Description

Technical Field

[0001] This invention relates to the field of coal chute technology, specifically to an online self-cleaning plow mechanism for coal chute. Background Technology

[0002] The function of the coal chute is to transport coal. Compared with the coal bunker, the cross-sectional area of ​​the coal chute is very small. When a large amount of coal enters the coal chute inlet directly, it is easy to cause blockage. Blockage of the coal chute can lead to interruption of transportation, accelerated wear and tear on equipment, and even safety accidents (such as the risk of coal dust explosion). In the coal processing industry, this can cause significant economic losses, including downtime losses and maintenance costs.

[0003] However, existing cleaning services require shutdown for cleaning, which presents a significant technical drawback:

[0004] First, existing cleaning mechanisms (such as fixed plows) cannot flexibly handle different blockage scenarios. For example, they cannot handle large areas or deep clumps of coal because these situations require variable unblocking depth and intensity, while fixed devices can only cover localized areas.

[0005] Secondly, existing cleaning services typically rely solely on mechanical unblocking (such as physical crushing with plows and rakes) or pneumatic blowing, but cannot combine both to handle complex problems. In particular, when wet materials clump together, the lack of hot air drying functionality leads to moisture residue and recurring blockages.

[0006] Third, the existing mechanisms (such as static air vents or fixed rakes) have limited range of motion and cannot reach the corners or deep areas of the feed box. This results in the blockage points not being completely cleared, causing the problem to recur and creating a vicious cycle of "cleaning-re-clogging". Summary of the Invention

[0013] Preferably, the air blowing component includes a cylinder fixedly connected to the inner side of the mounting frame, an air blowing impeller rotatably connected to the inner side of the cylinder, one side of the air blowing impeller being fixedly connected to the output shaft of the first motor, a plurality of evenly distributed air inlet holes being opened at one end of the cylinder, and an electric heating plate being fixedly connected to the inner wall of the cylinder.

[0014] Preferably, the extended compaction assembly includes several extension rods penetrating the second cavity of the plow and harrow rods, with a movable frame rotatably connected to the same end of the several extension rods, a cylinder fixedly connected to the outer side of the mounting frame, the output end of the cylinder fixedly connected to the movable frame, a second driving member for driving the extension rods to rotate provided at the bottom end of the movable frame, and an extension member provided at the other end of the several extension rods.

[0015] Preferably, the second driving component includes a second motor fixedly mounted on the outside of the mounting frame, the output shaft of the second motor being fixedly connected to a telescopic shaft, the telescopic shaft being rotatably connected to the movable frame, one end of the telescopic shaft being fixedly connected to a third gear, one end of each of the plurality of extension rods being fixedly connected to a fourth gear, and a fifth gear meshing between each two adjacent fourth gears, one of the fifth gears meshing with the third gear.

[0016] Preferably, the telescopic shaft includes a sleeve shaft rotatably connected to the movable frame, one end of the sleeve shaft is inserted into an insert shaft, one end of the insert shaft is fixedly connected to the output shaft of the two motors, a limit strip is fixedly connected to the outer side of the insert shaft, and a limit groove is provided on the inner wall of the sleeve shaft to fit the limit strip with a clearance.

[0018] The beneficial effects of this invention are:

[0019] 1. The pusher component drives the plow and rake rod to reciprocate in the feed box, crushing the accumulated coal material in real time, solving the pain point of traditional cleaning requiring machine shutdown and ensuring production continuity; at the same time, the first motor drives the blower impeller to generate hot air, which is introduced into the air hole of the plow and rake rod through the diversion pipe and sprayed out, directly acting on the blocked coal material, realizing the dual effect of mechanical unblocking and hot air drying, greatly improving the unblocking effect.

[0020] 2. The cylinder pushes the movable frame, causing the extension rod to extend from the end of the plow and rake, expanding the dredging depth and covering a large area of ​​blockage. The pressure spring automatically triggers the flipping rod to unfold, and combined with the second motor driving the gear set to drive the extension rod to rotate, realize circumferential and axial multi-dimensional material compaction, and thoroughly remove coal accumulation in the corners.

