TECHNICAL FIELD

[0001] The present application relates to the technical field of white scale rearing, and specifically provides a mangrove Ceroplastes krugeri rearing device for scientific research. BACKGROUND

[0002] The mangrove Ceroplastes krugeri has biological characteristics such as a short reproductive cycle, strong environmental adaptability, and fast population growth, and has become an important model organism for studying the ecological adaptation mechanism of invasive pests, the interaction between pests and hosts, and new green control technologies. The existing device has a single heating element inside the closed box, and mostly uses a bottom heating pad or a top heating lamp, which can only realize temperature regulation of a local area of the box, cannot eliminate the influence of the physical effect of the upward movement of hot air and the downward movement of cold air in the box, and the temperature difference between the top and the bottom of the box often reaches 5-8 DEG C, causing uneven growth of parallel experimental samples; and the existing device mostly uses fixed spray head drip irrigation for nutrient solution supply, and does not set a supply structure with an adjustable position.

[0003] Correspondingly, there is a need for a new mangrove Ceroplastes krugeri rearing device for scientific research to solve the above technical problems. SUMMARY

[0004] The present application aims to solve the above technical problems, i.e., to solve the problems of poor temperature control effect and poor nutrient solution supply effect of the existing white scale rearing device.

[0005] The present application provides a mangrove Ceroplastes krugeri rearing device for scientific research, characterized in that the rearing device comprises: a rearing cylinder, wherein a nutrient solution dish is arranged at the bottom of the rearing cylinder for receiving and collecting nutrient solution; and a plurality of layers of placing racks are arranged in the rearing cylinder, and the placing racks are used for placing rearing branches and leaves; a controller, which is arranged on the side of the rearing cylinder; a temperature control module, which is installed on the inner wall of the rearing cylinder and is electrically connected with the controller; a nutrient solution supply module, which is arranged on the top of the rearing cylinder, and a position adjusting structure is arranged on the nutrient solution supply module and is electrically connected with the controller, and is used for spraying nutrient solution to each part in the rearing cylinder.

[0006] Based on the above structural arrangement, the bottom nutrient solution dish can receive the nutrient solution not absorbed by the branches and leaves, avoid the waste caused by the direct dropping of the nutrient solution to the tank bottom, and reduce the risk of mold growth in the tank. The controller is linked with the temperature control module and the nutrient solution supply module to realize the automatic operation of temperature control and nutrient solution spraying, without frequent manual intervention, which can reduce the damage of manual operation to the stable environment in the breeding tank, reduce human error, provide a stable and controllable breeding environment for the mangrove white peach estid, ensure the consistency of environmental variables in scientific experiments, and improve the accuracy and reliability of experimental data.

[0007] In the preferred technical solution of the above-mentioned mangrove white peach estid scientific breeding device, the temperature control module includes a temperature sensor, a first heater and a second heater, the temperature sensor is arranged on the inner wall of the breeding tank, the temperature sensor is electrically connected with the controller, and is used for transmitting the temperature signal in the breeding tank to the controller, and the first heater and the second heater are both installed on the inner wall of the breeding tank, and the first heater and the second heater are electrically connected with the controller.

[0008] Based on the above structural arrangement, the temperature sensor in the temperature control module cooperates with the double heaters to monitor the temperature in the breeding tank in real time and feed back the signal to the controller. The controller accurately controls the start and stop of the first heater and the second heater according to the temperature deviation. Compared with a single heating element, the design of double heaters can respond to temperature changes faster and avoid large temperature fluctuations in the breeding tank.

[0009] In the preferred technical solution of the above-mentioned mangrove white peach estid scientific breeding device, the first heater is arranged as a sheet-shaped heater, and the second heater is arranged as a strip-shaped heater.

[0010] Based on the above structural arrangement, the first heater is arranged as a sheet-shaped heater, and the second heater is arranged as a strip-shaped heater, which can realize complementary heating by utilizing the structural characteristics of the two kinds of heaters. The sheet-shaped heater has a large heating area and uniform heat distribution, which can provide a basic and uniform environmental temperature in the breeding tank, avoiding local high or low temperature. The strip-shaped heater can supplement the local low-temperature area in the breeding tank, further reduce the temperature difference between different areas in the breeding tank, avoid the difference in growth rate of insects caused by uneven temperature distribution, ensure the consistency of scientific samples, and improve the reliability of experimental results.

[0011] In the preferred technical solution of the above-mentioned mangrove white peach estid scientific breeding device, the temperature sensor is arranged in two, one of which is arranged at the top of the breeding tank, and the other is arranged at the bottom of the breeding tank.

[0012] Based on the above structure, the temperature sensors are arranged at the top and bottom of the feeding tank respectively, which can monitor the temperature gradient in the vertical direction of the tank in real time. Compared with a single temperature sensor that can only monitor the local temperature, the double sensor design can more comprehensively reflect the overall temperature distribution in the feeding tank. The controller can accurately control the working state of the first and second heaters according to the temperature difference between the top and bottom, such as starting the heater near the bottom when the bottom temperature is too low, and appropriately reducing the power of the heater near the top when the top temperature is too high, so as to balance the temperature in the vertical direction of the tank, avoid the growth of insects at different heights on the placing frame due to the temperature difference between the top and bottom, and ensure the consistency of the feeding environment of multiple parallel samples, providing reliable conditions for the horizontal comparison of scientific research data.

