[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 2 and Figure 3, the utility model provides an embodiment: an enhanced dust removal device for coal mine safety, including a filter cartridge 1, a hollow square column 3 is fixedly connected to the top of the filter cartridge 1, a motor 4 is fixedly connected to the right side of the hollow square column 3, the output end of the motor 4 passes through the hollow square column 3 and is fixedly connected to a transmission rod 5, the left and right sides of the outer wall of the transmission rod 5 are fixedly connected to a driving bevel gear 6, the left and right sides of the inner bottom end of the hollow square column 3 are rotatably connected to a transmission column 7, the tops of the two transmission columns 7 are fixedly connected to a driven bevel gear 8, the two driven bevel gears 8 are respectively meshed with the corresponding driving bevel gear 6, the bottom ends of the two transmission columns 7 pass through the hollow square column 3 and the filter cartridge 1 in turn and are fixedly connected to a third gear 9, the left and right sides of the inner top of the filter cartridge 1 are rotatably connected to a support rod 10 , the bottom ends of the two support rods 10 are fixedly connected with a half gear 11, and the two half gears 11 are respectively meshed with the corresponding third gear 9. The left sides of the two half gears 11 are fixedly connected with a connecting rod 12, and the left ends of the two connecting rods 12 are fixedly connected with a knocking ball 13. The inner side of the filter cartridge 1 is fixedly connected with two filter screens 14, and the inner right end of the filter cartridge 1 is fixedly connected with a fan 15. The middle part of the bottom end of the filter cartridge 1 is connected with a collecting box 16. The left and right sides of the outer wall of the filter cartridge 1 are fixedly connected with support rings 17, and the bottoms of the two support rings 17 are fixedly connected with support columns 18. The bottom ends of the two support columns 18 are fixedly connected to the same disc 29. A rotating mechanism 2 is provided on the lower side of the disc 29. The rotating mechanism 2 is used to facilitate the rotation of the dust removal direction of the device;

[0033] Specifically, when using the device, after the fan 15 is started, the air in the coal mine will be sucked into the filter cartridge 1 from the left side. The inhaled air will first pass through the filter screen 14, which can filter out coal dust impurities. The filtered air will be discharged from the right side, thus realizing the dust removal operation of the air in the coal mine. In this process, the motor 4 will drive the transmission rod 5 to rotate, and the rotation of the transmission rod 5 will drive the driving bevel gear 6 to rotate. Because the driven bevel gear 8 and the driving bevel gear 6 are meshed with each other, when the driving bevel gear 6 rotates, the driven bevel gear 8 will drive the transmission column 7 to rotate, and the rotation of the transmission column 7 will cause the third gear 9 to rotate as well. The half gear 11 is in meshing state with the third gear 9, so when the third gear 9 rotates, it will drive the half gear 11 to rotate together. After the half gear 11 rotates, it will drive the connecting rod 12 to rotate. The rotation of the connecting rod 12 will drive the knocking ball 13 to knock on the filter 14. The impurities on the filter 14 will fall off under the influence of the vibration generated by the knocking, so that the filter 14 will not be blocked, and the air can pass through the filter 14 smoothly. Moreover, the impurities falling off on the right filter 14 will fall into the collection box 16 under the action of gravity, which facilitates the collection of impurities, improves the working efficiency of the device, and can meet the needs of users.

[0034] Reference Figure 1 、 Figure 4 and Figure 5 The rotating mechanism 2 includes a hollow box 201, which is arranged on the lower side of the disc 29. The top of the hollow box 201 is rotatably connected to a rotating column 202. The top of the rotating column 202 is fixedly connected to the bottom of the disc 29. The middle part of the outer side of the rotating column 202 is fixedly connected to a first gear 203. The front side of the top of the hollow box 201 is rotatably connected to a first rotating rod 204. The top of the first rotating rod 204 is fixedly connected to a second gear 205. The second gear 20 5 is meshed with the first gear 203. The bottom end of the first rotating rod 204 passes through the hollow box 201 and is fixedly connected to the worm gear 206. The middle part of the front side of the hollow box 201 is rotatably connected to the second rotating rod 207. The rear end of the second rotating rod 207 passes through the hollow box 201 and is fixedly connected to the worm 208. The worm 208 is meshed with the worm gear 206. The front end of the second rotating rod 207 is fixedly connected to the turning handle 19. The bottom of the disk 29 is fixedly connected to the retaining ring 20.

