[0032] Combination Figure 1-5As shown, a vibrating coal preparation machine includes: a base 1, a sliding box 2, a screen box 3, a first drive mechanism 4, a second drive mechanism 5, and a stirring assembly 6; the base 1, the sliding box 2, and the screen box 3 are arranged sequentially from bottom to top; the sliding box 2 includes a box body 21 and a first baffle 22, the top of the box body 21 has a collection space 23 for collecting coal blocks, the first baffle 22 is movably connected to the front end of the box body 21 to cover or open the front end of the collection space 23, and the box body 21 can slide relative to the base 1 in the front-back direction; the screen box 3 includes a screen frame 31, a screen mesh 32, and a second baffle 33, the screen mesh 32 is fixedly connected to the bottom of the screen frame 31. The screen frame 31 has a screening space 34 for screening coal blocks inside. The second baffle 33 is movably connected to the front end of the screen frame 31 to cover or open the front end of the screening space 34. The screen frame 31 is installed on the box 21 through the first drive mechanism 4. The first drive mechanism 4 can drive the front and rear ends of the screen box 3 to swing up and down relative to the sliding box 2. The second drive mechanism 5 is installed on the screen box 3. The stirring assembly 6 is located in the screening space 34 and is fixedly connected to the power output end of the second drive mechanism 5. The second drive mechanism 5 can drive the stirring assembly 6 to stir the coal blocks in the screening space 34.
[0033] In this embodiment, coal blocks are first placed in the screen box 3, and the first drive mechanism 4 is activated. The screen box 3 swings relative to the sliding box 2, and the center of gravity of the screen box 3 relative to the base 1 changes. The sliding box 2 automatically adapts to the change and slides back and forth relative to the base 1. Under such vibration, the coal blocks in the screen box 3 are automatically screened and filtered. Small coal blocks fall from the screen 32 into the sliding box 2, while large coal blocks remain in the screen box 3. At the same time, the second drive mechanism 5 is activated to drive the stirring assembly 6, so that the stirring assembly 6 can move relative to the screen box 3 to fully agitate the coal blocks, which is conducive to small coal blocks falling into the sliding box 2. After the coal blocks are screened, the first drive mechanism 4, the second drive mechanism 5, and the stirring assembly 6 are turned off. After the action of multiple drive modes, the vibrating coal separator of this application has completed the full screening of the coal blocks. Adjusting the first baffle can discharge small coal blocks from the sliding box 2, and adjusting the second baffle can discharge large coal blocks from the screen box 3.
[0034] Furthermore, the base 1 includes a seat body 11 and a guide rod 12. The guide rod 12 is fixedly connected to the seat body 11 and extends in the front-to-back direction. The sliding box 2 also includes a slider 24, which is fixedly connected to the bottom of the box body 21. The slider 24 is sleeved on the outer periphery of the guide rod 12 and slidably connected to the guide rod 12. When the first driving mechanism 4 drives the screen box 3 to swing relative to the sliding box 2, the box body 21 slides relative to the base 1 in the front-to-back direction via the slider 24.
[0035] Furthermore, a spring 121 is sleeved on the guide rod 12, and the front and rear ends of the slider 24 are respectively fixedly connected to the spring 121. For example, the sliding box 2 first slides forward, compressing the spring 121 in front of the slider 24. When the sliding box 2 has a tendency to slide backward, the compressed spring 121 acts on the slider 24, assisting the sliding box 2 to slide backward and compress the spring 121 behind the slider 24. This allows the sliding box 2 to continue sliding when the first drive mechanism 4 is started. That is, while the screen box 3 swings relative to the sliding box 2, it also moves back and forth relative to the slider 24, which is beneficial for the coal in the screen box 3 to be automatically screened during vibration.
[0036] Furthermore, the first driving mechanism 4 is located on the same side of the housing 21 and the screen frame 31 in the left-right direction. The first driving mechanism 4 includes a first motor 41, a crank assembly 42, and a support rod 43. The lower end of the support rod 43 is rotatably connected to the housing 21, and the upper end of the support rod 43 is rotatably connected to the screen frame 31. The first motor 41 is fixedly installed on the housing 21. The crank assembly 42 includes a rotating block 421 and a connecting rod 422. One end of the rotating block 421 is fixedly connected to the power output shaft of the first motor 41, one end of the connecting rod 422 is rotatably connected to the other end of the rotating block 421, and the other end of the connecting rod 422 is rotatably connected to the screen frame 31.
