Description

Technical Field

[0001] This invention relates to the field of coal mining technology, specifically to a vertical coal mining machine for inclined coal seam working faces and its usage method. Background Technology

[0002] Coal mining machines are one of the main pieces of equipment in fully mechanized coal mining systems, evolving from coal cutters. A coal mining machine is a large, complex system integrating mechanical, electrical, and hydraulic components, and is a crucial piece of equipment for achieving mechanization and modernization in coal mine production. Mechanized coal mining can reduce manual labor, improve safety, and achieve high output, high efficiency, and low consumption. However, traditional coal mining machines face many inconveniences when mining inclined coal faces. For example, they cannot operate at different inclination angles, and the large amount of dust generated during mining cannot be effectively suppressed, thus accelerating mechanical wear, worsening the working environment, and even causing explosions at certain concentrations of dust, posing significant hidden dangers to coal mining operations. Summary of the Invention

[0003] The purpose of this invention is to provide a vertical coal mining machine for inclined coal seam working faces and its usage method, so as to solve the problems mentioned in the background art.

[0004] The objective of this invention can be achieved through the following technical solutions:

The other side of the upper and lower rectangular plates is equipped with a guide rod. Both the threaded rod and the guide rod are equipped with two sets of corresponding connectors. A central frame is installed between each set of connectors. Multiple sets of adjustment slots are opened on the central frames on both sides, and an adjustment block is slidably installed in each set of adjustment slots.

[0010] A synchronization frame is installed together among multiple adjusting blocks on the same side. A drive motor is fixedly installed on one adjusting block. A coal mining drum is fixedly installed at the output end of the drive motor. The side of the coal mining drum away from the drive motor is rotatably connected to the adjusting block on the other side. A protruding plate is provided on the rear side of the synchronization frame and fixedly connected to the middle frame. An electric push plate is fixedly installed on the side of the protruding plate close to the synchronization frame. The telescopic end of the electric push plate is fixedly connected to the synchronization frame.

[0011] The spraying unit includes vertical poles located on the upper and lower sides of the central frame and rotatably connected to them. An outer frame is installed between the upper and lower vertical poles. A side spraying plate is rotatably installed in the middle of the outer frame. Restriction frames are installed at the upper and lower rear of the side spraying plate. A support plate is fixedly installed below the rear of the side spraying plate.

[0014] A cam is mounted on the side strip via an electric slider. Below the cam is a stop plate that is fixedly connected to the side strip. The lower part of the cam is always in contact with the lifting frame. A vertical plate is fixedly mounted in the middle of the lower end face of the lifting frame. The vertical plate is slidably connected to the side strip and passes through the stop plate. A spring is sleeved on the outside of the lifting frame. Multiple sets of adjustment plates are rotatably mounted on the front side of the vertical plate. The multiple sets of adjustment plates are rotatably connected to multiple vacuum cleaner cylinders.

[0015] Preferably, another object of the present invention is to provide a method for using a vertical coal mining machine in an inclined coal seam working face, comprising the following steps:

[0016] S1: Device tilted:

[0017] Rotate the flip handle according to the inclined surface of the coal wall. When the flip handle is rotated, the large gear drives the small gear, which in turn tilts the flip rod and the horizontal adjustment unit above it so that it fits against the inclined coal wall. At this time, the electric slider is activated and drives the synchronous rod to rotate. When the synchronous rod rotates, the steel rope on the fixed wheel is released to cooperate with the tilting operation of the horizontal adjustment unit.

[0018] S2: Coal mining operations:

[0019] Once the coal cutting drum is in contact with the coal wall, the drive motor is turned on. When the drive motor is turned on, multiple coal cutting drums rotate to perform coal cutting operations on the coal wall. The coal cutting depth of the coal cutting drum can be controlled by extending and retracting the electric push rod.

[0020] S3: Dust removal operation:

[0021] When the coal mining drum is mining the coal face, the side spray plates and the rotating atomizing plates are activated to spray and suppress dust, thereby reducing the spread of dust. The electric slider drives the push-pull wheel to rotate, which in turn causes the lifting frame to rise and fall intermittently, thus constantly changing the suction angle of multiple dust collection cylinders. Then, the dust collection fan is turned on to absorb the dust generated during coal mining and put it into the dust collection bag, effectively avoiding accelerated mechanical wear.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention achieves synchronous flipping of the horizontal and vertical adjustment units through a flip handle and gear system, which fits the coal wall and improves the efficiency of coal mining drum operation. The horizontal and horizontal adjustment of the coal mining drum is achieved by using a drive handle and belt system to adapt to different coal mining positions.

