Description

Technical Field

[0001] This invention relates to the field of insect farming technology, specifically to a drag chain material conveying device and a sealed insect farming equipment. Background Technology

[0002] Insect farming has certain industrial and economic value. For example, black soldier flies are ideal feed insects in artificial breeding due to their high nutritional value. They can be used directly as live animal protein feed for chickens, frogs, turtles, scorpions, centipedes, ants, high-quality fish, ornamental birds, medicinal animals, valuable fur-bearing animals, and rare livestock and poultry. Furthermore, after processing, they can be used in the food, health product, and cosmetic industries. To increase yield and achieve large-scale farming, existing technologies include traditional box-type farming as well as farming plate or conveyor belt-type farming, thus enabling large-scale breeding. Organic waste used for insect farming is ubiquitous in daily life, such as kitchen waste like vegetable leaves, animal entrails, and fur from farmers' markets; leftover food from hotels and fast food restaurants; and solid food from supermarkets, dessert shops, and food processing plants. After being crushed and mixed, this organic waste can be transformed into viscoelastic material, the feed for insects. Viscoelastic material is a highly viscous, elastic fluid that can flow in pipes. Pipeline transport is the optimal method for conveying viscoelastic material, but current technology can only transport it to the required storage container via fixed pipes, and then further transfer it to breeding boards, breeding boxes, or conveyor belts using other equipment. In these feeding methods, the viscoelastic material may be exposed to the elements for extended periods during transport and storage before being fed, potentially causing air pollution. Furthermore, these methods require numerous auxiliary devices, are bulky, costly, and energy-intensive.

[0003] Specifically, to improve the utilization rate of breeding space, breeding boards are generally not used in single-layer breeding, but rather in a duplex configuration with upper and lower layers left for breeding, resulting in multiple layers of breeding boards. Within such a limited space, while keeping the breeding boards stationary, it is difficult to improve the efficiency of feeding. Dragging relatively long feeding pipes to deliver feed to the breeding boards is challenging, and the long, unfixed pipes are difficult to manage, resulting in an uneven feeding process. The manual labor required is significant, and even then, uniform feeding is not achieved. Even if feed is manually delivered to the breeding boards, uneven or intermittent accumulation necessitates subsequent spreading and even distribution, which is cumbersome and currently not feasible. Therefore, existing technologies for increasing breeding scale still rely on conveyor belts or manual feeding. Conveyor belt systems require complex mechanical structures, leading to high feeding costs, high energy consumption, and severe air pollution. Manual feeding is even more problematic. Furthermore, even automated existing feeding equipment cannot continuously supply material to the feeding device on the aquaculture platform because it cannot operate by dragging pipes directly onto the platform. Typically, material is fed at fixed points, resulting in a patchy accumulation that requires other equipment to even out the distribution, or the feeding device is refilled before feeding begins, only to be refilled again after the initial feeding, leading to extremely low efficiency. Therefore, designing a highly automated device with manageable feeding pipes, ensuring uniform and smooth feeding, and allowing direct feeding onto the aquaculture platform is essential. Summary of the Invention

[0004] In view of the problems in the related technologies, the present invention proposes a drag chain material conveying device for insect farming to overcome the above-mentioned technical problems existing in the existing related technologies.

[0009] Preferably, the outer end of the feeding bend is connected to a discharge mechanism.

[0010] Preferably, the discharge mechanism is a discharge pipe with multiple discharge ports that is connected to the discharge bend, or multiple discharge pipes connected to the discharge bend.

[0011] Preferably, the discharge mechanism includes a lead screw mounted on the unloading trolley, a movable slider mounted on the lead screw, and a feeding tube connected between the movable slider and the unloading bend.

[0012] Preferably, the guide tube is provided with at least one rotary channel, the feeding tube rotates through the rotary channel, and at least one guide wheel is provided on each side of the rotary channel and / or the rotary channel is a rotary pipe.

[0013] Preferably, the tube winding vehicle is provided with at least one rotary channel, the feeding tube rotates in different directions through the rotary channel, and at least one guide wheel is provided on each side of the rotary channel and / or the rotary channel is a rotary tube.

