[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 4 A mobile coal quality rapid detection system 100 according to an embodiment of the present invention is described.

[0034] like Figure 1 As shown, the mobile coal quality rapid detection system 100 according to an embodiment of the present invention includes: a vehicle body 10, a sampling device 20, a sample preparation device 30, an automatic transfer device 40 and a detection mechanism 50.

[0035] Specifically, the vehicle body 10 has a mounting platform 11. The vehicle body 10 is a part of the vehicle, and thus the vehicle body 10 is movable. It should be noted that the vehicle can select a vehicle body 10 with good off-road performance and load-bearing capacity as the mounting platform 11, so that the stability and load-bearing capacity of the mounting platform 11 can be improved. In addition, optionally, a shock-absorbing device can be provided on the mounting platform 11, so that the vibration effect on the equipment during the driving of the vehicle can be reduced. At the same time, the mounting platform 11 can also be equipped with a power supply system to provide power support for the entire detection device.

[0036] The sampling device 20 is configured to extend into the coal layer to collect coal. It will be appreciated that when sampling and testing is required, the sampling device 20 is activated to extend into the coal layer to collect coal. In other words, when sampling and testing is required, the sampling device 20 is capable of penetrating deep into the coal layer to collect coal. This allows the obtained coal sample to be more representative, thereby improving the accuracy and reliability of the test results.

[0037] The sampling device 30 is fixed to the mounting platform 11. The sampling device 20 is adapted to convey coal to the sampling device 30. The sampling device 30 is configured to prepare the coal into a coal sample. It should be noted that the coal sampled by the sampling device 20 is generally oversized, and the samples required for coal testing have specific specifications. Therefore, prior to testing, the coal needs to be crushed by the sampling device 30 to the required sample specifications.

[0038] The automatic transfer device 40 and the detection mechanism 50 are both arranged on the installation platform 11. The automatic transfer device 40 is suitable for automatically transferring the coal sample to the detection mechanism 50. The detection mechanism 50 is configured to be suitable for detecting the coal sample.

[0039] It can be understood that when coal samples need to be tested, automatic sampling can be achieved through the automatic transfer device 40, and then automatic testing can be achieved through the testing mechanism 50. In this way, manual participation can be reduced, and errors caused by human factors can be reduced, thereby further improving the accuracy of the results. At the same time, the rate of coal quality testing can be further improved.

[0040] When it is necessary to inspect the quality of coal, the vehicle body 10 can be controlled to move to the coal sampling point first, and then the sampling device 20 can be controlled to extend into the coal accumulation layer to collect coal. The collected coal is transported to the sample preparation device 30 through the sampling device 20, and then the coal is processed by the sample preparation device 30. The processed coal sample is transferred to the detection mechanism 50 through the automatic transfer device 40, and then tested by the detection mechanism 50.

[0041] According to the mobile coal quality rapid detection system 100 of the present invention, by integrating the sampling device 20, the sample preparation device 30, the automatic transfer device 40 and the detection mechanism 50 on the installation platform 11 of the vehicle body 10, it is possible to realize the integrated operation of deep coal sampling and detection, thereby improving the efficiency of detection, thereby shortening the cycle of coal quality detection, and improving the work efficiency of coal quality inspection; at the same time, through the setting of the sampling device 20, the representativeness of coal sampling can also be improved, thereby further improving the accuracy and reliability of the detection results.

[0042] According to some embodiments of the present invention, Figure 2As shown, the sampling device 20 includes a sleeve 21 and a drill rod 22. The sleeve 21 has a first opening and a second opening 211. The first opening is adapted to connect to the inlet of the sampling device 30. The drill rod 22 has a spiral structure and is rotatably engaged within the sleeve 21. One end of the drill rod 22 is configured to extend through the second opening 211 to penetrate the coal layer and collect coal. Specifically, the drill rod 22 is primarily used to collect coal. When the drill rod 22 collects coal, it rotates and moves downward to drill the coal. The drill rod 22 and the sleeve 21 cooperate to form a spiral conveying channel. After the drill rod 22 completes sampling, the coal can be transported to the sampling device 30 through the spiral conveying channel.

[0043] Optionally, the drill rod 22 is made of a high-strength alloy material, so that the sampling device 20 can adapt to coal deposits of different hardnesses, thereby improving the adaptability of the detection device.

[0044] Optionally, the lifting and rotating movements of the drill rod 22 are achieved through a hydraulic drive system, wherein the hydraulic system can provide very high force or torque output in a relatively small volume. Thus, the lifting and rotating movements of the drill rod 22 are achieved through a hydraulic drive system, which can reduce the overall size of the sampling device 20 while ensuring the normal operation of the sampling device 20, thereby reducing the space occupied by the sampling device 20.