[0024] 2. This invention achieves vertical movement adjustment of the coal mining drum through the design of threaded rods and connecting parts, quickly adjusting the coal mining position. The outer frame unfolding and spray plate design reduce dust splashing. At the same time, the push-pull wheels and flip plates achieve atomized dust suppression, and the dust collection fan and electric slider system effectively collect dust.

[0025] 3. This invention achieves multi-angle adjustment of the dust collection cylinder through the linkage of the cam and the lifting frame, thereby improving dust collection efficiency. The method is simple and easy to operate, and can achieve precise adjustment and dust control, thereby improving the efficiency and safety of coal mining operations. Attached Figure Description

[0041] like Figures 1-12 As shown, the coal mining machine includes a placement frame 1, a horizontal adjustment unit 2 is provided on the front side of the placement frame 1, a vertical adjustment unit 3 is provided in the middle of the horizontal adjustment unit 2, multiple coal mining drums 4 are provided in the middle of the vertical adjustment unit 3, spraying units 5 are provided on both sides and the rear of the vertical adjustment unit 3, and dust collection units 6 are provided on both sides of the horizontal adjustment unit 2.

[0042] A flipping rod 11 is horizontally rotatably mounted on the front side of the placement frame 1. A small gear 12 is fixedly mounted on one side of the flipping rod 11. A flipping handle 13, which is threadedly rotatably connected to the placement frame 1, is provided at the rear of the small gear 12. A large gear 14, which meshes with the small gear 12, is fixedly mounted on the flipping handle 13. Curved plates 15 are fixedly mounted on both sides of the rear of the placement frame 1. A synchronous rod 16 is rotatably mounted between the two curved plates 15 via an electric slider. A fixed wheel 17, which is fixedly connected to the synchronous rod 16, is provided in the middle of the curved plate 15. A steel rope 18 is wound on the fixed wheel 17. A connecting plate 19 is fixedly mounted at one end of the steel rope 18. One end of the connecting plate 19 is fixedly connected to the horizontal adjustment unit 2. By rotating the flipping handle 13, the flipping handle 13 drives the small gear 12 to rotate through the large gear 14, thereby causing the horizontal adjustment unit 2 on the flipping rod 11 to flip. When the horizontal adjustment unit 2 flips, the vertical adjustment unit 3 provided in its middle also flips synchronously until it fits against the inclined coal wall, so that the coal mining drum 4 can carry out coal mining operations on the coal wall.

[0043] like Figure 1 , Figure 7 , Figure 8 As shown, the lateral adjustment unit 2 includes two ear plates 20 correspondingly installed on the flip rod 11. Two end plates 21 arranged vertically are provided above the ear plates 20. The lower end plate 21 is fixedly connected to the ear plates 20 on both sides. Two sets of side strips 28 are installed between the upper and lower end plates 21. A dovetail groove 22 is opened on the side of the upper and lower end plates 21 that is close to each other.

[0044] Sliders 23 are slidably mounted on both sides of the dovetail groove 22. A rotating shaft 24, rotatably connected to the end plate 21, is mounted on one side of each slide 23. One rotating shaft 24 is threadedly connected to the end plate 21. Both the slide 23 and the rotating shaft 24 are equipped with wheels 25, which are rotatably connected to the slide 23. Retracting blocks 26 are symmetrically mounted on both sides of the end plate 21. The wheels 25 are driven by a belt 27, with both ends of the belt 27 fixedly connected to the retracting blocks 26 on both sides. The lower side of the rotating shaft 25... A drive handle 29 is fixedly installed on the wheel 25. When the coal mining drum 4 needs to be adjusted laterally during coal mining, the drive handle 29 is rotated to make the wheel 25 below rotate clockwise or counterclockwise. At this time, the belt 27 drives multiple wheels 25 to rotate. When the wheel 25 on the slide 23 rotates, the two slides 23 in the dovetail groove 22 drive the rectangular plate 30 to adjust left and right, thereby adjusting the entire vertical adjustment unit 3 left and right, and finally making the coal mining drum 4 perform horizontal adjustment operation.

