Technical Field

[0001] This invention relates to the field of dust suppression technology in open-pit mines, and more specifically, to a dust suppression device. Background Technology

[0002] Open-pit mining involves stripping away the topsoil and surrounding rock covering the ore body, transporting the waste rock to a spoil heap, and directly extracting ore from the exposed ore body. The mining process generates a large amount of dust, leading to severe dust pollution around the mine. Furthermore, the frequent passage of vehicles carrying ore and sand within the mine, coupled with poor road conditions, further exacerbates dust pollution.

[0003] In existing technologies, most dust reduction is achieved by manually spraying water. However, manual dust suppression is not only ineffective but may also result in uneven dust distribution. Furthermore, it requires a significant amount of manpower and resources to adjust the dust suppression devices, making it impractical. Summary of the Invention

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please refer to Figures 1 to 7The present invention provides a dust suppression device, including a vertical dust suppression mechanism 100 and an adjustable dust suppression mechanism 200. The vertical dust suppression mechanism 100 is used to suppress dust in a target area. The adjustable dust suppression mechanism 200 is disposed on the vertical dust suppression mechanism 100 and includes a first dust suppression component 210. The first dust suppression component 210 has an initial position and a dust suppression position for suppressing dust on a target object. The first dust suppression component 210 is movably disposed relative to the vertical dust suppression mechanism 100 between the initial position and the dust suppression position. Specifically, the target area is an open-pit mine area where dust suppression operations are required, and the target object is a transport vehicle moving within the open-pit mine area.

[0040] In addition, to control the start or stop of the dust suppression mechanism 200, the dust suppression device also includes a trigger mechanism 300. The trigger mechanism 300 is connected to the first dust suppression component 210 and sends a control signal to the first dust suppression component 210 to control the movement of the first dust suppression component 210 between the initial position and the dust suppression position. When the target object moves to the area where the trigger mechanism 300 is located, after the trigger mechanism 300 senses the position signal of the target object, it sends a start signal to the first dust suppression component 210. The first dust suppression component 210 moves to the dust suppression position and begins to perform dust suppression operation on the target object. When the target object leaves the area where the trigger mechanism 300 is located, the trigger mechanism 300 sends a stop dust suppression signal to the first dust suppression component 210. The first dust suppression component 210 pauses the dust suppression operation and moves back to the initial position.

[0041] The dust suppression device of this invention includes a vertical dust suppression mechanism 100, an adjustable dust suppression mechanism 200, and a triggering mechanism 300. The vertical dust suppression mechanism 100 suppresses dust in a target area, the adjustable dust suppression mechanism 200 suppresses dust on a target object, and the triggering mechanism 300 controls the activation of the adjustable dust suppression mechanism 200. The vertical dust suppression mechanism 100 and the adjustable dust suppression mechanism 200 are controlled independently, allowing the vertical dust suppression mechanism 100 to operate or both to operate simultaneously according to actual needs. Furthermore, the triggering mechanism 300 senses the position information of the target object, thereby achieving automatic control of the adjustable dust suppression mechanism 200. When the target object passes through the sensing area of ​​the triggering mechanism 300, the triggering mechanism 300 senses the position information of the target object and automatically controls the activation or deactivation of the adjustable dust suppression mechanism 200. This solves the problems of poor dust suppression effect and limited practicality in existing technologies that require manual dust suppression.

[0042] In order to perform dust suppression operation on the target area, the vertical dust suppression mechanism 100 in this embodiment includes a first conveying pipe 5 and a second dust suppression component 120. The first conveying pipe 5 is connected to the second dust suppression component 120. The dust suppression medium is conveyed into the second dust suppression component 120 through the first conveying pipe 5, so that the dust suppression medium is sprayed from the second dust suppression component 120 to the target area for dust suppression.

