Description

Technical Field

[0001] This utility model belongs to the technical field of breeding devices, and more specifically, it relates to a breeding device for larvae of the juniper giant spur wasp. Background Technology

[0002] The rearing device for jujube spur wasp larvae provides a stable habitat, sufficient food supply, and suitable environmental conditions to ensure the larvae can grow and develop normally under artificial intervention. However, during the rearing process of jujube spur wasp larvae, the larvae will continuously produce feces, and the food fed will also produce residual waste. If this waste accumulates in the rearing device for a long time, it will breed bacteria, damage the rearing environment, and affect the survival rate and growth quality of the larvae. Therefore, it is necessary to clean the waste in the rearing device regularly.

[0003] However, traditional juniper larvae rearing devices often have an integrated fixed structure for the rearing box and waste collection, lacking an independent waste collection and circulation path. When it is necessary to clean the waste in the rearing box, the larvae must be carefully removed from the rearing box and transferred to a temporary rearing container. After the waste is cleaned up, the larvae are put back into the rearing box. This can easily cause mechanical damage to the larvae during the larval transfer process, reducing the larval survival rate. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rearing device for larvae of the juniper giant mottle wasp, which solves the technical problem in the prior art where the rearing box and waste collection structure are integrated and fixed, lacking an independent waste collection and conduction path, and requiring the transfer of larvae to clean up waste, resulting in larvae being susceptible to mechanical damage and having a reduced survival rate.

[0005] The purpose and effectiveness of this utility model's device for raising larvae of the Chinese tallow chrysanthemum are achieved through the following specific technical means:

[0006] A rearing device for larvae of the juniper giant chafer wasp includes a main box with doors on both sides forming rearing chambers. A ventilation section, including ventilation pipes, is located inside the main box. The rearing chambers are divided into two cultivation zones by the center line of the ventilation pipes, and multiple rearing components are arranged within each cultivation zone. Each rearing component includes a rearing box with a rearing trough. A partition plate is fitted inside the rearing trough, forming two rearing zones. A collection zone is located at one end of each rearing zone. A detachable collection box is located at the bottom of the rearing box, and multiple collection pipes are arranged on both sides of the collection box, connecting the collection box to the collection zone via the collection pipes.

[0007] According to a preferred embodiment, multiple sets of the feeding components are arranged longitudinally along the cultivation area. A semi-circular slot is provided on one side of the feeding box, and the ventilation pipe is locked in the slot. Multiple sets of positioning slots are provided on the feeding box, and locking parts are provided on both sides of the partition plate, and the locking parts are locked in the positioning slots.

[0008] According to a preferred embodiment, the feeding trough is provided with partitions at both ends, the feeding area and the collection area are separated by the partitions, and a through groove is provided on the partitions, through which the feeding area communicates with the collection area; multiple sets of clamping plates are provided on both sides of the feeding trough, which form limiting grooves with the partitions; a barrier plate is provided at one end of the feeding area, and the two sides of the barrier plate are respectively clamped in the corresponding two sets of limiting grooves and in contact with the partitions, covering the through groove.

[0009] According to a preferred embodiment, the feeding trough is provided with drop troughs at both ends, the drop troughs are located in the collection area, and the collection pipe passes through the drop troughs; the collection box is provided with a collection cavity, and a filter screen is provided in the collection cavity, which divides the collection cavity into a first collection area and a second collection area through the filter screen.

[0010] According to a preferred embodiment, a dustproof net is provided on the top opening of the feeding box, and the dustproof net is detachably connected to the feeding box by Velcro.

[0011] According to a preferred embodiment, a ventilation slot is provided on one side of the feeding box, and a ventilation pipe passes through the ventilation slot, dividing the ventilation slot into two sections. Multiple sets of ventilation channels are provided on the feeding box, and the ventilation channels are located on one side of the feeding slot. Multiple sets of ventilation openings are provided on one side of the feeding slot, and the ventilation openings are connected to the ventilation channels. A ventilation path is formed through the ventilation slot, the ventilation channels, and the ventilation openings. Multiple sets of air outlets are provided on both sides of the ventilation pipe, and the ventilation pipe is connected to the ventilation path through the multiple sets of air outlets.