[0014] Preferably, the guide wheel includes at least one rotary guide wheel located inside the feed tube and a plurality of anti-deviation guide wheels located on the outside. A rotary channel is formed between the rotary guide wheel and the anti-deviation guide wheels, and at least one anti-deviation guide wheel is provided above and below the rotary guide wheel.

[0015] Preferably, the slewing guide wheel and the anti-deviation guide wheel correspond one-to-one to form a set of guide wheels, and the slewing channel includes at least three sets of guide wheels: upper, middle and lower, and the three sets of guide wheels are staggered to form a slewing channel that protrudes outward from the center.

[0016] Preferably, the drag chain material conveying device for insect farming includes two layers of guide rails arranged vertically, and also includes a lifting component for lifting the unloading trolley so that the unloading trolley connects with the guide rails of each layer.

[0017] Preferably, the lifting assembly includes a lifting and braking component and a support component on the lifting and braking component for supporting or suspending the unloading trolley. The support component is provided with a short rail that docks with the second guide rail. The unloading trolley is connected to the short rail and the second guide rail via rollers driven by the second drive motor.

[0018] Preferably, the bottom of the feeding vehicle is also provided with a material leveling component, which includes a material leveling shaft arranged axially perpendicular to the length direction of the guide rail and material feeding plates arranged sequentially on the material leveling shaft; or the material leveling component is a plurality of plowshares arranged sequentially, the plowshares gradually narrowing from back to front.

[0019] Preferably, the drag chain material conveying device for insect breeding also includes a steel wire rope (8) arranged parallel to the feeding pipe along the winding trajectory of the feeding pipe. The steel wire rope is also wound around the winding pipe cart and the guide pipe cart, and one end of the steel wire rope is fixed on the unloading cart and the other end is fixed corresponding to the feeding end of the feeding pipe.

[0020] A sealed insect breeding equipment includes the aforementioned drag chain material conveying device for insect breeding, and also includes a main frame, shelves, and breeding boards. The main frame has one or more shelves arranged vertically at intervals. The breeding boards are placed on the shelves. The parking rack is located at the end of the main frame. A second guide rail is provided above each shelf on the main frame, and the second guide rail is arranged along the length of the breeding board.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This application utilizes the coordination of the winding tube trolley and the unloading tube to ensure that the feeding tube remains taut at all times. This facilitates the transport and management of materials within the feeding tube, ensuring that the feed or insect feed mixture transported through the feeding tube is delivered smoothly and controllably to its intended location, and completely avoiding unnecessary exposure in space and time during the transport process. Specifically, when the unloading tube moves along guide rail two under the drive of drive motor two, it pulls the feeding tube. Because the feeding tube is wound around the guide tube trolley and the winding tube trolley twice in opposite directions, and the guide tube trolley remains stationary while the feeding tube is fixed at the feed inlet end of the breeding equipment, the pulling of the feeding tube simultaneously pulls the winding tube trolley to move in the opposite direction relative to the unloading tube along guide rail one. This increases the distance between the guide tube trolley and the unloading tube and shortens the distance between the guide tube trolley and the winding tube trolley, ensuring that the portion of the feeding tube within the insect breeding equipment remains orderly taut. This guarantees effective and efficient material distribution, and the equipment is simple with a small overall structure.

[0023] 2. This invention has a simple structure, low cost, good operating effect, stable and continuous material supply, and the material is not easily exposed. The feeding pipe is kept unobstructed and highly controllable. Attached Figure Description

[0043] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0044] Example 1:

[0045] A drag chain material conveying device includes a parking frame 1, a feeding pipe 2, a winding pipe trolley 3, a guide rail 1 4, a discharge trolley 5, a guide rail 2 6, a guide pipe trolley 301, a drive motor 1 10, and a drive motor 2 11. The discharge trolley can be mounted on the parking frame, and the guide pipe trolley is fixed on the parking frame. The feeding pipe is wound around the winding pipe trolley and the guide pipe trolley in sequence from the inlet end to the outlet end. The outlet end of the feeding pipe is connected to the discharge trolley. The winding pipe trolley can move along the guide rail 1 under the drive of the drive motor 1, and the discharge trolley can move along the guide rail 2 under the drive of the drive motor 2. The discharge trolley drags the feeding pipe forward while the winding pipe trolley moves in the opposite direction to the discharge trolley under the drive of the feeding pipe.

