Description

Technical Field

[0001] The present invention relates to the technical field of ore transportation, in particular to an ore transportation device for mining. Background Art

[0002] Belt conveyors are widely used to efficiently transport ore during mining operations. Their continuous and efficient conveying capabilities have made them indispensable equipment in mining, smelting, and processing. Mining belt conveyors typically utilize an endless rubber belt with a steel cord, powered by a drive drum and supported by rollers to form a trough structure, enabling continuous and stable conveyance of ore.

[0003] For example, the patent publication number CN221252622U discloses an ore conveying device for mining, including: a conveyor, a movable component and a side plate, the movable component is installed on both sides of the conveyor, the movable component is composed of a connecting plate, a base plate, a connecting piece, a cylinder and a fixed block, the connecting plate is fixedly installed on the frame on both sides of the conveyor, the base plate is fixedly installed on the top of the connecting plate, and the cylinder is fixedly installed on the base plate through a connecting piece, the telescopic direction of the cylinder is perpendicular to the conveying direction of the conveyor belt of the conveyor, the telescopic rod of the cylinder is fixedly connected to the fixed block, the side plates are arranged on both sides of the conveyor belt of the conveyor, and the side plates are fixedly connected to the fixed block, and a row of ball grooves are provided at the bottom of the side plate, universal balls are installed in the ball grooves, and the universal balls can roll in the ball grooves.

[0004] Although the above device solves the problem of conveyor belt wear, it still has the following defects: during the belt conveying process, the conveyor belt is prone to wear due to long-term operation and friction. In order to detect wear in a timely manner and prevent the conveyor belt from breaking, a thickness detection sensor is usually installed on the conveyor belt frame to monitor the thickness changes of the belt in real time. However, in actual use, ore impurities or raw material particles often adhere to the surface of the conveyor belt. At the same time, some materials themselves contain a certain amount of moisture and are easily attached to the belt surface. These factors will affect the sensor's accurate measurement of the belt thickness, resulting in deviations in the detection results, thereby affecting the judgment of the wear status of the conveyor belt, and posing certain safety hazards.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] See also Figures 1-10 A mining ore conveying device includes a conveyor body 1, a conveyor belt 2 connected to the conveyor body 1, a frame 3 connected to the conveyor body 1, and a plurality of thickness detectors 4 connected between the vertical frames on both sides of the frame 3. The inner walls of the vertical frames on both sides of the frame 3 are fixedly connected to two brackets 8, and the plurality of thickness detectors 4 are connected to the brackets 8. The top of the bracket 8 is connected to a bottom plate 11, and the top surface of the bottom plate 11 is fixedly connected to two connecting frames 10. A water pipe 5 is connected between the connecting frames 10, and the outer wall of the water pipe 5 is fixedly connected to the bottom plate 11. There are multiple first nozzles 9 connected to the inside of the water pipe 5, and the multiple first nozzles 9 are all located below the conveyor belt 2. The outside of the water pipe 5 is connected to a high-pressure flushing device through a water inlet pipe. The top of the bottom plate 11 is also fixedly connected to a drying module, which includes an air knife 16. The air knife 16 is connected to multiple second nozzles 20. The multiple second nozzles 20 are all located below the conveyor belt 2. The bottom of both ends of the air knife 16 is fixedly connected to an L-shaped frame 18 fixed to the bottom plate 11, and the air knife 16 is connected to an air compressed blowing device through an air inlet pipe.

[0033] The ore conveying device for mining in the present invention can start the external high-pressure water flushing equipment and compressed air blowing equipment when the thickness of the conveyor belt 2 needs to be detected, so that water enters the water pipe 5 and is sprayed out through the first nozzle 9, so that multiple first nozzles 9 are directed to flush the conveying surface that has been turned over and has no material, and clean the impurities attached to the conveying surface of the conveyor belt 2, so that the surface to be detected of the conveyor belt 2 is free of impurities. Then, as the conveyor belt 2 continues to move, when it passes through the air-drying module, the external compressed air blowing equipment is activated to allow the wind knife 16 to enter air, and multiple second nozzles 20 are aimed at the cleaned conveying surface for air-drying. Moreover, as the conveyor belt 2 continues to move, at this time, the surface to be detected is already dry and can be detected by the thickness detector 4, thereby ensuring the accuracy of the wear detection of the conveyor belt 2.

