Description

Technical Field

[0001] This invention relates to the field of conveyor belt equipment technology, specifically a conveyor belt cleaning device. Background Technology

[0002] Belt conveyors are a common material conveying device, widely used in industries such as metallurgy, coal, chemical, mining, power, and grain. During operation, material often adheres to the conveyor belt. Therefore, belt conveyors are typically equipped with cleaning devices to remove material adhering to the conveyor belt's transport surface, reducing spillage and environmental pollution. These devices also minimize wear on conveyor rollers, drums, and other components, ensuring the normal operation of the belt conveyor.

[0003] Existing cleaning devices simply use brushes to clean materials and impurities on the conveyor belt surface, resulting in poor overall cleaning performance. When materials or impurities are in clumps and adhered to the conveyor belt surface, simple brush cleaning cannot effectively remove them. During continuous material conveying, the amount of clumps and impurities adhering to the conveyor belt surface continues to increase, affecting the normal use of the conveyor belt. Summary of the Invention

[0004] The purpose of this invention is to provide a conveyor belt cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

Multiple positioning rods are slidably installed on the surface of the fixed plate. The cleaning head is fixedly installed at the end of the positioning rod facing the conveyor belt. A baffle is fixedly installed on the surface of the positioning rod. A compression spring is fixedly installed on the bottom wall of the fixed plate. The compression spring is sleeved on the outside of the positioning rod and connected to the baffle.

[0009] As a further embodiment of the present invention: the telescopic part includes a control plate that is slidably installed in the cleaning box cavity along the vertical direction; a guide rod is fixedly installed in the cleaning box cavity below the control plate; a traction rope is fixedly installed at the end of the positioning rod away from the cleaning head; the end of the traction rope away from the positioning rod passes through the guide rod and is connected to the control plate; a top plate is slidably installed in the cleaning box cavity above the control plate; a guide cavity with two through ends is opened inside the top plate; two opposing inner sidewalls of the cleaning box are respectively rotatably installed with horizontal columns; a fixed plate is fixedly installed on the surface of the horizontal column; the two fixed plates are connected to a guide rod at a position off-center; the guide rod extends out from the guide cavity; synchronous gear plates are fixedly installed on the surface of the horizontal column and the bottom roller respectively; the two synchronous gear plates are connected to a synchronous belt; a lower magnetic plate is fixedly installed on the surface of the control plate; and an upper magnetic plate is fixedly installed on the bottom wall of the top plate.

[0010] As a further aspect of the present invention: a drying mechanism is provided on the outside of the cleaning box. The drying mechanism includes a wiping belt, a support component, and a dehydration component. The wiping belt is configured as a ring structure. The support component is located on the outside of the cleaning box and connected to the wiping belt. The support component is used to control the wiping belt to adhere to the surface of the conveyor belt. The dehydration component is connected to the support component and is used to squeeze and dehydrate the wiping belt.

[0011] As a further embodiment of the present invention: the support assembly includes two oppositely distributed side plates fixedly installed on the side wall of the cleaning box, and two oppositely distributed support rollers are rotatably installed on the two sets of side plates, and the wiping belt is sleeved on the surface of the two support rollers.

[0012] As a further aspect of the present invention: the dewatering assembly includes two squeezing rollers mounted together on two side plates, the two squeezing rollers being located on both sides of the conveyor belt, one end of the squeezing roller extending to the outside of the side plate and fixedly mounted with a control toothed disc, the two control toothed discs meshing with each other, and one end of one squeezing roller extending to the outside of the side plate and connected to a second motor.

This solves the problem that currently, when materials or impurities are in blocky form and pressed onto the surface of the conveyor belt, brush cleaning cannot effectively remove them, resulting in poor cleaning effect.

[0017] By setting up a support component and a dewatering component to work together, the wiping belt can be controlled to continuously wipe away water stains adhering to the surface of the conveyor belt, effectively improving the conveying effect of the conveyor belt on materials and preventing materials from adhering to the wet conveyor belt surface.