[0012] According to a preferred embodiment, the vent protrudes from the inside of the feeding tank and is inclined upwards at 45°.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This device establishes an independent waste collection and circulation path of "rearing area - collection area - collection box" by setting up an independent collection area inside the rearing box, and equipped with a detachable collection box and a through collection pipe. Waste cleaning can be completed without removing the larvae: During cleaning, feces and residue from the rearing area can enter the collection area through the partition channel, and then fall into the collection box through the drop channel and collection pipe. The collection box can be removed and cleaned separately, without disturbing the normal habitat of the larvae. At the same time, the barrier plate can flexibly block the channel. Closing the channel before cleaning the collection box can prevent larvae from accidentally entering the collection area. This completely solves the mechanical damage problem caused by the need to transfer larvae when cleaning waste in traditional integrated structures, greatly improves the survival rate of larvae, eliminates the need for larvae transfer, reduces manual labor intensity, and shortens the cleaning time.

[0015] 2. Optimize the stability of the larval rearing environment to provide suitable conditions for larval growth. On the one hand, the device constructs a complete ventilation path through ventilation pipes, ventilation slots, ventilation channels, and ventilation openings, which can evenly deliver the airflow in the ventilation pipes to the rearing tank. The 45° inclined protruding ventilation openings can prevent the airflow from blowing directly on the larvae, while ensuring air circulation in the rearing chamber, effectively reducing the risk of odor and bacterial growth caused by waste accumulation. On the other hand, the rearing box is fixed to the ventilation pipes by a semi-circular slot, realizing the longitudinal and orderly arrangement of multiple rearing components. This makes full use of the space inside the main box while preventing the rearing components from shaking and affecting the larvae's habitat. The partition plate can flexibly adjust the size of the rearing area through the locking part and positioning slot to adapt to the rearing needs of different numbers of larvae. The dustproof net can prevent external impurities from entering the rearing tank, further ensuring a clean rearing environment and providing stable and suitable conditions for larval growth.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 5 As shown, this utility model provides a rearing device for larvae of the juniper giant wasp. The core supporting component is the main body box 11, which is made of high-strength plastic material, providing stable support for the internal rearing structure and preventing external collisions from affecting the larvae inside. On both sides of the main body box 11, there is a door panel 12, which is connected to the main body box 11 by hinges and can be opened and closed flexibly. When the door panel 12 is closed, it and the internal space of the main body box 11 together form a closed rearing cavity. This rearing cavity can reduce the interference of external environmental temperature and humidity fluctuations on larval growth, while preventing external debris and natural enemies from entering the rearing area.

[0026] A ventilation section for regulating the air environment of the rearing chamber is centrally located inside the main body box 11. The core component of this ventilation section is a cylindrical ventilation pipe 21 made of transparent PVC material, facilitating observation of internal airflow. The ventilation pipe 21 runs horizontally through the main body box 11, with both ends extending to the outside, allowing connection to external air supply equipment for temperature and environmental control. The rearing chamber within the main body box 11 is evenly divided into two cultivation zones along the centerline of the ventilation pipe 21. These zones are symmetrically distributed on both sides of the ventilation pipe 21. This layout ensures consistent ventilation and temperature conditions in both zones, facilitating comparative rearing experiments. Each cultivation zone contains multiple sets of rearing components for larvae. These multiple sets increase the number of larvae that can be reared per unit space and facilitate the classification and rearing of larvae from different batches and at different growth stages.

[0027] On the bottom end face of the rearing box 31, there is a detachable collection box 34. The collection box 34 is a box structure with an open top, made of polypropylene, which has good corrosion resistance. On both sides of the top of the collection box 34, there are multiple sets of collection tubes 35 for guiding waste. The collection tubes 35 are hollow cylindrical structures, one end of which is connected to the internal space of the collection box 34, and the other end extends upward and connects to the collection area at the bottom of the rearing box 31. Through the guiding effect of the collection tubes 35, the waste in the rearing area can fall smoothly into the collection box 34, realizing the centralized collection of waste. At the same time, the detachable design of the collection box 34 makes it convenient to remove the collection box 34 for cleaning periodically without moving the larvae in the rearing box 31.