[0037] For example, the first drive mechanism 4 is installed on the left side of the housing 21 and the screen frame 31. There are two support rods 43, which are spaced apart between the front end and the rear end of the connecting rod 422. The support rods 43 are connected to the sliding box 2 and the screen box 3 respectively by pins. When the first motor 41 is driven, its power output shaft drives the rotating block 421 to rotate. The front end of the connecting rod 422 rotates with the rotating block 421 to realize the swing of the connecting rod 422. The rear end of the connecting rod 422 is connected to the screen frame 31. Under the swing action of the connecting rod 422, the screen box 3 swings relative to the sliding box 2. The support rods 43 provide good support for the screen box 3 while ensuring that the screen box 3 swings relative to the sliding box 2.
[0038] Furthermore, the stirring assembly 6 includes a third driving mechanism 61 and a stirring element 62. The stirring element 62 is slidably connected to the power output end of the third driving mechanism 61. The second driving mechanism 5 includes a second motor 51, a threaded rod 52, and a threaded block 53. The second motor 51 is located on one side of the screen frame 31 in the front-rear direction. The threaded rod 52 is connected to the driving end of the second motor 51 and is rotatably connected to the screen frame 31. The threaded rod 52 extends along the front-rear direction of the screen frame 31. The threaded block 53 is sleeved on the outer periphery of the threaded rod 52 and screwed onto the threaded rod 52. One side of the threaded block 53 is slidably connected to the inner wall of the screen frame 31, and the other side is fixedly connected to the third driving mechanism 61. The second motor 51 can drive the threaded rod 52 to rotate, thereby causing the threaded block 53 to slide relative to the screen frame 31.
[0039] In this embodiment, after the second motor 51 is started, the threaded block 53 slides back and forth along the extension direction of the threaded rod 52, driving the stirring assembly 6 to slide back and forth in the screen box 3. At the same time, the third drive mechanism 61 is started to drive the stirring component 62, which is beneficial to agitate the coal in the entire screen box 3, reduce the adhesion of the screen 32 to the coal, make the screen 32 screen the coal more thoroughly, and facilitate the subsequent cleaning of the screen 32.
[0040] Further, the third drive mechanism 61 includes a third motor 611 and a reciprocating column 612. The third motor 611 is fixedly connected to the threaded block 53, and the reciprocating column 612 is fixedly connected to the power output shaft of the third motor 611. The stirring component 62 includes a reciprocating rod 621 and a turning roller 622. The reciprocating rod 621 has a mounting hole 6211, which extends along the front-rear direction of the sieve frame 31. The reciprocating column 612 is slidably connected within the mounting hole 6211, and the turning roller 622 is fixedly connected to the side of the reciprocating rod 621 away from the third motor 611. The turning rollers 622 are spaced apart on both sides of the mounting hole 6211. The turning rollers 622 extend along the left and right direction of the screen frame 31. The top of the reciprocating rod 621 is fixedly connected to the reciprocating block 6212. The top of the threaded block 53 is fixedly connected to the limiting block 531. The limiting block 531 is provided with a reciprocating groove 5311. The reciprocating groove 5311 extends along the up and down direction of the screen frame 31. The reciprocating block 6212 is slidably connected to the reciprocating groove 5311. The third motor 611 can drive the reciprocating column 612 to rotate, thereby driving the stirring element 62 to slide relative to the threaded block 53 in the up and down direction.
