Description

Technical Field

[0001] The present invention relates to the technical field of coal gangue separation, and in particular to a coal gangue separation device based on the fusion of visible light cameras and X-rays. Background Art

[0002] A coal gangue separation device is a mechanical device used to effectively separate coal and coal gangue; during coal mining and processing, coal gangue is often mixed in coal, and the presence of coal gangue will affect the quality of coal and increase transportation costs, etc. Through the separation device, the two can be accurately distinguished, improving the utilization efficiency and quality of coal resources.

[0003] Existing coal gangue separation devices usually only adopt a single visible light machine vision solution or a dual-energy X-ray imaging solution alone. Among them, the single visible light machine vision solution will result in limited accuracy. Relying solely on visible light machine vision, it is difficult to comprehensively and accurately identify coal gangue and coal. Moreover, visible light machine vision has strict requirements for ambient light. Too strong, too weak or uneven light will interfere with image acquisition and analysis. Moreover, dust is easily attached to the surface of the material and diffuses in the air, affecting light transmission, resulting in blurred images and difficult feature extraction, seriously affecting the continuous, stable and accurate operation of the separation device and being unable to well adapt to the complex and changeable on-site environment; while the single dual-energy X-ray imaging solution has the defect of single function. In actual situations, the composition and structure of coal gangue and coal are relatively complex, there are cases where the densities are similar, or there are other interfering factors affecting density judgment. Relying solely on this solution, it is difficult to accurately and comprehensively achieve separation, and it is easy to have the phenomenon of separation errors or omissions.

[0004] In view of this, the present application proposes a coal gangue separation device based on the fusion of visible light cameras and X-rays, which integrates the design scheme of a coal gangue separation device with a visible light machine vision solution + a dual-energy X-ray imaging solution, and can ensure independent imaging between the two without interfering with each other's imaging.

[0016] Compared with the prior art, the present invention provides a coal gangue sorting device based on the fusion of a visible light camera and X-rays, having the following beneficial effects: 1. For the coal gangue sorting device based on the fusion of a visible light camera and X-rays, an X-ray imaging module and a visible light imaging module are installed above the coal gangue sorter to collect visible light images of coal gangue and ore sorting. It has a high visual imaging accuracy and a fast scanning speed, and can still capture high-definition surface images of coal and gangue under harsh working conditions; it ensures independent imaging between the two and will not interfere with each other's imaging.

[0017] 2. For the coal gangue sorting device based on the fusion of a visible light camera and X-rays, it can make the converging light paths emitted by the two strip light source generators fuse on the optimal imaging plane of the line scan camera.

For the coal gangue sorting device based on the fusion of a visible light camera and X-rays, by rotating the threaded rod, while the threaded rod rotates, it is threadedly connected to the T-shaped block, which can drive the strip light source generator to move, thereby adjusting the height of the strip light source generator. Rotate the knob to move the strip light source generator to an appropriate angle, and then limit and fix it through the pawl, thus completing the angle adjustment of the strip light source generator, making it more convenient to use.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0023] Embodiment 1: Refer to Figures 1 - 9 , a coal gangue separation device based on the fusion of a visible light camera and X-rays, including a support 1, a conveyor belt 202 is arranged on the support 1, and further includes support legs 3 fixedly arranged on the support 1. A top plate 301 is arranged on the support legs 3, an X-ray emitter 302 is arranged on the top plate 301, and a detector 304 is also arranged between the surrounding conveyor belts 202, and the detector 304 is fixedly connected to the support 1; a vertical plate 305 is fixedly connected to the top plate 301, and a line scan camera 403 is fixedly connected to the vertical plate 305; a U-shaped frame 4 is fixedly arranged on the support 1, and a strip light source generator 402 cooperating with the line scan camera 403 is slidably arranged on the U-shaped frame 4.

[0024] A flared opening 303 is arranged at the bottom of the X-ray emitter 302, a ray receiving port is arranged on the detector 304, and the ray beam generated by the X-ray emitter 302 is emitted through the flared opening 303, and then penetrates the conveyor belt 202 and is received through the ray receiving port above the detector 304.

