Description

Technical Field

[0001] The utility model belongs to the technical field of transportation, and in particular relates to a slag conveyor. Background Art

[0002] In the construction of underground transportation systems, shield machines are often used to dig tunnels, and the slag produced by tunnel digging is usually transported by slag conveyors. However, tunnel digging is usually carried out underground or in the surface layer that is rarely exposed to sunlight. The slag in the ground or on the surface often combines with the moisture in the ground or on the surface to form clay. Therefore, during the long-term use of the slag conveyor, clay may adhere to the conveyor belt of the slag conveyor, and this clay is difficult to clean.

[0003] The existing patent number is CN220578256U, which is a wear-resistant rubber conveyor belt, including a conveyor frame, a rubber conveyor belt, an electric telescopic rod, a bottom plate, a vertical rod, a connecting rod, a main rod, bristles, an external connecting pipe, a connecting head and a water spray head. The telescopic rod drives the bottom plate to move, the bottom plate drives the vertical rod to move, the vertical rod drives the connecting rod to move, and the connecting rod drives the bristles to contact the rubber conveyor belt to clean the rubber conveyor belt. However, the device does not have a device for cleaning the bristles. The bristles are easily attached with clay in the process of continuously cleaning the rubber conveyor belt, which affects the subsequent cleaning effect. Utility Model Content

[0004] The utility model discloses a slag conveyor, which is intended to solve the technical problem in the prior art that the clay cleaning parts cannot be self-cleaned and affect the subsequent cleaning effect.

[0005] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present utility model are as follows:

[0006] A slag conveyor comprises a conveying portion provided with a conveyor belt, characterized in that: the conveying portion is provided with a cleaning portion capable of cleaning the conveyor belt, the cleaning portion comprises a first scraper connected to the conveying portion, the first scraper contacts with the conveyor belt to scrape the conveyor belt, a cleaning device is provided at the scraping position of the first scraper, the cleaning device comprises a second scraper in contact with the first scraper, the second scraper is connected to a driving device, and the driving device drives the second scraper to scrape at the scraping position of the first scraper.

[0007] After adopting this technical solution, this technical solution changes the existing method of using bristles to clean the rubber conveyor belt, and uses a scraper to clean the conveyor belt. Compared with bristles, it can not only enhance the cleaning effect, but also facilitate the self-cleaning of the clay cleaning part. In this technical solution, the conveyor belt contacts the first scraper during the continuous transportation process, and the first scraper scrapes and cleans the clay attached to the conveyor belt.

[0008] When clay is attached to the scraper, the driving device can be started to drive the second scraper to move to the scraping area of ​​the first scraper to clean the clay attached to the scraping area, thereby realizing the self-cleaning of the clay cleaning component. The first scraper cleans the conveyor belt, and the second scraper cleans the first scraper, so that when the first scraper cleans the debris on the conveyor belt, the scraping area of ​​the first scraper can remain flat and scrape the debris on the conveyor belt. Because there is no clay accumulation on the scraping area of ​​the first scraper, it is easier to scrape the clay off the conveyor belt when the debris on the conveyor belt is continuously scraped. Therefore, the provision of the second scraper etc. improves the cleaning effect of the clay attached to the conveyor belt of the slag conveyor, which is beneficial to reducing the clay attached to the conveyor belt, thereby reducing the contact between the new slag and the clay attached to the conveyor belt when the conveyor belt transports a new batch of slag, and the friction on the conveyor belt caused by the two; at the same time, it reduces the clay attached to the first scraper, and thereby reduces the friction between the first scraper and the conveyor belt caused by the contact between the clay attached to the first scraper and the clay attached to the conveyor belt, thereby reducing the friction and wear on the entire equipment and extending the service life of the equipment.

[0009] The improved clay cleaning effect on the slag conveyor can also avoid the problem of slag accumulation on the conveyor belt affecting the running speed of the conveyor belt due to poor slag cleaning effect, thereby improving the transportation efficiency of the slag.

