Description

Technical Field

[0001] This disclosure relates to the field of coal transportation technology, and in particular to a suspended sliding vibration coal press and a coal pressing work platform. Background Technology

[0002] As economic development intensifies, energy demand continues to grow. Most of my country's coal reserves are located in the western region, and transportation mainly relies on railways.

[0003] Due to differences in coal quality, some coals have high density while others are low density and lightweight. Therefore, when different types of coal are loaded onto the same type of vehicle, the lighter coal, even after being loaded to the standard volume, will significantly exceed the height limit. During transportation, a large portion of the excess coal will be blown away by airflow and scattered along the railway line. This not only seriously pollutes the surrounding environment but also causes substantial economic losses each year due to the coal blown away by airflow. Furthermore, coal dust adsorbs onto electrical equipment along the railway line. Because carbon is conductive, when coal dust accumulates to a certain level, the insulators will short-circuit and discharge, creating a significant safety hazard.

[0004] Therefore, coal companies can only reduce the tonnage loaded onto wagons to avoid the impact of exceeding height limits. However, railway transportation stipulates that freight charges are still charged based on the standard volume of the wagon regardless of whether the tonnage of the loaded goods meets the measurement standards, resulting in significant economic losses for coal companies every year. Summary of the Invention

The hinge point is located on the other side of the hinge point between the rocker arm and the walking mechanism. The second telescopic cylinder is fixedly mounted on the traveling mechanism and configured to drive the rocker arm to rotate around the hinge point with the traveling mechanism, so that the first link and the second link pull the corresponding hook to hook the corresponding lifting lug, or disengage from the lifting lug.

[0012] In one embodiment of this disclosure, the suspended sliding vibratory coal press further includes: A first damping mechanism is disposed between the vibration platform and the eccentric drive mechanism and is configured to absorb radial vibrations generated by the eccentric drive mechanism. A second damping mechanism is disposed between the vibration platform and the eccentric drive mechanism and is configured to absorb axial vibrations generated by the eccentric drive mechanism.

[0013] In one embodiment of this disclosure, the first shock absorption mechanism includes: The first connecting sleeve is fixedly connected to the vibration platform and is coaxially arranged with the output shaft of the eccentric drive mechanism; The second connecting sleeve is coaxially arranged with the motor output shaft of the eccentric drive mechanism and has a radial gap with the first connecting sleeve.

The pressure wheel is located behind the eccentric vibrating wheel. A piston cylinder, the cylinder body of which is fixedly mounted on the vibration platform, the piston rod of which is fixedly connected to the rotating shaft and located between the two pressure rollers; and, The pressure roller is configured to descend to contact the coal powder under the action of the piston cylinder and smooth out the coal powder overflowing during the compaction process of the eccentric vibrating roller under the action of friction.

The receiving platform and frame are fixedly connected, and the eccentric vibrating wheel is indirectly fixed to the frame. The transport equipment starts and moves away from the frame. The eccentric drive mechanism generates vibration waves, which are transmitted to the coal dust, causing a rearrangement of the coal's bulk density. Smaller coal particles enter the gaps between larger coal particles, and excess coal at the top of the carriage sinks, compacting the coal dust within the transport equipment. This increases the coal transport capacity and prevents the coal dust at the top from being blown away by airflow during transport, reducing environmental pollution and economic losses. Furthermore, when transported by rail, it also prevents safety accidents caused by coal dust adhering to electrical equipment along the railway line.

[0031] To address the problem of coal dust being blown away by airflow from the top of transport equipment, this disclosure provides a suspended sliding vibratory coal press and a coal pressing work platform. For ease of understanding, please refer to the following... Figures 1 to 12 The specific structure and working principle of the suspended sliding vibration coal press and the coal pressing work platform disclosed herein will be described in detail with reference to the embodiments.

