Description

TECHNICAL FIELD

[0001] The present application relates to the field of soil mite classification, in particular to a soil mite extractor capable of autonomously detecting species and quantity. BACKGROUND

[0002] Mites are a class of micro-arthropods widely existing in soil ecosystems, with characteristics of large quantity, diverse species and diverse ecological functions. They play an important role in organic matter decomposition, nutrient cycling, soil aggregate formation and pest population regulation through feeding, excretion and burrowing behaviors, thus having important value in the fields of agricultural production, forestry protection and ecological restoration. In recent years, with the popularization of green agriculture, biological control and sustainable soil management concept, the research and utilization of mites, especially predatory mites, have gradually become an important direction of agricultural pest control and biodiversity protection. The first step of soil mite research is efficient and complete extraction of mite specimens. Accurate acquisition of mite samples is not only the basis for community diversity analysis, functional group classification and ecological function evaluation, but also an important prerequisite for subsequent species identification, diversity investigation, community monitoring, molecular biology research and biological control technology development. Therefore, how to efficiently, non-destructively and repeatedly separate mites from complex soil matrix is a key technical bottleneck in the field of research and industrial application.

[0003] However, the existing extraction method has many shortcomings in practical application. This method is usually temporarily set up by an experimentalist using a wide-mouth funnel, a yellow light source bulb and a beaker containing alcohol, etc. independent instruments. Due to the lack of a standardized overall experimental equipment framework, the equipment readiness is generally low, which not only makes it difficult to unify the experimental conditions, but also brings significant safety hazards. The device is easily knocked over by external environmental interference during the experiment, affecting the safety and reliability of the extraction process. More importantly, the extraction efficiency of this method is low, and the bottleneck is mainly reflected in the subsequent steps of sample processing. After the long extraction process is completed, the experimentalist must place the collected samples under a microscope, spending a lot of time and effort to manually search, identify species and count. This process not only has high labor intensity and is prone to subjective errors, but also the experimentalist cannot make any real-time observation on the dynamic changes in the funnel during the entire extraction process, making the entire process an inefficient "black box" operation. SUMMARY

[0004] In view of the shortcomings of the prior art, the present application provides a soil mite extractor capable of autonomously detecting species and quantity, which solves the problem that the existing soil mite extraction method completely relies on manual microscopic identification and counting after extraction, resulting in low efficiency, inability to observe the process in real time and prone to errors.

[0022] Preferably, the insect-repelling lamp has a height-adjustable extension structure mounting base, and the distance between the insect-repelling lamp and the soil in the extraction funnel is changed by adjusting the extension length of the mounting base to control the light intensity and heat intensity.

[0023] Preferably, the micro-object camera is mounted on a camera mounting bracket with a universal structure, and the angle and direction of the camera mounting bracket can be manually adjusted to accurately focus on the mites in the crawling channel.

[0024] Preferably, a mounting pin hole base is arranged below the display, and the pin hole base is connected with the pin hole base on the extractor bracket through a pin shaft to adjust the angle of the display screen.

[0025] Preferably, the soil mite extraction result displayed on the display includes two parts: the detection result including the species and quantity of mites output by the image processor, and the real-time video image output by the micro-object camera.

[0026] Working principle: first, place the soil sample in the extraction funnel, and turn on the insect-repelling lamp above the funnel, the light and heat generated by the insect-repelling lamp will use the biological characteristics of mites that like moisture, avoid light and heat to drive them to move downward, and finally separate from the soil and enter the closed crawling channel connected with the bottom of the funnel, when the mites unidirectionally crawl in the transparent crawling channel, the micro-object camera above the channel will capture the dynamic image in real time, and transmit the high-definition video stream data to the image processor, the image processor will call the built-in image detection algorithm trained by the mite image set to analyze the video stream in real time, automatically identify the species of the passing mites and count them, at the same time, the display will synchronously display the real-time picture taken by the micro-object camera and the statistical result of the species and quantity of mites analyzed by the image processor, realizing the visualization of the process, finally, the detected mites will continue to move along the crawling channel and fall into the alcohol collection dish at the end of the channel, and be effectively collected and preserved.

