Description

Technical Field

[0001] The present invention relates to the technical field of insect breeding, and in particular to an intelligent feeding system for a black soldier fly breeding box and a working method. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The black soldier fly (Hermetia illucens) is one of the few animals capable of consuming food waste. Due to its biological characteristics, environmental safety, wide feeding range, and diverse utilization, it has been extensively studied in the management of urban food waste and livestock manure. Compared to traditional farming methods, automated black soldier fly farming offers advantages such as reduced human involvement, a better operating environment, and high efficiency. Automated black soldier fly farming equipment and production lines are also developing rapidly.

[0004] The inventors found that in the black soldier fly automated breeding equipment, most of the black soldier fly breeding feeding methods still adopt manual periodic feeding or fixed point one-time feeding. This not only increases labor costs, but also often leads to the escape of black soldier fly larvae due to exhaustion of food, or excessive feeding makes it difficult to effectively separate the insects, raw materials, and insect sand, which ultimately affects the black soldier fly yield; in addition, the black soldier fly breeding stage will produce an odor represented mainly by NH3, which will cause problems such as low willingness to operate manually and the spread of foul gas. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a black soldier fly breeding box intelligent feeding system and working method. In combination with the temperature changes during the insect activities during the breeding process, the feeding is linked to the biological activities of the black soldier flies during the breeding process, so as to independently complete the automatic feeding of black soldier fly raw materials, reduce the difficulty of manual operation, enhance the automatic feeding capacity, control the feed amount in real time and accurately, improve the efficiency of black soldier flies in disposing of organic waste, and solve the problem of low black soldier fly output rate of existing automated breeding equipment.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] In the first aspect, the present invention provides an intelligent feeding system for a black soldier fly breeding box, comprising a control center, a feed pipe and a breeding box, wherein the feed pipe is located above the breeding box, an electric valve is provided on the feed pipe, and a temperature detection element is provided inside the breeding box, the electric valve and the temperature detection element are both connected to the control center, the control center is provided with a monitoring temperature range, and the control center controls the opening of the electric valve according to the monitored temperature.

[0008] As a further implementation, the breeding box is composed of a first side panel, a second side panel and a bottom panel, the first side panel and the second side panel are vertically fixed on the bottom panel, and the bottom panel has a slope toward the center.

[0009] As a further implementation, a temperature detection element is fixedly provided at the center of the bottom plate, and the temperature detection element is higher than the top surface of the bottom plate.

[0010] As a further implementation, both sides of the base plate are upwardly convex arc structures, and both sides of the bottom of the base plate are provided with grooves.

[0011] As a further implementation, the side panels at the grooves on both sides of the bottom plate extend downwardly from the bottom plate.

[0012] As a further implementation, the tops of the first side panel and the second side panel both have edges that are curved toward the interior of the breeding box.

[0013] As a further implementation, the second side panel is a movable panel structure.

[0014] As a further implementation, a movement auxiliary structure is installed in the groove.

[0015] In a second aspect, the present invention provides a working method of an intelligent feeding system for a black soldier fly breeding box, the specific process of which is as follows:

[0016] First, manually put the first batch of raw materials and black soldier fly larvae into the breeding box;

[0017] The temperature detection element transmits the temperature signal to the control center, which compares the acquired temperature with the set temperature range and generates a control signal to control the start and stop of the electric valve.

[0018] As a further implementation, when the detected temperature falls within a set temperature range, the electric valve opens;

[0019] When the detected temperature is lower than the set temperature range, the electric valve is closed. After the temperature of the pile drops to room temperature, the breeding box is taken out, the second side panel is opened, and the insect sand in the breeding box is taken out.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The present invention sets a temperature detection element in the breeding box, and connects the temperature detection element and the electric valve on the feeding pipe to the control center. By monitoring the temperature of the material pile in the breeding box, utilizing the biological characteristics of black soldier fly larvae being gluttonous and pre-pupae being anorexic, and combining the characteristics that black soldier fly larvae are prone to generate heat during feeding activities, the temperature in the material pile is linked to the electric valve. After reaching the set temperature, the electric valve opens and feeds into the breeding tank, realizing real-time feeding according to the feeding needs of the black soldier fly larvae; when the temperature of the material pile drops, it indicates that the black soldier fly has entered a relatively anorexic stage, that is, it has turned into a pre-pupae stage, and the linked electric valve is closed and feeding is stopped. The whole process realizes the purpose of automatic feeding and controlling residual material, and achieves a balance between improving the efficiency of black soldier fly disposal of kitchen waste and effectively screening insect sand in the later stage, reducing the cost of manual participation.

[0022] (2) The two sides of the bottom plate of the present invention are upwardly protruding arc structures, so that the two sides of the bottom of the bottom plate have groove structures, which makes it convenient for the breeding box to be fixed on the breeding rack and can be moved according to needs. At the same time, the protruding structures on both sides of the top of the bottom plate can limit the crawling of black soldier flies, effectively preventing the escape of black soldier fly larvae.

