Description

Technical Field

[0001] This application relates to the field of coal conveying technology, and more specifically, to a cleaning structure for a coal conveyor. Background Technology

[0002] Belt conveyors are one of the most commonly used conveying equipment in the coal industry. They are characterized by large conveying capacity, high efficiency, and stable operation. They are widely used in coal mining, transportation, coal preparation plants and other scenarios. However, because fine powder, moisture or sticky substances in coal can easily adhere to the surface of the conveyor belt and drum, the drum diameter is uneven, causing the conveyor belt to run off-track. Therefore, a cleaning mechanism is needed to clean the conveyor.

[0003] Existing conveyor belt cleaning mechanisms, such as cleaning brushes, are prone to attracting coal sludge and entanglement of debris, reducing cleaning effectiveness. These mechanisms are mostly single-unit designs, requiring the conveyor belt to be paused for self-cleaning or maintenance of the cleaning components; this makes continuous operation difficult, interrupting cleaning and reducing efficiency. Utility Model Content

[0004] To address the aforementioned problems, this application provides a cleaning structure for a coal conveyor.

[0005] The cleaning structure for a coal conveyor provided in this application adopts the following technical solution:

[0006] A cleaning structure for a coal conveyor includes a connecting frame disposed on one side of the machine body, and a cleaning component disposed on the inner side of the connecting frame;

[0007] The cleaning assembly includes a connecting frame, a rotating rod rotatably connected to the inner side of the connecting frame, the connecting frame and the rotating rod being fixedly connected, a brush rotatably connected to each end of the connecting frame, a second motor on one side of the connecting frame, and an auxiliary fixing assembly above the second motor.

[0008] Through the above technical solution, the cleaning component can continuously clean the non-load-bearing surface of the conveyor belt during the operation of the conveyor, effectively removing the adhering coal slime and coal powder, and preventing residual materials from entering the drum. This achieves the effect of preventing the conveyor belt from running off-track or wearing out, and ensuring the stable operation of the conveyor.

[0009] Furthermore, the auxiliary fixing component includes a reciprocating lead screw, which is rotatably connected to the connecting frame. A slider is threaded onto the outer wall of the reciprocating lead screw, and both ends of the slider are fixedly connected to limit plates. One end of each limit plate passes through the connecting frame and is slidably connected to the connecting frame.

[0010] Furthermore, a second gear is fixedly connected to one end of both the reciprocating lead screw and the rotating rod. The rotating rod is fixedly connected to the output end of the second motor. The two second gears mesh with each other, and one of the second gears has a one-way bearing inside.

[0011] Furthermore, a first motor is provided at the end of the connecting frame away from the second motor, and a first gear is fixedly connected to the shaft inside each brush. The first gear is also fixedly connected to the output shaft of the first motor.

[0012] Furthermore, a cleaning box is provided at the bottom of the connecting frame, and a connecting pipe is provided on one side of the cleaning box. One end of the connecting pipe is connected to multiple nozzles.

[0013] Furthermore, the cleaning tank is equipped with a cleaning brush inside, and a splash guard is fixedly connected to the end of the cleaning tank away from the nozzle.

[0014] Furthermore, a sewage pipe is connected to the bottom of the cleaning tank, and a baffle plate is fixedly connected to each end of the connecting frame near the first motor. A third motor is provided at the end of the connecting frame near the first motor, and the output end of the third motor is connected to a third gear through a rotating shaft.

[0015] With the above technical solution, after the brush has been used for a period of time, it can be transferred into the cleaning tank. The third motor drives the brush to rotate, and with the spray nozzle spraying cleaning fluid and the cleaning brush working together, the brush can be self-cleaned. This achieves timely removal of coal sludge from the brush, maintains the brush's cleanliness, reduces the number of interruptions, and improves efficiency.

