Description

Technical Field

[0001] The invention belongs to the technical field of coal mine dust reduction, and in particular relates to a long-range magnetized water mist dust collector for underground coal mine mining. Background Art

[0002] During underground coal mining, dust is generated primarily by coal seam crushing, shearer cutting, roadheader cutting, coal falling at transfer points, and dust generated during transportation. This dust poses a serious threat to miners' health, causing occupational diseases like pneumoconiosis, and also affects visibility underground, reducing operational efficiency and increasing the risk of accidents.

[0003] In the prior art, Chinese patent publication number CN219942246U proposes a long-range magnetized water mist dust collector for underground coal mining. The device primarily comprises a water tank, a water pipe, a magnetizing tank, a water pump, an atomizer, a dust collection cylinder, a pressure regulator, a water inlet pipe, and an atomizing nozzle. The device, which uses universal wheels to maneuver to a designated position, begins dust removal. Water from the water tank flows through the water pipe into the magnetizing tank, where it is transformed into magnetized water by the magnetic lines of force between the south and north poles of the magnets. The water pump then activates, sending the magnetized water into the atomizer for atomization. The atomized water is then transferred to a shunt pipe within the dust collection cylinder. A pressure regulator in the water inlet pipe increases the water pressure, prolonging the atomized water's airborne drift time and increasing its travel distance. Simultaneously, a motor drives the fan, further increasing the spray distance of the water mist.

[0004] Existing atomizing nozzles mainly include pressure atomizing nozzles, pneumatic atomizing nozzles, and rotary atomizing nozzles. Pneumatic atomizing nozzles, also called air atomizing nozzles, rely on the mixing of compressed air and liquid, and utilize the speed difference between the gas and liquid, the impact force, and the shear force to break the liquid into droplets. According to the gas-liquid mixing method, it can be divided into internal mixing type and external mixing type. Internal mixing pneumatic atomizing nozzles achieve gas-liquid mixing inside the nozzle, which has a better atomization effect, but has certain requirements for the viscosity and impurities of the liquid; external mixing pneumatic atomizing nozzles mix gas and liquid outside the nozzle, which is more adaptable and can handle liquids containing impurities and high-viscosity liquids. The droplets formed by pneumatic atomizing nozzles are small in size and can combine well with dust particles, making them suitable for complex dust reduction environments. The air inlet end of the air atomizing nozzle is connected to the air pump mechanism, which includes a compression component for gas compression. The compression component includes an impeller and a diffuser, that is, an impeller-type air compressor. Through the rotation of the impeller, the compression component pressurizes the gas, thereby increasing the atomization effect of the atomizing nozzle.

[0005] Existing dust suppression devices are large and rely solely on universal wheels for mobility. In actual underground coal mine environments, where tunnels are often narrow, the ground is uneven, and there is a lot of debris, universal wheels can be difficult to steer and maneuver smoothly. Furthermore, conditions such as the location of dust sources, dust concentration, and tunnel interface dimensions vary significantly across different mining areas. These devices are not well adapted to operating areas with unusual shapes or confined spaces, resulting in poor dust removal effectiveness. Summary of the Invention

[0006] The purpose of the present invention is to provide a long-range magnetized water mist dust collector for coal mine mining, which can better adapt to dust reduction operations in spaces of different sizes.

[0007] The long-range magnetized water mist dust collector for underground coal mining includes a dust reduction mechanism, which includes an atomizing nozzle. The atomizing nozzle is an air atomizing nozzle. The liquid inlet end of the atomizing nozzle is connected to a magnetized water pump mechanism that magnetizes the liquid and sends it into the magnetized water pump mechanism. The air inlet end of the atomizing nozzle is connected to an air pump mechanism. The dust reduction mechanism also includes a first shell for mounting the atomizing nozzle and having a vertical columnar structure. The magnetized water pump mechanism includes a third housing in a vertical columnar structure. The upper end of the third housing is detachably connected to the first housing. The third housing is provided with an impeller booster assembly for liquid pressurization and a magnetizer for liquid magnetization, which are arranged in sequence from top to bottom. The liquid is magnetized and pressurized by the magnetizer and then fed into the liquid inlet of the atomizing nozzle. The power input end of the impeller booster assembly is connected to the power output mechanism. The power output mechanism includes a fourth housing fixed to the bottom of the third housing and having a vertical columnar structure. The upper end of the fourth housing is connected to the third housing, and the lower end of the fourth housing is connected to the upper end of the sixth housing. A motor is installed in the fourth housing. The motor is arranged with two shafts, one above and one below. The shaft on the upper side is connected to the impeller of the impeller supercharger assembly, and the shaft on the lower side is connected to the air pump mechanism. The third housing is equipped with a liquid inlet pipe for supplying water between its inner wall and the motor. The air pump mechanism includes a sixth housing, in which an impeller compression assembly is installed. The impeller of the impeller compression assembly is connected to the rotating shaft of the motor. The gas entering the sixth housing is compressed by the impeller compression assembly and then sent to the air inlet end of the atomizing nozzle.