[0028] The setup of two rearing areas enables "alternating rearing + undisturbed cleaning": During daily rearing, larvae and feed are placed in only one rearing area, while the other rearing area remains empty, allowing the larvae to concentrate on the rearing area with feed for activity and feeding; when it is necessary to clean the rearing area with feed (such as cleaning up residual food scraps or changing the rearing substrate), fresh feed is first placed in the empty rearing area. At this time, due to the larvae's tendency to move towards fresh feed, they will gradually move to the rearing area with newly placed feed; after most of the larvae have migrated to the new rearing area, the partition 33 is repositioned into the rearing trough 32, making the two rearing areas independent again. At this time, the original rearing area can be cleaned without moving or contacting the larvae, avoiding interference or damage to the larvae during the cleaning process, while also ensuring the continuity of the rearing process and not affecting the normal feeding and growth of the larvae.

[0029] like Figure 2 , Figure 3 As shown, multiple sets of feeding components are distributed within each culture area, arranged sequentially along the longitudinal direction of the culture area. A certain gap is maintained between adjacent sets of feeding components to ensure smooth airflow between the sets and prevent localized air stagnation caused by overcrowding. A semi-circular slot 36 is provided on the side of the feeding box 31 near the ventilation pipe 21. The diameter of the slot 36 matches the outer diameter of the ventilation pipe 21, allowing the ventilation pipe 21 to fit snugly within the slot 36. Through the engaging and locking mechanism of the slot 36 and the ventilation pipe 21, the feeding box 31 can be stably fixed to both sides of the ventilation pipe 21, preventing displacement during the feeding process and maintaining a fixed distance between the feeding box 31 and the ventilation pipe 21, ensuring a stable subsequent ventilation path.

[0030] A rearing trough 32 is formed on the top of the rearing box 31. Multiple positioning grooves 51 are formed along the length of the rearing trough 32. The positioning grooves 51 are rectangular grooves and are evenly distributed on both sides of the inner wall of the rearing trough 32. On both sides of the partition plate 33, there are locking parts 37 that are adapted to the positioning grooves 51. The locking parts 37 are raised rectangular structures and their size matches the size of the positioning grooves 51. When the partition plate 33 is locked in the rearing trough 32, the locking parts 37 on both sides of the partition plate 33 can be locked in the positioning grooves 51 on both sides of the rearing trough 32. Through the cooperation of the locking parts 37 and the positioning grooves 51, the partition plate 33 can be stably fixed in the rearing trough 32. At the same time, the positioning grooves 51 at different positions can be selected to install the partition plate 33 according to the number of larvae and their growth stage, so as to adjust the space size of the two rearing areas and improve the space utilization of the rearing trough 32.

[0031] At both ends of the rearing trough 32 along its length, there is a partition 38. The partition 38 is a thin plastic plate perpendicular to the bottom surface of the rearing trough 32, and its height is the same as the depth of the rearing trough 32. Through the blocking effect of the partition 38, the interior of the rearing trough 32 can be divided into two parts: a rearing area and a collection area, clearly separating the space for larvae to inhabit and the space for waste collection, and preventing larvae from entering the collection area. At the middle of the partition 38, there is a channel 39 for waste to flow through. The channel 39 is a rectangular hole, and its height is lower than the height of the partition 38. Feces and leftover food scraps generated in the rearing area can enter the collection area from the rearing area through the channel 39, realizing the directional flow of waste. On the inner walls of both sides of the rearing trough 32 along its length, there are multiple sets of retaining plates 41. The retaining plates 41 are raised rectangular plastic blocks. The multiple sets of retaining plates 41 and the partition 38 form limiting slots for installing the barrier plates 42. The width of the limiting slots matches the thickness of the barrier plates 42. At one end of the rearing area near the partition 38, a barrier plate 42 is installed. The barrier plate 42 is a thin plastic plate with a height consistent with the depth of the rearing trough 32 and a width consistent with the width of the rearing trough 32. When it is necessary to block the connection between the rearing area and the collection area, the edges on both sides of the barrier plate 42 can be respectively locked into the corresponding two sets of limiting slots. At this time, one end face of the barrier plate 42 is in close contact with the side of the partition 38, completely covering the through slot 39 on the partition 38, thereby preventing larvae in the rearing area from entering the collection area. It can also prevent odors in the collection area from entering the rearing area when cleaning the collection box 34.

