Description

Technical Field

[0001] This invention relates to the field of culture device technology, specifically a culture and observation device for corn leaf spot pathogen. Background Technology

[0002] Corn leaf blight pathogen is a major pathogen causing corn leaf spot disease. It mainly affects corn leaves, causing yellow-brown lesions. In severe cases, it can impair photosynthesis and lead to yield reduction. Its growth and reproduction are greatly affected by environmental factors such as temperature and humidity, and it thrives in warm, humid conditions. A corn leaf blight pathogen culture device is a specialized device used for the artificial cultivation of this pathogen. It typically includes culture containers, culture media, and components for controlling temperature, humidity, and light, providing a stable and suitable growth environment for the pathogen. This assists researchers in conducting experiments such as studying the biological characteristics of the pathogen and screening for disease-resistant varieties.

[0003] Chinese patent CN220555688U discloses a constant temperature sterile incubator. Addressing the problems mentioned in the background art regarding the susceptibility of samples to pathogenic bacteria infection and the difficulty in achieving constant temperature, the following solution is proposed: The incubator includes a chamber with evenly distributed ultraviolet lamps installed on one inner wall of the chamber, and a protective net installed on the inner wall of the chamber near the ultraviolet lamps. This solution uses ultraviolet irradiation to eliminate pathogens inside the chamber, preventing sample infection and improving sample survival rate. The constant temperature heating mechanism ensures the flow and uniformity of hot air, facilitating better temperature control. In the sample placement auxiliary mechanism, an upward lifting rod raises a transition plate, allowing samples to be placed on the transition plate before being placed into the chamber or during observation, providing a smooth transition and excellent auxiliary effect during the incubation process.

[0004] As described in the aforementioned patent, existing incubators typically require the use of ultraviolet disinfection modules and other sterilization components to pre-purify the air entering the chamber and control the microbial load within the chamber in order to prevent contamination of the target microorganisms in the culture dishes. However, during experimental operations, the incubator door needs to be opened frequently for tasks such as observing the culture status of the target microorganisms and adding or removing culture dishes. During the operation window when the door is open, unfiltered and unsterilized air from outside will directly enter the chamber, disrupting the established sterile environment and increasing the risk of contamination of the target microorganisms in the culture dishes. This seriously affects the stability and accuracy of the culture experiment results.

[0005] Therefore, it is necessary to provide a device for culturing and observing maize leaf spot pathogens to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a device for culturing and observing corn leaf spot pathogens. Through the coordinated arrangement of the internal drive system, mounting base and macro camera in the culture chamber, the device enables the observation of the growth of corn leaf spot pathogens in the culture dish without opening the chamber door.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a corn leaf spot pathogen cultivation and observation device, comprising an incubator, a door disposed on the incubator, an observation window disposed on the door, and a display panel disposed on the side wall of the incubator.

[0009] A further embodiment of the present invention is that the sealing assembly includes a mounting box, a sealing plate, and a driving assembly. Two mounting boxes, two sealing plates, and two driving assemblies are provided. The two mounting boxes are fixedly installed at the bottom positions on both sides of the mounting base. The two sealing plates are slidably installed in the two mounting boxes. The two sealing plates pass through the two opposite side walls of the mounting base and extend into the mounting groove. The driving assembly is provided on the mounting box to drive the sealing plates to move horizontally.

[0010] A further configuration of the present invention is as follows: the driving assembly includes a driving base, a fourth motor, and a fourth screw; the driving base is fixedly connected to the top wall of the sealing plate; the driving base is slidably connected to the mounting box; the fourth motor is fixedly mounted on the top wall of the mounting box; the output end of the fourth motor is fixedly connected to the end of the fourth screw; the fourth screw passes through the driving base and is threadedly connected to the driving base.

[0011] A further configuration of the present invention is as follows: the clamping assembly includes a connecting rod and an arc-shaped clamping plate, and two connecting rods and two arc-shaped clamping plates are provided. The top end of the connecting rod is fixedly connected to the bottom wall of the sealing plate, the connecting rod is slidably connected to the mounting box, and the bottom end of the connecting rod is fixedly connected to the arc-shaped clamping plate. The two arc-shaped clamping plates are symmetrically arranged.

