[0002] With the in-depth research and development and utilization of black soil resources, it is crucial to quickly and accurately grasp the chemical element composition and content of black soil. In the field of agricultural production, the fertility of black soil directly affects the growth and yield quality of crops, and its chemical element content is a key indicator for measuring fertility. At the same time, in the field of environmental science, understanding the distribution of chemical elements in black soil is of great significance for assessing the degree of soil pollution, ecosystem health, and sustainable land use.

[0003] However, the traditional method of detecting chemical elements in black soil has many drawbacks.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: Please see attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a black soil chemical element rapid detection and analysis device, including a base 1, which serves as a supporting structure of the entire device and provides a stable installation foundation for a detector 2, ensuring that the device will not be affected by factors such as shaking during the detection process. The top of the base 1 is fixedly connected with a detector 2, which is the core control and data processing part of the entire device. It integrates advanced electronic components and intelligent algorithms, is responsible for receiving signals from detection components, and performs rapid and accurate analysis and processing of these signals, and presents information such as the content of various chemical elements in the black soil in an intuitive manner. The outer wall of the base 1 is fixedly connected with a detection box 4, which is fixed to the outer wall of the base 1, and contains multiple key detection components and auxiliary components, forming a relatively independent and closed detection space, which is conducive to protecting the internal detection components from interference from external environmental factors, and ensuring the stability and reliability of the detection process. The top front side of the detection box 4 is rotatably connected with a cover plate 5 through a rotating plate 7, and the cover plate 5 is connected to the top front side of the detection box 4 through the rotating plate 7, so that the cover plate 5 can be flexibly opened and closed. During the detection process, when the cover 5 is closed, it can further seal the detection box 4 to prevent external impurities from entering and ensure the purity of the detection environment. When it is necessary to put in or take out the black soil sample, the detection box 4 can be opened by simply turning the cover 5. The operation is convenient. The inner wall of the detection box 4 is fixedly connected with a detection component, and the top of the detection box 4 is fixedly connected with a placement box 11. The placement box 11 is fixed on the top of the detection box 4 and is specially used for placing black soil samples and related components for preliminary processing of the samples before testing. A processing component is arranged inside the placement box 11, and the processing component is mainly used for crushing the black soil sample. A titration component is arranged on the outer wall of the placement box 11, a conveying component is arranged at the bottom of the detection box 4, and a transmission component is arranged at the bottom of the detection box 4; Please refer to the attached Figure 5 -Attached Figure 7The processing component includes a motor 18, which is fixedly connected to the bottom of the detection box 4. The motor 18 serves as a power source for the processing component and provides necessary power support for the processing of the black soil sample. The output end of the motor 18 is fixedly connected to a first rotating shaft 19 extending from the detection box 4 and the inner wall of the placement box 11. The first rotating shaft 19 is fixedly connected to the output end of the motor 18 and extends from the detection box 4 and the inner wall of the placement box 11 to transmit the power of the motor 18 to the rotating blade 20 and the first eccentric wheel 21 in the placement box 11, so as to realize the processing of the black soil. The sample processing function is that a rotating blade 20 and a first eccentric wheel 21 are fixedly connected to the outer wall of the first rotating shaft 19. The rotating blade 20 rotates at a high speed with the rotation of the first rotating shaft 19 to cut and crush the black soil sample placed in the placement box 11. The first eccentric wheel 21 rotates eccentrically driven by the first rotating shaft 19 to generate periodic vibrations to provide a power source for the oscillation component. An oscillation component is provided on the outer wall of the first eccentric wheel 21 to strike the placement box 11 to generate vibrations, thereby improving the cutting and crushing efficiency.

