Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor with a cleaning function. Background Technology

[0002] Belt conveyor systems are core continuous conveying equipment widely used in industries such as mining, metallurgy, chemicals, food processing, warehousing and logistics, and assembly manufacturing. Their core working principle involves a series of interconnected circular belts carrying materials, which are then driven by friction from a drive roller to circulate, continuously transporting materials from the loading point to the designated unloading point. Due to its advantages of large conveying capacity, long conveying distance, simple structure, and high reliability, this equipment has become an indispensable key link in material flow in modern industrial production.

[0003] When conveyor belt systems transport coal, ore, grain, powdery materials, or oily components, material residues (such as dust, debris, and oil stains) easily adhere to the belt surface or become embedded in its texture, causing belt contamination and material waste. Currently, this relies mainly on manual cleaning at regular intervals, requiring operators to clean manually while the equipment is stopped. This method is not only labor-intensive and inefficient, but frequent shutdowns also severely disrupt the production process, affecting overall operational continuity and production efficiency. Furthermore, manual cleaning cannot guarantee consistent cleaning quality, leaving blind spots. Long-term accumulation of these residues will accelerate belt wear, cause belt misalignment, and potentially lead to cross-contamination, failing to meet the actual needs of continuous and automated production.

[0004] Therefore, it is necessary to design a belt conveyor with a cleaning function to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of belt conveyors, such as the tendency for materials to remain after being transported, requiring manual cleaning and resulting in low efficiency, production interruptions, and damage to the belts due to incomplete cleaning, which can lead to belt misalignment and contamination, and make it difficult to meet the requirements of continuous automation, this utility model provides a belt conveyor with a cleaning function.

[0006] The technical implementation scheme of this utility model is as follows: a belt conveyor with cleaning function includes a support frame, a control box, a motor, rollers, and a conveyor belt. The control box and the motor are fixedly connected to the front of the support frame. The motor is electrically connected to the control box and is located on the left side of the control box. Rollers are rotatably connected to both sides of the top of the support frame. The output shaft of the motor passes through the inside of the support frame and is fixedly connected to one of the rollers. A conveyor belt is wound between the two rollers. The system also includes mounting blocks, a dial, a cleaning brush, abutment blocks, torsion springs, connecting rods, and a collection frame. Mounting blocks are symmetrically fixedly connected to both sides of the support frame. A dial is fixedly connected to one side of one of the rollers through the support frame. A cleaning brush is rotatably connected between two mounting blocks. Abutment blocks are fixedly connected to the rear of each cleaning brush through corresponding mounting blocks. Torsion springs are connected between each abutment block and its corresponding rear mounting block. A connecting rod is rotatably connected between the lower parts of the two abutment blocks. A collection frame is connected between the bottoms of the two mounting blocks on the same side.

[0007] Furthermore, multiple levers are fixedly arranged in a ring array on the outside of the dial. Each lever has an inclined structure on one side, and a protrusion is fixed on the upper part of the abutment block on one side. The protrusion abuts and cooperates with the corresponding lever.

[0008] Furthermore, both collection boxes are located below the corresponding cleaning brushes.

[0009] Furthermore, it also includes guide frames, sliders, bearings, connecting cylinders, connecting ropes, and counterweights. Guide frames are fixedly connected to both sides of the middle of the support frame. Sliders are slidably connected inside the two guide frames. Bearings are fixedly connected inside the two sliders. Connecting cylinders are fixedly connected between the inner rings of the two bearings. The connecting cylinders roll in cooperation with the inside of the conveyor belt. Connecting ropes are fixedly connected to the bottom of the two sliders. The bottom of the two connecting ropes passes through the corresponding guide frames and are fixedly connected to counterweights.

[0010] Furthermore, it also includes an air intake hood, an air supply pipe, and an air pump. The air intake hoods are fixedly connected to both sides of the top of the support frame. The bottom of each air intake hood has an air intake port. The top of each air intake hood is connected to and connected to an air supply pipe. The left side of each air supply pipe is connected to and connected to an air pump. Both air pumps are electrically connected to the control box.

[0011] Furthermore, both air intakes are located above the gap between the conveyor belt and the support frame.

[0012] The present invention has the following advantages: 1. The present invention sets up a mechanical linkage cleaning mechanism consisting of a dial, a lever, abutment block and torsion spring. By utilizing the power of the main drive roller of the conveyor belt, the cleaning brush is automatically driven to perform high-frequency reciprocating oscillation, thereby achieving synchronous cleaning of the working surface of the belt during the conveying process. This achieves the effect of effectively removing adhering dust and particulate matter, replacing manual cleaning, ensuring the cleanliness of the conveyed products and improving production efficiency.

[0013] 2. This utility model uses a gravity tensioning mechanism consisting of a counterweight, a connecting rope, and a slider to apply a constant downward tension to the conveyor belt and can automatically compensate for the elongation of the belt caused by long-term use. This achieves the effect of always maintaining the belt at a moderate tension, effectively preventing the conveyor belt from slipping, and ensuring transmission stability and consistent cleaning effect.

[0014] 3. This utility model adds a negative pressure dust collection function consisting of an air pump, a suction hood, and an air delivery pipe, which removes scattered fine dust while mechanically sweeping, effectively suppressing dust generated during the cleaning process, improving the air quality of the working environment, and achieving a comprehensive cleaning effect that combines dry sweeping and negative pressure dust collection.

