Description

Technical Field

[0001] The invention relates to the technical field of cleaning mining conveyor belts, and more particularly to an automatic cleaning and maintenance device for mining conveyor belts. Background Art

[0002] In the process of mine transportation, belt conveyors are key equipment for efficient material transportation. Their operating efficiency and maintenance status directly affect the continuity and economy of mine production. However, belts will inevitably be contaminated with materials, dust and other pollutants during long-term operation. If they are not cleaned in time, it will not only cause belt wear to increase and shorten service life, but also cause belt deviation, tearing and other problems. In addition, traditional cleaning devices mostly use mechanical scrapers or brush rollers. Although these methods can remove some pollutants, they cause great damage to the belt surface, incomplete cleaning effect, and easy generation of secondary dust.

[0003] In recent years, although some new cleaning technologies have emerged, such as high-pressure water jets and airflow cleaning, these methods often require complex equipment and high energy consumption, and it is difficult to balance cleaning effects and belt protection in practical applications. For example, although some cleaning devices can achieve a certain degree of cleaning effect, the design of their water spray devices and cleaning components fails to fully consider the protection of the belt, which can easily cause damage to the belt surface. In addition, some cleaning devices have complex structures and are inconvenient to maintain, making it difficult to adapt to the complex working environment of mines.

[0004] Therefore, developing a belt cleaning and maintenance device that can achieve low damage and high efficiency cleaning has become a technical problem that needs to be solved urgently in the field of mining transportation. This device needs to effectively remove pollutants on the belt surface while minimizing damage to the belt, extending the belt service life, reducing maintenance costs, and improving the working environment. Summary of the invention

[0005] In view of this, the present invention provides an automatic cleaning and maintenance device for a mine conveyor belt, aiming to solve the above technical problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] An automatic cleaning and maintenance device for a mine conveyor belt, comprising a mine belt conveyor support, and a conveyor belt mounted on the mine belt conveyor support; and further comprising: a dust removal part, a water washing part and a drying part sequentially arranged in the conveying direction of the lower belt body of the conveyor belt;

[0008] The dust removal part includes a blowing and vibrating mechanism arranged below the lower belt body, and a hammering and vibrating mechanism arranged above the lower belt body and corresponding to and cooperating with the blowing and vibrating mechanism. The blowing and vibrating mechanism blows the dust on the lower surface of the lower belt body, and uses the blowing force of the blowing and vibrating mechanism to make the lower belt body fluctuate, and cooperates with the hammering and vibrating mechanism to strike and shake off the dust;

[0009] The water washing part includes a flushing mechanism and a sweeping and washing mechanism arranged in sequence in the conveying direction of the lower belt body; the flushing mechanism flushes along the direction of the lower surface of the lower belt body by spraying water; the sweeping and washing mechanism sweeps the lower surface of the lower belt body by combining water flushing and a brush structure;

[0010] The drying part dries the water stains on the lower surface of the lower belt body by blowing air.

[0011] Through the above technical solutions, the present invention realizes the comprehensive cleaning and maintenance of the mine transportation belt through the sequential arrangement of the dust removal part, the water washing part and the drying part, avoids the damage to the belt caused by the long-term accumulation of pollutants, and prolongs the service life of the belt; the dust removal part adopts the cooperation mode of the blowing and vibrating mechanism and the hammering and vibrating mechanism, uses the blowing force to make the lower belt body fluctuate, and cooperates with the hammering and vibrating mechanism to strike and shake off the dust, and can efficiently remove the dust on the belt surface, improving the cleaning effect. Compared with the traditional mechanical scraper or brush roller cleaning method, this combination of blowing and hammering causes less damage to the belt surface and avoids excessive wear of the belt caused by cleaning.

[0012] Preferably, in the above-mentioned automatic cleaning and maintenance device for a mine transportation belt, the dust removal part further includes a dust removal protection housing, the dust removal protection housing surrounds the outside of the lower belt body, and the front and rear side walls respectively have a dust removal housing inlet and a dust removal housing outlet for the lower belt body to pass through, and the blowing and vibrating mechanism and the hammering and vibrating mechanism are both installed inside the dust removal protection housing; the water washing part further includes a water washing protection housing, the water washing protection housing surrounds the outside of the lower belt body, and the front and rear side walls respectively have a water washing housing inlet and a water washing housing outlet for the lower belt body to pass through, and the flushing mechanism and the sweeping and washing mechanism are both installed inside the water washing protection housing.

[0013] The dust removal part and the water washing part are respectively provided with a dust removal protection housing and a water washing protection housing, which can effectively enclose and collect the dust and sewage generated during the cleaning process, prevent the dust and sewage from overflowing, and avoid secondary pollution to the surrounding environment. The design of the protection housing makes the structure of the entire cleaning and maintenance device more compact, and at the same time relatively isolates the cleaning components and the belt operation area, improving the safety of equipment operation and reducing the safety accidents that may be caused by dust flying or sewage splashing.