[0035] Specifically, when ventilation and dust reduction work needs to be performed at different angles, the handle 19 can be rotated first. After the handle 19 is rotated, the second rotating rod 207 will be driven to rotate. When the second rotating rod 207 rotates, the worm 208 will rotate together. Since the worm wheel 206 and the worm 208 are meshed with each other, when the worm 208 rotates, the worm wheel 206 will be driven accordingly, thereby driving the first rotating rod 204 to rotate. When the first rotating rod 204 rotates, it will drive the second gear 205 to rotate together. Because the first gear 203 and the second gear 205 are meshed with each other, when the second gear 205 rotates, the first gear 203 will rotate along with it. The rotation of the first gear 203 will drive the rotating column 202 to rotate. The rotation of the rotating column 202 will drive the disc 29 to rotate together. When the disc 29 rotates, the equipment placed on the top of it will also be driven to rotate together, thereby meeting the needs of ventilation and dust reduction work at different angles. At this time, ventilation and dust reduction work can be performed at different angles, increasing the practicality of the device.

[0036] Reference Figure 1 and Figure 3 The bottom of the hollow box 201 is fixedly connected with a plurality of fixing plates 21 on all sides. The tops of the plurality of fixing plates 21 are provided with holes 22. The bottom of the collecting box 16 is provided with a bottom cover 23. The bottom rear end of the bottom cover 23 is fixedly connected with a hinge 24. The bottom cover 23 is rotatably connected to the collecting box 16 through the hinge 24. The front end of the lower side of the bottom cover 23 is fixedly connected with a pull ring 25. The middle part of the front side of the filter cartridge 1 is provided with an observation window 26.

[0037] Specifically, the device can be firmly fixed on the ground using screws through the hole 22 opened at the top of the fixing plate 21. The pull ring 25 can be pulled and the bottom cover 23 can be opened. At this time, the coal dust and other impurities accumulated in the collection box 16 can be cleaned, and the filtering situation inside the filter cartridge 1 can be observed through the observation window 26.

[0038] Reference Figure 1 and Figure 2 The left and right sides of the filter cartridge 1 are fixedly connected with a conical port 27. The sizes of the two filter screens 14 match the internal size of the filter cartridge 1. The top of the front left end of the filter cartridge 1 is fixedly connected with a controller 28. The controller 28 is electrically connected to the motor 4 and the fan 15 respectively.

[0039] Specifically, the conical mouth 27 can help the device to perform air intake and exhaust operations, and the size of the filter 14 matches the internal size of the filter cartridge 1 to ensure that the device filters the air passing through the filter cartridge 1 cleanly. The controller 28 can control the operation of the motor 4 and the fan 15 respectively. The model of the motor 4 is MS8012, and the model of the fan 15 is t35 axial flow.

[0040] Working principle: When the device is used, the fan 15 is started to suck air into the filter cartridge 1 from the left side. The sucked air first passes through the filter screen 14 to filter the coal dust impurities and is then discharged from the right side, thereby removing dust from the air in the coal mine. During this process, the motor 4 will drive the transmission rod 5 to rotate, and the rotation of the transmission rod 5 will drive the active bevel gear 6 to rotate. Since the driven bevel gear 8 is engaged with the active bevel gear 6, the driven bevel gear 8 will drive the transmission column 7 to rotate. At this time, the third gear 9 will rotate accordingly. Since the half gear 11 is engaged with the third gear 9, the rotation of the third gear 9 will drive the half gear 11 to rotate together. At this time, the half gear 11 will drive the connecting rod 12 to rotate. The rotation of the connecting rod 12 will drive the knocking ball 13 to knock on the filter screen 14. The impurities on the filter screen 14 will fall off due to the vibration caused by the knocking, and will not block the filter screen 14, allowing air to pass smoothly. The impurities falling off the right filter screen 14 will fall into the collection box 16 under the action of gravity, making it convenient to collect them.

[0041] And when ventilation and dust reduction work is needed at different angles, the handle 19 can be turned first. The rotation of the handle 19 will drive the second rotating rod 207 to rotate. When the second rotating rod 207 rotates, the worm 208 will rotate accordingly. Since the worm gear 206 is engaged with the worm gear 208, the worm gear 206 will drive the first rotating rod 204 to rotate. When the first rotating rod 204 rotates, it will drive the second gear 205 to rotate. Since the first gear 203 is engaged with the second gear 205, the first gear 203 will drive the rotating column 202 to rotate. The rotation of the rotating column 202 will drive the disc 29 to rotate together. When the disc 29 rotates, it will drive the equipment on its top to rotate. At this time, ventilation and dust reduction work can be performed at different angles.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
