Description

Technical Field

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

[0002] During the process of mine exploitation, belt conveyors are widely used for the efficient transportation of ores. With its continuous and efficient conveying characteristics, the belt conveyor has become an indispensable device in the fields of mining, smelting, and processing. The belt conveyor for mines usually adopts a ring-shaped rubber belt (with a steel wire rope core), provides power through a driving roller, and uses idlers to support and form a trough-shaped structure to achieve continuous and stable conveying of ores.

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

[0004] Although the above device solves the problem of conveyor belt wear, there are still the following defects: During the belt conveying process, due to long-term operation and friction, the conveyor belt is prone to wear. In order to detect the wear situation in time and prevent the conveyor belt from breaking, a thickness detection sensor is usually installed on the conveyor belt frame to monitor the thickness change of the belt in real time. However, in the actual use process, ore impurities or raw material particles often adhere to the surface of the conveyor belt, and at the same time, some materials themselves contain a certain amount of moisture and are prone to adhere to the surface of the belt. These factors will affect the accurate measurement of the belt thickness by the sensor, resulting in deviation of the detection result, thus affecting the judgment of the wear state of the conveyor belt and posing a certain safety hazard. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an ore transportation device for mine mining to solve the problems raised in the background art and improve the accuracy of detecting the thickness wear of the belt in the belt conveyor.

Specific embodiments

[0019] 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.

[0020] Please refer to Figures 1-10 , an ore conveying device for mine mining, including 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. Two brackets 8 are fixedly connected to the inner walls of the vertical frames on both sides of the frame 3. 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. Two connecting frames 10 are fixedly connected to the top surface of the bottom plate 11. A water pipe 5 is connected between the connecting frames 10. A plurality of first nozzles 9 communicating with the inside of the water pipe 5 are fixedly connected to the outer wall of the water pipe 5. The plurality of first nozzles 9 are all located below the conveyor belt 2. The outside of the water pipe 5 is externally connected to a high-pressure flushing device through a water inlet pipe. A drying module is also fixedly connected to the top of the bottom plate 11. The drying module includes an air knife 16. A plurality of second nozzles 20 are connected to the air knife 16. The plurality of second nozzles 20 are all located below the conveyor belt 2. The bottoms of both ends of the air knife 16 are fixedly connected to L-shaped frames 18 fixed to the bottom plate 11. The air knife 16 is externally connected to a pneumatic blowing device through an air inlet pipe.

[0021] In the ore conveying device for mine mining in the present invention, when the thickness of the conveying belt 2 needs to be detected, an externally connected high-pressure water flushing device and an air blowing device can be started, so that water enters the inside of the water pipe 5 and is sprayed out through the first nozzles 9, so that a plurality of first nozzles 9 face the conveying surface that has been turned over and has no materials for flushing, and the impurities adhering to the conveying surface of the conveying belt 2 are cleaned, so that there are no impurities on the surface of the conveying belt 2 to be detected. Then, as the conveying belt 2 continues to move and passes through the air drying module, the externally connected air blowing device operates, so that the air knife 16 admits air, and a plurality of second nozzles 20 are aligned with the conveying surface that has been cleaned for air drying. And, as the conveying 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, so as to ensure the accuracy of the wear detection of the conveying belt 2.

[0022] It should be noted that the high-pressure water flushing device can be a high-pressure water flushing machine composed of a high-pressure plunger pump and a motor, etc., to ensure that the sprayed high-pressure water source has enough pressure to wash away the impurities adhering to the conveying surface of the conveying belt 2. The air blowing device can be an air compressor to ensure effective air drying of the conveying belt 2.

[0023] By arranging the water pipe 5 and the first nozzles 9, the impurities adhering to the conveying surface of the conveying belt 2 to be detected can be washed away, ensuring the accuracy of the surface to be detected during detection; by using the air knife 16 and the second nozzles 20, the washed conveying surface is air dried, further improving the detection accuracy.

[0024] As a preferred technical solution of the present invention, a cleaning structure is connected between the water pipe 5 and the air 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. A brush 14 is connected to the top of the brush plate 13, and the bristles of the brush 14 abut against the conveying surface of the conveying belt 2.

[0025] Specifically, after the surface to be detected of the conveying belt 2 is washed, the conveyor belt continues to move. At this time, the surface to be detected will pass through the cleaning structure, and the brush 14 will brush the surface to be detected after cleaning, ensuring that the remaining stubborn impurities are brushed off again, and further improving the cleanliness of the surface to be detected and improving the accuracy of the detected data.

[0026] As a preferred technical solution of the present invention, a T-shaped groove 23 is opened on the outer wall of the brush plate 13, and a T-shaped plate 17 fixedly connected to the bottom of the brush 14 is inserted into the T-shaped groove 23, and the outer wall of the T-shaped plate 17 is connected to the brush plate 13 by a fastening bolt.