[0045] Optionally, the detection device further includes: a generator 80 , which is fixed on the mounting platform 11 and is used to provide power to the hydraulic drive system.

[0046] According to some embodiments of the present invention, the automatic transfer device 40 includes: a first robotic arm, the first robotic arm is disposed on the mounting platform 11, the sampling device 20 is adapted to be connected to the movable end 411 of the first robotic arm, and the first robotic arm is used to drive the sampling device 20 to move between a sampling position and a storage position, wherein, in the sampling position, one end of the sampling device 20 is adapted to extend into the coal accumulation layer to collect coal, and in the storage position, the sampling device 20 is stored on the mounting platform 11. It is understood that the sampling device 20 can be stored on the mounting platform 11 when not in use and placed in the sampling position when in use, so that the sampling device 20 can move with the mounting platform 11, thereby enabling sampling at different positions.

[0047] The robotic arm 41 is an automated device that can simulate the movements of a human arm and can perform precise movement and operation within a set range. Therefore, using the robotic arm 41 to move the sampling device 20 can save manpower while also automating the movement of the sampling device 20, thereby improving the sampling efficiency of the sampling device 20.

[0048] According to some embodiments of the present invention, Figure 1As shown, the mobile coal quality rapid testing system 100 further includes a gripping mechanism 60 adapted to grip a coal sample and place it at a testing location. The gripping mechanism 60 cooperates with the automatic transfer device 40 to position the coal sample at the testing location. Specifically, the gripping mechanism 60 automates the gripping of coal samples, reducing manual effort and improving overall processing efficiency.

[0049] According to some embodiments of the present invention, the automatic transfer device 40 further includes: a second robotic arm, the second robotic arm is arranged on the mounting platform 11, the gripping mechanism 60 includes: an electric gripper, the movable end 411 of the second robotic arm is suitable for being connected to the electric gripper, the electric gripper is suitable for gripping the coal sample, and the second robotic arm is used to drive the electric gripper to move between the sample preparation device 30 and the detection mechanism 50. Specifically, the electric gripper is an adaptive electric gripper, and its working principle is that it is driven by a motor, and the finger surface of the electric gripper performs linear reciprocating motion to realize opening or closing. Among them, through adaptive control, the electric gripper can intelligently and automatically adjust the clamping force and clamping method according to the characteristics and shapes of different workpieces. Therefore, the gripping mechanism 60 includes an electric gripper, which can improve the transfer efficiency and ensure the efficiency and stability of the gripping process.

[0050] In addition, the electric gripper is connected to the second robotic arm to achieve the grasping and transfer of coal samples. The robotic arm 41 is an automated device that can simulate the movements of human arms and can perform precise movement and operation within a set range. Therefore, the use of the robotic arm 41 in conjunction with the electric gripper can further improve the accuracy and automation of coal sample transfer.

[0051] According to some embodiments of the present invention, the first robotic arm and the second robotic arm are the same robotic arm 41. In this way, the overall components of the mobile coal quality rapid detection system 100 can be reduced, thereby reducing the production cost of the mobile coal quality rapid detection system 100.

[0052] The mobile coal quality rapid detection system 100 further includes an automatic assembly and disassembly device, which is configured to be suitable for installing the gripping mechanism 60 on the robotic arm 41 and removing the gripping mechanism 60 from the robotic arm 41, and suitable for installing the sampling device 20 on the robotic arm 41 and removing the sampling device 20 from the robotic arm 41. In this way, the robotic arm 41 can be automatically disassembled when switching between installing the gripping mechanism 60 and the sampling mechanism, thereby further improving the automation of sampling and detection of the mobile coal quality rapid detection system 100 and improving the detection rate of the mobile coal quality rapid detection system 100.

[0053] Furthermore, the robotic arm 41 adopts a multi-degree-of-freedom hydraulic drive design and has 360° horizontal rotation and pitch adjustment functions, so that the robotic arm 41 can flexibly adapt to different sampling scenarios.

[0054] According to some embodiments of the present invention, Figure 4 As shown, the detection mechanism 50 includes: a detection belt 51 and a detector 52. The detection belt 51 has a feed end 511 and a discharge end 512. The detector 52 includes: a near-infrared spectrum detection unit 521 and an X-ray fluorescence spectrum detection unit 522. The detector 52 is arranged between the feed end 511 and the discharge end 512, and the detector 52 is suitable for detecting coal samples. Specifically, the detection belt 51 is mainly used to drive the coal sample to rotate, so that the coal sample moves from the feed end 511 to the position of the detector 52. After the detection is completed, the tested coal sample is transferred to the discharge end 512 for output from the detection mechanism 50. The detector 52 is mainly used to test the coal sample to obtain various indicators of the coal sample.