[0010] Among them, the driving device includes a first telescopic device and a second telescopic device arranged on both sides of the second scraper, the first telescopic device includes a bellows, the bellows is connected to a connecting pipe, the connecting pipe is connected to a water source or an air source, a switch is provided on the side where the bellows is connected to the second scraper, the second scraper is a hollow structure, and an outlet is provided on the second scraper, and the switch connects the bellows and the hollow structure.

[0011] After adopting this technical solution, a water source or an air source, for example, clean water, can be injected into the bellows through the connecting pipe. During this injection process, the clean water gradually fills the bellows and causes the length of the bellows to change. At this time, the extension direction of the bellows extends toward the direction close to the second telescopic device. The bellows pushes the second scraper to generate a thrust toward the second telescopic device. During this process, the second telescopic device has an elastic force to move toward the first telescopic device, but the elastic force is smaller than the thrust. The second scraper continues to move toward the direction close to the second telescopic device to clean the first scraper.

[0012] When the second scraper squeezes the second telescopic device to the limit, that is, when the second scraper moves to the edge close to the other end of the first scraper, the switch between the bellows and the second scraper is turned on, and the cleaning water gradually fills the second scraper and overflows from the opening on the second scraper. At this time, because the cleaning water overflows from the opening on the second scraper, the cleaning water no longer generates thrust on the second scraper through the bellows, and the elastic force on the second telescopic device is greater than the thrust. Under the action of the elastic force, the second telescopic device pushes the second scraper back to its original position, and cooperates with the cleaning water overflowing from the opening to clean the residual clay on the surface of the first scraper and the second scraper again. When the first telescopic device moves to the initial position, that is, the position where the cleaning water is not injected into the bellows, the switch is turned off, and then the above process is repeated to clean the clay attached to the scraping place of the first scraper and the clay remaining on the first scraper and the second scraper. This device combines water cleaning and scraping cleaning together to improve the cleaning effect of the first scraper.

[0013] Wherein, the second telescopic device is a telescopic spring.

[0014] After adopting this technical solution, the expansion and contraction of the expansion and contraction of the expansion and contraction of the bellows, the introduction of the water source or the air source, and the opening and closing of the switch make the second scraper reciprocate at the scraping place of the first scraper to clean the scraping place, thereby improving the cleaning effect of the first scraper. At the same time, the second expansion and contraction device adopts the expansion and contraction of the bellows, which can reduce the material and structural costs of the device.

[0015] Among them, a sliding groove is arranged on the scraping part of the first scraper, a sliding block cooperating with the sliding groove is arranged on the second scraper, the first telescopic device and the second telescopic device are both connected to the sliding block, and the first telescopic device and the second telescopic device are both arranged in the sliding groove.

[0016] After adopting this technical solution, the stability of the second scraper sliding at the scraping place of the first scraper can be improved through the connection and sliding of the slider and the slide groove, and the setting of the slide groove and the slider limits the position of the second scraper, so that the second scraper can only move back and forth at the scraping place of the first scraper and will not shift to other positions. Therefore, the setting of the slider and the slide groove not only increases the stability of the device when in use, but also limits the position of the second scraper moving at the scraping place of the first scraper, so that the device has a better cleaning effect on the first scraper.

[0017] Wherein, the slide groove and the sliding block are both T-shaped structures.

[0018] After adopting this technical solution, the T-shaped slide groove and the slider are more stable when connected to each other, making it difficult for the slider to fall out of the slide groove, which can further improve the stability of the connection between the second scraper and the scraping part.

[0019] Wherein, the scraping part on the first scraper is an inclined surface structure, and the inclined surface structure is arranged relative to the moving direction of the conveyor belt.

[0020] After adopting this technical solution, the scraping part of the first scraper is set as a sloped structure. The setting of the sloped structure first facilitates the processing of the first scraper. At the same time, the sloped structure is set relative to the movement direction of the conveyor belt, so that the sloped structure can more easily scrape off the clay on the conveyor belt, thereby improving the cleaning efficiency.

[0021] Wherein, the conveying part comprises two brackets with the same structure and symmetrically arranged positions, the two brackets are connected by a plurality of conveying rollers, the plurality of conveying rollers form a conveying plane, and the conveying belt is sleeved on the conveying plane.