[0012] A further feature of the present invention is that an anti-slip pad is fixedly installed on the inner side of the arc-shaped clamp, and a cover plate is fixedly installed at the top position of the inner side wall of the arc-shaped clamp. The cover plate is semi-circular. When the culture dish is clamped between the two arc-shaped clamps, the two cover plates fit together to close the top opening of the culture dish. When the two cover plates fit together, the two arc-shaped clamps also fit together.

[0013] A further configuration of the present invention is as follows: the placement assembly includes a placement cylinder and a support plate slidably disposed within the placement cylinder; the placement cylinder is disposed within a through hole; the top of the placement cylinder is open; an annular base plate is fixedly disposed at the bottom of the placement cylinder; an electric push rod is fixedly installed inside the base; a push block is fixedly installed at the output end of the electric push rod; the push block is located directly below the through hole; and a handle is fixedly installed on the side wall of the placement cylinder.

[0014] A further feature of the present invention is that: both sides of the placement cylinder are provided with sliding grooves, both sides of the support plate are fixedly installed with sliders, the two sliders are respectively slidably installed in the two sliding grooves, and a stop block is fixedly provided at the top of the sliding groove.

[0015] A further provision of the present invention is that: a sealing plate for sealing the top opening of the through hole is provided at the bottom of the inner cavity of the culture chamber, and a driving element for driving the sealing plate to move horizontally is provided inside the incubator.

[0016] A further configuration of the present invention is as follows: the driving system includes an X-axis driving mechanism, a Y-axis driving mechanism, and a Z-axis driving mechanism, all of which are disposed within the culture chamber, and the mounting base is disposed on the Y-axis driving mechanism.

[0017] In summary, the present invention has the following beneficial effects: Through the coordinated arrangement of the internal drive system, mounting base, and macro camera within the culture chamber, the present invention enables the observation of the growth of *Sclerotium cristatum* in a petri dish without opening the chamber door. The drive system can precisely move the mounting base along the X, Y, and Z directions, allowing the macro camera to be positioned directly above any target petri dish. The captured images are displayed in real-time on the display panel, effectively avoiding the problem of unfiltered and sterilized air entering the culture chamber due to opening the chamber door in traditional observation methods. This prevents the destruction of the established sterile environment within the culture chamber, significantly reducing the risk of contamination of the target pathogen within the petri dish and ensuring the stability and accuracy of the culture experiment. Simultaneously, the groove design in the middle of the placement rack allows the Y-axis drive mechanism of the drive system to pass through the groove, enabling the clamping components and the macro camera to share the same drive system, reducing the number of drive components and thus lowering equipment production costs. This invention constructs a transfer space for petri dish placement and retrieval through the coordinated arrangement of through holes on the base, access channels, a sealing door, and a placement component. This further prevents outside air from entering the culture chamber. When removing a petri dish, the drive system moves the clamping component to transfer the target petri dish above the through hole and place it inside the placement component. The operator only needs to open the sealing door and retrieve the placement component through the access channel. When replenishing petri dishes, after placing the petri dish containing pathogens into the placement component, it is pushed into the through hole through the access channel and then transferred by the clamping component to the placement rack inside the culture chamber. The entire process does not require opening the chamber door. At the same time, the design of the electric push rod, push block, and support plate in the placement component enables the stacking and convenient retrieval of multiple petri dishes, thereby improving the efficiency of petri dish placement and retrieval.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Please see Figures 1 to 7In this embodiment of the invention, a corn leaf spot pathogen cultivation and observation device includes an incubator 1, a door 102 disposed on the incubator 1, an observation window 103 disposed on the door 102, and a display panel 11 disposed on the side wall of the incubator 1. The incubator 1 has an internal cultivation chamber, and multiple placement racks 3 are disposed inside the cultivation chamber. The placement racks 3 are horizontally arranged and equidistantly distributed. A gap is provided between the side wall of the placement rack 3 away from the door 102 and the inner side wall of the incubator 1. A groove 302 is provided in the middle of each placement rack 3, and multiple positioning slots 301 are provided on the top of each placement rack 3. A mounting base 7 is disposed inside the cultivation chamber, and a macro camera 8 is embedded in the mounting base 7. The macro camera 8 is signal-connected to the display panel 11. A drive system for moving the mounting base 7 is provided inside the cultivation chamber. Below the mounting base 7, a clamping component 10 for holding the culture dish is provided. The bottom of the incubator 1 is provided with a base 101. The base 101 has a through hole 105 communicating with the inner cavity of the incubator 1. The front wall of the base 101 has an access channel 104 communicating with the through hole 105. A sealing door 20 is provided at the opening of the access channel 104. A placement component for placing the culture dish is provided inside the through hole 105. It should be noted that the incubator 1 is provided with necessary components for maintaining the microbial survival environment, such as a light system, a ventilation system, and a disinfection system. All of the above systems are existing technologies and will not be described in detail here. The groove 302 allows the Y-axis drive mechanism 6 of the drive system to move up and down through the groove 302. The movement of the clamping component 10 and the macro camera 8 shares a single drive system, which effectively reduces the production cost of the equipment. In practical use, first open the chamber door 102, and place the culture dishes containing corn leaf spot pathogens and culture medium into the positioning slots 301 on the placement rack 3. After all culture dishes are placed, close the chamber door 102 for cultivation. When it is necessary to observe the growth of pathogens in the culture dishes, the drive system moves the mounting base 7 within the cultivation chamber, positioning it directly above the culture dish to be observed. Then, the macro camera 8 captures images of the pathogen growth in the culture dishes, and the images are displayed on the display panel 11. This allows for simple observation of pathogen growth without opening the chamber door 102, effectively preventing contamination of the pathogens when removing the culture dishes for observation. When it is necessary to remove some culture dishes, the drive system moves the mounting base 7 above the desired culture dish. The culture dish is then clamped by the clamping component 10 below the mounting base 7. After the culture dish is clamped, it is moved by the drive system to move it above the through hole 105. The culture dish is then placed in the placement component. Then the sealing door 20 is opened, and the placement component can be taken out through the access channel 104. When it is necessary to add culture dishes to the incubator 1, the culture dish is placed in the placement component, the sealing door 20 is opened, and the placement component is pushed into the through hole 105 through the access channel 104. The sealing door 20 is then closed, and the culture dish is clamped by the clamping component 10 and moved to the desired placement rack 3. This solution uses the through hole 105 and the access channel 104 as a transfer space, which can effectively prevent outside air from entering the culture chamber when storing and taking out culture dishes, and prevent the corn leaf spot fungus in the culture dish from being contaminated.

