Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquaculture equipment technology, specifically relating to a belt for aquaculture, a reciprocating belt aquaculture equipment, and a multi-layer reciprocating belt aquaculture frame. Background Technology
[0002] In fly larvae farming, the total weight and volume of the mixture of feed, larvae, adult larvae, larvae sand, and waste residue before and after farming are large, making it impossible to discharge the feed from the farming tank quickly and evenly. This is one of the main problems causing low efficiency and high labor costs in traditional farming. Therefore, it is crucial to quickly and evenly spread and discharge the materials from the farming tank. Utility Model Content
[0003] This utility model provides a livestock belt, a reciprocating belt livestock farming device, and a multi-layer reciprocating belt livestock farming frame to address the shortcomings described in the prior art.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A conveyor belt for aquaculture includes a first belt and a second belt, the ends of which are connected. The first belt consists of a first main belt, a first edge belt I, and a first edge belt II. The first edge belt I and the first edge belt II are located on either side of the first main belt, and the sum of the widths of the first main belt, the first edge belt I, and the first edge belt II is equal to the width of the second belt. The lengths of the first main belt, the first edge belt I, and the first edge belt II are equal, and the lengths of both the first main belt and the second belt are not less than the length of the aquaculture trough. The width of the first main belt is not less than the width of the aquaculture trough. The first main belt and the second belt serve as the main bearing surfaces for the aquaculture materials. Since the widths of the first main belt and the second belt exceed the width of the aquaculture trough, there are no gaps in the side panels of the aquaculture trough, preventing aquaculture insects from escaping or hiding through gaps. The aquaculture materials are spread and discharged through the alternating unwinding and rewinding of the first main belt and the second belt. If the first main belt is unwound, the second belt is rewound, and vice versa. The different structures of the first and second belts allow for a clear distinction between the two functional belts, enabling the switching between the spreading, conveying, and discharging functions of the materials. The total length of the first and second belts must be at least twice the length of the aquaculture tank.
[0006] In a preferred embodiment of this utility model, the first edge belt I is vertically attached to one side wall of the aquaculture tank; the first edge belt II is vertically attached to the other side wall of the aquaculture tank; and both edges of the second belt are folded upwards to attach to the side wall of the aquaculture tank. The first edge belt I and the first edge belt II move along the side wall of the aquaculture tank, and a pressure plate is also provided on the side wall of the aquaculture tank. There is a gap between the inner side wall of the pressure plate and the side wall of the aquaculture tank, which allows the folded edges of the first edge belt I, the first edge belt II, and the second belt to pass through and plays a role in smoothing and guiding.
[0007] This utility model also provides a reciprocating belt aquaculture device, including the aforementioned belt, a first belt winding mechanism, a second belt winding mechanism, and an aquaculture trough; the first belt winding mechanism includes a main belt winding structure, a first edge belt winding structure, and a second edge belt winding structure; the first belt winding mechanism is located outside one end of the aquaculture trough; the second belt winding mechanism is located outside the other end of the aquaculture trough; the free end of the first main belt is wound onto the first belt winding structure, the free end of the first edge belt I is vertically wound onto the first edge belt winding structure, the free end of the first edge belt II is vertically wound onto the second edge belt winding structure, the first edge belt winding structure and the second edge belt winding structure are parallel, and the winding direction of the first edge belt winding structure is perpendicular to the winding direction of the first belt winding structure; the free end of the second belt is wound onto the second belt winding mechanism; the end where the first main belt and the second belt are connected is located on the aquaculture trough, the first edge belt I is vertically attached to one side wall of the aquaculture trough; the first edge belt II is vertically attached to the other side wall of the aquaculture trough; both edges of the second belt are folded up and attached to the side wall of the aquaculture trough. The first edge belt I and the first edge belt II are wound and unwound vertically, while the first main belt is wound and unwound horizontally. However, the first main belt, the first edge belt I, and the first edge belt II are wound or unwound synchronously. The first main belt, the first edge belt I, and the first edge belt II are formed by directly cutting the two sides of a single belt. The second belt is wound horizontally, and the winding and unwinding are opposite to those of the first main belt.
