Description

Technical Field

[0001] The invention belongs to the technical field of black soldier fly breeding, and particularly relates to a black soldier fly conservation device and a conservation method thereof. Background Art

[0002] Black soldier fly larvae can feed on organic waste, such as kitchen waste and livestock and poultry feces, and convert organic waste into insect feces and highly nutritious insect bodies. Insect feces are natural organic fertilizers, and the insect bodies contain high protein and high energy. They can not only be directly used as feed for the aquaculture industry to reduce aquaculture costs, but also can be used to extract biochemical raw materials such as antimicrobial peptides and chitin, with huge room for value-added. In the breeding process of black soldier fly larvae, many breeding steps require manual auxiliary operations, resulting in high labor intensity, low work efficiency, poor production process stability, and the quality of product insects cannot be guaranteed. For example, in the breeding process, it is necessary to add a corresponding weight of feed to feed according to the unit number of eggs, and in the prior art, feed addition generally adopts manual addition, and this single and repeated weighing operation is manually performed, which has high labor intensity, and manual weighing and adding are also prone to errors and deviations, resulting in feed weight not meeting production process requirements, affecting production. Summary of the invention

[0003] The purpose of the present invention is to provide a technical solution of black soldier fly conservation equipment and a conservation method thereof in view of the shortcomings of the prior art. The overall structural design is ingenious and reasonable, the practicability is strong, the overall management and breeding measures are convenient, the quality of insect egg conservation is guaranteed, and the labor cost investment in the entire conservation process is small, the labor intensity is reduced, the efficiency is improved, and large-scale production is possible to improve economic benefits.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A black soldier fly incubation device comprises a conveyor belt mechanism, a pushing mechanism, a weighing mechanism, a leveling mechanism and an unpowered roller conveyor line. The conveyor belt mechanism realizes the transmission of a black soldier fly incubation box. The pushing mechanism is arranged at the output end of the conveyor belt mechanism. The pushing mechanism receives the black soldier fly incubation box transmitted by the conveyor belt mechanism. The weighing mechanism comprises a weighing platform and a screw feeder. The weighing platform is arranged at the output end of the pushing mechanism. The pushing mechanism pushes the black soldier fly incubation box onto the weighing platform. The screw feeder adds feed into the black soldier fly incubation box. The leveling mechanism is arranged at the output end of the weighing platform. The leveling mechanism presses down and levels the feed in the black soldier fly incubation box. The unpowered roller conveyor line temporarily stores the black soldier fly incubation box after the feed is leveled.

