Description

Technical Field

[0001] This utility model relates to the field of morphological scanning equipment technology, and in particular to a morphological scanning device for pine wood nematodes. Background Technology

[0002] Pine wood nematode is a worm-like animal belonging to the genus *Umbrella* of the family Rhynchophyllaceae in the order Rhynchophyllaceae. It is worm-shaped with a slender body; a high labial region with significant constriction; a slender stylet with a slightly thickened base; an oval-shaped middle esophagus with clearly defined valves; slender, leaf-shaped esophageal glands covering the dorsal surface of the intestine; the female worm has a subconical tail with a broad, rounded end; the male worm has a tail resembling a bird's claw, curving ventrally; the larvae in diseased wood have an anterior body similar to the adult, but a darker, less defined posterior body with a subconical tail.

[0003] Nematodes, common organisms in soil and water, can reflect environmental quality through morphological changes. Morphological scanning allows monitoring of nematode morphological changes under different environmental conditions, thereby assessing the degree of environmental pollution and ecological health. Pine wood nematode primarily harms pine species such as black pine, red pine, and Masson pine, causing the entire host tree to rapidly wither and die. This disease spreads rapidly, is extremely difficult to control, seriously impacts ecological security, and severely disrupts the market for pine lumber and ornamental pine, becoming a significant factor affecting global economic trade. Morphological scanning ensures the capture of high-quality, high-resolution nematode images, enabling rapid detection of pine wood nematodes. The principle of nematode morphological scanning is primarily based on optical imaging, image processing, and computer vision technology. By acquiring and analyzing nematode image information, morphological characteristics of the nematodes are extracted.

[0004] However, in practical applications, the scanning range of the scanning equipment is usually expanded by adjusting the position of the stage. The traditional adjustment method often relies on turning the knob to adjust the position of the stage. This method is not only inefficient but also has limited flexibility, making it difficult to meet diverse usage needs. Secondly, after the eyepiece is installed, the disassembly process is cumbersome and inconvenient, which undoubtedly adds obstacles to the maintenance work of the staff. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art, such as the stage being inconvenient to adjust, thus reducing its flexibility of use, and the eyepiece being inconvenient to disassemble and maintain after installation, and to propose a morphological scanning device for pine wood nematodes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A morphological scanning device for pine wood nematodes includes a main body and an electric light source, a stage, and a fixed support fixedly mounted on the main body. The stage is located between the electric light source and the fixed support. An Abbe condenser lens is fixedly mounted on the bottom of the stage. The device also includes a specimen placement frame disposed on the stage, wherein the specimen placement frame is provided with a guide, and when the guide is activated, the specimen placement frame tends to move laterally or longitudinally along the stage. A camera and a display screen are fixedly mounted on the fixed support, with the display screen located above the camera. A positioning frame is mounted on the fixed support via an adjustment mechanism, and an objective lens is inserted into the positioning frame, with the objective lens located between the camera and the specimen placement frame.

[0008] For lateral adjustment of the specimen placement frame, preferably, the guide includes a limiting frame fixedly connected to the bottom of the specimen placement frame, and a gear is rotatably connected inside the limiting frame, wherein the bottom of the gear is engaged with a toothed plate that is slidably connected to the stage.

[0009] To further limit the lateral movement of the specimen placement frame, a U-shaped frame is fixedly connected to the toothed plate, and a groove is provided inside the U-shaped frame, with the limiting frame slidably connected inside the groove.

[0010] To further adjust the specimen placement frame longitudinally, a T-shaped groove is provided on the stage. The T-shaped groove is longitudinal, and a T-shaped block that is fixedly connected to the toothed plate is slidably connected in the T-shaped groove.

[0011] To improve the efficiency of objective lens maintenance by vertically adjusting the positioning frame, preferably, the adjusting component includes a lead screw threaded onto a fixed bracket, one end of which passes through the fixed bracket and is rotatably connected to the positioning frame.

