Description

Technical Field

[0001] This utility model relates to the field of continuous mining machine technology, and more specifically, it relates to a combined atomizing dust removal device for continuous mining machines. Background Technology

[0002] Continuous coal mining machines (CCMs), also known as continuous coal mining machines, are one of the core pieces of equipment in fully mechanized underground coal mining. They are mainly used for efficient coal mining and roadway excavation in thin and medium-thick coal seams. Through a cutting mechanism, they continuously crush and load the coal seam, and in conjunction with transfer and transportation equipment, they achieve integrated coal mining and transportation operations. They are characterized by high production efficiency and a high degree of automation, and are widely used in the intensive production of modern mines. During the coal transfer process, collisions, friction, and impacts from drops between coal blocks generate a large amount of secondary dust, which is usually removed by atomizing dust removal devices.

[0003] Existing combined atomizing dust removal devices for continuous mining machines have been found to have the following issues during use:

[0004] 1. Disassembly and maintenance are difficult. The existing fixed structure requires loosening the bolts distributed on both sides of the frame one by one. When operating in the confined space underground, the use of tools is limited, and the bolts are easy to rust and difficult to disassemble, resulting in an excessively long maintenance cycle, which affects the continuous operation of the continuous mining machine and thus leads to poor practicality.

[0005] 2. Fixed spray angle: As the amount of coal conveyed and the drop on the conveying device change dynamically with the progress of coal mining, the range and direction of dust diffusion also change accordingly. However, the angle of the atomizing nozzle of the existing device is not adjustable, and the spray range on both sides is fixed. When the coal piles up to one side or the drop increases, it is easy to have insufficient dust coverage on one side and excessive water mist on the other side, which forms coal sludge, resulting in unstable dust removal efficiency. Utility Model Content

[0006] (1) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides a combined atomizing dust removal device for continuous mining machines to solve the technical problems of difficult disassembly and maintenance, as well as fixed spray angle mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a combined atomizing dust removal device for a continuous mining machine, comprising a mounting base, a conveying device provided on the inner side of the top of the mounting base, a fixing mechanism provided at both ends of the top of the mounting base, a fixing plate provided at both ends of the top of the mounting base through the fixing mechanism, a water pump device evenly provided at one end of each of the two sets of fixing plates, an angle adjustment mechanism provided at the opposite end of each of the two sets of fixing plates, a connecting plate provided at the opposite end of each of the two sets of fixing plates through the angle adjustment mechanism, an atomizing nozzle provided at the other end of each of the two sets of connecting plates, and two sets of conveying hoses evenly provided at the top output end of each of the two sets of water pump devices, and the other ends of each of the four sets of conveying hoses passing through the connecting plate and connected to one end of the atomizing nozzle.

[0010] The present invention is further configured such that the angle adjustment mechanism includes four sets of support rods, each of the two sets of fixed plates has a connecting block at the top of one opposite end, and each of the two sets of connecting blocks has a first hinge seat on both the front and rear sides of one opposite end. The top of one end of each of the two sets of connecting plates is hinged to the corresponding two sets of first hinge seats. A driving assembly is provided at the bottom of one opposite end of each of the two sets of fixed plates, and a sliding plate is slidably mounted on the bottom of one opposite end of each of the two sets of fixed plates via the driving assembly. Second hinge seats are provided at both ends of the four sets of support rods, and the front and rear sides of one opposite end of each of the two sets of sliding plates are hinged to one end of the support rod via the second hinge seats. Both sets of connecting plates are hinged at one end to the other end of the support rod via the second hinge seat. The cooperation of the four sets of support rods and the two sets of hinge seats forms a stable triangular support structure, ensuring smooth rotation of the connecting plates and avoiding spray deviation caused by the shaking of the atomizing nozzles. This solves the problem of uneven coverage in traditional fixed-angle devices. The hinge design between the connecting plates and the first and second hinge seats allows for a wider angle adjustment range, which can adapt to the dust diffusion characteristics at different positions of the conveying device and improve the targeting of dust removal. The symmetrically distributed angle adjustment mechanism allows the atomizing nozzles on both sides of the conveying device to adjust synchronously, ensuring a balanced overall dust removal effect.

