Technical Field

[0001] The present application belongs to the technical field of mineral detection, and specifically relates to a mineral detection vehicle. Background Art

[0002] In recent years, the problem of air pollution has become increasingly serious, and the irrational use of minerals and the use of inferior minerals are one of the reasons for the increasingly serious air pollution. Therefore, sampling and testing of minerals before they are put into use is a crucial process.

[0003] In the related technology, minerals are usually sampled on the move using a sampling vehicle. The sampling vehicle can be flexibly moved to different places and locations to sample minerals in different locations. The sampled mineral samples will be sent to the laboratory for testing and analysis, that is, the mineral samples will be transported to the laboratory for reduction, sample preparation and testing. The whole process generally takes a relatively long time, resulting in a long sampling and testing time, and there are serious lags. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide a mineral detection vehicle, which can integrate sampling, sample preparation and testing to address the shortcomings of traditional vehicle-mounted sampling and preparation, and can simultaneously output multiple indicators such as calorific value, total water, sulfur content, ash content, etc.

[0005] The embodiment of the present application provides a mineral detection vehicle, including a vehicle body, a sampling arm, a sample preparation device, a conveying device and a detection device, wherein the sampling arm can be movably arranged on the vehicle body, the sample preparation device, the conveying device and the detection device are all arranged on the vehicle body, the sampling arm is used to collect minerals and transport the minerals to the sample preparation device, the sample preparation device is used to prepare mineral samples according to the minerals collected by the sampling arm, and the outlet end of the sample preparation device is opposite to the feed end of the conveying device, so that the conveying device conveys the mineral samples, In the conveying direction of the conveying device, the detection device is located downstream of the sample preparation device, so that the detection device detects the mineral sample conveyed by the conveying device.

[0006] In an embodiment of the present application, a sampling arm, a sample preparation device and a detection device are simultaneously provided on the body of the mineral detection vehicle. Sampling is performed using the sampling arm, and a mineral sample that meets the requirements is prepared using the sample preparation device to realize the sampling and sample preparation process, and then the mineral sample is detected by the detection device.

[0007] With this arrangement, the sampling, sample preparation and testing processes are carried out sequentially on the vehicle body, and there is no need to perform testing outside the vehicle body, thus avoiding long intervals between sampling and testing, shortening the entire sampling and testing time, and avoiding the problem of long sampling and testing times due to time lags.

[0008] Optionally, the detection device includes a near-infrared light detection module and an X-ray fluorescence detection module that are arranged at intervals, the near-infrared light detection module uses near-infrared light to detect molecular information in the mineral sample and generate a molecular spectrum, and the X-ray fluorescence detection module uses X-ray fluorescence to detect atomic information in the mineral sample and generate an atomic spectrum, and multiple components in the mineral sample are detected based on the molecular spectrum and the atomic spectrum.

[0009] In this way, the detection device is simultaneously provided with a near-infrared light detection module and an X-ray fluorescence detection module. The near-infrared light detection module uses the principle of near-infrared light to obtain a near-infrared spectrum through near-infrared light diffusely reflected from the surface of the mineral sample, and then detects molecular spectra containing C, H, O, N functional groups and the like in the mineral, while the X-ray device uses X-rays to accurately detect atomic spectra such as Si, Al, Ca, Fe, K, S and the like in the mineral. The combination of the X-ray spectrum and the near-infrared spectrum can obtain richer characteristic spectra and more accurately detect parameters such as calorific value, sulfur content, total water content, and ash content.

[0010] Optionally, the sample preparation device includes a reducer, which is provided with a reduction inlet and a mineral sample outlet, the mineral collected by the sampling arm can enter the reduction inlet, and the mineral sample after reduction by the reducer flows out from the mineral sample outlet.

[0011] With such an arrangement, the minerals are reduced by using the reducer to screen out representative minerals as mineral samples, and the detection device is used to detect the mineral samples, which is beneficial to improving the accuracy of mineral detection.

[0012] Optionally, the sample preparation device further comprises a crusher, the sampling arm can deliver the collected mineral sample into the crusher, and the outlet end of the crusher is connected to the reduction inlet.

[0013] With such arrangement, before the mineral enters the reducer, it first undergoes a crushing process in the crusher, so that the particle size of the mineral that finally enters the detection device meets the requirements.

[0014] Optionally, the sample preparation device further comprises a first collecting device, which is used to collect the minerals divided by the divider, and the divider is further provided with a mineral outlet, which is connected to the inlet end of the first collecting device.

[0015] With such arrangement, the first collecting device is utilized to separately seal the minerals flowing out of the reducer, so that subsequent separate testing of this part of the minerals is convenient.

[0016] Optionally, the size of the mineral sample after being reduced by the reducer is less than 6 mm.

