Description

Technical Field

[0001] The present invention relates to the field of biological laboratory equipment, and particularly relates to an extraction operation table for biological experiments. Background Art

[0002] A biological experiment operation table, also known as a biological safety cabinet or a laboratory fume hood, is a commonly used experimental equipment in modern laboratories. Generally, various biological experiment operations are carried out by using this equipment, such as cell culture, microbiological research, drug preparation, etc.

[0003] However, the existing operation tables for biological experiments mainly have the following defects: First, most of the existing operation tables for experiments are open-type. The open design will make the experimental process completely exposed. Although the operation is convenient in this way, the external environment will affect the experimental results. Especially for some biological experiments, microorganisms have relatively high requirements for temperature and environment, and it is easy to contaminate the experimental samples. Second, most of the existing equipment has an integral structure, which is not convenient for disassembly and assembly during transportation and transfer. Third, during the existing experimental process, generally, reagents are extracted and added manually. Especially in comparative experiments, it is impossible to ensure synchronous quantitative addition and extraction during the process of manual addition and extraction of reagents, which will make the experimental effect not ideal. Fourth, during the experimental process, it is generally necessary to shake the reaction test tube or glass bottle body to accelerate the reaction, so as to more intuitively observe the experimental results. However, currently, it is all manually shaken, which will pose a safety hazard, and the shaking frequency and amplitude will also affect the experimental results. Summary of the Invention

[0004] In order to solve the above defects, the present invention adopts the following technical solutions:

[0005] An extraction operation table for biological experiments, comprising a frame body, a mounting base plate, a disassembly cover, a constant temperature operation table, a cleaning pool, a test tube cabinet, a tool cabinet, an extraction mechanism, a vibration and extraction mechanism, and a controller. The mounting base plate is fixedly arranged on the upper part of the frame body. Installation grooves are opened on both sides of the mounting base plate. Fixed clamping plates are also arranged on both sides of the bottom of the disassembly cover. The clamping plates are installed in cooperation with the installation grooves. An operation window is movably installed at the front end of the disassembly cover. An operation space is formed between the disassembly cover and the mounting base plate. The constant temperature operation table, the test tube cabinet, and the tool cabinet are respectively arranged on the mounting base plate. A cleaning pool and a through hole are also opened on the mounting base plate. The through hole is communicated with the inside of the frame body and forms a storage cavity. The vibration and extraction mechanism is arranged in the storage cavity. The extraction mechanism is fixedly installed inside the disassembly cover. The controller is installed at the front end outside the disassembly cover, and the controller is respectively in signal connection with the extraction mechanism and the vibration and extraction mechanism.

[0006] Through the above technical solution, the operating table can be quickly assembled, replacing the existing overall machining of the experimental operating table, which has the problems of occupying a large space during transportation or being inconvenient to transfer. During the transfer process, the disassembly cover, the installation base plate and the frame can be directly disassembled. And during the experiment, the extraction mechanism can quantitatively extract the liquid in the test tube or other bottle bodies, replacing the traditional process of manually extracting or adding reagents by experimenters, without causing experimental errors, ensuring that the experimental process is more accurate. Secondly, the vibration extraction mechanism can automatically oscillate the test tube or other glass bottle bodies during some experiments that require shaking, replacing the traditional manual shaking process, reducing the safety hazards such as burns caused by the overflow of the reaction liquid.

[0007] Preferably, sealing silica gels are fixedly arranged at the edges where the installation grooves are in contact with the inner wall of the bottom of the disassembly cover. Threaded holes are opened in the installation grooves, and positioning round holes are also opened at the rear ends of the clamping plates. The axes of the threaded holes and the positioning round holes are on the same straight line.

[0008] Through the above technical solution, during the assembly process, the clamping plates on both sides of the bottom of the disassembly cover are inserted into the corresponding installation grooves, then the positioning round holes and the threaded holes are aligned, and then the clamping plates are fixed in the installation grooves by hexagon head screws or other screws. The disassembly process is the opposite. And the gaps are sealed by the sealing silica gel, which increases the sealing effect while ensuring that the disassembly cover does not shake.

[0009] Preferably, an annular liquid return groove is also opened on the installation base plate. A porous filter plate is fixedly arranged at the upper part of the annular liquid return groove and at the horizontal part of the installation base plate. The bottom of the annular liquid return groove is also communicated with a waste liquid collection bucket through a pipeline. The waste liquid collection bucket is fixedly installed inside the frame and is located on one side of the storage cavity. A coil pipe is also serpentinely distributed inside the constant temperature operating table. Both ends of the coil pipe are respectively connected to a heat exchanger to form a closed loop. The heat exchanger is installed inside the frame and is signal-connected to the controller.

