Description

Technical Field

[0001] This application relates to the technical field of coal mine material separation, and particularly to a detection and identification device for irregular materials. Background Art

[0002] In the coal mine industry, the separation range of irregular materials is very wide. Among them, coal gangue sorting is a pre-combustion treatment technology for coal, which is an indispensable link in coal mine production and one of the effective methods to improve coal quality. Since coal and gangue are mixed together during the transmission process, it is necessary to identify coal and gangue before sorting the gangue, so as to accurately sort the gangue in coal during the coal and gangue transmission process. Nowadays, the separation range of coal mine materials is gradually increasing. When meeting the separation effect of larger materials, it is also necessary to ensure the separation accuracy of small materials passing through the separation range. In the prior art, a detection device is often set on the conveyor belt to detect and identify the coal gangue passing through the detection device on the conveyor belt. However, since the coal gangue on the conveyor belt is often arranged irregularly on the conveyor belt before entering the identification and detection equipment, and the detection device is often set at the center position of each conveyor belt, only the coal gangue at the center position can be detected, while the side position forms an identification blind area, resulting in some smaller scattered stones being easily directly passed through the identification blind area. This part of the coal gangue cannot be identified and detected, making the subsequent sorting difficult and the sorting efficiency low. Summary of the Invention

[0010] Both sides of the first mounting platform are movably connected to the mounting frame through two first adjusting beams respectively, and both sides of the second mounting platform are movably connected to the mounting frame through two second adjusting beams respectively.

[0011] In a possible implementation manner, it further includes an adjusting component;

[0012] The first adjusting beam and the second adjusting beam are respectively movably connected to the mounting frame through the adjusting component, and the adjusting component is suitable for locking after adjusting the first adjusting beam and the second adjusting beam in place.

[0013] In a possible implementation manner, it further includes a first reinforcing plate and a second reinforcing plate;

[0014] The first reinforcing plate is connected to the two first adjusting beams and is suitable for providing support for the first mounting platform;

[0015] The second reinforcing plate is connected to the two second adjusting beams and is suitable for providing support for the second mounting platform.

[0016] In a possible implementation manner, the ultrasonic detector is located on one side of the nuclear source detector.

[0017] In a possible implementation manner, a first through hole is opened at the bottom of the first mounting platform, and the detection end of the ultrasonic detector and the detection end of the nuclear source detector face the first through hole; a second through hole is opened at the top of the second mounting platform, and the detection end of the nuclear source outputter faces the second through hole.

[0019] The ultrasonic detectors and the nuclear source detectors are arranged in a column along the body length direction of the first mounting platform, and the ultrasonic detectors in one column and the nuclear source detectors in one column are staggeredly distributed relative to the ultrasonic detectors in the previous column and the nuclear source detectors in the previous column.

[0020] In a possible implementation manner, there are more than two lifting lugs provided at the top of the mounting frame.

[0021] In a possible implementation manner, a top cover for opening or closing the first installation platform is provided on the top of the first installation platform.

[0049] In addition, for better illustration of the present application, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0050] The present application provides a detection and identification device for irregular materials, such as Figures 1 to 11As shown in the figure, it includes: a detection device 1000, a mounting rack 2300, a first mounting platform 2100 and a second mounting platform 2200 which are oppositely arranged; the first mounting platform 2100 and the second mounting platform 2200 which are oppositely arranged are mounted on the mounting rack 2300; the conveyor belt is adapted to pass between the first mounting platform 2100 and the second mounting platform 2200, and the plane where the first mounting platform 2100 is located, the plane where the second mounting platform 2200 is located and the conveying surface of the conveyor belt are parallel to each other. The detection device 1000 includes: an ultrasonic detector 1100, a nuclear source detector 1200 and a nuclear source outputter 1300; the nuclear source outputter 1300 is arranged on the second mounting platform 2200, and both the ultrasonic detector 1100 and the nuclear source detector 1200 are arranged on the first mounting platform 2100; the emission ends of the ultrasonic detector 1100, the nuclear source outputter 1300 and the nuclear source detector 1200 all face the conveyor belt, and the emission end of the nuclear source outputter 1300 and the receiving end of the nuclear source detector 1200 are oppositely arranged; there are two or more detection devices 1000, and the two or more detection devices 1000 are arranged in an array.