[0008] Start the motor, the impeller compression assembly pressurizes the gas entering the sixth shell and then sends it to the atomizing nozzle. At the same time, the water entering the fourth shell from the liquid inlet pipe goes up into the third shell. The impeller pressurizing assembly pressurizes the water in the third shell, and then magnetizes it and sends it to the atomizing nozzle. The atomizing nozzle atomizes the liquid and sprays it out. The pressurized water and gas can increase the range and atomization effect of the atomizing nozzle. The magnet makes the water atomization effect good and the dust reduction effect good. The first shell, the third shell, the fourth shell and the fourth shell are arranged vertically from top to bottom. The six shells make the entire dust collector have a columnar structure, which is convenient for transportation after being laid flat in a narrow space. The motor drives the impeller booster assembly and the impeller compression assembly to rotate at the same time, thereby making the integrated volume of the columnar structure smaller and reducing the occupied space. The liquid entering from the liquid inlet pipe passes through the space between the inner wall of the fourth shell and the motor and then is sent to the impeller booster assembly, which can cool the motor and extend the service life of the motor; the detachable first shell can remove the dust reduction mechanism, which is convenient for removal and placement in the desired position, making it more flexible to use.

[0009] Furthermore, the sixth shell is equipped with a plurality of supporting and moving mechanisms for supporting and moving, and the supporting and moving mechanisms include inclined supporting feet, the lower ends of the supporting feet are equipped with freely rotatable wheels, and the upper ends of the supporting feet are rotatably connected to the sixth shell, and a limit block with a "C"-shaped structure is fixed on the sixth shell at the rotating connection, which is used to limit the up and down swinging angle of the lower end of the supporting foot, and a guide rail with an arc-shaped structure is fixed at the notch of the limit block, and an arc-shaped groove is provided on the supporting foot corresponding to the guide rail, and the guide rail is located in the arc-shaped groove. A reset spring is installed on the guide rail in the arc-shaped groove. When the reset spring is in a free state, the supporting foot fits into the lower end of the notch of the limit block.

[0010] The supporting feet can support and move the dust collector. When placed vertically, the first shell, the third shell, the fourth shell and the sixth shell press down the supporting feet, and the lower end of the supporting feet swings upward. Under the action of the elastic force of the return spring, the supporting feet generate a downward force to support and also play a shock-absorbing role.

[0011] Furthermore, the impeller of the impeller compression assembly is connected to the motor through a second rotating shaft, and a first bevel gear is installed on the second rotating shaft between the impeller compression assembly and the motor. An anchoring assembly is provided on the left side wall of the fourth shell, and the anchoring assembly includes a fifth shell hinged on the fourth shell, and the left end of the fifth shell can swing back and forth. A second bevel gear meshing with the first bevel gear is installed in the fifth shell, and a sleeve is vertically fixed in the second bevel gear. A spiral anchor rod threadedly engaged with the second bevel gear is provided in the sleeve. The motor drives the first bevel gear to rotate, and then drives the second bevel gear to rotate. The lower end of the spiral anchor rod is inserted downward into the ground, the left end of the fifth shell swings, and the second bevel gear is separated from the first bevel gear.

[0012] After reaching the desired position, the motor is started to drive the first bevel gear to rotate, and then the second bevel gear is driven to rotate. The lower end of the spiral anchor is inserted downward into the ground. After it is fixed, the motor is turned off, and the fourth shell hinged to the right end of the fifth shell is swung to separate the second bevel gear from the first bevel gear and lock the fifth shell to fix the dust collector. With the support of the supporting mobile mechanism, the dust collector is more stable during use, and the motor is used to drive the anchor assembly to work, which is convenient, fast and simple in structure.