[0010] Through the above technical solution, the annular liquid return groove can collect the reaction liquid spilled during the experiment and store it separately through the waste liquid collection bucket. Secondly, the controller can control the temperature of the liquid in the heat exchanger. In this way, the heat exchanger can keep the constant temperature operating table at a constant temperature or a stable temperature through the coil pipe, ensuring the temperature requirements for cell tissues or microbial reactions during the biological experiment, replacing the traditional temperature control method through air, directly acting on the constant temperature operating table, improving the experimental efficiency, and the temperature control is more accurate and effective.

[0011] Preferably, side windows are provided on both sides of the disassembly cover. Transparent glass is provided in both the side windows and the operation window. A handle is provided at the bottom of the front end of the operation window. An air inlet pipe is fixedly connected to one side of the disassembly cover. The other end of the air inlet pipe extends into the disassembly cover and is connected to the air purifier. The air purifier is fixedly installed on the top plate. The top plate is fixedly installed inside the disassembly cover and is parallel to the top surface of the disassembly cover. A plurality of air inlets are provided on the top plate. Filter nets are provided in the air inlets. A plurality of lamp tubes are fixedly provided on the bottom surface of the top plate. And the top plate is located above the extraction mechanism.

[0012] Through the above technical solution, the side windows not only reduce the weight of the disassembly cover, but also enable the internal experimental process to be observed through the transparent glass. The air inlet pipe is directly connected to the air supply system, and the air is purified by the air purifier to prevent untreated air from directly entering during the experiment. And the filter net can adsorb and filter harmful substances such as waste gas generated during the experiment during the return air process, avoiding the entry of harmful gases generated during the experiment into the atmosphere.

[0013] Preferably, the extraction mechanism includes tracks, track self-propelled vehicles, lead screws, extraction controllers, positioning probes, first motors, first electric cylinders, extraction seats, electric suction pumps, solenoid valves, suction pipes and extractors. The tracks are symmetrically installed on the front and rear inner walls of the disassembly cover. Track self-propelled vehicles are movably installed on the tracks. And the two track self-propelled vehicles are fixedly connected by two vertically arranged lead screws. The extraction controller is movably installed between the two lead screws. And a first motor is fixedly provided on the top of the extraction controller. A first electric cylinder is also movably provided in the middle of the extraction controller. The output end of the first motor is fixedly connected to the base of the first electric cylinder. The telescopic end of the first electric cylinder fixedly holds the extraction seat. A plurality of extractors are provided on the extraction seat. A plurality of electric suction pumps are also provided on the extraction seat. Each electric suction pump is connected to the corresponding extractor through a suction pipe. A solenoid valve is also provided on the suction pipe. The track self-propelled vehicle, extraction controller, positioning probe, first motor, first electric cylinder, electric suction pump and solenoid valve are all signal-connected to the controller.

[0014] Through the above technical solution, it replaces the traditional process of manual extraction or adding reagents. Traditional manual operation cannot precisely control the extraction or addition dosage. With the extraction mechanism, when it is necessary to add a specified dosage of reagent, only the actual dosage needs to be input to the controller through the control panel. The controller will drive the track self-propelled device to reach the specified position, and then move the extraction controller above the instrument. Then the controller drives the first electric cylinder to move downwards, so that the extractor extends into instruments such as test tubes. Then the electric suction pump adjusts the stroke according to the dosage and sucks the reagent into the extractor. This process can precisely control the dosage, and during the comparative experiment process, it can synchronously control the addition timing. Compared with the traditional comparative experiment process, through this extraction mechanism, it avoids experimental errors caused by asynchronous addition or unequal addition dosage.

[0015] Preferably, a water pipe is fixedly arranged on one side of the cleaning pool, and the other end of the water pipe is connected to a water pump. The water pump is fixedly installed inside the frame body. The bottom of the cleaning pool is also connected to a filter through a collecting pipe. Guide rails are also arranged on both sides of the upper edge of the through hole, and a cover plate is slidably installed between the guide rails.