[0032] Reference Figure 1 , Figure 2 The suspended sliding vibratory coal compactor includes a frame 1, a traveling mechanism 2, a vibrating platform 3, and an eccentric vibrating wheel 5. The frame 1 has a passage for the transport equipment to pass through and is provided with a suspended track 11. The traveling mechanism 2 is mounted on the frame 1 and is configured to travel along the suspended track 11 to or away from the transport equipment. The vibrating platform 3 is detachably suspended on the traveling mechanism 2 and is connected to or detached from the traveling mechanism 2 under the action of a first drive mechanism. The eccentric vibrating wheel 5 is rotatably mounted on the vibrating platform 3 and is configured to generate vibration waves under the action of the eccentric drive mechanism 51 to compact the coal on top of the transport equipment.

[0033] Specifically, frame 1 is a steel portal frame with a two-layer structure. The right side of the lower structure has a passageway for transport equipment. When the transport equipment is a freight truck, the ground in the passageway serves as the working surface for the truck. When the transport equipment is a freight train, the ground in the passageway has a track for the transport equipment. The left side of the lower structure is the parking position of the traveling mechanism 2 when the suspended sliding vibratory coal press is not in operation. The upper structure is equipped with a suspended track 11, which extends perpendicular to the traveling direction of the transport equipment.

[0034] The traveling mechanism 2 can travel above the transport equipment via the suspended track 11. The suspended track 11 is an I-shaped track. The traveling mechanism 2 includes a base 22, a driving wheel, and a driven wheel. The driving wheel and driven wheel are respectively disposed on the horizontal end faces on both sides of the I-shaped track and are rotatably mounted on the base 22 of the traveling mechanism 2 via rotating bearings. The traveling mechanism 2 also includes a motor, which is fixedly mounted on the base 22. The drive shaft of the motor is coaxially connected to the driving wheel and drives the driving wheel to travel on the suspended track 11. The driving wheel can be positioned inside or outside the suspended track 11. Similarly, the position of the motor can be adjusted accordingly based on the position of the driving wheel.

[0035] Reference Figure 3 , Figure 4 The vibrating platform 3 is detachably suspended from the base 22 of the traveling mechanism 2. When the suspended sliding vibrating coal press starts working, the motor of the traveling mechanism 2 is energized in the forward direction, driving the drive wheel and driven wheel to travel on the suspended track 11, thereby driving the vibrating platform 3 from the left-side parking position to above the transport equipment. When the suspended sliding vibrating coal press stops working, the motor of the traveling mechanism 2 is energized in the reverse direction, driving the drive wheel and driven wheel to travel in the reverse direction on the suspended track 11, thereby driving the vibrating platform 3 from above the transport equipment to the left-side parking position.

[0036] Reference Figure 2 , Figure 4 The first drive mechanism drives the vibration platform 3 to connect or disconnect from the traveling mechanism 2. In detail, in one embodiment, the suspended sliding vibration coal press also includes four pairs of lifting lugs 31 and hooks 21; wherein, the lifting lugs 31 are fixedly mounted on the vibration platform 3, and the hooks 21 are rotatably mounted on the traveling mechanism 2 and are configured to hook or disconnect from the corresponding lifting lugs 31 under the action of the first drive mechanism.

[0037] Specifically, the hook 21 is rotatably mounted on the traveling mechanism 2 via a hinge support. When the hook 21 is vertically suspended below the traveling mechanism 2 and is in the working position of hooking the corresponding lifting lug 31, the first drive mechanism can drive the hook 21 to rotate relative to the traveling mechanism 2 in a first direction and disengage from the corresponding lifting lug 31. Conversely, the first drive mechanism can also drive the hook 21 to rotate relative to the traveling mechanism 2 in the opposite first direction until the hook 21 hooks the corresponding lifting lug 31, thereby achieving the fixation and disengagement of the vibration platform 3 from the traveling mechanism 2.