[0017] With such arrangement, the size of the mineral sample falling into the conveying device is smaller, thereby avoiding the irregular mineral flow caused by the excessive volume of the mineral sample, thereby avoiding affecting the detection accuracy of the detection device.

[0018] Optionally, the mineral detection vehicle also includes a hopper, the inlet end of the hopper is connected to the outlet end of the sample preparation device, the outlet end of the hopper is opposite to the feed end of the conveying device, the hopper is provided with a detection element, the detection element is used to detect the weight of the mineral sample in the hopper, the outlet end of the hopper is provided with a control valve, the control valve is communicatively connected with the detection element, when the detection element detects that the weight of the mineral sample is within a preset range, the control valve is in an open state, and the mineral sample in the hopper enters the conveying device.

[0019] In this way, by setting the hopper, the detection element and the switch valve, the weight of the mineral sample falling into the conveying device is within the preset range, ensuring that the mineral flow is smoothly formed, which is conducive to improving the accuracy of the detection result. In addition, the detection element is connected to the control valve in communication, so that when the weight of the mineral sample is within the preset range, the control valve can be opened in time and quickly, ensuring that the mineral sample enters the conveying device in time, saving reaction time and improving detection efficiency.

[0020] Optionally, the detection element includes a relative photoelectric transmitter and a photoelectric receiver, the photoelectric transmitter is used to emit laser, and the photoelectric receiver is used to receive the laser emitted by the photoelectric transmitter, and when the laser emitted by the photoelectric transmitter is blocked by the mineral sample, the control valve is in an open state; or, the detection element is a weight sensor, and when the weight sensor detects that the weight of the mineral sample reaches a preset weight value, the control valve is in an open state.

[0021] With such a configuration, the detection element adopts a through-beam photoelectric sensor, which has a long service life and a short response time, is conducive to the timely opening of the control valve, and does not require direct contact with the mineral sample; the weight sensor has high accuracy and strong stability, and directly feedbacks whether the quality of the mineral sample reaches the preset value by detecting the weight of the mineral sample, which is convenient for directly judging whether the quality of the mineral sample meets the requirements.

[0022] Optionally, the preset range is 10 Kg-15 Kg.

[0023] With such arrangement, the weight of the mineral sample falling into the conveying device is within the range of 10 Kg-15 Kg, so the weight of the mineral sample is within a relatively suitable range, avoiding the mineral sample falling into the conveying device from being too heavy or too light.

[0024] Optionally, the mineral detection vehicle further comprises a vibrator, and the vibrator is arranged on a side wall of the hopper.

[0027] With such an arrangement, the rectifying device rectify the mineral sample, which is beneficial to improving the density, stability and flatness of the mineral sample. Moreover, the mineral sample falling into the conveying device is first rectified by the rectifying device and then passes through the detection process of the detection device. Therefore, the detection device detects the mineral sample in a regular state, which is more conducive to improving the detection accuracy.

[0028] Optionally, the mineral detection vehicle further comprises a control device, which is disposed on the vehicle body and is communicatively connected with the sampling arm, the sample preparation device, the conveying device and the detection device respectively.

[0029] With such an arrangement, the control device is used to control the sampling arm, sample preparation device, conveying device and detection device respectively, and the mineral detection vehicle automatically realizes each process of sampling, sample preparation, conveying and detection, with a high degree of automation, without the need for human participation, thus saving manpower.

[0030] Optionally, the mineral detection vehicle further includes a battery module, which is disposed on the vehicle body and is electrically connected to the sampling arm, the sample preparation device, the conveying device and the detection device, respectively, so as to detect the mineral sample when the vehicle body is not working.

[0031] With such an arrangement, a battery module is added separately, and the battery module supplies power to each electrical component separately, so that detection can be performed in a vibration-free state, which is beneficial to improving detection accuracy.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0038] The mineral detection vehicle provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] Please refer to Figure 1-Figure 6 The mineral detection vehicle includes a vehicle body 100, a sampling arm 200, a sample preparation device 300, a conveying device 500 and a detection device 600. The vehicle body 100 serves as the installation base for the sampling arm 200, the sample preparation device 300, the conveying device 500 and the detection device 600, and is used to carry various components. Moreover, the vehicle body 100 is movably arranged to drive various components to move to different places to sample and detect minerals in different places; the sampling arm 200 is used to collect minerals and transport the minerals to the sample preparation device 300, the sample preparation device 300 is used to prepare mineral samples S according to the minerals collected by the sampling arm 200, the conveying device 500 is used to transport the mineral samples S, and the detection device 600 is used to detect the mineral samples S.

[0040] The mineral may be coal, and the mineral sample S is a coal sample. Of course, the mineral may also be other minerals besides coal. The embodiment of the present application does not limit the specific category of the mineral.

