Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a bulk cargo dust-proof suspended conveying device. Background Technology

[0002] Suspended conveyor systems are mechanized equipment that enables efficient loading, unloading, and short-distance transportation of materials through suspension. They are widely used in ports, warehouses, factories, and other settings. By integrating vertical lifting and horizontal transportation functions, these devices significantly shorten the material flow path and are a key node for improving efficiency in modern logistics systems.

[0003] For example, Chinese patent CN117302880B discloses a suspended conveying device. In this device, the brake triggering device is designed to mesh with a pin shaft and a toothed disc. During the rotation of the toothed disc, the rotation torque is kept stable, so that the brake device can be reliably triggered. This effectively avoids the problem of collision between adjacent conveying trolleys caused by the brake device failing to start.

[0004] When existing overhead conveyor systems are used to load and transport bulk cargo such as coal and ore in ports, they are affected by wind in the port environment. The wind blows the dust attached to the surface of the ore and coal, which causes serious dust pollution. This not only affects the ecological environment around the port, but also increases the loss of raw materials such as coal and ore during transportation. Furthermore, dust can enter the interior of the overhead conveyor system and cause the moving parts to jam, which in turn increases the failure rate of the overhead conveyor system.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 This invention provides a technical solution:

[0033] A bulk cargo dust-proof suspended conveyor includes a guide rail 15 and a hopper 11. Guide seats 12 are fixedly connected to the front and rear sides of the upper outer surface of the hopper 11. A fixed seat 21 is fixedly connected between two sets of guide seats 12. A sealing assembly is provided inside the fixed seat 21. The sealing assembly includes a receiving groove 26 embedded in the inner side of the fixed seat 21. A coil spring 24 is fixedly connected to the inner surface of the receiving groove 26. A roller 25 is rotatably connected to the receiving groove 26 through the coil spring 24. A sealing curtain 28 is wound around the outer surface of the roller 25. A guide groove 23 is embedded in the inner side of the guide seat 12. A drive wheel 27 is slidably connected to the inner side of the guide groove 23. A traction rod 29 is fixedly connected through the inner side of the drive wheel 27. The end of the sealing curtain 28 away from the roller 25 is fixedly connected to the traction rod 29.

[0034] The inner surface of the guide groove 23 is fixedly connected to the limiting plate 30, and the outer surface of the limiting plate 30 is fixedly connected to the telescopic rod 31. The end of the telescopic rod 31 away from the limiting plate 30 is fixedly connected to the drive wheel 27. The number of the sealing curtain 28, the traction rod 29 and the storage groove 26 are all two sets and are symmetrically distributed. The sealing curtain 28 is made of flexible material. The sealing curtain 28 is located on the upper side of the hopper 11. The sealing assembly is used to cover and seal the upper side of the hopper 11.

[0035] By adopting the above technical solution, when conveying bulk materials such as ore and coal through a suspended conveyor, a sealing component is installed to reduce dust caused by wind in the environment. When the hopper 11 is full of bulk materials, the operator activates the telescopic rod 31. The guide groove 23 is fixedly supported by the limiting plate 30. The telescopic rod 31 pushes the drive wheel 27. The guide groove 23 can guide the drive wheel 27 to move smoothly. During the movement of the drive wheel 27, it drives the traction rod 29 to move synchronously. During the movement of the traction rod 29, it pulls the sealing curtain 28. The receiving groove 26 supports the rotation of the roller 25 through the coil spring 24. The sealing curtain 28 is wound around the outside of the roller 25. When pulled by an external force, the coil spring 24 will produce elastic deformation, causing the roller 25 to rotate. The rotation of the roller 25 can release the sealing curtain 28 on its surface, thereby enabling... The sealing curtain 28 covers the upper surface of the hopper 11. At the same time, the elasticity of the coil spring 24 keeps the sealing curtain 28 under a certain tension, keeping the outer surface of the sealing plate flat. When the drive wheel 27 drives the traction rod 29 to move to the side of the receiving groove 26, the roller 25 rotates under the elasticity of the coil spring 24, thereby winding the sealing curtain 28 around the outer surface of the roller 25. The two sets of sealing curtains 28 and rollers 25 are symmetrically distributed on both sides of the fixed base 21, which can simultaneously cover the upper side of the hopper 11, thereby effectively improving the covering speed of the sealing curtain 28. By setting the sealing component to cover the upper side of the hopper 11 with the sealing curtain 28, the upper end of the hopper 11 can be sealed, thereby reducing the probability of the bulk materials inside the hopper 11 spilling during the suspended conveying process to a certain extent. At the same time, it can also effectively reduce the risk of dust caused by the wind blowing the bulk materials, thereby further improving the environmental protection effect of the suspended conveying device.