[0014] Preferably, in the above-mentioned automatic cleaning and maintenance device for a mine transportation belt, the dust removal part further includes dust removal follower rollers and dust removal clamping rollers; the number of the dust removal follower rollers is two, and both of the two dust removal follower rollers are arranged above the lower belt body and on the front and rear sides of the hammer vibration mechanism; the number of the dust removal clamping rollers is two, and both of the two dust removal clamping rollers are arranged below the lower belt body and correspond to the two dust removal follower rollers respectively. When the blowing and vibration mechanism is started, the dust removal clamping rollers can cooperate with the corresponding dust removal follower rollers under the control of the first telescopic mechanism to clamp the lower belt body.

[0015] The dust removal part is increased with dust removal follower rollers and dust removal clamping rollers. Through the control of the first telescopic mechanism, the dust removal clamping rollers can cooperate with the dust removal follower rollers to clamp the lower belt body. During the cleaning process, this clamping structure can stabilize the belt, prevent the belt from running off or shaking during vibration cleaning, and ensure the stability of the cleaning process and the consistency of the cleaning effect. The clamping structure enables the vibration generated by the blowing and vibration mechanism and the hammer vibration mechanism during dust removal to be limited only between the two groups of dust removal follower rollers and dust removal clamping rollers, without causing the overall transportation belt to vibrate, thereby avoiding unnecessary influence on other parts of the belt and further protecting the overall structure and operation stability of the belt.

[0016] Preferably, in the above-mentioned automatic cleaning and maintenance device for a mine transportation belt, the blowing and vibration mechanism includes a plurality of air nozzles arranged in a matrix, and the hammer vibration mechanism includes a plurality of elastic vibration hammers arranged in a matrix.

[0017] The blowing and vibration mechanism adopts a plurality of air nozzles arranged in a matrix, and the hammer vibration mechanism adopts a plurality of elastic vibration hammers arranged in a matrix. This arrangement can evenly distribute the blowing and vibration effects on the lower surface of the lower belt body, ensure that each area can be effectively cleaned and vibrated off, improve the uniformity and efficiency of cleaning, and further enhance the cleaning effect. The matrix arrangement of air nozzles and elastic vibration hammers has a relatively simple structure, is convenient for installation and maintenance, reduces the maintenance cost and repair difficulty of the equipment, and improves the reliability and service life of the equipment.

[0018] Preferably, in the above-mentioned automatic cleaning and maintenance device for a mine transportation belt, the plurality of air nozzles and the plurality of elastic vibration hammers are arranged in an alternating manner.

[0019] The plurality of air nozzles and the plurality of elastic vibration hammers are arranged in an alternating manner, so that the stress points on both sides of the lower belt body are different, further enhancing the vibration dust removal effect. This alternating arrangement can generate a more complex vibration mode, making it easier for dust to fall off from the belt surface, further improving the thoroughness of cleaning. The alternating arrangement of air nozzles and elastic vibration hammers can better adapt to pollutants at different positions and distributions on the belt. Whether the pollutants are concentrated or dispersed, they can be effectively cleaned, improving the adaptability of the equipment to different working conditions.

[0020] Preferably, in the above automatic cleaning and maintenance device for a mine transportation belt, a primary dust removal scraper is further provided at the front end of the dust removal part. There is a gap between the blade of the primary dust removal scraper and the lower surface of the lower belt body, so that it can perform primary treatment on the surface dust without contacting the lower surface of the lower belt body.

[0021] A primary dust removal scraper is provided at the front end of the dust removal part. There is a gap between its blade and the lower surface of the lower belt body, and it can perform primary treatment on the surface dust without contacting the lower surface of the lower belt body. This primary treatment can pre-remove some loose dust, reduce the cleaning load of the subsequent air-blowing and hammering mechanisms, and improve the efficiency and effect of the entire cleaning system. The primary dust removal scraper does not directly contact the lower belt body, avoiding possible damage to the belt surface caused by the friction between the scraper and the belt, and further protecting the service life of the belt.

[0022] Preferably, in the above automatic cleaning and maintenance device for a mine transportation belt, the flushing mechanism includes flushing follower rollers and flushing pressing rollers; the number of the flushing follower rollers is two, and the two flushing follower rollers are both arranged below the lower belt body; the number of the flushing pressing rollers is two, and the two flushing pressing rollers are both arranged above the lower belt body and are located between the two flushing follower rollers. When flushing, the flushing follower rollers can press the lower belt body to deform downward under the control of the second telescopic mechanism to form a downwardly convex flushing plane, so that the sprayed water body can be aligned with the flushing plane.

[0023] The flushing mechanism adopts a combination of flushing follower rollers and flushing pressing rollers. Through the control of the second telescopic mechanism, the flushing follower rollers can press the lower belt body to deform downward to form a downwardly convex flushing plane. This design enables the sprayed water body to more accurately align with the flushing plane, improves the flushing effect, ensures that the water body can fully act on the belt surface, and effectively removes pollutants. The cooperation of the flushing follower rollers and the flushing pressing rollers can be dynamically adjusted according to the running state of the belt and the distribution of pollutants, enhancing the adaptability and flexibility of the equipment, and further improving the reliability and stability of flushing.