[0016] Through the above technical solution, the experimental utensils can be cleaned after the experiment. The liquid generated during the cleaning process is filtered through the filter to prevent direct discharge into the sewer pipe and cause pollution. When it is not necessary to shake to accelerate the reaction process, the vibration and extraction mechanism is located inside the storage cavity. The cover plate can prevent impurities and other substances from entering. When needed, it is directly controlled to extend, and then bottles such as test tubes are placed on the vibration and extraction mechanism to shake and accelerate the reaction process, without the need to take out the test tubes separately, thus avoiding air or environmental cross-contamination.

[0017] Preferably, the vibration and extraction mechanism includes an oscillation component and an extraction component. The extraction component is movably installed on the top of the oscillation component. The oscillation component includes a lifting cylinder, a box body, a second motor, a speed reducer, a support rod, a rotating shaft, a rotating disk, a convex block, a top rod, a roller, a box cover, a spring, and an oscillation plate. The lifting cylinder is fixed at the bottom of the storage cavity, and the telescopic end of the lifting cylinder is fixedly connected to the bottom of the box body. The speed reducer is fixedly installed inside the box body, one side of the speed reducer is connected to the second motor, the output end of the speed reducer is connected to the rotating shaft, the top of the rotating shaft is fixedly connected to the rotating disk, several support rods are also installed inside the box body, and the top of each support rod is in sliding contact with the bottom surface of the rotating disk. Several convex blocks are also circumferentially arranged on the upper end surface of the rotating disk. A box cover is also arranged on the box body. Several top rods are circumferentially arranged at the bottom of the oscillation plate, rollers are fixedly arranged at the bottom of the top rods, and the top rods all pass through the box cover. Springs are also wrapped outside the top rods, the springs are located between the box cover and the oscillation plate, and both ends of the springs are fixedly connected to the box cover and the oscillation plate respectively.

[0018] Through the above technical solution, the oscillation component mainly generates oscillations. When shaking is required, only need to fix the test tube or bottle body on the extraction component, then start the controller, the second motor drives the reducer to rotate, so that the rotating disk rotates. During the rotation of the rotating disk, the bump also rotates accordingly. When the bump contacts the roller, the ejector rod will move upward. When the bump moves away from the roller, the ejector rod moves downward. In this way, the ejector rod drives the oscillation plate to reciprocate up and down. The spring mainly plays a role of returning to the original position, thus generating an oscillation effect.

[0019] Preferably, the extraction component includes a disk, a fastening component, a support column, a top cover, a connecting component, a movable plate, a limiting rod, a straight slot, an upper connecting block, a lower connecting block, a connecting column, a movable clamping plate, a support seat and a protective pad. The disk is movably installed in the middle of the upper part of the oscillation plate, and the fastening component is symmetrically arranged on the oscillation plate. The bottom of the support column is fixedly connected to the disk, and the top of the support column is fixedly connected to the top cover. Connecting components are fixedly connected to the four corners of the bottom of the top cover. A movable plate is movably installed between every two adjacent connecting components. Limiting rods are fixedly arranged on both sides of the movable plate. A straight slot is opened on the movable plate, and an upper connecting block and a lower connecting block are fixedly arranged above and below the straight slot respectively. A connecting column is fixedly connected between the upper connecting block and the lower connecting block. A movable clamping plate is movably installed on the connecting column. A clamping opening is opened at the front end of the movable clamping plate. One end of the movable clamping plate extends into the straight slot. The support seat is fixedly installed on the movable plate and is located below the lower connecting block. A protective pad is also arranged on the support seat.

[0020] Through the above technical solution, the disk can rotate on the oscillation plate, which is convenient for adjusting the installation surface when installing the test tube or bottle body. First, place the bottom of the test tube or bottle body on the protective pad on the support seat, and then manually adjust the position of the movable clamping plate. During the adjustment process, mainly to fix the test tube or bottle body to prevent it from detaching from the extraction component during oscillation.

[0021] Preferably, the fastening component includes an arc-shaped clamping block, a fixed seat and a fastening screw. The fixed seat is fixed on the oscillation plate. The fastening screw is movably installed on the fixed seat. One end of the fastening screw is movably connected to the arc-shaped clamping block. The inner side of the arc-shaped clamping block faces the outer edge of the disk. When installing the test tube or bottle body, the fastening component is not locked, which is convenient for rotating and installing the test tube to different working surfaces. After installation, whether to lock the disk can be manually controlled according to needs. The connecting component includes a first connecting plate, a second connecting plate and an arc-shaped chute. The first connecting plate and the second connecting plate are fixedly connected and are located below the top cover. The included angle between the first connecting plate and the second connecting plate is 90 degrees.

