Description

Technical Field

[0001] This invention mainly relates to the field of insect breeding equipment, specifically to an automatic picking and placing conveying device for insect breeding, and also to an insect breeding system. Background Technology

[0002] In today's society, insect farming has certain industrial and economic value. For example, mealworms are the most ideal feed insects for artificial breeding. They are highly nutritious and can be used directly as live animal protein feed for frogs, turtles, scorpions, centipedes, ants, high-quality fish, ornamental birds, medicinal animals, valuable fur-bearing animals, and rare livestock and poultry. Moreover, after processing, they can be used in the food, health product, and cosmetic industries. Because their protein content ranks first among various live animal protein feeds, they are known as a "treasure trove of protein feed."

[0003] Taking the mealworm as an example, its life cycle consists of four parts: egg, larva, pupa, and adult. Its breeding begins with the eggs. Once mature, the larvae can be used for commercial purposes such as pet breeding. Pupae and adults are used for breeding stock for the next batch. During the larval growth process, the larvae gradually increase in size, requiring a continuous increase in breeding area to ensure the stocking density remains within a certain range; otherwise, they will crowd each other, severely affecting growth. Simultaneously, during growth, they produce frass and molt multiple times, requiring timely separation. This is because: firstly, the separated frass and molts can be used for other commercial production, such as frass to make fertilizer and molts to make medicine, generating immediate commercial value; secondly, failure to separate them will negatively impact the breeding environment, occupy breeding space, and consequently, adversely affect growth. Existing technologies employ multi-level breeding racks, with multiple breeding trays placed on each rack from top to bottom. Some racks hold a dozen or even dozens of breeding trays for artificial breeding. While this saves space, it presents the following technical problems:

[0004] 1. Manually retrieving and delivering trays is extremely labor-intensive, making the farming process very arduous. Because the farming racks are very high, stairs or frames need to be erected manually to retrieve and deliver multiple levels of farming trays. The trays themselves are difficult to move, and the added effort of climbing ladders and stairs makes the labor extremely strenuous, resulting in very low efficiency and making farming very arduous.

[0005] Second, there is a risk of people slipping and falling when manually retrieving and delivering the trays. Alternatively, the trays may tilt, causing the insects to fall out.

[0006] Third, because the breeding trays on the breeding racks require manual changing periodically (as the worms grow larger), manual feeding, and manual sifting of worm bodies, excrement, and exoskeletons, the multi-layered stacking method is highly unfavorable for these three operations. This not only leads to low work efficiency and high labor intensity but may also cause problems such as uneven feeding and insufficient sifting. Furthermore, this manual tray-removing and transferring method results in a low level of automation and intelligence, preventing the formation of automated production lines, low worm production efficiency, and an inability to meet commercial demands. Summary of the Invention

[0007] The technical problem solved by this invention is to provide an automatic picking and releasing transmission device for insect breeding that is convenient and quick to operate, highly intelligent and automated, has a high utilization rate of breeding area, good breeding effect, can greatly reduce the intensity of manual labor, and can be well adapted to automated breeding systems. In addition, an insect breeding system is also provided.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] An automatic picking and placing conveying device for insect breeding includes a frame installed on one side of a multi-level breeding rack. The frame is equipped with a tray picking mechanism for picking up and placing breeding trays. The tray picking mechanism includes a support seat that can be raised and lowered within the frame and a push-pull component that can be moved back and forth on the support seat. The support seat is used to be raised and lowered to the vicinity of the breeding trays on any layer of the breeding rack. At least one end of the push-pull component is provided with a connecting component, which is used to connect with the breeding trays on the same layer so that the breeding trays on the breeding rack can be pulled onto the support seat by the push-pull component, or to disconnect the connection after the push-pull component pushes the breeding trays on the support seat onto the breeding rack.

[0010] As a further improvement of the present invention, the support base is provided with a plurality of universal balls for supporting the push-pull assembly and the breeding tray, so that the breeding tray can be moved in the front-to-back direction on the support base under the drive of the push-pull assembly / or the breeding tray can be moved in the left-to-right direction on the support base under the drive of the external drive mechanism. At least one side of the frame along the left-to-right direction of the breeding tray is provided with a transfer port for docking with the outside, so that the support base can be docked with the external equipment to complete the transfer operation of the breeding tray.

