[0001] This utility model relates to the field of biological experimental technology, and more specifically, to an integrated device for attracting and collecting black soldier fly eggs. Background Technology
[0002] Black soldier flies are saprophytic insects belonging to the family Markidae. Their larvae are rich in nutrients such as protein, fat, and amino acids, making them a high-quality source of animal feed and a potential alternative to traditional feeds like fishmeal, thus possessing broad market prospects. Furthermore, the breeding of black soldier flies and the processing of organic waste can achieve resource utilization, reducing waste disposal costs and environmental pressure, and contributing to the promotion of a circular economy and sustainable development.
[0003] In order to gain a deeper understanding of the biological characteristics of black soldier flies and provide a theoretical basis for their application in various fields, research and experiments are usually conducted on various stages of black soldier flies. However, when conducting experiments on black soldier fly eggs, the collection of eggs is a major challenge.
[0004] Currently, black soldier flies used in experiments are usually kept inside transparent incubators to facilitate observation by staff. However, when inducing black soldier flies to lay eggs, staff need to place the egg-laying device inside the incubator. The current egg-laying device cannot effectively attract black soldier flies, making the egg-laying and egg collection process time-consuming. Therefore, it needs to be improved and optimized. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, this utility model provides an integrated device for attracting and collecting black soldier fly eggs, which has the advantage of good attraction and collection effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for attracting and collecting black soldier fly eggs, comprising an outer shell, an egg-laying chamber at the top of the outer shell, a collection chamber at the bottom of the outer shell, a partition fixedly installed on the left side of the outer shell, and a scraper fixedly installed on the right side of each set of partitions;
[0007] A partition plate is movably installed between each set of partitions. A first fixing plate is provided on the left side of the partition plate. A collection frame is movably installed inside the collection chamber. A mesh is provided inside the collection frame. A second fixing plate is fixedly installed on the left side of the collection frame. The second fixing plate is located on the left side wall of the outer shell.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 7 As shown, this utility model provides an integrated device for attracting and collecting black soldier fly eggs, including a shell 1, an egg-laying chamber 2 at the top of the shell 1, a collection chamber 3 at the bottom of the shell 1, a partition 4 fixedly installed on the left side of the shell 1, and a scraper 5 fixedly installed on the right side of each partition 4.
[0029] A partition plate 7 is movably installed between each set of partitions 4. A first fixing plate 6 is provided on the left side of the partition plate 7. A collection frame 8 is movably installed inside the collection chamber 3. A mesh 9 is provided inside the collection frame 8. A second fixing plate 10 is fixedly installed on the left side of the collection frame 8. The second fixing plate 10 is located on the left side wall of the outer shell 1.
[0030] Side panels 12 are fixedly installed on both the front and rear sides of the outer casing 1. A placement frame 13 is movably installed on the bottom of the side panel 12. A fluorescent lamp 15 is fixedly installed on the top of the side panel 12. An insect-proof board 14 is fixedly installed on the right side wall of the side panel 12. A vent 16 is fixedly installed inside the side panel 12. A fan blade 17 is rotatably installed inside the vent 16. A motor 18 is fixedly installed inside the vent 16. The output shaft of the motor 18 is fixedly connected to the fan blade 17.
[0031] When the device is in use, black soldier flies lay eggs between each set of partition plates 7. The eggs hang in the gaps between the partition plates 7. Before use, the operator can pull out the placement frame 13, put an appropriate amount of rotten food inside the placement frame 13, then reset the placement frame 13, and turn on the motor 18 and fluorescent light 15. The fluorescent light 15 attracts black soldier flies with its light, while the operation of the motor 18 drives the fan blade 17 to rotate. The fan blade 17 blows the odor of the rotten food on the placement frame 13 out through the insect-proof plate 14, further attracting black soldier flies with its odor. After the eggs are laid, the operator pulls out the first fixing plate 6, and the partition plates 7 move with the first fixing plate 6. Furthermore, the scraper 5 on the right side of each set of partition plates 4 scrapes away the eggs in the gaps of the partition plates 7 when they are pulled. After the partition plates 7 are completely removed, the eggs fall onto the top of the mesh 9. The operator can forcefully pull out the second fixed plate 10 to separate the first permanent magnet block 19 and the second permanent magnet block 20, thus completing the collection of insect eggs. After a single collection operation is completed, the operator can pull the lever 11 upward, and the further movable plate 27 will move upward along the fixed shell 26. The upward movement of the movable plate 27 will drive the wedge 24 upward, and the further wedge 24 will be stored inside the telescopic groove 23, allowing the operator to pull out the partition plate 7 to complete the disassembly. It is worth noting that the plastic material of the partition plate 7 has a longer service life, can be reused multiple times, and has a low water absorption rate, which will not affect the hatching rate of black fly eggs. After cleaning, the operator can align the partition plate 7 with the positioning groove 21, and after alignment, snap the partition plate 7 into the interior of the positioning groove 21. At this time, the outer wall of the partition plate 7 will squeeze the wedge 24 into the telescopic groove 23. When the fixed groove 22 and the telescopic groove 23 are aligned, the wedge 24 will be reset downward by the spring 25, completing the installation of the partition plate 7.