[0045] The vertical adjustment unit 3 includes two rectangular plates 30, which are fixedly connected to two upper and lower slides 23 respectively. A threaded rod 31 is mounted on one side of the upper and lower rectangular plates 30 through an electric slider. A guide rod 32 is provided on the other side of the upper and lower rectangular plates 30. Two sets of corresponding connecting parts 33 are provided on the threaded rod 31 and the guide rod 32. A central frame 34 is installed between each set of connecting parts 33. Multiple sets of adjustment slots 35 are opened on the central frames 34 on both sides. An adjustment block 36 is slidably installed in each set of adjustment slots 35.

[0046] A synchronization frame 37 is installed between multiple adjusting blocks 36 on the same side. A drive motor 38 is fixedly installed on one adjusting block 36, and a coal mining drum 4 is fixedly installed at the output end of the drive motor 38. The side of the coal mining drum 4 away from the drive motor 38 is rotatably connected to the adjusting block 36 on the other side. A protruding plate 39 is provided on the rear side of the synchronization frame 37 and is fixedly connected to the middle frame 34. An electric push plate 390 is fixedly installed on the side of the protruding plate 39 near the synchronization frame 37. The telescopic end of the electric push plate 390 is fixedly connected to the synchronization frame 37. When the coal mining depth of the coal mining drum 4 is adjusted, the electric push plate 390 extends and retracts, thereby driving the adjusting blocks 36 to slide in the adjusting groove 35. At this time, multiple The coal mining drum 4 is adjusted forward and backward to ultimately adjust the depth of coal mining. When the coal mining drum 4 needs to be adjusted vertically during coal mining, the electric slider is activated to drive the threaded rod 31 to rotate. When the threaded rod 31 rotates, it drives the two connecting parts 33 above it to move up and down. At this time, the middle frame 34 between the two connecting parts 33 moves up and down synchronously. The two connecting parts 33 on the guide rod 32 slide on the guide rod 32, ultimately allowing the coal mining drum 4 between the two middle frames 34 to move and adjust vertically, thereby enabling the coal mining drum 4 to quickly adjust to different coal mining positions during coal mining operations.

[0047] like Figure 4 , Figure 5 , Figure 8 As shown, the spraying unit 5 includes vertical rods 51, which are located on the upper and lower sides of the central frame 34 and are rotatably connected to it. An outer frame 52 is installed between the upper and lower vertical rods 51. A side spraying plate 53 is rotatably installed in the middle of the outer frame 52. A limiting frame 54 is installed on the upper and lower rear of the side spraying plate 53. A support plate is fixedly installed below the rear of the side spraying plate 53. A water tank 55 is placed on the support plate. The water tank 55 is located inside the upper and lower limiting frames 54. A connecting pipe 56 connects the water tank 55 and the side spraying plate 53. A rear plate 57 is fixedly installed on the rear of the two central frames 34.

[0048] The upper and lower ends of the rear plate 57 are slidably mounted with sliding rods 58, and a U-shaped frame 59 is installed between the two sliding rods 58. A rotating atomizing plate 590 is rotatably mounted inside the U-shaped frame 59. A center handle 591 is threadedly mounted on the middle of the rear side of the rear plate 57. A push-pull wheel 592 is fixedly mounted on the center handle 591. Push-pull plates 593 are hinged to both sides of the push-pull wheel 592. The side of the two push-pull plates 593 away from the push-pull wheel 592 is respectively hinged to the upper and lower U-shaped frames 59. The upper and lower rotating atomizing plates 590 are connected to the water storage tanks 55 on both sides by a water supply pipe 594. When the coal mining drum 4 is mining the coal wall, the outer frames 52 on both sides are unfolded by rotating the vertical rods 51 on both sides, and then the side spray plates 53 are opened to spray the coal wall. Spraying is carried out on both sides of the coal mining area to reduce dust splashing during coal mining. At the same time, the rotating center 591 causes the push-pull wheel 592 to rotate. When the push-pull wheel 592 rotates, the distance between the upper and lower C-shaped frames 59 is adjusted through the push-pull plate 593. Then, the tilting plate atomizer 590 is turned on to atomize and suppress dust on the upper and lower parts of the coal mining drum 4. The water storage tank 55 can supply water to the side spraying plate 53 and the tilting plate atomizer 590 through the connecting pipe 56 and the water supply pipe 594 respectively. The rear plate 57 is located at the rear of the coal mining drum 4 to block the dust generated during coal mining, so that the dust diffuses to all sides. Then, the dust is suppressed under the action of the side spraying plate 53 and the tilting atomizer 590.