[0046] Generally, the above-mentioned insect farming involves spreading insects, feed, or a mixture of insects and feed on a farming board or in a farming box. In this application, we refer to the proportionally mixed insect-feed mixture or pure feed as "materials." Existing technologies only allow for direct material spreading via manual labor and conveyor belts. While it's possible to transport materials to a designated location via fixed pipes and then spread them manually or with other machinery, the inconvenience of pipe extension makes it unsuitable for large-scale, localized farming. Therefore, at most, materials are transported to a fixed location via fixed pipes and then further processed with other equipment. This method involves numerous pieces of equipment, and the materials are exposed unnecessarily for a period of time and space. The entire workshop environment has a strong odor and poor cleanliness. Furthermore, the material distribution at fixed points is uneven, often resulting in clumps of material, making it unsuitable for direct insect farming and requiring additional assistance to spread the material evenly.

[0047] This application utilizes the coordination of the winding tube trolley and the unloading tube to ensure that the feeding tube is always taut, thereby facilitating the material transport and management within the feeding tube. This ensures that the feed or insect feed mixture transported through the feeding tube is delivered smoothly and controllably to its intended location, completely avoiding unnecessary exposure in space and time during the transport process. Specifically, when the unloading tube moves along guide rail two under the drive of motor two, it pulls the feeding tube. Because the feeding tube is wound twice in opposite directions by the guide tube trolley and the winding tube trolley, and the guide tube trolley remains stationary while the feeding tube is fixed at the feed inlet end of the breeding equipment, the pulling of the feeding tube simultaneously pulls the winding tube trolley to move in the opposite direction relative to the unloading tube along guide rail one. This increases the distance between the guide tube trolley and the unloading tube, and shortens the distance between the guide tube trolley and the winding tube trolley, ensuring that the portion of the feeding tube within the insect breeding equipment is always orderly taut. This guarantees effective and efficient material distribution, and the equipment is simple with a small overall structure.

[0048] The feeding end of the feeding pipe can be fixed on the frame used to install the guide rail, while the discharging end of the feeding pipe is fixed on the unloading car. This ensures that the feeding pipe is always in a taut state only during the reciprocating motion of the unloading car and the winding car. Only the length of the feeding pipe changes in each section from the feeding end to the winding car, from the winding car to the guide car, and from the guide car to the unloading car, while the total length remains unchanged.

[0049] Existing material feeding methods can only involve fixed-point feeding, resulting in piled-up materials with poor uniformity, requiring additional equipment for spreading; or loading materials onto a mobile device before moving to feed them, and then returning to the initial position to reload and continue feeding after the material on the mobile device is used up. This method cannot provide continuous material supply to the feeding device, resulting in low feeding efficiency. This application enables continuous material supply to the feeding pipe, meaning the feeding vehicle does not need to return to the initial position to load and then feed, allowing for continuous feeding. This significantly improves feeding efficiency, completely changing the existing problem of unsustainable feeding, and also improves the sealing of enclosed aquaculture equipment, enabling feeding and feeding within a completely sealed environment.

[0050] Example 2:

[0051] The difference from the above embodiments is that the application also includes a support rail 7 for supporting the feeding pipe, located beside the second guide rail, and the support rail is arranged parallel to the second guide rail. The feeding pipe has a certain strength to ensure that it can maintain its cylindrical shape regardless of whether the pipe is full of material, but it also has the characteristic of being flexible and changing direction. For example, PVC transparent steel wire hose, or other pipes that can meet the requirements of this application can be used in this application. When the feeding pipe between the guide carriage and the unloading carriage is too long, the feeding pipe may fall onto the breeding board, especially when the feeding pipe is full of material, due to its weight, it is more likely to fall. This situation will affect the normal and effective lifting of the feeding pipe for work, and may also cause the material already placed on the breeding board to be dragged and displaced. Therefore, a support rail is set beside the second guide rail, so that the feeding pipe can be supported by the support rail no matter how long it is. The support rail can play a good guiding role, preventing the feeding pipe from falling or deviating, and making it more convenient and smooth for the unloading carriage or the pipe winding carriage to pull the feeding pipe.