[0005] A conservation method based on a black soldier fly conservation device comprises the following steps: Step 1: Select feed and add it into the feed bin of the screw feeder; Step 2: The conveyor belt mechanism is started to convey the black soldier fly incubator toward the push platform at a conveying speed of 0.4m / s to 1m / s. When a black soldier fly incubator is conveyed to the push platform, the black soldier fly incubator slides toward the inclined lower end of the push platform due to the inclined design of the push platform until the black soldier fly incubator hits the side baffle and moves into place on the push platform. Step 3: When the photoelectric sensor at the inclined lower end of the push platform senses that a black soldier fly incubator is in place on the push platform, the conveyor belt mechanism stops running and the rodless cylinder is started at the same time. The rodless cylinder drives the push frame to move toward the weighing platform through the slider. The push frame pushes the black soldier fly incubator toward the weighing platform synchronously while moving until the black soldier fly incubator is completely pushed onto the weighing platform. The moving speed of the push frame is 0.8m / s to 2m / s. Step 4: When the photoelectric sensor on the weighing platform senses that a black soldier fly incubator is in place on the weighing platform, the screw feeder starts, and feed is added to the black soldier fly incubator on the weighing platform through the screw feeder's auger tube, and the weighing sensor at the bottom of the weighing platform senses the weight until the feed in the black soldier fly incubator reaches the set weight, and the screw feeder stops; Step 5: When the screw feeder is started, the rodless cylinder drives the push frame to move away from the weighing platform and reset through the slider; Step 6: After the push rack is reset, start the conveyor mechanism to push another black soldier fly incubator onto the push table. Under the inclined design of the push table, the black soldier fly incubator slides toward the inclined lower end of the push table until the black soldier fly incubator hits the side baffle and moves into place on the push table. Step 7: When the photoelectric sensor senses that a black soldier fly incubator is in place on the push table, the conveyor belt mechanism stops running and the rodless cylinder is started at the same time. The rodless cylinder drives the push frame to move through the slider to move the black soldier fly incubator on the push table toward the weighing table. When the black soldier fly incubator on the push table gradually moves toward the weighing table, the black soldier fly incubator with feed added on the weighing table will be pushed to the lower pressure area simultaneously. When the black soldier fly incubator on the push table is completely moved to the weighing table, the black soldier fly incubator with feed added on the weighing table will also be pushed into the lower pressure area; Step 8: When the photoelectric sensor 2 in the lower pressure zone senses that a black soldier fly incubator is in place in the lower pressure zone, the lower pressure assembly is started, and the piston rod of the lifting cylinder extends to push the lower pressure plate downward to press down and level the feed in the black soldier fly incubator in the lower pressure zone. After the feed is leveled, the piston rod retracts and returns to its original position; Step 9: Repeat the actions of steps 4 to 8 above. When the black soldier fly incubator with added feed on the weighing table moves to the downward pressure area, the black soldier fly incubator with pressed feed in the downward pressure area will be pushed to the buffer zone at the same time. When the black soldier fly incubator with flat feed completely moves to the buffer zone, add eggs to the black soldier fly incubator at the buffer zone. Step 10: Repeat the above step 9. When the black soldier fly incubator after the feed is pressed in the lower pressing area moves to the buffer area, the black soldier fly incubator after the eggs are added in the buffer area will be pushed to the unpowered roller conveyor line for storage; Step 11: Repeat the actions in step 10 above. When the black soldier fly incubator on the unpowered roller conveyor line is full, transfer the black soldier fly incubator on the unpowered roller conveyor line to the incubation workshop and incubate for 4 days at an ambient temperature of 25-30℃ and a humidity of 60-85%.

[0006] The present invention has the following beneficial effects due to the adoption of the above technical solution: The overall structural design of the present invention is ingenious and reasonable, with strong practicality, convenient overall management and feeding measures, ensuring the quality of insect egg conservation, and less labor cost input in the entire conservation process, reducing labor intensity, improving efficiency, and enabling large-scale production to improve economic benefits.