[0041] The sampling arm 200 is movably disposed on the vehicle body 100. Optionally, the vehicle body 100 is provided with a support 110. One end of the support 110 can be connected to the vehicle body 100 by welding, bonding, etc. The sampling arm 200 is movably disposed on the other end of the support 110. Further, optionally, the sampling arm 200 is rotatably disposed on the support 110 via a rotating shaft. The sampling arm 200 can be an electric sampling arm, which is equivalent to an automatic manipulator in the prior art.

[0042] The conveying device 500 is a belt conveyor.

[0043] The sample preparation device 300, the conveying device 500 and the detection device 600 are all arranged on the vehicle body 100, and the outlet end of the sample preparation device 300 is opposite to the feed end of the conveying device 500, so that the mineral sample S prepared by the sample preparation device 300 can flow out from its outlet end and enter the conveying device 500, so that the conveying device 500 conveys the mineral sample S. Moreover, in the conveying direction of the conveying device 500, the detection device 600 is located upstream of the sample preparation device 300, so that the detection device 600 detects the mineral sample S conveyed by the conveying device 500.

[0044] Optionally, the sampling arm 200, the sample preparation device 300 and the conveying device 500 can be arranged at intervals along the conveying direction of the conveying device 500. Along the conveying direction of the conveying device 500, the sampling arm 200 is located upstream of the conveying device 500, the sampling arm 200 is also located upstream of the sample preparation device 300, and the detection device 600 is located in the area between the feeding end and the discharging end of the conveying device 500. Of course, the sampling arm 200, the sample preparation device 300 and the conveying device 500 can be arranged at intervals along other directions, as long as the processes of sampling, sample preparation, conveying and detection can be realized in sequence.

[0045] In an embodiment of the present application, a sampling arm 200, a sample preparation device 300 and a detection device 600 are simultaneously provided on the body 100 of the mineral detection vehicle. The sampling arm 200 is used for sampling, and the sample preparation device 300 is used to prepare a mineral sample S that meets the requirements, thereby realizing the sampling and sample preparation process. Then, the mineral sample S is detected by the detection device 600.

[0046] With such an arrangement, the sampling, sample preparation and testing processes are carried out sequentially on the vehicle body 100, without the need to perform testing outside the vehicle body 100, thereby avoiding a long interval between sampling and testing, shortening the entire sampling and testing time, and avoiding the problem of long sampling and testing time caused by time lag.

[0047] In an optional embodiment, the detection device 600 includes a near-infrared light detection module 610 and an X-ray fluorescence detection module 620 that are spaced apart. The near-infrared light detection module 610 uses near-infrared light to detect molecular information in the mineral sample S and generate a molecular spectrum. The X-ray fluorescence detection module 620 uses X-ray fluorescence to detect atomic information in the mineral sample S and generate an atomic spectrum. Further, multiple components in the mineral sample S can be detected based on the molecular spectrum and the atomic spectrum. The multiple components here include carbon, hydrogen, nitrogen, sulfur, moisture, ash, etc., and parameter information such as calorific value can also be obtained. Optionally, based on the atomic spectrum and the molecular spectrum, a neural network model technology is used to detect multiple components, specifically by combining near-infrared spectroscopy technology with X-ray fluorescence spectroscopy technology, and using an artificial intelligence algorithm to effectively fuse the molecular spectrum and the atomic spectrum, thereby achieving rapid, accurate, and non-destructive mineral component analysis.

[0048] Optionally, the near-infrared light detection module 610 and the X-ray fluorescence detection module 620 may be arranged at intervals along the conveying direction of the conveying device 500 .

[0049] Specifically, the X-ray fluorescence detection module 620 can use X-rays to detect atomic information such as Si, Al, Ca, Fe, K, and S in the mineral sample S. X-rays are particle streams generated by the transition of electrons in atoms between two energy levels with a large energy difference. They are electromagnetic radiation with a wavelength between ultraviolet rays and gamma rays. The wavelength of X-rays is relatively short, ranging from 0.01nm to 100nm, and the frequency range is 30PHz to 30EHz. The near-infrared light detection module 610 is provided with a transmitting end and a receiving end. The transmitting end is used to emit near-infrared light to the mineral sample S. Near-infrared light is an electromagnetic wave between visible light and mid-infrared light, with a wavelength in the range of 780nm to 2526nm. The receiving end is used to collect near-infrared light after diffuse reflection from the mineral sample S. The near-infrared light detection module 610 mainly detects molecular information such as C, H, O, and N in the mineral sample S.

[0050] In this embodiment, the detection device 600 is provided with an X-ray fluorescence detection module 620 and a near-infrared light detection module 610 at the same time. The X-ray spectrum and the near-infrared spectrum are coordinated to obtain a richer characteristic spectrum and more accurately detect parameters such as calorific value, total sulfur, total water, and ash content.