[0027] Specifically, in order to ensure that the brush 14 can be conveniently 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 groove 23 on the brush plate 13, and then the brush 14 can be replaced. During installation, only the T-shaped plate 17 at the lower end of the brush 14 needs to be snap-fitted with the T-shaped groove 23 on the brush plate 13, and then the fastening bolts are tightened to ensure the stability of the brush 14 on the brush plate 13.

[0028] As a preferred technical solution of the present invention, a scraping structure is further connected between the brush 14 and the air knife 16. The scraping structure includes a scraping plate 15. L-shaped columns 21 are connected to the bottoms of both ends of the scraping plate 15, and the L-shaped columns 21 are fixedly connected to the outer wall of the brush plate 13.

[0029] Specifically, after the conveyor belt 2 to be detected after flushing passes through the brushing of the brush 14, it will pass through the scraping plate 15. By using the scraping plate 15, on the one hand, the stubborn impurities remaining on the moving conveyor belt 2 can be peeled off, and on the other hand, the water stains can be scraped off, so as to ensure the improvement of the air drying efficiency of the subsequent air knife 16 and the second nozzle 20 and ensure the drying effect.

[0030] In addition, the arrangement of the scraping plate 15, the brush 14 and the brush plate 13 can not only remove the stubborn impurities remaining on the surface of the conveyor belt and play an auxiliary cleaning role, but also have a shielding and protection function. Specifically, the scraping plate 15, the brush 14 and the brush plate 13 can effectively block the splashing generated after the flushing water sprayed by the first nozzle 9 is mixed with the impurities, prevent the dirty water from adhering to the detection end of the thickness detector 4, thereby avoiding the decrease in detection sensitivity caused by pollution, and ensuring the accuracy and stability of the detection result.

[0031] As a preferred technical solution of the present invention, a chute 12 is provided inside the vertical column of the L-shaped column 21. A sliding column 22 slidably connected to the chute 12 is fixedly connected to the bottom of the scraping plate 15. A first spring 19 is fixedly connected to the bottom surface of the end of the sliding column 22 located inside the chute 12, and the bottom surface of the first spring 19 is fixedly connected to the bottom surface of the chute 12.

[0032] Specifically, in order to ensure good peeling effect of the impurities remaining on the conveying surface of the conveyor belt 2 by the scraping plate 15, when the scraping plate 15 is in use, the sliding column 22 at the bottom of the scraping plate 15 will slide in the chute 12 inside the L-shaped column 21. Due to the elastic potential energy of the first spring 19, the sliding column 22 can always be pushed upward, ensuring that the scraping plate 15 can always scrape along the conveying surface of the conveyor belt 2, and making the effect of peeling stubborn impurities better.

[0033] As a preferred technical solution of the present invention, a marking structure is further connected between the two brackets 8. The marking structure is located on the outer side of the thickness detector 4 away from the air knife 16. The marking structure includes a fixing box 6. A plurality of lifting probes 27 are slidably connected in the fixing box 6. The top of each lifting probe 27 passes through the fixing box 6 and abuts against the conveying surface of the conveying belt 2. One end of the lifting probe 27 located in the fixing box 6 is fixedly connected with a second spring 36, and the second spring 36 is fixedly connected with the bottom surface of the fixing box 6. A rack plate 28 is fixedly connected to the outer wall of each lifting probe 27. The outer side of the rack plate 28 is meshed with a gear 29. The axis of the gear 29 is fixedly connected with a central shaft 33. One end of the central shaft 33 is rotatably connected with a fixing frame 35. A paint spraying structure is connected to the top surfaces of the two brackets 8.

[0034] Specifically, after the thickness detector 4 detects, it is impossible to mark according to the wear at the corresponding position. Therefore, when the conveying belt 2 continuously moves, the lifting probe 27 is affected by the elastic potential energy of the second spring 36 in the fixing box 6, so that the top of the lifting probe 27 always abuts against the cleaned surface of the conveying belt 2. When the belt passes by, the probe generates a displacement according to the wear depth of the surface, that is, the deeper the wear, the greater the rising amplitude of the probe. When the lifting probe 27 moves upward, the lifting probe 27 drives the rack plate 28 to rise. The rack plate 28 is meshed with the gear 29, and the gear 29 drives the central shaft 33 to rotate in the fixing frame 35. When rotating, it can trigger the paint spraying structure to spray and mark the worn position on the conveying belt of the conveying belt 2, so that when the worker repairs later, it is clear that the marked position is the worn position, and at the same time, it is convenient for the worker to follow different repair methods according to different color marks.