[0007] In the equipment of the present invention, the push platform, the weighing platform, the placement area, and the unpowered roller conveyor line are arranged on the same straight line, the conveyor belt mechanism and the push platform are arranged vertically, the conveyor belt mechanism conveys the black soldier fly incubator to the push platform, and the conveyor belt mechanism only conveys one black soldier fly incubator to the push platform at a time. When the black soldier fly incubator is in place on the push platform, the rodless cylinder cooperates with the pushing frame to push the black soldier fly incubator on the push platform to the weighing platform of the next station, and then the screw feeder puts the black soldier fly incubator in place on the weighing platform Feed is added to the black soldier fly incubator until the fixed amount is reached. During the feed addition, the rodless cylinder drives the push rack to move and reset. When the push rack resets, the conveyor mechanism transports another black soldier fly incubator to the push table. Then the reset push rack continues to push the black soldier fly incubator to the weighing table, thereby synchronously pushing the black soldier fly incubator on the weighing table that has been fed to the lower pressure area. The lower pressure plate in the lower pressure area presses down and flattens the feed in the black soldier fly incubator, while the synchronous screw feeder continues to add feed and push the rack. After the conveyor belt mechanism transports another black soldier fly incubator to the push platform, when the push rack pushes the black soldier fly incubator, the push platform, the weighing platform, and the black soldier fly incubator in the pressing area will move synchronously, so that the push platform, the weighing platform, and the black soldier fly incubator in the pressing area move to the next station step by step, so that the black soldier fly incubator in the pressing area moves to the buffer zone, and the eggs are added to the black soldier fly incubator in the buffer zone. The eggs can be added manually or with the help of automated equipment. Automatic addition, when the subsequent push rack pushes a new black soldier fly incubator to move, the black soldier fly incubators in the push platform, weighing platform, pressing area, and buffer zone will be synchronously moved to the next station step by step, so that the black soldier fly incubators in the buffer zone are moved to the unpowered roller conveyor line for storage. The whole process is cleverly and reasonably designed. During the incubation process, the black soldier fly incubator is moved from the weighing platform to the pressing area, from the pressing area to the buffer zone, and from the buffer zone to the unpowered roller conveyor line without power, which is only achieved by the push of the push rack. When the unpowered roller conveyor line is full, the black soldier fly incubators on the unpowered roller conveyor line are transferred to the incubation workshop. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] like Figure 1 and Fig.26 As shown, a black soldier fly incubation device of the present invention includes a conveyor belt mechanism 1, a push mechanism 2, a weighing mechanism 3, a leveling mechanism 6 and an unpowered roller conveyor line 7. The conveyor belt mechanism 1 realizes the transmission of the black soldier fly incubator. The push mechanism 2 is arranged at the output end of the conveyor belt mechanism 1. The push mechanism 2 receives the black soldier fly incubator transmitted by the conveyor belt mechanism 1. The weighing mechanism 3 includes a weighing platform 4 and a screw feeder 5. The weighing platform 4 is arranged at the output end of the push mechanism 2. The push mechanism 2 pushes the black soldier fly incubator to the weighing platform 4. On the platform 4, the screw feeder 5 adds the feed into the black soldier fly incubator, and the leveling mechanism 6 is arranged at the output end of the weighing platform 4. The leveling mechanism 6 presses down and levels the feed in the black soldier fly incubator, and the unpowered roller conveyor line 7 temporarily stores the leveled feed in the black soldier fly incubator. The equipment also includes a workbench 36, and the workbench 36 is provided with a mounting base plate 37. The pushing mechanism 2, the weighing platform 4 and the leveling mechanism 6 are all fixedly arranged on the mounting base plate 37, and the mounting base plate 37 is also provided with a control panel 17. The screw feeder 5 is used to realize the automatic addition process of the feed, reduce the labor intensity of manual labor, and improve work efficiency. The discharge port of the screw feeder 5 is provided with a vertical section, and the vertical section is just above the weighing platform 4, so that the feed can be added to the black soldier fly incubator on the weighing platform 4 in an orderly and smooth manner, reducing splashing and scattering during the feed addition process.

[0011] The pushing mechanism 2 includes a pushing platform 8, a pushing frame 9 and a rodless cylinder 10. A photoelectric sensor 11 is arranged on the pushing platform 8. The pushing frame 9 is connected to a slider 49 of the rodless cylinder 10. The rodless cylinder 10 drives the pushing frame 9 to move horizontally along the length direction of the pushing platform 8, and pushes the black soldier fly incubator on the pushing platform 8 to the weighing platform 4. The rodless cylinder 10 is used as a driving mechanism, which has high transmission efficiency and can quickly push the pushing frame 9 to perform precise displacement to improve efficiency. The two ends of the rodless cylinder 10 are fixed to the mounting base 37 by screws of the fixing seat 48 to ensure the firmness and reliability of the installation, and it is easy to disassemble and assemble. The pushing frame 9 is preferably assembled by a horizontal plate 38 and a vertical plate 39. The flat plate 38 and the vertical plate 39 are fixed with screws to form a stable pushing rack 9 structure. The structure is firm and not prone to deformation or loosening, which is more conducive to the rodless cylinder 10 cooperating with the pushing rack 9 to stably push the black soldier fly incubator. The horizontal plate 38 and the slider 49 are also fixed with screws to achieve screw fixation of the pushing rack 9 and the slider 49 to ensure the connection strength. The photoelectric sensor 11 can detect the position and status of the black soldier fly incubator so as to perform the next operation on the black soldier fly incubator. When the photoelectric sensor 11 senses that a black soldier fly incubator is in place on the pushing platform 8, the rodless cylinder 10 will start and cooperate with the pushing rack 9 to push the black soldier fly incubator out of the pushing platform 8 after it is in place, thereby ensuring the overall operation safety and stability.