[0051] Of course, in other embodiments, the detection device 600 may also be provided with other detectors besides the near-infrared light detection module 610 and the X-ray fluorescence detection module 620 to detect the calorific value, total sulfur, total water, ash content and other parameters of the mineral sample S.

[0052] In this embodiment, the X-ray fluorescence detection module 620 includes an X-ray generator and an X-ray detector arranged in sequence. The X-ray generator is used to emit X-rays to the mineral sample S, and the X-ray detector is used to detect the fluorescence information generated by the mineral sample S after being excited by the X-rays, and the element information in the mineral sample S is fed back through the fluorescence information.

[0053] With this setting, the fluorescence line intensity and backscattering intensity of Si and Ca in the X-ray spectrum are well correlated with the ash content, respectively. Therefore, through the X-ray spectrum, elements such as Na, K, Si, Al, Ca, Mg, Zn, Fe, and Mn can be accurately detected, and the element information in the mineral sample S can be accurately fed back.

[0054] In the scheme of this application, reference is made to Figure 1 and Figure 2As shown, the sample preparation device 300 includes a reducer 320, and the reducer 320 is provided with a reduction inlet 321 and a mineral sample outlet 322. The mineral collected by the sampling arm 200 can enter the reduction inlet 321, and the mineral sample S after reduction by the reducer 320 flows out from the mineral sample outlet 322, and the mineral sample outlet 322 is connected to the feed end of the conveying device 500. In this way, the mineral sample S after reduction by the reducer 320 enters the feed end of the conveying device 500 and is conveyed by the conveying device 500.

[0055] Optionally, the reducer 320 can be located above the feed end of the conveying device 500, and the mineral sample S flowing out of the mineral sample outlet 322 falls directly into the conveying device 500, or the mineral sample outlet 322 is connected to the feed end of the conveying device 500 through a first connecting piece, and the mineral sample S flowing out of the mineral sample outlet 322 flows into the conveying device 500 through the first connecting piece.

[0056] Specifically, the reducer 320 is a device used to divide a large amount of minerals into smaller samples in a certain proportion for further analysis or processing. The reducer 320 can adopt a rotary, hammer, tube, turntable or other working modes. The embodiment of the present application does not limit the specific type of the reducer 320.

[0057] In this embodiment, the minerals are reduced by the reducer 320 to screen out representative minerals as the mineral samples S, and the detection device 600 detects the mineral samples S, which is beneficial to the accuracy of mineral detection.

[0058] Of course, in other embodiments, the sample preparation device 300 may use other components besides the divider 320 to prepare the mineral sample S.

[0059] In an alternative embodiment, reference Figure 1 As shown, the sample preparation device 300 also includes a crusher 310, and the sampling arm 200 can deliver the collected mineral sample S into the crusher 310, and the outlet end of the crusher 310 is connected with the reduction inlet 321. Optionally, the crusher 310 can be located above the reducer 320, and the minerals crushed by the crusher 310 directly fall into the reduction inlet 321 of the reducer 320; or, the crusher 310 can be located at other positions of the reducer 320, and the outlet end of the crusher 310 is connected with the reduction inlet 321 through a second connecting piece, and the minerals crushed by the crusher 310 flow into the reducer 320 through the second connecting piece.

[0060] According to this embodiment, before the mineral enters the reducer 320, it first undergoes a crushing process in the crusher 310, so that the particle size of the mineral that finally enters the detection device 600 meets the requirements.

[0061] In a further embodiment, reference Figure 1and Figure 2 As shown, the sample preparation device 300 also includes a first material collection device 710, which is used to collect the minerals divided by the divider 320. The first material collection device 710 can be a material collection box, a material collection hopper, a material collection barrel, etc. The divider 320 is also provided with a mineral outlet 323, and the mineral outlet 323 is connected to the inlet end of the first material collection device 710. In other words, the mineral sample S divided by the divider 320 flows out from the mineral sample outlet 322, and another part of the mineral flows out from the mineral outlet 323 and enters the first material collection device 710. Optionally, the first material collection device 710 can seal the minerals and set a password to facilitate the subsequent manual collection of minerals from the first material collection device 710 for testing.

[0062] According to this embodiment, the first collecting device 710 is used to separately seal the minerals flowing out of the reducer 320, so as to facilitate subsequent separate testing of this part of the minerals.

[0063] Of course, in other embodiments, the sample preparation device 300 may not be provided with the first material collecting device 710 , and the minerals flowing out of the mineral outlet 323 of the reducer 320 may directly fall onto the vehicle body 100 .

[0064] In an optional embodiment, the size of the mineral sample S after being reduced by the reducer 320 is less than 6 mm.

[0065] With such configuration, the size of the mineral sample S falling into the conveying device 500 is smaller, thereby preventing the volume of the mineral sample S from being too large, which may cause an irregular mineral flow and further avoid affecting the detection accuracy of the detection device 500 .