[0032] By using fluorescent lights 15 and vents 16, the fluorescent lights 15 attract black soldier flies with their light, while the vents 16 blow away the smell of rotting food from the placement frame 13, further attracting black soldier flies through their odor. After the black soldier flies have laid their eggs, the workers pull out the first fixing plate 6, allowing the eggs to be scraped off by the scraper 5 and fall onto the mesh 9 for collection. Compared to traditional devices, this device not only attracts black soldier flies with light and odor but also scrapes off all the eggs at once after they have laid them, ensuring thorough collection and improving efficiency.
[0033] The first fixing plate 6 has a positioning groove 21 on its right side that matches each set of partition plates 7, and the partition plates 7 and the positioning groove 21 are engaged with each other.
[0034] The top of the partition plate 7 has a fixing groove 22, the top of the positioning groove 21 has a telescopic groove 23, the inside of the telescopic groove 23 is movably installed with a wedge 24, the bottom of the wedge 24 and the fixing groove 22 abut against each other, and the top of the wedge 24 and the telescopic groove 23 are elastically connected by a spring 25.
[0035] After cleaning, the staff can align the partition plate 7 and the positioning groove 21, and then snap the partition plate 7 into the inside of the positioning groove 21. At this time, the outer wall of the partition plate 7 will squeeze the wedge 24 into the telescopic groove 23. When the fixing groove 22 and the telescopic groove 23 are aligned, the wedge 24 will be reset downward by the spring 25, thus completing the installation of the partition plate 7.
[0036] With the positioning groove 21, when the partition plate 7 needs to be installed, the staff can press the partition plate 7 to complete the engagement between the partition plate 7 and the positioning groove 21. By pulling the pull rod 11 upward, the wedge 24 is retracted into the telescopic groove 23, which further realizes the disassembly of the partition plate 7. Compared with the traditional wooden partition, the plastic partition can be quickly disassembled and reassembled, can be reused multiple times, and has a low water absorption rate, which will not affect the hatching rate of black fly after laying.
[0037] The second permanent magnet block 20 is fixedly installed at both the front and rear ends of the left side wall of the outer shell 1, and the first permanent magnet block 19 matching the second permanent magnet block 20 is opened at both the front and rear ends of the second fixing plate 10.
[0038] Workers can forcefully pull the second fixing plate 10 outward to separate the first permanent magnet block 19 and the second permanent magnet block 20, thus completing the collection of insect eggs.
[0039] The spacing between each set of partitions 7 is 1mm, and the partitions 7 are made of plastic.
[0040] The 1mm spacing between each set of partitions allows black soldier flies to lay their eggs. Plastic is used because it has a longer lifespan, can be reused multiple times, and has low water absorption, so it will not affect the hatching rate of the black soldier flies after they lay their eggs.
[0041] The top of the first fixing plate 6 is fixedly installed with a fixing shell 26, and a movable plate 27 is movably installed inside the fixing shell 26.
[0042] The top of the movable plate 27 is fixedly equipped with a pull rod 11, one end of which is located on the outside of the fixed shell 26. The bottom of the movable plate 27 extends through the interior of the telescopic groove 23 and is fixedly connected to the wedge 24.
[0043] The operator can pull the lever 11 upwards, and the further movable plate 27 will move upwards along the fixed shell 26. The upward movement of the movable plate 27 will drive the wedge 24 upwards, and the further wedge 24 will be stored inside the telescopic groove 23, so that the operator can pull the partition plate 7 outwards.
[0044] The placement frame 13 is used to collect spoiled food, and the left end of the fluorescent lamp 15 is bent upwards to attract black soldier flies from a greater distance.
[0045] Working principle and usage process of this utility model:
[0046] When the device is in use, black soldier flies lay eggs between each set of partition plates 7. The eggs hang in the gaps between the partition plates 7. Before use, the operator can pull out the placement frame 13, put an appropriate amount of rotten food inside the placement frame 13, then reset the placement frame 13, and turn on the motor 18 and fluorescent light 15. The fluorescent light 15 attracts black soldier flies with its light, while the operation of the motor 18 drives the fan blade 17 to rotate. The fan blade 17 blows the odor of the rotten food on the placement frame 13 out through the insect-proof plate 14, further attracting black soldier flies with its odor. After the eggs are laid, the operator pulls out the first fixing plate 6, and the partition plates 7 move with the first fixing plate 6. Furthermore, the scraper 5 on the right side of each set of partition plates 4 scrapes away the eggs in the gaps of the partition plates 7 when they are pulled. After the partition plates 7 are completely removed, the eggs fall onto the top of the mesh 9. The operator can forcefully pull out the second fixed plate 10 to separate the first permanent magnet block 19 and the second permanent magnet block 20, thus completing the collection of insect eggs. After a single collection operation is completed, the operator can pull the lever 11 upward, and the further movable plate 27 will move upward along the fixed shell 26. The upward movement of the movable plate 27 will drive the wedge 24 upward, and the further wedge 24 will be stored inside the telescopic groove 23, allowing the operator to pull out the partition plate 7 to complete the disassembly. It is worth noting that the plastic material of the partition plate 7 has a longer service life, can be reused multiple times, and has a low water absorption rate, which will not affect the hatching rate of black fly eggs. After cleaning, the operator can align the partition plate 7 with the positioning groove 21, and after alignment, snap the partition plate 7 into the interior of the positioning groove 21. At this time, the outer wall of the partition plate 7 will squeeze the wedge 24 into the telescopic groove 23. When the fixed groove 22 and the telescopic groove 23 are aligned, the wedge 24 will be reset downward by the spring 25, completing the installation of the partition plate 7.
