Description

Technical Field

[0001] This invention relates to the field of plowing equipment technology, and in particular to a dust suppression device for the unloading hopper of a plowing equipment. Background Technology

[0002] Belt conveyors are commonly used material conveying equipment that can transport many types of solid bulk materials, such as various ores and coal. Belt conveyors have advantages such as high conveying efficiency, strong conveying capacity, and stable operation. In existing technology, the conveyor belt transports bulk materials to the top of the storage silo, and a plow installed on the conveyor belt discharges the material from the conveyor belt through the plow discharge hopper into the storage silo below.

[0003] Currently, plow discharge hoppers do not have dust suppression structures. Therefore, when material falls into the hopper, gravity causes a temporary material curtain to form, resulting in dust drift. This dust can then be flushed out of the hopper and dispersed into the environment, causing pollution. Furthermore, the drifting dust accumulates on external equipment, causing corrosion and damage, and affecting normal operation. Additionally, maintenance personnel are easily exposed to dusty air during equipment inspections, threatening their health. Therefore, a dust suppression device for plow discharge hoppers is proposed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a dust suppression device for the unloading hopper of a plow, which can solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression device for a plow unloading hopper, comprising two support plates, each with a support leg fixedly connected to its lower end; a transmission belt is provided on one side of the two support plates via a transmission shaft; a motor is fixedly connected to one of the support plates, the output end of the motor being fixedly connected to the transmission shaft; an mounting plate is fixedly connected between the two support plates, a connecting rod is fixedly connected to the mounting plate, and a plow body is fixedly connected to the connecting rod; a hopper is fixedly connected to one side of the two support plates facing away from each other, and a dust suppression device is provided inside the hopper.

[0006] Preferably, the lower end of each hopper is open, and each hopper is provided with a feed chute and a discharge chute. An inclined screening plate is fixedly connected inside the hopper.

[0007] Preferably, the dust suppression device includes a first dust suppression plate, which is fixedly connected inside the hopper. The first dust suppression plate is arc-shaped, and through slots are respectively opened on both sides of the first dust suppression plate. Two support blocks are fixedly connected inside the hopper, and a fixed shaft is fixedly connected to each of the two support blocks. A second dust suppression plate is rotatably connected to each of the two fixed shafts, and the two second dust suppression plates are arranged in a V-shape.

[0008] Preferably, a torsion spring is provided on each of the two fixed shafts, and the two torsion arms of the torsion spring are fixedly connected to the second dust suppression plate and the fixed shaft respectively.

[0009] Preferably, a dustproof curtain is rotatably connected inside the feed trough.

[0010] Preferably, the hopper has two auxiliary plates fixedly connected inside, each of which has a sliding rod connected to it. The end of the sliding rod near the screening plate is fixedly connected to a striking block, and the end of the sliding rod away from the striking block contacts a second dust suppression plate. An arc-shaped protrusion is fixedly connected to one end of the second dust suppression plate.

[0011] Preferably, the plow body is triangular, and guide grooves are provided on both sides of the plow body, and the plow body is in contact with the surface of the conveyor belt.

[0012] Preferably, dustproof plates are fixedly connected to both sides of the plow body.

[0013] Preferably, a return spring is movably sleeved on the moving rod, and the two ends of the return spring are fixedly connected to the moving rod and the auxiliary plate, respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The material discharge hopper dust suppression device of the plow feeder allows the material to gradually flow into the two second dust suppression plates through the arc-shaped surface and through groove of the first dust suppression plate. When the weight of the accumulated material exceeds the load-bearing capacity of the second dust suppression plate, the two second dust suppression plates rotate in opposite directions, thus causing the material to continue to fall to the bottom of the hopper. After the material has fallen, the second dust suppression plate returns to its original position under the elasticity of the torsion spring, thus sealing the hopper and preventing dust from rising back up. This prevents dust from polluting external equipment and the environment. At the same time, the first dust suppression plate is arc-shaped and the two second dust suppression plates are set in a V-shape, thus forming a dustproof cavity between the first and second dust suppression plates. Therefore, the dust generated during the falling process is blocked inside the cavity, which can effectively prevent dust from floating. This prevents dust from accumulating on external equipment and prevents dust from floating in the air and affecting air quality. This ensures that the inspectors will not suffer physical injury due to poor air quality when inspecting the equipment, thus preventing the induction of diseases.