[0041] For example, the threaded block 53 is slidably connected to the inner right side of the screen frame 31, the stirring assembly 6 is located on the left side of the threaded block 53, the reciprocating block 6212 is L-shaped, one end of which is connected to the reciprocating rod 621 and the other end is connected to the limiting block 531. The reciprocating column 612 is fixedly connected to the power output shaft of the third motor 611 through the rotating plate 613. When the third motor 611 is driven, the reciprocating column 612 rotates circumferentially and slides back and forth in the mounting hole 6211. Due to the limiting effect of the limiting groove on the limiting block 531, the reciprocating column 612 cannot drive the reciprocating rod 621 to rotate. The reciprocating rod 621 can only move back and forth in the vertical direction relative to the third motor 611, which facilitates the turning roller 622 to turn the coal blocks in the screen box 3 up and down. With the synchronous drive of the second motor 51, the turning roller 622 moves up and down while moving back and forth in the screen box 3, so that the coal blocks are distributed more evenly, thereby avoiding the situation that the coal blocks in the upper layer of the screen box 3 are not fully screened.
[0042] Furthermore, the vibrating coal preparation machine also includes a water spraying mechanism 7, which includes a mounting frame 71, a water tank 72, a water pump 73, and an atomizing spray pipe 74. The mounting frame 71 is fixedly connected to the top of the screen frame 31, the water tank 72 is rotatably connected to the mounting frame 71, the water pump 73 is fixedly connected to the bottom of the water tank 72, the water inlet end of the atomizing spray pipe 74 is fixedly connected to the water outlet end of the water pump 73, and the water outlet end of the atomizing spray pipe 74 is spaced above the screen 32. The water pump 73 can transport water from the water tank 72 to the atomizing spray pipe 74 for spraying.
[0043] Since the adhesion of some small coal particles and mud clumps to the screen 32 has been reduced after the stirring component 6 has been fully stirred, the screen 32 can be cleaned by starting the water pump 73 and spraying water through the atomizing nozzle 74 after the coal has been screened.
[0044] Furthermore, the water spraying mechanism 7 also includes a mounting block 75, a fourth motor 76, and a gear 77. A gear ring 711 and a slide rail 712 arranged along the outer periphery of the gear ring 711 are fixedly connected to the mounting bracket 71. The mounting block 75 is slidably connected to the slide rail 712. The water tank 72 and the fourth motor 76 are respectively fixedly connected to the mounting block 75, and the water tank 72 is located inside the gear ring 711. The gear 77 is meshed with the inner periphery of the gear ring 711. The driving end of the fourth motor 76 is connected to the gear 77 to drive the gear 77 to rotate around the inner side of the gear ring 711.
[0045] In this embodiment, when cleaning the screen 32, the fourth motor 76 drives the gear 77 to rotate, which will cause the mounting block 75 to slide in the slide rail 712. The atomizing spray pipe 74 sprays water while rotating around the inner side of the gear ring 711, which helps to increase the water spraying area and improve the cleaning efficiency of the screen 32.
[0046] Furthermore, the water spraying mechanism 7 also includes a water outlet cylinder 78 and a fan blade 79. The water outlet cylinder 78 is fixedly connected to the lower part of the mounting block 75. The atomizing spray pipe 74 passes through the water outlet cylinder 78 and is fixedly connected to the water outlet cylinder 78. The water outlet end of the atomizing spray pipe 74 communicates with the inside of the water outlet cylinder 78. The bottom of the water outlet cylinder 78 is provided with an opening for water spraying. The fan blade 79 is installed inside the water outlet cylinder 78 and passes through the top of the water outlet cylinder 78. The fan blade 79 is spaced above the water outlet end of the atomizing spray pipe 74 and is fixedly connected to the bottom of the gear 77.
[0047] In this embodiment, when the fourth motor 76 drives the gear 77 to rotate, the fan blade 79 also rotates, providing wind power to the atomized water, increasing the water spraying distance, and making the water spraying range cover the entire screen 32. This helps to save the process of manually cleaning the screen 32 and realize the automatic cleaning of the screen 32.
[0048] Furthermore, the first baffle 22 is slidably connected to the front end of the box 21, and the second baffle 33 is slidably connected to the front end of the screen frame 31. After screening, the first baffle 22 can be slidably pulled out of the box 21, allowing small pieces of coal to be discharged from the front end of the sliding box 2, and the second baffle 33 can be slidably pulled out of the box frame, allowing large pieces of coal to be discharged from the front end of the screen box 3.
