Description

Technical Field

[0001] This invention relates to the field of aquaculture, and in particular to a three-dimensional aquaculture system. Background Technology

[0002] With rising living standards and increasing demand for protein and traditional Chinese medicine, coupled with the depletion of fishery resources and a growing emphasis on the environmentally friendly resource utilization of organic waste from food processing, catering, agriculture, and landscaping, the demand for raising small insects such as fly larvae, mealworms, black soldier flies, grubs, and ground beetles, as well as earthworms and snails—"micro-livestock"—is increasing. However, with urbanization, the area available for raising these animals is shrinking. To reduce the space required for aquaculture, multi-layered, three-dimensional farming methods are often used to raise a larger number of animals within the same area. Existing three-dimensional "micro-livestock" farming units typically include multi-layered frames with trays, conveyor belts, or stacked / suspended multi-layered boxes. However, the existing structures often feature horizontally positioned trays, conveyor belts, or boxes that require movement or flipping for feeding, unloading, or cleaning. This makes adjustments difficult, reduces adjustability, and makes cleaning time-consuming and labor-intensive.

[0003] Therefore, a more convenient and efficient three-dimensional aquaculture system is needed to solve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this application discloses a three-dimensional aquaculture system, comprising a fixed aquaculture body, a feeding unit, and a three-dimensional multi-layer feeding device. The feeding device is movably located next to the aquaculture body. The feeding unit is equipped with a feeding bin and a movable internal collection device, such that the collection device is movably located within the feeding bin for collecting materials.

[0005] The aquaculture body includes stacked aquaculture pits, a support frame, and a discharge channel in the middle. The aquaculture pits are arranged in two rows that are symmetrical from left to right and the two rows are inclined downwards towards the discharge channel. The discharge end of the aquaculture pits is provided with a discharge side door.

[0006] The upper end of the unloading channel is connected by the support frame, but the lower end is not connected. The receiving unit is set at the bottom of the breeding body. The upper opening of the receiving bin and the unloading channel form a "U" shaped space, so that the material falling from the breeding trough can directly enter the receiving bin and be collected by the collecting device.

[0007] The feeding device is provided with a number of storage troughs corresponding to the number of breeding troughs, so that the material in the storage troughs can be put into the corresponding breeding troughs. The storage troughs are inclined and the outlet end of the storage troughs is provided with a feeding side door.

[0008] Furthermore, the collecting device is a push-pull railcar, the upper opening area of ​​which is larger than the lower outlet area of ​​the unloading channel, and the upper opening of the push-pull railcar extends outward from the bottom of the aquaculture body.

[0009] Furthermore, the push-pull railcar is equipped with a buffer frame that extends upward into the unloading channel;

[0010] The buffer frame is equipped with staggered funnel plates and anti-bucket plates. The buffer frame is vertically connected to one end of the bucket of the push-pull railcar, and the other end extends into the unloading channel and is lower than the height of the unloading channel.

[0011] Furthermore, the feeding device is a feeding cart with multiple layers of three-dimensional storage troughs stacked together. The bottom plate of the storage trough is equipped with a vibration device to enhance the feeding intensity. The feeding cart includes a vertically arranged feeding channel and a base set at the bottom.

[0012] One end of the feeding channel is connected to the upper end of the storage trough, and the other end is provided with a number of diversion plates corresponding to the storage trough. The diversion plates are inclined and their lower ends are all higher than the upper end of the storage trough, so that the feeding can be fed layer by layer from top to bottom along the diversion plates. The bottom end of the feeding channel is provided with a residual material trough.

[0013] It also includes a scraping device, which includes a scraping part and a support base that can be limited and slidable. The scraping part is fixedly connected to one end of the support base, and the other end of the scraping part extends into each of the storage troughs and is close to the bottom plate of the storage trough. The support base can be laterally limited and slidable to drive the scraping part to perform lateral reciprocating motion along the bottom end of the storage trough to scrape the stored material.

[0014] Furthermore, the base is equipped with a water tank and a water pump, and each of the storage troughs is equipped with a water supply structure that communicates with the water tank;

[0015] Furthermore, the feeding side door is configured as a single-control door or a linkage door, and the feeding side door is equipped with a vibration mechanism so that when the feeding side door is opened, it can enhance the vibration and drop of the material in the storage trough.

[0016] Furthermore, the support frame comprises several horizontal supports and at least eight vertical supports. The placement platform of the aquaculture trough is formed by a base plate overlapping the horizontally adjacent and staggered horizontal supports, so that the base plate overlaps the horizontal supports to form an inclined surface. The base plate is provided with a vibration device to enhance the unloading strength.