[0038] Reference Figure 4In one embodiment, the first drive mechanism includes a rocker arm 41, a first connecting rod 42, a second connecting rod 43, and a second telescopic cylinder 44. The rocker arm 41 is hinged to the base 22 of the traveling mechanism 2. One end of the first connecting rod 42 is hinged to a hook 21, and the other end is hinged to the rocker arm 41. The hinge point is located on one side of the hinge point between the rocker arm 41 and the traveling mechanism 2. One end of the second connecting rod 43 is hinged to another hook 21, and the other end is hinged to the rocker arm 41. The hinge point is located on the other side of the hinge point between the rocker arm 41 and the traveling mechanism 2. The second telescopic cylinder 44 is fixedly mounted on the traveling mechanism 2 and configured to drive the rocker arm 41 to rotate around the hinge point with the traveling mechanism 2, so that the first connecting rod 42 and the second connecting rod 43 pull the corresponding hook 21 to hook the corresponding lifting lug 31, or disengage from the lifting lug 31.

[0039] Specifically, a support 45 is provided below the walking mechanism 2, and the rocker arm 41 is hinged to the support 45. One end of the first connecting rod 42 is hinged to a hook 21, and the other end is hinged to the rocker arm 41. The hinge point is located on one side of the hinge point between the rocker arm 41 and the walking mechanism 2. When the rocker arm 41 rotates, it pulls the first connecting rod 42, which in turn pulls the hook 21 to rotate relative to the walking mechanism 2. One end of the second connecting rod 43 is hinged to another hook 21, and the other end is hinged to the rocker arm 41. The hinge point is located on the other side of the hinge point between the rocker arm 41 and the walking mechanism 2. When the rocker arm 41 rotates, it pulls the second connecting rod 43, which in turn pulls the other hook 21 to rotate relative to the walking mechanism 2. The second telescopic cylinder 44 is fixedly mounted on the base 22 of the walking mechanism 2, driving the rocker arm 41 to rotate around the hinge point with the walking mechanism 2. When the rocker arm 41 rotates, the first connecting rod 42 and the second connecting rod 43 move closer or further away, thereby controlling the hook 21 to rotate, so that the hook 21 is disengaged from the lifting lug 31, thus realizing the fixation and disengagement of the vibration platform 3 from the walking mechanism 2.

[0040] The eccentric vibrating wheel 5 is rotatably mounted on the vibrating platform 3. The eccentric vibrating wheel 5 is equipped with an eccentric drive mechanism 51, which can generate vibration waves to impact and compact the coal powder in the transport equipment. The coal powder is specifically the high-density coal powder in the freight train.

[0041] For details, refer to Figure 10 , Figure 11The eccentric drive mechanism 51 includes a spindle 511 rotatably mounted inside the eccentric vibrating wheel 5. Specifically, bearing seats are fixedly mounted at both ends of the eccentric vibrating wheel 5, and the two ends of the spindle 511 are rotatably mounted on the bearing seats via corresponding rotating bearings. The spindle 511 is driven to rotate by a hydraulic motor. Two fixed eccentric blocks 512 and a movable eccentric block 513 located between the two fixed eccentric blocks 512 are spaced apart on the spindle 511. The two fixed eccentric blocks 512 are connected by a stop pin 514, and the stop pin 514 is configured such that when the two fixed eccentric blocks 512 rotate with the spindle 511 and come into contact with the movable eccentric block 513, they push the movable eccentric block 513 to rotate. As the fixed eccentric blocks 512 and the movable eccentric block 513 generate centrifugal force during rotation, the eccentric vibrating wheel 5 vibrates.

[0042] Furthermore, when the two fixed eccentric blocks 512 rotate with the spindle 511, the stop pin 514 contacts the movable eccentric block 513, pushing the movable eccentric block 513 to rotate by a preset angle. This ensures the movable eccentric block 513 rotates synchronously with the two fixed eccentric blocks 512, achieving the superposition of static eccentricities. When the rotation direction of the hydraulic motor is changed, the spindle 511, along with the two fixed eccentric blocks 512 and the stop pin 514, rotates 180° around the axis of the spindle 511. The stop pin 514 then strikes the movable eccentric block 513, pushing it to rotate in the same direction as the two fixed eccentric blocks 512 with a 180° phase difference, achieving the subtraction of static eccentricities. By changing the rotation direction of the spindle 511, the amplitude of the eccentric drive mechanism 51 can be adjusted.

