Description

Technical Field

[0001] This utility model relates to the field of bat moth larvae breeding equipment, and more particularly to a bat moth larvae cultivation device. Background Technology

[0002] As the sole host insect for the precious traditional Chinese medicine Cordyceps sinensis, the large-scale artificial breeding of ghost moth larvae is crucial for solving the shortage of Cordyceps sinensis resources and achieving sustainable utilization. Ghost moth larvae spend most of their lives in the soil and are extremely sensitive to environmental factors such as humidity, temperature, ventilation, and population density. They require consistently high humidity (usually 70%–80%), suitable oxygen concentration (18%–20%), and effective prevention of cannibalism between different instars to ensure their healthy growth and high survival rate.

[0003] Currently, the artificial breeding of ghost moth larvae mostly adopts the decentralized box or underground pit breeding mode, which generally suffers from problems such as low precision in controlling environmental parameters, reliance on manual management, and low breeding efficiency. In particular, existing equipment often struggles to balance the contradictory needs of humidity and ventilation. Maintaining humidity in a closed environment for a long time can easily lead to the accumulation of carbon dioxide and a decrease in oxygen concentration, while frequent ventilation can cause a sudden drop in humidity, both of which can seriously affect the normal growth and development of larvae.

[0004] Therefore, how to develop a culture device for bat moth larvae that can automatically maintain a stable high-humidity environment inside the chamber without frequent human intervention, and can initiate effective directional gas exchange in a timely manner according to the internal air conditions, has become a technical problem that urgently needs to be solved by people in this field.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] 1) This utility model monitors the environmental parameters inside the chamber in real time through humidity and oxygen sensors, and uses a PLC controller to intelligently link the ring spray assembly and the diagonally arranged convection fans. When the humidity is insufficient, the spray is automatically started and the fans are used to promote the uniform diffusion of water mist, achieving efficient and uniform humidification. When the oxygen concentration is lower than the set threshold, the baffle assembly can be automatically controlled to open and the forced ventilation program can be started to form a directional airflow from bottom to top or from top to bottom, effectively avoiding dead zones in ventilation. While maintaining a high humidity environment inside the chamber, it ensures fresh air and solves the contradiction between humidification and ventilation in the breeding of bat moth larvae.

[0016] 2) This utility model uses a manually removable first partition plate, a platform with through holes, and crawling channels on both sides to form a larval grouping structure. After a certain period of rearing, the operator only needs to remove the first partition plate, and the smaller larvae can crawl into the secondary rearing chamber through the through holes of the platform. This achieves automatic group rearing according to body size, which significantly reduces the cannibalism between larvae of different ages, effectively controls the rearing density, and improves the survival rate and the convenience of rearing management.

[0017] 3) This utility model uses a water collection tank assembly set at the bottom of the tank to effectively collect condensed water and excess liquid in the tank by using inclined plates and baffles. After impurities are filtered by the bottom filter screen, the water is pumped back to the storage tank by a second micro water pump to achieve recycling. This significantly reduces the consumption of clean water in the breeding process, reflects the design concept of intensive use of water resources, and reduces the maintenance cost of long-term breeding.

[0032] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] like Figures 1-12As shown, a cultivation device for bat moth larvae includes a box 1, a support assembly 2, a rearing box 3, a convection fan 4, a wind deflector assembly 5, an annular spray assembly 6, a water collection tank 8, a water storage tank 9, a first micro water pump 10, and a second micro water pump 11. Ventilation windows 101 are provided on both the left and right sides of the box 1, respectively located in the upper middle and lower middle parts of the left and right sides of the box 1, and arranged diagonally. Two convection fans 4 are mounted on one side of each ventilation window 101 via support frames and are located within the inner cavity of the box 1. The annular spray assembly 6 is fixedly connected to the outlet side of each convection fan 4. A set of first sliding grooves 102 is provided on the other side of each ventilation window 101. Two sets of wind deflector assemblies 5 are respectively located on the left and right sides of the box 1 and are slidably connected to the box 1 via the first sliding grooves 102. Multiple sets of support assemblies 2 are vertically adjustable and arranged within the inner cavity of the box 1, and are connected to the box 1. The inner wall of the housing 1 is slidably connected, and the breeding box 3 is snapped onto the top of the support assembly 2. The water inlet of the annular spray assembly 6 extends outward after penetrating the inner wall of the housing 1, and is connected to the first micro water pump 10 through the first water inlet pipe 601. The first micro water pump 10 is connected to the water storage tank 9 located on the top of the housing 1. The water collection tank 8 is located at the bottom of the inner cavity of the housing 1, and its outlet is connected to the second micro water pump 11 through the first water outlet pipe 801. The second micro water pump 11 is connected to the water storage tank 9. A humidity sensor and an oxygen sensor are installed on the inner wall of the housing 1. Multiple sets of LED fluorescent lamps 7 are arranged at the top of the inner cavity of the housing 1 and the bottom of the support assembly 2, and are located above the breeding box 3. The humidity sensor, oxygen sensor, convection fan 4, wind baffle assembly 5, LED fluorescent lamps 7, first micro water pump 10 and second micro water pump 11 are all electrically connected to the PLC controller located inside the housing 1.