[0017] Furthermore, the horizontal support is an angle steel, and obtuse angle steel and acute angle steel are respectively provided on the horizontally adjacent horizontal supports. The height of the obtuse angle steel is greater than that of the acute angle steel, so that the base plate can fit and overlap on the staggered horizontal supports.

[0018] Furthermore, the discharge side door is a single-controlled or jointly-controlled sliding door, and the discharge side door includes an extension plate and an outer sealing plate;

[0019] The extension plate is formed by a downward extension of the angle steel, and the outer sealing plate is arranged at the lower end of the extension plate and cooperates with the extension plate to open and close by moving up and down.

[0020] Furthermore, at least two vertical rods are further included. The vertical rods are arranged on the side of the discharge channel close to the discharge side door. The height of the vertical rods is consistent with the length of the discharge channel and is fixed after passing through the angle steel from top to bottom. The vertical rods are arranged between the discharge side door and the discharge channel so that the vertical rods provide lateral stress for the discharge side door and support and cooperate with the opening and closing of the discharge side door;

[0021] One end of the feeding side door is connected to the storage cavity, and at least two of the vertical rods are arranged at the other end of the feeding side door so that the vertical rods provide lateral stress for the feeding side door and support and cooperate with the opening and closing of the feeding side door.

[0022] The three-dimensional breeding system provided by the present application has at least the following beneficial effects:

[0023] 1. The present application forms a breeding system for small insects such as fly maggots, yellow mealworms, black soldier flies, etc. and other "micro livestock" such as earthworms, grubs, and snails through a breeding body, a material collection unit, and a movable feeding device. The breeding cavities are inclined inward, and discharging or excrement dropping is realized by gravity and then collected by the material collection bin. The breeding cavities can be discharged or cleaned without being pulled out or moved, saving labor; the horizontal brackets or angle steels with different heights are matched so that the bottom plate support structure can pull each other, and the bottom plates are lapped to play a stable bearing role. The discharging or cleaning space inside the support frame forms a "convex"-shaped space. The upper part of the support frame is connected to the lower part through a right-angle design to form a support frame similar to a tent with a suspended middle part, which can not only prevent the overall deformation of the frame but also has a larger space for discharging or excrement dropping; at the same time, the feeding side door and the discharge side door are convenient for accurate feeding and discharging, the vertical rods can reinforce and support the opening or closing of the discharge side door or the feeding side door, and the hollow design of the discharge channel is also convenient for air circulation and temperature control, which can better improve the user experience;

[0024] 2. The feed channel of the feeding equipment in this application has a diversion plate and a storage trough that are inclined, which facilitates the batch injection of feed, water and other materials under the action of gravity only, saving manpower and making it easy to realize intelligent breeding. The doors of each outlet of the storage trough or the breeding trough of the breeding body can be set as a linkage structure, which can realize three-dimensional multi-layer simultaneous feeding or unloading. By setting a scraping device, it is easy to scrape the material in the storage trough, which is conducive to the falling of the material and thus completing the feeding or unloading. In addition, the water tank set in the base can stabilize the center of gravity of the feeding equipment and provide a water source.

[0025] 3. This application achieves integrated feeding and harvesting production line operation by using a fixed breeding body in conjunction with a movable collection device and feeding equipment set in the bottom receiving bin, which makes it possible to feed and unload multiple breeding bodies, and facilitates systematic intelligent breeding.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0038] Please refer to Figure 1-8As shown in the figure, a three-dimensional breeding system includes a fixed breeding body 1, a material collection unit arranged at the bottom, and a three-dimensional multi-layer feeding device 4 arranged beside the breeding body 1. The breeding body 1 includes stacked and symmetrically arranged breeding cavities 11, a support frame 2, and a discharge channel 3 arranged in the middle. The breeding cavities 11 are arranged in two rows symmetrically left and right, and the two rows of breeding cavities 11 face downward relative to the discharge channel 3, which is convenient for discharging or cleaning and collecting excrement. Preferably, each row of breeding cavities 11 includes at least two, and the breeding cavities 11 are stacked up and down on the support frame 2 to form a multi-layer three-dimensional breeding body 1. The material collection unit includes a material collection bin 5 and a mobile internal collection device 6, and the collection device 6 is movably arranged in the material collection bin 5 for collecting materials. For the purpose of discharging or allowing dirt to fall by itself only relying on gravity, the breeding cavities 11 are inclined, preferably at an inclination angle of 35° to 65°, and the breeding cavities 11 on the same layer all face the discharge channel 3 and are symmetrically inclined downward, so that the discharged materials or dirt in the breeding cavities 11 can be concentrated and dropped along the discharge channel 3 by their own gravity for collection, without the need to extract or move the breeding cavities 11 to collect materials.

