Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to an improved multi-layer three-dimensional aquaculture device. Background Art

[0002] Existing three-dimensional aquaculture units for small insects such as maggots, mealworms, black soldier flies, white grubs and ground beetles, and "micro-livestock" such as earthworms and snails generally include multi-layer frames and trays, conveyor belts or stacked and suspended multi-layer boxes arranged thereon. However, in the structure of the existing aquaculture frames, the trays, conveyor belts or boxes need to be moved or flipped in order to feed, unload or clean, which is complex and time-consuming to operate, and not easy for intelligent assembly line operation. At the same time, the existing multi-layer three-dimensional aquaculture equipment does not have a buffer and collection structure during centralized unloading or it is an external structure (such as the patent application with the application number CN202410286363.X submitted by the applicant). There is no structure for collecting and protecting the aquaculture targets when the materials or aquaculture targets fall from a height, or the existing structure has limited effects. In addition, the load-bearing, compressive and anti-deformation capabilities of the bottom plate of the aquaculture cavity need to be improved.

[0041] Please refer to Figure 1-8As shown in the figure, an improved multi-layer three-dimensional breeding device includes a fixed breeding unit 1 and a material receiving bin 5. The breeding unit 1 includes stacked breeding cavities 11, a support frame 2, and a middle connecting member 31 disposed in the middle discharge channel 3. The breeding cavities 11 are arranged in two rows, symmetrically opposite to each other, and inclined downward towards the discharge channel 3. Moreover, a discharge side door 13 is provided at the outlet end of the breeding cavity 11. Such a design facilitates the discharge or cleaning and collection of excrement. Specifically, the breeding cavities 11 are stacked and inclined on the support frame 2 to form a multi-layer three-dimensional breeding unit 1. The discharged materials or dirt can fall and be collected by gravity. Among them, the discharge side door 13 can adopt a downward-opening hinge door 13. The support frame 2 includes a bottom support 23, a plurality of horizontal supports 21, and at least one vertical support 22. The material receiving bin 5 is disposed inside the space formed by the bottom support 23. The upper opening of the material receiving bin 5 is connected to the discharge channel 3, which can make the overall structure of the frame stable, and the outer surface is also beautiful and simple. At the same time, in order to control the discharge side doors 13 of each layer in a linkage manner, the middle connecting member 31 includes a linkage rod 311, a connecting rod 312, and an inverted bucket plate 313 mounted on the connecting rod 312. The linkage rod 311 is vertically arranged and the extending direction is the same as that of the discharge channel 3. The connecting rods 312 are symmetrically arranged on both sides of the linkage rod 311. One end of the connecting rod 312 is hinged to the linkage rod 311, and the other end is hinged to the discharge side door 13. The inverted bucket plate 313 is fixed to the upper surface of the connecting rod 312 on the side close to the linkage rod 311. The inverted bucket plate 313 is arranged with a gap from the discharge side door 13, that is, there is a certain interval between the inverted bucket plate 313 and the discharge side surface, so that the material can pass through the gap after the discharge side door 13 is opened.

[0042] It can be understood that when the linkage rod 311 moves upward, the connecting rod 312 can drive the discharge side door 13 to swing upward from bottom to top around the hinge point to open. The discharge side doors 13 on both sides of the same layer are opened and form a funnel layer. Specifically, the lower end of the downward-opening hinge door 13 can be opened upward at an angle to form a funnel-shaped buffer layer. At the same time, the included angle between the inverted bucket plates 313 on both sides of the same layer becomes smaller as the connecting rod 312 moves and forms an inverted bucket layer (i.e., a buffer layer with the opposite direction to the funnel layer). Thus, a plurality of funnel layers and a plurality of inverted bucket layers are arranged at intervals to form a multi-layer buffer rack. In this way, buffer channels similar to "Z" are formed on both sides of the middle connecting member 31. After the discharge side doors 13 are linked and opened, the materials in the breeding cavities 11 can be buffered layer by layer along the multi-layer buffer rack and then fall into the material receiving bin 5 for collection. Such a design can effectively reduce the impact force of the material falling and slow down the impact intensity, and reduce the risk of direct fall injury to the breeding objects in the high-level breeding cavities 11.

[0043] Based on the above technical solution, a movable feeding vehicle 4 is arranged beside the breeding unit 1. The feeding vehicle 4 is provided with storage cavities 41 corresponding to the number of breeding cavities 11, which is convenient for accurately and layer-by-layer feeding materials such as feed and water into the corresponding breeding cavities 11. Correspondingly, the storage cavities 41 are also inclined to facilitate feeding by gravity. And a feeding side door 411 is arranged at the outlet end of the storage cavity 41. The number of feeding side doors 411 corresponds layer by layer to the breeding cavities 11. The feeding side door 411 is an upward-opening flip door 411a or a downward-opening hinge door. After the upward-opening flip door 411a is opened, the non-hinged end can be lapped on the feeding end of the breeding cavity 11 to form a conveying bridge. Overall, it is also beneficial to realize the assembly line operation.