[0008] As a preferred embodiment of this utility model, the main belt winding structure, the first edge belt winding structure, and the second edge belt winding structure are wound and unwound synchronously; the winding and unwinding directions of the main belt winding structure and the second belt winding mechanism are opposite.
[0009] As a preferred embodiment of this utility model, the main belt winding structure, the first edge belt winding structure, and the second edge belt winding structure share a single winding power source.
[0010] In a preferred embodiment of this utility model, the winding power includes a winding motor, a first gearbox, and a second gearbox. The output shaft of the winding motor is drivenly connected to the input shaft of the first gearbox. The first output shaft of the first gearbox is horizontally arranged and drivenly connected to the main belt winding roller of the main belt winding structure. The second output shaft of the first gearbox is vertically arranged and drivenly connected to the first edge winding roller of the first edge belt winding structure. The other end of the main belt winding roller is drivenly connected to the first input shaft of the second gearbox. The first output shaft of the second gearbox is vertically arranged and drivenly connected to the second edge winding roller of the second edge belt winding structure.
[0011] In a preferred embodiment of this invention, the main belt winding structure and the first edge belt winding structure share a single winding power mechanism; the main belt winding structure and the second edge belt winding structure share another winding power mechanism, and the two winding power mechanisms move synchronously and in the same direction. In other words, the first belt winding mechanism is driven by two power sources simultaneously.
[0012] As a preferred embodiment of this utility model, the winding power mechanism includes a winding motor and a gearbox. The output shaft of the winding motor is drivenly connected to the input shaft of the gearbox. The first output shaft of the gearbox is horizontally arranged and is drivenly connected to the main belt winding roller of the main belt winding structure. The second output shaft of the gearbox is vertically arranged and is drivenly connected to the first edge winding roller of the first edge belt winding structure or the second edge winding roller of the second edge belt winding structure.
[0013] As a preferred embodiment of this utility model, the first belt winding mechanism, whether driven by a single power source or a dual power source, is equipped with a braking structure for each winding power mechanism.
[0014] In a preferred embodiment of this invention, the second belt winding mechanism includes a second winding motor and a second winding roller. The second winding motor is driven by the second winding roller, and at least one end of the second winding roller is driven by the second winding motor and is parallel to the main belt winding roller. The free end of the second belt is wound onto the second winding roller. That is, the second winding roller can be driven by either a single power source or a dual power source, with a dual power source being preferred.
[0015] As a preferred embodiment of this utility model, vertical guide wheels are installed on both sides of the end of the breeding tank facing the first belt winding mechanism. The first edge belt I and the first edge belt II each have a corresponding vertical guide wheel, and are wound and unwound under the action of the corresponding vertical guide wheels.
[0016] As a preferred embodiment of this utility model, guide side plates are installed on both sides of the end of the breeding tank, and the maximum width of the two guide side plates is greater than the width of the breeding tank. The two guide side plates on each side of the breeding tank form a trumpet-shaped structure. For the first main belt, the first edge belt I, and the first edge belt II, when they are outside the breeding tank, the first edge belt I and the first edge belt II are separated from the first main belt. Only when they are inside the breeding tank are the first edge belt I and the first edge belt II overlap and contact the edge of the first main belt. For the second belt, when it enters the breeding tank, the edge of the second belt will be folded upward and adhere to the side wall of the breeding tank under the action of the side wall of the breeding tank. When it is outside the breeding tank, the edge of the second belt gradually returns to straight.
[0017] In a preferred embodiment of this invention, lifting gates are installed inside the breeding trough, specifically one lifting gate near the second belt winding mechanism and another near the first belt winding mechanism. During material distribution and unloading, the lifting gates are in the raised state, not obstructing the passage of the first and second belts. During breeding, the lifting gates are lowered to block both ends of the breeding trough, creating a breeding space with the lifting gates, the bottom of the trough, and the side panels.