[0049] The vacuum unit 6 includes a rotating shaft 61. Multiple rotating shafts 61 are rotatably installed between each set of side strips 28. A vacuum tube 62 is fixedly installed between each set of rotating shafts 61. A vacuum fan 63 is fixedly installed in the middle of the vacuum tube 62. A dust collection bag 69 is installed at the rear of the multiple vacuum tubes 62 on the same side.

[0050] A cam 64 is rotatably mounted on the side strip 28 via an electric slider. Below the cam 64 is a stop plate 65 fixedly connected to the side strip 28. The lower part of the cam 64 always contacts the lifting frame 66. A vertical plate 67 is fixedly mounted in the middle of the lower end face of the lifting frame 66. The vertical plate 67 is slidably connected to the side strip 28 and passes through the stop plate 65. A spring is sleeved on the outside of the lifting frame 66. Multiple sets of adjusting plates 68 are rotatably mounted on the front side of the vertical plate 67. These adjusting plates 68 are rotatably connected to multiple dust collection cylinders 62. By turning on the dust collection fan 63, the diffused dust generated during coal mining can be sucked up. The dust is collected and stored in the dust collection bag 69. When the dust collection cylinders 62 on both sides collect dust from different angles, the electric slider is opened to drive the cam 64 to rotate. When the cam 64 rotates, it pushes the lifting frame 66 to slide. When the lifting frame 66 slides up and down, it drives the vertical plate 67 to slide up and down on the side wall of the side strip 28. When the vertical plate 67 slides up and down, it drives the dust collection cylinder 62 and the rotating shaft 61 to rotate between the two side strips 28 through multiple adjusting plates 68, thereby changing the dust collection position of the dust collection cylinder 62, and finally achieving a thorough dust collection operation for the dust that permeates during coal mining.

[0051] like Figures 1-12 As shown, another objective of the present invention is to provide a method for using a vertical coal mining machine in an inclined coal seam working face, comprising the following steps:

[0052] S1: Device tilted:

[0053] Rotate the flip handle 13 according to the inclined surface of the coal wall. When the flip handle 13 rotates, the large gear 14 drives the small gear 12, which in turn tilts the flip rod 11 and the horizontal adjustment unit 2 above it so that it fits against the inclined coal wall. At this time, the electric slider is turned on and drives the synchronous rod 16 to rotate. When the synchronous rod 16 rotates, the steel rope 18 on the fixed wheel 17 is released to cooperate with the tilting operation of the horizontal adjustment unit 2.

[0054] S2: Coal mining operations:

[0055] When the coal mining drum 4 comes into contact with the coal wall, the drive motor 38 is turned on. When the drive motor 38 is turned on, multiple coal mining drums 4 rotate to carry out coal mining operations on the coal wall. The coal mining depth of the coal mining drum 4 can be controlled by the extension and retraction of the electric push plate 390.

[0056] S3: Dust removal operation:

[0057] When the coal mining drum 4 is mining the coal wall, the side spray plate 53 and the rotating atomizing plate 590 are opened to spray and reduce dust during mining, thereby reducing the spread of dust. The electric slider is opened to drive the push-pull wheel 592 to rotate. When the push-pull wheel 592 rotates, it drives the lifting frame 66 to lift intermittently, thereby continuously changing the suction angle of multiple dust suction cylinders 62. Then, the dust suction fan 63 is turned on to absorb the dust generated during coal mining and put it into the dust collection bag 69, effectively avoiding accelerated mechanical wear.

[0058] When in use, the present invention rotates the flip handle 13 according to the inclined surface of the coal wall to be mined. When the flip handle 13 rotates, the large gear 14 drives the small gear 12, which in turn tilts the flip rod 11 and the horizontal adjustment unit 2 above it so that it fits against the inclined coal wall. At this time, the electric slider is turned on and drives the synchronous rod 16 to rotate. When the synchronous rod 16 rotates, the steel rope 18 on the fixed wheel 17 is released to cooperate with the tilting operation of the horizontal adjustment unit 2.