[0044] Specifically, as Figure 11 shown, the middle connecting member 31 preferably includes at least two linkage rods 311 and four connecting rods 312 corresponding to each layer of breeding cavities 11. Each linkage rod 311 is vertically downward and parallel. The two connecting rods 312 are symmetrically hinged on both sides of the linkage rod 311. The two connecting rods 312 on the same layer and on the same side are parallel. The anti-dumping plate 313 is laid on the connecting rods 312 on the same layer and on the same side. In this way, the buffer surface formed by the anti-dumping plate 313 can be unfolded as the linkage rod 311 moves upward to form a buffer anti-dumping layer.

[0045] In a preferred embodiment, as Figure 12 and Figure 13 shown, the bottom plate 12 of the breeding cavity 11 is set to be in a "Z" shape by bending a plurality of sections of a plate. Two adjacent and vertically staggered bottom plates 12 form the upper and lower trough surfaces of the breeding cavity 11. Through multiple bends, the compressive and anti-deformation capabilities of the bottom plate 12 and the cavity can be enhanced. Among them, the vertical support 22 can be optionally arranged on both sides of the bottom plate 12 or fixed after passing through the bottom plate. A plurality of inclined and stacked breeding cavities 11 are fixed by the vertical support 22 and erected on the bottom support 23. In this way, the vertical support 22 can strengthen the load-bearing, compressive and anti-deformation capabilities of the bottom plate 12. Additionally, optionally, the horizontal support 21 is fixedly attached to the lower side of the bottom plate 12 and / or beside the vertical support 22 to further enhance the stable support effect. Of course, for the same purpose, the bottom plate 412 of the storage cavity 41 can also be optionally set in a "Z" shape.

[0046] In an alternative embodiment, a horizontal support 21 is provided at one end of the bottom plate 12 / 412 of the breeding cavity 11 and / or the storage cavity 41 close to the discharge port, and the horizontal support 21 is an acute-angle steel 21. One folding surface of the acute-angle steel 21 extends vertically downward and is bent at an angle at the bottom end to form a convex platform portion 211. Among them, the convex platform portion 211 can be used as the hinge point of the downward-opening hinge door 411b, and the other folding surface of the acute-angle steel 21 is lapped under the inclined bottom plate 12 / 412, so that the whole inclined bottom plate 12 / 412 can be kept flat and the force is balanced.

[0047] In an alternative solution, the near-export end of the inclined bottom plate 412 of the storage cavity 41 can be formed into a convex portion 4121 after being bent vertically downward and then bent at an angle. The multi-stage bending structure and the convex portion 4121 can provide stronger compressive and anti-deformation forces for the bottom plate 412. The lower end of the feeding side door 411 is hinged to the vertically downward bending portion of the bottom plate 412 of the lower layer to form an upward-opening flip door 411a. As Figure 4 , when the upward-opening flip door 411a is turned open around the hinge point, it can overlap with the feeding port of the corresponding breeding cavity 11 to form a bridge for material transportation.

[0048] Furthermore, a movable receiving cart 6 is provided in the receiving bin 5. The upper end of the movable receiving cart 6 is open and extends out of the bottom of the breeding unit 1. In the prior art, any technology that can achieve vehicle positioning and movement through tracks, pulleys, and intelligent positioning is applicable to the movable receiving cart 6 in this solution. At the same time, a telescopic device 61 and a physical driving device 62 are preferably arranged in the middle of the movable receiving cart 6. The upper end of the telescopic device 61 can be correspondingly connected to the middle connecting member 31 and can drive the linkage rod 311 of the middle connecting member 31 to move vertically up and down. That is, the upper end of the telescopic member of the telescopic device 61 can abut against the lower end of the middle connecting member 31, thereby lifting the middle connecting member 31 upward and then driving the discharge side door 13 to open. Thus, when the discharge side door 13 is opened, the breeding target objects fall into the movable receiving cart 6 through the aforementioned multi-layer buffer racks and are then driven by the physical driving device 62 to both sides of the movable receiving cart 6. The physical driving device 62 is a sound, light, and electricity generating device or a vibrating plate. The telescopic device 61 and the physical driving device 62 can adopt the prior art solutions and will not be elaborated here.

