Description

Technical Field

[0001] This utility model relates to the field of entomology, and in particular to a device for collecting egg masses of the beet armyworm. Background Technology

[0002] In the field of entomology, research on the beet armyworm is an important area. In studies on the beet armyworm, the oviposition cage selection test is a common research method. In this test, host plants are usually placed in the cage and a certain number of adult moths are released to lay eggs on the host plants. However, the beet armyworm has a special oviposition habit. Its egg masses are laid not only on the host plants, but also on the gauze of the cage.

[0003] Currently, the main method for collecting egg masses of the beet armyworm is to gently brush them with a soft brush. This traditional method has several drawbacks: First, due to their fragility and the instability of the soft brush, the egg masses are easily scattered during brushing, resulting in egg loss and affecting the accuracy of subsequent sample counts. Second, additional containers or tools are needed to hold the egg masses, making the process cumbersome and reducing efficiency. Third, some egg masses are highly adhesive and difficult to brush off with a soft brush; forcibly brushing them may cause them to break, crush, or dry out, resulting in physical damage and potentially affecting their biological activity, further leading to sample loss. Fourth, the scales on the surface of the egg masses severely interfere with subsequent egg counting, leading to inaccurate counting results and affecting the reliability of the research data.

[0004] In summary, traditional methods for collecting Spodoptera litura egg masses have many problems in practical applications, affecting the accuracy and efficiency of Spodoptera litura research. Therefore, there is a particular need for a device for collecting Spodoptera litura egg masses. Utility Model Content

[0005] The purpose of this invention is to provide a device for collecting egg masses of *Spodoptera litura*, addressing the following issues with traditional methods described in the background: First, during the brushing process, the egg masses are easily scattered to other places due to their fragility and the instability of the soft brush, resulting in egg mass loss and affecting the accuracy of subsequent sample counts. Second, additional containers or tools are required to hold the egg masses, making the process cumbersome and reducing efficiency. Third, some egg masses are highly adhesive and difficult to brush off smoothly with a soft brush; forcibly brushing them may cause them to break, crush, or dry out, resulting in not only physical damage but also potentially affecting their biological activity and further sample loss. Fourth, the scales on the surface of the egg masses severely interfere with subsequent egg counting, leading to inaccurate counting results and affecting the reliability of research data.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for collecting eggs of the beet armyworm, comprising a collection tray base, a collection head storage box fixedly connected to one side surface of the collection tray base, a box cover fixedly connected to one side surface of the collection head storage box, a flexible egg-collecting head placed on the upper surface of the collection head storage box, a spray head fixedly connected to one side surface of the flexible egg-collecting head, an anti-slip grip fixedly connected to one side surface of the flexible egg-collecting head, a negative pressure adsorber fixedly connected to one side surface of the anti-slip grip, a water storage chamber fixedly connected to one side surface of the negative pressure adsorber, a collection tray mechanism provided on the upper surface of the collection tray base, and a miniature blower mechanism provided on the upper surface of the collection tray mechanism;

[0007] The collecting tray mechanism includes a scale storage chamber, a lower connecting tray, a rotating bead, an upper connecting tray, a limiting ring, a rotating ring, a storage sleeve, a fixing claw, and a silicone pad substrate.

A limiting ring is slidably connected to one side surface of the upper connecting tray. The rotating ring is fixedly connected to the upper surface of the upper connecting tray. The storage sleeve is fixedly connected to the upper surface of the rotating ring. The fixing claw is fixedly connected to the upper surface of the rotating ring. The silicone pad substrate is fixedly connected to the upper surface of the fixing claw.

[0008] Preferably, the collection tray base has three sets of equally spaced features on one side surface of the collection head storage box, and the outer surface of the anti-slip grip bar has multiple sets of anti-slip textures.

[0009] Preferably, twenty-four sets of connecting discs below the rotating ball are symmetrically arranged along the central axis, and the upper connecting disc and the lower connecting disc are sized to match and are slidably connected by a limiting ring.

[0010] Preferably, the outer surface of the rotating ring has multiple sets of anti-slip textures, and the inner side has a circular groove. The storage sleeve, fixing claw, and silicone pad substrate are symmetrically arranged in twelve sets around the central axis of the rotating ring.

[0011] Preferably, the rotating ring forms a sealed space with the upper micro blower through the storage sleeve, and the fixing claw has a total of six claw teeth, which are symmetrically arranged around the central axis of the silicone pad substrate.

