Description

Technical Field

[0001] The invention relates to the technical field of geochemical analysis, and in particular to a portable geochemical analysis operating table. Background Art

[0002] In the process of geological exploration and mineral exploration, it is necessary to conduct chemical analysis on samples such as rocks, soils, and ores to obtain information such as their chemical composition and mineral composition. This information is crucial for determining geological structures, mineral deposit types, and mineral deposit scales. Traditional analysis methods require samples to be sent back to the laboratory, which is not only time-consuming but also costly. The emergence of portable geochemical analysis consoles makes it possible to conduct rapid and accurate chemical analysis on site, thereby greatly improving exploration efficiency and accuracy. In addition, in the field of environmental monitoring, rapid detection of pollutants such as soil, water quality, and air is an important means to protect the ecological environment. Portable geochemical analysis consoles can be carried to the site for real-time analysis of pollutants, providing a scientific basis for environmental protection decisions. In addition, during mining, it is also necessary to analyze and detect tailings, dust, soil pollution, etc. to evaluate the environmental remediation effect of the ore, and portable consoles can also meet these needs.

[0003] Most of the existing portable geochemical analysis workbenches use a support frame or a support shell as the main support platform, and then install components with multiple functions, such as work storage, reagent storage and placement platform. For geochemical analysis, most samples need to be pre-processed (grinding the sample particle diameter to a standard size) so that the subsequent analysis results have reference value. In addition, the working environment of most of these devices is in the field, so on-site sampling and analysis are carried out. Most of the existing devices are difficult to grind the samples to the standard particle size, and they are usually crushed manually, which is inefficient; although some devices are equipped with grinding mechanisms, the ground surface in the field environment is mostly uneven. When the device is fixed on these surfaces, there will be a certain inclination angle as a whole, so when grinding, the sample will gather in the inclined direction, making it difficult for the grinding mechanism to fully grind the sample, reducing the efficiency of the entire analysis process.

[0004] In summary, the present invention proposes a portable geochemical analysis operating table, which reduces the impact of uneven terrain in the field on the device, thereby improving the geochemical analysis efficiency of the device when working in the field. Summary of the invention

[0005] To solve the above problems, the present invention provides a portable geochemical analysis operating table, which reduces the impact of uneven terrain in the field on the device by swinging the sample table, while improving the grinding efficiency, thereby improving the geochemical analysis efficiency of the device when working in the field.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a portable geochemical analysis operating table, comprising a supporting shell, a functional box is installed inside the supporting shell, a rotating groove is opened on the top wall and the bottom wall of the supporting shell, a cylindrical slider is symmetrically provided on the top and the bottom of the functional box, respectively slidably matched with the rotating groove, and the cylindrical slider is close to one end of the width direction of the functional box, the top and the bottom of the functional box are symmetrically connected to the first connecting rod, and the other end of the first connecting rod is respectively connected to the top wall and the bottom wall of the supporting shell; the functional box is divided from left to right into a storage area for placing analysis tools and reagents and an operation area for geochemical analysis;

[0007] An operation panel hinged to the function box and a baffle located above the operation panel are provided in the operation area, a crushing chamber corresponding to the baffle is opened in the operation area, and a crushing assembly for crushing and pre-processing the sample to be analyzed is installed in the crushing chamber;

[0008] The crushing assembly includes a motor fixed in a crushing chamber, the motor output shaft is coaxially fixedly connected to a rotating disk, the rotating disk is eccentrically fixedly connected to a push rod on a side away from the motor and is coaxially fixedly connected to a second connecting rod, the other end of the second connecting rod is hinged to a third connecting rod, the other end of the third connecting rod is hinged to a moving rod, a crushing head is fixedly connected to the bottom of the moving rod and the moving rod is slidably matched with the inner wall of the crushing chamber, the push rod is slidably matched with a cam connecting rod, the inside of the crushing chamber is rotatably connected to a first rotating shaft rotatably matched with the cam connecting rod, the cam portion of the cam connecting rod is fixedly connected to a fourth connecting rod, a swing groove is opened on one side in the length direction of the sample table, and the swing groove is connected to the fourth connecting rod.