[0049] Specifically, at least one set of upper inclined groove type louver fences 63 is preferably arranged on both sides of the physical driving device 62 for the receiving space of the movable receiving cart 6, so that the breeding objects falling from the breeding cavity 11 can be driven away from the middle by the physical driving device 62 and then climb along the inclined grooves of the louver fences 63 to both sides to achieve the online separation of the breeding targets and the materials.

[0050] Furthermore, the feeding cart 4 further includes a vertically arranged feeding channel 42 and a base 45 arranged at the lowermost end. One end of the feeding channel 42 communicates with the high end of the storage cavity 41, and the other end is provided with a diversion plate 43 corresponding to the number of the storage cavities 41. The diversion plate 43 is preferably inclined and the lower ends are all higher than the high end of the corresponding storage cavity 41. When the feed enters the feeding channel 42, it is blocked by the diversion plate 43 and guided to slide down to each layer of the storage cavity 41 in sequence. The base 45 is provided with a water tank, a water pump, and a movable device (such as a pulley, etc.). The storage cavities 41 are all provided with a water supply structure 44 communicating with the water tank.

[0051] In addition, in an alternative embodiment, a shutter 7 (not shown in the figure) may be provided at the side of the breeding cavity 11 away from the discharge channel 3, i.e., the higher end of the breeding cavity 11, and the top of the shutter 7 is hinged to the bottom plate of the breeding cavity 11 to form a downward-opening hinge door;

[0052] Furthermore, a gap through which water and materials can pass is provided between the shutter 7 and the lower bottom plate.

[0053] In the figure, the side walls of the breeding cavity 11 and the storage cavity 41 are partially omitted for the convenience of illustration. That is, stainless steel plates, wooden boards, plastic plates, etc. can be optionally provided on the non-feed and discharge port surfaces of the breeding unit 1, the feeding vehicle 4, etc. as the side walls to form a cavity shape to prevent leakage of materials from the side. At the same time, the frame can be made stable by setting support rods. In addition, Figure 9 Only the three-dimensional structure of the breeding unit is shown, and the middle connecting member is not shown. The three-dimensional structure of the middle connecting member can be understood in combination with Figure 11 understanding.

[0054] An improved multi-layer three-dimensional breeding device provided by the present application has at least the following beneficial effects:

[0055] 1. In the present application, the breeding cavity inclines inward, so that materials can fall by gravity and be collected by the receiving bin. The middle connecting member, in cooperation with the opened discharge side door and the anti-dumping plate with a smaller included angle, can form a multi-layer buffer rack, which can better make the materials fall layer by layer and play a good buffering role. At the same time, the funnel-shaped buffer rack is conducive to material collection. The breeding cavity can be unloaded or cleaned without rotation, movement or extraction. The discharge channel in the middle is conducive to air circulation and temperature control, saving time and effort in operation, and better improving the user experience. Together with supporting equipment such as a receiving bin and a feeding vehicle beside it, it is convenient for intelligent pipeline breeding. Moreover, the feeding vehicle can feed multiple breeding units at the same time, and the movable receiving vehicle can unload materials for multiple breeding units, providing the possibility for intelligent large-scale breeding;

[0056] 2. The multi-section bent bottom plate of the cavity or the extended surface of the bent cross support (angle steel) in the present application can make the cavity have better compressive and anti-deformation capabilities. The bent part can also be used as the hinge part of the hinge door. At the same time, the vertical support provides support for the bottom plate of the cavity, so as to enhance the load-bearing and anti-deformation capabilities of the bottom plate of the cavity;

[0057] 3. The bottom support of the support frame in the present application is provided with a receiving bin communicating with the discharge channel and a movable receiving vehicle, which is convenient for receiving materials and cleaning excrement, etc. The movable receiving vehicle is provided with a physical driving device and a louver fence, which is conducive to the online separation of the breeding target and materials; when the feeding side door of the storage cavity adopts an upward-opening flip door, after the door is opened, it can be used as a bridge lapped on the feeding port of the corresponding breeding cavity for convenient material transportation;

[0058] 4. The diverter plate and the storage cavity of the feed inlet channel of the movable feeding vehicle in this application are inclined, which is conducive to the batch-by-batch and portion-by-portion injection of feed from top to bottom. In addition, the water tank set on the base can stabilize the center of gravity of the feeding vehicle and provide water source at the same time. In this way, an intelligent breeding system is formed by the breeding unit, the movable feeding vehicle and the movable material receiving vehicle, which is easy to realize intelligent breeding, save labor, and can perform feeding and discharging operations for one-to-many, providing possibilities for intelligent and large-scale breeding.

[0059] The above are only the preferred embodiments of this application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of this application, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of this application.
