Description

Technical Field

[0001] This application belongs to the field of biological control and insect collection technology, and in particular relates to a collection device for the smoke bug. Background Technology

[0002] The tobacco mirid bug, belonging to the family Miridae in the order Hemiptera, plays a crucial role in agricultural ecosystems. It is a core natural enemy of many agricultural pests, exhibiting significant predation on pests such as the tobacco whitefly and greenhouse whitefly. It possesses irreplaceable ecological value in biological control. However, its population size in the natural environment is limited by various factors. To address the issue of insufficient tobacco mirid bug populations in the natural environment and meet the needs of large-scale biological control, large-scale artificial rearing has become a key technological aspect. Currently, relevant patents disclose methods for large-scale artificial rearing of tobacco mirid bugs.

[0003] Patent application number 201710065933.2 discloses a method for the industrialized production of the tobacco mirid bug. This method achieves large-scale artificial breeding through steps including legume cultivation, sterilization treatment of rice moth eggs, preparation of breeding boxes, and breeding and collection of the tobacco mirid bugs. In the breeding stage, the patent uses a plastic Lock & Lock box with two 9cm diameter ventilation holes on each of the two walls, sealed with 60-mesh mesh. A layer of vermiculite is laid at the bottom of the box, fresh broad bean seedlings are placed on the vermiculite, and sterilized rice moth eggs are sprinkled in. In the collection stage, the tobacco mirid bugs, along with the vermiculite, are placed in a medium-sized blower for separation and purification. However, due to the small size and weak body wall of both adult and nymphal tobacco mirid bugs, they tend to "grab" plant buds and leaf axils. The patent does not mention how to separate broad bean seedlings from tobacco mirid bugs. The disclosed method involves separating tobacco mirid bugs from vermiculite using a blower. However, because tobacco mirid bugs are living insects, they will adjust and strengthen their gripping force to resist separation. Therefore, it is impossible to completely and effectively collect tobacco mirid bugs from plants. Moreover, excessive suction can easily injure or kill tobacco mirid bugs, thus affecting the collection quality and subsequent biological control effect, and reducing the efficiency and benefits of large-scale artificial breeding. Therefore, it is necessary to develop a more efficient, safe, and mass-produced tobacco mirid bug collection device to improve the quality and efficiency of large-scale artificial breeding of tobacco mirid bugs and better leverage their role in the biological control of agricultural pests. Utility Model Content

[0004] This invention provides a device for collecting tobacco mirid bugs, which solves the problem that when collecting tobacco mirid bugs, the living insects adjust and strengthen their leg grip to resist separation, making it impossible to completely and effectively collect the tobacco mirid bugs on the plants, thus affecting the collection quality and efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for collecting smoke bugs, comprising: The feeding box is used to hold the smoke bug and its feeding materials. The feeding box has an openable top cover. The central box has a flip-top door on its side and a collection pipe on the top. The collection pipe is equipped with a check valve, which opens under suction conditions to control the collection flow of the smoke bugs. Multiple feeding boxes with the top cover opened are placed into the central box through the central box door. The low-temperature treatment chamber has a closable inlet and a lifting exhaust pipe at the top. After the collection box is sent into the chamber inlet by the conveying mechanism, the inlet is closed to form a closed space. The temperature inside the chamber is reduced to a preset low temperature value that reduces the activity of the smoke bug. The exhaust pipe is lowered and aligned with the collection pipe to start exhausting air, so that the smoke bug is drawn out of the feeding box by the airflow and collected efficiently.

[0006] In a preferred embodiment, the inner wall of the cryogenic processing chamber is surrounded by a cooling pipe, which is connected to a refrigeration system. The refrigeration system delivers a cooling medium into the cooling pipe to lower the temperature inside the chamber to a preset low temperature value that reduces the activity of the smoke bug.

