Description

Technical Field

[0001] The invention belongs to the technical field of packaging, and in particular relates to a transmission roller of an anti-skidding coal conveyor belt. Background Art

[0002] In the field of coal transportation, coal conveyor belts are crucial equipment, carrying the heavy responsibility of transporting coal from mining sites and storage points to processing areas or other designated locations. As the core component of coal conveyor belts, the drive roller is responsible for providing power to the conveyor belt. The friction between the roller and the conveyor belt drives the conveyor belt, achieving efficient coal transportation.

[0003] In actual operating conditions, coal conveyor belts often face complex and harsh working environments. For one thing, coal moisture levels are difficult to maintain consistently. High coal moisture content can cause the belt surface to become slippery during conveyance. For example, in open-pit coal mines, the moisture content of the coal mined after rainfall increases significantly. When conveying this type of coal, the friction between the drive drum and the belt is significantly reduced due to the moisture. Furthermore, coal particle size varies significantly, and large particles accumulate unevenly on the belt, which can easily cause belt stress imbalances. Furthermore, the load conditions of coal conveyor belts vary during operation. Significant static friction must be overcome at startup, and heavy-load operation places even higher demands on the friction between the drive drum and the belt. In actual production, coal throughput fluctuates frequently due to adjustments to production plans or fluctuations in upstream mining volumes, resulting in continuously fluctuating loads.

[0004] The drive rollers of traditional coal conveyor belts have numerous drawbacks when dealing with these situations. Most traditional drive rollers have simple smooth or ordinary rubber coatings. In humid, heavily loaded conditions, the friction between the smooth roller and the belt is severely insufficient, making it prone to slipping. Even with a rubber coating, the rubber wears out over time and under harsh operating conditions, significantly reducing its anti-slip properties. Furthermore, while increasing friction by increasing belt tension can alleviate the slippage problem to a certain extent, it can also increase belt and roller wear, shortening the equipment's service life. Excessive tension can also cause serious failures, such as belt breakage, increasing equipment maintenance costs and downtime, negatively impacting the continuity of coal production and transportation. Summary of the Invention

[0005] In response to the above problems, the present invention proposes a transmission roller for an anti-skid coal conveyor belt, which can effectively prevent coal powder from depositing on the transmission roller and improve the anti-skid performance of the transmission roller, thereby reducing equipment loss, extending equipment service life, and reducing maintenance costs.

When the second end of the swing plate is separated from the support column under the action of the cover plate unfolding mechanism, the swing plate contacts the cleaning mechanism and the cleaning mechanism cleans its outer wall.

[0007] Optionally, a plurality of swing shafts are provided in a circular array on the support ring, and each swing shaft is provided with a support spring; a swing sleeve is provided on the first end of the swing plate and is sleeved on the swing shaft, and the support spring is in elastic contact with the inner wall of the swing sleeve.

[0008] Optionally, a plurality of protrusions are arranged in an array on each swing plate.

[0009] Optionally, a plurality of ash discharge holes are arranged in an array on each swing plate, each protrusion is arranged at the edge of the corresponding ash discharge hole, and all the protrusions and all the ash discharge holes are integrally punched and bent.

[0010] Optionally, an adjustment column is provided on the end of each support column away from the swing plate, an adjustment seat is provided on the support ring, and the adjustment column and the adjustment seat are threadedly connected.

[0011] Optionally, a connecting column is provided at the end of each adjusting column, a plurality of coupling protrusions are provided in an array on the surface of the connecting column, and the supporting column is fixedly connected to the adjusting column through the connecting column.

[0012] Optionally, the support frame is a hollow structure, comprising a plurality of connecting arms each arranged along a circumferential surface of the connecting axis.

[0013] Optionally, the fan in the air inlet cavity is connected to a centrifugal impeller, and arc-shaped guide vanes are provided in the air inlet cavity. The guide vanes are arranged around the centrifugal impeller, and exhaust gaps are provided between the guide vanes.

[0014] Optionally, the cleaning mechanism includes an exhaust pipe, and at least two groups of cleaning wheels are provided at the opening of the exhaust pipe. Each cleaning wheel is driven to rotate by a driving member, and each cleaning wheel is provided with a cleaning brush.

[0015] Optionally, at least two arc-shaped blowing cavities are provided on the side wall of the exhaust pipe, each cleaning wheel is located in a corresponding blowing cavity, the side wall of each blowing cavity is connected to a blowing pipe, each blowing pipe is provided with a secondary axial flow fan, and the air outlet direction of each secondary axial flow fan is toward the corresponding blowing cavity and toward the roller mechanism; Optionally, a main axial flow fan is provided in the exhaust duct, and the air outlet direction of the main axial flow fan is arranged away from the roller mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention proposes a transmission roller of an anti-skid coal conveyor belt, which can effectively prevent coal powder from depositing on the transmission roller and improve the anti-skid performance of the transmission roller, thereby reducing equipment loss, extending equipment service life, and reducing maintenance costs.