[0011] This invention is further configured such that the driving assembly includes two sets of driving motors. Each of the two sets of fixed plates has a groove at one end of its bottom. A reciprocating screw is rotatably mounted within the groove of each of the two sets of fixed plates. The driving motors are mounted on the top of each of the two sets of fixed plates. The bottom output ends of the two sets of driving motors pass through the fixed plates and connect to the top of the reciprocating screws. A first slider is threadedly connected to the outer side of each reciprocating screw, and the outer side of the first slider is slidably connected to the groove of the fixed plate. One end of each of the two sets of first sliders is connected to one end of a sliding plate. The threaded transmission between the reciprocating screw and the first slider provides precise displacement control, enabling fine-tuning of the atomizing nozzle angle. This solves the problem of large deviations during manual angle adjustment, ensuring accurate water mist coverage of the dust source. The driving motors provide automated power, allowing angle adjustment to be completed without manual intervention, adapting to the real-time dust removal needs of dynamic dust changes during continuous operation of the continuous mining machine. The sliding cooperation between the first slider and the groove provides stable guidance for the sliding plate, preventing jamming or offset during adjustment.

[0012] This utility model is further configured such that the fixing mechanism includes two sets of positioning blocks, each set of fixing plates has a positioning block at its bottom, and each set of mounting bases has a slot at both ends of its top. The bottom of each set of positioning blocks is engaged with a slot in the mounting base. Each set of mounting bases has a support plate at both ends, and each set of support plates has a sliding component at its top. Each set of support plates has a clamping plate slidably mounted on its top via the sliding component. Each set of clamping plates has a first locking block at one end opposite to the other. Each set of fixing plates has a pre-drilled hole at one end, and the outer sides of each set of first locking blocks are engaged with the pre-drilled holes in the fixing plates. The double-locking structure replaces the traditional bolt fastening, enabling rapid installation and disassembly of the fixing plates. This solves the problem of cumbersome disassembly caused by bolts in existing devices. The cooperation between the positioning blocks and the slots ensures accurate positioning of the fixing plates, avoiding misalignment between the atomizing nozzle and the conveying device due to offset, thus improving dust removal efficiency. The engagement of the first locking block with the pre-drilled hole enhances the connection strength of the fixing plates, resisting vibration and impact during continuous mining operations, and ensuring the stability of the device in harsh environments.

[0013] The present invention is further configured such that the sliding assembly includes two sets of connecting screws, each of the tops of the two sets of support plates is provided with a sliding groove, the connecting screws are rotatably disposed within the sliding grooves of the two sets of support plates, and the outer sides of the two sets of connecting screws are threadedly connected to second sliders, the bottoms of the two sets of second sliders are slidably connected to the sliding grooves of the support plates respectively, and the tops of the two sets of second sliders are respectively connected to the bottom of a set of clamping plates; the transmission structure of the connecting screws and the second sliders provides a stable driving force for the clamping plates, making the engagement or disengagement of the first locking block with the reserved hole smoother, and the self-locking characteristic of the threaded transmission ensures that the clamping plates will not loosen due to vibration after being fixed, thereby enhancing the connection reliability between the fixing plate and the mounting base. The structure is simple, and no special tools are required during operation; adjustment can be completed simply by rotating the connecting screws, improving the convenience of fixing plate assembly and disassembly.

[0014] The present invention is further provided with mounting brackets on the front and rear sides of the top of the two sets of fixing plates, and handles on the top of the two sets of mounting brackets; the handles solve the problem of difficult handling of the fixing plates and auxiliary components, and avoid unstable grip due to the smooth surface of the device.

[0015] The present invention is further configured such that one end of each of the two sets of connecting screws passes through a corresponding support plate and is provided with a rotating handle; the rotating handle increases the rotation radius of the connecting screw, and the handle design conforms to ergonomics, making it comfortable to hold and not easy to slip, ensuring stable force application during rotation.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a combined atomizing dust removal device for continuous mining machines, which has the following beneficial effects:

[0018] 1. The dual-clamping structure replaces the traditional bolt fastening, enabling rapid installation and disassembly of the fixing plate. This solves the problem of cumbersome disassembly caused by the reliance on bolts in existing devices. The cooperation between the positioning block and the slot ensures accurate positioning of the fixing plate during installation, avoiding misalignment between the atomizing nozzle and the conveying device due to offset, thus improving dust removal efficiency. The clamping of the first clamping block and the reserved hole enhances the connection strength of the fixing plate, resisting the vibration and impact during continuous mining machine operation, and ensuring the stability of the device in harsh environments.