[0013] In the preferred technical solution of the above-mentioned mangrove Calocostoma white shield pest research feeding device, the nutrient solution supply module includes a supply bottle, a hose and an atomizing nozzle, the supply bottle is arranged on the outer wall of the feeding tank, the first end of the hose is inserted into the inside of the supply bottle, the atomizing nozzle is installed on the top of the feeding tank, the second end of the hose is communicated with the atomizing nozzle, and the second end of the hose is provided with a pump.

[0014] Based on the above structure, the external supply bottle facilitates researchers to supplement the nutrient solution without opening the feeding tank, avoids the internal temperature and humidity fluctuations caused by opening the tank, and ensures the environmental stability. The atomizing nozzle can atomize the nutrient solution into fine droplets, which can be more evenly attached to the surface of the feeding branches and leaves compared to traditional drip irrigation or spraying, avoiding local nutrient solution excess causing branch and leaf rot, or local nutrient solution deficiency causing insect food shortage. The pump can accurately control the delivery amount and spraying speed of the nutrient solution, avoiding the supply amount error caused by manual pouring, and ensuring the consistency of the nutrient solution dose for each spraying.

[0015] In the preferred technical solution of the above-mentioned mangrove Calocostoma white shield pest research feeding device, the position adjusting structure includes a sliding rail, a sliding block and a driving structure, the sliding rail is arranged on the top of the feeding tank, the sliding block is slidingly arranged on the sliding rail, and the driving structure is arranged on the sliding block and used to drive the sliding block to slide on the sliding rail.

[0016] Based on the above structure, the sliding of the sliding block can cover all areas on the top of the feeding tank, avoiding the dead angle caused by the fixed nozzle, and ensuring that all feeding branches and leaves can uniformly obtain nutrient solution. Manual adjustment of the nozzle position is not required, which reduces the disturbance to the environment in the feeding tank. At the same time, the driving structure controls the movement of the sliding block, which can realize the standardization of the spraying path, further ensure the uniformity of each spraying, avoid the growth difference of insects caused by uneven spraying, ensure the homogeneity of the research samples, and improve the effectiveness of the experimental data.

[0017] In the preferred technical scheme of the above-mentioned mangrove kandaulaspidae research feeding device, the driving structure comprises a driving motor and a roller, the driving motor is arranged in the sliding block, the roller is arranged on the sliding rail in a rolling manner, the roller is connected with the output end of the driving motor, and the driving motor is electrically connected with the controller.

[0018] Based on the above structure, the motor-driven roller sliding is more stable than manual pushing in controlling the moving speed and stopping position of the sliding block, avoids the uneven force during manual operation from causing the sliding block to jam or deviate, ensures the nozzle to move at a uniform speed along the preset path, and further improves the spraying uniformity.

[0019] In the preferred technical scheme of the above-mentioned mangrove kandaulaspidae research feeding device, the length of the sliding rail is consistent with the length of the inside of the top of the feeding cylinder, and the cross section of the sliding rail is in a U-shaped structure.

[0020] Based on the above structure, the length of the sliding rail is consistent with the length of the inside of the top of the feeding cylinder, which can ensure that the sliding block can cover the entire transverse range of the top of the feeding cylinder when sliding, completely eliminate the dead angle of spraying, and ensure that all the feeding branches and leaves can be covered by the nutrient solution; the cross section of the sliding rail is in a U-shaped structure, which can form a more stable limit for the sliding block compared with ordinary rectangular or circular sliding rails, and ensure that the sliding block always moves along the preset track during sliding.

[0021] In the preferred technical scheme of the above-mentioned mangrove kandaulaspidae research feeding device, the atomizing nozzle has an atomizing particle diameter of 50-100 μm, and a spraying angle of 60-90°.

[0022] Based on the above structure, the atomizing particle diameter of the atomizing nozzle is set to 50-100 μm, which can avoid the branches and leaves from being too wet due to large particles, and also avoid the liquid droplets from evaporating too quickly due to small particles, which is just suitable for the demand of the mangrove kandaulaspidae for the wetness of branches and leaves, and facilitates the insect body to absorb the nutrient solution; the spraying angle of 60-90° can balance the coverage range and the spraying intensity: too large angle is easy to cause the liquid droplets to splash to the wall of the feeding cylinder, causing waste, and too small angle is easy to form a dead angle, which can ensure that the nozzle can cover a certain width of the branch and leaf area during movement, and realize uniform spraying in the whole range by cooperating with the movement of the sliding block, thereby improving the utilization efficiency of the nutrient solution and the feeding effect.

[0023] In the preferred technical scheme of the above-mentioned mangrove kandaulaspidae research feeding device, a humidity control module is further arranged in the feeding cylinder, the humidity control module comprises a humidity sensor and a humidifier, the humidity sensor is arranged on the inner wall of the feeding cylinder, the humidifier is installed on the top of the feeding cylinder, and the humidity sensor and the humidifier are electrically connected with the controller.