[0017] Furthermore, the swing plates in the annular array on the support ring of the present invention can be adjusted during normal operation to change the contact angle and area between the drive roller and the belt by adjusting the swing plate's swing angle. When the coal conveyor belt is under heavy load or when the belt surface is slippery, the swing plates can be adjusted accordingly to increase the friction between the swing plates and the belt, ensuring that the drive roller can stably drive the belt and effectively preventing slippage.

[0018] Furthermore, the present invention further enhances the friction coefficient with the belt by providing an array of raised elements on the swing plate. These elements engage the belt surface, providing additional grip, especially at the moment of contact between the belt and the roller, effectively reducing belt slippage on the roller. Whether overcoming static friction during startup or managing varying loads during operation, the raised elements significantly enhance the drive roller's anti-slip capabilities.

[0019] Furthermore, the air blowing assembly of the cover plate deployment mechanism of the present invention draws air into the air inlet chamber via a fan, which then blows it toward the support ring through an exhaust nozzle. During the cleaning phase, the airflow assists in blowing away dust, dislodging coal dust accumulated on the swing plate and support ring and discharging it through the exhaust duct, keeping the drive roller surface clean and preventing dust accumulation from affecting friction. Furthermore, when the swing plate is deployed and contacts the cleaning brush, the airflow enhances the brush's cleaning effect on the swing plate, ensuring that coal residue on the swing plate surface is completely removed, achieving air-assisted cleaning.

[0020] Furthermore, the swing plate of the present invention knocks against the support ring when it retracts. This knocking action shakes off any residual coal particles adhering to the swing plate's surface, achieving secondary cleaning. Furthermore, the ash discharge holes allow dust and fine particles to be discharged through them during the cleaning process, preventing accumulation on the swing plate. This further improves cleaning efficiency, ensures the cleanliness of the drive drum during long-term operation, and achieves swing cleaning.

[0021] Furthermore, the present invention utilizes support springs in conjunction with the swing shafts. Specifically, the ring-shaped array of swing shafts on the support ring and the support springs mounted on the swing shafts provide stable support and elastic restoring force for the swing plate's swing. The support springs elastically contact the inner wall of the swing sleeve, making the swing plate more flexible during swing, enabling it to quickly respond to changes in the belt's operating state. They also provide a stable restoring force when the swing plate returns to its original position, ensuring its proper operation.

[0022] Furthermore, the support column of the present invention can be made of nylon, and the fixed adjustment column is threadedly connected to the adjustment base, allowing the support column length to be flexibly adjusted according to actual needs. By rotating the adjustment column, the position of the support column's contact limit with the swinging end of the swinging plate can be changed, thereby adjusting the swinging angle and range of the swinging plate. This design allows the drive roller to adapt to the operating conditions of the swinging plate under different working conditions, improving the versatility and adaptability of the equipment.

[0023] Furthermore, the connecting frame of the present invention comprises a plurality of connecting arms arranged in an annular array between the support ring and the connecting shaft, providing a stable support structure for the support ring. This hollow structure not only reduces the overall weight but also ensures the stability of the support ring during rotation. This ensures that the connection between the support ring and the connecting shaft is secure and reliable, without deformation or loosening, even when the drive drum rotates at high speeds and bears heavy loads, thus achieving stable support for the connecting frame.

[0024] The fan in the air inlet chamber of the present invention is connected to a centrifugal impeller, and arc-shaped guide vanes are arranged around the centrifugal impeller. The exhaust gaps between the guide vanes guide the airflow, making the airflow generated by the fan more concentrated and stable towards the exhaust nozzle, improving the blowing efficiency and effectiveness of the blowing assembly and enhancing the cleaning ability of the drive drum surface.

[0025] The curved air chamber on the outer wall of the exhaust duct, as well as the internal air duct and auxiliary axial fan, provide directional airflow to the outer ring of the cleaning wheel. As the cleaning brush of the cleaning wheel cleans the swing plate, the airflow from the air chamber further removes any coal particles remaining on the brush. It also promptly blows away dust generated during the cleaning process, preventing it from reattaching to the swing plate or other parts of the drive roller. The main axial fan within the exhaust duct, with its airflow directed away from the roller mechanism, effectively removes dust and debris generated during the cleaning process, maintaining a clean work area and improving the overall cleaning efficiency of the cleaning mechanism.