[0043] Furthermore, by Figure 7 As can be seen, the eccentric vibrating wheel 5 of this disclosure is a long cylindrical wheel. In order to ensure that the eccentric vibrating wheel 5 is subjected to a relatively uniform vibration wave, in one embodiment, the coal press of this disclosure includes two eccentric drive mechanisms 51, and the two eccentric drive mechanisms 51 are respectively disposed at both ends of the axis of the eccentric vibrating wheel 5. The spindles 511 of the two eccentric drive mechanisms 51 are fixedly connected through a transmission connecting shaft. One end of the spindle 511 is rotatably mounted on a bearing seat through a corresponding rotating bearing, and the other end is fixedly connected to the transmission connecting shaft so that the two spindles 511 share the same hydraulic motor drive.

[0044] The receiving platform is set on the frame 1 and is configured to receive the vibration platform 3 after the vibration platform 3 and the traveling mechanism 2 are separated, and to allow the eccentric vibration wheel 5 to protrude from below.

[0045] Specifically, the receiving platform is a rectangular frame structure composed of two long crossbeams and two short crossbeams, which is set on the columns on the front and rear sides of the frame 1. The vibration platform 3 can be separated from the walking mechanism 2 under the action of the first drive mechanism. After the vibration platform 3 is separated from the walking mechanism 2, the crossbeams of the receiving platform support the vibration platform 3 and are fixed to the vibration platform 3. The hollow part in the middle allows the eccentric vibration wheel 5 to protrude from the bottom of the receiving platform.

[0046] Work process: The transport equipment enters the passage and stops. The traveling mechanism 2, carrying the vibrating platform 3 and the eccentric vibrating wheel 5, travels along the suspended track 11 from its parking position to above the transport equipment. The first drive mechanism drives the vibrating platform 3 to separate from the traveling mechanism 2. The receiving platform receives the vibrating platform 3 and causes the eccentric vibrating wheel 5 to protrude from below, making contact between the eccentric vibrating wheel 5 and the coal powder inside the transport equipment. The eccentric drive mechanism 51 is activated, causing the eccentric vibrating wheel 5 to generate vibration waves, which compact the coal powder inside the transport equipment. The receiving platform and the frame 1 are fixedly connected, and the eccentric vibrating wheel 5 is indirectly fixed to the frame 1. The transport equipment starts and moves away from the frame 1. The friction between the coal powder and the eccentric vibrating wheel 5 pushes the eccentric vibrating wheel 5 to rotate relative to the vibrating platform 3, thereby compacting the coal powder inside the entire transport equipment.

[0047] Obviously, the suspended sliding vibratory coal compactor disclosed herein is equipped with an eccentric vibrating wheel 5, which is only carried by the traveling mechanism 2 to the top of the transport equipment when needed. It then detaches from the traveling mechanism 2 and falls into the transport equipment car containing pulverized coal. The high-frequency vibration waves generated by the internal eccentric drive mechanism 51 repeatedly strike the pulverized coal, causing a rearrangement of the coal's bulk density. Smaller pulverized coal particles enter the gaps between larger coal particles, and excess coal at the top of the car sinks, compacting the pulverized coal within the transport equipment. This increases the coal transport capacity and prevents the pulverized coal at the top from being blown away by airflow during transport, reducing environmental pollution and economic losses. Furthermore, when transported by rail, it also prevents safety accidents caused by pulverized coal adhering to electrical equipment along the railway line.

[0048] Reference Figure 2 In one embodiment, the receiving platform is mounted on the frame in a liftable manner.

[0049] When the actual height of the pulverized coal inside the conveying equipment is high, the receiving platform lowers the vibrating platform 3 relative to the conveying equipment, thereby lowering the eccentric vibrating wheel 5. When the actual height of the pulverized coal inside the conveying equipment is low, the receiving platform raises the vibrating platform 3 relative to the conveying equipment, thereby raising the eccentric vibrating wheel 5. After the vibrating platform 3 is fixed to the receiving platform, when the conveying equipment passes through the channel at a constant speed, the eccentric vibrating wheel 5 can rotate relative to the vibrating platform 3 by means of friction with the pulverized coal, thus compacting the pulverized coal. By setting up the receiving platform, the eccentric vibrating wheel 5 can rise and fall with the receiving platform, allowing it to adapt to pulverized coal at different heights and complete the work of compacting the pulverized coal.