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 , Figure 2The diagram shows a structural representation of a conveyor belt cleaning device according to an embodiment of the present invention. It includes a conveyor frame 1, with positioning rollers 11 rotatably mounted at both ends of the conveyor frame 1. A conveyor belt 12 is positioned between the two sets of positioning rollers 11. One end of each set of positioning rollers 11 is connected to a first motor 13. A cleaning box 2 is positioned below the conveyor frame 1. A bottom roller 21 is rotatably mounted inside the cleaning box 2, with one end extending to the outside of the cleaning box 2 and connected to a drive motor. The conveyor belt 12 passes through the surface of the bottom roller 21. A cleaning mechanism 3 is provided inside the cleaning box 2, comprising a brushing component 31 and a tapping component 32. The brushing assembly 31 is located inside the cleaning box 2 and below the conveyor belt 12. The brushing assembly 31 is used to clean impurities attached to the surface of the conveyor belt 12. The tapping assembly 32 includes a cleaning head 321, a positioning part 322 and a telescopic part 323. The positioning part 322 is located inside the cleaning box 2 and is connected to the cleaning head 321. The positioning part 322 is used to support and position multiple cleaning heads 321 above the conveyor belt 12. The telescopic part 323 is located inside the cleaning box 2 and is connected to the positioning part 322. The telescopic part 323 is used to control the cleaning head 321 to intermittently tap the surface of the conveyor belt 12.

[0030] A suitable amount of water is injected into the cleaning tank 2. During use, the first motor 13 drives the positioning rollers 11 to rotate. The two sets of positioning rollers 11 cooperate with each other to drive the conveyor belt 12 to rotate on the surface of the conveyor frame 1. The conveyor belt 12 transports the material while rotating. The conveyor belt 12 moves the material to one end of the conveyor frame 1 for unloading. After unloading, the conveyor belt 12 continues to move towards the cleaning tank 2. When the conveyor belt 12 moves into the cleaning tank 2, it is immersed in the aqueous solution. As the conveyor belt 12 moves in the aqueous solution, the scrubbing component 31 can remove residual material and impurities adhering to the surface of the conveyor belt 12. The material is efficiently cleaned. While brushing, the telescopic part 323 controls the cleaning head 321 to intermittently and rapidly impact the conveyor belt 12 a certain distance. The cleaning head 321 can repeatedly tap the surface of the conveyor belt 12. During the tapping process, the cleaning head 321 can tap the blocky material and impurities pressed onto the surface of the conveyor belt 12, and can control the blocky material and impurities to separate from the conveyor belt 12, further improving the cleaning effect. After cleaning, the conveyor belt 12 continues to move. After the conveyor belt 12 moves to the upper surface of the conveyor frame 1, it can convey materials again.

[0031] like Figure 2 , Figure 3As shown, in a preferred embodiment of the present invention, the brushing assembly 31 includes a plurality of brush rods 311 rotatably mounted inside the cleaning chamber 2. The plurality of brush rods 311 are arranged side by side on the outside of the conveyor belt 12. The surface of the brush rods 311 is provided with bristles 312. The bottom roller 21 extends to the outside of the cleaning chamber 2 away from the drive motor and is fixedly mounted with a first drive toothed disc 313. The brush rods 311 extend to the outside of the cleaning chamber 2 and are fixedly mounted with a second drive toothed disc 314. The first drive toothed disc 313 and the plurality of second drive toothed discs 314 are connected together by a drive belt 315.

[0032] In use, the drive motor drives the bottom roller 21 to rotate around its own axis. The bottom roller 21 drives the first drive toothed disc 313 to rotate synchronously. The first drive toothed disc 313 cooperates with the drive belt 315 and multiple second drive toothed discs 314 to drive multiple brush rods 311 to rotate synchronously around their own axis. The brush rods 311 drive the brush bristles 312 to rotate synchronously. When rotating, the brush bristles 312 can efficiently clean the impurities attached to the surface of the conveyor belt 12.