[0007] In a preferred embodiment, the cooling system further includes a temperature control module, which includes a temperature sensor and a controller. The temperature sensor is installed in the low-temperature processing chamber to measure the temperature in the chamber in real time and feed the temperature signal back to the controller. The controller controls the working state of the refrigeration system compressor according to the preset target temperature value of the low-temperature processing chamber, so as to maintain the temperature in the low-temperature processing chamber at the preset value.

[0008] In the preferred implementation, the preset low temperature value for reducing the activity of the tobacco mirid bug is 10°C.

[0009] In a preferred implementation, the inner diameter of the extraction pipe is adapted to the outer diameter of the collection pipe, and the extraction pipe is connected to a lifting mechanism. The lifting mechanism is used to drive the extraction pipe to move up and down. When the lifting mechanism drives the extraction pipe to descend, the extraction pipe is sleeved outside the collection pipe.

[0010] In a preferred embodiment, a sealing ring is provided at the upper end of the collecting pipe. When the suction pipe is sleeved over the collecting pipe, the sealing ring is used to enhance the sealing between the suction pipe and the collecting pipe and prevent gas leakage.

[0011] In a preferred embodiment, the extraction pipe consists of a rigid pipe and a flexible pipe, both sealed at one end; the lifting mechanism is a cylinder, with its piston rod connected to the sealed end of the rigid pipe for driving the extraction pipe to move up and down; one end of the flexible pipe is connected to one side of the rigid pipe, and the other end passes through the chamber wall of the cryogenic treatment chamber, with the portion of the flexible pipe connected to the cryogenic chamber wall sealed. In another preferred embodiment, the end of the flexible pipe is connected to an activity recovery box, which is equipped with a heating mechanism to raise the temperature inside the activity recovery box to restore the activity of the smoke bug.

[0012] In a preferred embodiment, an openable blocking valve is provided at the connection position between the activity recovery chamber and the hose to prevent cold air from the low-temperature treatment chamber from entering the activity recovery chamber.

[0013] In a preferred embodiment, a filter screen is provided inside the rigid tube to filter impurities in the feeding box.

[0014] The above structure has the following beneficial effects: This device involves placing the rearing box with its top cover open into a centralized chamber, followed by low-temperature treatment and vacuuming. This eliminates the need to separate broad bean seedlings from the tobacco mirid bugs, allowing the tobacco mirid bugs to be directly extracted from the rearing box. The low-temperature treatment reduces the activity of the tobacco mirid bugs, weakening their gripping force. With the vacuuming action of the vacuum tube, the tobacco mirid bugs can be extracted from the rearing box more smoothly, greatly improving collection efficiency and enabling the collection of large numbers of tobacco mirid bugs more quickly.

[0015] This device first reduces the activity of the smoke bug by low-temperature treatment, thereby decreasing its resistance during the gas extraction and collection process. This reduces the chances of injury or death due to violent resistance, thus ensuring the quality of the collected smoke bugs and providing healthy and vigorous individuals for subsequent biological control.

[0016] The entire collection process of this device can be standardized and streamlined. Multiple breeding boxes can be placed together into a centralized container with collection pipes and check valves for processing. Because the enclosed space prevents the smoke bugs from escaping, it is suitable for large-scale, batch production needs and is conducive to promoting the industrialization and automation of artificial breeding of smoke bugs.

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0022] The present invention will now be described with reference to the accompanying drawings.

[0023] The specific solution adopted is as follows: like Figure 1-3 As shown, this utility model provides a device for collecting smoke bugs, comprising: Feeding box 5 is used to hold the smoke bug and feeding materials. The feeding box has an openable top cover. The central box 1 has a flip-top door 10 on its side and a collection pipe 11 on its top. A check valve 12 is installed inside the collection pipe. The check valve opens under suction conditions to control the collection flow of the smoke bug. Multiple feeding boxes with the top cover opened are placed into the central box through the door of the central box. The low-temperature treatment chamber 3 has a closable inlet and a lifting exhaust pipe 30 at the top. After the collection box is sent into the chamber inlet by the conveying mechanism 2, the inlet is closed to form a closed space. The temperature inside the chamber is reduced to a preset low temperature value that reduces the activity of the smoke bug. The exhaust pipe is lowered and aligned with the collection pipe to start exhausting air, so that the smoke bug is drawn out of the feeding box under the action of airflow to achieve efficient collection.