[0009] Principle of the basic solution: The rotating disk is driven by a motor to rotate, so that the push rod eccentrically arranged on the rotating disk slides along the through groove on the cam connecting rod, thereby causing the cam connecting rod and the fourth connecting rod to swing back and forth; when the fourth connecting rod swings, one end thereof slides along the swinging groove, causing the sample stage to swing accordingly around the hinge point with the base, causing the sample to be analyzed in the sample stage to shake and be fully crushed by the crushing head to improve efficiency. At the same time, by swinging back and forth, the possibility of the sample always gathering in the tilted direction when the device is placed tilted in the field is reduced.

[0010] The above scheme has the following beneficial effects:

[0011] 1. Compared with the existing technology, this solution realizes the automatic swing of the sample table through the design of motor drive and connecting rod mechanism, so that the sample to be analyzed can be ground more evenly during the crushing process, improving the grinding efficiency. In addition, considering the complexity of the field environment, especially the problem of uneven terrain, the swing function of the sample table can effectively reduce the phenomenon of sample gathering when the device is tilted, so that the operating table can maintain a high working efficiency under various terrain conditions, and improve the adaptability of the device.

[0012] 2. This solution divides the functional box into areas, namely, a storage area and an operation area, so as to facilitate quick access to storage and analysis tools.

[0013] Furthermore, a first drawer and a second drawer are provided in the storage area, and the first drawer is located below the second drawer.

[0014] Beneficial effects: By arranging the first drawer and the second drawer in layers, the space in the storage area can be used more effectively, so that different types of analytical tools, reagents or other necessities can be stored in categories, which is convenient for use and avoids confusion. In actual operation, geochemical analysts can quickly take out the required tools or reagents from the corresponding drawers as needed, which helps to reduce preparation time and thus improve the work efficiency of the entire analysis process. The design of layered drawers can also enhance the safety of items in the storage area to a certain extent. In particular, for reagents that may be dangerous or require special storage conditions, they can be placed in a safer drawer layer to reduce the risk of accidents.

[0015] Furthermore, a press-type buckle is installed on the top of the support shell, and a slot corresponding to the buckle is opened on the top of the function box.

[0016] Beneficial effects: The push-type buckle is combined with the card slot on the top of the function box to ensure the stability of the function box in the support shell. Whether in transportation or in field operations, it can effectively prevent the function box from moving due to vibration or external force, thereby protecting the internal analytical tools and reagents from damage. At the same time, the push-type buckle design allows users to easily lock and unlock the function box. Users only need to simply press the card operation buckle to quickly fix or release the function box without complicated or tool assistance, which not only improves work efficiency, but also reduces the user's operating burden and improves convenience.

[0017] Furthermore, a stabilizing component is installed inside the function box, and the stabilizing component includes a stabilizing cavity opened inside the function box. A support column is slidably fitted in the stabilizing cavity and the bottom end of the support column extends to the bottom end of the function box. The support column is slidably fitted with the function box, and a locking knob is threadedly connected to the surface of the function box. The support column is located within the movement trajectory of the locking knob.

[0018] Beneficial effects: The sliding cooperation between the support column and the function box, as well as the fixing effect of the locking knob on the support column, together constitute the core function of the stabilization component. In the complex and changeable terrain environment in the field, the user can adjust the extension length of the support column as needed, and fix it firmly in the desired position through the locking knob. In this way, no matter what angle the operating table is placed on the ground, the stabilization component can provide additional support force, effectively preventing the operating table from tilting or sliding, and ensuring the accuracy and safety of the analysis process.

[0019] In addition, the design of the support column and the locking knob enables the operating table to adapt to different terrains and tilt angles. The user only needs to simply adjust the extension length of the support column and rotate the locking knob to fix it, so that the operating table can be stably placed on different ground surfaces, which not only improves the practicality of the operating table, but also expands its application range. When the stabilizing component is not in use, the user can completely retract the support column into the stabilizing cavity and fix it with the locking knob, so that the overall volume and weight of the operating table are effectively controlled, making it easy to carry and store.

[0020] Furthermore, a protective cover is symmetrically slidably connected to the top of the sample stage along the length direction.

[0021] Beneficial effect: The design of the protective cover can keep the sample to be analyzed confined within the sample table during the crushing process, thereby improving crushing efficiency and safety. At the same time, the protective cover is slidably connected to the sample table, so that placing the sample in the sample table and taking out the crushed sample only requires sliding along the length direction of the sample table and taking out the two protective covers.