[0022] Preferably, an adjusting fixed block is also fixedly arranged on the inner side of the movable plate. An adjusting spring is fixedly arranged on the adjusting fixed block. The top of the adjusting spring is fixedly connected to one end of the movable clamping plate extending into the straight slot, and an elastic retaining ring is also arranged in the clamping opening.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. Through the installation groove on the installation base plate, it is convenient to disassemble and assemble the dismountable cover, which is beneficial for the transportation and transfer of the operation table. Secondly, the controller can perform real-time temperature control and adjustment on the constant-temperature operation table, ensuring that the experiment process will not be affected by temperature. In addition, this application can separately collect and treat the cleaning wastewater and chemical waste liquid generated during the experiment, avoiding pollution caused by direct discharge.

[0025] 2. Through the extraction mechanism, it is possible to quantitatively extract or add reagents to test tubes or other bottles. Especially during the comparative experiment process, under the control of the controller, each electric suction pump can synchronously and quantitatively add or extract reagents, replacing the traditional manual addition, which may cause the inability to synchronously and quantitatively add reagents to each reaction test tube, resulting in inaccurate experimental results. It can also synchronously control the dropping speed and dosage during addition.

[0026] 3. Through the vibration and lifting mechanism, it can replace the traditional manual shaking to accelerate the reaction process. Manually shaking is likely to cause test tubes and other glass bottles to fall during the shaking process, and the reaction reagents will splash, posing a safety hazard. Secondly, manual shaking cannot ensure a constant oscillation frequency. By separating and contacting the convex block and the ejector rod to cause a vibration effect, the vibration frequency can be controlled by the rotation speed of the first motor, ensuring that the shaking frequency always remains constant, and while ensuring the acceleration of the reaction, it will not cause a large deviation in the reaction effect.

The temperature control of the constant temperature operation table 4 can be adjusted according to the actual situation and is generally set to a constant temperature during the experiment. A cleaning pool 5 and a through hole 14 are also opened on the mounting base plate 2. The through hole 14 is communicated with the inside of the frame body 1 and forms a storage cavity 15. The vibration extraction mechanism 9 is arranged in the storage cavity 15. When not needed, the vibration extraction mechanism 9 will be located in the storage cavity 15. The extraction mechanism 8 is fixedly installed inside the dismounting cover 3 and can move back and forth, left and right. The controller 10 is installed at the front end outside the dismounting cover 3, and the controller 10 is respectively in signal connection with the extraction mechanism 8 and the vibration extraction mechanism 9.

[0044] Sealing silica gels 16 are fixedly arranged at the edges where the installation grooves 11 are in contact with the inner wall of the bottom of the disassembly cover 3. Threaded holes 17 are provided in the installation grooves 11. Positioning round holes 18 are also provided at the rear ends of the clamping plates 12.

[0045] During the transportation process, the disassembly cover 3, the installation base plate 2 and the frame body 1 can be directly disassembled. And during the experiment process, the liquid in the test tube or other bottle bodies can be quantitatively extracted through the extraction mechanism 8, replacing the traditional process of manually extracting reagents by experimenters. Here, addition can also be realized, that is, different reagents can be quantitatively transferred to the required test tubes for experiments, without causing experimental errors, ensuring that the experimental process is more accurate. Secondly, the vibration and extraction mechanism 9 can automatically oscillate the test tube or other glass bottle bodies during some experiments that require shaking, replacing the traditional manual hand-held shaking process, reducing the safety hazards such as the overflow of the reaction liquid and causing burns.

Coils 22 are serpentinely distributed inside the constant temperature operating table 4. The two ends of the coils 22 are respectively connected to a heat exchanger 23 to form a closed loop. The heat exchanger 23 is installed inside the frame body 1 and is signal-connected to the controller 10. The annular liquid return groove 19 can collect the reaction liquid spilled during the experiment process and store it separately through the waste liquid collection bucket 21. Secondly, the controller 10 can control the temperature of the liquid in the heat exchanger 23. In this way, the heat exchanger 23 can keep the constant temperature operating table 4 at a constant temperature or a required temperature through the coils 22, ensuring the temperature requirements for cell tissues or microbial reactions during the biological experiment process, replacing the traditional method of controlling the temperature through air, directly acting on the constant temperature operating table 4, improving the experimental efficiency, and making the temperature control more accurate and effective.