[0022] After adopting this technical solution, the setting of several conveying rollers and brackets can support the conveyor belt and improve the stability of the conveyor belt when conveying debris.

[0023] Wherein, the first scraper is clamped on the bracket through a C-shaped clamping plate.

[0024] After adopting this technical solution, the first scraper and the like can be directly connected to the bracket and the like on the conveying part through the C-shaped clamping plate without affecting the position of the conveyor belt conveying the debris, so that the first scraper and the like are closer to the conveyor belt, and when the first scraper and the like are damaged, it is convenient to replace the first scraper and the like, thereby increasing the practicality of the device when in use.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0026] (1) The first scraper, the second scraper, etc. are used to clean the conveyor belt and the first scraper, thereby improving the cleaning effect of the clay on the slag conveyor, which is beneficial to reducing the friction and wear on the equipment and extending the service life of the equipment. At the same time, it can prevent the accumulation of debris and dust from affecting the running speed of the conveyor belt, thereby improving the transportation efficiency of slag.

[0027] (2) By using a bellows, a connecting pipe, an outlet, a switch, etc., when the second scraper scrapes and cleans the first scraper, the first scraper is simultaneously rinsed with water, thereby improving the cleaning effect of the first scraper.

[0028] (3) The use of a slider and a slide groove can improve the stability of the connection between the second scraper and the scraping part, and further improve the stability of the device when in use.

[0029] (4) A C-shaped card plate is used to make the first scraper and the conveying part detachably connected, so that the entire cleaning part can be replaced when the cleaning part is damaged, thereby improving the practicality of the device during use. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0040] Combine the following Figure 1-Figure 5 The utility model is described in detail.

[0041] Example 1

[0042] A slag conveyor, such as Figure 1-Figure 5 As shown, it includes a conveying part 1 provided with a conveyor belt 103, the conveying part 1 is provided with a cleaning part which can clean the conveyor belt 103, the cleaning part includes a first scraper 2 connected to the conveying part 1, the first scraper 2 contacts with the conveyor belt 103 to scrape the conveyor belt 103, a cleaning device 3 is provided at the scraping position of the first scraper 2, the cleaning device 3 includes a second scraper 302 in contact with the first scraper 2, the second scraper 302 is connected with a driving device, and the driving device drives the second scraper 302 to scrape at the scraping position of the first scraper 2.

[0043] In this embodiment, the first scraper 2 is made of stainless steel. Stainless steel is corrosion-resistant, rust-resistant, wear-resistant, high-strength, neat and beautiful in appearance, and has a long service life. Using the first scraper 2 made of stainless steel can achieve the effect of reducing costs.

[0044] In this embodiment, the side of the first scraper 2 that is in contact with the conveyor belt 103 is smooth, and the end portion that is in contact with the conveyor belt 103 at the scraping portion is a thin sheet with a thickness ranging from 0.5-5 mm. In this embodiment, the thickness is 1 mm, which is relatively thin. Therefore, the first scraper 2 can quickly remove the clay attached to the surface of the conveyor belt 103 without causing damage to the conveyor belt 103. At the same time, it has a certain thickness so that the scraping portion of the first scraper 2 is not easy to bend, thereby extending the service life of the first scraper 2.

[0045] In this embodiment, the second scraper 302 is made of stainless steel, and includes two symmetrically arranged working surfaces, which are inclined relative to the scraping part of the first scraper 2. Figure 2 and Figure 3As shown, when the second scraper 302 is moved horizontally at the scraping position of the first scraper 2, it is easier to clean the clay attached to the first scraper 2, thereby improving the cleaning effect.

[0046] In this embodiment, the scraping portion on the first scraper 2 is an inclined surface structure, and the inclined surface structure is arranged relative to the moving direction of the conveyor belt 103 .

[0047] The scraping part of the first scraper 2 is set as an inclined structure. The setting of the inclined structure first facilitates the processing of the first scraper 2. At the same time, the inclined structure is set relative to the movement direction of the conveyor belt 103, so that the inclined structure can more easily scrape off the clay on the conveyor belt 103, thereby improving the cleaning efficiency.