[0066] Of course, in other embodiments, the size of the mineral sample S after being reduced by the reducer 320 may be larger than 6 mm.

[0067] In the scheme of this application, reference is made to Figure 1 As shown, the mineral detection vehicle further includes a hopper 400, the inlet end of the hopper 400 is connected to the outlet end of the sample preparation device 300, and the outlet end of the hopper 400 is opposite to the feed end of the conveying device 500. Optionally, the hopper 400 is located between the sample preparation device 300 and the conveying device 500, and further optionally, the hopper 400 is located between the mineral sample outlet 322 of the reducer 320 and the feed end of the conveying device 500. The hopper 400 is provided with a detection element 410, which can be located on the inner wall surface of the hopper 400, and the detection element 410 is used to detect the weight of the mineral sample S in the hopper 400. The outlet end of the hopper 400 is provided with a control valve 420, and the control valve 420 is connected to the detection element 410 in communication. Among them, the control valve 420 can be a solenoid valve, or other types of control valves 420.

[0068] When the detection element 410 detects that the weight of the mineral sample S is within the preset range, it means that the weight of the mineral sample S is large, the control valve 420 is in an open state, and the mineral sample S in the hopper 400 enters the conveying device 500; when the detection element 410 detects that the weight of the mineral sample S is within the preset range, it means that the weight of the mineral sample S is small, and the control valve 420 is in a closed state, and the mineral sample S in the hopper 400 cannot enter the conveying device 500.

[0069] It should be noted that the preset range is the weight range of the mineral sample S set by the user according to needs.

[0070] Since the detection device 600 has certain requirements for the amount of minerals to be detected in a single test, if the amount of mineral sample S transported by the conveying device 500 is small and the weight of the mineral sample S is small, it will cause the mineral flow to be unable to form, the mineral flow to be interrupted, etc., which will further affect the detection results. Therefore, this embodiment sets the hopper 400, the detection element 410 and the switch valve to make the weight of the mineral sample S falling into the conveying device 500 within the preset range, avoid the weight of the mineral sample S being too large or too small, ensure the smooth formation of the mineral flow, and help improve the accuracy of the detection results. In addition, the detection element 410 is connected to the control valve 420 in communication, so that when the weight of the mineral sample S is within the preset range, the control valve 420 can be opened in time and quickly to ensure that the mineral sample S enters the conveying device 500 in time, saving reaction time and improving detection efficiency.

[0071] Of course, in other embodiments, the detection element 410 and the control valve 420 may not be in communication connection, and the user may manually control the control valve 420 according to the detection result of the detection element 410 .

[0072] In an optional embodiment, the detection element 410 includes a relative photoelectric transmitter and a photoelectric receiver, the photoelectric transmitter is used to emit laser, the photoelectric receiver is used to receive the laser emitted by the photoelectric transmitter, the photoelectric receiver is communicatively connected to the control valve 420, and when the laser emitted by the photoelectric transmitter is blocked by the mineral sample S, the control valve 420 is in an open state.

[0073] Specifically, the photoelectric transmitter and the photoelectric receiver are both photoelectric sensors, which are relatively arranged on the inner wall surface of the hopper 400. When the weight of the mineral sample S in the hopper 400 is less than the preset range, it means that the weight and volume of the mineral sample S are small, and the mineral sample S will not block the laser. At this time, the photoelectric receiver can successfully receive the laser emitted by the photoelectric transmitter, and the control valve 420 is in a closed state; when the weight of the mineral sample S in the hopper 400 is within the preset range, it means that the weight of the mineral sample S meets the requirement. At this time, the volume of the mineral sample S is large, and the mineral sample S will block the laser. At this time, the laser emitted by the photoelectric receiver is blocked by the mineral sample S, the control valve 420 is in an open state, and the mineral sample S in the hopper 400 enters the conveying device 500.

[0074] In this embodiment, the detection element 410 adopts a through-beam photoelectric sensor, which has a long service life and a short response time, and is conducive to the timely opening of the control valve 420 without direct contact with the mineral sample S.

[0075] In another embodiment, the detection element 410 is a weight sensor, which can convert the mass signal of the mineral sample S into a measurable electrical signal. When the weight sensor detects that the weight of the mineral sample S reaches a preset weight value, it means that the weight of the mineral sample S is large, and the weight of the mineral sample S is within a preset range. The control valve 420 is in an open state, and the mineral sample S in the hopper 400 enters the conveying device 500. When the weight sensor detects that the weight of the mineral sample S is less than the preset weight value, it means that the weight of the mineral sample S is small, and the mass of the mineral sample S is not within the preset range. The control valve 420 is in a closed state, and the mineral sample S in the hopper 400 cannot enter the conveying device 500.