[0052] Specifically, an outlet 71 is provided on the upper part of one side of the support rail, and a discharge bend 21 is provided at the front end of the feeding pipe. The discharge bend is located on the feeding trolley, with its inner end connected to the feeding pipe and its outer end extending to the outside of the support rail through the outlet. The lower edge of the outlet is a side stop 72 that extends beyond the track surface of the support rail. The material is not discharged directly from the discharge end of the feeding pipe, but is discharged through the discharge bend connected to the discharge end. The discharge bend leads the material from the feeding pipe to the side of the support rail for further discharge, thus ensuring that all the material can be smoothly and directly discharged onto the breeding plate without falling onto the support rail. This ensures that the equipment is not easily damaged, the discharge is continuous and efficient, and the support rail is clean and can be used effectively for a long time.

[0053] The feed pipe can slide on the support rail, and the discharge bend moves at the outlet. The side baffle can restrict the feed pipe on the support rail to prevent it from escaping, thus ensuring that the feed pipe can move smoothly on the support rail and that the material can be discharged onto the breeding board without obstruction. The diameter of the feed pipe can be greater than, less than, or equal to the height of the outlet, with the preferred choice being that the diameter of the feed pipe is greater than the height of the outlet.

[0054] Even better, multiple idlers 73 are arranged sequentially along the length of the track surface of the feed guide rail, with the axis of the idlers perpendicular to the length of the feed guide rail, thus making the feeding pipe more smoothly pulled. Similarly, multiple idlers can also be installed at the lower part of the guide rail corresponding to the positions along the path of the feeding pipe to ensure the stability of the feeding pipe. Thus, idlers are used to catch any falling objects that may affect the aquaculture equipment, resulting in good equipment stability, less susceptibility to failure, and no need for material rework. The feed guide rail can be suspended from the aquaculture equipment by multiple sequentially arranged hooks 74, and the feed guide rail is then arranged inside the hooks. One side of the hook is used for external connection, and the other side can extend beyond the track surface as a side stop. This structure facilitates the installation, disassembly, and maintenance of the feed guide rail.

[0055] Additionally, the outer end of the feeding bend is connected to a discharge mechanism 9. After the feeding bend leads the material to the material support rail area, it can also be used in conjunction with some discharge mechanisms for feeding.

[0056] Example 3:

[0057] The difference from the above embodiments is that the specific discharge mechanism 9 can be a discharge pipe 91 with multiple discharge ports connected to the discharge bend, or multiple discharge pipes connected to the discharge bend. In this way, the material fed into the discharge bend can be evenly distributed onto the breeding board through multiple discharge ports. At the same time as distributing the material, the material is evenly distributed on the breeding board, avoiding the need for other equipment or manual spreading, thereby achieving high efficiency and energy saving.

[0058] Of course, the feed bend can also be connected to an isobaric distribution tank and multiple distribution pipes, so that the material can be evenly distributed and fed through the distribution pipes.

[0059] Example 4:

[0060] The difference from the above embodiments is that the discharge mechanism may also include a lead screw 92 mounted on a feeding trolley, a movable slider 93 mounted on the lead screw, and a feeding tube 94 connecting the movable slider and the feeding bend. The lead screw is arranged in the transverse direction of the aquaculture plate. The feeding bend delivers the material to the feeding tube, and then the discharge port of the feeding tube moves laterally back and forth on the lead screw along with the movable slider, thereby distributing the material onto the aquaculture plate, thus achieving a controllable and uniform material distribution effect, that is, achieving the effect of precise material distribution through the reciprocating motion of a single discharge port.