[0043] Similarly, in order to perform dust suppression on the target object, the dust suppression adjustment mechanism 200 in this embodiment also includes a second conveying pipe 20, which is connected to the first dust suppression component 210. The second conveying pipe 20 conveys dust suppression medium into the first dust suppression component 210, allowing the dust suppression medium to be sprayed from the first dust suppression component 210 onto the target area for dust suppression. Specifically, at least a portion of the second conveying pipe 20 is a flexible component; optionally, at least a portion of the second conveying pipe 20 is a corrugated pipe to facilitate expansion and contraction with the movement of the first dust suppression component 210. Specifically, the section of the second conveying pipe 20 between the vertical dust suppression mechanism 100 and the dust suppression adjustment mechanism 200 is a corrugated pipe.

[0044] Furthermore, in order to transport the dust-suppressing medium to the first conveying pipeline 5 and the second conveying pipeline 20, the dust-suppressing device also includes a conveying main pipe 4, the output end of which is connected to the first conveying pipeline 5 and / or the second conveying pipeline 20 respectively, so that the dust-suppressing medium is transported from the conveying main pipe 4 to the first conveying pipeline 5 and / or the second conveying pipeline 20.

[0045] like Figure 4 As shown, to facilitate adjustment of the conveying pipeline, the dust suppression mechanism 200 also includes a switching component 15. The switching component 15 is mounted on the output pipe of the main conveying pipe 4 and is movably mounted. The switching component 15 is provided with a first channel 16 and a second channel 17. The two ends of the first channel 16 are respectively connected to the main conveying pipe 4 and the first conveying pipeline 5, so that the switching component 15 is in the first connected position. The two ends of the second channel 17 are respectively connected to the main conveying pipe 4 and the second conveying pipeline 20, so that the switching component 15 is in the second connected position. When the switching component 15 is in the first connected position, the dust suppression medium in the main conveying pipe 4 is conveyed to the first conveying pipeline 5; when the switching component 15 is in the second connected position, the dust suppression medium in the main conveying pipe 4 is conveyed to the second conveying pipeline 20.

[0046] Furthermore, in order to limit the switching component 15 and enable it to switch between the first and second communication positions, thereby facilitating the control of the position of the switching component 15, the dust suppression adjustment mechanism 200 also includes a limiting component 14 and a push-pull component 13. The push-pull component 13 passes through the limiting component 14, and one end of the push-pull component 13 with a push rod is connected to the side of the switching component 15 away from the second channel 17. The end of the push-pull component 13 away from the push rod is fixedly installed on the vertical dust suppression mechanism, so that the movement of the switching component 15 can be controlled by the extension and retraction of the push rod of the push-pull component 13. A limiting cavity 6 is provided inside the limiting component 14, and the switching component 15 is movably disposed within the limiting cavity 6. The limiting component 14 is provided with a first passage, a second passage, and a third passage. The first passage is connected to the input end of the first conveying pipe 5, the second passage is connected to the input end of the second conveying pipe 20, and the third passage is connected to the output end of the main conveying pipe 4.

[0047] Specifically, the limiting component 14 includes a limiting frame, which includes a first side frame, a second side frame, a third side frame, and a fourth side frame connected sequentially along the circumference of the limiting frame body. The first side frame, the second side frame, the third side frame, and the fourth side frame are connected sequentially and surround each other to form a limiting cavity 6.

[0048] The first passage and the third passage are respectively set on the first frame and the third frame. The liquid inlet of the first passage and the liquid outlet of the third passage are arranged opposite to each other to connect the main conveying pipe 4, the first channel 16 and the first conveying pipeline 5. When the switching component 15 is in the first connected position, the dust-suppressing medium in the main conveying pipe 4 flows through the third passage, the first channel 16 and the first passage in sequence and then flows into the first conveying pipeline 5. Specifically, the first channel 16 is an I-type channel.

[0049] Similarly, the second and third passages are respectively installed on the second and third frames to connect the main conveying pipe 4, the second channel 17 and the second conveying pipeline 20. When the switching component 15 is in the second connected position, the dust-suppressing medium in the main conveying pipe 4 flows through the third passage, the second channel 17 and the third passage in sequence, and then flows into the second conveying pipeline 20. Specifically, the second channel 17 is an L-shaped channel, which is used to connect the second and third passages in the vertical direction.