[0035] As a preferred technical solution of the present invention, the paint spraying structure includes two paint boxes 7. A plurality of third nozzles 26 are connected to the top surfaces of the two paint boxes 7. The number of the third nozzles 26 at the top of each paint box 7 corresponds to the number of the lifting probes 27. An electromagnetic valve 31 for opening and closing the third nozzle 26 is connected to each third nozzle 26. The outer wall of the paint box 7 is externally connected to a spraying device through a feed pipe. A triggering structure for opening and closing the electromagnetic valve 31 is connected to the outer side of the central shaft 33.

[0036] As a preferred technical solution of the present invention, the triggering structure includes a trigger piece 30, an extension plate 34 and a trigger plate 24. An extension plate 34 is fixedly connected to one end of the central shaft 33 away from the fixing frame 35. An arc plate 32 is fixedly connected to one side of the fixing frame 35. Two L-shaped trigger plates 24 are fixedly connected to the outer wall of the arc plate 32. Trigger pieces 30 are connected to the opposite surfaces of the trigger plate 24 and the extension plate 34. The trigger piece 30 located on the trigger plate 24 is electrically connected to the corresponding electromagnetic valve 31 through a cable.

[0037] Specifically, when the gear 29 rotates, it drives the central shaft 33 to rotate within 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 to come into contact with the trigger piece 30 on the trigger plate 24. Since the trigger plate 24 is fixed to the arc plate 32, and the arc plate 32 is fixedly connected to the fixed frame 35, when the gear 29 rotates, the arc plate 32 remains stationary, the trigger plate 24 remains stationary, and the trigger piece 30 on the extension plate 34 will come into contact with the trigger pieces 30 on the two trigger plates 24.

[0038] When the wear level reaches a certain threshold, the lifting probe 27 rises to a certain distance. Under the meshing of the rack plate 28 and the gear 29, the extension plate 34 rotates, causing the trigger piece 30 on the extension plate 34 to contact the trigger piece 30 on the first trigger plate 24. At this time, the two trigger pieces 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, enabling the external spraying device to spray out the pigment, and a mark appears at the corresponding position.

[0039] When the wear level 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. When the extension plate 34 continues to rotate, it will disengage from the first trigger plate 24 and come into contact with the trigger piece 30 on the second extension plate 34. At this time, the solenoid valve 31 connected to this trigger piece 30 will be opened, causing another set of colored pigments to be sprayed out; the colors of the two sets of pigments can be yellow and red, respectively representing different wear levels. The color sprayed out by the first opened third nozzle 26 is yellow, and the color sprayed out by the later opened third nozzle 26 should be red, and this pigment is non-corrosive and degradable to prevent corrosion of the conveyor belt 2.

[0040] Since there are multiple third nozzles 26 corresponding to the lifting probe 27 on the two paint boxes 7, different wear levels at different positions on the conveying surface of the conveyor belt 2 can be reflected. Using the above structure, it can conveniently detect different wear levels when the conveyor belt 2 needs to be repaired, making subsequent repairs more convenient.

[0041] In addition, since different wear levels at different positions of the belt will cause the lifting probe 27 to rise and fall repeatedly, based on this, the trigger piece 30 on the extension plate 34 will repeatedly contact and disengage from the trigger pieces 30 on the two trigger plates 24. There is a possibility that the pigments sprayed in the two wear states will be covered, which can also clarify different degrees of wear at different positions.

[0042] As a preferred technical solution of the present invention, a U-shaped cover 25 is fixedly connected to the outer wall of the fixed box 6, and a plurality of 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.

[0043] Specifically, the setting of the U-shaped cover 25 can facilitate the protection of several 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.

[0044] As a preferred technical solution of the present invention, a U-shaped pressing plate 37 is slidably connected to the top surface of the U-shaped cover 25, and the bottom surface of the U-shaped pressing plate 37 abuts against the top surfaces of a plurality of lifting probes 27.

[0045] Specifically, when the lifting probes 27 are not required to be used, in order to prevent the lifting probes 27 from being always in contact with the conveyor belt 2 and being worn, the U-shaped pressing plate 37 can be slid, so that the U-shaped pressing plate 37 translates on the top surface of the U-shaped cover 25, and the transverse plate of the U-shaped pressing plate 37 is slid out to abut against the top surfaces of a plurality of lifting probes 27. In this way, the lifting probes 27 can be pressed down to prevent the tops of the lifting probes 27 from being damaged. And the U-shaped pressing plate 37 is not retracted under the upward extrusion force of the lifting probes 27, thereby ensuring that the U-shaped pressing plate 37 always limits a plurality of lifting probes 27.

[0046] In the above structure, the corresponding structure is used to complete the actions of flushing, cleaning, air drying, detecting and marking the conveyor belt 2, which not only effectively ensures the accuracy of the conventional thickness detector 4 during detection, but also can mark different positions and different wear depths on the clean conveyor surface, facilitating subsequent different repair work for different marks.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