[0011] As a further improvement of the present invention, the tray-retrieving mechanism includes two parallel limiting rods. The two limiting rods are vertically arranged above the support seat along the direction of translation of the push-pull assembly, and are used to form a limiting space between the limiting rods and the support seat to limit the upper and lower positions of the push-pull assembly and the breeding tray.

[0012] As a further improvement of the present invention, a rack is provided on the top surface of each of the two limiting rods along the axial direction. The push-pull assembly includes a push-pull plate that translates within the limiting space. A transmission horizontal shaft and a first motor assembly for driving the transmission horizontal shaft to rotate are installed on the push-pull plate. A gear is provided at both ends of the transmission horizontal shaft for meshing with the two racks respectively.

[0013] As a further improvement of the present invention, a protruding limiting seat is installed on the push-pull plate near the two limiting rods. The limiting seat has a through hole for the transmission horizontal shaft to pass through, so as to reduce the shaking of the transmission horizontal shaft during transmission. The two limiting seats respectively make limiting contact with the side walls of the two limiting rods to reduce the shaking in both directions when the push-pull plate moves.

[0014] As a further improvement of the present invention, the connecting component includes one or more electromagnets for adsorbing and fixing the breeding tray when energized.

[0015] As a further improvement of the present invention, the frame is provided with multiple vertically arranged slide rails, each slide rail is provided with a slider, and each slider is connected to the tray retrieval mechanism to limit the lifting and lowering of the tray retrieval mechanism.

[0016] As a further improvement of the present invention, a lifting drive assembly is installed on the top of the frame. The lifting drive assembly includes a second motor, a double-gear sprocket, a single-gear sprocket, a counterweight, and two vertically arranged chains. The beginning ends of the two chains are respectively connected to the left and right sides of the tray-retrieving mechanism. The end of one chain meshes around the double-gear sprocket and then connects to the counterweight. The end of the other chain meshes around the single-gear sprocket and the double-gear sprocket in sequence and then connects to the counterweight. The second motor drives the double-gear sprocket to rotate, thereby simultaneously driving the two chains to move and raise or lower the tray-retrieving mechanism.

[0017] As a further improvement of the present invention, it also includes a track drive mechanism, which includes a roller drive assembly, a plurality of track wheels fixed to the bottom of the frame, and two or more ground rails laid along one side of a plurality of breeding racks. The roller drive assembly is fixed to the bottom of the frame and is used to drive the track wheels to move along the ground rails so that the frame moves along one side of the plurality of breeding racks.

[0018] An insect breeding system is provided with multiple multi-level breeding racks arranged in sequence. Each breeding rack has multiple breeding trays arranged from top to bottom. An automatic picking and placing conveying device for insect breeding as described in any of the above is provided on one side of the multiple breeding racks.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] Firstly, the automatic pick-up and delivery device of this invention has a matching lifting function and a forward and backward translational pick-up and delivery function, which enables the pick-up and delivery of breeding trays on any layer of the breeding rack. This completely eliminates the existing method of manual climbing up and down to pick up and deliver, which not only greatly reduces the difficulty of operation, but also greatly improves the efficiency of operation and greatly enhances the safety of operation.

[0021] Secondly, the automatic pick-and-place transfer device of the present invention, due to the special design of the push-pull component 22, can move back and forth, and both its front and rear ends can be equipped with connecting components 221. This allows the device to be installed between two breeding racks, which not only occupies less space, but also makes operation faster, requires less equipment investment, and increases work efficiency. At the same time, it makes the breeding methods more diversified and intelligent. For example, the breeding trays on the front breeding rack can be picked up and sent to another breeding rack at the rear, and the breeding trays on the two breeding racks can be interchanged.

[0022] Thirdly, the automatic pick-and-place conveyor of the present invention, with the cooperation and mutual support of the frame 1, the liftable support seat 21, and the push-pull component 22 that can move back and forth, realizes the automated transfer and pick-and-place of the complex breeding rack. This enables the device to automatically coordinate the breeding rack with other automated breeding equipment (such as automatic feeding equipment, automatic screening equipment, etc.), that is, to form an automatic flow connection between the breeding rack and other automated equipment (because automatic transfer and pick-and-place is the basic element to ensure the automated connection between various equipment), thereby effectively ensuring the realization of automated breeding.