[0051] It should be noted here that the main body of the mounting frame 2300 is of a rectangular structure. There are two symmetrically arranged mounting frames 2300, which provide a mounting foundation for the first mounting platform 2100 and the second mounting platform 2200. The relatively arranged first mounting platform 2100 and second mounting platform 2200 are located between the two mounting frames 2300. The conveyor belt is suitable for conveying irregular materials (irregular materials are coal and gangue mixed together). The ultrasonic detector 1100 is suitable for detecting the irregular materials passing between the first mounting platform 2100 and the second mounting platform 2200. The detection end of the ultrasonic detector 1100 emits a signal, and the signal is reflected by the irregular materials below and then received by the receiving end of the ultrasonic detector. The received signal data is uploaded to the host computer for storage, and the signal data stored in the host computer is used as a reference basis for distinguishing the types of irregular materials. Among them, the ultrasonic detector 1100 uses the ultrasonic detector with the model number YJ03-200W in the existing technology. The nuclear source output device 1300 and the nuclear source detector 1200 are suitable for identifying the irregular materials passing between the first mounting platform 2100 and the second mounting platform 2200. The transmitting end of the nuclear source output device 1300 and the receiving end of the nuclear source detector 1200 are arranged opposite to each other. Among them, the nuclear source detector 1200 uses the nuclear source detector with the model number DT03-300 in the existing technology. The nuclear source output device 1300 emits an electrical signal, and the electrical signal penetrates the irregular materials directly above and then is received by the nuclear source detector 1200. Due to the different types of irregular materials, there are differences in the density and thickness of the irregular materials, and the irregular materials will cause different degrees of attenuation to the electrical signal. The attenuated electrical signal is received by the nuclear source detector 1200, and the nuclear source detector 1200 uploads the received electrical signal to the host computer. The host computer can identify the types and thicknesses of the irregular materials (that is, judge whether the irregular materials are coal or gangue) based on the electrical signal received by the nuclear source detector 1200.

[0052] The transmitting end of the nuclear source output device 1300 and the receiving end of the nuclear source detector 1200 are arranged opposite to each other. The transmitting end of the nuclear source output device 1300 is directly aligned with the receiving end of the nuclear source detector 1200, ensuring that the electrical signal emitted by the nuclear source output device 1300 can reach the nuclear source detector 1200 with the shortest path and the least attenuation, improving the receiving efficiency and accuracy of the nuclear source detector 1200.

[0053] Such as Figure 4As shown, the detection devices 1000 arranged in an array can ensure full coverage of the detection area between the first mounting platform 2100 and the second mounting platform 2200, reduce detection blind spots, avoid missed detection of irregular materials, and ensure the detection accuracy. At the same time, two or more detection devices 1000 form a redundant system. Even if one of the detection devices 1000 fails, the remaining detection devices 1000 can still work normally, thus ensuring the continuity and reliability of detection. Multiple detection devices 1000 can effectively improve the recognition accuracy of irregular materials within the material lower limit range and relatively increase the width of a single channel.

[0054] In a possible implementation, as Figures 1 to 3 shown, the main bodies of the first mounting platform 2100 and the second mounting platform 2200 are box structures with open tops. The setting of the box structure provides a relatively enclosed space for the detection devices 1000, reduces the risk of personnel being directly exposed to the radioactive environment, and avoids direct harm to the operators.

[0055] In a possible implementation, as Figures 3 to 7 shown, the nuclear source emitters 1300 are equidistantly arranged along the body width and body length directions of the second mounting platform 2200, and the nuclear source emitters 1300 arranged along the body length direction of the second mounting platform 2200 are staggeredly distributed relative to the nuclear source emitters 1300 in the previous row; the ultrasonic detectors 1100 and the nuclear source detectors 1200 are equidistantly arranged along the body width and body length directions of the first mounting platform 2100, and the ultrasonic detectors 1100 and the nuclear source detectors 1200 arranged along the body length direction of the first mounting platform 2100 are staggeredly distributed relative to the ultrasonic detectors 1100 and the nuclear source detectors 1200 in the previous row.

[0056] It should be noted here that the design of equidistant arrangement of the nuclear source emitters 1300, the ultrasonic detectors 1100, and the nuclear source detectors 1200 helps to ensure the uniform distribution of the identification signals in the entire detection area. Since the electrical signal of each nuclear source emitter 1300 is received only by the nuclear source detector 1200 directly above it, the recognition accuracy is improved and the recognition blind spots are reduced. The subsequent rows of the nuclear source emitters 1300, the ultrasonic detectors 1100, and the nuclear source detectors 1200 are staggeredly distributed relative to the previous row. This staggered design may be to avoid direct interference between adjacent nuclear source emitters 1300, increase the coverage density of the detection area, improve the comprehensiveness and accuracy of detection, effectively improve the recognition accuracy of irregular materials within the material lower limit range, and relatively increase the width of this single channel.