[0019] 2. The cooperation of four sets of support rods and two sets of hinge seats forms a stable triangular support structure, ensuring smooth rotation of the connecting plate and avoiding spray deviation caused by the shaking of the atomizing nozzles. This solves the problem of uneven coverage in traditional fixed-angle devices. The hinged design of the connecting plate with the first and second hinge seats allows for a wider angle adjustment range. The drive component drives the sliding plate to slide, and the angle adjustment is achieved through mechanical transmission, replacing manual manipulation and reducing the labor intensity of downhole workers. It can adapt to the dust diffusion characteristics of different positions of the conveying device and improve the targeting of dust removal. The symmetrically distributed angle adjustment mechanism allows the atomizing nozzles on both sides of the conveying device to adjust synchronously, ensuring a balanced overall dust removal effect.

[0026] 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.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] Please see Figure 1-5 A combined atomizing dust removal device for a continuous mining machine includes a mounting base 1, a conveying device 2 disposed on the inner side of the top of the mounting base 1, a fixing mechanism disposed at both ends of the top of the mounting base 1, a fixing plate 3 disposed at both ends of the top of the mounting base 1 through the fixing mechanism, a water pump device 4 evenly disposed at one end of the two fixing plates 3, an angle adjustment mechanism disposed at the opposite end of the two fixing plates 3, a connecting plate 5 disposed at the opposite end of the two fixing plates 3 through the angle adjustment mechanism, an atomizing nozzle 6 disposed at the other end of the two connecting plates 5, and two sets of conveying hoses 7 evenly disposed at the top output end of the two sets of water pump devices 4, and the other ends of the four sets of conveying hoses 7 all pass through the connecting plate 5 and are connected to one end of the atomizing nozzle 6.

[0030] In this embodiment, during installation, the conveying device 2 on the inner side of the top of the mounting base 1 is responsible for conveying the coal blocks mined by the continuous mining machine. The two ends of the top of the mounting base 1 are fixed with the fixing plate 3 by the fixing mechanism to ensure that the device is stably installed on both sides of the conveying device 2. During operation, the water pump device 4 at one end of the fixing plate 3 is started, and the four sets of conveying hoses 7 at the top output end of the fixing plate 3 deliver water to the atomizing nozzle 6 at the other end of the connecting plate 5. The atomizing nozzle 6 converts the water into water mist to spray the dust around the conveying device 2. At the same time, the angle adjustment mechanism at one end of the fixing plate 3 drives the connecting plate 5 to rotate. The connecting plate 5 drives the atomizing nozzle 6 to change the spraying direction to achieve dust coverage in different areas. During disassembly, the fixing mechanism releases the constraint on the fixing plate 3, and the fixing plate 3 and the associated water pump device 4, atomizing nozzle 6 and other components can be removed from the mounting base 1.

[0031] More specifically, when installing the fixing plate 3, the positioning block 17 at the bottom of the fixing plate 3 is aligned with the slots at both ends of the top of the mounting base 1 and inserted to initially fix the position of the fixing plate 3. Then, the connecting screw 21 in the slide groove of the support plate 18 is rotated. The second slider 22 on the outside of the connecting screw 21 slides along the slide groove of the support plate 18 due to the threaded engagement. The top of the second slider 22 drives the clamping plate 19 to move synchronously. The first locking block 20 at the opposite end of the clamping plate 19 gradually approaches the reserved hole at one end of the fixing plate 3 and finally locks into the reserved hole. Through the double locking of the positioning block 17 with the slot and the first locking block 20 with the reserved hole, the fixing plate 3 is firmly fixed on the mounting base 1.