[0050] In one embodiment, refer to Figure 6 The receiving platform includes a first telescopic cylinder 61, a platform body 62, a first rope 63, and a second rope 64. The cylinder body of the first telescopic cylinder 61 is fixedly mounted on the frame 1. The platform body 62 is configured to receive and fix the vibration platform 3 after it is disengaged from the walking mechanism 2. One end of the first rope 63 is fixedly connected to the telescopic rod of the first telescopic cylinder 61, and the other end is tensioned by a first fixed pulley group mounted on the frame 1 and fixedly connected to the front end of the platform body 62. One end of the second rope 64 is fixedly connected to the telescopic rod of the first telescopic cylinder 61, and the other end is tensioned by a second fixed pulley group mounted on the frame 1 and fixedly connected to the rear end of the platform body 62.

[0051] Specifically, the first telescopic cylinder 61 can be a hydraulic cylinder, with the cylinder body fixedly connected to the side wall of the column of the frame 1, and the telescopic rod can extend and retract in the vertical direction.

[0052] When the height of the eccentric vibrating wheel 5 needs to be lowered according to the actual height of the coal powder in the transport equipment, the first telescopic cylinder 61 is driven so that its telescopic rod extends out of the cylinder body. Under its own weight, the platform body 62, which is fixed to the free ends of the first rope 63 and the second rope 64, descends until the vibrating platform 3 on it carries the eccentric vibrating wheel 5 to the preset position. When the eccentric vibrating wheel 5 is in the preset position, it compacts the coal powder in the transport equipment under the action of the vibration wave generated by the eccentric drive mechanism 51.

[0053] Conversely, when the height of the eccentric vibrating wheel 5 needs to be increased according to the actual height of the coal powder inside the transport equipment, the first telescopic cylinder 61 is driven to retract its telescopic rod into the cylinder. The telescopic rod overcomes the self-weight of the platform body and pulls the platform body 62 up through the first rope 63 and the second rope 64 until the vibrating platform 3 on it carries the eccentric vibrating wheel 5 to the preset position. When the eccentric vibrating wheel 5 is in the preset position, it compacts the coal on the top of the transport equipment under the action of the vibration wave generated by the eccentric drive mechanism 51.

[0054] It is understandable that the aforementioned telescopic cylinders and ropes are installed on both the left and right sides of the platform body 62. With this configuration, the first telescopic cylinder 61 can control the lifting or lowering of the vibrating platform 3, which can be applied to coal powder at different heights in the compaction and transportation equipment, thereby improving the applicability of the suspended sliding vibrating coal compactor.

[0055] In another embodiment, the receiving platform is also provided with a connecting plate 65, one end of the first rope 63 and the second rope 64 are fixedly connected to the connecting plate 65, and the telescopic rod is fixedly connected to the connecting plate 65, so as to realize the indirect connection between the telescopic rod and the first rope 63 and the second rope 64, and prevent the telescopic rod from being too small to be easily connected.

[0056] In addition, connecting blocks 66 are provided at the front and rear ends of the platform body 62 respectively. The front connecting block 66 is connected to the end of the first rope 63, and the rear connecting block 66 is connected to the end of the second rope 64. A pulley is also provided on the connecting block 66, and a guide rail that engages with the pulley is provided on the frame 1.

[0057] When the telescopic rod of the first telescopic cylinder 61 extends out of the cylinder body, the connecting block 66 and the platform body 62 descend vertically along the frame 1 under their own weight; when the telescopic rod of the first telescopic cylinder 61 retracts into the cylinder body, the first rope 63 and the second rope 64 pull the connecting block and the platform body 62 upward vertically along the frame 1. Because the pulley engages with the guide rail of the frame 1, the platform body 62 will not rotate or sway during lifting and lowering, ensuring safety during coal pressing operations.