[0035] Embodiments:

[0036] Please refer to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application. Figure 1 - the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application. Figure 2 The embodiments of the present application provide a kind of self-detection kind and quantity of soil mite extractor, comprising:

[0037] extractor support 1;

[0038] extraction funnel 2, is set to the upper portion of extractor support 1, to hold the soil sample collected;

[0039] repellent lamp 6, is set to the upper portion of extraction funnel 2, to move down by light and heat to drive mite;

[0040] Crawling passage 3, one end is communicated with the lower portion of extraction funnel 2;

[0041] Alcohol collection dish 4, is connected with the other end of crawling passage 3, to collect mite;

[0042] Micro-object camera 5, is set to extractor support 1, to shoot inside crawling passage 3;

[0043] Image processor 8 is connected with micro-object camera 5, and built-in image detection algorithm is used to read video stream information and detect the kind and quantity of mite;

[0044] Display 7 is connected with image processor 8, to display detection result and real-time video image.

[0045] In this embodiment, the overall framework of the device is composed of an extractor support 1, which is preferably made of stable and light metal material, ensuring the stability of the whole device and the safety of operation, changing the traditional experiment of temporary construction and easy to knock down the security risks. The extraction funnel 2 is used to carry the soil samples to be treated, and its wide mouth design facilitates the rapid loading of samples. In order to guide the mites to move down smoothly, the inner wall of the funnel is treated with smoothness. The bottom of the funnel is connected with a specially designed crawling channel 3. Above the extraction funnel 2, a mite driving lamp 6 is erected, which is the driving force of the whole physical extraction process. It creates an unsuitable microenvironment for mites by continuously generating light and heat. Based on the biological characteristics of mites that they like moisture, avoid light and heat, the mites in the upper layer of soil will actively move to the deeper soil with lower temperature and higher humidity, and finally leave the soil from the bottom of the extraction funnel 2 and enter the crawling channel 3. The crawling channel 3 is a semicircular channel with a transparent glass plate completely closed at the top. This design has a double purpose: first, the closed structure can effectively prevent the escaped mites from escaping, ensuring the integrity of the collection; second, the transparent design at the top creates the necessary conditions for subsequent visual capture. After the mites enter the channel from the funnel, they will crawl along the preset path and finally reach the other end of the channel, which is connected to the alcohol collection dish 4. The pre-installed alcohol in the dish can quickly fix and preserve the crawling mites for subsequent possible review or in-depth study. Above the crawling channel 3, a micro-object camera 5 is fixedly installed through the support. The position and angle of the camera are carefully designed to clearly capture each mite individual crawling inside through the transparent top cover of the crawling channel 3 and transmit the dynamic process in the form of stable video stream in real time. The video stream data is sent to the image processor 8 electrically connected to the micro-object camera 5. The processor is deployed with an image detection algorithm trained by a large amount of mite image data. When the processor receives the real-time video stream, the algorithm will analyze the frame by frame, and once a mite target is detected, it will immediately identify its morphological characteristics to determine its species and count simultaneously. Finally, all the processing results and real-time pictures will be displayed on the display 7. Instead of waiting for the extraction to end and then observing under the microscope and manually counting as in the past, the experimenter can directly see the mites crawling through the channel and the real-time updated species identification results and cumulative number on the screen during the extraction process.

[0046] Please refer to the attached Figure 1 - attached Figure 2, the image detection algorithm built in the image processor 8 is developed based on the YOLO-V8 algorithm framework, trained using a set of mite images, and the image detection algorithm has a built-in counter to count and accumulate the detected mite species and quantity, the cross section of the crawling channel 3 is semicircular, and the upper part is closed with transparent glass to facilitate the shooting of the micro-object camera 5; the crawling channel 3 is divided into a vertical section connected with the extraction funnel 2, a curved section for adjusting the direction, and a straight section connected with the alcohol collection dish 4, to guide the one-way movement of the mites, the extractor support 1 has a three-layer structure, wherein:

[0047] The top device installation plane is used to install the pest-repellent lamp 6;

[0048] The middle device installation plane has a round hole matched with the extraction funnel 2, and is used to install the micro-object camera 5, the image processor 8 and the display 7;

[0049] The lowermost device installation plane is used to place the alcohol collection dish 4.