[0022] Please refer to the attached Figure 5 and attached Figure 6 The oscillation component includes a shell 22, which is mounted on the outer wall of the first eccentric wheel 21. The shell 22 is mounted on the outer wall of the first eccentric wheel 21, and serves as the outer shell of the oscillation component to protect the internal components and guide the movement direction of the slide bar 23. The shell 22 is slidably connected to the slide bar 23, and the slide bar 23 can reciprocate along a specific direction inside the shell 22. When the first eccentric wheel 21 rotates eccentrically, it will periodically push the slide bar 23 to slide in the shell 22, and convert the rotational motion of the eccentric wheel into a linear reciprocating motion of the slide bar 23. This precise motion conversion mechanism ensures that the oscillation component can work stably and efficiently. A hammer block 24 is fixedly connected to one side of the slide bar 23. The hammer block 24 is fixed to one side of the slide bar 23. As the slide bar 23 reciprocates, the hammer block 24 While the inner wall of the placement box 11 is being hammered, the other side of the slide bar 23 is fixedly connected to a limiting block 25, which is fixed to the other side of the slide bar 23. Its main function is to limit the sliding range of the slide bar 23 to prevent the slide bar 23 from separating from the shell 22 during movement, thereby ensuring the normal operation of the oscillation component. The side of the limiting block 25 away from the inner wall of the shell 22 is fixedly connected to a first spring 26. When the slide bar 23 slides to one side under the action of the first eccentric wheel 21, the first spring 26 is compressed to store elastic potential energy; when the force of the eccentric wheel disappears, the first spring 26 releases the elastic potential energy and pushes the slide bar 23 to slide in the opposite direction, so that the slide bar 23 can reciprocate quickly and stably, thereby ensuring that the hammering action of the hammering block 24 on the inner wall of the placement box 11 is continuous and uniform.

[0023] Please refer to the attached Figure 1 -Attached Figure 3The detection assembly includes a first support rod 8, which is fixedly connected to the inside of the detection box 4. The first support rod 8 plays an important role in supporting and fixing other components in the detection assembly. The outer wall of the first support rod 8 is fixedly connected to a first mounting plate 9, which is fixed to the outer wall of the first support rod 8, providing a flat and stable installation platform for the X-ray fluorescence spectrometer 10. The bottom of the first mounting plate 9 away from the first support rod 8 is fixedly connected to the X-ray fluorescence spectrometer 10. The X-ray fluorescence spectrometer 10 is one of the key instruments for detecting chemical elements in black soil. Its working principle is to use X-rays to irradiate black soil samples so that the elements in the samples are excited and emit secondary X-rays with specific energy. By detecting the energy and intensity of these fluorescent X-rays, the types and contents of various elements in the black soil can be determined.

[0024] Please see attached Figure 3 The titration assembly includes a second support rod 14, which is fixedly connected to the detection box 4. The second support rod 14 is fixed to the detection box 4 to provide a support and fixing basis for other components in the titration assembly. A second mounting plate 15 is fixedly connected to the top of the second support rod 14. The second mounting plate 15 is fixed to the top of the second support rod 14 to provide a suitable installation position and angle for the dripper 16. The bottom of the second mounting plate 15 away from the second support rod 14 is fixedly connected to the dripper 16. The dripper 16 is a key component of the titration assembly and is responsible for accurately dripping the reagent into the black soil sample.

[0025] Please see attached Figure 8The conveying assembly includes a cylinder 32 and a storage box 41, which are both fixedly connected to the inside of the test box 4. The cylinder 32 and the storage box 41 are both fixed to the inside of the test box 4. They together constitute the main structure of the conveying assembly, which is used to store and convey liquid substances such as reagents. A connecting rod 33 is slidably connected to the inside of the cylinder 32. The connecting rod 33 can slide back and forth inside the cylinder 32. The sliding connection between it and the cylinder 32 has good sealing and low friction, ensuring that no leakage occurs during the reagent delivery process, and can flexibly respond to external driving forces. The top of the connecting rod 33 is fixedly connected with an extrusion plate 34, which is fixed to the top of the connecting rod 33 and has a large area. It can effectively evenly distribute the force transmitted by the transmission assembly on the connecting rod 33, so that the connecting rod 33 can slide up and down stably in the cylinder 32. When the second eccentric wheel 31 rotates and pushes the extrusion plate 34, the extrusion plate 34 transmits force to the connecting rod 33, thereby driving the piston 35 to move. A piston 35 is fixedly connected to the bottom of the connecting rod 33. The piston 35 is fixed to the bottom of the connecting rod 33 and closely matches the inner wall of the cylinder 32 to form a sealed space for extracting and discharging reagents. When the connecting rod 33 moves up and down in the cylinder 32, the piston 35 moves accordingly, changing the pressure in the cylinder 32, thereby realizing the suction and discharge of the reagent. A second spring 36 is fixedly connected to the bottom of the squeezing plate 34. The second spring 36 is connected to the bottom of the squeezing plate 34 to play a role of buffering and resetting. When the second eccentric wheel 31 pushes the squeezing plate 34 to move downward, the second spring 36 is compressed to store elastic potential energy; when the force of the eccentric wheel disappears, the second spring 36 releases elastic potential energy and pushes the squeezing plate 34 to reset upward. An electromagnetic one-way valve 37 and a check valve 39 are fixedly connected to the bottom of the cylinder 32, respectively. The electromagnetic one-way valve 37 is used to control the process of the reagent entering the cylinder 32 from the storage box 41. When the electromagnetic one-way valve 37 is opened, the reagent is sucked from the storage box 41 into the cylinder 32 under the negative pressure generated by the movement of the piston 35 in the cylinder 32; when the electromagnetic one-way valve 37 is closed, the reagent is prevented from flowing back to the storage box 41, thereby ensuring the unidirectionality and accuracy of the reagent delivery. When a titration operation is required, the electromagnetic one-way valve 37 can accurately control the amount of reagent inhaled, provide accurate reagent reserves for subsequent titrations, and improve the accuracy and reliability of the detection process. The check valve 39 is used to prevent the reagent from flowing back from the cylinder 32 to the dripper 16 or other components, ensuring that the reagent can only flow from the cylinder 32 to the dripper 16 in a predetermined direction, and then drip into the black soil sample. This one-way flow control mechanism ensures the stability and accuracy of the titration process and avoids experimental errors caused by reagent backflow.