[0048] In this embodiment, the cleaning device 3 is arranged on the side of the conveying part 1 close to the ground, and the conveyor belt 103 moves clockwise. When the conveyor belt 103 transports the debris to the edge of the conveyor belt 103, the conveyor belt 103 turns to the opposite side for transporting the debris, that is, the rotating side that does not need to transport the debris. The cleaning part cleans the conveyor belt 103 on the rotating side, which can reduce the cleaning difficulty and the workload of the cleaning part, thereby increasing the service life of the cleaning part.

[0049] The present technical solution changes the existing method of using bristles to clean the rubber conveyor belt 103, and uses a scraper to clean the conveyor belt 103. Compared with bristles, it can not only enhance the cleaning effect, but also facilitate the self-cleaning of the clay cleaning part. In the present technical solution, the conveyor belt 103 contacts the first scraper 2 during the continuous transportation process, and the first scraper 2 scrapes and cleans the clay attached to the conveyor belt 103.

[0050] When clay is attached to the scraper, the driving device can be started to drive the second scraper 302 to move at the scraping place of the first scraper 2 to clean the clay attached to the scraping place, thereby realizing self-cleaning of the clay cleaning component.

[0051] The conveyor belt 103 is cleaned by the first scraper 2, and the second scraper 302 cleans the first scraper 2, so that when the first scraper 2 cleans the dirt on the conveyor belt 103, the scraping part of the first scraper 2 can remain flat, and the dirt on the conveyor belt 103 is scraped. Because there is no clay accumulation on the scraping part of the first scraper 2, it is easier to scrape the clay off the conveyor belt 103 when the dirt on the conveyor belt 103 is continuously scraped. Therefore, the provision of the second scraper 302 and the like improves the cleaning effect of the clay attached to the conveyor belt 103 of the slag conveyor, and is beneficial to reducing the clay attached to the conveyor belt 103, thereby reducing the contact between the new slag and the clay attached to the conveyor belt 103 when the conveyor belt 103 transports a new batch of slag, and the friction between the conveyor belt 103 and the conveyor belt 103 caused by the two; at the same time, the clay attached to the first scraper 2 is reduced, thereby reducing the friction between the first scraper 2 and the conveyor belt 103 caused by the contact between the clay attached to the first scraper 2 and the clay attached to the conveyor belt 103, thereby reducing the friction and wear on the entire equipment and extending the service life of the equipment.

[0052] After the clay cleaning effect on the slag conveyor is improved, it can also avoid the problem of slag accumulation on the conveyor belt 103 affecting the running speed of the conveyor belt 103 due to poor slag cleaning effect, thereby improving the transportation efficiency of the slag.

[0053] In this embodiment, the driving device includes a first telescopic device and a second telescopic device arranged on both sides of the second scraper 302, the first telescopic device includes a bellows 301, the bellows 301 is connected to a connecting pipe 201, the connecting pipe 201 is connected to a water source or an air source, a switch 303 is provided on the side where the bellows 301 is connected to the second scraper 302, the second scraper 302 is a hollow structure, and an outlet 304 is provided on the second scraper 302, and the switch 303 connects the bellows 301 and the hollow structure.

[0054] In this embodiment, water is used to transport air into the connecting pipe 201 . In other embodiments, hot air or cold air may be used as an air source to transport air into the connecting pipe 201 .

[0055] In this embodiment, a through groove for accommodating the connecting pipe 201 is provided on the first scraper 2. After passing through the through groove, the connecting pipe 201 is sealed and connected with the bellows 301, and the connecting pipe 201 is connected to a water pump placed in a water tank. Clean water can be input into the connecting pipe 201 through the water pump, and then clean water is input into the bellows 301.

[0056] In this embodiment, a water source, for example, clean water, can be injected into the bellows 301 through the connecting pipe 201. During the injection process, the clean water gradually fills the bellows 301 and causes the length of the bellows 301 to change. At this time, the extension direction of the bellows 301 extends toward the direction close to the second telescopic device. The bellows 301 pushes the second scraper 302 to generate a thrust toward the second telescopic device. The second telescopic device has an elastic force to move toward the first telescopic device during this process, but the elastic force is smaller than the thrust. The second scraper 302 continues to move toward the direction close to the second telescopic device to clean the first scraper 2.