[0033] like Figure 2 , Figure 3 , Figure 7 As shown, in a preferred embodiment of the present invention, the positioning part 322 includes a fixing plate 3221 fixedly installed in the inner cavity of the cleaning box 2 and located above the conveyor belt 12. A plurality of positioning rods 3222 are slidably installed on the surface of the fixing plate 3221. The cleaning head 321 is fixedly installed on the end of the positioning rod 3222 facing the conveyor belt 12. A baffle 3223 is fixedly installed on the surface of the positioning rod 3222. A compression spring 3224 is fixedly installed on the bottom wall of the fixing plate 3221. The compression spring 3224 is sleeved on the outside of the positioning rod 3222 and connected to the baffle 3223.

[0034] The fixing plate 3221 positions the positioning rod 3222, which in turn positions the cleaning head 321. When the conveyor belt 12 moves, the telescopic part 323 intermittently applies an upward pulling force to the positioning rod 3222, causing the telescopic part 323 to pull the positioning rod 3222 and the cleaning head 321 upward. At this time, the compression spring 3224 is in a compressed state. After the positioning rod 3222 and the cleaning head 321 have moved a certain distance, the telescopic part 323 releases the pulling force on the positioning rod 3222. At this time, the compression spring 3224 pushes the positioning rod 3222 and the cleaning head 321 to move rapidly toward the conveyor belt 12. The cleaning head 321 carries a large amount of kinetic energy and strikes the conveyor belt 12. When the cleaning head 321 strikes, it can control the separation of lumpy materials and impurities from the conveyor belt 12, further improving the cleaning effect.

[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, in a preferred embodiment of the present invention, the telescopic part 323 includes a control plate 3231 that is slidably mounted vertically in the inner cavity of the cleaning box 2. A guide rod 3232 located below the control plate 3231 is fixedly mounted in the inner cavity of the cleaning box 2. A traction rope 3233 is fixedly mounted at one end of the positioning rod 3222 away from the cleaning head 321. The other end of the traction rope 3233 away from the positioning rod 3222 passes through the guide rod 3232 and is connected to the control plate 3231. A top plate 3234 located above the control plate 3231 is slidably mounted vertically in the inner cavity of the cleaning box 2. The top plate 3234 has a through-hole opening at both ends. The guide cavity 3235 has two opposing inner sidewalls of the cleaning box 2 with horizontal columns 3236 rotatably mounted on them. The surface of the horizontal column 3236 is fixedly mounted with a fixed plate 3237. The two fixed plates 3237 are connected to a guide rod 3238 at a position off-center from the center. The guide rod 3238 passes through the guide cavity 3235. The surface of the horizontal column 3236 and the bottom roller 21 are fixedly mounted with synchronous gear discs 3239. The two synchronous gear discs 3239 are connected to a synchronous belt 32310. The surface of the control plate 3231 is fixedly mounted with a lower magnetic sheet 32311. The bottom wall of the top plate 3234 is fixedly mounted with an upper magnetic sheet 32312.