[0022] Furthermore, a handle is installed on the top of the supporting shell.

[0023] Beneficial effects: The installation of the handle makes the entire portable geochemical analysis operating table more convenient to carry and move. The user can easily move the operating table from one location to another by holding the handle, without the need to lift or drag it laboriously. At the same time, when the position or angle of the operating table needs to be adjusted, the handle can also play a supporting role. The user can easily rotate, tilt or translate the operating table by holding the handle to better adapt to different working environments and needs, which not only improves work efficiency, but also reduces errors and safety hazards caused by inconvenient operation.

[0024] Furthermore, the two cylindrical sliders are both rotatably connected to the function box, and the length of the first connecting rod is greater than the vertical distance between the two cylindrical sliders. The first connecting rod is provided with grooves corresponding to the cylindrical sliders.

[0025] Beneficial effects: The two cylindrical sliders are rotatably connected to the function box, and the length of the first connecting rod is greater than the vertical distance between the two cylindrical sliders. The first connecting rod is designed with grooves corresponding to the cylindrical sliders, so that the function box can complete a 180° rotation, greatly enhancing its flexibility. Users can easily rotate the function box to any desired angle (0-180°) as needed to better perform sample analysis, reagent extraction or other operations, which not only improves work efficiency, but also makes operation more convenient and comfortable.

[0026] By rotating the function box, users can make more effective use of limited space. For example, in field operations, when the operating table needs to be placed in a narrow or irregular space, users can adjust its position and angle by rotating the function box to adapt to different environmental requirements.

[0027] Furthermore, the baffle and the protective cover are made of glass.

[0028] Beneficial effects: The baffle and protective cover are both designed with glass material. The glass material has extremely high transparency, allowing users to clearly observe the crushing of the sample to be analyzed in the crushing chamber, which not only helps users accurately judge the crushing progress and results, but also improves the efficiency and accuracy of the overall geochemical analysis.

[0029] Furthermore, an adsorption layer and a magnetic attraction layer are respectively provided at one end of the two protective covers close to each other, and the adsorption layer corresponds to the magnetic attraction layer.

[0030] Beneficial effects: The corresponding arrangement of the adsorption layer and the magnetic layer enables the two protective covers to fit tightly together when they are closed, forming an effective sealing barrier, reducing the splashing of the sample to be analyzed out of the sample table during the crushing process, thereby improving the efficiency of crushing. Due to the attraction between the adsorption layer and the magnetic layer, the user only needs to gently bring the two protective covers close together, and the two will automatically adsorb and close tightly, which not only simplifies the operation process, but also improves work efficiency. At the same time, when the protective cover needs to be opened, the user only needs to apply a certain external force to easily separate it, without the need for additional unlocking or disassembly steps.

[0031] Furthermore, rubber pads are provided at the bottom of the support shell and the bottom of the support column.

[0032] Beneficial effects: The rubber pad has good anti-skid and shock-absorbing properties, which can significantly enhance the friction between the support shell and support column and the ground or other placement surface, thereby preventing the operating table from sliding or tipping over during use and improving the stability of the device. The rubber pad is soft and wear-resistant, and can form a buffer layer between the device and the placement surface, effectively preventing scratches, wear or dents caused by the weight or movement of the operating table, and increasing the service life of the device.

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: a portable geochemical analysis operating table, including a support shell 1, the top of the support shell 1 is integrally formed with a handle, so that the user can easily move the entire operating table from one place to another by holding the handle during the geochemical analysis process, without the need for laborious lifting or dragging; a functional box 9 is installed inside the support shell 1, and the inner top wall and the inner bottom wall of the support shell 1 are both provided with a rotation groove 3, the top and bottom of the functional box 9 are symmetrically provided with cylindrical sliders that slide with the rotation groove 3 respectively, and the cylindrical sliders are close to one end of the functional box 9 in the width direction, the top and bottom of the functional box 9 are symmetrically connected to the first connecting rod 11, and the other end of the first connecting rod 11 is respectively connected to the inner top wall and the inner bottom wall of the support shell 1; the functional box 9 is divided from left to right into a storage area for placing analysis tools and reagents and an operating area for geochemical analysis ( Figure 1 ). The storage area is embedded with a first drawer 4 and a second drawer 5, and the first drawer 4 is located below the second drawer 5. The design of multiple drawers can effectively utilize the space in the storage area, and different types of analysis tools, reagents or other necessities can be classified and stored. In the actual operation process, the user can quickly take out the required tools or reagents from the corresponding drawers as needed, reducing the preparation time, thereby improving the work efficiency of the entire analysis process.