[0076] With this embodiment, the weight sensor has high accuracy and strong stability. By detecting the weight of the mineral sample S, it can directly feedback whether the weight of the mineral sample S is within a preset range, which is convenient for directly judging whether the weight of the mineral sample S meets the requirements.

[0077] Of course, the detection element 410 may also be an element for detecting other physical quantities, and use other principles to feedback the weight of the mineral sample S in the hopper 400 .

[0078] In an optional embodiment, the preset range is 10 Kg-15 Kg.

[0079] With such configuration, the weight of the mineral sample S falling into the conveying device 500 is within the range of 10 Kg-15 Kg, so the weight of the mineral sample S is within a relatively suitable range, thereby preventing the mineral sample S falling into the conveying device 500 from being too heavy or too light.

[0080] Of course, in other embodiments, the maximum value and the minimum value of the preset range may also be other values.

[0081] In an alternative embodiment, reference Figure 2 As shown, the mineral detection vehicle further includes a vibrator 430, which is disposed on the side wall of the hopper 400. Optionally, the vibrator 430 can be fixed to the side wall of the hopper 400 by bonding, welding, etc. When the vibrator 430 is working, it can drive the hopper 400 to vibrate, thereby vibrating the mineral sample S in the hopper 400.

[0082] In this embodiment, the vibrator 430 is added to generate high-frequency vibration, which is conducive to the mineral sample S in the hopper 400 falling into the conveying device 500 smoothly, and avoids the situation where the mineral sample S sticks to the wall of the hopper 400 and causes blockage.

[0083] Of course, in other embodiments, the mineral detection vehicle may not be provided with the vibrator 430 , or the vibrator 430 may be installed at other positions of the hopper 400 .

[0084] In an alternative embodiment, reference Figure 3 As shown, the mineral detection vehicle further includes a rectifying device 510 , which is used to rectify the mineral sample S. The rectifying device 510 is located between the detection device 600 and the sample preparation device 300 .

[0085] In this embodiment, the rectifying device 510 rectify the mineral sample S, which is beneficial to improving the density, stability and flatness of the mineral sample S. Moreover, the mineral sample S falling into the conveying device 500 is first rectified by the rectifying device 510 and then passes through the detection process of the detection device 600. Therefore, the detection device 600 detects the mineral sample S in a regular state, which is more conducive to improving the detection accuracy.

[0086] Of course, in other embodiments, the mineral detection vehicle may not be provided with the rectifying device 510 , and the mineral sample S is placed regularly on the conveying device 500 before the conveying device 500 conveys the mineral sample S to ensure that the mineral sample S400 conveyed by the conveying device 500 is regular.

[0087] In an optional embodiment, reference Figure 4 As shown, the rectifying device 510 includes a rectifying member 511, and the rectifying member 511 is provided with a rectifying surface for flattening the mineral sample S, and the rectifying surface is a plane. When the rectifying member 511 rectify the mineral sample S, the rectifying surface is parallel to the conveying direction of the conveying device 500. Optionally, the rectifying member 511 may be a bent structure or a curved structure. The embodiment of the present application does not limit the structure of the rectifying member 511, as long as the rectifying member 511 has a rectifying surface capable of flattening the mineral sample S. In this embodiment, the mineral sample S is flattened by the rectifying surface of the rectifying member 511 , so the contact area between the rectifying member 511 and the mineral sample S is larger, which is more conducive to the rectifying member 511 flattening the mineral sample S and improving the rectifying effect.

[0088] Optionally, the flow straightener 511 may include a guide scraper, which is used to divert the accumulated mineral sample S and limit the height of the mineral sample S to a value or a range of values ​​greater than 11 cm, such as 5 cm-7 cm, 4 cm-8 cm, 3 cm-9 cm, 2 cm-10 cm, 1 cm-11 cm, or a value greater than 11 cm, to avoid blockage caused by the middle part of the mineral sample S being raised. In one example, the guide scraper limits the height of the mineral sample S to 6 cm; the flow straightener 511 may also include a shaping scraper, which preliminarily shapes the mineral sample S so that the cross-section of the mineral sample S reaches a preset width range, such as 6 cm-8 cm, 5 cm-9 cm, 4 cm-10 cm, 3 cm-11 cm, 2 cm-12 cm, 1 cm-13 cm, or a value or a range of values ​​greater than 13 cm. The height is another range of values, such as 3cm-5cm or 2cm-6cm or 1cm-7cm, or a value or a range of values ​​greater than 7cm. In one example, further optionally, after being shaped by the shaping scraper, the width of the cross section of the mineral sample S is 7cm and the height is 4cm.