[0057] Preferably, the distance between adjacent two rows of the detection devices 1000 ranges from 66 mm to 680 mm, and the distance between adjacent two columns of the detection devices 1000 ranges from 300 mm to 360 mm. The detection devices 1000 in the latter column are offset by 33 mm relative to the detection devices 1000 in the former column.

[0058] Specifically, as Figure 4 shown, there are 26 detection devices 1000 in total, arranged in a four-row and seven-column form.

[0059] In a possible implementation manner, as Figures 5 to 7 shown, the ultrasonic detector 1100 is located on one side of the nuclear source detector 1200. It should be noted here that there is a mounting seat 2121 on the first mounting platform 2100. The mounting seat 2121 is fixedly arranged on the first mounting platform 2100 through the first fastening bolt 2125. The mounting seat 2121 has a cavity with openings at both ends. The detection end of the ultrasonic detector 1100 and the receiving end of the nuclear source detector 1200 are respectively embedded inside the cavity of the mounting seat 2121, arranging the ultrasonic detector 1100 and the nuclear source detector 1200 together, so as to simultaneously detect irregular materials and identify their types. The ultrasonic detector 1100 and the nuclear source detector 1200 work simultaneously and perform different detection tasks respectively, thereby shortening the overall detection time and improving the detection efficiency.

[0060] Furthermore, as Figure 5 、 Figure 10 、 Figure 11As shown in the figure, it further includes a pre-installation fixing part 2122. The pre-installation fixing part 2122 is provided with a first pre-installation groove 2127 matching the outer contour of the ultrasonic detector 1100 and a second pre-installation groove 2123 matching the outer contour of the nuclear source detector 1200. The ultrasonic detector 1100 is embedded in the first pre-installation groove 2127 and the detection end of the ultrasonic detector 1100 penetrates through the first pre-installation groove 2127. The nuclear source detector 1200 is embedded in the pre-installation groove 2123 and the detection end of the nuclear source detector 1200 penetrates through the second pre-installation groove 2123. The cavity of the mounting seat 2121 matches the outer contour of the pre-installation fixing part 2122, and the pre-installation fixing part 2122 is embedded inside the cavity of the mounting seat 2121. One side of the mounting seat 2121 facing the bottom of the first mounting platform 2100 is provided with a fixing substrate 2124. The main body of the fixing substrate 2124 is in a rectangular plate-like structure. The fixing substrate 2124 is provided with a relief slot hole 2126. The mounting seat 2121 is fixedly arranged in the relief slot hole 2126 of the fixing substrate 2124. The first fastening bolts 2125 respectively penetrate through the four corners of the fixing substrate 2124 and the bottom of the first mounting platform 2100, so as to fixedly install the ultrasonic detector 1100 and the nuclear source detector 1200 inside the cavity of the first mounting platform 2100.

[0061] In a possible implementation manner, as Figure 1 , Figure 3 , Figure 8 , Figure 9 shown, a first through hole 2110 is opened at the bottom of the first mounting platform 2100, and the detection ends of the ultrasonic detector 1100 and the nuclear source detector 1200 face the first through hole 2110; a second through hole 2210 is opened at the top of the second mounting platform 2200, and the detection end of the nuclear source outputter 1300 faces the second through hole 2210. It should be noted here that by providing the first through hole 2110 and the second through hole 2210, it is ensured that the electrical signal emitted by the nuclear source outputter 1300 can smoothly pass through the bottom of the first mounting platform 2100 and the top of the second mounting platform 2200 and then be received by the nuclear source detector 1200, reducing the attenuation and interference in signal transmission, thereby improving the detection accuracy.