[0023] Fourthly, the automatic pick-and-place transfer device of this invention features multiple universal balls 211 that allow for smoother movement of both the push-pull assembly 22 and the breeding tray when the push-pull assembly 22 drives the breeding tray, reducing friction and enabling faster translation. Simultaneously, the design of the multiple universal balls 211 and the transfer port allows the carrier 21 to interface with external equipment to complete the transfer of the breeding tray. This enables automated coordination between this device and other automated aquaculture equipment (such as automatic feeding equipment, automatic screening equipment, etc.).

[0024] Fifth, the insect breeding system of this invention has a small footprint, is easy and quick to operate, and has a high degree of automation and work efficiency. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figures 1 to 6 As shown, the present invention provides an automatic loading and unloading conveying device for insect farming, including a frame 1 (the multi-level farming rack is shown as A in the figure) installed on one side of a multi-level farming rack. Figure 1The machine has two parallel rows of breeding racks. Each vertical column of each row of breeding racks has multiple breeding trays for raising insects (as shown in Figure B). The vertical height of the frame 1 is between 1 meter and 10 meters. The frame 1 is equipped with a tray-retrieving mechanism 2 for placing and removing breeding trays. The tray-retrieving mechanism 2 includes a support base 21 that can be raised and lowered within the frame 1 and a push-pull assembly 22 that can move back and forth on the support base 21 (for clarity, arrow CD in the attached figure indicates the front-to-back direction of the forward and backward movement). The support base 21 is used to raise and lower itself to the vicinity of any layer of breeding trays on the breeding rack. At least one end of the push-pull assembly 22 has a connecting component 221, which connects to the breeding trays on the same layer so that the breeding trays on the breeding rack can be pulled onto the support base 21 by the push-pull assembly 22, or disconnects the connection after the push-pull assembly 22 pushes the breeding trays on the support base 21 onto the breeding rack. The specific implementation principle is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, when it is necessary to remove the top-level breeding tray (E is defined as the breeding tray in the figure) on the first vertical column of the breeding rack, the support seat 21 first rises to the vicinity of the top-level breeding tray on the breeding rack, and then the push-pull component 22 on the support seat 21 moves forward (arrow C is the forward direction), so that the connecting component 221 at the front end of the push-pull component 22 and the breeding tray are connected. Then the push-pull component 22 moves backward and back (arrow D is the backward direction), and drives the breeding tray to move backward together, finally pulling the breeding tray from the breeding rack onto the support seat 21. Figure 4 This is a diagram showing the state when the push-pull assembly 22 pulls the breeding tray B out of the breeding rack A. For ease of understanding, some parts of the structure of the breeding rack A are omitted in the diagram, with only the two support rods on the breeding rack used to hold the breeding trays remaining to represent the breeding rack A.

[0038] Once the breeding tray is pulled onto the support seat 21, the support seat 21 lowers the breeding tray to a suitable height for manual feeding, sifting, or repotting. When it is time to return to its original position after the work is completed, the support seat 21 raises the breeding tray to the top of the breeding rack. Then, the push-pull component 22 on the support seat 21 pushes the breeding tray forward again. After the breeding tray is moved to the top of the breeding rack, the connecting component 221 stops connecting with the breeding tray, and then the push-pull component 22 moves backward independently.

[0039] This automatic pick-and-place conveyor can be used with a single breeding rack, or as... Figure 1As shown, this automatic pick-and-place conveyor is positioned between two breeding racks, meaning it can be used simultaneously on both front and rear breeding racks. The push-pull assembly 22 has connecting components 221 at both ends, allowing the push-pull assembly 22 on the support 21 to move forward to pick up and deliver the breeding tray E, and also to move backward to pick up and deliver the breeding tray F from the other breeding rack. This not only reduces the footprint, makes operation faster, and requires less equipment investment, but also increases efficiency. Simultaneously, it makes breeding methods more diverse and intelligent; for example, the breeding trays on the front breeding rack can be transferred to another breeding rack at the rear, and the breeding trays on the two racks can be interchanged. Furthermore, because this automatic pick-and-place conveyor can achieve rapid, multi-level pick-and-place operations, it can form excellent automatic docking with other automated equipment, such as... Figure 5 As shown in Figure G, this is an automatic screening and feeding device located on one side of the frame 1 (G is a separate, independent device; its specific structure will not be described here). This device can automatically dock with it, lifting and lowering the breeding trays from any layer to the automatic screening and feeding device. After screening and feeding by this device, the trays are automatically returned to the breeding rack (possibly returning to their original position or to another pre-set location). Through this unique scientific design, the device offers the following technical advantages:

[0040] Firstly, the automatic pick-up and delivery device of this invention has a matching lifting function and a forward and backward translational pick-up and delivery function, which enables the pick-up and delivery of breeding trays on any layer of the breeding rack. This completely eliminates the existing method of manual climbing up and down to pick up and deliver, which not only greatly reduces the difficulty of operation, but also greatly improves the efficiency of operation and greatly enhances the safety of operation.