[0059] After the coal mining drum 4 is in contact with the coal wall, the drive motor 38 is turned on. When the drive motor 38 is turned on, multiple coal mining drums 4 rotate to perform coal mining operations on the coal wall. When the coal mining drum 4 needs to be adjusted laterally during coal mining, the drive handle 29 is turned to make the wheel 25 below rotate clockwise or counterclockwise. At this time, the belt 27 drives multiple wheels 25 to rotate. When the wheel 25 on the slide 23 rotates, the two slides 23 in the dovetail groove 22 drive the rectangular plate 30 to adjust left and right, thereby adjusting the entire vertical adjustment unit 3 left and right, and finally making the coal mining drum 4 perform horizontal adjustment operations.

[0060] When the coal mining depth of the coal mining drum 4 is adjusted, the electric push plate 390 extends and retracts, thereby driving the adjusting block 36 to slide within the adjusting groove 35. At this time, multiple coal mining drums 4 are adjusted back and forth, ultimately adjusting the depth of the coal mining drum 4 when mining the coal wall. When the coal mining drum 4 needs to be adjusted vertically during coal mining, the electric slider is activated, driving the threaded rod 31 to rotate. When the threaded rod 31 rotates, it drives the two connecting parts 33 above it to move up and down. At this time, the middle frame 34 between the two connecting parts 33 moves up and down synchronously. The two connecting parts 33 on the guide rod 32 slide on the guide rod 32, ultimately allowing the coal mining drum 4 between the two middle frames 34 to move and adjust vertically, thereby enabling the coal mining drum 4 to quickly adjust to different coal mining positions during coal mining operations.

[0061] Rotating the vertical rods 51 on both sides unfolds the outer frames 52 on both sides. Then, the side spraying plates 53 are opened to spray the sides of the coal mining area to reduce dust splashing during coal mining. At the same time, rotating the center handle 591 causes the push-pull wheel 592 to rotate. When the push-pull wheel 592 rotates, the distance between the upper and lower C-shaped frames 59 is adjusted through the push-pull plate 593. Then, the tilting plate atomizer 590 is opened to atomize and reduce dust on the upper and lower parts of the coal mining drum 4. The water storage tank 55 can supply water to the side spraying plates 53 and the tilting plate atomizer 590 through the connecting pipe 56 and the water supply pipe 594 respectively. The rear plate 57 is located at the rear of the coal mining drum 4 to block the dust generated during coal mining, causing the dust to diffuse in all directions. Then, the dust is reduced by the action of the side spraying plates 53 and the tilting plate atomizer 590.

[0062] The electric slider is controlled to open, which drives the cam 64 to rotate. When the cam 64 rotates, it pushes the lifting frame 66 to slide. When the lifting frame 66 slides up and down, it drives the vertical plate 67 to slide up and down on the side wall of the side strip 28. When the vertical plate 67 slides up and down, it drives the dust suction cylinder 62 and the rotating shaft 61 to rotate between the two side strips 28 through multiple adjusting plates 68, thereby changing the dust suction position of the dust suction cylinder 62, and finally achieving a thorough dust suction operation for the dust that permeates during coal mining.

5. A method of using a vertical coal mining machine for inclined coal seam working faces according to any one of claims 1-4, characterized in that, The method of use includes the following steps: S1: Device tilted: According to the tilting surface of the coal wall, the flip handle (13) is rotated. When the flip handle (13) is rotated, the large gear (14) drives the small gear (12), which in turn tilts the flip rod (11) and the horizontal adjustment unit (2) above it so that it fits against the tilted coal wall. At this time, the electric slider is turned on to drive the synchronous rod (16) to rotate. When the synchronous rod (16) rotates, the steel rope (18) on the fixed wheel (17) is released to cooperate with the tilting operation of the horizontal adjustment unit (2). S2: Coal mining operations: When the coal mining drum (4) comes into contact with the coal wall, the drive motor (38) is turned on. When the drive motor (38) is turned on, multiple coal mining drums (4) rotate to carry out coal mining operations on the coal wall. The coal mining depth of the coal mining drum (4) can be controlled by the extension and retraction of the electric push plate (390). S3: Dust removal operation: When the coal mining drum (4) is mining the coal wall, the side spray plate (53) and the flip atomizing plate (590) are turned on to spray dust during coal mining, thereby reducing the spread of dust. The electric slider is turned on to drive the cam (64) to rotate. When the cam (64) rotates, it drives the lifting frame (66) to lift intermittently, thereby changing the suction angle of multiple dust suction cylinders (62). Then the dust suction fan (63) is turned on to absorb the dust generated during coal mining and put it into the dust collection bag (69), effectively avoiding accelerated mechanical wear.