[0036] In use, the drive motor drives the bottom roller 21 to rotate around its own axis. The bottom roller 21 drives the synchronous gear plate 3239 to rotate synchronously. Multiple synchronous gear plates 3239 cooperate with the synchronous belt 32310 to drive the two horizontal columns 3236 on both sides of the cleaning box 2 to rotate synchronously around their own axis. The horizontal columns 3236 drive the fixed plate 3237 to rotate synchronously. The two fixed plates 3237 cooperate with each other to drive the guide rod 3238 to rotate in the vertical plane. The guide rod 3238 cooperates with the guide cavity 3235 to drive the top plate 3234 to move back and forth in the vertical direction. When the top plate 3234 moves to its lowest position, the upper magnetic piece 32312 on the bottom wall of the top plate 3234 is connected to the lower magnetic piece 32311 on the surface of the control plate 3231 by magnetic attraction, forming a whole. When the top plate 3234 moves upward, it drives the control plate 3231 to move upward synchronously. When the control plate 3231 moves upward, it cooperates with the traction rope 3233 to pull the positioning rod 3233 to move upward synchronously on the surface of the fixed plate 3221. When the positioning rod 3233 continues to move upward, the elastic thrust of the compression spring 3224 continues to increase. When the downward elastic thrust of the multiple compression springs 3224 is greater than the magnetic attraction between the upper magnetic piece 32312 and the lower magnetic piece 32311, the upper magnetic piece 32312 and the lower magnetic piece 32311 separate from each other. At this time, the top plate 3234 releases the restriction on the control plate 3231.

[0037] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, a drying mechanism 4 is provided on the outside of the cleaning box 2. The drying mechanism 4 includes a wiping belt 41, a support component 42, and a dehydration component 43. The wiping belt 41 is configured as a ring structure. The support component 42 is located on the outside of the cleaning box 2 and is connected to the wiping belt 41. The support component 42 is used to control the wiping belt 41 to adhere to the surface of the conveyor belt 12. The dehydration component 43 is connected to the support component 42 and is used to squeeze and dehydrate the wiping belt 41.

[0038] After the conveyor belt 12 is cleaned by the cleaning box 2, it continues to move. At this time, water stains are attached to the surface of the conveyor belt 12. As the conveyor belt 12 moves, the wiping belt 41 can automatically absorb the water stains on the surface of the conveyor belt 12. After wiping and absorbing the water, the surface of the conveyor belt 12 is dry, making it easy to convey materials again. The wiping belt 12 continues to absorb water, and the dewatering component 43 can clean the water accumulated on the surface of the wiping belt 12, making it easy for the wiping belt 12 to continuously clean the water stains on the surface of the conveyor belt 12.

[0039] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, in a preferred embodiment of the present invention, the support assembly 42 includes two oppositely distributed side plates 421 fixedly installed on the side wall of the cleaning box 2, and two oppositely distributed support rollers 422 are rotatably mounted on the two sets of side plates 421, and the wiping belt 41 is sleeved on the surface of the two support rollers 422.

[0040] The side plate 421 positions the support roller 422, and the two support rollers 422 position the wiping belt 41. The upper surface of the wiping belt 41 is attached to the surface of the conveyor belt 12. When the conveyor belt 12 moves, the wiping belt 41 can automatically absorb the water stains attached to the surface of the conveyor belt 12.

[0041] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, in a preferred embodiment of the present invention, the dewatering assembly 43 includes two squeezing rollers 431 that are rotatably mounted on two side plates 421. The two squeezing rollers 431 are respectively located on both sides of the conveyor belt 12. One end of the squeezing roller 431 extends to the outside of the side plate 421 and is fixedly mounted with a control toothed disc 432. The two control toothed discs 432 mesh with each other. One end of one squeezing roller 431 extends to the outside of the side plate 421 and is connected to a second motor 433.

[0042] During the wiping process, the second motor 433 drives a squeezing roller 431 to rotate. The squeezing roller 431 drives the control gear plate 432 to rotate synchronously. The two control gear plates 432 mesh with each other and drive the two squeezing rollers 431 to rotate in opposite directions. The two squeezing rollers 431 can perform efficient squeezing and dehydration treatment on the wiping belt 41.

[0043] like Figure 6 , Figure 8 As shown, in a preferred embodiment of the present invention, a base plate 5 located in the inner cavity of the wiping belt 41 is fixedly installed between the two sets of side plates 421. A plurality of support springs 51 are fixedly installed on the surface of the base plate 5, and the telescopic ends of the plurality of support springs 51 are connected to a pressure plate 52.