[0013] Furthermore, an output mechanism is provided between the magnetized water pump mechanism and the dust reduction mechanism, and the output mechanism includes a second shell of a vertical columnar structure, the lower end of the second shell is connected to the upper end of the third shell, and is connected and communicated with the third shell, the top of the second shell is detachably connected to the first shell, and is equipped with a liquid outlet head for outputting the liquid therein to the atomizing nozzle, and an air outlet head for outputting gas to the atomizing nozzle is installed on the top of the second shell on one side of the liquid outlet head, and the air inlet end of the air outlet head is connected and communicated with the output end of the air pump mechanism.

[0014] After removing the dust reduction mechanism, the extension pipeline can be connected through the air outlet head and the liquid outlet head, making it convenient to remove the dust reduction mechanism and install it in other locations for use, with a wider range of uses.

[0015] Furthermore, a connecting seat is connected to the bottom of the first shell, and the connecting seat includes a fixed disk connected to the first shell, and a rotating shaft is fixed in the fixed disk in the front-to-back direction. A plurality of support components distributed front-to-back are provided between the fixed disk and the second shell, and the support component includes a vertically arranged left support block and a right support block, and the upper ends of the left support block and the right support block are hinged to the rotating shaft, and the lower end of the left support block can swing to the left, and the lower end of the right support block can swing to the right. Blocks are provided on the fixed disks on the left and right sides of the rotating shaft, and the left support block is engaged with the block on the left after swinging to the left, and the right support block is engaged with the block on the right after swinging to the right. The lower ends of the left support block and the right support block can be detachably connected to the top of the second shell.

[0016] When the dust reduction mechanism needs to be removed for use, the lower ends of the left support block and the right support block are removed from the second shell, the left support block is swung to the left, and the right support block is swung to the right. The lower ends of the left support block and the right support block are opened and used as support legs, which is easy to use.

[0017] Furthermore, the card block has a "T"-shaped structure, and the bottom of its horizontal part corresponds to the support assembly and is provided with a "C"-shaped card slot.

[0018] The "C"-shaped card slot and cylindrical card block facilitate the lower end of the left support block to swing to the left and the lower end of the right support block to swing to the right for insertion and removal.

[0019] Furthermore, an articulated support is installed on the top of the second shell, and an articulated shaft is provided on the articulated support in the front-to-back direction. The lower ends of the left support block and the right support block are detachably engaged inward on the articulated shaft, and a flexible sleeve for limiting the support assembly is detachably connected between the connecting seat and the articulated support.

[0020] The lower end of the support assembly is hinged to the hinged support and can swing left and right. After swinging, the flexible sleeve limits the angle of the dust suppression mechanism, making it easy to adjust the angle of the dust suppression mechanism.

[0023] Furthermore, a mounting block is fixed on the first shell corresponding to the adjustment block, a vertical adjustment hole is opened on the mounting block, and a first fixing member for locking the adjustment block is installed in the adjustment hole.

[0024] Furthermore, the dust reduction mechanism includes a plurality of first shells in sequence from top to bottom, and two upper and lower adjacent first shells are detachably connected and are fixed after being rotated by a second fixing member.

[0025] The plurality of first shells can flexibly increase or decrease the number of installed atomizing nozzles, and has a wider scope of application.

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. The overall columnar structure makes full use of the space in the vertical direction and reduces the equipment's horizontal footprint. In environments with limited space, such as underground coal mine tunnels, it can be more conveniently placed and moved, avoiding collisions with tunnel walls or other equipment due to the equipment's large size. 2. The motor drives the impeller booster assembly and the impeller compression assembly to rotate at the same time, thereby making the integrated volume of the columnar structure smaller and reducing the space occupied. The water entering from the liquid inlet pipe passes through the space between the inner wall of the fourth shell and the motor before being sent to the impeller booster assembly, which can cool the motor and extend the service life of the motor. 3. The dust suppression mechanism can be removed and placed separately, which increases the flexibility of using the dust collector. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shaft and the mounting holes at the rear end of the atomizing nozzle 1.2 are hingedly connected to each other and are in rotational engagement. The front end of the atomizing nozzle 1.2 can swing up and down within the mounting slot 1.3. Figure 5 As shown, a long vertical adjustment hole 1.9 is provided on the first housing 1.1 at the bottom of the mounting groove 1.3. Figure 1 and Figure 5As shown, a vertical rectangular through hole is provided on the rear side wall of the first housing 1.1, and a rectangular mounting block 1.6 is installed at the rectangular through hole. Figure 7 As shown, the mounting block 1.6 is provided with a slide groove communicating with the inside and outside, and the adjusting block 1.4 is placed in the slide groove, and the adjusting block 1.4 is matched with the slide groove in an up-down sliding manner.