[0012] The push platform 8 is tiltedly arranged on the mounting seat 12, and the photoelectric sensor 11 is arranged at the tilted lower end of the push platform 8. A side baffle 13 is arranged on the tilted lower end side of the push platform 8, and the conveyor belt mechanism 1 is arranged on the tilted high end side of the push platform 8. There are two mounting seats 12, and the push platform 8 is tiltedly supported on the two mounting seats 12 to ensure the strength and stability of the overall structure. The two mounting seats 12 are fixed with screws to the mounting base plate 37, which effectively ensures the installation firmness and reliability of the push platform 8 on the mounting base plate 37, improves the structural safety, and is also convenient for actual assembly and disassembly. A weight reduction hole 47 is provided on the mounting seat 12 to optimize the structure and facilitate the screw installation of the mounting seat 12 and the mounting base plate 37 and other components. At the same time, the tilted setting of the push platform 8 can be more conducive to receiving the black soldier fly incubator transmitted by the conveyor belt mechanism 1, which is convenient for black soldier fly incubator. The box is moved and positioned on the pushing platform 8. When the conveyor belt mechanism 1 pushes the black soldier fly incubator box onto the pushing platform 8, under the inclined setting of the pushing platform 8, the black soldier fly incubator box will slide and abut against the inclined lower end of the pushing platform 8, thereby realizing the accurate positioning of the black soldier fly incubator box on the pushing platform 8. After the black soldier fly incubator box is moved into place on the pushing platform 8, the rodless cylinder 10 cooperates with the pushing frame 9 to push the black soldier fly incubator box to the weighing platform 4, thereby realizing the automatic pushing of the black soldier fly incubator box. No manual handling is required, the labor intensity is reduced, and the work efficiency is improved. The design of the side baffle 13 can prevent the black soldier fly incubator box from sliding off from the inclined lower end, thereby improving the overall safety. The black soldier fly incubator box slides toward the inclined lower end of the pushing platform 8 under the inclined design of the pushing platform 8, and the black soldier fly incubator is accurately positioned on the pushing platform 8 when it hits the side baffle 13.

[0013] The leveling mechanism 6 includes a support assembly 14 and a pressing assembly 15. The support assembly 14 includes two symmetrically arranged support seats 16. A placement area is formed between the two support seats 16. The placement area includes a buffer zone 18 and a pressing zone 19. The pressing assembly 15 is arranged at the pressing zone 19. The pressing zone 19 is arranged at the output end of the weighing platform 4. The buffer zone 18 is arranged at the input end of the unpowered roller conveyor line 7. The pressing zone 19 is provided with a photoelectric sensor 44. The support seat 16 is fixed to the mounting base plate 37 by screws to ensure the firmness of the installation. A placement area is formed between the two support seats 16 for firmly supporting the black soldier fly incubator. The placement area is divided into a buffer zone 18 and a pressing zone 19. The pressing zone 19 is close to the weighing platform 4 and is just located at the output of the weighing platform 4. The buffer zone 18 is close to the non-powered roller conveyor line 7 and is located at the input end of the non-powered roller conveyor line 7. The design is reasonable and meets the whole incubation process. The support seat 16 is also provided with a baffle 46. The baffle 46 limits the black soldier fly incubator so that the black soldier fly incubator can only move along the length direction of the placement area to improve the operation safety. The support seat 16 is provided with a short partition 45 at the end close to the weighing platform 4 to ensure that the black soldier fly incubator on the weighing platform 4 will not contact the black soldier fly incubator in the placement area, and ensure the sensing accuracy and precision of the weighing sensor assembly 24 on the weighing platform 4. The support seat 16 is provided with a weight reduction hole 47 to save materials, optimize the structure, and also facilitate the screw installation operation of the support seat 16 and the mounting base plate 37 and other components. The photoelectric sensor 44 can detect the position and state of the black soldier fly incubator. When the photoelectric sensor 4 senses that there is a black soldier fly incubator in place on the pressing area 19, the pressing assembly 15 will start.