[0030] The application principle of the present invention is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the present invention provides a drive roller of an anti-slip coal conveyor belt conveyor, comprising: The roller mechanism includes a connecting shaft 1, a connecting frame and a support ring 3. The connecting frame is provided between the connecting shaft 1 and the support ring 3 and is connected to both of them respectively. In the specific implementation process, the connecting shaft 1 is coaxially fixed to the roller drive shaft and connected to the frame. A plurality of cover plate mechanisms are provided in a circular array along the outer wall of the support ring 3, including support columns 12 and swing plates 8; the support columns 12 are vertically connected to the outer wall of the support ring 3; the first end of the swing plate 8 is rotatably connected to the support ring 3. In a specific implementation, the support ring 3 is provided on the swing seat 4, and the second end of the swing plate 8 is in limited contact with the support column 12; an air inlet 25 is provided on the support ring 3 at a position corresponding to each swing plate 8; The cover plate deployment mechanism is provided between the connecting shaft 1 and the support ring 3 and includes an air blowing assembly. The air blowing assembly includes an air inlet chamber 17, a fan is provided inside the air inlet chamber 17, and an exhaust chamber 18 is provided on its side wall and connected thereto. The exhaust chamber 18 is provided with a plurality of exhaust nozzles 19 arranged in an array facing the support ring 3. In the specific implementation process, the cover plate mechanism is suspended and fixed between the support ring 3 and the connecting shaft 1 by a frame (not shown in the figure); The cleaning mechanism is arranged on the outside of the roller mechanism. When the second end of the swing plate 8 is separated from the support column 12 under the action of the cover plate unfolding mechanism, the swing plate 8 contacts the cleaning mechanism and its outer wall is cleaned by the cleaning mechanism.

[0032] The above solution effectively prevents coal dust from depositing on the drive roller, improving the roller's anti-slip performance, thereby reducing equipment wear, extending equipment life, and reducing maintenance costs. Specifically, the swing plates 8 arranged in an annular array on the support ring 3 of the present invention can be adjusted during normal operation to alter the contact angle and area between the drive roller and the belt by adjusting their swing angle. When the coal conveyor belt is under heavy load or under slippery conditions, such as when the belt surface is wet, the position of the swing plates 8 can be adjusted accordingly to increase the friction between them and the belt, ensuring that the drive roller can stably drive the belt and effectively prevent slippage. Furthermore, when anti-slip treatment is required, the cover plate deployment mechanism deploys the swing plates 8 facing the belt at a specific position, allowing them to contact the cleaning brush and clean them. The swing plates 8 are then retracted onto the support ring 3, where they strike against the support ring 3, cleaning the swing plates 8 a second time. Simultaneously, the airflow from the cover plate deployment mechanism assists in blowing dust away, discharging it through the exhaust duct 20.

[0033] In a specific embodiment of the present invention, the support ring 3 is provided with a plurality of swing shafts 5 in an annular array, each swing shaft 5 being provided with a support spring 6. A swing sleeve 7 is provided on the first end of the swing plate 8, which is sleeved onto the swing shafts 5. The support springs 6 are in elastic contact with the inner wall of the swing sleeve 7. In a specific embodiment, the number of support springs 6 is greater than or equal to two. In a specific embodiment, the swing shafts 5 are rotatably mounted on the swing seat 4.

[0034] In the above scheme, the annular array of swing shafts 5 on the support ring 3 and the support springs 6 mounted on these swing shafts 5 provide stable support and elastic restoring force for the swinging of the swing plate 8. The support springs 6 elastically contact the inner wall of the swing sleeve 7, making the swing plate 8 more flexible during its swinging process and able to quickly respond to changes in the belt's operating state. At the same time, they provide a stable restoring force when the swing plate 8 returns to its original position, ensuring its normal operation.

[0035] In a specific embodiment of the present invention, a plurality of protrusions 10 are arranged in an array on each swing plate 8. In a specific implementation, each protrusion 10 can be integrally formed with the swing plate 8, which can save support costs and improve the stability of the entire structure.

[0036] In the above solution, the array of raised portions 10 on the swing plate 8 further enhances the coefficient of friction with the belt. These raised portions 10 dig into the belt surface, particularly at the moment of contact between the belt and the roller, providing additional grip and effectively reducing belt slip on the roller. Whether overcoming static friction during startup or managing varying loads during operation, the raised portions 10 significantly enhance the drive roller's anti-slip capabilities.

[0037] In a specific embodiment of the present invention, a plurality of ash discharge holes 9 are arranged in an array on each swing plate 8 , each protrusion 10 is arranged at the edge of the corresponding ash discharge hole 9 , and all the protrusions 10 and all the ash discharge holes 9 are integrally stamped and bent.

[0038] In the above scheme, the ash discharge holes 9 can discharge most of the coal dust and ash while ensuring friction strength with the belt, preventing accumulation of coal dust and ash. When the swing plate 8 is retracted onto the support ring 3, it will strike against the support ring 3. This striking action shakes off residual coal particles adhering to the surface of the swing plate 8, achieving secondary cleaning. Furthermore, the provision of the ash discharge holes 9 allows dust and fine particles to be discharged through the ash discharge holes 9 during the cleaning process, preventing accumulation on the swing plate 8. This further improves cleaning efficiency and ensures the cleanliness of the drive drum during long-term operation.