[0041] Secondly, the automatic pick-and-place transfer device of the present invention, due to the special design of the push-pull component 22, can move back and forth, and both its front and rear ends can be equipped with connecting components 221. This allows the device to be installed between two breeding racks, which not only occupies less space, but also makes operation faster, requires less equipment investment, and increases work efficiency. At the same time, it makes the breeding methods more diversified and intelligent. For example, the breeding trays on the front breeding rack can be picked up and sent to another breeding rack at the rear, and the breeding trays on the two breeding racks can be interchanged.

[0042] Thirdly, the automatic pick-and-place conveyor of the present invention, with the cooperation and mutual support of the frame 1, the liftable support seat 21, and the push-pull component 22 that can move back and forth, realizes the automated transfer and pick-and-place of the complex breeding rack. This enables the device to automatically coordinate the breeding rack with other automated breeding equipment (such as automatic feeding equipment, automatic screening equipment, etc.), that is, to form an automatic flow connection between the breeding rack and other automated equipment (because automatic transfer and pick-and-place is the basic element to ensure the automated connection between various equipment), thereby effectively ensuring the realization of automated breeding.

[0043] like Figure 3 , Figure 4 As shown, further, in a preferred embodiment, the support base 21 is provided with a plurality of universal balls 211 for supporting the push-pull assembly 22 and the breeding tray, so that the breeding tray can be translated in the front-to-back direction on the support base 21 under the drive of the push-pull assembly 22 / or the breeding tray can be translated in the left-to-right direction on the support base 21 under the drive of the external drive mechanism (regarding the direction of left-to-right translation, for ease of understanding of the drawings, as shown). Figure 1 (The arrow HL shown in the figure indicates the left and right direction). At least one side of the frame 1 along the left and right translation direction of the breeding tray is provided with a transfer port for docking with the outside, so that the carrier 21 can dock with the external equipment to complete the transfer operation of the breeding tray.

[0044] In this embodiment, the frame 1 has four vertical rods, making it a frame-like structure. This frame-like structure has four open side walls (front, back, left, and right). The front and back openings allow the push-pull assembly 22 to move the breeding tray in and out of the frame 1, while the left and right openings facilitate the left-right translation of the breeding tray on the support 21 under the drive of the external drive mechanism. Figure 5 The transfer port is located at point K, and it docks with other automated equipment G nearby. In other embodiments, if the frame 1 has left and right side walls (for example, for sealing or aesthetic reasons), at least one side of the left and right side walls has a transfer port for docking with the outside. Regarding the support base 21, in this embodiment, as shown in the figure, the support base 21 consists of four horizontal frame edges, forming a frame shape, with multiple universal balls 211 mounted on the top surface of each frame edge. Of course, in other embodiments, the support base 21 can also be a square plate, forming a plate shape, with multiple universal balls 211 mounted on the top surface of the plate; such simple variations should fall within the scope of protection of this invention.

[0045] Because the support base 21 is equipped with multiple omnidirectional balls 211, the push-pull assembly 22 and the breeding tray can move more smoothly when driving the breeding tray, reducing friction and making translation faster. More importantly, when the breeding tray is translated onto the support base 21, if external equipment picks up or sends the breeding tray from the transfer port in the left or right direction (at this time, the connecting component 221 on the push-pull assembly 22 will inevitably stop connecting with the breeding tray), the multiple omnidirectional balls 211 can also ensure that the breeding tray can quickly move from the transfer port in the left or right direction. For example, the breeding tray can be pulled outward from the transfer port to the outside of the frame 1 for automatic screening and feeding, and then pushed inward from the transfer port onto the support base 21.

[0046] Through the above-mentioned special scientific design, firstly, the multiple omnidirectional balls 211 enable the push-pull assembly 22 and the breeding tray to move more smoothly when driving the breeding tray, reducing friction and making translation faster. Secondly, the coordinated design of the multiple omnidirectional balls 211 and the transfer port allows the carrier 21 to dock with external equipment to complete the transfer operation of the breeding tray (not just vertical transport). The breeding tray has the possibility of moving in multiple directions, which means that this device can be automatically coordinated with other automated breeding equipment (such as automatic feeding equipment, automatic screening equipment, etc.).