[0014] The down-pressing assembly 15 includes a mounting frame 20, a lifting cylinder 21 and a down-pressing plate 22. The mounting frame 20 is horizontally mounted at the down-pressing area 19. The lifting cylinder 21 is fixed on the mounting frame 20. The lifting cylinder 21 is connected to the down-pressing plate 22. The down-pressing plate 22 is arranged above the down-pressing area 19. The lifting cylinder 21 drives the down-pressing plate 22 to move toward the black soldier fly incubator in the down-pressing area 19, so that the down-pressing plate 22 presses down on the feed in the black soldier fly incubator. The piston rod of the lifting cylinder 21 moves up and down, so that the down-pressing plate 22 moves up and down synchronously. The downwardly moving down-pressing plate 22 presses down and flattens the feed in the black soldier fly incubator, which helps to evenly distribute the subsequent black soldier fly larvae and avoid local over- or under-feeding, thereby improving the overall utilization rate of the feed. Moreover, it can avoid uneven feed accumulation and water accumulation, maintain the hygiene of the breeding environment, and ensure the quality of worm egg conservation. The mounting frame 20 is fixed to the mounting base plate 37 by screws to ensure the installation firmness and reliability of the down-pressing component 15. The mounting frame 20 is designed as two vertical mounting plates 40 and a horizontal cross-bracket 41. The cross-bracket 41 is fixedly arranged between the two mounting plates 40. The lifting cylinder 21 is fixed on the cross-bracket 41. The mounting plate 40 is provided with a long groove-shaped mounting hole 42. The cross-bracket 41 is fixedly connected to the mounting hole 42 of the mounting plate 40 by a bolt assembly. Due to the long groove design, the height position of the bolt assembly in the mounting hole 42 is adjustable, so that the height of the cross-bracket 41 can be adjusted to meet different installation requirements and expand the scope of application. A reinforcing plate 43 is also provided on the mounting plate 40. The reinforcing plate 43 is fixedly connected to the mounting base plate 37 to further enhance the overall structural strength and bearing capacity of the mounting frame 20, meet the installation requirements of the lifting cylinder 21, and improve the structural safety and reliability. The mounting plate 40 and the reinforcing plate 43 are both provided with weight-reducing holes 47, which save materials, optimize the structure, and facilitate the presetting of the holes on each plate, so as to cooperate with the screws to realize the assembly of the mounting frame 20 itself and the assembly of the mounting frame 20 and the mounting base plate 37. The rodless cylinder 10 and the lifting cylinder 21 are both provided with displacement sensors 23, which can accurately control the stroke position of the cylinder to ensure that the push frame 9 and the lower pressure plate 22 move in place, avoid production delays and waste caused by inaccurate movement of the push frame 9 and the lower pressure plate 22, and improve the safety and reliability of the entire childcare process.