[0061] Example 5:

[0062] The difference from the above embodiments is that the guide tube is provided with at least one rotary channel 31, the feeding tube is rotated through the rotary channel, and at least one guide wheel 031 is provided on each side of the rotary channel and / or the rotary channel is a rotary turning tube.

[0063] Similarly, the tube winding vehicle is equipped with at least one rotary channel 31, through which the feeding tube changes direction and rotates. At least one guide wheel 031 is provided on each side of the rotary channel and / or the rotary channel is a turning tube 032.

[0064] The rotary channel of this application can be formed by clamping guide wheels or by a fixed rotary pipe adapted to the feeding pipe. The rotary channel formed by clamping guide wheels limits both sides of the feeding pipe, thereby ensuring that the feeding pipe is not easily loosened or displaced when the equipment is stopped, malfunctions, or under maintenance, making it convenient for staff to adjust and maintain the equipment.

[0065] Even better, since the feed pipe is generally not too small in diameter, for example, an 8-18 cm feed pipe has a large diameter and a certain strength, the bending radius corresponding to the rotation channel should not be too small. Therefore, when using guide wheels, three guide wheels can be set up on the inner side of the feed pipe with staggered upper, middle and lower positions, or multiple rows of guide wheels can be set up along the bending arc. This allows the small guide wheels to be used at multiple points to increase the bending diameter of the feed pipe at the rotation position, while also providing support for the feed pipe at multiple points on the same side, ensuring that the feed pipe changes direction smoothly when rotating.

[0066] Of course, multiple guide tubes can be installed on the turnaround pipe to reduce friction between the feed pipe and the turnaround pipe, improving the smoothness of the feed pipe's movement. Since the feed pipe used is generally a non-smooth pipe with a corrugated outer surface, when using a turnaround pipe, the two ends of the turnaround pipe can be designed as gradually widening arc-shaped flared openings to facilitate the introduction of the feed pipe. Rollers can also be installed on the inner wall of the turnaround pipe to improve the smoothness of the feed pipe's sliding. The turnaround channel can also be an arc-shaped guide plate with an open outer side, and the cross-section of the arc-shaped guide plate is arc-shaped.

[0067] It is evident that the pipe winding car and the guide tube car can be the same type of car arranged in reverse, except that the guide tube car is fixed on the parking frame, while the pipe winding car is movable. Specifically, the guide tube car can be fixedly installed on the outside of the parking frame, so as not to affect the parking of the unloading car on the parking frame. Of course, the guide tube car can also be installed inside the parking frame, as long as it does not interfere with the unloading car.

[0068] In the breeding process, both feed and insects need to be evenly distributed on the breeding board. Because insects are active, a large quantity of pure insects cannot be directly laid through pipes. In this application, insects and feed are mixed in a specific ratio to form an insect-feed mixture, which can be transported through pipes. This ensures both the activity of the insects and the piped transport of them. In this application, the insect-feed mixture and feed are collectively referred to as materials. Since the final breeding ratio involves a large amount of feed and a relatively small amount of insects, to ensure the activity of the insects during mixing and transport, it is not possible to directly mix the insects and feed in the final reasonable ratio before laying them on the breeding board. Instead, the insects must be mixed with an appropriate amount of feed, and then the mixture is transported through a feeding pipe. Therefore, when laying materials, it may be for laying the insect-feed mixture or for laying the main material. Therefore, a rotary channel can be set on the pipe-winding cart and the guide cart, and the feed and insect-feed mixture can be transported sequentially through the feeding pipe. Alternatively, two rotary channels can be set side-by-side on the pipe-winding cart and the guide cart, allowing for simultaneous feeding of the insect-feed mixture and the main material, greatly improving the efficiency of material laying.

[0069] The guide wheel includes at least one rotating guide wheel 311 located inside the feeding pipe and multiple anti-deviation guide wheels 312 located on the outer side. A rotation channel is formed between the rotating guide wheel and the anti-deviation guide wheels, and at least one anti-deviation guide wheel is provided above and below the rotating guide wheel. When the feeding pipe is filled with material, its weight is not light. Using multiple anti-deviation guide wheels can better guide the feeding pipe, preventing it from derailing due to excessive weight or other reasons during rotation, thus ensuring efficient operation of the feeding pipe.