[0016] Furthermore, the connecting frame is equipped with a controller, which is electrically connected to the first motor, the second motor and the third motor.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) By setting the cleaning component, the brush can continuously clean the non-load-bearing surface of the conveyor belt during the operation of the conveyor, effectively removing the adhering coal slurry and coal powder, and preventing residual materials from entering the drum, thereby preventing the conveyor belt from running off track or wearing out, and ensuring the stable operation of the conveyor.

[0019] (2) With the setting of a second motor, a cleaning box, a third motor, a nozzle and a cleaning brush, the brush can be transferred into the cleaning box after a period of use. The third motor drives the brush to rotate, and with the spraying of cleaning liquid from the nozzle and the action of the cleaning brush, the brush can be self-cleaned, thus removing coal sludge from the brush in time, maintaining the brush in a clean state, reducing the number of interruptions and improving efficiency.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figures 1-5 A cleaning structure for a coal conveyor includes a connecting frame 2 disposed on one side of the body 1, and a cleaning component disposed on the inner side of the connecting frame 2.

[0028] The cleaning component includes a connecting frame 4, a rotating rod 5 rotatably connected to the inner side of the connecting frame 2, the connecting frame 4 and the rotating rod 5 being fixedly connected, a brush 6 rotatably connected to each end of the connecting frame 4, a second motor 9 being provided on one side of the connecting frame 2, and an auxiliary fixing component being provided above the second motor 9.

[0029] When the machine body 1 is running, a brush 6 is located below the conveyor belt of the machine body 1. The first motor 3 drives the brush 6 to rotate through the first gear 7. The brush 6 rotates to clean the conveyor belt. During the process of conveying materials by the conveyor belt of the machine body 1, the coal slurry and coal powder adhering to the non-bearing surface of the conveyor belt can be cleaned to prevent residual materials from entering the drum and causing the conveyor belt to run off-center or wear.

[0030] Reference Figures 3-4The auxiliary fixing component includes a reciprocating lead screw 12, which is rotatably connected to the connecting frame 2. A slider 13 is threadedly connected to the outer wall of the reciprocating lead screw 12. Limiting plates 14 are fixedly connected to both ends of the slider 13. One end of the two limiting plates 14 passes through the connecting frame 2 and is slidably connected to the connecting frame 2. A second gear 10 is fixedly connected to one end of the reciprocating lead screw 12 and the rotating rod 5. The rotating rod 5 is fixedly connected to the output end of the second motor 9. The two second gears 10 mesh with each other, and one of the second gears 10 has a one-way bearing inside.

[0031] When the second motor 9 drives the connecting frame 4 to rotate, the two limiting plates 14 are flush with the inner side of the connecting frame 2, which does not hinder the rotation of the connecting frame 4. After the connecting frame 4 has rotated, the first gear 7 of the brush 6 meshes with the first gear 7 of the first motor 3. At this time, the second motor 9 can rotate in the opposite direction. Since the second gear 10 on the reciprocating screw 12 is equipped with a one-way bearing, when the second motor 9 reverses, it can drive the reciprocating screw 12 to rotate, thereby driving the limiting plate 14 to move and clamp one end of the connecting frame 4 to prevent it from shifting due to vibration and other factors during the cleaning process, thus ensuring that the cleaning work is carried out stably and efficiently.

[0032] Reference Figures 3-5 The first motor 3 is provided at the end of the connecting frame 2 away from the second motor 9. The shaft inside each brush 6 is fixedly connected to the first gear 7, and the shaft at the output end of the first motor 3 is also fixedly connected to the first gear 7.

[0033] Reference Figures 4-5 The bottom of the connecting frame 2 is provided with a cleaning box 18. A connecting pipe 19 is provided on one side of the cleaning box 18. One end of the connecting pipe 19 is connected to multiple nozzles 20. A cleaning brush 21 is provided inside the cleaning box 18. A splash guard 17 is fixedly connected to the end of the cleaning box 18 away from the nozzles 20. A sewage pipe 11 is connected to the bottom of the cleaning box 18. A baffle plate 8 is fixedly connected to each end of the connecting frame 4 near the first motor 3. A third motor 15 is provided at the end of the connecting frame 2 near the first motor 3. The output end of the third motor 15 is connected to a third gear 16 through a rotating shaft.

