[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Please see Figure 1-3This utility model provides a dust detection device for conveying bulk ore, including a mounting frame 1. A dust detection pipe 3 is connected to the top of the mounting frame 1. A fan 4 is installed at one end of the dust detection pipe 3, and a large particle filter plate 18 is fixedly connected to the other end of the dust detection pipe 3. A second rotating shaft 17 is rotatably connected to the outer surface of the large particle filter plate 18 via a bearing. A scraper 19 is fixedly sleeved at the bottom end of the second rotating shaft 17. A mounting box 6 is fixedly connected to the top of the mounting frame 1. A servo motor 7 is fixedly connected to the top of the mounting box 6. A first rotating shaft 13 is fixedly connected to the output shaft of the servo motor 7, and another first rotating shaft 13 is rotatably connected to the top of the inner cavity of the mounting box 6. The two first rotating shafts 1... Gears 14 are fixedly fitted onto the outer surface of the dust detection tube 3, and two gears 14 mesh with each other. Synchronous pulleys 15 are fixedly fitted onto the bottom ends of the first rotating shaft 13 and the second rotating shaft 17. A synchronous belt 16 is connected between the two synchronous pulleys 15 through tooth grooves. A servo motor 7 is fixedly connected to the top of each synchronous pulley 15, and a pin 9 is fixedly connected to the top of the servo motor 7. A sliding port block 11 is connected to the bottom of the dust detection tube 3. A square opening is formed on the outer surface of the sliding port block 11, and insertion interfaces 12 are formed on both sides of the square opening. A insertion plate 20 is slidably inserted between the two insertion interfaces 12, and a dust detection sensor device is fixedly inserted onto the outer surface of the insertion plate 20. One end of the dust detection sensor device 21 is fixed to the top of the mounting frame 1, and the bottom of the plug plate 20 is fixed to the connecting plate 10, and the bottom of the connecting plate 10 is fixed to the connecting block 8. The bottom of the connecting block 8 is provided with a sliding groove, and the plug post 9 is slidably inserted into the inside of the sliding groove. The top side of the sliding block 11 is fixed to the cleaning box 22, and the inside of the cleaning box 22 is equipped with multiple cleaning brushes 23. When the mounting frame 1 is installed in the path of the bulk ore conveying, the dust inside the mounting frame 1 is drawn into the dust detection tube 3 by turning on the fan 4. At the same time, the servo motor 7 is turned on, and the two synchronous pulleys 15 are rotated by the meshing of the two gears 14, which drives the scraper. Plate 19 rotates and scrapes at the bottom of the large particle filter plate 18, thus preventing large particles from adsorbing and hindering filtration when the large particle filter plate 18 filters large particles, and preventing large dust particles from affecting the accuracy of dust concentration detection. On another front, a first rotating shaft 13 drives the servo motor 7 to rotate, causing the insertion post 9 to slide back and forth inside the groove of the connecting block 8. This causes the probe head of the dust detection sensor device 21 to slowly move back and forth inside the dust detection tube 3. Meanwhile, the insertion plate 20 slides inside the two insertion interfaces 12, increasing the sealing at the bottom of the dust detection tube 3. During the reciprocating sliding detection process of the probe head of the dust detection sensor device 21, it can also slide inside the cleaning box 22.Thus, the cleaning brush 23 continuously cleans the probe of the dust detection sensor device 21, thereby preventing the dust detection efficiency from being affected by dust coverage and thus maintaining accuracy.
[0021] To facilitate cleaning and inspection of the cleaning brush 23 and the dust detection sensor device 21, and to ensure the dust detection efficiency of the dust detection sensor device 21 probe, a maintenance cover 5 is installed on the outer surface of the dust detection tube 3, and the maintenance cover 5 is located directly above the cleaning box 22. The length of the slide is greater than the diameter of the servo motor 7.
[0022] Furthermore, in order to facilitate the reciprocating sliding of the dust detection sensor device 21, and to clean the probe of the dust detection sensor device 21 using multiple cleaning bristles 23, the cleaning box 22 has openings on the outer surface and bottom of one side of the dust detection sensor device 21, and the top of the dust detection sensor device 21 is slidably disposed inside the cleaning box 22.
[0023] Furthermore, to protect the rotational safety of the two gears 14, both gears 14 are rotatably disposed inside the mounting box 6, and both synchronous pulleys 15 and one synchronous belt 16 are rotatably connected inside the mounting bracket 1. It should be noted that, in order to improve the connection safety of the two synchronous pulleys 15 and one synchronous belt 16, a chain and sprocket connection can also be used.
[0024] To facilitate the overall installation of the device, mounting plates 2 are fixed to both sides of the mounting bracket 1, and mounting holes are provided on the outer surface of both mounting plates 2.
[0025] In order to facilitate the scraping of large particles from the filter plate and avoid adhesion that would affect the filtration effect of large particles, thereby improving the accuracy of dust detection, the scraper 19 is rotatably disposed at the bottom of the large particle filter plate 18, and the top of the scraper 19 is in contact with the bottom of the large particle filter plate 18.
[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