[0050] like Figure 1 and Figure 2As shown, in order to improve the dust suppression effect on the target object, the first dust suppression component 210 in this embodiment includes a support component 18, a rotating component 19, and a plurality of first nozzles 21. The rotating component 19 is mounted on the vertical dust suppression mechanism 100, and the support component 18 is rotatably mounted on the vertical dust suppression mechanism 100 via the rotating component 19. Specifically, the rotating component 19 is a drive motor, the support component 18 is a hollow support rod, and the second conveying pipe 20 passes through the support rod; the plurality of first nozzles 21 are spaced apart along the extension direction of the support component 18, the second conveying pipe 20 has a plurality of output ports, and the support component 18 is spaced apart along the extension direction of the support component 18, each corresponding to a plurality of ports on the second conveying pipe 20, thereby the plurality of first nozzles 21 are correspondingly mounted on the plurality of ports on the support component 18.

[0051] In order to reduce dust in multiple target areas, the vertical dust reduction mechanism 100 in this embodiment is in multiple groups. The multiple groups of vertical dust reduction mechanisms 100 are set at intervals along a predetermined trajectory. Specifically, the predetermined trajectory is determined according to the actual dust reduction situation in the open-pit mine, and can be set as a straight trajectory, a C-shaped trajectory, or a corrugated trajectory, etc.

[0052] Each set of vertical dust suppression mechanisms 100 includes a first vertical dust suppression mechanism 101 and a second vertical dust suppression mechanism 102 arranged opposite to each other. The first vertical dust suppression mechanism 101 is provided with a first adjusting dust suppression mechanism 201, and the second vertical dust suppression mechanism 102 is provided with a second adjusting dust suppression mechanism 202. This arrangement can expand the dust suppression range of the dust suppression device and enhance the dust suppression effect of the dust suppression device.

[0053] Furthermore, to reinforce the dust suppression mechanism 200, when the first dust suppression mechanism 201 and the second dust suppression mechanism 202 are in the dust suppression position, the first dust suppression mechanism 201 is connected to the second dust suppression mechanism 202. The dust suppression device also includes a connecting component 22, which includes a first connecting component 24 and a second connecting component 26. The first connecting component 24 is located at the end of the support component 18 in the first dust suppression mechanism 201 that is away from the first vertical dust suppression mechanism 101; the second connecting component 26 is located at the end of the support component 18 in the second dust suppression mechanism 202 that is away from the second vertical dust suppression mechanism 102. The first connecting component 24 and the second connecting component 26 are connected to ensure that the first dust suppression assembly 210 is in the dust suppression position.

[0054] Specifically, in order to connect the first dust-reducing mechanism 201 and the second dust-reducing mechanism 202, the height of the first dust-reducing mechanism 201 when it is in the dust-reducing position is the same as the height of the second dust-reducing mechanism 202 when it is in the dust-reducing position.

[0055] like Figure 5As shown, the connecting component 22 in this embodiment further includes a socket portion 23, an insertion portion 25, and a limiting spring 27. The socket portion 23 includes a first socket portion and a second socket portion, and the insertion portion 25 includes a first insertion portion and a second insertion portion. The first socket portion and the second insertion portion are disposed on a first connecting end face where the first connecting component 24 and the second connecting component 26 are connected. The second socket portion and the first insertion portion are disposed on a second connecting end face where the second connecting component 26 and the first connecting component 24 are connected. The first insertion portion is inserted into the first socket portion, so that the first connecting component 24 and the second connecting component 26 are in a connected state.

