Description

Technical Field

[0001] The invention relates to the field of dust removal and dust prevention, and in particular to a dust reduction component at the rear of a mining trackless rubber-wheeled vehicle. Background Art

[0002] The mining trackless rubber-tyred vehicle is a kind of transport vehicle specially used in mines, coal mines and other construction sites. Its main feature is that it does not require tracks and is easy and quick to use. The mining trackless rubber-tyred vehicle uses rubber wheels as tires. Compared with metal tires, it has the advantages of light weight, low friction, wear resistance, and no damage to the ground. It is particularly suitable for harsh field working environments.

[0003] In the patent with publication number CN221138013U, a dust reduction carriage of an explosion-proof diesel engine trackless rubber-tyred vehicle is disclosed, including: a carriage group for staff to sit on, and a moving wheel installed on the outside of the carriage group for supporting the movement of the carriage group.

[0004] However, the above-mentioned dust reduction compartment still has certain defects when in use. The above-mentioned dust reduction compartment can only reduce dust in the environment, but during the operation of the rubber-tyred trackless vehicle, the rubber-tyred trackless vehicle will stir up dust from the ground, and as the mass it carries increases, the dust stirred up will be more. Secondly, the wheels of the rubber-tyred trackless vehicle are usually provided with bearings, and the bearings are usually filled with lubricating oil. The temperature of the bearings will rise with the operation of the rubber-tyred trackless vehicle, and as the mass it carries increases, the temperature of the bearings will be higher. Excessive temperature of the bearings will cause the temperature of the lubricating oil inside them to rise, and after the temperature of the lubricating oil rises, the viscosity will decrease, reducing the lubrication efficiency, thereby aggravating the wear of the bearings.

The two vertical ends of the built-in tube 13 extend to the inside of the mounting plate 8. A transverse hole 24 is provided at the inner bottom of the mounting plate 8.

[0048] In a specific implementation, the electromagnetic three-way valve 17 is provided to effectively reduce dust on the ground when the device is loaded with ore, and to facilitate flushing of the filter screen 21 .

[0051] As a further embodiment of the present invention, mudguards 33 are provided on both sides above the wheel hub 3 , the mudguards 33 are fixedly connected to the bottom wall plate of the bottom plate 2 , and the rectangular box body 5 is located on one side of the mudguard 33 .

[0052] In a specific implementation, by arranging the rectangular box body 5 on one side of the fender 33, the fender 33 can shield the dust to a certain extent during the driving of the device, and the rectangular box body 5 can further reduce the dust. Figure 2 As shown, the rectangular box body 5 is arranged on a side of the fender 33 away from the forward direction of the automobile.

[0053] Working principle of the present invention:

[0054] When the present invention is used, first, a sufficient amount of water is added to the water tank 7, and then the device is driven to a place where it needs to be transported. During the operation, the fan 20 is turned on. After the fan 20 is turned on, air is drawn from the dust box 9 through the rectangular air pipe 32. As the fan 20 runs, the airflow forms a negative air pressure in the dust box 9, and then air is drawn from the four rectangular boxes 5. During the operation of the device, the wheel hub 3 will contact the ground of the mine, and then the dust on the ground of the mine will be stirred up. The airflow in the rectangular box 5 can effectively 3 effectively absorbs the dust stirred up on the ground, thereby achieving the purpose of reducing dust. On the one hand, it can effectively reduce dust. On the other hand, by reducing dust, it can also reduce the probability of dust falling on the bearing 4. By reducing the probability of dust falling on the bearing 4, the bearing 4 can be effectively cooled, which is conducive to avoiding the excessive temperature of the lubricating oil in the bearing 4 caused by the dust covering the outside of the bearing 4, thereby reducing the viscosity of the lubricating oil, resulting in insufficient lubrication of the lubricating oil to the bearing 4, thereby causing the bearing 4 to wear more severely and reducing the service life of the bearing 4.

[0055] When a mine is opened in a mountainous area, it is difficult to travel on mountain roads. By adding a water tank 7 at the bottom of the device, the center of gravity of the device can be effectively lowered, thereby improving the stability of the device during the unloaded process, which is beneficial to reducing the probability of the device rolling over when traveling on mountain roads.

[0056] After the gas enters the fan 20, the airflow will be transported to the built-in tube 13 through the output end of the fan 20, and then transported to the exhaust box 27 through the transverse holes 24 at both ends of the built-in tube 13. The rectangular air holes 28 opened at the top and bottom of the exhaust box 27 are used. The rectangular air holes 28 located at the top will transport the gas to the rubber wheel outside the hub 3, which is conducive to cooling the rubber wheel, thereby avoiding stress fatigue of the rubber wheel due to excessive temperature, and effectively improving the service life of the rubber wheel. The rectangular air holes 28 located at the bottom can guide part of the airflow to the outer ring of the bearing 4. On the one hand, it can cool the bearing 4 and maintain the viscosity of the lubricating oil inside the bearing 4. On the other hand, it can also blow off the dust on the bearing 4, which is conducive to avoiding the situation where the heat dissipation efficiency of the bearing 4 is reduced due to excessive dust covering the bearing 4. By ensuring the heat dissipation of the bearing 4, the viscosity of the lubricating oil inside the bearing 4 is further guaranteed, so as to ensure the lubrication of the bearing 4 and reduce the wear of the bearing 4.