[0012] Preferably, the miniature blower mechanism includes a connecting clip and a ring, an airflow distribution chamber, a chamber cover, an airflow adjustment chamber, an airflow adjustment button, a dust filter, a miniature motor, and fan blades.

[0013] Preferably, the inner surface of the airflow distribution chamber is provided with twelve air jets, which correspond to twelve storage sleeves, and the fan blades are arranged in three sets symmetrically around the central axis of the micro motor.

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

[0015] 1. Protecting the integrity of the egg mass: A flexible egg retrieval head is used in conjunction with a negative pressure adsorption device to collect the egg mass. This avoids the crushing, shriveling, or damage of the egg mass caused by unstable operation and uneven pressure, as is the case with a soft brush. This ensures the physical integrity and biological activity of the egg mass, providing a more reliable sample for subsequent research.

[0016] 2. Reduced egg mass stickiness for easier collection: The spray nozzle on the flexible egg collection head can spray a substance to reduce the stickiness of the egg mass to the host plant or gauze. Compared with the traditional method of forcibly brushing off egg masses that are difficult to remove with a soft brush, this device can collect egg masses more easily and reduce the loss of egg masses during the collection process.

[0017] 3. Cleaning scales and hair for easy counting: The micro blower has an adjustable airflow mechanism, which can effectively clean the scales and hair on the surface of the egg mass. The air jet in the airflow distribution chamber corresponds to the storage sleeve, which can accurately clean the scales and hair of each egg mass. The cleaned scales and hair fall into the scales and hair storage chamber, avoiding contamination of the experimental environment and ensuring the accuracy of subsequent egg mass counting.

[0018] 4. Reasonable design and easy operation: The three sets of collection tray bases increase the stability of the device; the anti-slip texture on the anti-slip handle and the anti-slip texture on the outside of the rotating ring make it easy for users to hold and rotate the collection tray, improving the convenience of operation; the reasonable design of the dimensions of each component, such as the number of rotating beads, the matching of connecting trays, and the setting of storage sleeves, ensures the smooth operation and practicality of the device.

[0027] 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.

[0028] Please see Figure 1-7This utility model provides a technical solution: a device for collecting eggs of the beet armyworm, including a collection tray base 1, a collection head storage box 2 fixedly connected to one side surface of the collection tray base 1, a box cover 3 fixedly connected to one side surface of the collection head storage box 2, a flexible egg-collecting head 4 placed on the upper surface of the collection head storage box 2, a spray head 5 fixedly connected to one side surface of the flexible egg-collecting head 4, an anti-slip grip 6 fixedly connected to one side surface of the flexible egg-collecting head 4, a negative pressure absorber 7 fixedly connected to one side surface of the anti-slip grip 6, a water storage chamber 8 fixedly connected to one side surface of the negative pressure absorber 7, a collection tray mechanism 9 provided on the upper surface of the collection tray base 1, and a micro blower mechanism 10 provided on the upper surface of the collection tray mechanism 9.

[0029] The collecting tray mechanism 9 includes a scale storage chamber 901, a lower connecting tray 902, a rotating bead 903, an upper connecting tray 904, a limiting ring 905, a rotating ring 906, a storage sleeve 907, a fixing claw 908, and a silicone pad substrate 909. The scale storage chamber 901 is fixedly connected to the upper surface of the collecting tray base 1. The lower connecting tray 902 is fixedly connected to the inner surface of the scale storage chamber 901. The rotating bead 903 is slidably connected to the upper surface of the lower connecting tray 902. The upper connecting tray 904 is slidably connected to the upper surface of the rotating bead 903. One side surface of the upper connecting tray 904 is slidably connected to... A limiting ring 905 is included. A rotating ring 906 is fixedly connected to the upper surface of the upper connecting plate 904. A storage sleeve 907 is fixedly connected to the upper surface of the rotating ring 906. A fixing claw 908 is fixedly connected to the upper surface of the rotating ring 906. A silicone pad substrate 909 is fixedly connected to the upper surface of the fixing claw 908. Through the arrangement of the scale storage chamber 901, lower connecting plate 902, rotating ball 903, upper connecting plate 904, limiting ring 905, rotating ring 906, storage sleeve 907, fixing claw 908, and silicone pad substrate 909, during use, the rotating ring is rotated... The anti-slip texture on the outer side of 906 allows for easy rotation of the storage module. Because the upper receiving plate 904 is dynamically connected to the lower receiving plate 902 via the rotating ball 903, the sliding friction during rotation is converted into rolling friction, reducing friction loss and extending the device's lifespan. The storage module can be rotated easily and stably without slipping, reducing operational difficulty and improving smoothness and convenience. The storage sleeve 907 and rotating ring 906 cooperate to form a closed structure with the lower surface of the airflow distribution chamber 1003, preparing the space for the scale removal process. Because the upper connecting plate 904 is slidably connected to the lower connecting plate 902 via the rotating ball 903, the rotating ring 906 and its connected storage sleeve 907, fixing claw 908, and other components can rotate flexibly. Operators can rotate different storage sleeves 907 to suitable positions as needed. For example, when collecting egg masses, an empty storage sleeve 907 can be rotated to the collection position. The storage sleeve 907 and the rotating ring 906 cooperate with each other to form a closed structure with the lower surface of the airflow distribution chamber 1002. This closed structure is crucial for the scale removal process. When the micro-blowing mechanism is working, the closed structure ensures that the airflow is concentrated on the surface of the egg masses inside the storage sleeve 907, improving airflow utilization and more effectively blowing off the scales from the egg masses and collecting them in the scale storage chamber 901, thus ensuring the effectiveness of scale removal.