[0021] 3. The electric heating plate heats the intake air, and the high-temperature airflow is directly sprayed into the lumpy coal through the air holes, which quickly evaporates the moisture and loosens the wet coal, thus preventing secondary caking from the source. During the reciprocating motion of the plow and rake, the air holes cover different areas, achieving dynamic and uniform drying and avoiding the problem of repeated coal caking.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] This application discloses an online self-cleaning plow mechanism for a coal chute. Please refer to [link / reference]. Figure 1 and Figure 3 A self-cleaning plow mechanism for an online coal chute includes a coal chute body 1, a guide box 2 fixedly connected to the coal chute body 1, and cleaning mechanisms 3 on both sides of the guide box 2. The cleaning mechanism 3 includes a mounting frame 31, and a plurality of plow rods 32 equidistantly distributed along the length of the mounting frame 31 are fixedly connected to one end of the mounting frame 31. The plurality of plow rods 32 penetrate the inner wall of the guide box 2 and are slidably connected to the inner wall of the guide box 2. A first cavity 321 and a second cavity 322 are provided on the inner side of the plurality of plow rods 32. A plurality of evenly distributed air holes 34 are opened on the outer side of the first cavity 321. A pushing component 33 for driving the mounting frame 31 to reciprocate is provided at the top of the mounting frame 31. An air supply component 35 for introducing air into the first cavity 321 by cooperating with the activation of the pushing component 33 is provided on the inner side of the mounting frame 31. An extension tamping component 36 is provided on the inner side of the second cavity 322.

[0036] When the coal chute 1 is blocked, the push component 33 drives the mounting frame 31 to reciprocate, causing the mounting frame 31 to drive all the plow and rake rods 32 to insert into the guide box 2 and reciprocate. The plow and rake rods 32 clear the blocked coal in the guide box 2 through their movement, crushing the accumulated coal so that it can continue to fall downwards under gravity, effectively solving the problem of coal chute blockage. At the same time, the air supply component 35 introduces air into the first cavity 321, and then discharges it from each air hole 34 and blows it into the blocked coal. In conjunction with the reciprocating movement of the plow and rake rods 32, the air holes 34 blow air into the coal in different areas inside the guide box 2. This dries the moisture in the coal that has clumped due to water absorption inside the guide box 2, making the clumped coal looser and facilitating crushing and clearing inside the guide box 2, further improving the clearing effect. The entire structure can be cleaned and cleared online during the coal dropping process without stopping the machine for cleaning, greatly improving the continuous operation time and production efficiency of the equipment.

[0037] Please see Figures 1-4The pushing component 33 includes a fixed base 331 fixedly connected to the outside of the guide box 2. A guide rod 332 and a reciprocating screw 333 are fixedly connected to both ends of the fixed base 331, respectively. Both the guide rod 332 and the reciprocating screw 333 penetrate the side wall of the mounting frame 31 and are slidably connected to the mounting frame 31. A connecting plate 334 is fixedly connected to one end of the guide rod 332 and the reciprocating screw 333. An internal threaded sleeve 335, which is threadedly engaged with the reciprocating screw 333, is rotatably connected to the mounting frame 31. A first driving member is provided at the bottom end of the mounting frame 31 to drive the internal threaded sleeve 335 to rotate. The system includes a first gear 336 fixedly connected to one end of an internal threaded sleeve 335; a second gear 337 rotatably connected to one end of a mounting bracket 31, meshing with the first gear 336; a first bevel gear 338 coaxially fixedly connected to the second gear 337; a second bevel gear 339 rotatably connected to one end of the mounting bracket 31, meshing with the first bevel gear 338; a third bevel gear 330 coaxially fixed to the second bevel gear 339; a first motor 33b fixedly mounted at the bottom end of the mounting bracket 31; and a fourth bevel gear 33a meshing with the third bevel gear 330 fixedly connected to the output shaft of the first motor 33b.

[0038] During the blockage process, the coal material inside the feed box 2 is cleared by the plow and rake handle 32. The specific implementation process is as follows:

[0039] First, the first motor 33b is started to drive the fourth bevel gear 33a to rotate. Then, the third bevel gear 330 drives the second bevel gear 339 to rotate synchronously, which causes the first bevel gear 338 to drive the second gear 337 to rotate synchronously. This causes the first gear 336 to rotate, causing the internal threaded sleeve 335 to rotate relative to the reciprocating screw 333. Under the restriction and guidance of the guide rod 332, the internal threaded sleeve 335 will reciprocate along the axis of the reciprocating screw 333, which causes the entire mounting frame 31 to reciprocate. This allows all the plow and rake rods 32 to be inserted into the feed box 2 and reciprocate. The plow and rake rods 32 clear the coal blocked inside the feed box 2 through their movement, crush the accumulated coal and allow it to continue to fall downwards under the action of gravity, effectively solving the problem of coal pipe blockage.