[0055] Here, “the detector 52 includes: a near-infrared spectrum detection unit 521 and an X-ray fluorescence spectrum detection unit 522 ” can be understood as the detector 52 including both the near-infrared spectrum detection unit 521 and the X-ray fluorescence spectrum detection unit 522 .

[0056] Specifically, the near-infrared spectrum detection unit 521 analyzes the composition of the sample by measuring the absorption spectrum of the substance in the near-infrared region (approximately 780nm to 2500nm), and can quickly determine some physical and chemical properties of coal, such as moisture, ash, volatile matter and fixed carbon content.

[0057] X-ray fluorescence spectrometry detection unit 522 uses X-rays to illuminate the sample surface, exciting electrons within the sample atoms to higher energy levels or freeing them from the atoms. When these electrons return to their original energy levels, they emit fluorescent X-rays of a specific energy. X-ray fluorescence spectrometry detection unit 522 is primarily used to analyze the elemental composition of coal, particularly for the quantitative analysis of sulfur, chlorine, and other trace elements.

[0058] Optionally, the detection mechanism 50 also includes: a primary pressure roller 53 and a secondary pressure roller 54, wherein the primary pressure roller 53 and the secondary pressure roller 54 are arranged in sequence between the feed port and the detector 52 along the movement direction of the detection belt 51, wherein the primary roller pressure and the secondary roller pressure are mainly used to organize the coal samples entering the detection mechanism 50.

[0059] Reference Figure 4The coal sample detection process is as follows: first, the coal sample is transported to the feed end 511 through the grabbing mechanism 60, and the detection belt 51 drives the coal sample to rotate, and passes through the first-level pressing roller 53 and the second-level pressing roller 54 in sequence. At this time, the first-level pressing roller 53 and the second-level pressing roller 54 shape the coal sample so that the coal sample is formed into a coal flow of specified thickness and width, and then passes through the X-ray fluorescence spectrum detection unit 522 and the near-infrared spectrum detection unit 521 in sequence, and the coal sample is irradiated with X-ray and near-infrared light sources to detect the atomic spectra of Al, Si, S, K, Ca, Ti, Fe and other atoms in the coal, as well as the molecular spectra of C, H, O, N functional groups in the coal. Spectral data fusion and deep learning algorithms are used to establish a data model, and the collected spectral data are converted through the model to output coal calorific value, ash content, total sulfur, total moisture, volatile matter, ash melting point and other indicators in real time.

[0060] According to some embodiments of the present invention, the mobile coal quality rapid detection system 100 further includes: a sample storage box, which is suitable for being connected to the outlet end and / or the discharge end 512 of the sample preparation device 30, and is used to store coal samples and / or tested coal samples. Specifically, the sample storage box can be placed at the outlet end of the sample preparation device 30 to store the original coal sample so that it can be re-inspected or confirmed when needed later to ensure the accuracy and reliability of the test results; the sample storage box can also be placed at the discharge end 512 of the detection mechanism 50 to retain samples of the tested coal sample for subsequent review or storage; in addition, sample storage boxes can be provided at the discharge end 512 of the detection mechanism 50 and the outlet end of the sample preparation device 30.

[0061] Optionally, a sample processing device is further provided at the discharge end 512 of the detection mechanism 50 , and the sample processing device can perform processes such as crushing and shrinking the tested coal sample for subsequent review or storage.

[0062] According to some embodiments of the present invention, Figure 1As shown, the mobile coal quality rapid detection system 100 also includes a control device 70, which is fixed on the installation platform 11. The control device 70 is electrically connected to the sampling device 20, the sample preparation device 30, the automatic transfer device 40, and the detection mechanism 50 to control the sampling device 20, the sample preparation device 30, the automatic transfer device 40, and the detection mechanism 50. Specifically, the control device 70 can control the automatic sampling of the sampling device 20, for example, it can control the sampling depth and speed of the sampling device 20; the control device 70 can also control the automatic opening of the sample preparation device 30 to achieve automatic sample preparation of the coal sample; the control device 70 can also control the movement of the automatic transfer device 40 to achieve automatic transfer of the coal sample from the sample preparation device 30 to the detection mechanism 50; the control device 70 can also control the detection mechanism 50 to automatically detect the coal sample to obtain coal indicators. Therefore, the mobile coal quality rapid detection system 100 includes the control device 70, which can realize the automation of the sampling and detection process, thereby reducing the interference of human factors, and thus improving the accuracy of the detection results.