[0034] Specifically, the front side of the housing 1 is provided with an opening, and a sealing door 103 is hinged to the housing wall near the opening side of the housing 1. The sealing door 103 is provided with a glass observation window 104, a display screen 12 and an adjustment button 13. The glass observation window 104 is located at the center of the sealing door 103. The display screen 12 and the adjustment button 13 are located above the glass observation window 104. The display screen 12 and the adjustment button 13 are both electrically connected to the PLC controller.

[0035] Specifically, the wind deflector assembly 5 includes a drive motor 501, a threaded rod 502, and an n-shaped baffle 503. The n-shaped baffle 503 is slidably connected to the first slide groove 102 via a set of first sliders 504 symmetrically arranged at its bottom end. The top of the n-shaped baffle 503 is provided with a threaded block 505 that matches the threaded rod 502. The drive motor 501 is mounted on the top of the side wall of the housing 1 via a mounting base. One end of the threaded rod 502 is connected to the power output end of the drive motor 501, and the other end of the threaded rod is threadedly connected to the threaded block 505. The drive motor 501 is electrically connected to the PLC controller.

[0036] Specifically, the oxygen sensor is set to continuously monitor the oxygen concentration in the air inside chamber 1. According to the physiological characteristics of the bat moth larvae, the optimal environmental oxygen concentration range required for their growth and development is 18% to 20% (volume fraction). When the oxygen sensor detects that the oxygen content in the air inside chamber 1 is continuously lower than 17%, the PLC controller will determine that it is in an oxygen-deficient state and automatically start the forced ventilation program.

[0037] Specifically, in this embodiment, one ventilation window 101 is located in the lower middle part of the left side of the box wall, and the other ventilation window 101 is located in the upper middle part of the right side of the box wall. When forced ventilation is required, the PLC controller first starts the drive motor 501 of the baffle assembly 5. The motor drives the threaded rod 502 to rotate, which in turn drives the threaded block 505 that meshes with the threaded rod to move. Finally, the n-shaped baffle 503 slides smoothly along the first slide groove 102, so that the originally blocked ventilation window 101 is fully exposed. Then, the PLC controller starts the convection fan 4 located at the lower middle ventilation window 101 according to the predetermined program to send fresh air into the box. The polluted air in the inner cavity of the box 1 will be discharged from the upper middle ventilation window 101, forming a directional airflow from bottom to top, avoiding dead zones in ventilation. At the same time, the user can also set it in the opposite direction to form a downward ventilation airflow.

[0038] Specifically, under normal conditions without forced ventilation, the n-shaped baffle 503 blocks most of the ventilation windows 101. However, its upper and lower edges are not completely flush with the windows, but are intentionally left with continuous gaps of 3mm to 6mm. This allows the internal environment of the chamber 1 to maintain a slight connection with the external atmosphere, enabling slow and continuous micro-gas diffusion and exchange. This not only effectively prevents the chamber 1 from becoming a dead zone due to complete sealing, avoiding excessive accumulation of carbon dioxide and a continuous spontaneous decrease in oxygen concentration, but also provides basic gas exchange for the larvae. At the same time, after the n-shaped baffle 503 blocks most of the ventilation area of ​​the ventilation windows 101, it can significantly slow down the outflow rate of humid air inside the chamber and also hinder the intrusion of dry air from the outside. This plays an important auxiliary role in maintaining the stability of the high humidity environment inside the chamber.