[0057] After the device travels to the loading area, the mass of the vehicle body 1 is increased by placing the ore on the vehicle body 1. After the mass of the vehicle body 1 is increased, the wear of the bearing 4 is increased, and the friction between the rubber wheel and the ground is also increased, so that the rubber wheel stirs up more dust from the ground. Therefore, after loading the ore, by turning on the water pump 16, on the one hand, the water in the water tank 7 can be discharged to reduce the carrying capacity of the vehicle body 1, and on the other hand, the water in the water pump 16 can be used for further dust reduction.

[0058] After the device is loaded with ore, during the driving process of the device, the output end of the water pump 16 is connected to the second water pipe 19 by controlling the electromagnetic three-way valve 17, so that after the water pump 16 is turned on, the water in the water tank 7 is transported to the second water pipe 19. After entering the second water pipe 19, the water flows into the external water pipe 15, and then enters the transverse water pipe 29 through the two ends of the external water pipe 15. After entering the transverse water pipe 29, the water flows through the atomizing nozzles located on both sides of the mounting plate 8 and sprayed on the wheel. On the hub 3 and the bearing 4, on the one hand, the dust stirred up by the rubber wheel from the ground can be further reduced by sprinkling water, and on the other hand, the bearing 4 can be effectively cooled by sprinkling water. Secondly, the airflow flowing out of the rectangular air hole 28 can also accelerate the evaporation of the water mist sprayed by the atomizing nozzle. By utilizing the heat absorption characteristic of water evaporation, the temperature of the bearing 4 and the rubber wheel can be further reduced, and the viscosity of the lubricating oil in the bearing 4 can be further increased. At the same time, it can also help to avoid the rubber wheel from being damaged due to excessive temperature.

[0059] During the driving of the device, the outer ring of the bearing 4 will rotate with the rotation of the wheel hub 3. During the rotation, the outer ring of the bearing 4 will come into contact with the scraper 25. The scraper 25 can be used to effectively scrape the exposed part of the bearing 4. On the one hand, it can scrape off the dust on the exposed part of the bearing 4, thereby improving the heat dissipation path of the bearing 4. On the other hand, it can be combined with the water mist sprayed by the atomizing nozzle to achieve the effect of cleaning the exposed part of the bearing 4.

[0060] By setting the atomizing nozzle, on the one hand, the temperature of the bearing 4 and the rubber wheel can be reduced, and the service life of the bearing 4 and the rubber wheel can be increased. On the other hand, the exposed part of the bearing 4 can be effectively flushed. Secondly, the water mist sprayed by the atomizing nozzle can also play a role in dust reduction. When the mass of the device increases, the amount of dust stirred up by the device from the ground can be effectively reduced, which is conducive to avoiding the situation where the device has safety hazards during driving due to excessive dust affecting the line of sight. After the device is driven to the destination, the ore carried on the vehicle body 1 is unloaded, and then the ore can be unloaded.

[0061] During the vacuuming process of the rectangular box body 5, the dust will enter the connecting pipe 6 through the rectangular box body 5, then enter the transverse pipe 11 through the connecting pipe 6, and finally enter the rectangular connecting pipe 23 through the transverse pipe 11. After entering the rectangular connecting pipe 23, the dust will enter the dust collecting box 9, and then under the cover of the filter 21, the dust will fall on the sealing plate 12, and the airflow will enter the fan 20 through the rectangular air pipe 32. When the device is traveling on a mountain road or a mine, the road surface will be relatively bumpy. The bumpy road surface is used to shake the dust on the filter 21 onto the sealing plate 12, which is conducive to maintaining the filtering efficiency of the filter 21 and avoiding the situation where the filter 21 is blocked by dust.

[0062] When the dust accumulates to a certain extent, the sealing plate 12 is opened. After the sealing plate 12 is opened, the dust in the dust box 9 will fall to the ground, and the output end of the water pump 16 is connected to the first water pipe 18 by controlling the electromagnetic three-way valve 17. Then the water pump 16 is turned on. After the water pump 16 is turned on, the water in the water tank 7 will be transported to the first water pipe 18, and then the water will be transported to the rectangular groove 22 through the first water pipe 18, and finally enter the dust box 9 through the flushing hole 31, so as to realize the effective cleaning of the filter screen 21 and avoid the filter screen 21 being blocked due to excessive dust.

[0063] Secondly, the water pump 16 can be turned on without opening the sealing plate 12, and the water flow can be used to spray water on the dust at the bottom of the dust box 9, and then the sealing plate 12 can be opened. This is helpful to avoid excessive dust from the sealing plate 12. After opening the sealing plate 12, the filter screen 21 can still be flushed.

[0064] By setting the rectangular connecting tube 23, the filter 21 and the rectangular air duct 32, the dust will be preferentially concentrated at the center of the filter 21. When the center of the filter 21 is blocked by dust, the airflow will enter the rectangular air duct 32 through the center and edge area of ​​the filter 21. By setting the area of ​​the filter 21 to be larger than the cross-sectional area of ​​the rectangular connecting tube 23, the probability of the filter 21 being blocked can be effectively increased, thereby avoiding the idling of the fan 20. By avoiding the idling of the fan 20, the service life of the fan 20 is guaranteed, and the fan 20 is prevented from being damaged due to overheating.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