[0089] In another embodiment, reference Figure 5 As shown, the rectifying device 510 includes a support member 513 and a pressure roller 512. The support member 513 serves as a mounting base for the pressure roller 512. The support member 513 can be connected to the conveying device 500 or to other components, and the relative position of the pressure roller 512 and the conveying device 500 can be fixed. The pressure roller 512 is rotatably arranged on the support member 513, and the pressure roller 512 is used to contact the mineral sample S to flatten the mineral sample S. Optionally, one of the pressure roller 512 and the support member 513 is provided with an axial hole, and the other is provided with a rotating shaft, the rotating shaft extends into the axial hole, and the rotating shaft and the axial hole are rotatably matched, so that the pressure roller 512 can rotate relative to the support member. Further optionally, the pressure roller 512 is rotatably arranged on the support member 513 through a bearing 514.

[0090] In this embodiment, the mineral sample S is flattened by the rolling process of the pressure roller 512. There is rolling friction between the pressure roller 512 and the mineral sample S, which reduces the friction between the rectification device 510 and the mineral sample S, facilitates the rectification device 510 to smoothly flatten the mineral sample S and improves the rectification effect.

[0091] In a further embodiment, the number of the pressing rollers 512 is at least two, and the pressing rollers 512 are arranged at intervals along the conveying direction A of the conveying device, and each pressing roller 512 is respectively in contact with the mineral sample S conveyed by the conveying device 500. Moreover, in the conveying direction, the height of each pressing roller 512 decreases, that is, of any two adjacent pressing rollers 512, the height of the pressing roller 512 located downstream is less than the height of the pressing roller 512 located upstream. In other words, after the mineral sample S is rolled by the pressing roller 512 located upstream, it is further rolled by the pressing roller 512 located downstream.

[0092] Optionally, there are two rollers 512, the roller 512 located downstream is 0.3 cm -1 cm lower than the roller 512 located upstream, the roller 512 located upstream compresses the mineral sample S to a first thickness, and the roller 512 located downstream further compresses the mineral sample S to a second thickness, the second thickness is less than the first thickness, and the difference between the first thickness and the second thickness can be a preset thickness range, for example, 0.3 cm -1 cm, or 0.2 cm -1.1 cm, 0.1 cm -1.2 cm, or a value or a range of values ​​greater than 1.2 cm. In one example, the roller 512 located downstream is 0.5 cm lower than the roller 512 located upstream, the first thickness can be 3 cm -4 cm, and the second thickness can be 2.5 cm -3.5 cm. In short, by setting the height position of the roller 512, the mineral sample S can be rolled to the desired thickness step by step.

[0093] With this embodiment, the number of pressing rollers 512 is increased, and any position of the mineral sample S is flattened by at least two pressing rollers 512. The height of each pressing roller 512 is different, so the mineral sample S can reach the required compression ratio through step-by-step rolling, which is more conducive to making the mineral sample S flatter and improving the rectification effect.

[0094] Optionally, refer to Figure 6 As shown, the transmission connection between two adjacent rollers 512 is realized through a transmission assembly 530, and the transmission assembly 530 includes a transmission chain 531 and a transmission wheel 532, one of the rollers 512 is driven by a driving device 520 such as a driving motor, and the ends of the two adjacent rollers 512 are provided with a transmission wheel 532, and the transmission chain 531 is used to cooperate with each transmission wheel 532. In this way, when the driving device 520 drives one of the rollers 512 to rotate, the other roller 512 is driven to rotate through the transmission wheel 532 and the transmission chain 531, and the rotation speed of the roller 512 is equal to the rotation speed of the transmission chain 531. Among them, the transmission wheel 532 can be a sprocket, and of course, the transmission chain 531 can be replaced by a synchronous belt. In this case, the transmission wheel 532 is a pulley, which can realize the transmission connection between the two adjacent rollers 512.

[0095] Of course, in other embodiments, the number of the pressing rollers 512 may also be only one.

[0096] In this embodiment, with reference to Figure 6 As shown, the rectifying device 510 is provided with a rectifying member 511 and pressing rollers 512 at the same time, and the rectifying member 511 includes a guiding scraper and a shaping scraper at the same time. The guiding scraper, the shaping scraper and the pressing rollers 512 are arranged at intervals along the conveying direction of the conveying device. The cross sections of the guiding scraper and the shaping scraper are both in the shape of "冂". Any one of them separately limits the width and height of the mineral sample at the same time. Among them, in the conveying direction of the conveying device, the width of the guiding scraper is constant, the shaping scraper is in a tapered shape and the width gradually decreases. The width of the guiding scraper is greater than or equal to the width at the inlet of the shaping scraper, and the height of the guiding scraper is greater than the height at the inlet of the shaping scraper. To prevent the mineral sample from accumulating at the junction of the two, a baffle inclined towards the guiding scraper and extending upwards is arranged on the upper side of the shaping scraper, and the height at the outlet of the shaping scraper is greater than the height of the rolling surface of the pressing rollers 512. With such a setting, the guiding scraper and the shaping scraper preliminarily shape the mineral sample, so that the height of the mineral sample is suitable for rolling by the pressing rollers 512.