[0022] In this embodiment, preferably, the driving system includes an X-axis driving mechanism 5, a Y-axis driving mechanism 6, and a Z-axis driving mechanism 4. All three mechanisms are disposed within the culture chamber. The mounting base 7 is disposed on the Y-axis driving mechanism 6. The X-axis driving mechanism 5 includes a first guide rail 401, a first screw 402, a first slide block 403, and a first motor 404. The first guide rail 401 is fixedly mounted on the inner wall of the culture chamber and is vertically arranged. The first screw 402 is rotatably mounted inside the first guide rail 401, and the first slide block 403 is slidably mounted on the first guide rail 401. Internally, a first screw 402 passes through a first slide block 403 and is threadedly connected to the first slide block 403. A first motor 404 is fixedly mounted on the bottom end of a first guide rail 401, and the output end of the first motor 404 is fixedly connected to the bottom end of the first screw 402. The Y-axis drive mechanism 6 includes a second guide rail 501, a second screw 502, a second slide block 503, and a second motor 504. The second guide rail 501 is fixedly mounted on the first slide block 403 and is horizontally arranged. The second screw 502 is rotatably mounted inside the second guide rail 501, and the second slide block 503 is slidably mounted inside the second guide rail 501. The second screw 502 passes through the second slide block 503 and is threadedly connected to the second slide block 503. The second motor 504 is fixedly installed at the end of the second guide rail 501, and the output end of the second motor 504 is fixedly connected to the end of the second screw 502. The Z-axis drive mechanism 4 includes a third guide rail 601, a third screw (not shown in the figure), a third slide block 604, a transmission box 602, and a third motor 603. The transmission box 602 is fixedly installed on the second slide block 503. The end of the third guide rail 601 is fixedly connected to the transmission box 602. The third guide rail 601 is horizontally arranged, and the third guide rail 601 is connected to the second slide block 503. The guide rails 501 are perpendicular to each other. The third slide block 604 is slidably installed inside the third guide rail 601. The third screw is rotatably installed inside the third guide rail 601. The third screw passes through the third slide block 604 and is threadedly connected to the third slide block 604. The mounting base 7 is fixedly installed on the bottom wall of the third slide block 604. The third motor 603 is fixedly installed on the transmission box 602. Two meshing gears (not shown in the figure) are rotatably installed inside the transmission box 602. The output end of the third motor 603 is fixedly connected to one of the gears. One end of the third screw extends into the transmission box 602 and is fixedly connected to the other gear. The X-axis drive mechanism 5, Y-axis drive mechanism 6, and Z-axis drive mechanism 4 enable the mounting base 7 to move along the X, Y, and Z axes. The X-axis drive mechanism 5 operates by using a first motor 404 to drive a first screw 402 to rotate, which in turn drives the first slide block 403 to move along the Z-axis. The Y-axis drive mechanism 6 operates by using a second motor 504 to drive a second screw 502 to rotate, which in turn drives the second slide block 503 to move along the Y-axis. The Z-axis drive mechanism 4 operates by using a third motor 603 to drive a third screw through two gears, which in turn drives the third slide block 604 to move along the X-axis. This drives the mounting base 7 to move, which in turn drives the macro camera 8 and the clamping assembly 10 to move. When controlling the mounting base 7 to move up and down through the placement frame 3, the third guide rail 601 needs to be moved to the center position first, so that the third guide rail 601 passes through the groove 302 on the placement frame 3. It should be noted that the first motor 404, the second motor 504 and the third motor 603 are all servo motors and are all connected to the control module in the display panel 11, so that the display panel 11 can control the first motor 404, the second motor 504 and the third motor 603 to work, thereby precisely controlling the movement of the mounting base 7.