[0070] Alternatively, the slewing guide wheel and the anti-deviation guide wheel can be matched one-to-one to form a set of guide wheels. Then, the slewing channel includes at least three sets of guide wheels: upper, middle, and lower. The three sets of guide wheels are staggered to form a slewing channel that protrudes outward from the center.

[0071] Example 6:

[0072] The difference from the above embodiments lies in that the drag chain material conveying device for insect farming includes multiple layers of guide rails arranged vertically, and also includes a lifting component 51 for lifting and lowering the feeding trolley to connect with the guide rails of each layer. Each layer of the farming board can have a corresponding guide rail 2 above it. Thus, the lifting component allows one feeding trolley to be shared by multiple farming boards. Specifically, the lifting component raises or lowers the feeding trolley to the guide rail 2 of the corresponding layer, and then the drive motor 2 is activated to move the feeding trolley along the guide rail 2 of that layer, thereby dragging the discharge end of the feeding pipe to move on that layer to supply material.

[0073] Further refinement of the lifting assembly may include a lifting and braking component 511 and a support component 512 mounted on the lifting and braking component for supporting or suspending the unloading trolley. The support component has a short rail 513 that mates with the second guide rail. The unloading trolley is connected to the short rail and the second guide rail via rollers driven by the second drive motor 11. The support component only needs to be able to support or suspend the unloading trolley while ensuring that the unloading trolley can detach from the support component and move towards the breeding board. The short rail can be fixed to the support component. When the unloading trolley is on the parking frame, it cooperates with the short rail through rollers. Both the short rail and the second guide rail can be selected as rails with inner grooves that have side openings. The rollers drive the unloading trolley within the inner grooves. Alternatively, other structures such as guide rails and sliders can be used, combined with the drive motor 11 to guide the unloading trolley.

[0074] Example 7:

[0075] The difference from the above embodiments is that the bottom of the feeding car is also provided with a material leveling component 501. The material leveling component includes a material leveling shaft 5011 arranged axially perpendicular to the length direction of the guide rail and material feeding plates 5012 arranged sequentially on the material leveling shaft; or the material leveling component is a plurality of plowshares 502 arranged sequentially, with the plowshares gradually narrowing from back to front.

[0076] For insect farming, a moderately varied thickness of the material, while maintaining overall uniformity, can actually improve efficiency. This is because it increases the surface area of ​​the material, thereby increasing its contact with air and expanding the feeding area for insects, ultimately increasing the number of insects raised. Furthermore, insects are naturally gregarious; uniformity ensures that the rearing board fully utilizes the rearing surface, guaranteeing a higher total number of insects raised per unit time. Moderately varied composting also provides a more suitable growth environment, promoting better growth rates for insects. Therefore, for the material distribution component, it's not necessary to completely flatten the material; simply spreading it out evenly to achieve a uniform overall effect with some variation is sufficient.

[0077] This application, by installing a material-leveling component at the bottom of the feeding vehicle, can further disperse and evenly distribute materials from various feeding methods, such as multi-path feeding and lateral reciprocating feeding, making the materials better meet the needs of aquaculture. Furthermore, the main material-leveling work can be performed by the material-leveling component, thereby reducing the number of discharge ports, lowering the feeding height, and allowing for adjustable material-leveling speed. At least one material-leveling plate or plowshare is installed behind each discharge port to ensure that the material in the main material pile's discharge path is evenly dispersed.

[0078] The material-distributing component can be a plowshare, with a shape that gradually narrows from back to front and from bottom to top, thus loosening and distributing the material to both sides as the feeding trolley moves forward, achieving a uniform material distribution. Alternatively, it can be a shaft-driven rotating material-distributing plate, which picks up and disperses the material falling from the outlet. The material-distributing plate can be multiple inclined plates tilted to both sides, a conical plate thicker at the base and thinner at the outer end, or an arc-shaped plate with a wavy shape from the base outwards. Multiple material-distributing plates can be arranged along the circumference of a bushing, which is fitted onto the shaft. As the shaft rotates, the material-distributing plates drive the material distribution.