[0044] The base plate 5 positions the support spring 51, the support spring 51 positions the pressure plate 52, and the pressure plate 52 applies a pushing force to the wiping belt 41, further improving the adhesion effect of the wiping belt 41 to the conveyor belt 12.

[0045] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the bottom of the cleaning box 2 is provided with a funnel-shaped sedimentation chamber 6.

[0046] like Figure 2 , Figure 3 , Figure 4 As shown, in a preferred embodiment of the present invention, a limiting rod 7 is fixedly installed on the inner side wall of the cleaning box 2, and the control plate 3231 and the top plate 3234 are respectively slidably connected to the limiting rod 7 in the vertical direction. The limiting rod 7 can further improve the stability of the control plate 3231 and the top plate 3234 during movement.

[0047] The working principle of this invention is as follows: an appropriate amount of water is injected into the cleaning tank 2. During use, the first motor 13 drives the positioning roller 11 to rotate. The two sets of positioning rollers 11 cooperate with each other to drive the conveyor belt 12 to rotate on the surface of the conveyor frame 1. The conveyor belt 12 transports the material while rotating. The conveyor belt 12 moves the material to one end of the conveyor frame 1 for unloading. After unloading, the conveyor belt 12 continues to move towards the cleaning tank 2. When the conveyor belt 12 moves into the cleaning tank 2, it is immersed in the aqueous solution.

[0048] When the conveyor belt 12 travels in the aqueous solution, the drive motor drives the bottom roller 21 to rotate around its own axis. The bottom roller 21 drives the first drive toothed disc 313 to rotate synchronously. The first drive toothed disc 313 cooperates with the drive belt 315 and multiple second drive toothed discs 314 to drive multiple brush rods 311 to rotate synchronously around their own axis. The brush rods 311 drive the brush bristles 312 to rotate synchronously. When the brush bristles 312 rotate, they can efficiently clean the impurities attached to the surface of the conveyor belt 12.

[0049] The bottom roller 21 drives the synchronous gear plate 3239 to rotate synchronously. Multiple synchronous gear plates 3239 cooperate with the synchronous belt 32310 to drive the two horizontal columns 3236 on both sides of the cleaning box 2 to rotate synchronously around their own axis. The horizontal columns 3236 drive the fixed plate 3237 to rotate synchronously. The two fixed plates 3237 cooperate with each other to drive the guide rod 3238 to rotate in the vertical plane. The guide rod 3238 cooperates with the guide cavity 3235 to drive the top plate 3234 to move back and forth in the vertical direction. When the top plate 3234 moves to its lowest position, the upper magnetic plate 32312 on the bottom wall of the top plate 3234 is connected to the lower magnetic plate 32311 on the surface of the control plate 3231 by magnetic attraction, forming a whole. When the top plate 3234 moves upward, it drives the control plate 3231 to move upward synchronously. When the control plate 3231 moves upward, it cooperates with the traction rope 3233 to pull the positioning rod 3233 to move upward synchronously on the surface of the fixed plate 3221. When the positioning rod 3233 continues to move upward, the elastic thrust of the compression spring 3224 continues to increase. When multiple compression springs 3224 move downward... When the elastic thrust is greater than the magnetic attraction between the upper magnetic sheet 32312 and the lower magnetic sheet 32311, the upper magnetic sheet 32312 and the lower magnetic sheet 32311 separate from each other. At this time, the top plate 3234 releases the restriction on the control plate 3231. At this time, the compression spring 3224 pushes the positioning rod 3222 and the cleaning head 321 to move quickly towards the conveyor belt 12. The cleaning head 321 carries a large kinetic energy to strike the conveyor belt 12. When the cleaning head 321 strikes, it can control the blocky materials and impurities to separate from the conveyor belt 12, further improving the cleaning effect.

[0050] The preferred embodiments of the present invention have been described in detail above. 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.