[0047] Refer to Figure 1 、 Figure 5 and Figure 6, side windows 24 are opened on both sides of the disassembly cover 3. Transparent glasses are provided in both the side windows 24 and the operation window 13. A handle 25 is provided at the bottom of the front end of the operation window 13. An air inlet pipe 26 is fixedly connected to one side of the disassembly cover 3. The other end of the air inlet pipe 26 extends into the disassembly cover 3 and is connected to an air purifier 27. The air purifier 27 is fixedly installed on a top plate 28. The top plate 28 is fixedly installed inside the disassembly cover 3 and is parallel to the top surface of the disassembly cover 3. A plurality of air inlets 29 are also opened on the top plate 28. Filter nets 30 are provided in the air inlets 29. A plurality of lamp tubes 31 are fixedly provided on the bottom surface of the top plate 28. And the top plate 28 is located above the extraction mechanism 8. Opening the side windows 24 not only reduces the weight of the disassembly cover 3, but also enables the internal experiment process to be observed through the transparent glass. The air inlet pipe 26 is directly connected to the air supply system, and the air is purified by the air purifier 27 to prevent the untreated air from directly entering during the experiment process, thereby causing the reagent to deteriorate. And the filter nets 30 can adsorb and filter harmful substances such as waste gas generated during the experiment process during the air return process, avoiding the harmful gas generated during the experiment process from entering the atmosphere.

[0048] Refer to Figure 5 , Figure 6 and Figure 8, the extraction mechanism 8 includes a track 800, a track self-propeller 801, a lead screw 802, an extraction controller 803, a positioning probe 804, a first motor 805, a first electric cylinder 806, an extraction seat 807, an electric suction pump 808, a solenoid valve 809, a suction tube 810, and an extractor 811. The tracks 800 are symmetrically installed on the front and rear inner walls of the disassembly cover 3. The track self-propellers 801 are movably installed on the tracks 800, and the two track self-propellers 801 are fixedly connected by two lead screws 802. The extraction controller 803 is movably installed between the two lead screws 802. The extraction controller 803 can move on the lead screw 802 under the action of the internal execution mechanism. A first motor 805 is fixedly arranged on the top of the extraction controller 803. The first motor 805 can adjust the rotation angle, that is, during the process of moving forward, backward, left, and right, the extraction seat 807 can be rotated to facilitate the alignment of the extractor 811 with the test tube carrier. A first electric cylinder 806 is movably arranged in the middle of the extraction controller 803. The output end of the first motor 805 is fixedly connected to the base of the first electric cylinder 806. The telescopic end of the first electric cylinder 806 fixedly holds the extraction seat 807. A plurality of extractors 811 are arranged on the extraction seat 807. A plurality of electric suction pumps 808 are also arranged on the extraction seat 807. Each electric suction pump 808 is connected to the corresponding extractor 811 through a suction tube 810. A solenoid valve 809 is also arranged on the suction tube 810. The solenoid valve 809 can only perform extraction and reagent addition when it is opened. The positioning probe 804 is fixedly installed at the bottom of the extraction controller 803. The positioning probe 804 mainly plays the role of identification and positioning. The track self-propeller 801, the extraction controller 803, the positioning probe 804, the first motor 805, the first electric cylinder 806, the electric suction pump 808, and the solenoid valve 809 are all signal-connected to the controller 10.

[0049] Extraction and addition process: Before the experiment, the experimenter adds the corresponding reagents into the test tubes and arranges them on the test tube carrier. During the experiment, generally in a closed environment, automatic extraction is carried out through the controller 10. First, the controller 10 automatically identifies and locates the position of the test tube to be extracted according to the feedback information of the positioning probe 804. Then the track self-propeller 801 is started and moves along the track 800 to the upper part of the test tube. Then the extraction controller 803 moves horizontally along the lead screw 802. The purpose of horizontal movement is to further determine the position. Then the first electric cylinder 806 moves downward so that the bottom of the extractor 811 extends into the test tube. This process can extract multiple test tubes simultaneously. When extracting, the solenoid valve 809 is opened, and then under the action of the electric suction pump 808, the liquid in the test tube is synchronously and quantitatively sucked in, thus realizing the extraction of the reagent. When adding the reagent, it is exactly the opposite of the extraction process. Different reagents or the same reagent can be quantitatively and synchronously added into the test tube. This process replaces manual extraction and addition, not only saving time, but also making the operation process more accurate.