[0079] Example 8:

[0080] The difference from the above embodiments is that the drag chain material conveying device for insect farming also includes a steel wire rope 8 arranged parallel to the feeding pipe along its winding trajectory. The steel wire rope is also wound around the winding trolley and the guide trolley, with one end fixed to the unloading trolley and the other end fixed to the feed end of the feeding pipe. Since the feeding pipe needs a certain degree of rigidity and ductility to bend and change direction, a corrugated pipe needs to be selected. The length of the corrugated pipe can be long or short. If the tension of the feeding pipe is used to pull the winding trolley or the unloading trolley, the unloading trolley may not be able to reach the entire area of ​​the farming board that needs to be covered with material. In particular, when the winding trolley moves along the guide rail under the drive of the drive motor to pull the unloading trolley, when the winding trolley reaches its own end, the feeding pipe may be stretched and extended, causing the unloading trolley to not reach the designated end, thus creating unnecessary blind spots in feeding. Therefore, a steel wire rope is installed beside the feeding pipe along its trajectory to constrain the movement of the pipe-winding trolley and the unloading trolley. This ensures that the unloading trolley can smoothly pass over the designated unloading area, facilitating operation and improving the stability and reliability of the equipment. The feed end of the feeding pipe can be fixed to the frame of the aquaculture equipment, and the corresponding end of the steel wire rope can be fixed beside the feed end of the feeding pipe. A dedicated turning channel can be provided on the pipe-winding trolley and the guide trolley to ensure the stability of the steel wire rope and its synchronization with the trajectory of the pipe-winding trolley. Furthermore, the above design does not necessarily require a steel wire rope; any rope that meets the design requirements of this application can be used.

[0081] Example 9:

[0082] The difference from the above embodiments is that the tube-winding carriage can move along the guide rail under the drive of the first drive motor. The tube-winding carriage can have drive wheels 41 driven by the first drive motor on both sides cooperating with the guide rail. Of course, it can also be as follows: Figure 17The illustrated tube-winding cart has a structure on one side driven by a drive motor, consisting of a gear 43a and a rack 43b that meshes with the gear. On the other side, it has a structure where a guide rail meshes with a drive wheel. The gear and rack have good meshing, resulting in relatively stable operation, so the other side only requires auxiliary interaction between the guide rail and the drive wheel. The rack can be mounted below the guide rail. Alternatively, it can use a gear and chain combination, where the driving force comes from an external drive motor pulling the chain, which in turn drives the gear meshing with the chain, thus moving the cart.

[0083] Furthermore, the rack in this application is a curved, wavy rack, such as... Figure 17 As shown, the gear includes a shaft 43-1, limiting guide plates 43-2 located at both ends of the shaft, and a gear rack 43-3 connected between the two limiting guide plates and evenly distributed around the shaft. The width between the two limiting guide plates is greater than the width of the gear rack, and the two limiting guide plates respectively guide the ends of the gear rack. The gear rack is a cylindrical bar that can be embedded in the tooth groove of the gear rack. The gear rack can be close to the shaft or have a gap, and adjacent gear racks do not contact each other. Through the cooperation of the wavy rack with the aforementioned specific gear rack, and with the meshing range limited to the guide groove formed by the cooperation of the limiting guide plates and the shaft, a relatively smooth and stable meshing can be achieved, with less jerking. The transmission is quieter and more stable, the cart travels smoothly with less vibration, and it is less likely to derail, greatly improving the stability of the equipment. Furthermore, a driven wheel 42 can be installed above the guide rail at the position corresponding to the gear, which cooperates with the gear to clamp the guide rail. In addition, a set of driven wheels can be connected to one side of the driven wheel by a bridge. This set of driven wheels consists of two driven wheels located at the top of the guide rail and at the bottom of the rack. The driven wheel 42-1 located at the top is sleeved on the guide rail and adapted to the guide rail, while the driven wheel 42-2 located at the bottom is sleeved on the rack and adapted to the guide rail. This can further and more effectively prevent derailment, improve stability, and increase the strength of the equipment.