[0040] Please see Figure 1 and Figure 7The air supply assembly 35 includes several air inlet pipes 351 that communicate with the first cavity 321 of the plowing rod 32. The top ends of the several air inlet pipes 351 are fixedly connected to the diverter pipes 352. One end of the diverter pipes 352 is fixedly connected to the air guide pipe 353. The inlet end of the air guide pipe 353 is provided with an air blowing component for guiding air into the air guide pipe 353. The air blowing component includes a cylinder 354 fixedly connected to the inner side of the mounting bracket 31. A blower impeller 355 is rotatably connected to the inner side of the cylinder 354. One side of the blower impeller 355 is fixedly connected to the output shaft of the first motor 33b. One end of the cylinder 354 is provided with several evenly distributed air inlet holes 356. An electric heating plate 357 is fixedly connected to the inner wall of the cylinder 354.

[0041] The specific implementation process of blowing air into the coal through the vent 34 during the blockage process to dry the moisture in the agglomerated coal is as follows:

[0042] During the startup process of the first motor 33b, the first motor 33b simultaneously drives the blower impeller 355 to rotate, which reduces the internal pressure of the cylinder 354, allowing the air inlet 356 to draw external air into the cylinder 354. At the same time, the electric heating plate 357 is energized and heats up, thus heating the air inside the cylinder 354. The hot air is then introduced into the diversion pipe 352 through the air guide pipe 353, and then diverted into the corresponding first cavity 321 through each air inlet pipe 351. The air is then discharged from each air hole 34 and blown into the blocked coal. In conjunction with the reciprocating movement of the plow and rake rod 32, the air holes 34 blow hot air out of the coal in different areas of the feed box 2. This dries the moisture in the coal that has clumped due to water absorption inside the feed box 2, making the clumped coal looser and facilitating the crushing and unblocking inside the feed box 2, further improving the unblocking effect.

[0043] Please see Figure 1 and Figure 9The extended tamping assembly 36 includes several extension rods 361 penetrating the second cavity 322 of the plow and harrow rods 32. A movable frame 362 is rotatably connected to the same end of each extension rod 361. A cylinder 363 is fixedly connected to the outside of the mounting frame 31. The output end of the cylinder 363 is fixedly connected to the movable frame 362. A second driving component for driving the extension rods 361 to rotate is provided at the bottom end of the movable frame 362. The second driving component includes a second motor 366 fixedly mounted on the outside of the mounting frame 31. A telescopic shaft 367 is fixedly connected to the output shaft of the second motor 366. The telescopic shaft 367 is rotatably connected to the movable frame 362. A third gear 368 is fixedly connected to one end of the telescopic shaft 367. A third gear 368 is fixedly connected to one end of each of the extension rods 361. Four gears 369, each of two adjacent fourth gears 369 is meshed with a fifth gear 360, one of the fifth gears 360 meshes with a third gear 368, and the other end of several extension rods 361 is provided with an extension member 365, the extension member 365 includes several sliders 3651 slidably connected to the end of the extension rods 361, the sliders 3651 are distributed at equal angles around the extension rods 361, one end of the sliders 3651 is hinged to a connecting rod 3652, the end of the connecting rods 3652 away from the sliders 3651 is hinged to a flipping rod 3653, the other end of the sliders 3651 is welded with a pressure spring 3654, the end of the pressure spring 3654 away from the sliders 3651 is welded to the inner wall of the extension rods 361.

[0044] When the area of ​​coal blockage inside the feed box 2 is too large and the range of motion of the plow and rake rod 32 cannot be fully covered, the movable frame 362 is driven to move closer to the plow and rake rod 32 by the control cylinder 363, so that all the extension rods 361 extend from the end of the plow and rake rod 32. This can extend the axial material clearing range to cover the blockage area and meet the needs of various blockage states.