[0058] See Figure 2 , Figure 5 In one embodiment, the vibration platform 3 and the platform body 62 are pre-positioned by matching positioning pins 7 and positioning holes 8, and the positioning pins 7 are provided with slots; the suspended sliding vibration coal press also includes an insert plate 65 and a driving element for driving the insert plate 65 to insert into or disengage from the slot; one of the positioning pins 7 and the positioning holes 8 is provided on the vibration platform 3, and the other is provided on the platform body 62.

[0059] Specifically, the vibration platform 3 is provided with four positioning pins 7, and the crossbeam of the platform body 62 is provided with four matching positioning holes 8. The protruding part of the positioning pin 7 inserted into the positioning hole 8 has a slot. The insert plate 65 and the driving element are located at the bottom of the platform body 62. The driving element can be a hydraulic cylinder.

[0060] When it is necessary to fix the vibration platform 3 and the platform body 62, the positioning pin 7 of the vibration platform 3 is inserted into the corresponding positioning hole 8 on the platform body 62, the telescopic rod of the drive element extends out from the cylinder body, and the telescopic rod pushes the insert plate 65 into the slot of the positioning pin 7, thus completing the fixation of the vibration platform 3 and the platform body 62.

[0061] When it is necessary for the vibration platform 3 to separate from the platform body 62, the telescopic rod of the drive element retracts into the cylinder, and the telescopic rod pulls the insert plate 65 out of the slot of the positioning pin 7. Then, the positioning pin 7 of the vibration platform 3 separates from the corresponding positioning hole 8 on the platform body 62, thus completing the separation of the vibration platform 3 from the platform body 62.

[0062] In addition, when the positioning hole 8 is set on the vibration platform 3, the positioning pin 7 is set on the platform body 62, and the corresponding insert plate 65 and driving element are set on the top of the vibration platform 3, the vibration platform 3 and the platform body 62 can also be fixed or detached.

[0063] Reference Figure 7 , Figure 8 In one embodiment, the suspended sliding vibratory coal press further includes a first damping mechanism and a second damping mechanism, wherein the first damping mechanism is disposed between the vibration platform 3 and the eccentric drive mechanism 51 and is configured to absorb radial vibration generated by the eccentric drive mechanism 51; the second damping mechanism is disposed between the vibration platform 3 and the eccentric drive mechanism 51 and is configured to absorb axial vibration generated by the eccentric drive mechanism 51.

[0064] In detail, the first damping mechanism includes a first connecting sleeve 52, a second connecting sleeve 53, and a plurality of first damping blocks 54. The first connecting sleeve 52 is a hexagonal support sleeve, fixedly connected to the vibration platform 3, and coaxially arranged with the output shaft of the eccentric drive mechanism 51. The second connecting sleeve 53 is also a hexagonal support sleeve, concentrically arranged with the first connecting sleeve 52. The second connecting sleeve 53 is coaxially arranged with the output shaft of the eccentric drive mechanism 51 and has a radial gap with the first connecting sleeve 52. The plurality of first damping blocks 54 are sequentially spaced circumferentially within the radial gap between the first connecting sleeve 52 and the second connecting sleeve 53, and are fixedly connected to the first connecting sleeve 52 and the second connecting sleeve 53.

[0065] The second damping mechanism includes a first connecting plate 55, a second connecting plate 56, and a plurality of second damping blocks 57. The first connecting plate 55 and the second connecting plate 56 are centrally symmetrical discs. Several installation positions for the second damping blocks are equally spaced around the center of symmetry at the edge of the discs. The second connecting sleeve 53 also includes plates extending outward along each side, which are inserted into the first connecting plate 55 at intervals and perpendicular to the output shaft of the eccentric drive mechanism 51. The second connecting plate 56 is fixedly connected to the hub housing of the eccentric vibrating wheel 5 and has an axial gap with the first connecting plate 55. The plurality of second damping blocks 57 are arranged circumferentially at intervals in the axial gap between the first connecting plate 55 and the second connecting plate 56 and are fixedly connected to the first connecting plate 55 and the second connecting plate 56.