[0024] This device removes the tobacco mirid bugs directly from the rearing box by placing the open rearing box into a centralized chamber, followed by cryogenic treatment and vacuuming. This eliminates the need for separate separation of broad bean seedlings and the bugs. The cryogenic treatment reduces the bugs' activity and weakens their gripping force, allowing for smoother extraction through the vacuum tube. This significantly improves collection efficiency and enables faster collection of large quantities of tobacco mirid bugs. Excessive suction can injure or kill the bugs, affecting collection quality. This device first reduces the bugs' activity through cryogenic treatment, decreasing their resistance during vacuuming and reducing injury or death due to vigorous resistance. This ensures the quality of the collected bugs, providing healthy and vigorous individuals for subsequent biological control.

[0025] Improved collection efficiency and quality reduced losses of stink bugs during collection, ensuring a more reliable output from large-scale artificial breeding, increasing the input-output ratio of time and resources per unit, and thus enhancing the overall efficiency of large-scale artificial breeding.

[0026] The entire collection process can be standardized and streamlined. Multiple breeding boxes can be placed together in a centralized container equipped with collection pipes and check valves for processing. Because the enclosed space prevents the smoke bugs from escaping, it is suitable for large-scale, batch production needs and is conducive to promoting the industrialization and automation of artificial breeding of smoke bugs.

[0027] In addition, some pheromones can be applied to the top of the collection box near the collection tube. For example, the honeydew secreted by the whitefly nymphs contains sugar and amino acids, which not only provides nutrition for the whitefly but also guides the whitefly to locate its prey. Alternatively, plant volatiles can attract the whitefly. By concentrating the insects before low-temperature deactivation, the distribution and activity of the whitefly in the collection box can be better controlled, making the collection process more controllable.

[0028] See Figure 1 The inner wall of the low-temperature processing chamber is surrounded by a cooling pipe 31, which is connected to a cooling system 32. The cooling system delivers a cooling medium into the cooling pipe to lower the temperature inside the chamber to a preset low temperature value that reduces the activity of the smoke bug.

[0029] Specifically, the cooling system utilizes an existing refrigeration system including a compressor, responsible for compressing the refrigerant gas, increasing its pressure and temperature to power the refrigeration cycle. The high-temperature, high-pressure refrigerant gas discharged from the compressor enters the condenser, where it transfers heat to the surrounding environment, cooling the refrigerant gas and liquefying it into a high-pressure liquid. As the high-pressure liquid refrigerant passes through the expansion valve, its pressure drops sharply, and some of the liquid refrigerant vaporizes, becoming low-temperature, low-pressure wet vapor. This low-temperature, low-pressure wet vapor refrigerant enters the evaporator, absorbs heat from the surrounding environment, and vaporizes, thereby lowering the temperature around the evaporator. In the smoke bug collection device, the evaporator is the refrigeration pipes surrounding the inner wall of the low-temperature treatment chamber. The refrigerant flows within the pipes, absorbing heat from the chamber to achieve cooling.

[0030] A temperature sensor is installed inside the cryogenic processing chamber to sense temperature changes in real time and convert the temperature signal into an electrical signal. The temperature sensor feeds back the measured electrical signal to the controller, which processes and analyzes the signal to obtain the current actual temperature value inside the chamber. The controller compares the actual temperature value with a preset target temperature value for the cryogenic processing chamber (e.g., 10°C). If the actual temperature is higher than the target temperature, further cooling is needed; if the actual temperature is lower than the target temperature, the cooling capacity needs to be reduced or cooling should be stopped. Based on the comparison result, the controller sends a control signal to the compressor of the refrigeration system to adjust the compressor's operating state. For example, when the actual temperature is higher than the target temperature, the controller will increase the compressor's power or extend its operating time to allow more refrigerant to participate in the circulation and accelerate the cooling rate; when the actual temperature approaches or reaches the target temperature, the controller will reduce the compressor's power or make it operate intermittently to reduce the cooling capacity and maintain the temperature stable at the preset value.