[0039] On this basis, a feeding device 4 for feeding materials such as feed and water is arranged beside the breeding body 1. The feeding device 4 is provided with storage cavities 41 corresponding to the number of breeding cavities 11, so that the materials in the storage cavities 41 can be put into the corresponding breeding cavities 11. At the same time, the storage cavities 41 are inclined to feed materials by gravity, and a feeding side door 411 is arranged at the outlet end of the storage cavity 41 to control the feeding amount. Therefore, through the cooperation of the breeding body 1, the movable collection device 6 and the feeding device 4, an integrated production and collection pipeline operation is realized, which is convenient for systematic intelligent breeding.

[0040] Among them, the breeding cavity 11 also includes a discharge side door 13 arranged at one end close to the discharge channel 3, which is used to control the discharge or cleaning and collection of excrement. Optionally, the discharge side door 13 is equipped with a vibration device to better vibrate and discharge materials. In addition, for the purpose of the overall structural stability of the frame, the upper end of the discharge channel 3 or the top of the frame is connected by the support frame 2 to form a frame top, and the lower end is not connected. It forms a support frame 2 similar to a tent shape with a suspended middle through a right-angle design, which can not only prevent the overall deformation of the frame, but also has a larger space for discharged materials or excrement to fall, and then a material collection bin 5 is formed at the bottom of the breeding equipment. The upper opening of the material collection bin 5 and the discharge channel 3 form a "convex" - shaped space, so that the discharged materials or waste of the breeding body 1 can directly enter the material collection bin 5 after falling, and at the same time, the overall outer surface is beautiful and concise. Of course, in order to make the frame structure more stable, the bottom feet of the support frame 2 can also be optionally connected by a cross support 21 to make the overall breeding body 1 more stable.

[0041] Based on the above technical solution, the collection device 6 preferably adopts a push-pull railcar 6, which realizes the pushing and pulling of the car body through the rail and pulley structure, which facilitates unloading or cleaning up the accumulated excrement and waste. The upper opening area of ​​the push-pull railcar 6 is larger than the lower outlet area of ​​the unloading channel 3. The upper opening of the push-pull railcar 6 extends outward to the bottom of the breeding equipment. In this way, it is ensured that the fallen unloaded material or excrement will not fall out of the car body's collection range, which facilitates material collection and cleaning.

[0042] To cushion the impact of falling materials, a buffer frame 7 is installed on the push-pull railcar 6. The buffer frame 7 extends upward into the unloading channel 3. The buffer frame 7 reduces the impact of falling collected materials by blocking and buffering.

[0043] Specifically, the buffer frame 7 is preferably equipped with staggered funnel plates 71 and anti-flush plates 72. When unloading or excrement passes through them, the impact intensity can be better reduced, which can reduce the risk of direct fall injury to the cultured animals in the troughs of the high-level aquaculture body 1. At the same time, the buffer frame 7 is set to be vertically connected to one end of the hopper of the push-pull railcar 6, and its other end extends into the unloading channel 3 but is lower than the height of the unloading channel 3, so that the top layer of waste falling can also be buffered.

[0044] Based on this, the preferred feeding device 4 is a movable feeding cart 4. The feeding cart 4 is designed with a multi-layered three-dimensional structure to facilitate precise layered feeding. Specifically, the feeding cart 4 is equipped with storage troughs 41 that correspond one-to-one with the breeding troughs 11. It also includes a feeding channel 42 and a base 45. The feeding channel 42 is vertically arranged at one end of the storage trough 41, and the base 45 is located at the bottom of the feeding cart 4. At the same time, the storage troughs 41 are inclined. One end of the feeding channel 42 is connected to the higher end of the storage trough 41, and the other end is equipped with a number of diversion plates 43 corresponding to the number of storage troughs 41. The diversion plates 43 are optional. The feed channel 42 is inclined, with its lower end higher than the top of the storage trough 41. When feed enters the feed channel 42, it is blocked by the diversion plate 43 and guided to slide down sequentially to each layer of the storage trough 41. The feed then slides into the aquaculture body 1 through the inclined storage trough 41 for feeding. Feed and other substrates are automatically and quantitatively distributed to each three-dimensional storage trough 41 by gravity, without external force, and simultaneously quantitatively added to each of the three-dimensional multi-layered aquaculture body 1 troughs. This achieves the unloading and collection of the aquaculture objects and culture substrate in each three-dimensional aquaculture trough 11, realizing the effect of "simultaneous inflow, simultaneous feeding, and simultaneous outflow". The bottom of the feed channel 42 is equipped with a feed trough 44 to collect excess feed that has fallen. Specifically, the diversion plate 43 can be optionally configured in a ladder-like shape, with a stepped middle section and two sides fixed to two vertical plates. Preferably, the diversion plate 43 and the bottom plate of the storage trough 41 are staggered. In this way, the bottom plates of each diversion plate 43 and the corresponding storage trough 41 are staggered. The feed and other substrates can be filled into each storage trough 41 from top to bottom through the feeding channel 42 at the top of the feeding vehicle with a buffer. Then, they enter the breeding trough 11 through the feeding side door 411 for breeding and are unloaded through the unloading side door 13. In this way, feeding, breeding and unloading are realized in an assembly line operation. There is no need to move the fixed breeding frame and breeding trough 11. The movable feeding vehicle 4 and the movable push-pull rail vehicle 6 (unloading vehicle) can be connected to multiple breeding frames or breeding bodies 1, reducing labor intensity and investment.