[0057] When the second scraper 302 squeezes the second telescopic device to the limit, that is, moves to the other edge of the first scraper 2, the switch 303 between the bellows 301 and the second scraper 302 is opened, and the cleaning water gradually fills the second scraper 302 and overflows from the opening on the second scraper 302. At this time, because the cleaning water overflows from the opening on the second scraper 302, the cleaning water no longer generates thrust on the second scraper 302 through the bellows 301, and the elastic force on the second telescopic device is greater than the thrust. Under the action of the elastic force, the second telescopic device pushes the second scraper 302 back to its original position, and cooperates with the cleaning water overflowing from the opening to clean the residual clay on the surface of the first scraper 2 and the second scraper 302 again.

[0058] When the first telescopic device moves to the initial position, i.e., the position where no cleaning water is injected into the bellows 301, the switch 303 is closed, and then the above process is repeated to clean the clay attached to the scraping place of the first scraper 2 and the clay remaining on the first scraper 2 and the second scraper 302. The device combines water cleaning and scraping cleaning together, thereby improving the cleaning effect of the first scraper 2.

[0059] In this embodiment, the outlet 304 is arranged in the direction of the second scraper 302 close to the conveyor belt 103. When water such as cleaning water flows out from the outlet 304, it is equivalent to flowing out directly from the top of the second scraper 302, contacting the top of the scraping part of the first scraper 2, and flowing from the top of the scraping part of the first scraper 2 to the bottom of the scraping part of the first scraper 2, cleaning the impurities attached to the scraping part of the first scraper 2, and cooperating with the second scraper 302 to simultaneously clean the impurities attached to the second scraper 302. Therefore, the outlet 304 is arranged at this position, which has the effect of improving the self-cleaning effect of the device.

[0060] In this embodiment, the second telescopic device is a telescopic spring 306 .

[0061] In this embodiment, the telescopic spring 306 is made of stainless steel.

[0062] Through the expansion and contraction of the telescopic spring 306, the expansion and contraction of the bellows 301, the introduction of water, and the opening and closing of the switch 303, the second scraper 302 reciprocates at the scraping area of ​​the first scraper 2 to clean the scraping area, thereby improving the cleaning effect of the first scraper 2. At the same time, the second telescopic device uses the telescopic spring 306, which can reduce the material and structural costs of the device.

[0063] In this embodiment, a slide groove 202 is provided on the scraping portion of the first scraper 2, and a slider 305 cooperating with the slide groove 202 is provided on the second scraper 302, the first telescopic device and the second telescopic device are both connected to the slider 305, and the first telescopic device and the second telescopic device are both arranged in the slide groove 202.

[0064] In this embodiment, the slider 305 and the second scraper 302 are integrally formed.

[0065] In this embodiment, one end of the bellows 301 is sealed and adhered to the slider 305. After the switch 303 is turned on, the inner cavity of the bellows 301 is connected to the slider 305. One end of the telescopic spring 306 is fixedly connected to the slider 305 by welding. The other ends of the bellows 301 and the telescopic spring 306 are adhered and welded to the slide groove 202 respectively.

[0066] In this embodiment, a layer of elastic fabric is provided on the outer side of the telescopic spring 306 , and the elastic fabric can change along with the telescopic spring 306 to shield and protect the slide groove 202 and prevent impurities from entering the slide groove 202 .

[0067] In this embodiment, the switch 303 is a valve, which is electrically controlled by the control unit. A laser rangefinder is provided at one end of the first telescopic device connected to the slide 202, and a receiver is provided at the side of the second scraper 302 opposite to the laser rangefinder. The laser rangefinder can measure the distance between the second scraper 302 and the laser rangefinder. Initially, the second scraper 302 is located close to the laser rangefinder. Then, when the bellows 301 is gradually filled with water, the second scraper 302 begins to move toward a position away from the laser rangefinder. When the movement distance of the second scraper 302 reaches the first set value, that is, when the telescopic spring 306 is compressed to the end of the first scraper 2, the laser rangefinder transmits the information to the control unit, and the control unit controls the valve to open, and the cleaning water enters the slider 305 from the valve and gradually fills the hollow structure of the second scraper 302, and then overflows from the outlet 304 on the second scraper 302 to clean the scraped area on the first scraper 2. At this time, it is equivalent to that the cleaning water is depressurized from the outlet 304 . Therefore, although the cleaning water still overflows from the outlet 304 , in fact, the cleaning water does not generate any thrust on the second scraper 302 .