[0034] It should be noted that the high-pressure flushing equipment can be a high-pressure flushing machine composed of a high-pressure plunger pump and an electric motor, etc., to ensure that the sprayed high-pressure water source has sufficient pressure to flush out impurities adhered to the conveying surface of the conveyor belt 2. The air-compressed blowing equipment can be an air compressor to ensure effective drying of the conveyor belt 2.

[0035] By setting up the water pipe 5 and the first nozzle 9, impurities adhering to the conveying surface of the conveyor belt 2 to be inspected can be washed away to ensure the accuracy of the surface to be inspected during inspection; the conveying surface after washing is air-dried by using the air knife 16 and the second nozzle 20 to further improve the inspection accuracy.

[0036] As a preferred technical solution of the present invention, a cleaning structure is connected between the water pipe 5 and the wind knife 16. The cleaning structure includes a brush plate 13 and a brush 14. The brush plate 13 is connected to the connecting frame 10 by bolts. The top of the brush plate 13 is connected to the brush 14. The bristles of the brush 14 are against the conveying surface of the conveyor belt 2.

[0037] Specifically, after the surface to be inspected of the conveyor belt 2 is flushed, the conveyor belt continues to move. At this time, the surface to be inspected will pass through the cleaning structure, and the brush 14 will brush the cleaned surface to be inspected to ensure that the remaining stubborn impurities are brushed off again, thereby ensuring that the cleanliness of the surface to be inspected is improved again, thereby improving the accuracy of the detection data.

[0038] As a preferred technical solution of the present invention, a T-shaped slot 23 is provided on the outer wall of the brush plate 13, and a T-shaped plate 17 fixed to the bottom of the brush 14 is inserted into the T-shaped slot 23. The outer wall of the T-shaped plate 17 is connected to the brush plate 13 by fastening bolts.

[0039] Specifically, in order to ensure that the brush 14 can be easily replaced after being used for a period of time, the T-shaped plate 17 at the lower end of the brush 14 is separated from the T-shaped slot 23 on the brush plate 13 to replace the brush 14. During installation, it is only necessary to clamp the T-shaped plate 17 at the lower end of the brush 14 with the T-shaped slot 23 on the brush plate 13, and then reinforce the fastening bolts to ensure the stability of the brush 14 on the brush plate 13.

[0040] As a preferred technical solution of the present invention, a scraping structure is also connected between the brush 14 and the wind knife 16, and the scraping structure includes a scraper 15. The bottoms of both ends of the scraper 15 are connected to L-shaped columns 21, and the L-shaped columns 21 are fixedly connected to the outer wall of the brush plate 13.

[0041] Specifically, after the conveyor belt 2 to be inspected is brushed by the brush 14 after being rinsed, it will pass through the scraper 15. The scraper 15 can be used to peel off the stubborn impurities remaining on the moving conveyor belt 2 on the one hand, and to scrape off the water stains on the other hand, thereby ensuring that the subsequent air knife 16 and the second nozzle 20 have improved drying efficiency and the drying effect.

[0042] Furthermore, the scraper 15, brush 14, and brush plate 13 not only remove stubborn impurities remaining on the conveyor belt surface, assisting in cleaning, but also provide a shielding and protective function. Specifically, the scraper 15, brush 14, and brush plate 13 effectively block splashing caused by the mixing of flushing water and impurities sprayed from the first nozzle 9, preventing dirty water from adhering to the detection end of the thickness detector 4. This prevents a decrease in detection sensitivity due to contamination and ensures the accuracy and stability of the detection results.

[0043] As a preferred technical solution of the present invention, a slide groove 12 is opened inside the vertical column of the L-shaped column 21, and the bottom of the scraper 15 is fixedly connected to a slide column 22 that is slidably connected to the slide groove 12. The bottom surface of one end of the slide column 22 located in the slide groove 12 is fixedly connected to the first spring 19, and the bottom surface of the first spring 19 is fixedly connected to the bottom surface of the slide groove 12.