[0045] The storage trough 41 is equipped with a feeding side door 411 at one of its lower ends. The feeding side door 411 can be a single-control door or a linkage door. Similar to each breeding trough 11, the feeding side door 411 at the discharge port of each storage trough 41 can be optionally set as a linkage switch, i.e., a synchronous switch, so as to realize three-dimensional multi-layer simultaneous feeding or discharging.

[0046] Based on this, the feeding cart 4 may optionally be equipped with a scraping device 46, which is used to scrape the material at the bottom of the storage trough 41, making the material loose and easier to fall out of the storage trough 41. In an optional embodiment, such as Figure 1The scraping device 46 shown in Figure 3 includes a scraping part 461 and a support base 462 that can be limited and slidably connected. The support base 462 is slidably connected to the feeding cart 4. The scraping part 461 is fixedly connected to one end of the support base 462, and the other end of the scraping part 461 extends into each storage trough 41 and is close to the bottom plate of the storage trough 41. The support base 462 can be laterally limited and slidably driven to make the scraping part 461 move laterally reciprocating along the bottom end of the storage trough 41 to scrape the stored material. The scraping part 461 can be optionally a scraping roller or a scraping plate.

[0047] In addition, the base 45 located at the lowest end of the feeding cart 4 is preferably equipped with a water tank and a water pump. It can not only stabilize the center of gravity of the entire feeding cart 4, but also provide a water source for the storage troughs 41. At the same time, each storage trough 41 is equipped with a water supply structure connected to the water tank. Specifically, it may include water supply pipes and nozzles distributed in each storage trough 41.

[0048] In a preferred embodiment, the support frame 2 consists of several horizontal supports 21 and at least eight vertical supports 22. The platform for the aquaculture body 1 is formed by a base plate 12 overlapping the horizontally parallel and staggered horizontal supports 21, creating a stable inclined surface on the base plate 12, facilitating unloading or the falling of excrement. Thus, the feed inlet and discharge outlet of the aquaculture trough 11 of the aquaculture body 1 are positioned opposite each other, with the feed inlet higher than the discharge outlet, facilitating gravity-based feeding and unloading. Preferably, the base plate 12 is equipped with a vibration device (not shown in the figure) to enhance the unloading intensity; any existing technology capable of vibrating and shaking the material for unloading can be used for the vibration device.

[0049] Specifically, the horizontal supports 21 are preferably made of angle steel. Adjacent horizontal supports 21 are respectively set as obtuse angle steel 211 and acute angle steel 212. One of their extension plates 131 is vertically downward. Preferably, the other extension plate 131 extends in the opposite direction and the angles of the obtuse angle steel 211 and acute angle steel 212 are complementary. In this way, the base plate 12 placed on it can be stably erected. Among them, the height of the obtuse angle steel 211 is greater than that of the acute angle steel 212, that is, the obtuse angle steel 211 is at the higher position and the acute angle steel 212 is at the lower position. This allows the base plate 12 of the inclined breeding body 1 to fit and overlap well on the staggered horizontal supports 21, so that the entire inclined base plate 12 can remain flat and balanced in force.

[0050] In a preferred embodiment, the unloading channel 3 near the unloading side door 13 further includes at least two vertical rods 23. The height of the vertical rods 23 is the same as the length of the unloading channel 3, and they pass through the acute angle steel from top to bottom and are then fixed. The vertical rods 23 are positioned between the unloading side door 13 and the unloading channel 3, so that the vertical rods 23 provide lateral stress support for the unloading side door 13, that is, to provide support for the unloading side door 13 to prevent the material from deforming due to the pressure of gravity on the unloading side door 13. At the same time, they serve as the track for the unloading side door 13 to open and close vertically and cooperate to support the opening and closing function of the unloading side door 13. Optionally, the vertical rods 23 are welded to the acute angle steel after passing through a hole.