[0036] Specifically, such as Figure 4 , Figure 7 and Figure 8 As shown, a cleaning assembly is provided inside the guide groove 23. The cleaning assembly includes a support plate 33 fixedly connected to the outer surface of the drive rod 22. The support plate 33 has an L-shaped structure. A scraper 34 is fixedly connected to the lower outer surface of the support plate 33. The lower outer surface of the scraper 34 slides in contact with the lower end of the guide groove 23. The scraper 34 is inclined and is made of wear-resistant elastic material.

[0037] By adopting the above technical solution, during the bulk loading process, some bulk cargo may accidentally enter the guide groove 23. In order to avoid the bulk cargo from causing jamming of the drive wheel 27, a cleaning component is set up. The traction rod 29 is fixedly supported by the support plate 33. During the movement of the traction rod 29, the support plate 33 will move synchronously. The support plate 33 will drive the scraper 34 to slide into contact with the inner wall of the guide groove 23. The scraper 34 is inclined and moves away from the fixed seat 21, which will discharge the bulk cargo in the guide groove 23 into the hopper 11. This can reduce the residue of foreign objects in the guide groove 23, thereby effectively reducing the risk of the bulk cargo causing jamming of the drive wheel 27, and further improving the stability of the sealing component during operation.

[0038] Specifically, such as Figure 4 and Figure 7 As shown, a bladder 32 is fixedly connected to the outer surface of the support plate 33 away from the drive wheel 27. The end of the bladder 32 away from the support plate 33 is fixedly connected to the inner surface of the guide groove 23. An air inlet pipe 36 is fixedly connected to the outer surface of the bladder 32, and the air inlet pipe 36 extends to the outside of the hopper 11. An air outlet pipe 35 is fixedly connected to the lower outer surface of the bladder 32. There are two sets of bladders 32, which are symmetrically distributed on both sides of the fixed seat 21. The cleaning component is used to clean the inside of the guide groove 23.

[0039] By adopting the above technical solution, when the guide wheel 38 moves away from the fixed seat 21, the support plate 33 will cooperate with the guide groove 23 to squeeze the bladder 32. At this time, the gas inside the bladder 32 will be discharged outward through the air outlet pipe 35. The discharged gas can blow away the impurities inside the guide groove 23, thereby effectively reducing the residue of foreign objects inside the guide groove 23, and further improving the stability of the drive wheel 27 during movement. When the drive wheel 27 and the support plate 33 move in opposite directions, the support plate 33 will stretch the bladder 32. At this time, the external gas enters the bladder 32 through the air inlet pipe 36, thereby inflating the bladder 32.

[0040] Specifically, such as Figure 1 and Figure 5 As shown, a traction assembly is provided on the outer side of the guide rail 15. The traction assembly includes a conveyor chain 16 that slides in contact with the upper outer surface of the guide rail 15. The guide rail 15 has an I-shaped structure. Guide wheels 38 are symmetrically arranged on the inner surface of the guide rail 15. The lower side of the outer surface of the guide wheel 38 is in rotatable contact with the guide rail 15. A movable rod 39 is rotatably connected to the inner surface of the guide wheel 38. A baffle 41 is fixedly connected to the outer end of the movable rod 39 away from the guide rail 15.

[0041] The outer surface of the movable rod 39 is rotatably connected to a rotating sleeve 40, the outer surface of the rotating sleeve 40 is fixedly connected to a fixing frame 17, the outer surface of the conveyor chain 16 is fixedly connected to a connecting plate 37, the outer surface of the connecting plate 37 away from the conveyor chain 16 is fixedly connected to the fixing frame 17, the fixing frame 17 has a Y-shaped structure, and the drive wheel 27 is made of wear-resistant material.

[0042] The outer surface of the fixed frame 17 is rotatably connected to a fixed pin 19, and the outer surface of the fixed pin 19 is rotatably connected to a movable frame 18. The movable frame 18 has a U-shaped structure, and a connecting frame 20 is fixedly connected to the lower outer surface of the movable frame 18. The lower outer surface of the connecting frame 20 is fixedly connected to the fixed seat 21. The connecting frame 20 is triangular. The traction component is used to drive the hopper 11 to move along the lower side of the guide rail 15.

[0043] The number of drive wheels 27 and hoppers 11 are several sets and are equidistantly distributed on the lower side of guide rail 15. The conveyor chain 16 is connected to the power output module of the conveying device. The power output module drives the conveyor chain 16 to move at a constant speed through motor 13 and gears. The conveyor chain 16 is used to drive the drive wheels 27 to move along the inner side of guide rail 15.