[0042] like Figure 8 and Figure 9 As shown, the inner end of the adjustment block 1.4 is located in the first shell 1.1 and has a rectangular notch. A cylindrical limit block is provided on each side of the notch. The front end of the atomizing nozzle 1.2 is the nozzle end, and the rear end is the end. The end is obliquely connected to the long strip of adjustment plate 1.8. The adjustment plate 1.8 has a slide groove on both sides. The cylindrical limit block of the adjustment block 1.4 is embedded in the slide groove to achieve connection and limitation. The left wall of the mounting block 1.6 is provided with a waist-shaped hole, which serves as an adjustment hole. The adjustment hole extends through the slide groove of the mounting block 1.6. The first fixing part 1.7 is installed on the adjustment hole. The first fixing part 1.7 is an eccentric cam clamping rod. Its threaded rod passes through the waist-shaped hole and is connected to the adjustment block 1.4. After the adjustment block 1.4 slides to the appropriate position, it is locked by the first fixing part 1.7.

[0043] like Figure 5 As shown, two dust suppression mechanisms 1 are connected end to end. A top cover 16 is mounted on the top of the first housing 1.1 of the upper dust suppression mechanism 1. This top cover 16 is a disc-shaped structure, with a slot at the bottom that engages with the top of the first housing 1.1. A connecting base 2 is mounted on the bottom of the lower first housing 1.1 to engage with it.

[0044] like Figure 5 and 8 As shown, the connecting base 2 includes a fixed disk 2.1, which is a circular disk structure. A buckle is provided on the top of the fixed disk 2.1 and engages with the bottom slot of the first shell 1.1; a rotating shaft 2.3 is longitudinally fixed at the center of the fixed disk 2.1, and a rectangular notch is provided on the fixed disk 2.1 on the left and right sides of the rotating shaft 2.3. A "T"-shaped structure card block 2.2 is longitudinally installed on both sides of the middle section of the rotating shaft, that is, the horizontal part of the card block 2.2 is arranged parallel to the rotating shaft 2.3, and a "C"-shaped structure card slot is provided at the bottom of the cross bar of the card block 2.2. The length of the card block 2.2 requires that its card slot is located above the notch on both sides of the rotating shaft 2.3, and a support component 3 is hinged at both ends of the rotating shaft 2.3.

[0045] like Figure 8 As shown, the support assembly 3 includes a left support block 3.1 and a right support block 3.2, both of which are rectangular blocks with a circular ring on top. The left support block 3.1 and the right support block 3.2 form a pair of support blocks. The top outer corners of each pair of support blocks are chamfered, the bottom outer corners are rounded, and the inner bottom has a semicircular notch concentric with the rounded corners. The two pairs of support blocks are hinged to the rotating shaft 2.3 via the circular rings; Figure 8 As shown, cylindrical clamping blocks are installed at the chamfers of the left and right support blocks 3.1, 3.2. A cylindrical clamping block is also fixed below the semicircular notch on the left side wall of the right support block 3.2, and a cylindrical clamping block is fixed below the semicircular notch on the right side wall of the left support block 3.1. On the front and rear outer walls of the left and right support blocks 3.1, 3.2, multiple hemispherical grooves are evenly spaced along the circumference, with the center of the semicircular notch as the axis.

[0046] like Figure 7 As shown, a fixing strip 18 is installed on the front side wall of the first shell 1.1, on the side of the mounting block 1.6, and its two ends are respectively fixed to the top cover 16 and the fixing plate 2.1, and two second fixing members 19 are installed on the fixing strip 18, corresponding to the two first shells 1.1 respectively, and the second fixing member 19 has the same structure as the first fixing member 1.7, and can be used for downward tightening to limit the rotation of the dust reduction mechanism 1.

