuts, so as to realize the series fixation of the first mesh, the wave plate, the second mesh, the incubation layer, and the glass plate.

[0015] As a further improvement, the density of the first and second meshes is 200 mesh or more.

[0016] As a further improvement, the wave plate is composed of a curved plate and vertical parts fixed at both ends of the curved plate, and the ends of the vertical parts are provided with a second fixing hole that runs vertically through the plate.

[0019] As a further improvement, the lower end of the inner wall of the incubation layer is provided with an extension, which is used to support the wave plate in the incubation state.

[0020] The beneficial effects of this utility model are:

[0021] ① This utility model combines the functions of collecting and hatching black soldier fly eggs. The adjacent egg collection chambers are effectively isolated by the corrugated plate itself, preventing them from sticking together and reducing the number of black soldier fly eggs piled up. The number of black soldier fly eggs in the egg collection chamber per unit space is small, reducing oxygen consumption in the local space. Furthermore, the design of the first and second mesh screens widens the air circulation channels, increasing the oxygen content in the unit space and eliminating the problem of local hypoxia, thereby improving the survival rate of the eggs.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Example

[0034] Reference Figures 1 to 6 As shown, this embodiment provides a specific implementation of a device for collecting and hatching black soldier fly eggs, including a first mesh 10, a corrugated plate 20, a second mesh 30 and an incubation layer 40 arranged sequentially from top to bottom. The incubation layer 40 is a polygonal structure with an open top, including but not limited to a cuboid with an open top, so that the interior of the incubation layer 40 can contain materials. The materials mentioned here include, but are not limited to, putrid substances, such as rotten kitchen waste, etc.

[0035] This utility model also includes an incubation chamber 50 and an egg collection chamber 60. The space between the inside of the incubation layer 40 and the second mesh 30 is the incubation chamber 50. The egg collection chamber 60 is a number of cavities formed by the corrugated plate 20 and the first mesh 10 or the second mesh 30 superimposed.

[0036] The egg collection chamber 60 is used to collect black soldier fly eggs, and the hatching chamber 50 is used to place materials and hatch black soldier fly eggs.

[0037] In the above technical solution, during the egg-collecting state, materials such as rotten kitchen waste are placed on the first mesh 10 in the hatching layer 40 to attract black soldier fly larvae to lay eggs in the egg-collecting chamber 60. The black soldier fly eggs are supported by the corrugated plate 20 and the second mesh 30. The adjacent egg-collecting chambers 60 are effectively isolated by the corrugated plate 20 itself to prevent them from sticking together and reduce the number of black soldier fly eggs piled up. The number of black soldier fly eggs in the egg-collecting chamber 60 per unit space is small, and the oxygen consumption in the local space is reduced. Furthermore, the design of the first mesh 10 and the second mesh 30 widens the air circulation channel and increases the oxygen content in the unit space, eliminating the problem of local hypoxia and thus improving the survival rate of the eggs.

[0038] During the incubation period, the second mesh 20 is moved down onto the first mesh 10 of the next layer, and the corrugated plate 20 is also reversed and placed in the incubation layer 40. Most of the insect eggs on the corrugated plate 20 enter the incubation chamber under the action of gravity and hatch directly without being damaged by artificial brushes, which significantly improves the hatching rate. The material in the incubation chamber 50 is also replaced with incubation auxiliary materials, including but not limited to wheat bran.

[0039] In practice, the material in the incubation chamber 50 can be laid with a thickness of 0.5cm.

[0040] In this embodiment, the horizontal width of the incubation layer 40 is greater than the horizontal width of the wave plate 20. The second mesh 30 completely or partially covers the top surface of the incubation layer 40, so that when the wave plate 20 is mounted on the second mesh 30, there is space on both sides of the top surface of the incubation layer 40, so that there is a circulation channel between the incubation layer 40 and the outside air, and the incubation layer 40 will not be deprived of oxygen during the incubation process.

[0041] In this embodiment, to facilitate the replacement of materials in the incubation layer 40, a material gate for opening and closing is provided on the side of the incubation layer 40. Specifically, the incubation layer 40 further includes a material gate 401, which is located on one side of the incubation layer 40. The horizontal side of the material gate 401 is hinged to the incubation layer 40, and the other horizontal end of the material gate 401 is detachably and fixedly connected to the incubation layer 40 by a latch, so as to open or close the material gate 401. The material gate 401 is opened to replace the material, and then the material gate 401 is closed.

[0042] In other embodiments, the incubation layer 40 is detachably and fixedly provided with a temperature sensor 90 and a humidity sensor 11, which are used to test the temperature and humidity inside the incubation layer 40, respectively; the temperature and humidity measured by the temperature sensor 90 and the humidity sensor 11 are transmitted to the controller, and the operator can make manual intervention based on the temperature and humidity inside the incubation layer 40.