[0030] Furthermore, the collection tray base 1 has three sets of equally spaced features on one side surface of the collection head storage box 2, and the outer surface of the anti-slip grip 6 has multiple sets of anti-slip textures. The anti-slip textures increase the friction between the hand and the grip 6 during use, making it more comfortable for the operator to hold. When the hand grips the anti-slip grip, the textures better conform to the contours of the fingers, reducing hand fatigue. Especially during long periods of egg mass collection, a comfortable grip can effectively improve the operator's work efficiency and prevent frequent changes in grip posture or interruptions in operation due to hand discomfort.

[0031] Furthermore, twenty-four sets of rotating beads are symmetrically arranged along the central axis of the connecting plate 902 below the rotating bead 903. The upper connecting plate 904 matches the size of the lower connecting plate 902 and is slidably connected by the limiting ring 905. Through the arrangement of the rotating beads 903 of the lower connecting plate 902, the upper connecting plate 904, and the limiting ring 905, the twenty-four sets of rotating beads are symmetrically distributed on the lower connecting plate 902 during use, which can evenly distribute the pressure to each rotating bead. Compared with a smaller number of rotating beads, more rotating beads can share a larger pressure, avoiding excessive local pressure that would lead to accelerated wear of components. The setting of the limiting ring 905 plays an axial limiting role for the upper connecting plate 904. It can prevent the upper connecting plate 904 from axially displacing during rotation, ensuring that the upper connecting plate 904 always maintains good contact and relative position with the lower connecting plate 902, avoiding component damage or functional failure caused by axial displacement.

[0032] Furthermore, the outer surface of the rotating ring 906 has multiple sets of anti-slip textures, and the inner surface has an annular groove. The storage sleeve 907, fixing claw 908, and silicone pad 909 are symmetrically arranged in twelve sets around the central axis of the rotating ring 906. Through the design of the rotating ring 906, the multiple sets of anti-slip textures on its outer surface greatly increase the friction between the user's hand and the rotating ring during use. In actual operation, the operator can grip the rotating ring 906 more firmly, preventing slippage. This makes the rotation operation easier and more precise. Whether adjusting the position of the storage sleeve 907 for egg collection or rotating the ring to clean scales in conjunction with a miniature blower, the operator can better control the angle and force of rotation, improving the convenience and efficiency of the operation.

[0033] Furthermore, the rotating ring 906 forms a sealed space with the micro-blowing mechanism 10 above through the storage sleeve 907. The fixing claw 908 has six claw teeth, which are symmetrically arranged around the central axis of the silicone pad substrate 909. Through the arrangement of the rotating ring 906 and the storage sleeve 907, when the micro-blowing mechanism 10 is started, the sealed space can effectively prevent airflow leakage. The airflow will be concentrated inside the storage sleeve 907, forming a relatively stable and strong wind environment. In this way, the airflow can act more efficiently on the surface of the egg mass, blowing off the scales attached to the egg mass, improving the utilization rate of the airflow, avoiding the problem of poor scale cleaning effect caused by airflow loss, and thus ensuring the efficient completion of scale cleaning work.

