Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal transportation technology, and in particular to a coal mine transport conveyor belt. Background Technology
[0002] Since its invention in 1795, belt conveyors have undergone more than 200 years of development and have been widely adopted in various industries such as power, metallurgy, coal, chemical, mining, and ports. Especially after the Third Industrial Revolution, the adoption of new materials and technologies ushered in a new era for belt conveyors. Today, whether measured by conveying capacity, transport distance, or economic benefits, it can rival train and automobile transportation, becoming a sector that countries are vying to develop.
[0003] Belt conveyors are characterized by simple structure, large conveying capacity, wide range of conveyed materials, long conveying distance, convenient loading and unloading, high reliability, low freight cost, and high degree of automation. Their advantages are already very obvious, and they are an indispensable key piece of equipment in the national economy.
[0004] However, existing belt conveyors cannot effectively clean and handle loose coal dust during coal mine transportation, which may lead to belt misalignment. Coal dust accumulation at the hub increases the hub's resistance, causing stalling. In severe cases, it may even break the belt or damage the drive equipment. When coal dust reaches the lower explosive limit in air, it may ignite upon contact with a spark, causing an explosion and safety accident. If coal dust is not treated for a long time, it will pollute the working environment. Coal mine workers working in a polluted environment for a long time may inhale coal dust, leading to respiratory diseases. When coal mine workers inspect the equipment, if they get too close to the equipment, a misaligned belt may snag their clothing and cause dragging, creating a hazard. Therefore, this application provides a coal mine transportation conveyor belt to meet the needs. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a coal mine transport conveyor belt to solve the problem that existing conveyors cannot effectively clean coal dust from the hub and cannot effectively collect coal dust.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A coal mine conveyor belt includes a conveyor support. A hub support plate is threaded through the upper surface of the conveyor support. A main hub is rotatably connected to the upper surface of the hub support plate, and a secondary hub is rotatably connected to the upper surface of the hub support plate.

[0009] Optionally, a starting bracket is inserted into one side of the transport bracket, a starting shaft seat is threaded through the upper surface of the starting bracket, a starting motor is rotatably connected to one side of the starting shaft seat, and a starting belt shaft is rotatably connected to one side of the starting motor.
[0010] Optionally, a belt shaft plate is threaded through one side of the transport bracket, and a belt shaft is rotatably connected to the upper surface of the belt shaft plate. The number of belt shaft plates is two.
[0011] Optionally, a coal powder collecting plate is threaded through one side of the transport bracket, a coal powder collecting frame is fixedly connected to the lower surface of the coal powder collecting plate, a coal powder collecting box is rotatably connected to one side of the coal powder collecting frame, and a pull rod is provided on one side of the coal powder collecting box.
[0012] Optionally, the upper surface of the coal powder collection plate is provided with a coal powder filter, a filter fan is provided on one side of the coal powder filter, a filter ring is provided inside the coal powder filter, a pulse vibrator is provided on the lower surface of the filter ring, a filter cover is provided on the upper surface of the coal powder filter, a collection chamber is provided on one side of the coal powder filter, and a drain outlet is provided on the lower surface of the coal powder filter.
[0013] Optionally, a limiting hole is provided on one side of the baffle shaft seat, and a limiting hole is provided on one side of the conveyor belt baffle. The baffle shaft seat limits the conveyor belt baffle through the limiting hole.
[0014] Optionally, a sliding groove is provided on one side of the pulverized coal collecting plate, a sliding groove is provided on one side of the pulverized coal collecting frame, and a sliding block is provided on one side of the pulverized coal collecting box.
[0015] Optionally, a coal powder collection pipe is inserted into one side of the collection chamber, and the collection chamber is connected to the coal powder collection box through the coal powder collection pipe.
[0016] Optionally, a limiting rod is provided on one side of the pulverized coal collecting frame, and a limiting groove is provided on the sliding block of the pulverized coal collecting box. The pulverized coal collecting frame limits the pulverized coal collecting box through the limiting rod.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] In the above scheme, the starting motor rotates, driving the starting belt shaft, which in turn drives the conveyor belt. The conveyor belt then rotates the main and auxiliary hubs, which in turn drive the hub brushes. The rotating conveyor belt baffles, with their limiting positions relative to the baffle shaft seats, address the issue of coal dust adhering to the hubs during coal mine transportation. Existing equipment cannot effectively clean this adhering coal dust, potentially causing conveyor belt misalignment. Coal dust accumulation at the hubs increases resistance, leading to stalling and, in severe cases, belt breakage or damage to the drive equipment. Furthermore, coal dust reaching its lower explosive limit in air can ignite upon contact with a spark, causing an explosion and safety hazard. Untreated coal dust pollutes the working environment over time. Miners who inhale coal dust for extended periods may develop respiratory illnesses. During maintenance and repair of the conveyor belt, if the belt shifts, it could snag on miners, causing dragging and posing a danger. This reduces the belt's lifespan, decreases transport efficiency, and harms miners' health. This equipment features a hub brush under the hub to clean coal dust adhering to it. The cleaned coal dust falls into a collection box, preventing belt shifting caused by long-term coal dust accumulation. Collecting the coal dust also prevents explosions from sparks and contaminates the working environment. Conveyor belt baffles further prevent the belt from snagging on miners during inspections and patrols, significantly increasing miners' safety, extending belt lifespan, and improving transport efficiency.