[0026] Please refer to the attached Figure 7The transmission assembly includes a fixed plate 29 and an active bevel gear 27. The active bevel gear 27 is fixedly connected to the outer wall of the first rotating shaft 19. The active bevel gear 27 is fixed to the outer wall of the first rotating shaft 19 and rotates with the rotation of the first rotating shaft 19 to transmit the power of the motor 18 to the driven bevel gear 28. The fixed plate 29 is fixedly connected to the bottom of the detection box 4. The fixed plate 29 is fixed to the bottom of the detection box 4 to provide a support and fixing basis for other components in the transmission assembly. The middle part of the fixed plate 29 is rotatably connected to the second rotating shaft 30. The second rotating shaft 30 is used to realize power transmission. A second eccentric wheel 31 is fixedly connected to one side of the second rotating shaft 30. The second eccentric wheel 31 is fixed to one side of the second rotating shaft 30 and performs eccentric movement with the rotation of the second rotating shaft 30. Its eccentric part contacts the top of the squeeze plate 34, and provides power for reagent delivery by periodically pushing the squeeze plate 34 up and down. The other side of the second rotating shaft 30 is fixedly connected with a driven bevel gear 28, which is fixed on the other side of the second rotating shaft 30, meshing with the active bevel gear 27, receiving the power transmitted by the active bevel gear 27, and driving the second rotating shaft 30 and the second eccentric wheel 31 to rotate. The active bevel gear 27 and the driven bevel gear 28 are meshed, and the meshing transmission between the active bevel gear 27 and the driven bevel gear 28 is the key link of the transmission assembly. It can change the transmission direction and speed of power, and reasonably adjust the speed and torque output by the motor 18 according to the needs of the equipment to drive the second eccentric wheel 31 to work.

[0027] Please refer to the attached Figure 1 and attached Figure 2 The detector 2 is provided with a display screen 3 on its surface. The display screen 3 is provided on the surface of the detector 2 and is an important interface for human-computer interaction. It can intuitively display the results of the black soil chemical element detection, including the content, concentration and other data of various elements, as well as the operation status information of the equipment, such as the detection progress and whether there is a fault. A connection lock 6 is provided between the detection box 4 and the cover plate 5. The connection lock 6 is provided between the detection box 4 and the cover plate 5 to ensure the sealing and stability of the cover plate 5 in the closed state.

[0028] Please refer to the attached Figure 4, the top of the placement box 11 is threadedly connected with a protective cover 12 through a threaded groove 17, and the protective cover 12 is threadedly connected to the top of the placement box 11 through the threaded groove 17, and has good sealing and stability. After the black soil sample is placed in the placement box 11, tightening the protective cover 12 can effectively prevent the sample from splashing during the processing process, protect the safety of the operator and the cleanliness of the laboratory environment. At the same time, the protective cover 12 can also reduce the contact between the sample and the outside air, avoid certain components in the sample from changing due to factors such as oxidation or volatilization, and ensure that the original properties and components of the sample are stable, thereby improving the accuracy and reliability of the test results. The top edge of the protective cover 12 is fixedly connected with a leakage net 13. When the reagent is dripped into the placement box 11 through the dripper 16 for chemical analysis, the leakage net 13 can prevent the impurities that may remain in the reagent bottle from entering the sample, avoiding the interference of these impurities with the chemical reaction, thereby ensuring the accuracy and reliability of the test results.