[0012] To facilitate the rotation of the lead screw by the operator, a knob is fixedly connected to the end of the lead screw away from the positioning frame, and the knob is provided with an anti-slip groove.

[0013] To vertically limit the positioning frame, preferably, a sliding rod is fixedly installed on the fixed bracket, and a sliding sleeve that is fixedly connected to the positioning frame is slidably connected to the sliding rod.

[0014] To protect the scanning equipment from dust, preferably, a positioning frame is fixedly installed on the machine body, and a folding dust cover is fixedly installed on the positioning frame, with the folding dust cover located at the top of the display screen.

[0015] To facilitate the movement of the specimen placement frame by staff, preferably, levers are fixedly connected to both sides of the specimen placement frame.

[0016] To improve imaging results, preferably, a transparent glass is fixedly installed inside the specimen placement frame.

[0017] Compared with the prior art, this utility model provides a morphological scanning device for pine wood nematodes, which has the following beneficial effects:

[0018] 1. This pine wood nematode morphology scanning device, through the cooperation of a sliding rod and a sliding sleeve, can limit the positioning frame, thereby improving the stability of the vertical movement of the positioning frame;

[0019] 2. The pine wood nematode morphology scanning device uses a positioning frame and a folding dust cover. When the folding dust cover is unfolded and its bottom contacts the machine body, it can protect the scanning device and prevent dust from contaminating it.

[0020] The parts not covered in this device are the same as or can be implemented using existing technologies. This utility model guides the specimen placement frame through the guide component, which can improve the adjustment efficiency and flexibility of the specimen placement frame, thereby increasing the scanning and imaging range of nematodes. In addition, the vertical adjustment of the positioning frame is made by the adjustment component, which facilitates the replacement and maintenance of the objective lens by the staff.

Therefore, they should not be construed as limitations on this utility model.

[0030] Example:

[0031] Reference Figures 1-6 A morphological scanning device for pine wood nematodes includes a body 1 and an electric light source, a stage, and a fixed support fixedly mounted on the body 1. The stage is located between the electric light source and the fixed support. An Abbe condenser lens is fixedly mounted on the bottom of the stage. The device also includes a specimen placement frame 2, which is set on the stage. Both sides of the specimen placement frame 2 are fixedly connected to levers to facilitate adjustment by the operator. A transparent glass is fixedly installed in the inner cavity of the specimen placement frame 2 to facilitate the passage of the light source, thereby improving the scanning and imaging quality. The specimen placement frame 2 is equipped with a guide. When the guide is in operation, the specimen placement frame 2 tends to move laterally or longitudinally along the stage. The operator can move the specimen placement frame 2 by hand, which not only increases the flexibility of adjustment but also improves the adjustment efficiency. A camera 3 and a display screen 4 are fixedly mounted on the fixed support. The camera 3 is an MDX10 microscope camera, and the display screen 4 is located above the camera 3. A positioning frame 5 is installed on the fixed support through an adjustment mechanism. An objective lens 6 is inserted into the positioning frame 5 and is located between the camera 3 and the specimen placement frame 2.

[0032] Specifically, by guiding the specimen placement frame 2 with the guide component, the adjustment efficiency and flexibility of the specimen placement frame 2 can be improved, thereby increasing the scanning and imaging range of nematodes. Furthermore, by using the adjustment component to vertically adjust the positioning frame 5, it is convenient for staff to replace and maintain the objective lens 6.

[0033] The guide includes four limiting frames 7 fixedly connected to the bottom of the specimen placement frame 2. The inner cavity of the limiting frame 7 is rotatably connected to a gear 71 via a shaft pin. The bottom of the gear 71 is meshed with a toothed plate 72 that is slidably connected to the stage. A U-shaped frame 73 is fixedly connected to the toothed plate 72. A groove is provided in the U-shaped frame 73. The limiting frame 7 is slidably connected in the groove for lateral limiting of the specimen placement frame 2. A T-shaped groove is provided on the stage. The T-shaped groove is longitudinal and a T-shaped block is slidably connected in the T-shaped groove and fixedly connected to the toothed plate 72 for easy adjustment of the longitudinal position of the specimen placement frame 2.