[0032] At both ends of the feeding trough 32 along its length, and at the bottom of the collection area, there are drop troughs 43 for waste to fall into. The drop troughs 43 are circular holes with a diameter slightly larger than the outer diameter of the collection pipe 35. The end of the collection pipe 35 away from the collection box 34 extends upward into the drop trough 43, and the outer wall of the collection pipe 35 fits snugly against the inner wall of the drop trough 43. This fit ensures that all waste in the collection area falls completely into the collection pipe 35, preventing waste from leaking out from the gap between the collection pipe 35 and the drop trough 43. Inside the collection box 34, there is a collection cavity for storing waste. The volume of the collection cavity is designed according to the number of animals in the feeding unit and the cleaning cycle, and can meet the waste storage needs for several days. Inside the collection chamber, a filter screen 44 is horizontally installed. The filter screen 44 is made of stainless steel, and its mesh size is designed according to the particle size of the waste, which can separate feces from residual food residue. Through the filtering effect of the filter screen 44, the collection chamber can be divided into upper and lower layers. The upper layer is the first collection area, which is used to collect residual food residue, and the lower layer is the second collection area, which is used to collect feces and sewage. This layered collection method facilitates the subsequent classification and treatment of different types of waste and reduces cross-contamination during the waste treatment process.

[0033] A dustproof net 45, made of nylon, covers the opening at the top of the rearing box 31. This net has good breathability and small mesh size, preventing dust, lint, and other debris from entering the rearing trough 32 without obstructing airflow. Matching Velcro fasteners are attached to the edges of both the dustproof net 45 and the opening at the top of the rearing box 31. The male and female sides of the Velcro fasteners are secured to the dustproof net 45 and the rearing box 31, respectively. The Velcro fasteners securely fix the dustproof net 45 to the opening at the top of the rearing box 31. When it is necessary to add food, observe larvae, or clean the rearing trough 32, simply detach the Velcro fasteners to remove the dustproof net 45 from the rearing box 31. This convenient and reusable method allows for easy removal of the net.

[0034] like Figure 2 , Figure 4 , Figure 5As shown, on the side of the rearing box 31 near the ventilation pipe 21, a ventilation groove 46 is provided for the ventilation pipe 21 to pass through. The ventilation groove 46 is a U-shaped groove with its opening facing the top of the rearing box 31. The width of the ventilation groove 46 matches the outer diameter of the ventilation pipe 21. When the rearing box 31 is secured to the ventilation pipe 21 via the slot 36, the ventilation pipe 21 passes through the ventilation groove 46, dividing the ventilation groove 46 into upper and lower sections. These two sections of the ventilation groove 46 can serve as channels for air to enter the rearing box 31. Inside the rearing box 31, and on one side of the rearing tank 32, multiple sets of ventilation channels 47 for air circulation are provided. The ventilation channel 47 is a hollow rectangular channel, with one end connected to the ventilation groove 46 and the other end extending to the side wall of the rearing tank 32. On the side wall of the rearing tank 32 near the ventilation channel 47, multiple sets of ventilation openings 48 are provided for supplying air into the rearing tank 32. Each ventilation opening 48 is a circular hole, with one end connected to the ventilation channel 47 and the other end connected to the internal space of the rearing tank 32. Through the sequential connection of the ventilation channel 46, ventilation channel 47, and ventilation openings 48, a complete ventilation path is formed, allowing external air to enter the rearing tank 32 along this path. On both sides of the ventilation pipe 21, multiple sets of air outlets 22 are provided for exhausting air. These air outlets 22 are circular holes, evenly distributed on the pipe wall of the ventilation pipe 21. When air is introduced into the ventilation pipe 21, it can be exhausted through the multiple air outlets 22 into the ventilation channel 46, and then through the ventilation channel 47 and ventilation openings 48 into the rearing tank 32, thus refreshing the air in the rearing tank 32, reducing the carbon dioxide concentration, and removing odors, providing a fresh air environment for the larvae.

[0035] The ventilation opening 48, located on the side wall of the rearing tank 32, protrudes inward from the end furthest from the ventilation channel 47, with the opening facing upward and at a 45° angle to the bottom surface of the rearing tank 32. This inclined arrangement allows the airflow entering the rearing tank 32 from the ventilation opening 48 to flow upward along the inclined direction, preventing the airflow from blowing directly onto the larvae at the bottom of the rearing tank 32. This prevents the larvae from experiencing hypothermia or being impacted by the airflow due to direct airflow. At the same time, the upward airflow can be more evenly distributed throughout the entire space of the rearing tank 32, ensuring that the air in different locations within the rearing tank 32 is effectively refreshed, allowing all larvae to be in a fresh air environment.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