[0018] This utility model also provides a multi-layer reciprocating belt aquaculture rack, including a support frame, and several layers of aquaculture equipment as described above are arranged parallel to each other in the vertical direction of the support frame.
[0019] In a preferred embodiment of this invention, each layer of the aquaculture equipment is equipped with a discharge hopper on the side near the second belt winding mechanism, with the discharge port of the upper discharge hopper corresponding to the inlet of the lower discharge hopper. The aquaculture insects and materials from the upper layer of the aquaculture equipment fall into the discharge hopper, and the materials from the upper discharge hopper fall into the lower discharge hopper. The last discharge hopper then falls onto the conveyor belt for transport.
[0020] This invention employs two belts with different configurations for material conveying and discharge. By switching between the first and second belts during winding and unwinding, material is conveyed and discharged from the breeding tank. During discharge, the cultured insects are also discharged, eliminating the need for a turning and scraping machine to remove the insects and material. This avoids crushing the insects during scraping, and because scrapers operate reciprocally, their insect removal efficiency is relatively low. This invention improves the survival rate and extraction efficiency of the cultured insects. Furthermore, it allows for multi-layered, three-dimensional breeding, further enhancing breeding efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1:
[0030] A type of livestock belt, such as Figure 1As shown, the system includes belts, specifically a first belt 1 and a second belt 2, connected at their ends. The first belt 1 consists of a first main belt 100, a first edge belt I101, and a first edge belt II102. The first edge belt I101 and the first edge belt II102 are located on either side of the first main belt 100, and the sum of the widths of the first main belt 100, the first edge belt I101, and the first edge belt II102 is equal to the width of the second belt 2. The first belt and the second belt are integrally formed, with one end of the belt cut to the required length. The lengths of the first main belt 100, the first edge belt I101, and the first edge belt II102 are equal, and the lengths of both the first main belt 100 and the second belt 2 are not less than the length of the aquaculture trough, preferably both longer than the length of the aquaculture trough, because both the first main belt and the second belt can be fully covered by the aquaculture trough. The width of the first main belt 100 is not less than the width of the aquaculture trough. The first and second main belts serve as the primary load-bearing surfaces for the aquaculture materials. Both belts are wider than the aquaculture trough, ensuring no gaps exist in the trough's side panels and preventing the escape and hiding of aquaculture insects. The alternating unwinding and rewinding of the first and second main belts facilitates the spreading and discharge of the aquaculture materials. If the first main belt is unwinding, the second belt is rewinding, and vice versa. The different structures of the first and second belts allow for easy identification of their functions, enabling the switching between material spreading, conveying, and discharge. The total length of the first and second belts is at least twice the length of the aquaculture trough.
[0031] In use, the first edge belt I101 is vertically attached to one side wall of the aquaculture tank; the first edge belt II102 is vertically attached to the other side wall of the aquaculture tank; and both edges of the second belt 2 are folded up to fit against the side wall of the aquaculture tank. The first edge belts I101 and II102 move along the side wall of the aquaculture tank, and a pressure plate is also provided on the side wall of the aquaculture tank. There is a gap between the inner side wall of the pressure plate and the side wall of the aquaculture tank, which allows the folded edges of the first edge belts I101, II102, and the second belt to pass through and plays a smoothing and guiding role.
[0032] The first main belt, the first edge belt I101, and the first edge belt II102 are wound and unwound synchronously. The first edge belt I101 and the first edge belt II102 are wound and unwound vertically, the first main belt is wound and unwound horizontally, the second belt is wound and unwound horizontally, and the winding and unwinding directions of the second belt and the first belt are opposite.
[0033] When the first belt is in the winding state, the second belt is in the unwinding state; when the first belt is in the unwinding state, the second belt is in the winding state. The first and second belts are in a single-layer reciprocating winding and unwinding state, rather than a conventional annular cycle.