[0044] By adopting the above technical solution, the fixed frame 17 is rotatably supported by the rotating sleeve 40 on the movable rod 39, and the movable rod 39 is rotatably supported by the guide wheel 38, so that the two sets of guide wheels 38 can move smoothly inside the guide rail 15. The fixed frame 17 has a Y-shaped structure, which allows the two sets of guide wheels 38 to be symmetrically distributed. When the suspended conveyor is working, its power output module will drive the conveyor chain 16 to move through the motor 13 and gears. The conveyor chain 16 can play a certain guiding role by contacting the upper surface of the guide rail 15, so that the conveyor chain 16 can move smoothly. During the movement, the conveyor chain 16 drives the fixed frame 17 to move synchronously through the connecting plate 37, and the fixed frame 17 drives the guide wheel 38 to move inside the guide rail 15. The guide wheel 38 can distribute the weight of the fixed frame 17. When moving inside the guide rail 15, the fixed frame 17 drives the fixed pin 19 and the movable frame 18 to move synchronously. Then, the movable frame 18 drives the connecting frame 20 and the fixed seat 21 to move synchronously, thereby traction and support the hopper 11 and moving the hopper 11 to the predetermined position. By setting several sets of guide wheels 38 and the hopper 11, bulk materials can be continuously transported, thereby improving the transport efficiency of bulk materials to a certain extent. The fixed frame 17 and the movable frame 18 are rotatably connected by the fixed pin 19. When the hopper 11 is blown by the wind in the environment, the hopper 11 and the connecting frame 20 will deflect at a certain angle, thereby buffering the wind force on the hopper 11 and reducing the load on the guide rail 15 in the horizontal direction to a certain extent, thereby improving the safety and stability of the suspended conveyor during operation.

[0045] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a storage component is provided inside the hopper 11. The storage component includes a sealing seat 42 that is fixedly connected to the inner surface of the hopper 11. The outer surface of the sealing seat 42 is arc-shaped. There are two sets of sealing seats 42 that are symmetrically distributed. The upper end of the hopper 11 is open.

[0046] A motor 13 is fixedly connected to the outer surface of the front end of the hopper 11. A drive rod 22 is fixedly connected to the rear end of the output shaft of the motor 13. A hopper door 14 is fixedly connected to the outer surface of the drive rod 22. The outer surface of the hopper door 14 is in contact with the sealing seat 42. The storage component is used for loading and unloading bulk materials.

[0047] By adopting the above technical solution, when loading bulk cargo, the output shaft of motor 13 drives the drive rod 22 to rotate. The drive rod 22 drives the hopper door 14 to fit against the outer surface of the sealing seat 42. The hopper door 14, in conjunction with the sealing seat 42, can seal the gap between the hopper 11 and the hopper door 14, thereby effectively reducing the probability of leakage during bulk cargo transportation. This allows the bulk cargo to be loaded into the hopper 11. After the hopper 11 has transported the bulk cargo to the designated position, the motor 13 is controlled to rotate in the opposite direction. The output shaft of motor 13 drives the hopper door 14 to flip downward through the drive rod 22. Then, the bulk cargo inside the hopper 11 is discharged outward along the surface of the hopper door 14. The surface of the sealing seat 42 is arc-shaped, which can guide the bulk cargo to a certain extent, thereby making the discharge of bulk cargo smoother and further improving the conveying efficiency of the bulk cargo suspension conveyor.

[0048] Working Principle: When the suspended conveyor is in operation, the drive rod 22 drives the hopper door 14 to fit against the outer surface of the sealing seat 42 to seal the hopper 11. Bulk materials are then loaded into the hopper 11. The telescopic rod 31 then pushes the drive wheel 27, which in turn drives the traction rod 29. The traction rod 29 pulls the sealing curtain 28, allowing it to cover the upper surface of the hopper 11. The traction rod 29 also drives the support plate 33 to move synchronously. The support plate 33 causes the scraper 34 to slide against the inner wall of the guide groove 23. During the movement of the scraper 34, the bulk materials inside the guide groove 23 are discharged into the hopper 11, reducing the residue of foreign objects inside the guide groove 23. The support plate 33 works in conjunction with the guide groove 23 to... The bladder 32 is compressed, and the discharged gas can blow away impurities inside the guide groove 23, thereby effectively reducing the residue of foreign objects inside the guide groove 23. The power output module drives the conveyor chain 16 to move through the motor 13 and gears. During the movement, the conveyor chain 16 drives the fixed frame 17 to move synchronously through the connecting plate 37. The fixed frame 17 drives the guide wheel 38 to move inside the guide rail 15. The guide wheel 38 can distribute the weight of the fixed frame 17. The movable frame 18 drives the connecting frame 20 and the fixed seat 21 to move synchronously, thereby pulling and supporting the hopper 11, thus moving the hopper 11 to the predetermined position. Then, the drive rod 22 drives the hopper door 14 to flip downward, and then the bulk material inside the hopper 11 is discharged outward along the surface of the hopper door 14, thereby completing the rapid transportation of bulk materials.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