[0050] In this embodiment, the image processor 8 serves as the intelligent core of the device, and its capabilities are not derived from simple image comparison, but rather from an image detection algorithm based on deep learning. Specifically, this algorithm is preferably developed using the current mainstream and efficient YOLO-V8 algorithm framework. This framework is chosen because it can achieve good detection speed and accuracy when processing real-time video streams, which is crucial for dynamically capturing and identifying fast-moving tiny mites. To enable the algorithm to accurately identify mites, a large and diverse set of mite images is used to train it specifically. This process is equivalent to teaching the processor how to distinguish between different types of mites, such as their subtle differences in size, color, and appendages. The image detection algorithm also integrates a counter module. When a mite is successfully identified in the video stream, the counter automatically records the number based on its type. In this way, at the end of the entire extraction process, the experimenter can directly obtain a clear report on the types and quantities, thereby freeing researchers from the tedious and error-prone manual counting under a microscope. The cross-section of the crawling channel 3 is designed as a semi-circle rather than a full circle. This is because the flat bottom provides a stable crawling surface for mites, preventing them from rolling or moving irregularly within the channel. To allow the micro-object camera 5 to shoot without obstacles, the top of the channel is closed with transparent glass of high light transmittance. In addition, to effectively guide the travel route of mites and prevent them from flowing back or gathering in the channel, causing repeated counting or missing, the entire crawling channel 3 is ingeniously divided into three functional sections: first, the vertical section directly connected to the bottom of the extraction funnel 2, which receives the mites driven out of the soil; then a curved section, which serves to moderate the impact of the falling mites and smoothly adjust their direction to horizontal, most importantly, to ensure that mites move in one direction when entering the next stage; finally, a straight section of appropriate length, which is the main observation area, where mites move steadily, greatly reducing the difficulty of dynamic capture by the camera and identification by the algorithm. The end of this straight section is connected to the alcohol collection dish 4, constituting the endpoint of the mites' journey. The extractor support 1 adopts a logical three-layer structure design, with each layer carrying specific functions, making the entire extraction process orderly from top to bottom. Specifically: the topmost device installation plane, whose core function is to install the pest-repelling lamp 6, ensures that light and heat are evenly distributed over the soil sample in the extraction funnel 2 below, achieving optimal driving effect. The middle device installation plane is the operation core and data center of the entire device, with a precise circular hole in the center to securely hold the extraction funnel 2. Meanwhile, the lower surface of this plane provides a mounting point for the micro-object camera 5, and the upper surface integrates the image processor 8 and the display 7. This layout allows the operator to perform sample placement, process monitoring, and data reading in the same area, greatly improving work efficiency.The lowermost device installation plane provides a stable and independent placement platform for the alcohol collection tray 4, ensuring the safety and reliability of the sample collection process. This hierarchical integration design not only makes the device structure compact and regular in shape, but more importantly, ensures smooth and safe experimental procedures, completely solving the problem of accidental placement of instruments and equipment in traditional methods.

[0051] Please refer to the attached Figure 1 - attached Figure 2 The extraction funnel 2 is made of stainless steel and has a smooth inner surface. It has a hole below that matches the semi-circular cross-section of the crawling channel 3. They are fixed by welding. The alcohol collection tray 4 is made of glass and has a groove on the side wall that tightly fits the outer surface of the crawling channel 3. The inside of the groove is lined with a non-slip silicone strip to achieve airtight connection. The insect-repellent lamp 6 has a height-adjustable extension structure installation base. By adjusting the extension length of the installation base, the distance between the insect-repellent lamp 6 and the soil in the extraction funnel 2 can be changed to control the intensity of light and heat. The micro-object camera 5 is installed on a universal camera mounting bracket that can be manually adjusted in angle and direction to accurately focus on the mites in the crawling channel 3. The display 7 is equipped with a mounting pin hole base below. It is connected with the pin hole base on the extractor bracket 1 through a pin shaft to realize the adjustable angle of the display screen. The soil mite extraction results displayed on the display 7 include two parts: the detection results including the species and quantity of mites output by the image processor 8, and the real-time video image output by the micro-object camera 5.