[0034] Example 2:
[0035] A reciprocating belt aquaculture device, such as Figure 2 As shown, it includes a belt, a first belt winding mechanism, a second belt winding mechanism, and a breeding trough 3; the breeding trough is a trough-type structure with side plates, and the belt is the belt from Embodiment 1, such as... Figure 1 As shown, the first belt winding mechanism includes a main belt winding structure, a first edge belt winding structure, and a second edge belt winding structure. The first belt winding mechanism is located outside one end of the aquaculture tank, and the second belt winding mechanism is located outside the other end of the aquaculture tank. The main belt winding structure, the first edge belt winding structure, and the second edge belt winding structure are wound and unwound synchronously. In this embodiment, the main belt winding structure and the first edge belt winding structure share a winding power mechanism, and the main belt winding structure and the second edge belt winding structure share another winding power mechanism. That is, the first belt winding structure is a dual-power drive.
[0036] The winding power mechanism includes a winding motor 6 and a gearbox 13. A commercially available gearbox can be used. For the winding power mechanism shared by the main belt winding structure and the first edge belt winding structure, the output shaft of the winding motor 6 is connected to the input shaft of the gearbox 13. The first output shaft of the gearbox is horizontally arranged and is connected to one end of the main belt winding roller of the main belt winding structure. The second output shaft of the gearbox is vertically arranged and is connected to the first edge winding roller of the first edge belt winding structure.
[0037] For the winding power mechanism shared by the main belt winding structure and the second edge belt winding structure, the output shaft of the winding motor 6 is connected to the input shaft of the gearbox 13. The first output shaft of the gearbox is horizontally arranged and is connected to the other end of the main belt winding roller of the main belt winding structure. The second output shaft of the gearbox is vertically arranged and is connected to the second edge winding roller of the second edge belt winding structure.
[0038] Furthermore, the winding power mechanism is equipped with a braking structure, which can stop the main belt winding structure, the first edge belt winding structure, and the second edge belt winding structure when the machine stops.
[0039] The second belt winding mechanism includes a second winding motor 8 and a second winding roller 9. At least one end of the second winding roller is connected to the output shaft of the second winding motor. That is, the second winding roller can be driven by a single power source or by two power sources. This embodiment demonstrates a dual-power drive, where each end of the second winding roller is connected to a second winding roller. The second winding roller is parallel to the main belt winding roller 7. The free end of the second belt is wound onto the second winding roller, and both edges of the second belt 2 are folded up to fit against the side wall of the aquaculture tank. The second belt winding mechanism also includes a brake structure 14.
[0040] The ends of the second belt 2 and the first main belt 100 are located on the breeding tank 3. The free end of the first main belt 100 is wound on the main belt winding roller 7. The free end of the first edge belt I101 is vertically wound on the first edge winding roller, and the first edge belt I101 is vertically attached to one side wall of the breeding tank 3. The free end of the first edge belt II102 is vertically wound on the second edge winding roller, and the first edge belt II102 is vertically attached to the other side wall of the breeding tank. The first edge winding roller and the second edge winding roller are parallel, and the winding direction of the first edge winding roller is perpendicular to the winding direction of the main belt winding roller 7.
[0041] The first edge belt I101 and the first edge belt II102 are wound and unwound vertically, while the first main belt is wound and unwound horizontally. However, the first main belt, the first edge belt I101, and the first edge belt II102 are wound or unwound synchronously. The first main belt, the first edge belt I101, and the first edge belt II102 are formed by directly cutting the two sides of a single belt. The second belt is wound horizontally, and the winding and unwinding are opposite to those of the first main belt.
[0042] In order to enable the first belt and the second belt to be wound up and unwound quickly without breaking, vertical guide wheels are installed on both sides of the end of the breeding tank facing the first belt winding mechanism. The first edge belt I and the first edge belt II each have a corresponding vertical guide wheel, and are wound up and unwound under the action of the corresponding vertical guide wheel.
[0043] Meanwhile, vertical pressure rollers are also installed inside the two side walls of the breeding tank. The vertical pressure rollers contact the edges of the first edge belt I101, the first edge belt II102 and the second belt and can rotate in place along the contact belt surface, so that the edges of the first edge belt I101, the first edge belt II102 and the second belt can be tightly attached to the side wall of the breeding tank when winding and unwinding.