[0046] An operation panel 6 hinged to a function box 9 and a baffle 7 located above the operation panel 6 are provided in the operation area. A crushing chamber corresponding to the baffle 7 is provided in the operation area. A crushing assembly for crushing and pre-treating the sample to be analyzed is installed in the crushing chamber.

[0047] The crushing assembly includes a motor screwed into the crushing chamber, the motor output shaft is coaxially keyed to a rotating disk 16, the right side of the rotating disk 16 is eccentrically fixedly connected to a push rod 15 and a coaxial screw connected to a second connecting rod 17 ( Figure 3 and Figure 4), the other end of the second connecting rod 17 is hinged with the third connecting rod 18, the other end of the third connecting rod 18 is hinged with the moving rod 19, the bottom of the moving rod 19 is screwed with a crushing head 20 and the moving rod 19 is slidably matched with the inner wall of the crushing chamber, the push rod 15 is slidably matched with the cam connecting rod 14, the inside of the crushing chamber is rotatably connected with the first rotating shaft 13 that is rotatably matched with the cam connecting rod 14, the cam part of the cam connecting rod 14 is bolted and fixedly connected with the fourth connecting rod 23, a swing groove 25 is opened on one side of the length direction of the sample table 21, the swing groove 25 is slidably matched with the fourth connecting rod 23, the sample table 21 is located in the movement track of the crushing head 20, and the bottom of the sample table 21 is hinged with a base 22 that is screwed and connected to the bottom wall of the crushing chamber. The top of the sample table 21 is symmetrically slidably matched with a protective cover 24 along the length direction, and the sliding matching method is the matching method of the slider slot.

[0048] Both cylindrical sliders are rotatably connected to the function box 9, and the length of the first connecting rod 11 is greater than the vertical distance between the two cylindrical sliders; the first connecting rod 11 is provided with grooves corresponding to the cylindrical sliders, thereby ensuring that the function box 9 can rotate 180°, so that the user can easily rotate the function box 9 to any desired angle as needed, so as to better perform sample analysis, reagent extraction or other operations. For example, in field operations, when the support shell 1 needs to be placed in a narrow or irregular space, the user can adjust its position and angle by rotating the function box 9 to adapt to different environmental requirements.

[0049] A stabilizing component is installed inside the function box 9, and the stabilizing component includes a stabilizing cavity opened inside the function box 9, a support column 8 is slidably fitted in the stabilizing cavity, and the bottom end of the support column 8 penetrates to the bottom end of the function box 9, the support column 8 and the function box 9 are slidably fitted, and a locking knob 12 is threadedly connected to the surface of the function box 9, and the support column 8 is located within the movement trajectory of the locking knob 12. When performing geochemical analysis on a slope, the user can adjust the height of the support column 8 to form a stable supporting relationship between the operating table and the ground, thereby reducing the possibility of the device shaking or tilting. At the same time, when the sample is crushed, strong vibrations may cause the operating table to shake or even fall over, and the stable triangular support structure formed by the support column 8 and the support shell 1 can ensure that the operating table remains stable and motionless, thereby protecting the sample and the operating table from damage.

[0050] At the same time, rubber pads are provided at the bottom of the support shell 1 and the bottom of the support column 8 to increase the wear resistance of the device. At the same time, the rubber pads have good anti-skid and shock-absorbing properties, which can significantly enhance the friction between the support shell 1 and the support column 8 and the ground or other placement surfaces, thereby preventing the operating table from sliding or tipping over during use. As for the shock-absorbing performance, when performing the pretreatment of sample crushing, the crushing head 20 impacts the sample table 21, which will cause a certain degree of vibration of the entire device, thereby improving the stability of the device through the shock-absorbing effect of the rubber pad, and reducing the possibility of some reagents placed on the operating panel 6 tipping over or falling off during subsequent operation and analysis.