[0039] Specifically, the supporting assembly 2 includes a first support plate 201, a second support plate 202, guide rods 203, and locking bolts 204. The four guide rods 203 are vertically arranged on the left and right sides of the inner cavity of the box body 1. The first support plate 201 is slidably connected to the guide rods 203 through guide grooves 205 on its left and right sides, and is threadedly connected to the positioning holes 2031 equally spaced on the guide rods 203 through the locking bolts 204. The top of the first support plate 201 has a second sliding groove 206. The second support plate 202 is slidably connected to the second sliding groove 206 through a second slider 207 at its bottom. The top of the second support plate 202 has a limiting hole 208. The breeding box 3 is inserted into the limiting hole 208 through a limiting post at its bottom and is placed on top of the second support plate 202. The LED fluorescent lamp 7 is arranged at the bottom of the first support plate 201.

[0040] Specifically, the breeding box 3 further includes a first partition plate 301, a second partition plate 302, a crawling channel 303, a platform 304, and handles 305. The second partition plate 302 is horizontally arranged in the inner cavity of the breeding box 3, dividing the inner cavity of the breeding box 3 into two independent chambers: a main breeding chamber and a secondary breeding chamber. The first partition plate 301 is detachably inserted into the inner cavity of the main breeding chamber and is spaced apart from the second partition plate 302. The platform 304 is located on the side of the second partition plate 302 near the first partition plate 301, and the top of the platform 304 has a through hole that penetrates the second partition plate 302 and communicates with the secondary breeding chamber. Crawling channels 303 for the larvae of the bat moth are provided on both sides of the platform 304. The two handles 305 are respectively located on the left and right sides of the breeding box 3.

[0041] Specifically, the bottom of both the main and secondary rearing chambers is lined with a layer of culture soil, mixed with Polygonaceae plant tubers that the ghost moth larvae love to eat as feed. In actual use, the young ghost moth larvae are all placed in the main rearing chamber for rearing. Due to differences in feeding ability, the growth rate of the ghost moth larvae is different. In order to prevent the phenomenon of larger larvae cannibalizing smaller ones, after a certain period of rearing, the first partition plate 301 is manually pulled out, allowing the smaller ghost moth larvae to crawl out from the through hole at the top of the platform 304 and slide down into the secondary rearing chamber for rearing. This can solve the problem of excessive rearing density caused by larval growth, reduce the problem of ghost moth larvae cannibalizing each other, and effectively separate ghost moth larvae at different ages.

[0042] Specifically, the design of the crawler channel 303 and platform 304 in this utility model is an existing structure. The crawler channel 101 and platform 102 in the reference patent (patent number: CN207544110U) will not be described in detail here.

[0043] Specifically, the annular spray assembly 6 further includes an annular water pipe 602 and multiple nozzles 603. The annular water pipe 602 is fixedly installed on the air outlet side of the convection fan 4. The multiple nozzles 603 are arranged at equal angles on the side of the annular water pipe 602 facing away from the convection fan 4. One end of the first water inlet pipe 601 is connected to the water inlet end of the annular water pipe 602, and the other end passes through the cavity wall of the housing 1 and is connected to the water outlet of the first micro water pump 10.

[0044] Specifically, based on the physiological habit of the bat moth larvae to prefer shade and moisture, the suitable air humidity in their artificial breeding environment should be maintained at 70% to 80%. When the humidity sensor detects that the air humidity in the inner cavity of the box 1 is continuously lower than 65%, the PLC controller will automatically start the air humidification operation.

[0045] Specifically, since the convection fan 4 is fixedly connected to the inner wall of the housing 1 through the support frame, and there is a certain gap between the fan body and the housing wall, the convection fan 4 can still operate normally and promote the circulation of air inside the housing even when the ventilation window 101 is closed.

[0046] When the humidification operation is started, the first micro water pump 10 pumps water from the water storage tank 9 into the first water inlet pipe 601, which then delivers it to the annular water pipe 602, and finally sprays it out in the form of water mist through the nozzle 603. At the same time, the two convection fans 4 installed inside the box start synchronously. The convection fan 4 located in the upper middle part promotes airflow at the top of the box, while the convection fan 4 located in the lower middle part promotes airflow at the bottom. The two airflows converge and mix in the middle area of ​​the inner cavity of the box 1, thereby effectively driving the air inside the box to circulate along the inner wall. During this process, the fine water mist sprayed by the nozzle 603 mixes fully with the flowing air and diffuses evenly to all areas inside the box, thereby achieving efficient and uniform air humidification and continuously maintaining a suitable humidity environment for the growth and development of the bat moth larvae.