[0047] like Figure 7 As shown, the lower part of the connecting base 2 is connected to the hinge support 4, and the hinge support 4 is installed with hinge shafts distributed in the front-to-back direction. After the left support block 3.1 and the right support block 3.2 are combined, the cylindrical clamping block on the inner side and the "C"-shaped structure of the clamping groove are interlocked with each other, and the semicircular notches of the two form a complete circular notch, which is mounted on the hinge shaft of the hinge support 4 to achieve hinge connection. Figure 1 and Figure 7 As shown, a flexible sleeve 15 is installed between the connecting seat 2 and the hinge support 4. The flexible sleeve 15 can be a bellows. A threaded hole is opened on the front side of the hinge support 4, through which a ball screw is installed. The steel ball of the ball screw cooperates with the hemispherical groove on the outer wall of the support component 3, thereby limiting the position of the connecting seat 2 after it swings along the hinge support 4. Figure 3 As shown, a through-notch is provided at the bottom of the hinged support 4 to avoid blocking the liquid outlet head 5.2 and the gas outlet head 5.3; a water pipe 13 and an air pipe 14 are connected between the liquid outlet head 5.2 and the gas outlet head 5.3 and the atomizing nozzle 1.2 to achieve communication, so that the liquid and gas are transported to the atomizing nozzle 1.2, and the tube bodies of the air pipe 14 and the water pipe 13 are clamped on the tube bundle block 1.5.

[0048] The instructions for using the above technical solution are as follows: After reaching the desired position, use the anchoring assembly 8 to anchor the device. The specific process is as follows: like Figure 7 As shown, the dust collector equipment is first moved to the work site through the supporting moving mechanism 9. Figure 3As shown, the motor 7.2 is started, and the motor 7.2 rotates the first bevel gear 7.3, driving the second bevel gear 8.2 and the sleeve 8.3 to rotate. The spiral anchor rod 8.4 is threadedly matched with the sleeve 8.3, so that the spiral anchor rod 8.4 rotates downward, and its spiral cutting edge is anchored into the bottom surface, as shown in FIG. Figure 4 As shown, the support foot 9.2 is forced to swing upward, and under the action of the reset spring 9.3, the support foot 9.2 generates a downward force to provide auxiliary support. The direction of the wheel 9.1 can be on the opposite side of the spiral anchor rod 8.4, that is, on the right side of the sixth shell 11.1, to facilitate auxiliary support. Figure 7 and Figure 8 As shown, the atomizing nozzle 1.2 can be swung out from the mounting groove 1.3 by first driving the adjusting plate 1.8 through the adjusting block 1.4. Figure 3 As shown, the rotation of the first bevel gear 7.3 driven by the motor 7.2 also drives the rotation of the first rotating shaft 6.4 and the second rotating shaft 11.5. At this time, the liquid inlet pipe 7.4 is not yet connected to water. The first rotating shaft 6.4 drives the impeller booster assembly 6.2 to generate wind force, which passes through the check valve 5.4 and the liquid outlet head 5.2 and is then sent to the atomizing nozzle 1.2 through the water pipe 13. The second rotating shaft 11.5 drives the outlet impeller 11.2, the impeller compression assembly 11.3, and the intake impeller 11.4 to rotate. The intake impeller 11.4 draws air, the impeller compression assembly 11.3 compresses the inhaled air, and the outlet impeller 11.2 discharges the air. The air is then sent to the outlet head 5.3 through the connecting pipe 12 and the air path 20, and then through the air pipe 14 to the atomizing nozzle 1.2. This process can pre-purge the air and water paths of the atomizing nozzle 1.2.