[0023] In this embodiment, preferably, the culture chamber is provided with multiple sets of support seats 2, each set including two support seats 2, and the two support seats 2 in the same set are symmetrically arranged. The placement rack 3 can be detachably installed on the two support seats 2. The connection between the placement rack 3 and the support seats 2 can be achieved by plugging, snapping, magnetic connection or other connection methods.

[0024] Please see Figures 3-5In this embodiment of the invention, the bottom of the mounting base 7 is provided with a mounting groove, and the macro camera 8 is embedded in the mounting groove. The bottom of the mounting groove is open, and the two sides of the mounting base 7 are provided with sealing components 9 for sealing the bottom opening of the mounting groove. The sealing component 9 includes a mounting box 901, a sealing plate 902, and a driving component. There are two mounting boxes 901, two sealing plates 902, and two driving components. The two mounting boxes 901 are fixedly installed at the bottom positions on both sides of the mounting base 7. The two sealing plates 902 are slidably installed in the two mounting boxes 901. The two sealing plates 902 penetrate the two opposite side walls of the mounting base 7 and extend into the mounting groove. The driving component is set on the mounting box 901 to drive the sealing plate 902 to move horizontally. The driving component includes a driving base 903, a fourth motor 905, and a fourth screw 904. The driving base 903 and the sealing plate The top wall of the mounting box 901 is fixedly connected to the drive seat 903, which is slidably connected to the mounting box 901. The fourth motor 905 is fixedly installed on the top wall of the mounting box 901. The output end of the fourth motor 905 is fixedly connected to the end of the fourth screw 904. The fourth screw 904 passes through the drive seat 903 and is threadedly connected to the drive seat 903. When the macro camera 8 is not in use, the two sealing plates 902 close the bottom opening of the mounting slot to protect the macro camera 8. When the macro camera 8 needs to be used, the fourth motor 905 drives the fourth screw 904 to rotate. When the fourth screw 904 rotates, it drives the drive seat 903 to move horizontally. When the drive seat 903 moves horizontally, it drives the sealing plates 902 to move horizontally, so that the two sealing plates 902 move away from each other, thereby opening the bottom opening of the mounting slot, so that the macro camera 8 can take pictures.