[0015] A weighing sensor assembly 24 is provided at the bottom of the weighing platform 4. The weighing sensor assembly 24 includes a weighing sensor 25, a top support plate 26 and a bottom support plate 27. The top support plate 26 is fixed to the weighing platform 4 with screws. A top limit groove 28 is provided on the bottom surface of the top support plate 26, and a bottom limit groove 29 is provided on the top surface of the bottom support plate 27. The top limit of the weighing sensor 25 is clamped in the top limit groove 28, and the bottom limit of the weighing sensor 25 is clamped in the bottom limit groove 29. The weighing sensor 25 is fixed to the top support plate 26 and the bottom support plate 27 with screws. The weighing sensor assembly 24 can monitor the weight change on the weighing platform 4 in real time to ensure that the black soldier fly incubator is stable. Feed is added to the set weight to ensure production. The design of the top limit groove 28 and the bottom limit groove 29 can achieve accurate card connection and positioning between the weighing sensor 25 and the top support plate 26 and the bottom support plate 27. The weighing sensor 25 that is carded in place is fixed to the top support plate 26 and the bottom support plate 27 with screws to ensure the reliability and stability of the overall assembly. It is also beneficial to ensure the accuracy of the weighing of the weighing sensor 25 and avoid errors caused by improper installation of the weighing sensor 25. Screws are also used to fix the top support plate 26 and the weighing platform 4, and the bottom support plate 27 and the mounting base plate 37 to ensure the firmness of the installation and facilitate subsequent maintenance and replacement.

[0016] A guide support round rod 30 is arranged on the weighing platform 4, and the guide support round rod 30 is evenly distributed along the width direction of the weighing platform 4. A flat section 31 is arranged on the bottom surface of the guide support round rod 30, and the guide support round rod 30 is supported and attached to the weighing platform 4 by the flat section 31, and the guide support round rod 30 is fixed to the weighing platform 4 with screws. The design of the guide support round rod 30 can enhance the overall structural stability and bearing capacity of the weighing platform 4, and the round rod design can be more conducive to the black soldier fly incubator being pushed onto the weighing platform 4, reducing the resistance and friction during the pushing process of the black soldier fly incubator, and the design of the flat section 31 can increase the contact area between the guide support round rod 30 and the weighing platform 4, improve the supporting stability of the guide support round rod 30 on the weighing platform 4, and be more conducive to the positioning and installation of the guide support round rod 30 on the weighing platform 4, and at the same time, the flat section 31 can also facilitate the processing of the threaded hole.

[0017] A beam photoelectric sensor 32 is provided on the weighing platform 4, and the beam photoelectric sensor 32 includes a transmitter 33 and a receiver 34. Side guard plates 35 are provided on both sides of the weighing platform 4. The transmitter 33 and the receiver 34 are respectively arranged on the two side guard plates 35. The beam photoelectric sensor 32 can detect the black soldier fly incubator on the weighing platform 4. When the beam photoelectric sensor 32 senses that there is a black soldier fly incubator on the weighing platform 4, the screw feeder 5 is started to add materials into the black soldier fly incubator.