[0044] Guide side plates 4 are also installed on both sides of the end of the breeding tank. The maximum width of the two guide side plates is greater than the width of the breeding tank. The guide side plates are used to install the first belt winding mechanism and the second belt winding mechanism. The two guide side plates on each side of the breeding tank form a trumpet-shaped structure.
[0045] For the first main belt, the first edge belt I101, and the first edge belt II102, when they are outside the breeding tank, the first edge belt I101 and the first edge belt II102 are separated from the first main belt. Only when they are inside the breeding tank are the first edge belt I101 and the first edge belt II102 overlap and contact the edge of the first main belt. For the second belt, when it enters the breeding tank, the edge of the second belt will be folded upward and adhere to the side wall of the breeding tank under the guidance of the guide side plate. When it is outside the breeding tank, the edge of the second belt gradually returns to straight.
[0046] Furthermore, a stretching roller 10 is installed on each of the two guide side plates between the main belt winding roller 7 and the breeding trough, and on each of the two guide side plates between the second winding roller 9 and the breeding trough. The two ends of the stretching roller 10 are respectively mounted on the guide side plates through a bearing to guide and stretch the first main belt and the second belt.
[0047] To prevent insects from escaping during rearing, lifting gates are installed inside the rearing trough. Specifically, one lifting gate is located near the second belt winding mechanism and another near the first belt winding mechanism (not shown in the diagram). During feeding and unloading, the lifting gates are raised, not obstructing the passage of the first and second belts. During rearing, the lifting gates are lowered to block both ends of the rearing trough, creating a rearing space with the lifting gates, the bottom of the trough, and the side panels.
[0048] Example 3:
[0049] A reciprocating belt aquaculture device, such as Figure 3 As shown, the main belt winding structure, the first edge belt winding structure, and the second edge belt winding structure share a winding power mechanism. The first edge belt winding structure and the second edge belt winding structure are not shown in the figure. Of course, they can also have their own power, as long as synchronous movement is ensured. The winding and unwinding directions of the main belt winding structure and the second belt winding mechanism are opposite and synchronous.
[0050] The winding power mechanism includes a winding motor 6, a first gearbox 11, and a second gearbox 12. Commercially available gearboxes can be used. The output shaft of the winding motor is connected to the input shaft of the first gearbox. The first output shaft of the first gearbox is horizontally positioned and connected to the main belt winding roller 7 of the main belt winding structure. The second output shaft of the first gearbox 11 is vertically positioned and connected to the first edge winding roller of the first edge belt winding structure. The other end of the main belt winding roller 7 is connected to the first input shaft of the second gearbox 12. The first output shaft of the second gearbox 12 is vertically positioned and connected to the second edge winding roller of the second edge belt winding structure. The rest is the same as in Embodiment 2.
[0051] Example 4:
[0052] A multi-layer reciprocating belt aquaculture rack, such as Figure 4-6 As shown, the system includes a support frame 5, with several layers of aquaculture equipment as described in Example 2 arranged parallel to each other in the vertical direction of the support frame. To discharge the aquaculture insects and materials from each layer, a discharge hopper 14 is provided on the side of each layer near the second belt winding mechanism. The discharge port of the upper layer's discharge hopper corresponds to the inlet of the lower layer's discharge hopper. The number of layers is determined according to the type of aquaculture insect. Initially, the top layer is fed with insects and materials via an insect-adding device and a feeding device. The first belt winding mechanism winds up the first belt, and materials and aquaculture insects are added to the second belt until it is full. Then, a lifting gate lowers to cover the aquaculture trough, allowing aquaculture to take place within the aquaculture area. After a certain period of aquaculture on the top layer, the lifting gate rises, and the second belt winding mechanism rotates in the opposite direction to wind up the second belt. The first belt is unwound, and the insects and materials on the second belt are received by the discharge hopper and fall to the next layer. The second belt of the next layer is unwound, and the first belt is wound up; this process is repeated to achieve recycling.