[0047] like Figure 3 , Figure 4 As shown, further, in a preferred embodiment, the tray-retrieving mechanism 2 includes two parallel limiting rods 23. These two limiting rods 23 are vertically positioned above the support seat 21 along the direction of translation of the push-pull assembly 22, forming a limiting space between the limiting rods 23 and the support seat 21 to limit the upper and lower positions of the push-pull assembly 22 and the breeding tray. This ensures that the breeding tray is limited on the support seat 21, making lifting and transport more stable and safer, and allowing for more precise docking of the support seat 21 (e.g., docking with a placement position on the breeding rack). Simultaneously, the upper and lower limiting method does not obstruct the forward, backward, left, and right translational directions of the breeding tray, effectively ensuring the realization of forward, backward, left, and right translational movements.

[0048] like Figure 3 , Figure 4As shown, in a preferred embodiment, each of the two limiting rods 23 has a rack 231 axially arranged on its top surface. The push-pull assembly 22 includes a push-pull plate 222 that translates within the limiting space. A transmission horizontal shaft 223 and a first motor assembly 224 for driving the transmission horizontal shaft 223 to rotate are mounted on the push-pull plate 222. Each end of the transmission horizontal shaft 223 has a gear 2231 for meshing with the two racks 231 respectively. In this embodiment, as shown, a transmission gear is located in the middle of the transmission horizontal shaft 223. The first motor assembly 224 is a forward and reverse drive motor, and the gear on its drive shaft meshes with the transmission gear in the middle of the transmission horizontal shaft 223. When the first motor assembly 224 drives the transmission horizontal shaft 223 to rotate, the gears 2231 at both ends of the transmission horizontal shaft 223 and the two racks 231 form a rack and pinion engagement, thereby enabling the push-pull plate 222 to translate in the forward and backward direction within the limiting space. This structural form is simple and low in cost. Secondly, it can ensure synchronous operation on both sides through a single transmission horizontal shaft 223, thereby ensuring the stable push-pull operation of the push-pull plate 222.

[0049] like Figure 3 , Figure 4 As shown, further, in a preferred embodiment, a protruding limiting seat 225 is installed on the push-pull plate 222 near each of the two limiting rods 23. The limiting seat 225 has a through hole for the transmission horizontal shaft 223 to pass through, reducing the shaking of the transmission horizontal shaft 223 during transmission. The two limiting seats 225 respectively make limiting contact with the side walls of the two limiting rods 23 to reduce lateral shaking when the push-pull plate 222 moves. The limiting seats 225 serve two purposes: first, they facilitate the installation of the transmission horizontal shaft 223, ensuring stable operation of the transmission horizontal shaft 223 without shaking; second, they can form a limiting fit with the limiting rods 23 on both sides, preventing lateral shaking of the push-pull plate 222 during push-pull operation, thus enabling precise docking with the breeding tray and accurately driving the breeding tray in push-pull motion.

[0050] Furthermore, in a preferred embodiment, the connecting component 221 includes one or more electromagnets for adsorbing and fixing the breeding tray when energized. Since the breeding tray is metal, when the push-pull plate 222 pushes the connecting component 221 into contact with the breeding tray, the connecting component 221 is energized, firmly connecting the breeding trays together to enable subsequent push-pull operations. Of course, in other embodiments, the connecting component 221 can also be configured in other forms, such as a pneumatic suction cup that firmly adsorbs and fixes the breeding tray after contact; or an electric hook that rotates to hook and fix the breeding tray.

[0051] like Figures 2 to 4As shown, in a preferred embodiment, the frame 1 is provided with multiple vertically arranged slide rails 11, each slide rail 11 containing a slider. Each slider is connected to the tray-retrieving mechanism 2 to limit the lifting and lowering of the tray-retrieving mechanism 2. This provides a stable limit for the tray-retrieving mechanism 2, ensuring that it does not shake during lifting and remains stable during push-pull operations after lifting and lowering stops, thereby achieving safe and stable tray retrieval and delivery.