[0056] Preferably, the first connecting component 24 and the second connecting component 26 are connected by an electromagnet, and a fixed electromagnet is provided in the first insertion part and the second insertion part respectively, and a movable metal rod is provided in the first insertion part and the second insertion part respectively. Specifically, the moving rod is made of metals such as iron, nickel, or cobalt. Along the length of the moving rod, a first stop block and a second stop block are spaced apart on the rod body. The first stop block is located at the first end of the moving rod. A limiting spring 27 is sleeved on the moving rod and located between the first stop block and the second stop block. The two ends of the limiting spring 27 are connected to the first stop block and the second stop block, respectively. A contact block is provided at the second end of the moving rod. The contact block is made of metal and is attracted to the electromagnet so that the first connecting part 24 and the second connecting part 26 are in the connected position. At this time, as the contact block drives the moving rod to move towards the electromagnet, it compresses the limiting spring 27. When the dust removal of the target object is completed, the electromagnet is de-energized, and the contact block moves to the initial position under the action of the elastic restoring force of the limiting spring 27, so that the first connecting part 24 and the second connecting part 26 are separated.

[0057] To facilitate disassembly of the vertical dust suppression mechanism 100, the vertical dust suppression mechanism 100 includes a mounting base 2 and a supporting column 3. The supporting column 3 is mounted on the mounting base 2 and detachably connected to the mounting base 2. The adjustable dust suppression mechanism 200 is mounted on the supporting column 3. This configuration allows the vertical dust suppression mechanism 100 to be easily moved to different target areas and facilitates maintenance. The second channel 17 is an L-shaped channel, which facilitates the direct flow of the dust suppression medium into the second conveying pipeline 20, and makes it easy to mount the second conveying pipeline 20 on the supporting column 3.

[0058] like Figure 1 and Figure 2As shown, the second dust suppression component 120 includes a liquid supply housing 11 and a second nozzle 12. The liquid supply housing 11 is located at the end of the support column 3 away from the mounting base 2. There are multiple second nozzles 12, which are spaced apart along the circumferential direction of the liquid supply housing 11 and communicate with the liquid supply chamber of the liquid supply housing 11. The output end of the first conveying pipeline 5 is connected to the liquid supply chamber of the liquid supply housing 11 so as to convey the dust suppression medium into the liquid supply housing 11 through the first conveying pipeline 5.

[0059] Furthermore, in order to expand the dust suppression range of the vertical dust suppression mechanism 100, the vertical dust suppression mechanism 100 also includes a drive assembly 110. The drive assembly 110 is disposed at the end of the support column 3 away from the mounting base 2. The liquid supply housing 11 is rotatably disposed on the drive assembly 110, so that the second nozzle 12 disposed on the liquid supply housing 11 is rotatably disposed around the first axis, thereby allowing the dust suppression medium to be sprayed to the target area through the second nozzle 12.

[0060] Specifically, the drive assembly 110 in this embodiment includes a base 7, a drive component 8, a drive gear 9, and a driven gear 10. The base 7 is fixedly installed at the end of the support column 3 away from the mounting base 2. The drive component 8 is disposed on the base 7 and includes a drive body and an output shaft. The drive body is fixedly installed on the base 7. The drive gear 9 is sleeved on the output shaft of the drive component 8, and the driven gear 10 is sleeved on the bottom of the liquid supply housing 11. The drive gear 9 and the driven gear 10 mesh with each other. The drive component 8 drives the drive gear 9 to drive the driven gear 10, thereby causing the liquid supply housing 11 to rotate around the first axis.

[0061] Preferably, the driving component 8 is a drive motor, and a sealed bearing is installed at the bottom of the liquid supply housing 11 to prevent accidents such as leakage during the rotation of the liquid supply housing 11.

[0062] like Figure 3 and Figure 6 As shown, in order to control the start or stop of the dust suppression component, the triggering mechanism 300 includes a sensing component 310 and a sensing component 320. The sensing component 310 is used to sense the position information of the target object. The sensing component 320 is connected to the sensing component 310 and the first dust suppression component 210 respectively, so that after the sensing component 310 senses the target object, it sends a start signal to the first dust suppression component 210 to control the first dust suppression component 210 to move to the dust suppression position.