[0051] Similarly, the feeding side door 411 of the feeding device 4 is preferably provided with the aforementioned vertical rod 23 for support and cooperation. One end of the feeding side door 411 of the feeding device 4 is connected to the storage trough 41, and the other end of the feeding side door 411 is provided with at least two of the aforementioned vertical rods 23, so that the vertical rods 23 provide lateral stress for the feeding side door 411 and support and cooperate with the opening and closing of the feeding side door 411.

[0052] Specifically, the unloading side door 13 includes an extension plate 131 and an outer sealing plate 132. The unloading side door 13 is preferably a single-control or multi-control sliding door. The extension plate 131 is formed by a vertically downward extension of an acute-angle steel rod. The outer sealing plate 132 is located at the lower end of the extension plate 131 and moves up and down to cooperate with the extension plate 131 in opening and closing the unloading side door 13. Similarly, the feeding side door 411 can be structured similarly to the unloading side door 13. Both the feeding side door 411 and the unloading side door 13 can optionally be configured as a linkage switch, i.e., a synchronous switch, thus enabling simultaneous feeding or unloading of multiple layers in a three-dimensional manner.

[0053] In a preferred embodiment, the lowest end of the breeding body 1 is provided with an activity chamber 8. The activity chamber 8 is configured to be hinged to the top of the receiving bin 5 via a hinge shaft, so that the activity chamber 8 can be rotated around the hinge shaft. The unloading or excrement inside can also fall into the receiving bin 5 through the rotation and then enter the push-pull railcar 6 for collection and cleaning. This can make full use of the corner area of ​​the frame.

[0054] For ease of illustration, the left and right walls of the breeding trough 11, the storage trough 41, or the feeding channel 42 in the figure have been omitted. That is, the non-inlet / outlet surfaces of the breeding body and the feeding cart 4 or the feeding channel 42 can be optionally equipped with sheet metal, wooden boards, etc. as trough walls to prevent material leakage from the side.

[0055] The three-dimensional aquaculture system provided in this application has at least the following beneficial effects:

[0056] 1. This application forms a small livestock breeding system through a breeding body, a material collection unit, and a movable feeding device. The breeding trough is inclined inward, and卸料 and excrement fall into the collection bin by gravity and are then collected. The breeding trough can be emptied and cleaned without being pulled out, saving labor and facilitating intelligent breeding. The horizontally staggered cross brackets or angle steels cooperate with the support members to enable the bottom plate support structure to be mutually traction, and the bottom plates are lapped to play a stable bearing role. The space for卸料 and waste dropping and collection inside the support frame 2 forms a "convex" - shaped space. The upper part of the support frame is connected to the lower part through a right - angle design to form a support frame 2 similar to a tent shape with a suspended middle part, which can not only prevent the overall deformation of the frame but also have a larger space for卸料 and excrement dropping.

[0057] 2. The hollow design of the卸料 channel 3 in this application is conducive to air circulation and temperature regulation. The collection bin 5 and the push - pull rail car 6 are arranged at the bottom to facilitate material collection and excrement cleaning. At the same time, the卸料 side door 13 and the vertical rod 23 arranged in the middle space are beneficial for controlling卸料 and excrement dropping, and the vertical rod 23 can reinforce and support the opening and closing of the卸料 side door or the feeding side door.

[0058] 3. The diverter plate 43 and the storage trough 41 of the feeding channel 42 of the feeding truck 4 in this application are inclined, which is conducive to the batch - by - batch and quantity - by - quantity injection of feed, saving labor and being easy to realize intelligent breeding, providing the possibility for uniform feeding. The doors at the outlets of the storage trough 41 or the troughs of the breeding body 1 can be set as a linkage structure to achieve three - dimensional multi - layer simultaneous feeding or卸料. By setting a scraping device, it is convenient to scrape the materials in the storage trough, which is beneficial for the dropping of materials and thus completes feeding or卸料. In addition, the water tank arranged on the base 45 can stabilize the center of gravity of the feeding truck and provide water source at the same time.

[0059] 4. This application realizes the feeding and production - harvesting assembly - line operation through the fixed breeding body 1, the material collection unit arranged at the bottom, and the feeding device 4. The movable feeding truck 4 and the push - pull rail car 6 form an intelligent breeding system, mainly relying on gravity to simultaneously feed and harvest materials for multiple breeding bodies 1, facilitating systematic intelligent breeding.

[0060] The above are only the preferred embodiments of this application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of this application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of this application.