[0050] Refer to Figure 4 and Figure 5 One side of the cleaning tank 5 is also fixedly provided with a water pipe 32, the other end of the water pipe 32 is connected to a water pump 33, the water pump 33 is fixedly installed inside the frame 1, the bottom of the cleaning tank 5 is also connected to a filter 35 through a collection pipe 34, and guide rails 36 are also arranged on both sides of the upper edge of the through hole 14. A cover plate 37 is slidably installed between the guide rails 36. After the experiment, the experimental utensils are cleaned through the water pipe 32. The liquid generated during the cleaning process is filtered through the filter 35 to prevent direct discharge into the sewer pipe and cause pollution. The cover plate 37 can be opened or closed along the guide rails 36 at any time, so as to facilitate the protection of the vibration lifting mechanism 9 and prevent it from being exposed outside and allowing dust and other impurities to enter.

[0051] Refer to Figure 5 、 Figure 9 、 Figure 11 and Figure 12 The vibration lifting mechanism 9 includes an oscillation assembly 91 and an extraction assembly 92. The extraction assembly 92 is movably installed on the top of the oscillation assembly 91. The oscillation assembly 91 includes a lifting cylinder 910, a box body 911, a second motor 912, a speed reducer 913, a support rod 914, a rotating shaft 915, a rotating disk 916, a convex block 917, a top rod 918, a roller 919, a box cover 9190, a spring 9191 and an oscillation plate 9192. The lifting cylinder 910 is fixed at the bottom of the storage cavity 15, and the telescopic end of the lifting cylinder 910 is fixedly connected to the bottom of the box body 911. The speed reducer 913 is fixedly installed inside the box body 911, one side of the speed reducer 913 is connected to the second motor 912, and the output end of the speed reducer 913 is connected to the rotating shaft 915. The top of the rotating shaft 915 is fixedly connected to the rotating disk 916. A number of support rods 914 are also installed inside the box body 911, and the top of each support rod 914 is in sliding contact with the bottom surface of the rotating disk 916. A number of convex blocks 917 are circumferentially arranged on the upper end surface of the rotating disk 916. A box cover 9190 is also arranged on the box body 911. A number of top rods 918 are circumferentially arranged at the bottom of the oscillation plate 9192. The bottom of each top rod 918 is fixedly provided with a roller 919, and the top rods 918 all pass through the box cover 9190. The outside of the top rods 918 is also wrapped with a spring 9191. The spring 9191 is located between the box cover 9190 and the oscillation plate 9192, and both ends of the spring 9191 are fixedly connected to the box cover 9190 and the oscillation plate 9192 respectively.

[0052] The oscillation assembly 91 mainly generates oscillations. The extraction assembly 92 is mainly used to carry test tubes, and the extraction assembly 92 can rotate on the oscillation assembly 91. That is, during the experiment, the test tube or conical flask containing the reaction liquid can rotate while undergoing up-and-down oscillations. When shaking and rotation are required, simply fix the test tube or bottle body on the extraction assembly 92, then start the controller 10. The second motor 912 drives the reducer 913 to rotate, thereby causing the rotating disk 916 to rotate. During the rotation of the rotating disk 916, the convex block 917 also rotates accordingly. When the convex block 917 contacts the roller 919, the ejector rod 918 will move upward. When the convex block 917 moves away from the roller 919, that is, after the contact is released, the ejector rod 918 moves downward. In this way, the ejector rod 918 will drive the oscillation plate 9192 to reciprocate up and down. During up-and-down oscillations, due to the generated vibrations, the extraction assembly 92 will also rotate on the oscillation plate 9192. The spring 9191 mainly plays a role in returning to the original position. The extraction assembly 92 is movably arranged on the oscillation plate 9192, which is also convenient for carrying test tubes or other tools. Just rotate the whole body to carry them on different working surfaces of the extraction assembly 92.