[0052] The funnel is made of stainless steel with stable chemical properties and easy to clean. Its inner surface is finely smoothed to minimize the adhesion and retention of soil particles or mites on the funnel wall, ensuring that every tiny mite individual can smoothly slide to the bottom of the funnel by gravity and its own activity, thereby improving the transfer efficiency of the sample. In the lower part of the funnel, a hole is opened that perfectly matches the semi-circular cross-section of the crawling channel 3, and they are firmly and seamlessly connected by welding. This design ensures that there is no gap or step in the transition path of mites from the funnel to the crawling channel 3, forming a continuous and smooth guide surface, which structurally eliminates the possibility of mites being stranded or lost at the interface. The collection dish is preferably transparent glass material, which is convenient for the experimenter to observe the internal collection. Its sidewall is processed with a groove that precisely fits the outer surface profile of the crawling channel 3. This is not simply placed side by side, but a kind of embedded physical coupling, so that the end of the crawling channel 3 can be firmly embedded in the collection dish. In order to achieve perfect sealing effect, prevent mites from escaping at the last moment, and at the same time reduce the evaporation of alcohol in the dish, a circle of elastic anti-slip silicone strip is attached to the inside of the groove. When the crawling channel 3 is embedded, the silicone strip will be slightly squeezed, forming a flexible seal with the outer wall of the channel, ensuring that the mites crawling out of the channel can only fall into the alcohol. The repelling lamp 6 is installed on a stretchable mounting base with adjustable height, and the operator can accurately change the distance between the light source of the repelling lamp 6 and the soil surface in the extraction funnel 2 by simply adjusting the stretch length of the mounting base. This adjustment function is needed because different types of soil have different absorption and conduction capabilities for heat and light. By adjusting the distance, the intensity of light and heat applied to the soil sample can be directly controlled, so as to find an optimal driving force to drive mites, while avoiding the harm to the sample or the rapid water loss of the soil due to excessive temperature, greatly enhancing the applicability of the device and the reliability of the experimental results. The micro-object camera 5 is installed on a universal camera mounting bracket. This universal structure gives the camera multiple degrees of freedom adjustment capability, and the experimenter can manually and finely adjust its pitch, yaw, and front and back position. The core purpose is to accurately focus the camera lens on the small observation area inside the crawling channel 3. Since mites are small in size, any deviation of the focal point or improper angle of view may cause image blur, affecting the recognition accuracy of the subsequent algorithm. Through this universal bracket, the operator can easily obtain the best shooting angle and the clearest imaging effect, providing the most reliable visual information source for subsequent intelligent recognition and counting. The display 7 is equipped with a mounting pin hole base below, which can be connected with another pin hole base set on the middle layer plane of the extractor support 1 through a pin shaft.This pin-based connection forms a simple rotary joint, allowing the experimenter to swing the screen up and down easily, thus achieving free adjustment of the display screen angle. In a complex laboratory environment, the height, sitting or standing posture of the operator varies, and the ambient light may also cause glare on the screen. This adjustable design ensures that the operator can clearly observe the screen content at the most comfortable viewing angle under any conditions, improving the comfort and convenience of long-term monitoring. The soil mite extraction results displayed on the screen are not a single list of data, but contain two core parts, which are displayed on the same screen and complement each other. The first part is the structured data output by the image processor 8 after operation, which includes the detection results of mite species and quantity, providing the most intuitive quantitative information for the experimenter. The second part is the real-time video image from the micro-object camera 5. The significance of combining the two parts is to establish a transparent and reliable feedback loop: the operator can not only see the final statistical data, but also witness the process of each mite being captured and identified, and can at any time intuitively evaluate and confirm the running state of the system. This design greatly enhances the user's trust in the automated detection results.

[0053] While embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, combinations, and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, which is defined by the appended claims and their equivalents.