[0062] Furthermore, both the first through-holes 2110 and the second through-holes 2210 are arranged in an array, and the detection ends of the ultrasonic detectors 1100 correspond one by one to the detection ends of the nuclear source detectors 1200, and the second through-holes 2210 correspond one by one to the output ends of the nuclear source outputters 1300. This design ensures that each detection device 1000 can accurately align with its predetermined detection area, reduces the detection errors caused by position deviations, and ensures the accuracy and reliability of the detection results. It should be noted here that the aperture of the first through-holes 2110 is larger than that of the second through-holes 2210. Since the detection ends of the ultrasonic detectors 1100 and the nuclear source detectors 1200 are both located in the first through-holes 2110, a larger aperture is required to ensure that the sound waves emitted by the detection ends of the ultrasonic detectors 1100 and the electrical signals received by the detection ends of the nuclear source detectors 1200 can pass freely, avoiding interference with the detection due to the too small aperture of the first through-holes 2110 and ensuring the detection accuracy rate. Preferably, both the first through-holes 2110 and the second through-holes 2210 are circular through-holes. The diameter of the first through-holes 2110 is: 116 mm, and the diameter of the second through-holes 2210 is: 30 mm.

[0063] In a possible implementation manner, as Figures 12 to 16 shown, the nuclear source outputter 1300 includes: a motor 7300, a fixing plate 7700, a rotating cylinder 7400, and a protective shell 7100; an element installation groove 7410 is formed on the outer side wall of the rotating cylinder 7400, and radioactive nuclides are suitable for being placed in the element installation groove 7410; the protective shell 7100 is provided with a cavity with one end open, the fixing plate 7700 is buckled on the open end of the protective shell 7100, the rotating cylinder 7400 is arranged inside the cavity of the protective shell 7100, and the output shaft 7310 of the motor 7300 passes through the fixing plate 7700 and extends into the cavity of the protective shell 7100 to be connected with the rotating cylinder 7400, and is suitable for driving the rotating cylinder 7400 to rotate inside the protective shell 7100 when the output shaft 7310 of the motor 7300 rotates; a radiation hole 7110 is formed at the top of the protective shell 7100, and radioactive nuclides can emit rays outward through the radiation hole 7110.

[0064] Here, it should be noted that since the protective shell 7100 sleeves the rotating cylinder 7400, the rotating cylinder 7400 rotates inside the protective shell 7100, preventing the rotating cylinder 7400 from being exposed outside. The element installation groove 7410 formed on the outer sidewall of the rotating cylinder 7400 is suitable for placing radioactive nuclides. When the element installation groove 7410 is aligned with the radiation hole 7110 on the protective shell 7100, the radioactive nuclides emit rays to the outside through the radiation hole 7110. When the element installation groove 7410 is not aligned with the radiation hole 7110 on the protective shell 7100, the element installation groove 7410 is blocked by the protective shell 7100, and the radioactive nuclides cannot emit rays to the outside. Therefore, by rotating the output shaft 7310 of the motor 7300, the sealing and penetration of the radioactive nuclides can be achieved. When it is not necessary to perform radiation detection on coal, the radioactive nuclides are sealed inside the protective shell 7100. When it is necessary to perform radiation detection on coal, the radioactive nuclides penetrate from the radiation hole 7110. The overall structure of this application is compact, with high startup efficiency and short operation time. It can achieve remote startup and shutdown of the outward radiation of radioactive nuclides. Remote operation effectively reduces the close contact between personnel and radioactive nuclides, reducing the possibility of harm to the human body.

[0065] In a possible implementation manner, the rotating cylinder 7400 rotates around the axis of the rotating cylinder 7400. As Figure 14 shown, the main body of the rotating cylinder 7400 is in a cylindrical structure. The axis of the rotating cylinder 7400 and the axis of the output shaft 7310 are on the same straight line. The output shaft 7310 passes through the central through hole 7430 of the rotating cylinder 7400 and is fixedly connected to the rotating cylinder 7400. Thus, when the output shaft 7310 rotates, the rotating cylinder 7400 rotates together with the output shaft 7310. Further, as Figure 16 shown, a locking key 7311 is provided on the outer sidewall of the output shaft 7310, and a locking hole matching the locking key 7311 is formed on the inner sidewall of the rotating cylinder 7400. The locking key 7311 is inserted into the locking hole to achieve the fixed connection between the rotating cylinder 7400 and the output shaft 7310.

[0066] In a possible implementation manner, the sidewall of the element installation groove 7410 is provided with a threaded structure. An external thread nut 7450 is provided inside the element installation groove 7410. The external thread nut 7450 is fixed to the element installation groove 7410 by means of a threaded connection. When the radioactive nuclides are placed in the element installation groove 7410, the external thread nut 7450 is screwed tightly inside the element installation groove 7410 to limit and fix the radioactive nuclides, preventing the radioactive nuclides from falling out of the element installation groove 7410 when the rotating cylinder 7400 rotates.