[0025] In this embodiment, an X-ray imaging module and a visible light imaging module are installed above the coal gangue separator. Specifically, the X-ray emitter 302 is installed above the conveyor belt 202, and the detector 304 is fixedly connected to the support 1 and is located between the surrounding conveyor belts 202. During use, the X-ray emitter 302 generates X-rays through electromagnetic excitation. The rays pass through the lower flared opening 303 to generate a fan-shaped ray beam, as Figure 8 shown. The ray beam penetrates the lower conveyor belt 202 and is then irradiated on the X-ray imaging array through the ray receiving port above the detector 304 to form a digital image of the projected rays; moreover, before use, the height of the strip light source generator 402 on the U-shaped frame 4 can be adjusted. After the adjustment is completed, the visible light imaging module can start to work. Refer to Figure 9, it can make the converging optical paths emitted by the two strip light source generators 402 converge on the best imaging surface of the line scan camera 403. Specifically, the line scan camera 403 selects a high-precision color camera, which can image more clearly and reflect the relevant textures on the surface of the object. At the same time, combined with the installation angles of the two strip light source generators 402, it reduces the specular reflection and light reflection interference of the crystals on the surface of the coal gangue stone object. The imaging is softer and more uniform than that of the area array camera, and is equipped with a large-depth-of-field lens, ensuring a certain depth of field and making the particle size range of coal gangue separation wider.

[0026] In this application, the visible light imaging system and the X-ray imaging system are sequentially installed above the main conveyor belt 202 of the coal gangue separation equipment in order and without affecting each other's imaging. When the conveyor belt 202 is started, the line scan camera 403 cooperates with the strip light source generator 402 to collect visible light images, and the X-ray emitter 302 and the detector 304 cooperate to collect relevant images of dual-energy X-rays; since the distance between the visible light imaging system and the X-ray imaging system is fixed, the distance difference between them can be obtained, and the difference in the image space can be calculated.

[0027] Moreover, the X-ray emitter 302 and the line scan camera 403 are installed in parallel above the coal gangue separator and are encapsulated with X-ray blocking materials to reduce the interference of X-ray imaging on visible light imaging.

[0028] Embodiment 2: Refer to Figures 1 - 9 , a coal gangue separation equipment based on the fusion of a visible light camera and X-rays, including a bracket 1. A conveyor belt 202 is arranged on the bracket 1. It also includes a support leg 3 fixedly arranged on the bracket 1. A top plate 301 is arranged on the support leg 3. An X-ray emitter 302 is arranged on the top plate 301. A detector 304 is also arranged between the surrounding conveyor belts 202, and the detector 304 is fixedly connected to the bracket 1; a vertical plate 305 is fixedly connected to the top plate 301, and a line scan camera 403 is fixedly connected to the vertical plate 305; a U-shaped frame 4 is fixedly arranged on the bracket 1, and a strip light source generator 402 cooperating with the line scan camera 403 is slidably arranged on the U-shaped frame 4.

[0029] Refer to Figures 1 - 5 , there are two U-shaped frames 4, and the two U-shaped frames 4 are respectively fixedly arranged on both sides of the bracket 1. A chute 401 is arranged on the U-shaped frame 4. T-shaped blocks 404 are rotatably connected to both sides of the strip light source generator 402, and the T-shaped blocks 404 are slidably connected in the chute 401.

[0030] Refer to Figures 1 - 7 , a partition plate 5 is fixedly connected to the outer wall of the U-shaped frame 4. A threaded rod 501 is rotatably connected to the partition plate 5, and the T-shaped block 404 is threadedly connected to the threaded rod 501.

[0031] Reference Figures 1 - 7 A limiting rod 502 is fixedly connected to the partition 5, the T-block 404 is slidably connected to the limiting rod 502, and a second turning handle 509 is provided at the bottom of the threaded rod 501.

[0032] In this embodiment, when in use, firstly, the threaded rod 501 is rotated so that the threaded rod 501 is threadedly connected with the T-block 404 while rotating, and under the action of the limit rod 502 and the slide groove 401, the T-block 404 can be guided, and at the same time, the T-block 404 can be prevented from rotating with the threaded rod 501. Therefore, under the rotation of the threaded rod 501, the T-block 404 can be driven to move, so that the T-block 404 drives the strip light source generator 402 to move, and then the height of the strip light source generator 402 is adjusted, which is convenient for use. Secondly, the T-block 404 is connected to the strip light source generator 402 for rotation. Therefore, in the subsequent work of driving the strip light source generator 402 itself to rotate, the T-block 404 will not interfere.

[0033] Reference Figures 1 - 7 A connecting shaft 405 is fixedly connected to both sides of the strip light source generator 402, a ratchet 407 is provided on the outer wall of the connecting shaft 405, an annular plate 503 is fixedly connected to the T-block 404, and a ratchet 506 meshing with the ratchet 407 is rotatably connected inside the annular plate 503.

[0034] In the present embodiment, after the height adjustment of the strip light source generator 402 is completed, the rotation adjustment of the strip light source generator 402 can also be achieved. Specifically, rotating the knob 406 can drive the connecting shaft 405 to rotate, and then drive the ratchet 407 to rotate through the connecting shaft 405. When the ratchet 407 rotates, it will drive the pawl 506 to rotate. When the strip light source generator 402 moves to a suitable angle and no longer rotates, the pawl 506 will automatically insert into the ratchet 407 under the action of the torsion spring 507, thereby fixing the ratchet 407 so that the ratchet 407 will not reverse. Therefore, the connecting shaft 405 and the strip light source generator 402 will not reverse, which is convenient for use, thereby achieving the angle adjustment of the strip light source generator 402.