[0019] Coal powder is drawn into the coal powder collection pipe from the coal powder collection box. A rotating filter fan then draws the coal powder from the collection chamber into the coal powder collector. The coal powder is adsorbed by the filter rings, and a pulse vibrator shakes off the coal powder adhering to the filter rings. The shaken-off coal powder is collected in the coal powder collection box. During coal powder collection, due to the working environment of coal mines, the amount of coal powder can be excessive. Over time, coal powder adhering to the filter rings can cause filter clogging. If left untreated, this can significantly weaken the suction, affecting subsequent coal powder collection efficiency and impurities. Coal dust may get stuck inside the fan, causing abnormal noises and, in severe cases, malfunctions, reducing the efficiency of coal dust collection and shortening the equipment's lifespan. This equipment uses a pulse vibrator to shake the coal dust adhering to the filter rings into the coal dust collection box. Prolonged coal dust accumulation can cause the collection box to overflow. When overflowing, the full collection box can be removed, and another collection box can continue collecting coal dust, preventing overflow and coal dust scattering. This significantly increases the efficiency of coal dust collection and extends the equipment's lifespan. Attached Figure Description

[0036] like Figures 2 to 5 As shown, an embodiment of this utility model provides a coal mine transport conveyor belt, including a transport support 1. A hub support plate 2 is threaded through the upper surface of the transport support 1. A main hub 3 is rotatably connected to the upper surface of the hub support plate 2, and a secondary hub 4 is rotatably connected to the upper surface of the hub support plate 2. A hub brush 5 is rotatably connected to one side of the main hub 3, and a secondary hub brush 6 is rotatably connected to one side of the secondary hub 4. A transport belt 7 is rotatably connected to the upper surface of the main hub 3. A coal dust collection box 8 is provided on the lower surface of the hub support plate 2. A coal dust collection pipe 9 is inserted into the lower surface of the coal dust collection box 8. An end support plate 10 is inserted into one side of the transport support 1. An end bearing seat 11 is threaded through the upper surface of the end support plate 10, and an end belt shaft 12 is rotatably connected to one side of the end bearing seat 11. The lower surface of the transport support 1 is provided with a pad 13. A baffle shaft seat 14 is provided on one side of the transport support 1. A limit hole is opened on one side of the baffle shaft seat 14. A limit hole is opened on one side of the conveyor belt baffle 15. The baffle shaft seat 14 limits the conveyor belt baffle 15 through the limit hole. The conveyor belt baffle 15 is rotatably connected to one side of the baffle shaft seat 14. A starting support 16 is inserted into one side of the transport support 1. A starting shaft seat 17 is threaded through the upper surface of the starting support 16. A starting motor 18 is rotatably connected to one side of the starting shaft seat 17. A starting belt shaft 19 is rotatably connected to one side of the starting motor 18. A belt shaft plate 20 is threaded through one side of the transport support 1. A belt shaft 21 is rotatably connected to the upper surface of the belt shaft plate 20. There are two belt shaft plates 20.
[0037] The starting motor 18 rotates, driving the starting belt shaft 19 to rotate. The starting belt shaft 10 rotates, driving the conveyor belt 7 to rotate. The conveyor belt 7 rotates, driving the main hub 3 and the auxiliary hub 4 to rotate. The rotation of the main hub 3 and the auxiliary hub 4 drives the hub brush 5 and the auxiliary hub brush 6 to rotate. By rotating the conveyor belt baffle 15 and limiting the position of the conveyor belt baffle 15 against the baffle shaft seat 14, the conveyor belt 7 can be deviated. Coal dust accumulates at the hub, increasing the resistance and causing the hub to stall. In severe cases, this may lead to belt breakage or damage to the drive equipment. When the coal dust reaches the lower explosive limit in air, it may explode upon contact with a spark, causing a safety accident. If the coal dust is not treated for a long time, it will pollute the operation. The environment is complex. Long-term inhalation of coal dust by coal miners can lead to respiratory illnesses. During maintenance and repair of the conveyor belt, if the belt shifts, it could snag on miners, causing dragging and posing a danger. This reduces the belt's lifespan, decreases transport efficiency, and harms miners' health. This equipment features a hub brush 5 under the hub to clean coal dust adhering to it. The cleaned coal dust falls into the coal dust collection box 8, preventing belt shifting caused by long-term coal dust accumulation. Collecting the coal dust also prevents explosions from sparks and avoids environmental pollution. The conveyor belt baffle 15 prevents the belt from snagging on miners during inspections and patrols, significantly increasing the safety of the working environment, extending belt lifespan, and improving transport efficiency.