[0052] like Figure 2 , Figure 5 As shown, in a preferred embodiment, a lifting drive assembly 3 is installed on the top of the frame 1. The lifting drive assembly 3 includes a second motor 31, a double-gear sprocket 32, a single-gear sprocket 33, a counterweight 34, and two vertically arranged chains 35. The beginning ends of the two chains 35 are respectively connected to the left and right sides of the tray-retrieving mechanism 2. The tail end of one chain 35 meshes around the double-gear sprocket 32 ​​and connects to the counterweight 34. The tail end of the other chain 35 meshes around the single-gear sprocket 33 and the double-gear sprocket 32 ​​in sequence and connects to the counterweight 34. The second motor 31 drives the double-gear sprocket 32 ​​to rotate, thereby simultaneously driving the two chains 35 to move and raise or lower the tray-retrieving mechanism 2. The counterweight 34 can reduce the torque of the second motor 31. Through the drive of the second motor 31, the double-gear sprocket 32 ​​can simultaneously drive the two chains 35 to move synchronously, thereby driving the left and right sides of the tray-retrieving mechanism 2 to achieve smooth and synchronous raising and lowering. Meanwhile, in this embodiment, a tension gear is provided in the attachment of the single gear sprocket 33. The tension gear meshes with the chain 35 and can adjust the tension of the chain 35, thereby adjusting the cooperation relationship between the two chains 35 and ensuring that the disk lifting mechanism 2 can achieve smooth lifting and lowering.

[0053] like Figure 6 As shown in the figures, in a preferred embodiment, a track drive mechanism 4 is also included. (For clarity of the accompanying drawings) Figure 6 The rest of the frame 1 is hidden, leaving only the bottom portion. The track drive mechanism 4 includes a roller drive assembly 41, multiple track wheels 42 fixed to the bottom of the frame 1, and two or more ground rails 43 laid along one side of multiple breeding racks. The roller drive assembly 41 is fixed to the bottom of the frame 1 and drives the track wheels 42 to move along the ground rails 43, thereby moving the frame 1 along one side of multiple breeding racks. This allows the device to not only perform multi-level vertical transport of a single breeding rack, but also to move along one side of multiple breeding racks, thus enabling the transport of multiple breeding racks, resulting in a wider range of applications and higher levels of automation and efficiency. In this embodiment, as... Figure 5As shown, the track drive mechanism 4 also includes a ceiling track fixed above the factory building. The ceiling track and the ground track 43 are parallel. The top of the frame 1 is equipped with a pulley assembly that cooperates with the ceiling track, so that the frame 1 runs along the ground track 43 below and the ceiling track above at the same time, making the operation more stable, safer, and preventing tipping.

[0054] Inspired by the above-disclosed technical features and embodiments, the present invention also proposes another implementation for the rack 1 and the tray-retrieving mechanism 2, as follows:

[0055] like Figure 7 , Figure 8 As shown, the tray-retrieving mechanism 2 also includes a drawer-shaped mounting box. The mounting box has transfer ports at its front and rear ends and on its right side, facilitating the movement of the breeding rack in and out under the push-pull assembly 22, and allowing the breeding tray to move horizontally to the right under the drive of the external drive mechanism. The structure of the support seat 21, the limiting rod 23, and the push-pull assembly 22 remains unchanged; they are all housed within the mounting box. Because of the integrated mounting box, the frame 1 differs from its previous structure. It only requires two vertical slide rails, each containing a slider for connection to one side of the mounting box. The integrated mounting box ensures the stability of the support seat 21, the limiting rod 23, and the push-pull assembly 22 within the box. The lifting drive assembly 3 is also not located at the top of the frame. As shown in the figure, the lifting drive assembly includes two vertically arranged annular chains, both of which are connected to the mounting box. Two synchronous gears are provided at both the top and bottom of the frame for engaging and limiting the movement of the two annular chains respectively. A lifting drive motor assembly is also provided at the bottom of the frame to simultaneously drive the two synchronous gears at the bottom of the frame to rotate, thereby raising and lowering the mounting box via the two annular chains. This structural design allows the lifting drive assembly to be installed at the bottom of the frame, resulting in a lower center of gravity and more stable operation.

[0056] This invention also provides an insect breeding system, which includes multiple multi-level breeding racks arranged in sequence. Each rack has multiple breeding trays arranged from top to bottom, and one side of each rack is equipped with an automatic retrieval and conveying device for insect breeding, as described above. In this embodiment, two rows of multi-level breeding racks share a single automatic retrieval and conveying device for insect breeding, maximizing the utilization of the breeding area. Through these features, the system occupies a small area, is easy and quick to operate, and has a high degree of automation and efficiency.