[0063] Furthermore, the dust suppression device in this embodiment also includes a supporting base 1, a vertical dust suppression mechanism 100 is disposed on the supporting base 1, and an installation groove 28 is provided on the supporting base 1. The sensing component 310 includes a pressure plate 29 and a first sensing component 38. The pressure plate 29 is disposed in the installation groove 28 and is movably disposed in the vertical direction. When the target object moves to the area where the pressure plate 29 is located, the pressure plate 29 is pressed down by gravity, thereby triggering the triggering mechanism 300. The first sensing component 38 is connected to the pressure plate 29 and is moved by the pressure plate 29.

[0064] Specifically, the pressure plate 29 has arc-shaped grooves at both ends, with the openings of the arc-shaped grooves located on the end faces of the pressure plate 29. A limiting plate is provided on the groove wall of the mounting groove 28, extending from the groove wall towards the center of the mounting groove 28. At least a portion of the limiting plate is inserted into the arc-shaped groove. The arc-shaped groove has a first contact surface that fits against the panel of the limiting plate, which is inclined towards the bottom surface of the pressure plate 29. The limiting plate has a second contact surface that fits against the first contact surface, which is inclined towards the bottom surface of the mounting groove 28. This ensures that the limiting plate and the arc-shaped groove fit tightly together. During the downward movement of the pressure plate 29 under pressure, the limiting plate prevents external impurities from entering the mounting groove 28 and affecting its normal operation.

[0065] Additionally, the sensing component 320 includes a second sensing element 39, which is disposed within the mounting groove 28. The second sensing element 39 senses the position information of the first sensing element 38. The second sensing element 39 is connected to the first dust suppression component 210 so that after sensing the position information of the first sensing element 38, the second sensing element 39 contacts the first sensing element 38 and sends a start signal to the first dust suppression component 210. Specifically, both the first sensing element 38 and the second sensing element 39 are electrical contact elements.

[0066] like Figure 3 As shown, the sensing component 310 in this embodiment also includes a base 31 and an insertion component 36. The base 31 is disposed in the mounting groove 28 and has a first receiving cavity 37. The second sensing component 39 is disposed in the first receiving cavity 37. The insertion component 36 is connected to the pressure plate 29. At least a portion of the insertion component 36 is opposite to the first receiving cavity 37. The pressure plate 29 drives the insertion component 36 to extend into or out of the first receiving cavity 37. The first sensing component 38 is disposed on the insertion component 36.

[0067] Furthermore, the sensing component 310 also includes a first transmission component 33 and a second transmission component 34. The first transmission component 33 is connected to the pressure plate 29 and has a first guide end face. The second transmission component 34 is connected to the insertion component 36 and has a second guide end face that fits against the first guide end face. Both the first and second guide end faces are inclined surfaces. Specifically, as shown... Figure 7 As shown, a groove is provided on the second guide end face of the second transmission component 34; a protruding slider that matches the groove is provided on the first guide end face of the first transmission component 33, and the protruding slider is inserted into the groove.

[0068] During the process of the pressure plate 29 driving the first transmission component 33 to press down, the first transmission component 33 pushes the second transmission component 34 to move through the first guide end face, so that the second transmission component 34 pushes the insertion component 36 to move into the first receiving cavity 37, so that the second sensing component 39 contacts the first sensing component 38.

[0069] Furthermore, a second receiving cavity 32 is provided inside the base 31, and a second transmission component 34 is disposed inside the second receiving cavity 32. The sensing component 310 also includes a first elastic component 35 and a second elastic component 30. The two ends of the first elastic component 35 are respectively connected to the side walls of the second transmission component 34 and the second receiving cavity 32. The elastic restoring force of the first elastic component 35 drives the second transmission component 34 and the insertion component 36 to move away from the first receiving cavity 37. The two ends of the second elastic component 30 are respectively connected to the bottom surface of the pressure plate 29 and the mounting groove 28. The elastic restoring force of the second elastic component 30 drives the pressure plate 29 to move away from the bottom surface of the mounting groove 28.

[0070] Preferably, both the first elastic component 35 and the second elastic component 30 are springs.