[0039] In a specific embodiment of the present invention, an adjustment column 14 is provided on the end of each support column 12 away from the swing plate 8, and an adjustment seat 11 is provided on the support ring 3. The adjustment column 14 and the adjustment seat 11 are threadedly connected.

[0040] In the above solution, support column 12 is made of nylon, and an adjustment column 14, fixed at its end, is threadedly connected to adjustment base 11, allowing the length of support column 12 to be flexibly adjusted according to actual needs. By rotating adjustment column 14, the position of contact between support column 12 and the swing end of swing plate 8 can be changed, thereby adjusting the swing angle and range of swing plate 8. This design allows the drive roller to adapt to the operating conditions of swing plate 8 under different working conditions, improving the versatility and adaptability of the equipment.

[0041] In a specific embodiment of the present invention, a connecting column 13 is provided at the end of each adjusting column 14 , and a plurality of coupling protrusions are arranged in an array on the surface of the connecting column 13 . The supporting column 12 is fixedly connected to the adjusting column 14 through the connecting column 13 .

[0042] In the above solution, the bonding protrusions arranged in the array of protrusions have a higher bonding strength, and it is not easy for the support pillars 12 to fall off from the connecting pillars 13 due to temperature changes.

[0043] In a specific embodiment of the present invention, the support frame is a hollow structure, including a plurality of connecting arms 2 each arranged along the circumferential surface of the connecting shaft 1 .

[0044] In the above solution, the hollowing ratio of the connecting arm 2 structure is greater, and the strength can also be guaranteed.

[0045] In a specific embodiment of the present invention, a centrifugal impeller 16 is connected to the fan in the air inlet chamber 17, and arc-shaped guide vanes 15 are provided in the air inlet chamber 17. The guide vanes 15 are arranged around the centrifugal impeller 16, and exhaust gaps are provided between the guide vanes 15.

[0046] In the above solution, the centrifugal impeller 16 can reduce the axial thickness of the air inlet chamber 17 , making it easier to arrange the air inlet chamber 17 in the axial region of the transmission drum without interfering with the rotation of the support ring 3 .

[0047] In a specific embodiment of the present invention, the cleaning mechanism includes an exhaust duct 20, and at least two groups of cleaning wheels 22 are arranged at the opening of the exhaust duct 20. Each cleaning wheel 22 is driven to rotate by a driving member (such as a motor), and each cleaning wheel 22 is provided with a cleaning brush.

[0048] In the above solution, the specific structure of the cleaning mechanism is limited. When each cleaning wheel 22 rotates under the action of the driving member, the cleaning brush outside the cleaning wheel cleans the outer wall of the swing plate 8.

[0049] In a specific embodiment of the present invention, at least two arc-shaped blowing cavities are provided on the side wall of the exhaust pipe 20, and each cleaning wheel 22 is located in a corresponding blowing cavity. The side wall of each blowing cavity is connected to a blowing pipe 21, and each blowing pipe 21 is provided with a secondary axial flow fan 23. The air outlet direction of each secondary axial flow fan 23 is toward the corresponding blowing cavity and toward the roller mechanism. A main axial flow fan 24 is disposed in the exhaust duct 20 , and the air outlet direction of the main axial flow fan 24 is disposed away from the roller mechanism.

[0050] In the above solution, the secondary axial flow fan 23 and the blowing chamber can dynamically blow air to the cleaning wheel 22, reducing the adhesion of coal powder and coal ash on the surface of the cleaning wheel 22 and preventing secondary pollution to the swing plate 8. The main axial flow fan 24 can quickly exhaust dust in the exhaust pipe 20 to prevent accumulation.

[0051] The working principle of the transmission roller in the present invention is described in detail below: During use, the transmission roller rotates clockwise under the action of the driving member, and the belt contacts the surface of each swing plate 8 to drive the transmission roller. When the swing plate 8 rotates to be opposite to the cover plate unfolding mechanism, the centrifugal impeller 16 will inhale air from the side of the air inlet chamber 17, blow it into the exhaust chamber 18 through one end of the air inlet chamber 17, and then pass through the exhaust nozzle 19 on the exhaust chamber 18 to make the swing plate 8 unfold relatively from the support ring 3. The unfolded swing plate 8 will contact the cleaning wheel 22 and be cleaned under the rotation of the cleaning wheel 22. At the same time, the main axial fan 24 will also assist the swing plate 8 to unfold and separate coal powder or coal ash. The secondary axial fan 23 in the blowing pipe will lift the coal powder on the cleaning wheel 22 and discharge it from the exhaust pipe 20 through the main axial fan 24.

[0052] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