[0044] Specifically, in order to ensure that the scraper 15 has a good stripping effect on the residual impurities on the conveying surface of the conveyor belt 2, when the scraper 15 is in use, the sliding column 22 at the bottom of the scraper 15 will slide in the slide groove 12 in the L-shaped column 21. Under the elastic potential energy of the first spring 19, the sliding column 22 can always be pushed upward, ensuring that the scraper 15 can always scrape against the conveying surface of the conveyor belt 2, so that the effect of stripping stubborn impurities is better.

[0045] As a preferred technical solution of the present invention, a marking structure is also connected between the two brackets 8. The marking structure is located on the outside of the thickness detector 4 away from the wind knife 16. The marking structure includes a fixed box 6. A plurality of lifting probes 27 are slidably connected in the fixed box 6. The top of each lifting probe 27 passes through the fixed box 6 and is against the conveying surface of the conveyor belt 2. One end of the lifting probe 27 located in the fixed box 6 is fixedly connected to a second spring 36. The second spring 36 is fixedly connected to the bottom surface of the fixed box 6. The outer wall of each lifting probe 27 is fixedly connected to a rack plate 28. The outer side of the rack plate 28 is meshed with a gear 29. The axis of the gear 29 is fixedly connected to the center shaft 33. The outer side of one end of the center shaft 33 is rotatably connected to a fixed frame 35. The top surfaces of the two brackets 8 are connected to a paint spraying structure.

[0046] Specifically, after the thickness detector 4 detects, it is impossible to mark the wear at the corresponding position. Therefore, when the conveyor belt 2 continues to move, the lifting probe 27 is subjected to the elastic potential energy of the second spring 36 in the fixed box 6, so that the top of the lifting probe 27 always contacts the cleaned surface of the conveyor belt 2. When the belt passes, the probe is displaced according to the depth of surface wear, that is, the deeper the wear, the greater the rise of the probe. When the lifting probe 27 moves up, the lifting probe 27 drives the rack plate 28 to rise, and the rack plate 28 engages with the gear 29, and the gear 29 drives the center shaft 33 to rotate in the fixed frame 35. When rotating, the paint spraying structure can be triggered to spray mark the worn position on the conveyor belt 2. When the workers make subsequent repairs, the marked position is clearly the worn position, and it is convenient for the workers to perform different repair methods according to different color markings.

[0047] As a preferred technical solution of the present invention, the paint spraying structure includes two paint boxes 7, and the top surfaces of the two paint boxes 7 are connected to multiple third nozzles 26. The number of third nozzles 26 on the top of each paint box 7 corresponds to the number of lifting probes 27. Each third nozzle 26 is connected to a solenoid valve 31 for opening and closing the third nozzle 26. The outer wall of the paint box 7 is connected to an external spraying equipment through a feed pipe, and the outer side of the central axis 33 is connected to a trigger structure for opening and closing the solenoid valve 31.

[0048] As a preferred technical solution of the present invention, the trigger structure includes a trigger piece 30, an extension plate 34 and a trigger plate 24. The central axis 33 is fixedly connected to the extension plate 34 at one end away from the fixed frame 35, and the fixed frame 35 is fixedly connected to an arc plate 32 on one side. The outer wall of the arc plate 32 is fixedly connected to two L-shaped trigger plates 24. The trigger plate 24 and the extension plate 34 are connected to the opposite surfaces of the trigger plate 24. The trigger pieces 30 located on the trigger plate 24 are electrically connected to the corresponding solenoid valves 31 through cables.

[0049] Specifically, when the gear 29 rotates, it drives the central shaft 33 to rotate in the fixed frame 35. The rotation of the central shaft 33 drives the extension plate 34 to rotate. The extension plate 34 drives the trigger piece 30 on its inner wall, and the trigger piece 30 on the trigger plate 24 contacts. Since the trigger plate 24 is fixed on the curved plate 32, and the curved plate 32 is fixed to the fixed frame 35, when the gear 29 rotates, the curved plate 32 does not move, the trigger plate 24 remains stationary, and the trigger piece 30 on the extension plate 34 will contact the trigger pieces 30 on the two trigger plates 24.