[0031] The advantage of setting the preset low temperature of 10℃ to reduce the activity of the smoker bug is that, under normal ambient temperatures, the smoker bug is highly active and has a strong gripping force, causing it to cling tightly to plant buds and leaf axils, which makes collection very difficult. When the temperature in the low-temperature treatment chamber is lowered to around 10℃ (10℃±0.5℃), the smoker bug's metabolic rate slows down, its bodily functions are inhibited to some extent, its activity is significantly reduced, and its gripping force weakens. At this time, with the help of the suction tube, the smoker bug is more easily extracted from the rearing box, greatly improving collection efficiency.

[0032] If forceful suction or other rough collection methods are used, the smoke bugs are easily injured or even killed due to their fierce resistance. However, by reducing their activity through low-temperature treatment, the smoke bugs' resistance during collection decreases, reducing physical damage caused by struggling. Furthermore, a temperature of around 10°C will not cause fatal damage to the smoke bugs. After collection, restoring them to a suitable temperature environment allows them to resume normal life and reproduction, ensuring the quality of the collected smoke bugs and providing healthy, vigorous individuals for subsequent biological control efforts.

[0033] In a preferred embodiment of this application, the inner diameter of the suction pipe is adapted to the outer diameter of the collection pipe, and the suction pipe is connected to a lifting mechanism. The lifting mechanism 33 is used to drive the suction pipe to move up and down. When the lifting mechanism drives the suction pipe to descend, the suction pipe is sleeved outside the collection pipe.

[0034] Specifically, within the cryogenic processing chamber, a station is set up for the centralized container, precisely aligned with the exhaust pipe. This design can draw inspiration from existing assembly line operations. More specifically, two blocking cylinders are symmetrically installed on both sides of the conveyor mechanism that transports the centralized container. Simultaneously, laser alignment sensors are installed at pre-set precise positions. When the centralized container moves with the conveyor mechanism and reaches the location of the laser alignment sensor, the sensor immediately detects its arrival and sends a signal. Upon receiving this signal, the blocking cylinders on both sides of the conveyor mechanism quickly extend their piston rods, firmly blocking the centralized container and stopping it at the predetermined position, preventing further movement.

[0035] At this point, the lifting mechanism connected to the extraction pipe begins to operate. Following a preset program, the lifting mechanism drives the extraction pipe to descend vertically. Because the inner diameter of the extraction pipe is carefully designed to perfectly match the outer diameter of the collection pipe, it accurately fits the outside of the collection pipe when it reaches the appropriate position, achieving a tight fit. After the connection between the extraction and collection pipes is complete, the extraction process begins. The extraction operation continues, for example, with a set extraction time of 3 minutes, to ensure effective collection of target objects such as stink bugs from the collection box. After the 3-minute extraction time ends, the blocking cylinder receives a signal again, and its piston rod quickly retracts, releasing the obstruction to the collection box. Driven by the conveying mechanism, the collection box continues to move along the predetermined route, leaving the current workstation and entering the subsequent production process. (The above-mentioned structures and actions are not shown in the figure, but based on conventional knowledge and technical logic in this field, those skilled in the art can clearly understand and implement this design.)

[0036] Furthermore, a sealing ring 110 is provided at the upper end of the collection pipe. When the suction pipe is sleeved outside the collection pipe, the sealing ring is used to enhance the sealing between the suction pipe and the collection pipe and prevent gas leakage.