[0016] (2) When the second dust suppression plate rotates, the convex block rotates at the same time. The rotation of the convex block pushes the moving rod to move upward, so that the striking block strikes the screening plate, thereby causing the screening plate to vibrate. Therefore, the dust adhering to the screening plate can be effectively cleaned, and the dust can be prevented from clogging the screening holes of the screening plate, thus ensuring the normal screening of materials.

[0017] (3) The dust suppression device of the plow unloading funnel is equipped with a reset spring. Therefore, when the second dust suppression plate is reset, the protrusion no longer blocks the moving rod. Then the reset spring drives the moving rod and the striking block to reset. Therefore, the protrusion can lift the moving rod again when it rotates next time, thus ensuring that the striking block can continuously strike the screening plate.

[0018] (4) The dust suppression device of the plow unloading hopper, through the dustproof plate, plays a preliminary dustproof effect, avoids the material on the conveyor belt from turning over during the diversion process of the plow body, thus avoiding the dust from being stirred up and falling off the conveyor belt, thus ensuring the normal diversion and unloading of the material.

[0019] (5) When the material on the conveyor belt is diverted by the plow body, the material enters the hopper through the feed chute and falls onto the screening plate. At this time, the material slides along the inclined surface of the screening plate. Therefore, the smaller particles fall through the screening plate to the bottom of the hopper, while the larger particles are blocked on the screening plate and roll towards the discharge chute through its inclined surface, thus flowing out from the inside of the hopper. This allows the material to be screened during the unloading process, thus preventing unevenly sized materials from entering the next stage at the same time, thereby ensuring the subsequent use or processing effect.

[0020] (6) The dust suppression device of the plow unloading hopper is equipped with a dust curtain. When the material is guided into the feed trough through the plow body, the dust curtain rotates due to the influence of the material, thus opening the feed trough and allowing the material to enter the hopper normally. When the material stops feeding, the dust curtain resets by its own gravity, thus sealing the feed trough and effectively preventing dust from drifting, thus ensuring that the environment around the equipment is not polluted.

[0030] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0031] Please see Figure 1-7 The present invention provides a technical solution: a dust suppression device for a plow unloading hopper, comprising two support plates 1, with support legs 2 fixedly connected to the lower ends of both support plates 1, a transmission belt 3 provided on the opposite side of the two support plates 1 via a transmission shaft, a motor 4 fixedly connected to one of the support plates 1, the output end of the motor 4 fixedly connected to the transmission shaft, an mounting plate 5 fixedly connected between the two support plates 1, a connecting rod 6 fixedly connected to the mounting plate 5, a plow body 7 fixedly connected to the connecting rod 6, and a hopper 8 fixedly connected to the opposite side of the two support plates 1, with a dust suppression device provided inside the hopper 8;

[0032] When the output end of motor 4 rotates, it drives the conveyor belt 3 through the drive shaft, thus the conveyor belt 3 transports the material.

[0033] Among them, the plow body 7 is triangular, and guide grooves 25 are provided on both sides of the plow body 7. The plow body 7 is in contact with the surface of the conveyor belt 3.

[0034] The plow body 7 thus diverts the material on the conveyor belt 3, allowing it to flow into the two hoppers 8 through the guide channel 25, and then into the external equipment through the hoppers 8.

[0035] Furthermore, dustproof plates 9 are fixedly connected to both sides of the plow body 7;

[0036] The dustproof plate 9 provides initial dust protection, preventing the material on the conveyor belt 3 from turning over during the diversion process by the plow body 7. This avoids dust from being stirred up and falling off the conveyor belt 3, thus ensuring the normal diversion and unloading of materials.

[0037] Furthermore, the lower ends of the hoppers 8 are all open, and each hopper 8 is provided with a feed chute 10 and a discharge chute 13. An inclined screening plate 12 is fixedly connected inside the hopper 8.

[0038] When the material on the conveyor belt 3 is diverted by the plow body 7, the material enters the hopper 8 through the feed chute 10 and falls onto the screening plate 12. At this time, with the inclined surface of the screening plate 12, the material slides along its inclined surface. Therefore, the smaller particles fall through the screening plate 12 to the bottom of the hopper 8, while the larger particles are blocked on the screening plate 12 and roll towards the discharge chute 13 through its inclined surface, thus flowing out from the inside of the hopper 8. This allows the material to be screened during the unloading process, thus preventing unevenly sized materials from entering the next stage at the same time, thereby ensuring the subsequent use or processing effect.

[0039] The feed trough 10 is rotatably connected to a dustproof curtain 11.