[0084] A sealed insect breeding equipment includes the aforementioned drag chain material conveying device for insect breeding, and further includes a main frame 01, shelves 02, and breeding plates 03. The main frame has one or more shelves arranged vertically at intervals. The breeding plates are placed on the shelves. A parking rack 1 is located at the end of the main frame. A guide rail 2 is provided above each shelf on the main frame, and the guide rail 2 is arranged along the length of the breeding plate. The guide rail 2 is provided on the main frame, the parking rack, and / or the shelves.

[0085] The feeding trolley can be installed at the top of the aquaculture equipment, with the unloading trolley positioned lower than it, meaning the feeding pipe extends from the top of the aquaculture equipment. Alternatively, the feeding trolley can be installed at the bottom of the aquaculture equipment, with the feeding pipe extending from the bottom and the unloading trolley positioned higher than it. Ideally, the feeding trolley should be installed at the top of the aquaculture equipment. Rollers 021 can also be installed on the end crossbars of the shelf corresponding to the parking rack. When the unloading trolley pulls the feeding pipe to feed the aquaculture plate, the feeding pipe may abut against the crossbars of the shelf; the rollers help ensure smooth feeding.

[0086] The aquaculture equipment also includes a lifting component 04 located on the outside of the aquaculture board. Each shelf has two horizontally spliced ​​aquaculture boards, which together form a aquaculture unit. The splicing area is an openable discharge channel 032. One or more aquaculture units are surrounded by a sealing material forming an aquaculture cavity 07, which is installed horizontally along the aquaculture unit. When the outer side of the aquaculture board is tilted and lifted by the lifting component, the discharge channel between the spliced ​​aquaculture boards opens to collect adult insects and insect waste. A suitable vibrator can then be installed directly or indirectly on the aquaculture board to assist in the final collection of materials after aquaculture. The lifting component can act directly on the aquaculture board, or it can simultaneously lift multiple aquaculture boards using a single lifting component via a connecting rod 05 or similar structure. The aquaculture board is connected to the shelf via a horizontally set slot and a hinge shaft within the slot, allowing the inner end of the aquaculture board to move outward when the outer side is lifted, thus opening the discharge channel. Two aquaculture plates are spliced ​​together along their width and can be stretched out along the same width to create a discharge channel at the original splice seam, allowing for material collection and discharge. This enables localized material discharge, rather than long-distance, time-consuming discharge, thus shortening discharge time and improving discharge flow. Furthermore, the discharge channel is not formed by moving the aquaculture plates outwards from the main frame, but rather by tilting the aquaculture plates using a lifting component, creating a gap that serves as the discharge channel. This not only facilitates material discharge by utilizing the tilted aquaculture plates but also creates a collection channel, eliminating the need for additional expansion of the main frame and enhancing the overall integrity of the equipment. Localized discharge also effectively reduces the adhesion and accumulation of remaining material on the aquaculture plates during discharge and accelerates the discharge speed. A conveyor belt 08 can be installed below the bottom aquaculture plate to collect recycled materials such as insects and insect sand shaken down from the discharge channel.

[0087] The sealing material completely encloses the main frame and parking frame to form the breeding chamber 07. The drag chain material conveyor for insect breeding is also enclosed within, creating a sealed environment. Air inlets and outlets are only needed at both ends of the breeding chamber. These inlets and outlets can also be connected to air control, humidity control, and temperature control devices, allowing for controlled artificial intervention in the temperature and humidity of the entire breeding environment. This significantly improves insect breeding efficiency and increases the adult insect rate. For the material conveying device, only the inlet end of the feeding pipe needs to be inserted into the sealing material, ensuring that the material is not exposed between the feeding and breeding plates. This guarantees a clean environment with minimal air pollution and avoids unnecessary exposure of the material in time and space.