[0032] Please see Figure 1 and Figure 4 As one embodiment of the angle adjustment mechanism: the angle adjustment mechanism includes four sets of support rods 8, two sets of fixed plates 3 are provided with connecting blocks 9 at the top of opposite ends, two sets of connecting blocks 9 are provided with first hinge seats 10 on the front and rear sides of opposite ends, one end of two sets of connecting plates 5 is hinged to the corresponding two sets of first hinge seats 10, one end of two sets of fixed plates 3 is provided with a driving component at the bottom of opposite ends, and a sliding plate 11 is slidably provided on the bottom of opposite ends of two sets of fixed plates 3 through the driving component, two sets of support rods 8 are provided with second hinge seats 12 at both ends, one end of two sets of sliding plates 11 is hinged to one end of support rod 8 on the front and rear sides of opposite ends through the second hinge seats 12, and one end of two sets of connecting plates 5 is hinged to the other end of support rod 8 through the second hinge seats 12.

[0033] Specifically, the drive assembly at the bottom of one end of the fixed plate 3 drives the slide plate 11 to slide. The front and rear sides of the slide plate 11 at one end pull one end of the support rod 8 to move through the second hinge seat 12. The other end of the support rod 8 pushes the bottom of one end of the connecting plate 5 to rotate through the second hinge seat 12. At the same time, the top of one end of the connecting plate 5 is hinged to the first hinge seat 10 of the connecting block 9, forming a rotation structure with the first hinge seat 10 as the fulcrum, so that the connecting plate 5 drives the atomizing nozzle 6 to rotate up or down, thereby adjusting the spray angle.

[0034] Please refer to Figures 2-4 As a further embodiment of the angle adjustment mechanism: the drive assembly includes two sets of drive motors 14, and each of the two sets of fixed plates 3 has a sliding groove at one end of its bottom. A reciprocating screw 15 is rotatably arranged in the sliding groove of the two sets of fixed plates 3, and the drive motors 14 are arranged at the top of the two sets of fixed plates 3. The bottom output ends of the two sets of drive motors 14 pass through the fixed plates 3 and are connected to the top of the reciprocating screw 15. The outer side of the reciprocating screw 15 is threaded with a first slider 16, and the outer side of the first slider 16 is slidably connected to the sliding groove of the fixed plate 3. The opposite ends of the two sets of first sliders 16 are respectively connected to one end of a set of sliding plates 11.

[0035] Specifically, when the drive slide plate 11 slides, the drive motor 14 at the top of the fixed plate 3 starts, and its bottom output end passes through the fixed plate 3 and connects to the reciprocating screw 15 in the slide groove, driving the reciprocating screw 15 to rotate. The first slider 16 on the outside of the reciprocating screw 15 slides up and down along the slide groove of the fixed plate 3 due to the threaded engagement. The first slider 16 drives the slide plate 11 to move synchronously at one end. The slide plate 11 pushes the connecting plate 5 to rotate through the support rod 8, thereby realizing the angle adjustment of the atomizing nozzle 6.

[0036] In summary, the overall equipment is in use (or running):

[0037] During installation, the worker moves the two sets of fixing plates 3 using the handles 24 on the mounting bracket 23, aligns the positioning blocks 17 at the bottom of the two sets of fixing plates 3 with the slots at both ends of the top of the mounting base 1 and inserts them. The worker then rotates the rotating handle 13 on the support plate 18, and the connecting screw 21 drives the second slider 22 to slide along the slide groove of the support plate 18. The clamping plate 19 at the top of the second slider 22 moves synchronously, so that the first locking block 20 on the clamping plate 19 is inserted into the reserved hole of the fixing plate 3, thus completing the fixing.

[0038] During spraying, the water pump device 4 on the fixed plate 3 is started, and the four sets of conveying hoses 7 deliver water to the atomizing nozzles 6 at the end of the connecting plate 5. The atomizing nozzles 6 spray out atomized water. At the same time, the drive motor 14 at the top of the fixed plate 3 drives the reciprocating screw 15 to rotate, and the first slider 16 slides along the slide groove of the fixed plate 3, driving the slide plate 11 to move. The slide plate 11 pulls the support rod 8 through the second hinge seat 12. The other end of the support rod 8 pushes the connecting plate 5 to rotate with the first hinge seat 10 of the connecting block 9 as the fulcrum, so that the atomizing nozzle 6 rotates continuously during the spraying process, realizing multi-angle coverage of the dust area around the conveying device 2.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