[0067] In a possible implementation manner, as Figure 12 and Figure 16As shown, the protective shell 7100 is provided with a first reinforcement hole 7130, and the rotating cylinder 7400 is also provided with a second reinforcement hole 7440. When the element installation groove 7410 overlaps and aligns with the radiation hole 7110, the first reinforcement hole 7130 of the protective shell 7100 and the second reinforcement hole 7440 of the rotating cylinder 7400 rotate to the same orientation and overlap and align. At this time, screws are screwed into the first reinforcement hole 7130 and the second reinforcement hole 7440 to reinforce and lock between the protective shell 7100 and the rotating cylinder 7400, preventing the rotating cylinder 7400 from being misaligned and obstructing the emission of rays.

[0068] In a possible implementation, one end of the rotating cylinder 7400 close to the motor 7300 protrudes with a trigger block 7420. Further, as Figure 14 shown, the trigger block 7420 is a block structure, and its front is in a "T" shape.

[0069] In a possible implementation, as Figure 12 、 Figure 16 shown, the main body of the fixing plate 7700 is a rectangular plate structure. Bolt holes 7710 are provided at the four corners of the fixing plate 7700. The fixing plate 7700 and the protective shell 7100 are fixed together by means of bolt connection.

[0070] In a possible implementation, a first limit switch 7500 is provided on one side of the fixing plate 7700 facing the rotating cylinder 7400. When the trigger block 7420 triggers the first limit switch 7500, the radiation hole 7110 and the element installation groove 7410 are aligned. The detection end of the first limit switch 7500 faces the side where the trigger block 7420 is located. When the trigger block 7420 approaches and triggers the first limit switch 7500, the open end of the element installation groove 7410 faces the inner top of the protective shell 7100 and is opposite to the radiation hole 7110. At this time, the controller controls the motor 7300 to stop moving, and the radionuclide emits rays outward through the radiation hole 7110.

[0071] In a possible implementation, a second limit switch 7600 is provided on one side of the fixing plate 7700 facing the rotating cylinder 7400. When the trigger block 7420 triggers the second limit switch 7600, the radiation hole 7110 and the element installation groove 7410 are misaligned. The detection end of the second limit switch 7600 faces the side where the trigger block 7420 is located. When the trigger block 7420 approaches and triggers the second limit switch 7600, the open end of the element installation groove 7410 faces the inner bottom of the protective shell 7100. At this time, the controller controls the motor 7300 to stop moving, and the radionuclide is completely enclosed inside the protective shell 7100, and the radionuclide cannot emit rays outward.

[0072] Further, the first limit switch 7500 and the second limit switch 7600 are located on the same horizontal plane, and the trigger block 7420 rotates 180 degrees after triggering the first limit switch 7500 before triggering the second limit switch 7600.

[0073] Still further, both the first limit switch 7500 and the second limit switch 7600 adopt the micro limit travel switch KW11-2.

[0074] In a possible implementation, a first stop block 7720 and a second stop block 7730 are provided on the side of the fixing plate 7700 facing the rotating cylinder 7400; as Figures 12 to 16 shown, in order to ensure that the rotating cylinder 7400 does not rotate excessively, the first stop block 7720 is provided above the first limit switch 7500, and the second stop block 7730 is provided above the second limit switch 7600, so that the trigger block 7420 can only rotate between the first stop block 7720 and the second stop block 7730, and when the trigger block 7420 contacts the first stop block 7720, the trigger block 7420 can trigger the first limit switch 7500; when the trigger block 7420 contacts the second stop block 7730, the trigger block 7420 can trigger the second limit switch 7600.

[0075] Further, as Figure 16 shown, the first stop block 7720 and the second stop block 7730 are located on the straight line where the diameter of the rotating cylinder 7400 is located, so the rotating cylinder 7400 can only rotate within 180°.

[0076] In a possible implementation, as Figure 16 shown, a relief groove 7740 is provided on the side of the fixing plate 7700 facing the rotating cylinder 7400, and the first limit switch 7500, the second limit switch 7600, the first stop block 7720, and the second stop block 7730 are all arranged in the relief groove 7740.