[0034] Specifically, by setting up guide components, the staff can move the specimen placement frame 2 laterally, so that the gear 71 meshes and moves on the toothed plate 72, which can improve the stability of the movement of the specimen placement frame 2. At the same time, moving the specimen placement frame 2 longitudinally can adjust the longitudinal position of the container, thereby realizing multi-position scanning and imaging. Furthermore, the use of hand control to move the specimen placement frame 2 can improve its flexibility of use.

[0035] The adjusting component includes a lead screw 8 threaded onto a fixed bracket. One end of the lead screw 8 passes through the fixed bracket and is rotatably connected to the positioning frame 5. A knob is fixedly connected to the end of the lead screw 8 away from the positioning frame 5. The knob has an anti-slip groove to facilitate the operator's adjustment of the lead screw 8.

[0036] Specifically, by adjusting the screw 8, the positioning frame 5 moves the objective lens 6 downward, thereby increasing the distance between the objective lens 6 and the camera 3, which makes it easier for staff to replace and maintain the objective lens 6.

[0037] A sliding rod is fixedly installed on the fixed bracket, and a sliding sleeve that is fixedly connected to the positioning frame 5 is slidably connected to the sliding rod.

[0038] Specifically, the sliding rod and sliding sleeve work together to limit the positioning frame 5, thereby improving the stability of the vertical movement of the positioning frame 5.

[0039] A positioning frame 9 is fixedly installed on the main body 1, and a folding dust cover 10 is fixedly installed on the positioning frame 9. The folding dust cover 10 is located at the top of the display screen 4.

[0040] Specifically, by using the positioning frame 9 and the folding dust cover 10 together, the folding dust cover 10 is unfolded so that its bottom contacts the machine body 1, which can protect the scanning equipment and prevent dust from contaminating it.

[0041] Working principle: When performing morphological scanning on pine wood nematodes, a glass slide containing the nematode sample is placed stably on the specimen placement frame 2. Then, the electric light source is turned on. Through the precise cooperation between the electric light source and the Abbe condenser, the light is projected onto the nematode sample evenly and in a focused manner. In conjunction with the high-magnification magnification of the objective lens 6, the three-dimensional structure of the nematode sample is clearly presented in the microscopic field of view. At this time, the camera 3 starts high-precision scanning to capture every detail of the nematode sample and transmits the image data to the display screen 4 in real time, so as to present the morphological characteristics of the nematode in an intuitive and three-dimensional way.

[0042] When scanning pine wood nematodes at different locations on a glass slide, the operator holds a lever to move the specimen placement frame 2 laterally. As the specimen placement frame 2 moves laterally, it drives the gear 71 to mesh and move on the toothed plate 72, thus adjusting the glass slide laterally. At the same time, the operator holds the lever to move the specimen placement frame 2 back and forth, causing the toothed plate 72 to move longitudinally on the stage, thus adjusting the glass slide longitudinally. Using hand adjustment not only improves adjustment efficiency but also enhances the flexibility of the specimen placement frame 2.

[0043] When staff need to replace or maintain objective lens 6, they can rotate screw 8 to move objective lens 6 downward with positioning frame 5. After objective lens 6 moves downward to the designated position, the distance between camera 3 and objective lens 6 increases. At this time, staff can pull objective lens 6 out of the inner cavity of positioning frame 5 for disassembly, thereby improving the maintenance efficiency of staff.

[0044] After scanning is completed, the staff pulls the folding dust cover 10. After the folding dust cover 10 is unfolded, its bottom contacts the machine body 1, which can cover the scanning equipment inside, thereby protecting the scanning equipment from dust.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