[0023] (3) The top of the side panel of the present invention has an edge, which is a structure curved toward the bottom panel and has a smooth curvature. Because the surface of the structure is smooth, it is difficult for the black soldier fly larvae to climb onto the top of the side panel of the breeding box. Even if the black soldier fly larvae can climb to the edge structure, they will slide down due to a certain curvature, thereby preventing the black soldier fly larvae from climbing out from the top, thereby increasing the efficiency of disposing of kitchen waste.

[0024] (4) The breeding box of the present invention has a simple structure. The side panel on one side of the breeding box can be movably disassembled, which facilitates the cleaning and material removal of the breeding box. The grooves on both sides of the bottom of the breeding box can be customized with pulleys, chains and other movable auxiliary structures according to needs to increase the degree of automation of the overall equipment and reduce manual participation.

[0030] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0031] As introduced in the background technology, most of the existing black soldier fly automated breeding equipment still adopts the method of manual periodic feeding or fixed-point one-time feeding, which not only increases labor costs, but also often leads to the escape of black soldier fly larvae due to exhaustion of food or excessive feeding, resulting in the difficulty in effectively separating the worms, raw materials, and worm sand, which ultimately affects the black soldier fly yield; in addition, the black soldier fly breeding stage will produce an odor mainly represented by NH3, which will cause low manual operation willingness and the leakage of foul-smelling gas. In order to solve the above technical problems, the present invention proposes a black soldier fly breeding box intelligent feeding system and working method.

[0032] Example 1

[0033] In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, an intelligent feeding system for a black soldier fly breeding box is proposed, comprising a feeding pipe 2, a control center 3 and a breeding box 5, wherein an electric valve 1 is provided on the feeding pipe 2, and a temperature sensor 11 is provided on the breeding box 5. The electric valve 1 and the temperature sensor 11 are both connected to the control center 3 via a connecting line 4. The control center 3 detects the temperature in the breeding box 5 and controls the opening of the electric valve 1 according to the temperature, so as to control the feeding of feed according to the temperature changes generated by biological activities, thereby linking the feeding with the biological activities of black soldier flies during the breeding process.

[0034] Insects are cold-blooded animals that lack their own temperature regulation mechanisms, but they can generate heat through their own behavior, and their body temperature generally depends on the environment they are in. During the process of black soldier flies disposing of kitchen waste, the temperature of the pile continues to increase due to the active feeding activities of the black soldier fly larvae during their growth period, and it is maintained for a period of time during the most active feeding stage of the black soldier flies. However, during the growth period of the black soldier fly larvae, their mouthparts will degenerate to a certain extent, and they will no longer feed. When the feeding activity decreases or even stops, the temperature of the pile will decrease due to the influence of the ambient temperature. The inactive feeding period is also the period when the black soldier fly larvae mature and are about to enter the pre-pupa stage. Therefore, the temperature of the raw material can be used to reflect the feeding activity of the black soldier flies.

[0035] like Figure 2 As shown, the breeding box 5 is composed of a first side panel 7, a second side panel 8 and a bottom panel 10. There are three first side panels 7 and one second side panel 8. Both the first side panel 7 and the second side panel 8 are fixedly arranged on the bottom panel 10 to serve as side walls of the breeding box 5.

[0036] Among them, the second side panel 8 is a movable panel structure, which can be pulled out to facilitate the removal of larvae, insect sand and material piles in the breeding box 5. In this embodiment, the second side panel 8 is a structure that slides up and down. In other embodiments, the second side panel 8 can also be set to an opening and closing structure. The specific structural type can be set according to actual design requirements, and there are no excessive restrictions here.

[0037] The breeding box 5 is used to receive the first batch of feed and black soldier fly larvae. The bottom plate 10 is a structure with a downward depression in the center. Specifically, the bottom plate 10 has a slope toward the center to form a cone-shaped plane. A temperature sensor 11 is arranged in the center of the plane to detect the temperature of the material pile in the breeding box 5. The setting of the cone structure in the center of the breeding box 5 is conducive to the aggregation of the material pile and insects, and facilitates temperature monitoring.

[0038] The slope of the ground of the breeding box can be set according to the designed height of the material pile, but should not be too high to prevent the material and insects from piling up in the center of the bottom plate 10.

[0039] It is understandable that in other embodiments, the temperature sensor 11 can also be replaced by a temperature detection element such as a temperature control probe, as long as the temperature of the material pile in the breeding box 5 can be detected. No excessive restrictions are imposed here.

[0040] It should be noted that the temperature detection element installed at the center of the bottom plate 10 needs to be higher than the set distance of the top of the bottom plate 10. The specific distance is determined according to the thickness of the pile in the breeding box 5 to ensure the accuracy of temperature detection.

[0041] The first side panel 7 and the second side panel 8 are vertically arranged on the bottom panel 10, and together enclose a box structure with an upper opening. The connection between the two sides of the bottom panel 10 and the adjacent side panels is a raised and smooth connection, that is, the two sides of the bottom panel 10 are an upwardly raised arc structure, so that the two sides of the bottom of the bottom panel 10 have a groove 9 structure to facilitate the fixing of the breeding box 5 on the breeding rack and to move it according to demand. At the same time, the raised structures on both sides of the top of the bottom panel can limit the crawling of black soldier flies, effectively preventing the escape of black soldier fly larvae.