[0077] In a possible implementation, a mounting seat 7120 is provided at the bottom of the protective shell 7100. As Figure 12 shown, the main body of the mounting seat 7120 is in a rectangular plate-like structure, and both ends of the mounting seat 7120 protrude from both sides of the bottom of the protective shell 7100. Bolt holes 7121 are provided in the mounting seat 7120, and the whole device can be stably installed at the bottom of the second mounting platform 2200 by means of bolt connection.

[0078] Further, the model of the motor 7300 is ZS-F187.91.

[0079] In a possible implementation, it further includes: a motor housing 7200; the motor housing 7200 and the protective housing 7100 are respectively located on opposite sides of a fixing plate 7700, and a motor 7300 is disposed inside the cavity of the motor housing 7200. As Figure 12 shown, the main body of the motor housing 7200 is in a cuboid structure. The motor housing 7200 is provided with a cavity with one end open. The open end of the motor housing 7200 is buckled on the side of the fixing plate 7700 connecting the motor 7300. The motor housing 7200 is applicable to isolate and protect the motor 7300.

[0080] In a possible implementation, both the first mounting platform 2100 and the second mounting platform 2200 are movably connected to the mounting frame 2300. Both the first mounting platform 2100 and the second mounting platform 2200 can move in a direction towards or away from the conveyor belt, and are applicable to adjust the distance between the first mounting platform 2100 and the second mounting platform 2200. It should be noted here that both the first mounting platform 2100 and the second mounting platform 2200 can move in a direction towards or away from the conveyor belt, so that the first mounting platform 2100 and the second mounting platform 2200 approach or move away from each other. By adjusting the distance between the first mounting platform 2100 and the second mounting platform 2200, it is ensured that irregular materials of different sizes can pass between the first mounting platform 2100 and the second mounting platform 2200, so that the detection and recognition device for irregular materials of the present invention can adapt to different detection working conditions, thereby improving the working efficiency.

[0081] Further, as Figure 1 、 Figure 2 shown, the mounting frame 2300 includes two relatively arranged frames. The main body of the frame is in a rectangular structure. The frame is formed by enclosing two vertical beams 2310 and two cross beams. The length direction of the vertical beam 2310 is perpendicular to the length direction of the cross beam. The rectangular frame structure makes the mounting frame 2300 not easily deformed or collapsed when bearing external loads, ensuring the safety and reliability of the overall structure. Preferably, the two cross beams include a first cross beam 2320 and a second cross beam 2322. The first cross beam 2320 and the vertical beam 2310 are both made of U-shaped steel, and the second cross beam 2322 is made of L-shaped angle iron.

[0082] In a possible implementation, as Figure 1 、 Figure 2 shown, it further includes: two first adjusting beams 2340 and two second adjusting beams 2350; both sides of the first mounting platform 2100 are movably connected to the mounting frame 2300 through two first adjusting beams 2340 respectively, and both sides of the second mounting platform 2200 are movably connected to the mounting frame 2300 through two second adjusting beams 2350 respectively.

[0083] It should be noted here that the first mounting platform 2100 and the second mounting platform 2200 move along the longitudinal direction of the vertical beam 2310 of the mounting frame 2300 through two first adjusting beams 2340 and two second adjusting beams 2350 movably arranged on the mounting frame 2300. That is, the first mounting platform 2100 and the second mounting platform 2200 are movably mounted on the mounting frame 2300 through the two first adjusting beams 2340 and the two second adjusting beams 2350. By adjusting the mounting positions of the two first adjusting beams 2340 and the two second adjusting beams 2350 on the mounting frame 2300, the distance between the first mounting platform 2100 and the second mounting platform 2200 is adjusted, so as to ensure that irregular materials of different sizes can pass between the first mounting platform 2100 and the second mounting platform 2200.