[0051] The specific implementation process is as follows: first, the support shell 1 is placed on the ground, and the locking knob 12 is pulled to make the cylindrical sliders at the bottom and top of the function box 9 slide along the rotating groove 3. At the same time, the movement of the function box 9 is limited by the first connecting rod 11 respectively hinged to the support shell 1 and the function box 9, so that the function box 9 can complete the rotation (0-180°), so that the function box 9 is rotated to a suitable angle according to actual conditions, and then the locking knob 12 is turned to make the support column 8 extend to a suitable length to form a stable triangular support structure with the support shell 1, and then select a suitable tool from the first drawer 4 and the second drawer 5 to collect analytical samples (rocks, etc.). After the collection is completed, the baffle 7 is opened, and the sample to be analyzed is placed on the sample table 21 for crushing pretreatment; after the sample is placed, the two protective covers 24 are slid to close the two. Then the motor is started, and the motor output shaft drives the rotating disk 16 to rotate, and the rotating disk 16 will drive the push rod 15 eccentrically fixedly connected to it to revolve, so that the push rod 15 will slide in the through groove of the cam connecting rod 14, and push the cam connecting rod 14 to swing back and forth around the first rotating axis 13 within a certain angle range; during the swinging process of the cam connecting rod 14, the fourth connecting rod 23 fixedly connected to it will also swing around the first rotating axis 13, because one end of the fourth connecting rod 23 slides with the swinging groove 25 on one side of the sample stage 21, and the bottom of the sample stage 21 is hinged to the base 22, so that the sample stage 21 swings around it and The hinge of the base 22 swings, thereby constantly shaking the sample in the sample stage 21, reducing the possibility of it gathering in a dead corner; at the same time, when the rotating disk 16 rotates, it will also drive the second connecting rod 17 to rotate, and the rotation of the second connecting rod 17 will drive the third connecting rod 18 to move. Since the two ends of the third connecting rod 18 are respectively hinged to the second connecting rod 17 and the moving rod 19, and the moving rod 19 slides with the crushing chamber, the third connecting rod 18 moves in a plane, and the moving rod 19 moves back and forth in a vertical direction, so that the crushing head 20 at the bottom of the moving rod 19 impacts and crushes the sample in the sample stage 21. After the sample is crushed, a screen with a suitable mesh size is selected to further process the crushed sample, and then the processed sample is chemically analyzed.

[0052] Embodiment 2:

[0053] The difference from Example 1 is that Figure 1 As shown, a push-type buckle 2 is installed on the top of the support shell 1, and a card slot 10 corresponding to the buckle 2 is opened on the top of the function box 9. The push-type buckle 2 is combined with the card slot 10 on the top of the function box 9 to ensure the stability of the function box 9 in the support shell 1. Whether in transportation or in field operations, the function box 9 can be effectively prevented from moving due to vibration or external force, thereby protecting the internal analysis tools and reagents from damage. At the same time, the push-type buckle design allows the user to easily lock and unlock the function box 9. The user only needs to simply press the card operation buckle to quickly fix or release the function box 9 without complicated or tool assistance. It not only improves work efficiency, but also reduces the user's operating burden and improves convenience.

[0054] Embodiment 3:

[0055] The difference from Example 2 is that the baffle 7 and the protective cover 24 are both made of glass. For example, when crushing rock samples, the user can observe the crushing process of the sample by the crushing head 20 in real time through the transparent baffle 7 and the protective cover 24, including the crushing speed, crushing particle size, and whether there are large pieces of uncrushed sample remaining. This intuitive observation not only helps the user to accurately judge the crushing progress and results, but also can timely discover and adjust the crushing parameters to ensure that the sample particle diameter meets the analysis standard.

[0056] Embodiment 4:

[0057] The difference from Example 3 is that the two protective covers 24 are bonded with an adsorption layer and a magnetic layer respectively at one end close to each other, and the adsorption layer corresponds to the magnetic layer. During the crushing process of the sample to be analyzed, part of the sample will often splash out of the sample table 21 due to the impact of the crushing head 20, thereby affecting the crushing efficiency. When the two protective covers 24 are closed, the adsorption layer and the magnetic layer fit tightly to form an effective sealing barrier. At the same time, when the two protective covers 24 are closed, an opening is left above them so that the crushing head 20 can impact the sample in the sample table 21. At the same time, when the protective cover 24 needs to be opened and closed frequently to change the sample during the geological analysis process, the user only needs to apply a small force to easily separate or close the protective cover 24 without the need for additional unlocking or disassembly steps.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