[0035] Reference Figures 1 - 7 A support plate 504 is fixedly connected inside the annular plate 503 , a rotating shaft 505 is rotatably connected to the support plate 504 , a ratchet 506 is fixedly arranged on the rotating shaft 505 , and a first turning handle 508 is arranged on the rotating shaft 505 .

[0036] Reference Figures 1 - 7, a torsion spring 507 is provided between the pawl 506 and the outer wall of the support plate 504. The torsion spring 507 is sleeved on the outer wall of the rotating shaft 505. A plurality of pawls 506 are circumferentially distributed. One end of the connecting shaft 405 away from the strip light source generator 402 is provided with a knob 406.

[0037] When it is necessary to reset the strip light source generator 402, there are two methods. One is to use the above-mentioned forward rotation operation to make it rotate one week and return to the initial position. The other method is to reverse the connecting shaft 405 to drive the strip light source generator 402 to reverse to the initial position. During the reverse operation, first rotate the first turning handle 508 to separate the meshing connection between the pawl 506 and the ratchet wheel 407. At this time, the connecting shaft 405 can be driven to reverse through the knob 406, so that the strip light source generator 402 reverses. After the reverse rotation is completed, release the first turning handle 508. Under the action of the torsion spring 507, the pawl 506 will mesh with the ratchet wheel 407 again to fix the ratchet wheel 407. At this time, the next operation can be carried out.

[0038] Embodiment Three: Refer to Figures 1 - 9 , a coal gangue sorting device based on the fusion of a visible light camera and X-rays, including a bracket 1. A conveyor belt 202 is arranged on the bracket 1. It also includes a support leg 3 fixedly arranged on the bracket 1. A top plate 301 is arranged on the support leg 3. An X-ray emitter 302 is arranged on the top plate 301. A detector 304 is also arranged between the circumferentially arranged conveyor belts 202, and the detector 304 is fixedly connected to the bracket 1; a vertical plate 305 is fixedly connected to the top plate 301, and a line scan camera 403 is fixedly connected to the vertical plate 305; a U-shaped frame 4 is fixedly arranged on the bracket 1, and a strip light source generator 402 cooperating with the line scan camera 403 is slidably arranged on the U-shaped frame 4.

[0039] Refer to Figures 3 - 7 , there are two inclined strip light source generators 402, and the inclination angle between the two strip light source generators 402 is 50 - 80 degrees. The line scan camera 403 is arranged above the two strip light source generators 402; it can make the converging light paths emitted by the two strip light source generators 402 fuse on the best imaging surface of the line scan camera 403.

[0040] Refer to Figures 1 - 2 , a driving part 101 is arranged on the bracket 1. The output end of the driving part 101 is provided with a driving gear 102. A driven shaft 201 is rotatably connected to the bracket 1. A rotating roller 2 is fixedly connected to the driven shaft 201. The conveyor belt 202 is sleeved on the rotating roller 2. A driven gear 203 is arranged on the driven shaft 201. An auxiliary gear 103 is also rotatably connected to the bracket 1. The auxiliary gear 103 meshes with the driving gear 102 and the driven gear 203.

[0041] In the present invention, when starting to work, the driving unit 101 is started, so as to drive the driving gear 102 at its output end to rotate, and then drive the auxiliary gear 103 meshing therewith to rotate, and further drive the driven gear 203 meshing with the auxiliary gear 103 to rotate, so that the driven shaft 201 connected to the driven gear 203 can rotate, and then the conveyor belt 202 can be driven to start working by the rotating roller 2.

[0042] In this application, with reference to Figure 10 , an algorithm process is also proposed. After the visible light imaging unit and the X-ray imaging unit on the conveyor belt 202 collect images, two image queues are obtained on the computer via the vision acquisition card and difference compensation is performed. For the offset difference between the two, after such processing, the difference in the image acquisition order caused by the front-back position difference of the visible light imaging system and the X-ray imaging system installed on the main conveyor belt is eliminated. On this basis, subsequent image processing is performed to fuse the images of the visible light image imaging system and the dual-energy X-ray imaging system, and the coal gangue categories in the image are comprehensively interpreted; the specific operation is as follows: after the visible light imaging unit and the X-ray imaging unit collect images, X-ray target detection and classification, and visible light target detection and classification are respectively performed, and then X-ray image processing and visible light image processing are performed, and the detection results of the two are fused and processed, and the final detection result is sent to the motion control mechanism.

[0043] As described above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