[0040] With the dustproof curtain 11 in place, when the material is guided into the feed trough 10 through the plow body 7, the dustproof curtain 11 rotates due to the material's intervention, thus opening the feed trough 10 and allowing the material to enter the hopper 8 normally. When the material stops feeding, the dustproof curtain 11 resets by its own gravity, thus sealing the feed trough 10 and effectively preventing dust from drifting, thereby ensuring that the environment around the equipment is not polluted.

[0041] Furthermore, the dust suppression device includes a first dust suppression plate 14, which is fixedly connected to the inside of the hopper 8. The first dust suppression plate 14 is arc-shaped, and through slots 24 are respectively opened on both sides of the first dust suppression plate 14. Two support blocks 15 are fixedly connected to the inside of the hopper 8. A fixed shaft 16 is fixedly connected to each of the two support blocks 15. A second dust suppression plate 17 is rotatably connected to each of the two fixed shafts 16. The two second dust suppression plates 17 are arranged in a V-shape.

[0042] Among them, torsion springs 18 are respectively installed on the two fixed shafts 16, and the two torsion arms of the torsion springs 18 are respectively fixedly connected to the second dust suppression plate 17 and the fixed shafts 16.

[0043] When material falls through the screening plate 12 into the hopper 8, it gradually flows through the arc-shaped surface of the first dust suppression plate 14 and the through groove 24 onto the two second dust suppression plates 17. When the weight of the accumulated material exceeds the load-bearing capacity of the second dust suppression plates 17, the two second dust suppression plates 17 rotate in opposite directions, causing the material to continue falling below the hopper 8. After the material has finished falling, the second dust suppression plates 17 return to their original position under the elasticity of the torsion spring 18, thus sealing the hopper 8 and preventing dust from flowing back up, thereby preventing dust from causing damage to external equipment and the environment. The system effectively prevents pollution by using an arc-shaped first dust suppression plate 14 and two V-shaped second dust suppression plates 17. This creates a dustproof cavity between the first and second dust suppression plates 14 and 17, trapping dust generated during material drop within the cavity and preventing dust from drifting. This also prevents dust accumulation on external equipment and avoids dust affecting air quality. Consequently, it ensures that inspectors will not suffer health damage due to poor air quality when checking equipment, thus preventing the onset of diseases.

[0044] Furthermore, two auxiliary plates 19 are fixedly connected inside the hopper 8. Each auxiliary plate 19 is slidably connected with a moving rod 20. The end of the moving rod 20 near the screening plate 12 is fixedly connected with a striking block 21. The end of the moving rod 20 away from the striking block 21 contacts the second dust suppression plate 17. An arc-shaped protrusion 23 is fixedly connected to one end of the second dust suppression plate 17.

[0045] Among them, a return spring 22 is movably sleeved on the moving rod 20, and the two ends of the return spring 22 are fixedly connected to the moving rod 20 and the auxiliary plate 19 respectively;

[0046] When the second dust suppression plate 17 rotates, the protrusion 23 rotates simultaneously. The rotation of the protrusion 23 pushes the moving rod 20 to move upward, which causes the striking block 21 to strike the screening plate 12, thereby causing the screening plate 12 to vibrate. This effectively cleans the dust adhering to the screening plate 12, preventing dust from clogging the screening holes of the screening plate 12, thus ensuring normal screening of materials.

[0047] With the reset spring 22, when the second dust suppression plate 17 is reset, the protrusion 23 no longer blocks the moving rod 20. As a result, the reset spring 22 drives the moving rod 20 and the striking block 21 to reset. Therefore, the protrusion 23 can lift the moving rod 20 again when it rotates next time, thus ensuring that the striking block 21 can continuously strike the screening plate 12.

[0048] Working principle: When material falls into the hopper 8 through the screening plate 12, it gradually flows into the two second dust suppression plates 17 through the arc-shaped surface of the first dust suppression plate 14 and the through groove 24. When the weight of the accumulated material exceeds the load-bearing capacity of the second dust suppression plates 17, the two second dust suppression plates 17 rotate in opposite directions, causing the material to continue falling below the hopper 8. After the material has finished falling, the second dust suppression plates 17 return to their original position under the elasticity of the torsion spring 18, thus sealing the hopper 8 and preventing dust from flowing back up. This prevents dust from polluting external equipment and the environment. At the same time, because the first dust suppression plate 14 is arc-shaped and the two second dust suppression plates 17 are V-shaped, a dustproof cavity is formed between the first dust suppression plate 14 and the second dust suppression plate 17. Therefore, the dust generated during the falling process is blocked inside the cavity, effectively preventing dust from floating.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