[0066] Specifically, when the eccentric drive mechanism 51 is working, the radial vibration generated by the eccentric drive mechanism 51 is transmitted to the second connecting sleeve 53 through the first connecting plate 55. The multiple first damping blocks 54 are made of elastic material. The radial vibration on the second connecting sleeve 53 is absorbed by the multiple first damping blocks 54, so that the first connecting sleeve 52 and the vibration platform 3 remain radially stable.

[0067] The axial vibration generated by the eccentric drive mechanism 51 is transmitted to the second connecting plate 56. Multiple second damping blocks 57 absorb the axial vibration on the second connecting plate 56, maintaining the axial stability of the first connecting plate 55. This, in turn, stabilizes the second connecting sleeve 53 and the first connecting sleeve 52, which are fixedly connected to the first connecting plate 55. This two-stage damping system effectively blocks the vibration waves generated by the vibrating wheel from resonating with the overall frame of the equipment, thus ensuring the stability of the vibration platform and frame.

[0068] In addition, refer to Figure 7 Two coal baffles 58 are installed below the eccentric vibrating wheel 5. The two coal baffles 58 are respectively installed on both sides of the eccentric vibrating wheel 5 by bolts. When compacting coal powder, the coal press rolls over the coal powder, and the coal powder will be squeezed out from both sides and blocked by the coal baffles 58 to prevent a large amount of coal powder from overflowing.

[0069] In addition, refer to Figure 12 The machine also includes adjustment mechanisms for the two coal retaining plates 58. These mechanisms include a fixing member 591, an adjusting rod 592, and an adjusting plate 593. The fixing member 591 is bolted to the end of the eccentric vibrating wheel 5, and the adjusting plate 593 is bolted to the coal retaining plates 58. The fixing member 591 consists of two spaced-apart plates connected by pivots A and C. The adjusting plate 593 is connected to the pivot of the fixing member 591 via hinge point A and hinged to the adjusting rod 592 via hinge point B. The adjusting rod 592 rests on the pivot at point C of the fixing member 591 and can slide relative to the fixing member 591. When the coal press is operating, the coal retaining plates 58 are subjected to pressure from coal dust to the right. The adjusting plate 593 rotates counterclockwise relative to the fixing member 591 along hinge point A, and the adjusting rod 592 rotates counterclockwise relative to the adjusting plate 593 along hinge point B, while simultaneously sliding upwards. When the coal press stops working, under the action of gravity, the adjusting rod 592 slides downward from the rotating shaft at the fixed part 591C. The adjusting rod 592 rotates clockwise relative to the adjusting plate 593 around the hinge point B, and the adjusting plate 593 rotates clockwise relative to the fixed part 591 around the hinge point A. At the same time, the adjusting plate 593 abuts against the end faces of the left and right sides of the eccentric vibrating wheel 5. The angle of the coal retaining plate 58 is adjusted by the adjusting mechanism, which improves the adaptability of the coal retaining plate 58 when the coal press is working and prevents the coal retaining plate 58 from falling off due to excessive coal powder pressure.

[0070] In one embodiment, refer to Figure 9The suspended sliding vibratory coal press also includes a rotating shaft 32 and a piston cylinder 33. The two ends of the rotating shaft 32 are rotatably equipped with pressure rollers 9. The outer ends of the pressure rollers 9 protrude from the end edges of the eccentric vibratory wheel 5, and the axis of the rotating shaft 32 is parallel to the axis of the eccentric vibratory wheel 5. The pressure rollers 9 are located behind the eccentric vibratory wheel 5. The cylinder body of the piston cylinder 33 is fixedly mounted on the vibration platform 3. The piston rod of the piston cylinder 33 is fixedly connected to the rotating shaft 32 and located between the two pressure rollers 9. The pressure rollers 9 are configured to descend under the action of the piston cylinder 33 to contact the coal powder and smooth out the coal powder overflowing during the compaction process of the eccentric vibratory wheel 5 under the action of friction.