[0045] Simultaneously, after the extension rod 361 extends, under the action of the pressure spring 3654, the slider 3651 slides and drives the connecting rod 3652 to rotate upward, causing the connecting rod 3652 to drive the flipping rod 3653 to unfold at a certain angle. At the same time, the second motor 366 is started to drive the telescopic shaft 367 to rotate, causing the third gear 368 to rotate, which in turn causes the fifth gear 360 to rotate synchronously. Under the transmission action of multiple fifth gears 360, all the fourth gears 369 rotate synchronously, which causes all the extension rods 361 to rotate, and all the flipping rods 3653 to rotate circumferentially. This allows for circumferential guidance of the coal, thereby achieving multi-directional guidance of the blocked coal, greatly improving the unblocking effect and shortening the unblocking time.

[0046] Please see Figures 1-10The telescopic shaft 367 includes a sleeve shaft 3671 rotatably connected to the movable frame 362. One end of the sleeve shaft 3671 is inserted into a plug shaft 3672. One end of the plug shaft 3672 is fixedly connected to the output shaft of the second motor 366. A limit strip 3673 is fixedly connected to the outer side of the plug shaft 3672. A limit groove 3674 with clearance fit to the limit strip 3673 is provided on the inner wall of the sleeve shaft 3671.

[0047] The limiting strip 3673 can restrict the relative rotation between the insert shaft 3672 and the sleeve shaft 3671, thus ensuring that the insert shaft 3672 always rotates synchronously with the sleeve shaft 3671 during axial movement, thereby ensuring stable power transmission.

[0048] Working principle: When the inside of the coal chute 1 is blocked, the first motor 33b is started to drive the fourth bevel gear 33a to rotate. Then the third bevel gear 330 drives the second bevel gear 339 to rotate synchronously, which causes the first bevel gear 338 to drive the second gear 337 to rotate synchronously. This causes the first gear 336 to rotate, which causes the internal threaded sleeve 335 to rotate relative to the reciprocating screw 333. Under the restriction and guidance of the guide rod 332, the internal threaded sleeve 335 will reciprocate along the axis of the reciprocating screw 333, which causes the entire mounting frame 31 to reciprocate. This allows all the plow and rake rods 32 to be inserted into the guide box 2 and reciprocate. The plow and rake rods 32 guide the blocked coal inside the guide box 2 through their movement, crush the accumulated coal and allow it to continue to fall downward under the action of gravity, effectively solving the problem of coal chute blockage.

[0049] During the startup process of the first motor 33b, the first motor 33b simultaneously drives the blower impeller 355 to rotate, which reduces the internal pressure of the cylinder 354, allowing the air inlet 356 to draw external air into the cylinder 354. At the same time, the electric heating plate 357 is energized and heats up, thus heating the air inside the cylinder 354. The hot air is then introduced into the diversion pipe 352 through the air guide pipe 353, and then diverted into the corresponding first cavity 321 through each air inlet pipe 351. The air is then discharged from each air hole 34 and blown into the blocked coal. In conjunction with the reciprocating movement of the plow and rake rod 32, the air holes 34 blow hot air out of the coal in different areas of the feed box 2. This dries the moisture in the coal that has clumped due to water absorption inside the feed box 2, making the clumped coal looser and facilitating the crushing and unblocking inside the feed box 2, further improving the unblocking effect.

[0050] When the area of ​​coal blockage inside the feed box 2 is too large and the range of motion of the plow and rake rod 32 cannot be fully covered, the movable frame 362 is driven to move closer to the plow and rake rod 32 by the control cylinder 363, so that all the extension rods 361 extend from the end of the plow and rake rod 32. This can extend the axial material clearing range to cover the blockage area and meet the needs of various blockage states.

[0051] Simultaneously, after the extension rod 361 extends, under the action of the pressure spring 3654, the slider 3651 slides and drives the connecting rod 3652 to rotate upward, causing the connecting rod 3652 to drive the flipping rod 3653 to unfold at a certain angle. At the same time, the second motor 366 is started to drive the telescopic shaft 367 to rotate, causing the third gear 368 to rotate, which in turn causes the fifth gear 360 to rotate synchronously. Under the transmission action of multiple fifth gears 360, all the fourth gears 369 rotate synchronously, which causes all the extension rods 361 to rotate, and all the flipping rods 3653 to rotate circumferentially. This allows for circumferential guidance of the coal, thereby achieving multi-directional guidance of the blocked coal, greatly improving the unblocking effect and shortening the unblocking time.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