[0049] The principle of use after anchoring is completed is as follows: like Figure 6 As shown, after the screw anchor 8.4 is anchored, the motor 7.2 is turned off. Figure 6 As shown, the fourth housing 7.1 is swung along the hinge point so that the second bevel gear 8.2 and the first bevel gear 7.3 are no longer engaged and locked by the second fixing member 19. The atomizing nozzle 1.2 is adjusted to the upper and lower positions according to the use requirements by the adjustment block 1.4 and then locked by the first fixing member 1.7. If the atomizing nozzles 1.2 on the two first housings 1.1 need to be positioned in different directions, just rotate the first housing 1.1 and then fix it with the second fixing member 19. Figure 4 As shown, the liquid inlet end of the liquid inlet pipe 7.4 is connected to the water source, and the liquid enters the cavity of the fourth shell 7.1. Figure 3As shown, motor 7.2 is started, driving first shaft 6.4 and second shaft 11.5. First shaft 6.4 drives impeller booster assembly 6.2 to generate suction and boost the liquid pressure. The liquid enters the chamber of third housing 6.1 through the through-hole at the top of fourth housing 7.1. After magnetizer 6.3 magnetizes the liquid, the liquid impacts check valve 5.4, enters water pipe 13 from outlet head 5.2, and is delivered to atomizing nozzle 1.2. Second shaft 11.5 drives outlet impeller 11.2, impeller compression assembly 11.3, and intake impeller 11.4. Intake impeller 11.4 draws in air, while impeller compression assembly 11.3 compresses the air. Exit impeller 11.2 then discharges the air, which is then transported through connecting pipe 12, air path 20, outlet head 5.3, and air pipe 14 to atomizing nozzle 1.2. Finally, the gas and liquid are atomized at the atomizing nozzle 1.2 and then sprayed out, and are ejected far away through the magnetized water pump mechanism 6, thereby having a dust reduction effect on the dust.

[0050] When used in a low-profile work environment, the operating principles are as follows: like Figure 7 As shown, the dust suppression mechanism 1 can be swung through the support assembly 3 and the hinged support 4. The steel ball of the ball screw of the hinged support 4 cooperates with the hemispherical groove on the outer wall of the support assembly 3 to limit the position and reduce the height of the entire device. The flexible sleeve 15 is bent to protect the connecting base 2, support assembly 3, and hinged support 4 from the influence of the dust environment.

[0051] like Figure 8 As shown, first remove the upper end of the flexible sleeve 15, open the left support block 3.1 and the right support block 3.2, and use the cylindrical blocks at the chamfers of the left support block 3.1 and the right support block 3.2 to engage with the "C"-shaped slots on both sides of the block 2.2, thereby separating the dust reduction mechanism 1 from the hinged support 4. At this time, the left support block 3.1 and the right support block 3.2 can be used as support legs respectively, and the dust reduction mechanism 1 is placed on the bottom surface. The dust reduction mechanism 1, the water pipe 13 and the air pipe 14 connected to the liquid outlet head 5.2 and the air outlet head 5.3 are extended, and then atomization dust removal is performed.

[0052] Support legs 9.2, activated by return springs 9.3, adapt to varying terrains, keeping the equipment stable. Meanwhile, spiral anchors 8.4 can be anchored into the ground to enhance stability, overcoming the limitations of universal wheel mobility. In tight spaces, the dust suppression mechanism 1 can be swung to lower the equipment, or the water pipe 13 and air pipe 14 can be extended, separating the dust suppression mechanism 1 from the articulated support 4 and using it as a support leg for close-range dust removal, offering greater adaptability.

[0053] The position of the atomizing nozzle 1.2 can be flexibly adjusted via an adjustment block 1.4 and locked by a first fixing member 1.7. The first housing 1.1 can also be rotated to secure it via a second fixing member 19, allowing for full adjustment and precise dust removal to meet diverse dust removal needs. This is particularly effective in confined or unusually shaped work areas, effectively resolving the issue of poor dust removal effectiveness with existing technologies. After use, the atomizing nozzle 1.2 can be stored in the mounting slot 1.3, providing maximum protection from damage and preventing dust from clogging the nozzle of the atomizing nozzle 1.2 during transport.

[0054] During operation, the device drives the magnetized water pump mechanism 6 and the air pump mechanism 11 simultaneously through the motor 7.2, realizing the simultaneous operation of liquid pressurization magnetization and gas compression and transportation. This integrated design not only improves the overall efficiency, but also reduces energy loss and equipment volume. The liquid entering the liquid inlet pipe 7.4 can also cool the motor 7.2. The magnetized water is mixed with compressed air and atomized through the atomizing nozzle 1.2 to enhance the dust removal effect. The device is a columnar structure as a whole. This structure makes full use of space in the vertical direction and reduces the equipment's footprint in the horizontal direction. In an environment with limited space, such as an underground coal mine tunnel, it can be more conveniently placed and moved to avoid interference with the tunnel wall or other equipment due to the large size of the equipment.