[0071] Specifically, the axis of the rotating shaft 32 is parallel to the axis of the eccentric vibrating wheel 5, and the pressure wheel 9 can also flatten the coal powder. The outer end of the pressure wheel 9 protrudes from the end edge of the eccentric vibrating wheel 5, and the pressure wheel 9 is located behind the eccentric vibrating wheel 5. When the eccentric vibrating wheel 5 compacts the coal powder, the overflowing coal powder on both sides of the wheel is smoothed out by the pressure wheel 9. The cylinder body of the piston cylinder 33 is fixedly mounted on the vibrating platform 3, and the piston rod of the piston cylinder 33 is fixedly connected to the rotating shaft 32 and located between the two pressure wheels 9. The piston cylinder 33 adjusts the edge of the pressure wheel 9 so that it protrudes from the lower edge of the eccentric vibrating wheel 5, thus more effectively smoothing out the overflowing coal powder.

[0072] Reference Figure 9 In one embodiment, the suspended sliding vibratory coal press further includes a floating spring mechanism, which includes a guide shaft 34 extending in the vertical direction. The upper end of the guide shaft extends into a guide hole 35 on the vibration platform 3, and the lower end is fixedly connected to the rotating shaft 32. A compression spring 36 is sleeved on the guide shaft 34, and the compression spring 36 is pre-pressed between the vibration platform 3 and the rotating shaft 32, and stores or releases energy during the process of the piston cylinder 33 driving the rotating shaft 32 to rise and fall relative to the vibration platform 3.

[0073] Specifically, when the pressure roller 9 needs to be lifted according to the coal powder height, the piston rod of the piston cylinder 33 retracts into the cylinder body, the piston rod pulls the rotating shaft 32 to move upward, the rotating shaft 32 compresses the spring 36 to retract and store elastic potential energy, the guide shaft 34 rises to be inserted into the guide hole 35 on the vibration platform 3, and the pressure roller 9 is lifted upward.

[0074] When the pressure roller 9 needs to be lowered according to the coal powder height, the compression spring 36 releases its elastic potential energy, pushing the rotating shaft 32 downward. The guide shaft 34 then exits from the guide hole 35 on the vibration platform 3, and the pressure roller 9 is lowered. This configuration, where the piston cylinder 33 drives the pressure roller 9 to rise and the compression spring 36 drives it to fall, allows for adjustment of the pressure roller 9's position according to the coal powder height, achieving better coal powder compaction. Furthermore, the compression spring 36 enables the pressure roller 9 to roll on uneven coal powder surfaces.

[0075] The coal pressing workstation includes a control room 10 and a suspended sliding vibration coal press as described in any of the above embodiments. The control room 10 is electrically connected to the first drive mechanism and the eccentric drive mechanism 51, and is configured to control the first drive mechanism to connect the vibration platform 3 to the walking mechanism 2 or to disconnect it from the walking mechanism 2, and to control the vibration waves generated by the eccentric drive mechanism 51 to repeatedly impact the coal on the top of the conveying equipment.

[0076] Specifically, the coal pressing station includes a suspended sliding vibratory coal press, thus possessing the same technical effects as a suspended sliding vibratory coal press. In addition, the coal pressing station is equipped with a control room 10, which can control the first drive mechanism to connect the vibration platform 3 to the walking mechanism 2 or disconnect it from the walking mechanism 2, and control the eccentric drive mechanism 51 to generate vibration waves, thereby realizing automated control of the operation of the suspended sliding vibratory coal press. Only one person is needed to complete the work, reducing labor costs.

[0077] Furthermore, to facilitate better understanding, the coal pressing process of this disclosure will be explained in detail below in conjunction with the actual application scenario of a suspended sliding vibration coal press.

Inside the control room 10, staff control the walking mechanism 2 to travel from the left side of the frame 1 to above the transport equipment via the suspended track 11; 3.