[0084] Furthermore, the two first adjusting beams 2340 and the two second adjusting beams 2350 are respectively movably connected to the vertical beam 2310 of the mounting frame 2300. The longitudinal directions of the two first adjusting beams 2340 and the longitudinal directions of the two second adjusting beams 2350 are all perpendicular to the longitudinal direction of the vertical beam 2310. The first adjusting beam 2340 and the second adjusting beam 2350 are both made of angle steel. The first adjusting beam 2340 and the second adjusting beam 2350 are respectively suitable for providing stable support for the first mounting platform 2100 and the second mounting platform 2200. The openings of the two first adjusting beams 2340 face each other. The first mounting platform 2100 is placed in the openings of the two first adjusting beams 2340 and the first mounting platform 2100 is in close contact with the two first adjusting beams 2340. The openings of the two second adjusting beams 2350 face each other. The second mounting platform 2200 is placed in the openings of the two second adjusting beams 2350 and the second mounting platform 2200 is in close contact with the two second adjusting beams 2350. By adjusting the positions of the two first adjusting beams 2340 and the two second adjusting beams 2350 on the vertical beam 2310 of the mounting frame 2300, the first mounting platform 2100 and the second mounting platform 2200 are driven to approach or move away from each other, which is suitable for adjusting the distance between the first mounting platform 2100 and the second mounting platform 2200.

[0085] Preferably, the top of the second mounting platform 2200 is in contact with the lower surface of the conveyor belt. This contact design can minimize the gap between the second mounting platform 2200 and the conveyor belt. The electrical signal emitted by the nuclear source emitter 1300 can directly penetrate the conveyor belt, ensuring that the electrical signal can be received by the nuclear source detector 1200 with the shortest path and the least attenuation, and improving the detection accuracy of the detection device 1000 for the irregular materials on the conveyor belt.

[0086] In a possible implementation, it further includes an adjusting component 3000; the first adjusting beam 2340 and the second adjusting beam 2350 are respectively movably connected to the mounting bracket 2300 through the adjusting component 3000, and the adjusting component 3000 is adapted to lock the first adjusting beam 2340 and the second adjusting beam 2350 after they are adjusted in place.

[0087] It should be noted here that, as Figures 1 to 7 shown, first adjusting holes 2311 and second adjusting holes 2312 are provided on the four vertical beams 2310 of the mounting bracket 2300. Both the first adjusting holes 2311 and the second adjusting holes 2312 are in the shape of long strip openings, and the first adjusting holes 2311 and the second adjusting holes 2312 are arranged along the body length direction of the vertical beam 2310. A first mounting hole 2341 corresponding to the first adjusting hole 2311 is provided on the side of the first adjusting beam 2340 that is in contact with the vertical beam 2310. The adjusting component 3000 is arranged through the first mounting hole 2341 and the first adjusting hole 2311. The adjusting component 3000 moves in the first adjusting hole 2311 to drive the first adjusting beam 2340 to move, thereby adjusting the position of the first adjusting beam 2340 on the vertical beam 2310. After that, the adjusting component 3000 fixes and locks the first adjusting beam 2340 and the vertical beam 2310, so as to lock the first adjusting beam 2340 on the vertical beam 2310. A second mounting hole 2351 corresponding to the second adjusting hole 2312 is provided on the side of the second adjusting beam 2350 that is in contact with the vertical beam 2310. The adjusting component 3000 is arranged through the second mounting hole 2351 and the second adjusting hole 2312. The adjusting component 3000 moves in the second adjusting hole 2312 to drive the second adjusting beam 2350 to move, thereby adjusting the position of the second adjusting beam 2350 on the vertical beam 2310. After that, the adjusting component 3000 fixes and locks the second adjusting beam 2350 and the vertical beam 2310, so as to lock the second adjusting beam 2350 on the vertical beam.

[0088] By providing the adjusting component 3000, the distance between the first adjusting beam 2340 and the second adjusting beam 2350 after adjustment is locked, so as to prevent the distance between the first mounting platform 2100 and the second mounting platform 2200 from changing during use, ensuring that irregular materials of different sizes can pass between the first mounting platform 2100 and the second mounting platform 2200. The adjusting component 3000 locks the adjusted first adjusting beam 2340 and second adjusting beam 2350, preventing the first adjusting beam 2340 and the second adjusting beam 2350 from shifting during use, and ensuring the stability of the first adjusting beam 2340 and the second adjusting beam 2350 during use.

[0089] Further, the adjusting assembly 3000 includes a third bolt and a third nut. The third bolt sequentially passes through the first mounting hole 2341 and the first adjusting hole 2311. After the third bolt moves in the first adjusting hole 2311 to drive the first adjusting beam 2340 to move and thus adjust the position of the first adjusting beam 2340 on the vertical beam 2310, the third nut is tightened to lock the first adjusting beam 2340 on the vertical beam 2310. Using the third bolt and the third nut as the adjusting assembly 3000, the structure is simple and easy to install and disassemble, reducing the structural complexity and ensuring the stability of the overall structure.