[0025] In this embodiment, preferably, the clamping assembly 10 includes a connecting rod 1001 and an arc-shaped clamping plate 1002. Two connecting rods 1001 and two arc-shaped clamping plates 1002 are provided. The top end of the connecting rod 1001 is fixedly connected to the bottom wall of the sealing plate 902. The connecting rod 1001 is slidably connected to the mounting box 901. The bottom end of the connecting rod 1001 is fixedly connected to the arc-shaped clamping plate 1002. The two arc-shaped clamping plates 1002 are symmetrically arranged. An anti-slip pad 1003 is fixedly installed on the inner side of the arc-shaped clamping plate 1002. A cover plate 1004 is fixedly installed at the top position of the inner wall of the arc-shaped clamping plate 1002. The cover plate 1004 is semi-circular. When culture... When the petri dish is held between two arc-shaped clamping plates 1002, the two cover plates 1004 fit together to seal the top opening of the petri dish. When the two sealing plates 902 fit together, the two arc-shaped clamping plates 1002 also fit together. By fixing the connecting rod 1001 to the sealing plate 902, the arc-shaped clamping plate 1002 can also be moved by the connecting rod 1001 when the sealing plate 902 moves, thereby reducing the amount of driving components and reducing equipment costs. The semi-circular cover plate 1004 ensures that after the arc-shaped clamping plates 1002 hold the petri dish, the two cover plates 1004 can seal the top opening of the petri dish to prevent the culture medium inside the petri dish from splashing out when the petri dish moves.

[0026] Please see Figures 7-9 In this embodiment of the invention, the placement assembly includes a placement cylinder 13 and a support plate 15 slidably disposed within the placement cylinder 13. The placement cylinder 13 is disposed within a through hole 105, the inner diameter of which is similar to the outer diameter of the placement cylinder 13. When the placement cylinder 13 is inserted into the through hole 105, the placement cylinder 13 magnetically attracts the inner wall of the through hole 105 to fix the placement cylinder 13. The top of the placement cylinder 13 is open, and an annular base plate 18 is fixedly disposed at the bottom of the placement cylinder 13. An electric push rod 12 is fixedly installed inside the base 101, and a push block 19 is fixedly installed at the output end of the electric push rod 12. The outer diameter of the push block 19 is smaller than the inner diameter of the annular base plate 18, and the push block 19 is located within the through hole 105. Directly below, a handle 17 is fixedly installed on the side wall of the placement cylinder 13, which allows for convenient insertion and removal of the placement cylinder 13. When transferring the culture dish from the incubator 1 to the placement cylinder 13, the output end of the electric push rod 12 pushes the push block 19 upward. When the push block 19 moves upward, it passes through the annular bottom plate 18 and pushes the support plate 15 upward, so that the culture dish can be placed directly on the support plate 15. After placing one culture dish, the push block 19 is driven to move downward a certain distance, which is the same as the height of the culture dish. Then, the second culture dish can be stacked on top of the first culture dish, so that multiple culture dishes can be stacked in the placement cylinder 13 at the same time, thereby improving the efficiency of culture dish removal and insertion.

[0027] In this embodiment, preferably, a sealing plate 21 for sealing the top opening of the through hole 105 is provided at the bottom of the inner cavity of the culture chamber. A driving element (not shown in the figure) for driving the sealing plate 21 to move horizontally is provided in the incubator 1. The driving element can drive the sealing plate 21 to move horizontally, thereby closing the through hole 105. The driving element can be an electric push rod 12 or other driving components. When the sealing door 20 is opened, the top opening of the through hole 105 can be closed to completely isolate the outside air from entering the incubator 1. In order to further avoid the contamination of pathogens, an ultraviolet lamp is provided in the access channel 104 to disinfect the air in the access channel 104. Other conventional disinfection components can also be provided for disinfection.

[0028] In this embodiment, preferably, both sides of the placement cylinder 13 are provided with sliding grooves 1301, and both sides of the support plate 15 are fixedly installed with sliders 14. The two sliders 14 are respectively slidably installed in the two sliding grooves 1301. A stop block 16 is fixedly provided at the top of the sliding groove 1301 to limit the movement stroke of the slider 14. With the setting of the two sliding grooves 1301 and the sliders 14, when the culture dish in the placement cylinder 13 is taken out, the sliders 14 can be pushed upward to push the culture dish out one by one, so as to facilitate the removal of the culture dish.