[0038] like Figure 3 and Figures 6 to 7As shown, a coal dust collection box 8 is provided on the lower surface of the hub support plate 2, and a coal dust collection pipe 9 is inserted into the lower surface of the coal dust collection box 8. A coal dust collection plate 22 is threaded through one side of the transport bracket 1. A sliding groove is provided on one side of the coal dust collection plate 22. A sliding groove is provided on one side of the coal dust collection frame 23. A sliding block is provided on one side of the coal dust collection box 24. A coal dust collection frame 23 is fixedly connected to the lower surface of the coal dust collection plate 22. A limiting rod is provided on one side of the coal dust collection frame 23. A limiting groove is provided on the sliding block of the coal dust collection box 24. The coal dust collection frame 23 limits the coal dust collection box 24 through the limiting rod. A rotatable coal powder collection box 24 is connected to the coal powder collection box 24. A pull rod 25 is provided on one side of the coal powder collection plate 22. A coal powder filter 26 is provided on the upper surface of the coal powder collection plate 22. A drain port is provided on the lower surface of the coal powder filter 26. A filter fan 27 is provided on one side of the coal powder filter 26. A filter ring 28 is provided inside the coal powder filter 26. A pulse vibrator 29 is provided on the lower surface of the filter ring 28. A filter cover plate 30 is provided on the upper surface of the coal powder filter 26. A collection chamber 31 is provided on one side of the coal powder filter 26. A coal powder collection pipe 9 is inserted into one side of the collection chamber 31. The collection chamber 31 is connected to the coal powder collection box 8 through the coal powder collection pipe 9.
[0039] The coal dust in the coal dust collection box 8 is drawn into the coal dust collection pipe 9. The coal dust in the collection chamber 31 is then drawn into the coal dust collector 26 by the rotation of the filter fan 27. The coal dust is then adsorbed by the filter ring 28, and the coal dust adhering to the filter ring 28 is shaken off by the vibration of the pulse vibrator 29. The shaken-off coal dust is collected in the coal dust collection box 24. During coal dust collection, due to the working environment of coal mines, the amount of coal dust can be excessive. Over time, coal dust adhering to the filter ring 28 can cause filter port blockage. If left untreated, this can lead to a significant weakening of suction, affecting subsequent coal dust collection efficiency. Impurities may get stuck inside the blower, causing abnormal noises and, in severe cases, equipment malfunction, reducing the efficiency of coal dust collection and shortening the equipment's lifespan. This equipment uses a pulse vibrator 29 to shake the coal dust adhering to the filter ring 28 into the coal dust collection box 24. Prolonged coal dust accumulation can cause the coal dust collection box 24 to overflow. When overflowing, the full coal dust collection box 24 can be removed, and another coal dust collection box 24 can continue collecting coal dust, preventing overflowing and coal dust scattering. This significantly increases the efficiency of coal dust collection and extends the equipment's lifespan.
[0040] The working principle of the technical solution provided by this utility model is as follows: The starting motor 18 rotates, driving the starting belt shaft 19 to rotate. The starting belt shaft 10 rotates, driving the conveyor belt 7 to rotate. The conveyor belt 7 rotates, driving the main hub 3 and the auxiliary hub 4 to rotate. The main hub 3 and the auxiliary hub 4 rotate, driving the hub brush 5 and the auxiliary hub 6 to rotate. By rotating the conveyor belt baffle 15 and limiting the conveyor belt baffle 15 to the baffle shaft seat 14, the coal powder in the coal powder collection box 8 is sucked into the coal powder collection pipe 9. The filter fan 27 rotates, sucking the coal powder in the collection bin 31 into the coal powder collector 26. The filter ring 28 adsorbs the coal powder. The pulse vibrator 29 vibrates, shaking off the coal powder adhering to the filter ring 28. The shaken coal powder is collected in the coal powder collection box 24.
[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