[0071] The specific implementation process of the triggering mechanism 300 in this embodiment is as follows: When the target object passes the pressure plate 29, pressure is applied to the pressure plate 29 to move downward. The pressure plate 29 squeezes the second elastic component 30 and the first transmission component 33. Since the inclined surfaces of the first transmission component 33 and the second transmission component 34 are connected by a protruding slider and a groove, during the downward pressing process of the pressure plate 29, the first transmission component 33 drives the second transmission component 34 to move horizontally and stretches the first elastic component 35. At this time, the second transmission component 34 drives the insertion component 36. Inserted into the first receiving cavity 37, the first sensing component 38 on the insertion component 36 contacts the second sensing component 39 in the first receiving cavity 37, causing the triggering mechanism 300 to form a closed circuit. At the same time, it sends an electrical signal to the rotating component 19, the connecting component 22, and the push-pull component 13, causing the rotating component 19, the connecting component 22, and the push-pull component 13 to start running. This causes the first dust-reducing component 210 to move to the dust-reducing position, and causes the dust-reducing medium to be sprayed from the first nozzle 21 to the outside, forming a water curtain, thereby performing a dust-reducing operation on the target object passing through the triggering mechanism 300.

[0072] like Figure 1 As shown in Figure 2, in order to facilitate the supply of dust-suppressing medium to the vertical dust-suppressing mechanism 100 and the adjustable dust-suppressing mechanism 200, the dust-suppressing device also includes a liquid supply mechanism 400, which is connected to the input end of the conveying main pipe 4 to supply dust-suppressing medium to the vertical dust-suppressing mechanism 100 and the adjustable dust-suppressing mechanism 200.

[0073] Specifically, the liquid supply mechanism 400 in this embodiment includes a media storage tank 40 and a liquid supply component 41. The media storage tank 40 is disposed in the clearance cavity below the bearing base 1 and is used to store the dust-suppressing medium for easy operation. The liquid supply component 41 is a driving pump and is disposed on the main delivery pipe 4. It is used to provide power to the dust-suppressing medium in the media storage tank 40 so as to deliver it to the first dust-suppressing component 210 and / or the second dust-suppressing component 120.

[0074] Furthermore, to facilitate observation of the remaining liquid level in the media storage tank 40 and timely adjustment, the liquid supply mechanism 400 also includes a liquid level plate 42, an indicator rod 43, and a scale 44. The liquid level plate 42 is disposed inside the media storage tank 40, and the scale 44 is disposed on the bearing surface 1 at an easily observable position. The first end of the indicator rod 43 is connected to the liquid level plate 42, and the second end of the indicator rod 43 is disposed on the graduated side of the scale 44. Specifically, the liquid level plate 42 is a float plate, floating on the surface of the dust-suppressing medium, and the scale 44 is marked with the highest and lowest liquid levels. When the liquid level in the media storage tank decreases, the liquid level plate 42 causes the indicator rod 43 to move downwards. By observing the position of the second end of the indicator rod 43 on the scale 44, the remaining liquid level in the media storage tank 40 can be observed, allowing for a determination of whether adjustment is necessary. Preferably, the dust-suppressing medium is water.

[0075] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0076] The dust suppression device provided by this invention, through the provision of a detachable vertical dust suppression mechanism 100 with a rotatable second dust suppression component 120, can perform dust suppression operations on target areas according to the actual conditions of the open-pit mine; through the provision of an adjustable dust suppression mechanism 200 having a first dust suppression component 210 that can rotate between an initial position and a dust suppression position, it can perform dust suppression operations on target objects moving in the open-pit mine; through the provision of a trigger mechanism 300 connected to the adjustable dust suppression mechanism 200, it can control the opening and closing of the adjustable dust suppression mechanism 200. This solves the problems of poor dust suppression effect and limited practicality in the prior art due to the need for manual dust suppression, resulting in a dust suppression device with characteristics such as automatic operation, wide dust suppression range, and good dust suppression effect.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