[0063] Optionally, the control device 70 includes: a data processing unit, a display unit, an information entry module and a wireless communication module, wherein the data processing unit analyzes and processes the detection data to quickly obtain the quality indicators of the coal; the display unit can display the coal quality indicators on the display; the information entry module can record the detection results and sampling information (such as sampling location, time, depth, etc.); the wireless communication module can transmit real-time information to the remote monitoring center so that management personnel can perform data analysis and decision-making.

[0064] Optionally, the control device 70 includes: a power distribution cabinet 71, a PLC control cabinet 72, a robotic arm control cabinet 73 and a detection mechanism control cabinet 74, wherein the robotic arm control cabinet 73 and the detection mechanism control cabinet 74 are communicatively connected to the PLC control cabinet 72, and the PLC control cabinet 72 includes a panel, and the operator can set parameters and monitor the equipment through the panel.

[0065] Optionally, the control device 70 is isolated from the sampling device 20, the sample preparation device 30, the automatic transfer device 40 and the detection mechanism 50 on the installation platform 11 by a dustproof plate. In this way, coal dust can be prevented from entering the control cabinet, thereby improving the safety and service life of the control device 70.

[0066] The detection method according to the second embodiment of the present invention is used in the mobile coal quality rapid detection system 100 according to the first embodiment of the present invention. The detection method includes:

[0067] Confirm that the mounting platform 11 is located at the coal sampling point; specifically, the mounting platform 11 is formed on the vehicle body 10, and thus, the vehicle's movement is controlled to move the mounting platform 11 to the coal sampling point. It should be noted that vehicles generally have a GPS positioning system, and thus, the location can be determined by the GPS positioning system, which can further improve the accuracy of positioning. Optionally, the mounting platform 11 also includes a stabilizing support mechanism. When the vehicle stops operating, the stabilizing support mechanism can be activated to ensure that the equipment remains stable during the sampling and testing process.

[0068] The robotic arm 41 is controlled to move the sampling device 20 to the sampling position, where it samples and transfers the coal to the sample preparation device 30. Specifically, the operator controls the robotic arm 41 via the control device 70 to move the sampling device 20 to the sampling position, sets the sampling depth and sampling frequency via the control device 70, and then activates the sampling device 20. At this point, the hydraulic drive system rotates the drill rod 22 and drills downward. When the preset depth is reached, drilling stops, and the spiral conveying channel transfers the collected coal sample to the sample preparation device 30.

[0069] The sampling device 30 crushes the coal to obtain a coal sample; specifically, the sampling device 30 crushes the coal obtained by the sampling device 20 into a size required for detection, and then stores the coal sample in a sample storage box.

[0070] Controlling the mechanical wall to drive the electric clamp to move, so as to clamp the coal sample and transport the coal sample to the feeding end 511 of the detection mechanism 50;

[0071] The testing mechanism 50 tests the coal samples.

[0072] Specifically, a vehicle with a mounting platform 11 is driven to a coal sampling location, and the stabilizing support mechanism of the mounting platform 11 is activated to stabilize the mounting platform 11. The operator then controls the robotic arm via the control device 70 to move the sampling device 20 to the sampling location, sets the sampling depth and sampling frequency via the control device 70, and then activates the sampling device 20 for sampling. Simultaneously, the sampling device 20 conveys the coal to the inlet of the sample preparation device 30 via a spiral conveyor. The sample preparation device 30 then starts and crushes the coal to obtain a coal sample. Simultaneously, the control device 70 controls the robotic arm 41 to retract the sampling device 20 and separate the robotic arm 41 from the sampling device 20. The robotic arm 41 is then secured to an electric gripper, gripping the coal sample and conveying it to the feed end 511 of the detection mechanism 50. The detection belt 51 conveys the coal sample to the detector 52, which performs real-time testing on the coal and outputs indicators such as coal calorific value, ash content, total sulfur, total moisture, volatile matter, and ash melting point.

[0073] Furthermore, after the detection mechanism 50 completes the coal sample detection, the detection mechanism 50 is closed, the stabilizing support mechanism is retracted, and then the vehicle is driven to the next sampling point to continue sampling and detection.

[0074] According to the detection method of an embodiment of the present invention, by integrating a sampling device 20, a sample preparation device 30, an automatic transfer device 40 and a detection mechanism 50 on the mounting platform 11 of the movable vehicle body 10, automatic sampling and detection of coal can be realized, thereby improving the accuracy and efficiency of detection.