[0043] For example, when the internal temperature of the incubation layer 40 is too high, a fan is placed next to the device to increase air circulation and remove heat.

[0044] For example, when the humidity inside the incubation layer 40 is too high, some dry material is added manually and mixed with the material inside the incubation layer 40 to lower the humidity. Conversely, when the humidity inside the incubation layer 40 is too low, some moist material is added manually and mixed with the material inside the incubation layer 40 to raise the humidity.

[0045] In this embodiment, the present invention also includes glass plates 12, and there are two or more glass plates 12. The glass plates 12 are located above the first mesh 10 or at the bottom of the incubation layer 40. The glass plates 12 are installed at the top and bottom of the device to improve the stability of the device. In other embodiments, wooden boards with the same shape as the glass plates 12 can also be used as substitutes.

[0046] In this embodiment, the present invention also includes several screws 70 and fixing holes 80. Fixing holes 80 are provided on the side plates at each corner of the incubation layer 40. Second fixing holes are also provided on the first mesh 10 and the second mesh 30 corresponding to the fixing holes 80. The screws 70 pass through the first mesh 10, the second mesh 30, the incubation layer 40, and the glass plate 12 in sequence, and are fixed at both ends with nuts. The wave plate 20 is constrained between the first mesh 10 and the second mesh 30, so as to realize the series fixation of the first mesh 10, the wave plate 20, the second mesh 30, the incubation layer 40, and the glass plate 12.

[0047] As one possible implementation of the first mesh 10 and the second mesh 30, the density of the first mesh 10 and the second mesh 30 is 200 mesh or more; this ensures oxygen circulation and avoids local hypoxia. At the same time, the black soldier fly eggs are small and have a low enough density, so that the black soldier fly eggs can stably adhere to the second mesh 30.

[0048] Furthermore, the materials of the first mesh 10 and the second mesh 30 are preferably the same as those used for screens, including but not limited to polyurethane rubber, steel bars, and stainless steel; they have a certain strength and are not easily broken, etc.

[0049] In this embodiment, the wave plate 20 is composed of a curved plate 201 and vertical portions 202 fixed at both ends of the curved plate 201. The vertical portions 202 have a second fixing hole that runs vertically through the top and bottom, so that when the upper and lower ends of the wave plate 20 contact the first mesh 10 and the second mesh 30 respectively, several cavities similar to triangular prisms can be formed to attract black soldier fly larvae.

[0050] In one specific embodiment, the side profile of the curve plate 201 is a cosine function curve or a continuous triangular curve.

[0051] As one possible specific implementation of this embodiment, the horizontal width L1 of the egg collection chamber 60 is greater than 4cm; the height of the wave plate should be between 1cm and 3cm; the vertical height of the hatching layer should be greater than 2cm; these dimensions are designed to better attract black soldier flies and avoid local hypoxia.

[0052] As one possible specific structure of the incubation layer 40, the lower end of the inner wall of the incubation layer 40 is provided with an extension 13. The extension 13 is used to support the wave plate 20 in the incubation state. The wave plate 20 is at a certain height from the bottom of the incubation layer 40 to allow the black soldier fly larvae to move around after hatching, thereby increasing the survival rate.

[0053] Specific usage steps:

[0054] Step 1: Assemble the device. Select one or more trapping and hatching structures. Each trapping and hatching structure is clearly assembled in the order of first mesh 10, wave plate 20, second mesh 30, and hatching layer 40. Install the glass plate 12 at the top and bottom of the device. Align the fixing holes 80 and second fixing holes on several trapping and hatching structures. Use screws 70 to pass through from top to bottom and lock them with nuts at both ends of the screws 70.

[0055] Step 2: Add decomposed materials, such as rotten kitchen waste, to the first mesh 10 inside the hatching layer 40 to attract black soldier flies to lay eggs in the egg collection chamber 60.

[0056] Step 3: After egg laying is complete, following Step 1, remove the screw 70, first mesh 10, corrugated plate 20, and second mesh 30 in reverse order. Remove the material from the first mesh 10, move the second mesh 20 down onto the next layer of the first mesh 10, and invert the second mesh 20 so that the black soldier fly eggs face upwards. Replace the material in the hatching layer 40 with hatching aids to facilitate the hatching of the black soldier fly eggs. Next, invert the corrugated plate 20 and place it on the extension of the hatching layer 40 so that there is a certain height between the corrugated plate 20 and the second mesh 20, allowing the hatched black soldier fly larvae to move around, thereby increasing the survival rate. Note that during the hatching process, place this device in a basin to prevent the black soldier fly eggs from escaping after hatching and becoming difficult to collect.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