[0047] Specifically, the water collection tank 8 further includes a water collection tank body 802, a baffle plate 803, a filter screen 804, and an inclined plate 805. The water collection tank body 802 is placed at the bottom of the inner cavity of the tank body 1. The two baffle plates 803 are respectively arranged on the front and rear sides of the top of the water collection tank body 802. The inclined plate 805 is fastened to the side wall of the inner cavity of the tank body 1 by bolts, and the inclined plate 805 is inclined and located between the two baffle plates 803. The inclined plate 805 is sandwiched between the inner cavity wall of the tank body 1 and the inner cavity wall of the tank body 1. The water collection tank body 802 has a sealing rubber sheet. The inclined bottom end of the inclined plate 805 and the open end of the top of the water collection tank body 802 together form a water inlet 806. The bottom of the water collection tank body 802 is a sloping structure, and its sloping direction is opposite to that of the inclined plate 805. The filter screen 804 is set at the bottom of the inner cavity of the water collection tank body 802. The first water outlet pipe 801 is connected to the inner cavity of the water collection tank body 802, and the water inlet end of the first water outlet pipe 801 is located at the lowest point of the sloping bottom of the water collection tank body 802.

[0048] Specifically, in this embodiment, the water collection tank body 802 is placed at the bottom of the inner cavity of the tank body 1, mainly for collecting excess water in the tank environment. The inclined plate 805 and the baffle plate 803 set in the tank body 1 together form a water guide channel structure, which can effectively collect the condensate flowing down the tank wall or in the air, and introduce it into the water collection tank body 802 through the water inlet 806. The bottom of the water collection tank body 802 is designed with an inclination, and its inclination direction is opposite to that of the inclined plate 805, so that the collected water can flow naturally to the lower side under the action of gravity. During the flow of water along the bottom slope, it will pass through the filter screen 804 set at the lower position, thereby filtering out impurities in the water and avoiding clogging or contamination of the pipeline. In addition, the inclined plate 805 also plays a role in limiting and assisting in positioning the water collection tank body 802 in terms of structure, so as to keep it stable in the tank.

[0049] Specifically, the outlet of the water collection tank body 802 is located at the lowest point of its bottom slope. The inlet of the first water outlet pipe 801 is connected to the outlet. Through the operation of the second micro water pump 11, the water filtered and collected in the water collection tank body 802 can be pumped back to the water storage tank 9 for storage, thereby realizing the recycling of water resources and effectively reducing the consumption of clean water in the breeding process.

[0050] The usage process of this utility model is as follows:

[0051] First, place the device stably, connect the external power supply, open the sealing door 103, add sufficient clean water to the water storage tank 9, and check whether the water collection tank 8 is installed in place; then, according to the breeding needs, adjust the first support plate 201 and the second support plate 202 to the appropriate height and lock them by adjusting the locking bolts 204 on the support assembly 2, and then place the breeding box 3 stably on the second support plate 202, ensuring that the limiting post at the bottom is firmly inserted into the limiting hole 208; then, lay the culture soil layer and mix an appropriate amount of feed into the main breeding chamber and the auxiliary breeding chamber of the breeding box 3, and insert the first partition plate 301 to divide the breeding area of ​​the main breeding chamber and the platform 304.

[0052] Next, the young larvae of the ghost moth are placed into the main breeding chamber, the sealing door 103 is closed, and the appropriate humidity and oxygen parameters are set by adjusting button 13. The PLC controller then begins to automatically monitor and regulate the environment inside the chamber 1.

[0053] Furthermore, during daily operation, the humidity sensor continuously monitors the humidity inside the chamber. If it is lower than the set threshold, the system automatically starts the first micro water pump 10 and the ring spray assembly 6, and at the same time starts the convection fan 4 to promote the uniform diffusion of water mist. The oxygen sensor detects the oxygen concentration inside the chamber in real time. When it is lower than 17%, the drive motor 501 will drive the n-shaped baffle 503 to open the corresponding ventilation window 101, and start the diagonally arranged convection fans 4 to perform forced ventilation, forming a directional airflow to refresh the air.

[0054] Then, as the larvae grow, to avoid overcrowding or cannibalism, the first partition plate 301 can be manually pulled out, and smaller individuals can enter the secondary breeding chamber through the through holes on the platform 304, thus achieving group rearing according to body size.

[0055] Finally, excess water in the tank 1 is collected into the water collection tank body 802 through the inclined plate 805 and the baffle plate 803 structure. After being filtered by the filter screen 804, it is pumped back to the water storage tank 9 by the second micro water pump 11 through the first water outlet pipe 801 for recycling. Users can view the environmental status inside the tank in real time through the glass observation window 104 and the display screen 12, and open the sealed door 103 to operate when cleaning or harvesting is required.