Detailed Implementation

[0031] Example: A belt conveyor line with cleaning function, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 13 and Figure 14As shown, the system includes a support frame 1, a control box 2, a motor 3, rollers 4, a conveyor belt 5, mounting blocks 6, a dial 7, a cleaning brush 8, abutment blocks 9, a torsion spring 10, a connecting rod 11, and a collection frame 12. The control box 2 is screwed onto the left front side of the support frame 1, and the motor 3 is screwed onto the left front side of the support frame 1. The motor 3 is electrically connected to the control box 2 and is located to the left of the control box 2. Rollers 4 are rotatably connected to the top left and right sides of the support frame 1. The output shaft of the motor 3 passes through the support frame 1 and is connected to the left roller 4 via a coupling. A conveyor belt 5 is wound between the two rollers 4. Mounting blocks 6 are symmetrically mounted on the front and rear sides of the support frame 1 via screws. The rear side of the left roller 4 passes through... A dial 7 is mounted on the support frame 1 by screws. A cleaning brush 8 is rotatably mounted between two mounting blocks 6 on the left and right sides by screws. Each cleaning brush 8 extends out of the corresponding mounting block 6 and is fixedly connected to an abutment block 9. Multiple levers are welded in a circular array on the outer side of the dial 7. Each lever is inclined on the side away from the dial 7. A protrusion is fixed on the upper part of the abutment block 9 on the left side. The protrusion abuts and cooperates with the corresponding lever. A torsion spring 10 is connected between each abutment block 9 and the corresponding mounting block 6 on the rear side. A connecting rod 11 is rotatably connected between the lower sides of the two abutment blocks 9. A collection frame 12 is connected between the bottom sides of the two mounting blocks 6 on the left and right sides. Both collection frames 12 are located directly below the corresponding cleaning brush 8.

[0032] like Figure 1 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes guide frames 13, sliders 14, bearings 15, connecting cylinders 16, connecting ropes 17, and counterweights 18. Guide frames 13 are installed on both the front and rear sides of the middle of the support frame 1 by screws. Sliders 14 are slidably connected inside the two guide frames 13. Bearings 15 are fixedly connected inside the two sliders 14. Connecting cylinders 16 are fixedly connected between the inner rings of the two bearings 15. Connecting cylinders 16 roll with the lower side of the inside of the conveyor belt 5. Connecting ropes 17 are fixedly connected to the bottom side of the two sliders 14. The bottom ends of the two connecting ropes 17 pass through the corresponding guide frames 13 and are fixedly connected to the counterweights 18.

[0033] like Figure 1 , Figure 13 , Figure 14 and Figure 15 As shown, it also includes a suction hood 19, an air supply pipe 20, and an air pump 21. Suction hoods 19 are installed on the front and rear sides of the top of the support frame 1 by screws. Suction ports are opened on the bottom sides of the two suction hoods 19. The two suction ports are located above the gap between the conveyor belt 5 and the support frame 1. The top sides of the two suction hoods 19 are connected to and connected to the air supply pipe 20. The left ends of the two air supply pipes 20 are connected to and connected to the air pump 21. The two air pumps 21 are electrically connected to the control box 2.

[0034] When starting this device for material conveying, the motor 3 is first started via the control box 2. The output shaft of the motor 3 drives the left roller 4 to rotate clockwise. Through friction transmission between the two rollers 4, the conveyor belt 5 begins to circulate continuously, thus conveying the material on it from one end to the other. While the conveyor belt 5 is running, the cleaning function is activated simultaneously. The left roller 4 drives the dial 7 to rotate synchronously, and multiple levers rotate accordingly. When the inclined surface of a lever contacts the protrusion and continues to rotate, it will exert a rightward pressure on the protrusion. This rightward pressure pushes the left abutment block 9 to overcome the torque of the torsion spring 10, driving the cleaning brush 8 to the right. The oscillating motion, under the action of the connecting rod 11, causes the cleaning brush 8 on the other side to move synchronously, making the bristles of the two cleaning brushes 8 more tightly pressed against the working surface of the conveyor belt 5. After the lever continues to rotate past the rightmost point, its pressure on the protrusion is gradually released. At this time, under the restoring torque of the torsion spring 10, the abutment block 9 drives the cleaning brush 8 to swing to the left to reset, waiting for the arrival of the next lever. This cycle repeats, and the cleaning brush 8 performs high-frequency, rhythmic up-and-down slapping motions under the drive of the motor 3, thereby efficiently shaking off and sweeping away the dust and particles adhering to the surface of the conveyor belt 5. The swept-off waste falls directly into the collection frame 12, completing the collection.

[0035] To further ensure the stable operation of the conveyor belt 5 and provide a stable cleaning working surface, the counterweight 18 continuously applies a downward pulling force to the slider 14 through the connecting rope 17. This pulling force is ultimately applied to the lower side of the conveyor belt 5 through the bearing 15 and the connecting cylinder 16, so that it always maintains a constant tension. If the conveyor belt 5 stretches due to long-term use, the counterweight 18 will automatically pull down, causing the slider 14 to slide down along the guide frame 13, thereby automatically compensating for the elongation without manual intervention. This constant tension effectively prevents the conveyor belt 5 from slipping and ensures the stability of the cleaning effect of the cleaning brush 8.

[0036] To further enhance the cleaning effect, two air pumps 21 can be activated via control box 2. The air pumps 21 generate suction through the air supply pipe 20 and suction hood 19. The suction ports located above both sides of the conveyor belt 5 draw in fine dust particles scattered in the air during the cleaning process, effectively improving the air quality of the working environment and achieving a combined cleaning method of dry sweeping and negative pressure vacuuming. When it is necessary to stop the device, first turn off the air pumps 21 via control box 2 to stop the vacuuming function. Then turn off the motor 3, the conveyor belt 5 stops running, and the dial 7 also stops rotating. The cleaning brush 8, under the action of the torsion spring 10, finally returns to its initial raised state, ceasing contact with the conveyor belt 5. Operators can periodically pull out the collection box 12 to empty the collected waste, and then push the collection box 12 back into its original position, thus completing all reset and maintenance work.