[0097] In the solution of the present application, the mineral detection vehicle further includes a control device 800. The control device 800 is arranged on the vehicle body 100, and the control device 800 is respectively in communication connection with the sampling arm 200, the sample preparation device 300, the conveying device 500 and the detection device 600. The control device 800 may be a control device 800 such as a single-chip microcomputer or a programmable logic controller.

[0098] Optionally, the control device 800 is respectively in communication connection with the detection element 410 and the control valve 420. The control device 800 controls the control valve 420 according to the information detected by the detection element 410; the control device 800 controls the movement process of the sampling arm 200; the conveying device 500 provides conveying power through a motor, and the control device 800 is in communication connection with the motor to control the working state of the motor, and further control whether the conveying device 500 conveys the mineral sample S; the control device 800 is respectively in communication connection with the crusher 310 and the riffle 320 to control whether the crusher 310 performs the crushing process and control whether the riffle 320 performs the riffling process; the control device 800 is respectively in communication connection with the near-infrared light detection module 610 and the X-ray fluorescence detection module 620 to control whether each detector starts the detection process.

[0099] By adopting this embodiment, the control device 800 is used to control the sampling arm 200, the sample preparation device 300, the conveying device 500 and the detection device 600 respectively. The mineral detection vehicle automatically realizes each process of sampling, sample preparation, conveying and detection, the degree of automation is improved, manual participation is not required, and manpower is saved.

[0100] Optionally, the control device 800 can be connected to a network, which may be a 5G network, to save and upload the detection results of each detector of the detection device 600 in real time for user viewing.

[0101] In an optional embodiment, the vehicle body 100 is electrically connected to the sampling arm 200, the sample preparation device 300, the conveying device 500 and the detection device 600, and the computer of the vehicle body 100 is used to power each component. In other words, the sampling arm 200, the sample preparation device 300, the conveying device 500 and the detection device 600 can only work when the vehicle body 100 is working. In another embodiment, the mineral detection vehicle further includes a battery module 900, which may be a battery pack. The battery module 900 is disposed on the vehicle body 100, and the battery module 900 is electrically connected to the sampling arm 200, the sample preparation device 300, the conveying device 500, and the detection device 600, respectively, so as to detect the mineral sample S when the vehicle body 100 is not working. When the engine of the vehicle body 100 is not working, the battery module 900 can power the sampling arm 200, the sample preparation device 300, the conveying device 500, and the detection device 600, so as to smoothly realize the sampling, sample preparation, conveying, and detection processes. In other words, the sampling arm 200, the sample preparation device 300, the conveying device 500, and the detection device 600 may not use the electrical energy of the vehicle body 100 itself, so each component is not restricted by whether the vehicle body 100 is working.

[0102] Optionally, the battery module 900 is electrically connected to the sampling arm 200, the crusher 310, the reducer 320, the conveying device 500, the detection element 410, the near-infrared light detection module 610 and the X-ray fluorescence detection module 620, respectively. When the control valve 420 is a solenoid valve, the battery module 900 can also be electrically connected to the solenoid valve. In short, the battery module 900 supplies power to various devices for sampling, sample preparation, transportation and detection.

[0103] Since the engine of the vehicle body 100 is in a vibrating state when it is working, detection in this state will affect the detection structure. Therefore, the present embodiment separately adds a battery module 900, and the battery module 900 separately supplies power to each electrical component to realize detection in a vibration-free state, which is beneficial to improve the detection accuracy.

[0104] In an optional embodiment, the mineral detection vehicle also includes a second collecting device 720, which can be a collecting box, a collecting hopper, a collecting barrel or other structures. Along the conveying direction of the conveying device 500, the inlet end of the second collecting device 720 is opposite to the discharge end of the conveying device 500, so that the mineral sample S conveyed by the conveying device 500 enters the second collecting device 720.

[0105] Optionally, the second collecting device 720 can be directly located below the discharge end of the conveying device 500, and the mineral sample S conveyed by the conveying device 500 directly falls into the second collecting device 720; or, the second collecting device 720 can be located at other positions of the discharge end of the conveying device 500, and the discharge end of the conveying device 500 is connected to the second collecting device 720 through a third connecting piece, so that the mineral sample S conveyed by the conveying device 500 enters the second collecting device 720.

[0106] According to this embodiment, after the detection of the mineral sample S is completed, the second collecting device 720 is used to separately contain the mineral sample S, so as to facilitate the subsequent use of the mineral sample S and avoid the waste of the mineral sample S.

[0107] Of course, in other embodiments, the mineral detection vehicle may not be provided with the second collecting device 720, and the mineral sample S flowing out of the discharge end of the conveying device 500 may directly fall onto the vehicle body 100, and then be processed separately after the subsequent detection is completed.