[0018] A conservation method based on a black soldier fly conservation device comprises the following steps: Step 1: Select feed and add it to the feed bin of the screw feeder 5. The humidity of the feed is controlled at about 75%. The feed is mainly composed of food waste processed by a three-phase centrifuge; Step 2: The conveyor belt mechanism 1 is started to convey the black soldier fly incubator toward the push platform 8 at a conveying rate of 0.4 m / s to 1 m / s to ensure a smooth and safe conveying process. When a black soldier fly incubator is conveyed to the push platform 8, the black soldier fly incubator slides toward the inclined lower end of the push platform 8 due to the inclined design of the push platform 8 until the black soldier fly incubator hits the side baffle 13 and the black soldier fly incubator moves into place on the push platform 8. Step 3: When the photoelectric sensor 11 at the inclined lower end of the pushing platform 8 senses that a black soldier fly incubator is in place on the pushing platform 8, the conveyor belt mechanism 1 stops running and the rodless cylinder 10 is started at the same time. The rodless cylinder 10 drives the pushing frame 9 to move toward the weighing platform 4 through the slider 49. The pushing frame 9 pushes the black soldier fly incubator toward the weighing platform 4 synchronously during the movement until the black soldier fly incubator is completely pushed onto the weighing platform 4. The moving speed of the pushing frame is 0.8m / s to 2m / s, which ensures the stability and safety of the black soldier fly incubator during the pushing process. Step 4: When the photoelectric sensor 32 on the weighing platform 4 senses that a black soldier fly incubator is in place on the weighing platform 4, the screw feeder 5 starts, and the feed is added to the black soldier fly incubator on the weighing platform 4 through the screw auger of the screw feeder 5, and the weighing sensor 25 at the bottom of the weighing platform 4 senses the weight until the feed in the black soldier fly incubator is added to the set weight, the screw feeder 5 stops, and the black soldier fly incubator is set to add 8kg of feed at a time, and the feed humidity is about 75%; the weighing sensor has high precision to ensure the accuracy of the weighing result, ±0.5% sensitivity error, and has good linear characteristics, ±0.1% fs nonlinearity; Step 5: When the screw feeder 5 is started, the rodless cylinder 10 drives the push frame 9 to move away from the weighing platform 4 through the slider 49 and reset; Step 6: After the push rack 9 is reset, the conveyor belt mechanism 1 is started to push another black soldier fly incubator onto the push platform 8. Under the inclined design of the push platform 8, the black soldier fly incubator slides toward the inclined lower end of the push platform 8 until the black soldier fly incubator hits the side baffle 13 and moves into place on the push platform 8; Step 7: When the photoelectric sensor 11 senses that the black soldier fly incubator is in place on the push platform 8, the conveyor belt mechanism 1 stops running and the rodless cylinder 10 is started at the same time. The rodless cylinder 10 drives the push frame 9 to move through the slider 49, and moves the black soldier fly incubator on the push platform 8 toward the weighing platform 4. When the black soldier fly incubator on the push platform 8 gradually moves toward the weighing platform 4, the black soldier fly incubator with added feed on the weighing platform 4 will be pushed to the downward pressure area 19 synchronously. When the black soldier fly incubator on the push platform 8 is completely moved to the weighing platform 4, the black soldier fly incubator with added feed on the weighing platform 4 is also pushed into the downward pressure area 19; Step eight: when the photoelectric sensor 2 44 of the lower pressure area 19 senses that a black soldier fly incubator is in place in the lower pressure area 19, the lower pressure assembly 15 is started, and the piston rod of the lifting cylinder 21 is extended to push the lower pressure plate 22 downward to press down and level the feed in the black soldier fly incubator in the lower pressure area 19. After the feed is leveled, the piston rod retracts and returns to its original position; the leveling mechanism adopts a pneumatic drive mode and pneumatic control, which has a simple structure, convenient operation, high control accuracy, and is convenient for precise control of the leveling tension. The air pressure range of the pneumatic control is 0.15-1MPa, which ensures the normal operation and safety of the leveling mechanism. The leveling tension control range is 98N-687N, which ensures the leveling effect of the feed. The stroke range is 0-105mm, which ensures that the leveling operation of the feed in the black soldier fly incubator can be achieved within this stroke range; Step 9: Repeat the actions of steps 4 to 8 above. When the black soldier fly incubator with added feed on the weighing platform 4 moves to the downward pressure area 19, the black soldier fly incubator with pressed feed in the downward pressure area 19 will be pushed to the buffer area 18 synchronously. When the black soldier fly incubator with flattened feed is completely moved to the buffer area 18, 15g of eggs are added to the black soldier fly incubator at the buffer area 18. The eggs are eggs that have been hatched for 48 hours. The eggs need to be incubated before they are added. The incubation steps are as follows: collect the eggs in the egg-laying room, weigh and package the collected eggs, and add 30g of corn starch to each 15g egg portion. Then put the packaged eggs into the incubator for incubation. Set the incubator temperature to 28°C and the humidity to 60%. Incubate for 48 hours, so that the eggs finally added to the black soldier fly incubator are 15g eggs after 48 hours of incubation. The weighing instrument used for weighing eggs has functions such as automatic zeroing and automatic tracking, including the instrument's weighing linear compensation and power-off data retention functions, which improves the reliability and accuracy of the measurement; Step 10: Repeat the above step 9. When the black soldier fly incubator after the feed is pressed in the lower pressing area 19 moves to the buffer area 18, the black soldier fly incubator after the eggs are added in the buffer area 18 will be pushed synchronously to the unpowered roller conveyor line 7 for storage; Step 11: Repeat the actions of step 10 above. When the black soldier fly incubator on the unpowered roller conveyor line 7 is full, transfer the black soldier fly incubator on the unpowered roller conveyor line 7 to the incubation workshop and incubate for 4 days at an ambient temperature of 25-30°C and a humidity of 60-85%.