[0068] Then, the second scraper 302 gradually approaches the laser rangefinder under the action of the resilience of the telescopic spring. When the distance is less than the second set value, that is, when the second scraper 302 approaches the laser rangefinder, the laser rangefinder transmits the information to the control unit, and the control unit controls the valve to close, and the bellows 301 is gradually filled with clean water again, and then the above process is repeated to clean the first scraper 2. In other embodiments, in order to extend the life of the laser rangefinder and protect the laser rangefinder, a protective cover can be set on the surface of the laser rangefinder, and the end of the protective cover can be made of a hydrophobic material such as a waterproof coating fabric, which can not only protect the laser rangefinder, but also prevent sewage from sticking to the laser rangefinder, thereby improving the working stability of the laser rangefinder.

[0069] In other embodiments, the valve can also be opened manually. When a certain amount of clay is attached to the first scraper 2 (for example, in this embodiment, after a day of use, the staff can start the cleaning device 3 to clean the first scraper 2), the staff can directly start the water pump first, and use the water pump to transfer water to the bellows 301. Because the flow rate of the cleaning water is constant, after a certain period of time (for example, after 30 seconds), the second scraper 302 moves to the other end of the first scraper 2. At this time, the staff turns on the switch 303 again, so that the cleaning water gradually fills the second scraper 302 and overflows from the outlet 304 on the second scraper 302, and the cleaning water is depressurized. Then, after the second scraper 302 returns to the initial position under the rebound force of the telescopic spring 306, the staff turns off the water pump and the switch 303.

[0070] In this embodiment, the outer diameter of the bellows 301 matches the size of the slide groove 202. When the bellows 301 is extended or retracted, the slide groove 202 can be shielded to prevent impurities from entering the slide groove 202, thereby ensuring the normal use of the slide groove 202 and the slider 305.

[0071] The connection and sliding of the slider 305 and the slide groove 202 can improve the stability of the second scraper 302 sliding at the scraping place of the first scraper 2, and the setting of the slide groove 202 and the slider 305 limits the position of the second scraper 302, so that the second scraper 302 can only move back and forth at the scraping place of the first scraper 2 and will not shift to other positions. Therefore, the setting of the slider 305 and the slide groove 202 not only increases the stability of the device when in use, but also limits the position of the second scraper 302 moving at the scraping place of the first scraper 2, so that the cleaning effect of the device on the first scraper 2 is better.

[0072] In this embodiment, the slide groove 202 and the slider 305 are both T-shaped structures.

[0073] In this embodiment, the slide groove 202 and the slider 305 are vertically arranged. The T-shaped slide groove 202 and the slider 305 that are vertically arranged can effectively limit the position of the slider 305 and prevent the slider 305 from falling off from the slide groove 202.

[0074] The T-shaped slide groove 202 and the slider 305 are more stable when connected to each other, so that the slider 305 is not easy to escape from the slide groove 202, which can further improve the stability of the connection between the second scraper 302 and the scraping part.

[0075] In this embodiment, the conveying part 1 includes two brackets 102 with the same structure and symmetrical positions. The two brackets 102 are connected by a plurality of conveying rollers 101. The plurality of conveying rollers 101 form a conveying plane, and the conveying belt 103 is sleeved on the conveying plane.

[0076] In this embodiment, the bracket 102 is made of stainless steel.

[0077] In this embodiment, the structure of the conveying part 1 is an existing structure, including a conveying roller 101, a bracket 102, a conveying belt 103, a tensioning wheel, a motor, etc. The working principle of the conveying part 1 is also existing technology and will not be described in detail here.