[0053] The extraction assembly 92 includes a disk 920, a fastening assembly 921, a support column 922, a top cover 923, a connecting assembly 924, a movable plate 925, a limiting rod 926, a straight slot 927, an upper connecting block 928, a lower connecting block 929, a connecting column 9290, a movable clamping plate 9291, a support seat 9292 and a protective pad 9293. The disk 920 is movably installed in the middle of the upper part of the oscillation plate 9192, and the fastening assembly 921 is symmetrically arranged on the oscillation plate 9192. The fastening assembly 921 is the key to whether the disk 920 can rotate. When rotation is not required, it can be locked to prevent the disk 920 from rotating on the oscillation plate 9192. The bottom of the support column 922 is fixedly connected to the disk 920, and the top of the support column 922 is fixedly connected to the top cover 923. The connecting assembly 924 is fixedly connected to the four corners of the bottom of the top cover 923. The movable plate 925 is movably installed between every two adjacent connecting assemblies 924. The limiting rod 926 is fixedly arranged on both sides of the movable plate 925. The angle of the movable plate 925 can be adjusted through the connecting assembly 924. The straight slot 927 is opened on the movable plate 925, and the upper connecting block 928 and the lower connecting block 929 are fixedly arranged above and below the straight slot 927 respectively. The connecting column 9290 is fixedly connected between the upper connecting block 928 and the lower connecting block 929. The movable clamping plate 9291 is movably installed on the connecting column 9290. The front end of the movable clamping plate 9291 is provided with a clamping opening 39. One end of the movable clamping plate 9291 extends into the straight slot 927. The support seat 9292 is fixedly installed on the movable plate 925 and is located below the lower connecting block 929. The protective pad 9293 is also arranged on the support seat 9292.

[0054] Process of carrying test tubes or other bottles:

[0055] Before vibration extraction, the extraction and addition operations are completed by the extraction mechanism 8. The extraction mechanism 8 and the vibration extraction mechanism 9 can operate independently or cooperate with each other. When vibration is required, first, the bottom of the test tube or conical flask is brought into contact with the protective pad 9293 on the support seat 9292. Here, the conical flask is taken as an example. Then, the neck of the conical flask is inserted into the clamping opening 39. During this process, the movable clamping plate 9291 can be moved up and down at any time according to the diameter of the neck, so that the movable clamping plate 9291 can clamp the neck. Among them, the movable plate 925 can adjust the angle between two adjacent connecting components 924, that is, by sliding the limiting rod 926 in the arc-shaped chute 9242, so that the bottle body on the movable plate 925 can maintain different position forms, which can be in the vertical direction or in an inclined state. After the oscillation is over, generally, during the leaching process, reagents are added into the bottle body. When the reagents are leached, the state of the bottle body needs to be adjusted. If the whole is taken out for leaching, the liquid will become turbid during the movement. Secondly, when adding reaction reagents again, if they are added vertically, it will also cause turbidity. Therefore, when leaching after the oscillation is over, generally, the bottle body is slowly adjusted to make the bottle body tilt at a certain angle, so as to ensure that the added liquid can flow along the inner wall and will not splash the internal liquid like in the vertical state, resulting in the turbidity of the liquid inside the bottle body.

[0056] The fastening component 921 includes an arc-shaped clamping block 9210, a fixed seat 9211 and a fastening screw 9212. The fixed seat 9211 is fixed on the oscillation plate 9192. The fastening screw 9212 is movably installed on the fixed seat 9211. One end of the fastening screw 9212 is movably connected to the arc-shaped clamping block 9210. The inner side of the arc-shaped clamping block 9210 faces the outer edge of the disc 920. Through the fastening component 921, it can be controlled whether the disc 920 can rotate during the oscillation process. The connecting component 924 includes a first connecting plate 9240, a second connecting plate 9241 and an arc-shaped chute 9242. The first connecting plate 9240 and the second connecting plate 9241 are fixedly connected and are located below the top cover 923. The included angle between the first connecting plate 9240 and the second connecting plate 9241 is 90 degrees.

[0057] An adjusting and fixing block 40 is fixedly arranged on the inner side of the movable plate 925. An adjusting spring 41 is fixedly arranged on the adjusting and fixing block 40. The top of the adjusting spring 41 is fixedly connected with one end of a movable clamping plate 9291 extending into a straight groove opening 927. Before clamping the bottle body, generally, the clamping opening 39 is aligned with a suitable bottleneck according to the position. During this process, the movable clamping plate 9291 generally moves along the connecting column 9290, thus stretching the adjusting spring 41. After the bottleneck is located within the clamping opening 39, generally, under the action of the adjusting spring 41, the movable clamping plate 9291 moves downward. This process ensures the stability of the bottle body and prevents it from shaking. An elastic retaining ring 42 is also arranged within the clamping opening 39, and the elastic retaining ring 42 mainly serves to protect the bottle body.