[0050] When the degree of wear reaches a certain threshold, the lifting probe 27 rises to a certain distance. Under the engagement of the rack plate 28 and the gear 29, the extension plate 34 rotates, so that the trigger plate 30 on the extension plate 34 contacts the trigger plate 30 on the first trigger plate 24. At this time, the two trigger plates 30 are powered on, opening the solenoid valve 31 on the corresponding third nozzle 26. After the solenoid valve 31 is opened, the corresponding third nozzle 26 is opened, so that the external spraying equipment sprays the paint, and a mark appears at the corresponding position.

[0051] When the degree of wear is greater, the lifting probe 27 continues to rise, and the gear 29 rotates at a greater angle. At this time, the extension plate 34 rotates at a greater angle. The extension plate 34 continues to rotate and will disengage from the first trigger plate 24 and contact the trigger plate 30 on the second extension plate 34. At this time, the solenoid valve 31 connected to the trigger plate 30 will open, causing another set of color pigments to be sprayed out; the colors of the two sets of pigments can be yellow and red, respectively indicating different degrees of wear. The color sprayed by the third nozzle 26 that is opened first is yellow, and the color sprayed by the third nozzle 26 that is opened later should be red. The pigment is non-corrosive and degradable to prevent corrosion to the conveyor belt 2.

[0052] Since the two paint boxes 7 are provided with a plurality of third nozzles 26 corresponding to the lifting probes 27, the different degrees of wear at different positions on the conveying surface of the conveyor belt 2 can be reflected. The above structure can facilitate the detection of different degrees of wear of the conveyor belt 2 when it needs maintenance, making subsequent repairs more convenient.

[0053] In addition, due to the different degrees of wear at different positions of the belt, the lifting probe 27 will be repeatedly raised and lowered. Based on this, the trigger piece 30 on the extension plate 34 will repeatedly contact and separate from the trigger pieces 30 on the two trigger plates 24. There is a possibility that the paint sprayed under the two wear conditions will be covered. This can also clearly identify the different degrees of wear at different positions.

[0054] As a preferred technical solution of the present invention, the outer wall of the fixed box 6 is fixedly connected to the U-shaped cover 25, and multiple fixing frames 35 are fixedly installed on the bottom surface of the inner wall of the U-shaped cover 25. The cable of the trigger piece 30 located on the trigger plate 24 passes through the U-shaped cover 25 and is electrically connected to the solenoid valve 31.

[0055] Specifically, the provision of the U-shaped cover 25 can facilitate protection of the plurality of lifting probes 27 , the rack plate 28 and the gear 29 , thereby reducing the probability of the rack plate 28 and the gear 29 being contaminated.

[0056] As a preferred technical solution of the present invention, the top surface of the U-shaped cover 25 is slidably connected to a U-shaped abutment plate 37 , and the bottom surface of the U-shaped abutment plate 37 abuts against the top surfaces of the plurality of lifting probes 27 .

[0057] Specifically, when the lifting probes 27 are not in use, in order to prevent the lifting probes 27 from being constantly in contact with the conveyor belt 2 and being worn, the U-shaped retaining plate 37 can be slid so that the U-shaped retaining plate 37 moves horizontally on the top surface of the U-shaped cover 25, and the transverse plate of the U-shaped retaining plate 37 slides out to abut against the top surfaces of the multiple lifting probes 27. In this way, the lifting probes 27 are pressed down to prevent damage to the tops of the lifting probes 27. The U-shaped retaining plate 37 is pressed upward by the lifting probes 27 and will not retreat, thereby ensuring that the U-shaped retaining plate 37 always limits the multiple lifting probes 27.

[0058] In the above structure, the corresponding structure is used to complete the flushing, cleaning, air drying, testing and marking of the conveyor belt 2, which not only effectively ensures the accuracy of the conventional thickness detector 4 during detection, but also can make different marks on different positions and different degrees of wear depth on the clean conveying surface, making it convenient to carry out different repair work for different marks in the future.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