[0078] In this embodiment, the first scraper 2 is clamped on the bracket 102 through a C-shaped clamping plate 4.

[0079] In this embodiment, four C-shaped clamps 4 are symmetrically arranged, and the C-shaped clamps 4 are threadedly connected to the first scraper 2. The C-shaped clamps 4 and the first scraper 2 are provided with connecting threaded holes, and the connecting threaded holes are detachably connected with connecting bolts.

[0080] In this embodiment, Figure 2 As shown, the C-shaped clamping plate 4 is clamped with the bracket 102. After the C-shaped clamping plate 4 is clamped on the bracket 102, the C-shaped clamping plate 4 and the bracket 102 are connected by bolts.

[0081] The C-shaped clamping plate 4 can directly clamp the first scraper 2 and the like to the bracket 102 and the like on the conveying part 1 without affecting the position of the conveyor belt 103 for conveying debris, so that the first scraper 2 is closer to the conveyor belt 103, and when the first scraper 2 and the like are damaged, it is convenient to replace the first scraper 2 and the like, thereby increasing the practicality of the device when in use.

[0082] The specific use method of the utility model is as follows:

[0083] Reference Figure 1-Figure 5When the device is used, the cleaning part is first sleeved on the conveying part 1 through the C-shaped card plate 4, so that the first scraper 2 contacts the conveyor belt 103 at the rotating position, and the inclined surface structure of the first scraper 2 is aligned with the moving direction of the conveyor belt 103. When the C-shaped card plate 4 is clamped with the bracket 102, the bolts are tightened to tighten the C-shaped card plate 4 and the bracket 102.

[0084] After the conveyor belt 103 at the transportation area has transported the slag, the conveyor belt 103 will directly enter the rotating area and contact the cleaning part under the drive of the driving structure of the slag conveying device. When clay is attached to the surface of the conveyor belt 103 entering the rotating area, the inclined structure of the first scraper 2 will directly scrape the clay off. Most of the scraped clay will fall directly to the ground, and a small part will adhere to the inclined structure of the first scraper 2.

[0085] When clay is attached to the inclined surface structure of the first scraper 2, the water pump can be started to transport clean water to the connecting pipe 201, and the clean water enters the bellows 301 from the connecting pipe 201. As the clean water continues to enter the bellows 301, the bellows 301 continues to extend in the slide groove 202, squeezing the slider 305, so that the second scraper 302 moves in the direction of the telescopic spring 306, scraping and cleaning the clay attached to the inclined surface structure of the first scraper 2, and at the same time, the slider 305 will also generate a squeezing force on the telescopic spring 306. , so that the telescopic spring 306 has the elastic force to move toward the bellows 301. When the bellows 301 squeezes the second scraper 302 to reach the edge of the first scraper 2 close to the chute 202, the laser rangefinder measures that the distance between the second scraper 302 and the laser rangefinder reaches the first set value. The control unit controls to open the switch 303, and the cleaning water enters the second scraper 302 from the switch 303, and then flows out from the outlet 304 of the second scraper 302 to wash the residual clay on the first scraper 2 and the clay attached to the second scraper 302.

[0086] At this time, the elastic force of the telescopic spring 306 is greater than the pressure of the water pressure in the bellows 301, and the telescopic spring 306 pushes the second scraper 302 to move in the direction close to the bellows 301, and cleans the entire cleaning part together with the outflowing cleaning water. The cleaning water in the bellows 301 flows out while the water pump replenishes the bellows 301. When the bellows 301 shrinks to one side of the chute 202, the laser rangefinder measures that the distance between the second scraper 302 and the laser rangefinder reaches the second set value. The laser rangefinder transmits this information to the control unit, and the control unit controls the valve to close, and the cleaning water refills the bellows 301, and repeats the above process to clean the first scraper 2.

[0087] This device can achieve self-cleaning of the cleaning part, improve the cleaning effect of clay on the slag conveyor, help reduce friction and wear on the equipment, extend the service life of the equipment, and at the same time avoid the accumulation of debris and dust affecting the running speed of the conveyor belt 103, thereby improving the transportation efficiency of slag.