[0042] It is understandable that the grooves 9 on both sides of the bottom surface of the base plate 10 can be customized with pulleys, chains and other auxiliary facilities as needed to facilitate the movement of the breeding box 5 on the automatic breeding rack, increase the degree of automation of the overall equipment, and reduce manual participation.

[0043] like Figure 2As shown, the side panels at the grooves on both sides of the bottom plate 10 extend downward from the bottom plate 10 to limit the sides of the grooves, further improving the installation stability of the breeding box 5.

[0044] The tops of the first side panel 7 and the second side panel 8 both have an edge 6, which is a structure that bends toward the inside of the breeding box 5 and has a smooth curvature. At the same time, the first side panel 7 and the second side panel 8 both have smooth surfaces. Because the surface of the structure is smooth, it is difficult for the black soldier fly larvae to climb onto the top of the side panel of the breeding box 5. Even if the black soldier fly larvae can climb to the edge 6 structure, they will slide down due to a certain curvature, thereby preventing the black soldier fly larvae from climbing out from the top, thereby increasing the efficiency of disposing of kitchen waste.

[0045] The control center 3 is equipped with a temperature control system and an intelligent linkage system. The temperature control system is equipped with a monitoring temperature range, preferably 30℃ ~ 50℃. When 30℃≤temperature<50℃, the intelligent linkage system controls the electric valve 1 on the feed pipe 2 to feed at a fixed flow rate; when the temperature is >50℃, an early warning is activated and manual intervention is performed to prevent the larvae from dying due to excessively high temperature. When the reaction temperature of the pile gradually drops and is lower than 30℃, the electric valve 1 on the linkage feed pipe 2 is closed and feeding is stopped.

[0046] It should be noted that the electric valve 1 should not be fully opened. The optimal opening degree of the electric valve 1 is 30%. The opening degree of the valve is limited to ensure slow feeding to avoid the residual material remaining at the end due to one-time feeding, which affects the screening effect of the insect sand.

[0047] This embodiment utilizes the biological characteristics of black soldier fly larvae being gluttonous and prepupae being anorexic, combined with the fact that black soldier fly larvae easily generate heat during feeding activities, and links the temperature in the pile with the electric valve 1 of the feed pipe 2. When the set temperature is reached, the electric valve 1 opens to feed the breeding box 5, thereby achieving real-time feeding according to the feeding needs of the black soldier fly larvae.

[0048] When the temperature of the material pile drops, it means that the black soldier flies have entered the relatively anorexic stage, that is, the pre-pupa stage. The linked electric valve 1 is closed and the feeding is stopped. The whole process realizes the purpose of automatic feeding and control of residual material. The material can be automatically replenished according to the eating situation of the black soldier fly larvae, reducing the cost of human participation. At the same time, by setting the feed amount, the situation of excessive residual material caused by large-scale feeding is avoided, and a balance is achieved between the improvement of the efficiency of the black soldier flies in disposing of kitchen waste and the effective screening of insect sand in the later stage.

[0049] Example 2

[0050] In another typical embodiment of the present invention, a working method of the black soldier fly breeding box intelligent feeding system described in Example 1 is proposed, which is specifically as follows:

[0051] First, the first batch of raw materials and black soldier fly larvae are manually placed into the breeding box 5. Due to the gravity of the raw materials and the feeding habits of the black soldier fly larvae, the initial raw materials will accumulate in the area centered on the bottom of the cone. Therefore, the temperature of the pile can be detected by the temperature sensor 11.

[0052] As the black soldier fly larvae grow, their feeding activity increases, and their activity intensifies. The temperature of the pile gradually rises from room temperature. When the temperature reaches 30°C, the temperature sensor 11 transmits a signal to the control center 3, and the intelligent linkage system generates a control signal to control the opening of the electric valve 1 of the feed pipe 2. After the electric valve 1 is opened, the material is slowly fed through the feed pipe 2. At the same time, the temperature sensor 11 continuously detects the temperature of the pile and provides real-time feedback.

[0053] Due to the continuous feeding and the feeding habits of the black soldier fly larvae, the black soldier fly larvae continue to eat and generate heat, and the temperature of the pile gradually increases. When the black soldier fly gradually turns from the larval stage to the prepupa stage, the black soldier fly's feeding habits disappear due to its own biological characteristics, and the black soldier fly lacks relevant feeding activities, which causes the temperature of the pile to drop. When the temperature of the pile gradually drops below 30°C, the intelligent linkage system gives the electric valve 1 a closing signal, and the electric valve 1 slowly closes and stops feeding. After the temperature of the pile drops to room temperature, take out the breeding box 5, and take out the insect sand in the breeding box 5 through the second side plate 8 that is movable on one side.

[0054] Since the above process uses the biological activities of black soldier flies as monitoring items and the effectiveness of black soldier flies in treating kitchen waste is judged based on their biological characteristics, the biological characteristics of black soldier flies can be maximized to treat fine kitchen waste residues, while avoiding the phenomenon of difficulty in separating worms and sand caused by excessive raw materials and the situation of mixing raw materials.

[0055] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