[0019] In the equipment of the present invention, the push platform 8, the weighing platform 4, the placement area, and the unpowered roller conveyor line 7 are arranged on the same straight line, and the conveyor belt mechanism 1 is vertically arranged with the push platform 8. The conveyor belt mechanism 1 conveys the black soldier fly incubator to the push platform 8. The conveyor belt mechanism 1 only conveys one black soldier fly incubator to the push platform 8 at a time. When the black soldier fly incubator is in place on the push platform 8, the rodless cylinder 10 cooperates with the pushing frame 9 to push the black soldier fly incubator on the push platform 8 to the next station weighing platform 4, and then the screw feeder 5 pushes the black soldier fly incubator in place on the weighing platform 4. The black soldier fly incubator is added with feed to a fixed amount. During the feed addition, the rodless cylinder 10 drives the push rack 9 to move and reset. After the push rack 9 is reset, the conveyor mechanism 1 transports another black soldier fly incubator to the push platform 8. Then, the reset push rack 9 continues to push the black soldier fly incubator to the weighing platform 4, thereby synchronously pushing the black soldier fly incubator on the weighing platform 4 after the feed has been added to the lower pressing area 19. The lower pressing plate 22 of the lower pressing area 19 presses down and flattens the feed in the black soldier fly incubator, and the synchronous screw feeder 5 continues to add feed and the push rack 9 moves. After reset, when the conveyor mechanism 1 delivers another black soldier fly incubator to the push platform 8, when the push frame 9 pushes the black soldier fly incubator, the push platform 8, the weighing platform 4, and the black soldier fly incubator in the lower pressure area 19 will be synchronously moved, so that the black soldier fly incubators in the push platform 8, the weighing platform 4, and the lower pressure area 19 will move to the next station step by step, so that the black soldier fly incubator in the lower pressure area 19 will move to the buffer area 18, and the eggs will be added to the black soldier fly incubator in the buffer area 18. The eggs can be added manually or automatically with the help of automated equipment. In addition, when the subsequent push rack 9 pushes a new black soldier fly incubator to move, the black soldier fly incubators in the push platform 8, the weighing platform 4, the down-pressing area 19, and the buffer zone 18 will be synchronously moved step by step to the next station, so that the black soldier fly incubators in the buffer zone 18 are moved to the unpowered roller conveyor line 7 for storage. The whole process is cleverly and reasonably designed. During the incubation process, the black soldier fly incubator is moved from the weighing platform 4 to the down-pressing area 19, from the down-pressing area 19 to the buffer zone 18, and from the buffer zone 18 to the unpowered roller conveyor line 7 without power, which is only achieved by the movement of the push rack 9. When the unpowered roller conveyor line 7 is full, the black soldier fly incubators on the unpowered roller conveyor line 7 are transferred to the incubation workshop.

Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