[0034] Furthermore, the miniature blower mechanism 10 includes a connecting clip and ring 1001, an airflow distribution chamber 1002, a chamber cover 1003, an airflow adjustment chamber 1004, an airflow adjustment button 1005, a dust filter 1006, a miniature motor 1007, and a fan blade 1008. The connecting clip and ring 1001 are slidably connected to the inner surface of the rotating ring 906, and the airflow distribution chamber 1002 is fixedly connected to one side surface of the connecting clip and ring 1001. The upper surface of the airflow distribution chamber 1002 is fixedly... A chamber cover 1003 is connected to the airflow regulating chamber 1004, which is fixedly connected to the upper surface of the chamber cover 1003. An airflow regulating button 1005 is fixedly connected to one side surface of the airflow regulating chamber 1004. A dustproof net 1006 is fixedly connected to the upper surface of the airflow regulating chamber 1004. A micro motor 1007 is fixedly connected to the lower surface of the dustproof net 1006. A fan blade 1008 is fixedly connected to the lower surface of the micro motor 1007. The airflow is controlled by a connecting clip and a ring 1001. The configuration of the distribution chamber 1002, chamber cover 1003, airflow regulating chamber 1004, airflow regulating button 1005, dustproof net 1006, micro motor 1007, and fan blade 1008 allows for the following process: During scale removal, the micro motor 1007 is activated, and the airflow is adjusted to a suitable level using the airflow regulating button 1005. The gas is evenly divided into airflows of equal pressure in the airflow distribution chamber 1002 and enters each chamber. The airflow blows off the scales on the egg mass, which then enters the scale storage chamber 901 for storage. The scale storage chamber 901 has four air holes on its outer side to allow for overall air circulation. This configuration allows the micro blower mechanism to adjust the airflow force, effectively cleaning the scales on the surface of the egg mass. The air jet of the airflow distribution chamber 901 corresponds to the storage sleeve, enabling precise scale removal for each egg mass. The cleaned scales fall into the scale storage chamber, avoiding contamination of the experimental environment and ensuring the accuracy of subsequent egg mass counting.

[0035] Furthermore, the inner surface of the airflow distribution chamber 1002 is provided with twelve jet nozzles, which correspond to the twelve storage sleeves 907. The fan blades 1008 are symmetrically arranged in three groups around the central axis of the micro motor 1007. Through the arrangement of the storage sleeves 907 and the airflow distribution chamber 1002, during use, the twelve jet nozzles correspond one-to-one with the twelve storage sleeves, which enables the airflow to act precisely on the surface of the egg mass in each storage sleeve. When the micro blower mechanism is activated, the airflow ejected from each jet nozzle can be directly aimed at the corresponding egg mass, ensuring that the scales on the surface of the egg mass can be blown by the airflow, thereby efficiently blowing the scales off the egg mass. This precise airflow action avoids the waste and dispersion of airflow and improves the effect and targeting of scale cleaning.

[0036] Working Principle: When using the Spodoptera litura egg mass collection device, firstly, the negative pressure adsorption system and spray system are activated to prepare for egg mass collection; then, the flexible egg-collecting head 4 is brought close to the egg mass, and the spray button is pressed to allow the spray head 5 to spray a small amount of separating agent, reducing the stickiness of the egg mass to the host plant or gauze, facilitating subsequent collection; then, the negative pressure adsorption function of the flexible egg-collecting head 4 is used to gently adsorb the egg mass; then, the flexible egg-collecting head 4 with the adsorbed egg mass is transferred to the rotating collection tray 9, the negative pressure is released, and the egg mass is gently placed into the corresponding grid on the collection tray 9. The fixing claws 908 and the silicone pad 909 of the collection tray 9 can stably fix the egg mass; then, the micro-blowing system is activated, and the micro motor 1007 drives the fan blades 1008 to rotate and generate airflow. After the airflow is evenly distributed through the airflow distribution chamber 1002, it flows from the storage... The twelve nozzles corresponding to the sleeve 907 spray precisely onto the surface of the egg mass, blowing off the scales. The blown-off scales enter the storage chamber 901 through the pores, preventing contamination of the experimental environment and ensuring accurate subsequent egg mass counting. After collecting and cleaning the scales of one egg mass, the anti-slip texture on the outside of the rotating ring 906 is rotated, and the rotating ball 903 converts sliding friction into rolling friction, easily rotating the collection tray 9 and moving the empty storage sleeve 907 to the collection position. The above operations of reducing viscosity, adsorbing egg masses, placing egg masses, and cleaning scales are repeated until all egg masses are collected. Finally, after the collection is completed, the scale collection box and spray system are cleaned to ensure the device is clean for future use. The entire process is efficient, convenient, and effectively protects the integrity of the egg masses, reducing interference with the experiment. The micro motor 1007 is model WL-37RS528.