[0029] Please refer to the attached Figure 3 and attached Figure 8 A suction tube 38 is fixedly connected between the electromagnetic one-way valve 37 and the storage box 41. The suction tube 38 is connected between the electromagnetic one-way valve 37 and the storage box 41, and serves as a channel for the reagent to enter the cylinder 32 from the storage box 41. A discharge pipe 40 is fixedly connected between the check valve 39 and the dripper 16. The discharge pipe 40 is connected between the check valve 39 and the dripper 16, and is used to transport the reagent in the cylinder 32 to the dripper 16, and finally drip it into the black soil sample.

[0030] Please refer to the attached Figure 5 and attached Figure 7 The eccentric part of the second eccentric wheel 31 fits with the top of the extrusion plate 34. The fitting design between the eccentric part of the second eccentric wheel 31 and the top of the extrusion plate 34 ensures that the rotation of the eccentric wheel can effectively push the extrusion plate 34 to move up and down, thereby providing stable power for reagent delivery. The beating block 24 fits with the inner wall of the placement box 11. The fitting between the beating block 24 and the inner wall of the placement box 11 ensures that when the first eccentric wheel 21 rotates, the beating block 24 can powerfully beat the inner wall of the placement box 11, so that the black soil sample in the placement box 11 is fully shaken and mixed.

[0031] Working principle: First, place the collected black soil sample in the placement box 11, and tighten the protective cover 12 connected to the placement box 11 through the threaded groove 17. At this time, the mesh 13 on the top edge of the protective cover 12 can prevent impurities from entering the sample, thereby ensuring the purity of the sample.

[0032] Start the motor 18, the motor 18 drives the first rotating shaft 19 to rotate, and the rotating blade 20 fixed on the outer wall of the first rotating shaft 19 rotates at high speed, cutting and crushing the black soil sample, making its particles smaller and more uniform, which is convenient for subsequent detection and analysis. At the same time, the first eccentric wheel 21 on the first rotating shaft 19 rotates eccentrically to drive the oscillation component to work. The rotation of the first eccentric wheel 21 causes the slide bar 23 in the housing 22 installed on its outer wall to slide back and forth, and the beating block 24 on one side of the slide bar 23 beats the inner wall of the placement box 11. The limit block 25 on the other side of the slide bar 23 ensures that the slide bar 23 stably reciprocates under the buffering and resetting action of the first spring 26, so that the sample in the placement box 11 is fully shaken and mixed, further improving the uniformity of the sample.

[0033] During the detection process, when the sample needs to be chemically analyzed and the titration method is used, the electromagnetic one-way valve 37 is opened, and under the negative pressure generated by the movement of the piston 35 in the cylinder 32, the reagent is sucked from the storage box 41 into the cylinder 32 through the suction tube 38. When the motor 18 rotates, the active bevel gear 27 on the first rotating shaft 19 drives the driven bevel gear 28 meshing therewith to rotate, thereby rotating the second rotating shaft 30, and the second eccentric wheel 31 on one side of the second rotating shaft 30 rotates accordingly. The eccentric part of the second eccentric wheel 31 periodically pushes the squeezing plate 34 to move up and down, and the second spring 36 at the bottom of the squeezing plate 34 plays a buffering and resetting role to ensure the stable movement of the squeezing plate 34. The movement of the extrusion plate 34 drives the connecting rod 33 and the piston 35 at the bottom to move up and down in the cylinder 32, and the reagent in the cylinder 32 is transported to the dripper 16 through the check valve 39 and the discharge pipe 40. The dripper 16 accurately drips the reagent into the black soil sample in the placement box 11 to carry out a chemical reaction, so as to carry out a more in-depth analysis and detection of the chemical elements in the sample later.

[0034] A detection assembly is fixed to the inner wall of the detection box 4 below the placement box 11, wherein the first support rod 8 supports the first mounting plate 9, and the X-ray fluorescence spectrometer 10 on the first mounting plate 9 can emit X-rays to the processed black soil sample, so that the elements in the sample are excited to produce fluorescent X-rays with specific energy. By detecting the energy and intensity of these fluorescent X-rays, the types and contents of various elements in the black soil can be determined. The test results are intuitively displayed through the display screen 3 on the surface of the detector 2 for the operator to view and record, thereby completing the rapid detection and analysis process of the chemical elements in the black soil. During the whole process, the connecting lock 6 between the detection box 4 and the cover plate 5 ensures the closedness of the detection environment to prevent external factors from interfering with the test results.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