[0037] In a preferred embodiment of this application, the extraction pipe consists of a rigid pipe 300 and a flexible pipe 301, both of which are closed at one end; the lifting mechanism is a cylinder, whose piston rod is connected to the closed end of the rigid pipe, and is used to drive the extraction pipe to move up and down; one end of the flexible pipe is connected to one side of the rigid pipe, and the other end passes through the chamber wall of the cryogenic treatment chamber, and the part of the flexible pipe connected to the cryogenic chamber wall is sealed.

[0038] In the overall structural design, the piston rod of the cylinder is securely connected to the closed end of the rigid pipe in the extraction pipe. Considering the potential for cold air leakage when the piston rod passes through the wall of the cryogenic treatment chamber, a portion of the cylinder body is directly connected to the chamber wall. However, in actual operation, each time the door of the cryogenic cooling chamber is opened to insert or remove the central chamber, the chamber inevitably comes into contact with the external environment, leading to some degree of cold loss and temperature fluctuation. Therefore, ensuring the cryogenic cooling chamber remains sealed when closed is crucial for the overall system operation, reducing energy consumption and improving the overall efficiency and economic benefits of the cryogenic treatment system. One end of the flexible hose connects to one side of the rigid pipe, typically secured with a connector or clamp. The other end of the hose passes through the cryogenic chamber wall, and the connection point is sealed. The other end fits tightly against the cryogenic chamber wall, achieving a reliable seal through a special structural design. Because the hose is not taut within the chamber, it can be raised and lowered. In a preferred embodiment of this application, the end of the hose is connected to the activity recovery chamber 4. The activity recovery chamber is equipped with a heating mechanism, which consists of a high-performance heating element, a precise temperature sensor, and an intelligent temperature control system. The heating element generates heat quickly and evenly, while the temperature sensor monitors the temperature inside the chamber in real time and feeds the data back to the temperature control system. The temperature control system precisely controls the operating state of the heating element according to preset temperature parameters, thereby stably raising the temperature inside the activity recovery chamber to the optimal temperature range required for the activity recovery of the *Ixodes spp.*, thus helping the *Ixodes spp.* regain its vitality.

[0039] In a preferred embodiment of this application, an openable check valve 40 is installed at the connection between the reactivation chamber and the hose. For example, a one-way check valve can also be used, typically composed of a valve body, valve disc, and spring. During the evacuation process, the negative pressure inside the hose causes the valve disc to overcome the spring's preload and open upwards, allowing gas to flow from the cryogenic treatment chamber to the reactivation chamber, ensuring a smooth evacuation process. When evacuation stops, the spring force causes the valve disc to quickly fall back and fit tightly against the valve seat, forming an effective seal and preventing cold air from the cryogenic treatment chamber from flowing back into the reactivation chamber through the connection point, thus maintaining a relatively stable temperature inside the reactivation chamber.

[0040] In a preferred embodiment of this application, the rigid tube serves as the key channel for gas flow in the system, and a filter screen 3000 is installed inside it. This filter screen is primarily for effectively filtering impurities within the rearing box. Inside the rearing box, due to plant growth and activity, some impurities are generated, with plant debris such as broad bean seedlings being a common type. Regarding vermiculite in the rearing box, its relatively large particles and weight generally make it difficult for it to be sucked up by the airflow. However, in special cases where vermiculite particles are very fine and extremely light, they may enter the rigid tube with the airflow. Regarding the filter screen material, a soft material is chosen to prevent the smoke bugs from being injured or even killed by colliding with the filter screen during airflow. This provides effective protection when the smoke bugs accidentally touch the filter screen, reducing their mortality rate.

[0041] From the perspective of practical application, the design scheme of this application has significant advantages in the collection of *Echinochloa crus-galli*. It can greatly improve the collection efficiency and increase the collection volume. Although a small amount of impurities may still remain in the gas drawn into the activity recovery chamber after filtration, the environment inside the activity recovery chamber is more concentrated and controllable compared to collecting *Echinochloa crus-galli* directly in the rearing box, providing more convenient conditions for collection and making the collection work easier and more efficient.

[0042] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