[0034] When one of the cleaning brushes 6 has been used for a period of time, the second motor 9 drives the connecting frame 4 to rotate, transferring the used brush 6 into the cleaning tank 18. At this time, the third gear 16 meshes with the first gear 7, and the third motor 15 drives the brush 6 to be cleaned to rotate through the third gear 16. Simultaneously, the connecting pipe 19 introduces cleaning fluid and sprays it onto the surface of the brush 6 through the nozzle 20 under high pressure. As the brush 6 rotates, it continuously contacts the cleaning brush 21, working together to remove the coal sludge from the brush 6. The splash plate 17 and the baffle plate 8 prevent the cleaning fluid from overflowing and avoid water splashing onto the third gear 16 and the first gear 7. The wastewater after cleaning is discharged through the wastewater pipe 11. After cleaning, the cleaned brush 6 can be air-dried on the upper side of the cleaning tank 18. When cleaning one brush 6, some dust may fall off, but the cleaned brush 6 will dry under normal working conditions (dust concentration ≤ 50 mg / m³). 3 The amount of secondary dust falling off the brush only accounts for 3%-5% of the brush bristle load, which is far lower than the effective cleaning capacity of the brush 6.

[0035] Reference Figures 1-5 The internal part of the connecting frame 2 is equipped with a controller, which is electrically connected to the first motor 3, the second motor 9 and the third motor 15.

[0036] When the system needs to be started, the operator presses the external "Start Cleaning" button. Upon receiving the signal, the controller drives the first motor 3 to operate, causing the brush 6 to begin cleaning the conveyor belt. To adjust the angle or position of the brush 6, the operator presses the "Angle Adjustment" button. The controller then controls the second motor 9 to rotate, which in turn rotates the brush 6 via the rotating rod 5 and connecting frame 4. When the brush 6 needs self-cleaning, the operator presses the "Self-Cleaning Start" button. The controller then starts the third motor 15, driving the cleaning brush 21 to clean the brush 6. The operator can flexibly control the operation of each motor using external buttons with different functions, switching between different working states such as conveyor belt cleaning, brush 6 position adjustment, and self-cleaning.

[0037] Working Principle: During use, the operator presses the "Start Cleaning" button, and the controller controls the first motor 3 to operate. The first gear 7 drives the brush 6 to rotate, cleaning the non-load-bearing surface of the conveyor belt and preventing coal sludge and dust from entering the drum and causing misalignment or wear. If brush 6 needs to be adjusted or replaced for cleaning, the "Angle Adjustment" button is pressed. The second motor 9 drives the rotating rod 5 and connecting frame 4 to rotate. During this process, the limiting plate 14 of the auxiliary fixing component is flush with the inner side of the connecting frame 2 to avoid interference. When the connecting frame 4 rotates to its position, the first gear 7 of the brush 6 meshes with the first gear 7 of the first motor 3. The second motor 9 then rotates in the opposite direction, utilizing the one-way bearing on the reciprocating screw 12 to move the limiting plate 14, clamping and fixing the connecting frame 4 to ensure stable cleaning operation.

[0038] When brush 6 needs cleaning after a period of use, the second motor 9 drives the connecting frame 4 to rotate, transferring the brush 6 to be cleaned into the cleaning tank 18. At this time, the third gear 16 meshes with the first gear 7 of brush 6. Pressing the "self-cleaning start" button starts the third motor 15, which drives the brush 6 to rotate via the third gear 16. Simultaneously, the connecting pipe 19 introduces cleaning fluid, which is then sprayed at high pressure through the nozzle 20, working in conjunction with the cleaning brush 21 to remove the coal sludge from brush 6. The splash guard 17 and the baffle 8 prevent the cleaning fluid from overflowing, and wastewater is discharged through the wastewater pipe 11. After cleaning, brush 6 is allowed to air dry on the upper side of the cleaning tank 18.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