[0024] Preferably, in the above automatic cleaning and maintenance device for a mine transportation belt, the spraying direction of the sprayed water body is opposite to the running direction of the lower belt body.

[0025] The spraying direction of the water jet is opposite to the running direction of the lower belt body. This design enables the water body to more effectively impact the pollutants on the belt surface, utilizes the running inertia of the belt to enhance the flushing effect, improves the flushing efficiency, and reduces the time and water volume required for flushing. The design of the relative spraying direction can also make the water stains after flushing easier to be dried by the subsequent drying section, reduce the water stain residue on the belt surface, and further optimize the effect of the entire cleaning and maintenance process.

[0026] Preferably, in the above-mentioned automatic cleaning and maintenance device for a mine transport belt, the sweeping and flushing mechanism includes a support frame arranged below the lower belt body, and a plurality of cleaning brushes are installed on the support frame. The cleaning brushes are provided with water spray nozzles. When the sweeping and flushing starts, the support frame can move upward under the control of the third telescopic mechanism, so that the cleaning brushes contact the lower surface of the lower belt body.

[0027] The sweeping and flushing mechanism combines cleaning brushes with water spray nozzles. Through the control of the third telescopic mechanism, the cleaning brushes can contact the lower surface of the lower belt body, realizing deep cleaning. At the same time, the water spray nozzles can moisten the belt during the cleaning process, reduce the friction between the cleaning brushes and the belt, further protect the belt surface, and extend the service life of the belt. The setting of the cleaning brushes can be adjusted according to the type and distribution of pollutants on the belt surface, improving the adaptability and flexibility of cleaning, and being able to better meet the cleaning requirements under different working conditions.

[0028] Preferably, in the above-mentioned automatic cleaning and maintenance device for a mine transport belt, the sweeping and flushing mechanism further includes a support conveyor belt mechanism arranged on the lower belt body. When the sweeping and flushing starts, under the pressing action of the cleaning brushes, the belt of the support conveyor belt mechanism contacts the upper surface of the lower belt body.

[0029] The sweeping and flushing mechanism is increased with a support conveyor belt mechanism. When the cleaning brushes press the lower belt body, the belt of the support conveyor belt mechanism contacts the upper surface of the lower belt body, which can support and limit the belt, prevent the belt from moving during the cleaning process, ensure the stability of the cleaning process and the consistency of the cleaning effect. The outer surface of the belt of the support conveyor belt mechanism is a friction surface, which can better fit with the upper surface of the lower belt body, further enhancing the fixing effect on the belt during cleaning, improving the cleaning effect, and at the same time reducing the damage that may be caused to the cleaning brushes due to the movement of the belt.

[0030] Through the above technical solutions, compared with the prior art, the present invention discloses an automatic cleaning and maintenance device for a mine transport belt, which has the following beneficial effects:

[0031] 1. Comprehensive cleaning and maintenance: Through the organic combination of the dust removal section, water washing section, and drying section, the device realizes the comprehensive cleaning and maintenance of the mine conveyor belt. It not only removes dust and pollutants but also reduces water stain residues through drying, extending the service life of the belt.

[0032] 2. High-efficiency cleaning and low damage: Adopting a dust removal method that combines a blowing and vibrating mechanism with a hammering and vibrating mechanism, and a water washing method that combines a water jet and a brush structure, it can efficiently remove dust and pollutants without damaging the surface of the belt. The cleaning effect is significantly better than traditional methods.

[0033] 3. Structural optimization and stable operation: Both the dust removal section and the water washing section are equipped with protective casings to prevent dust and sewage from overflowing. At the same time, through the design of clamping rollers and follower rollers, the belt is stably operated, avoiding belt deviation or jitter during the cleaning process, ensuring the stability and consistency of the cleaning process.

[0034] 4. Energy conservation, environmental protection, and resource recycling: The circulating pipeline and filtration system of the water washing section can filter and reuse the flushing water, reducing water resource waste, lowering operation costs, and at the same time reducing sewage discharge, meeting environmental protection requirements.

[0035] 5. Strong adaptability and easy maintenance: The design of the device takes into account the complex working environment of the mine. It has a simple structure and is easy to maintain, and can adapt to the cleaning requirements under different working conditions. For example, the design of the primary dust removal scraper, staggered air nozzles and vibrating hammers, adjustable flushing plane, etc. enhances the adaptability of the equipment.

[0036] 6. Reducing maintenance costs and improving production efficiency: By effectively removing pollutants on the belt surface, reducing belt wear and failure rates, the replacement frequency and maintenance costs of the belt are reduced. At the same time, the efficient cleaning process reduces equipment downtime, improving the continuity and economy of mine production.

[0037] 7. Improving the working environment: By reducing dust and sewage overflow, the device can significantly improve the working environment of the mine, reducing the harm to workers' health, meeting the requirements of modern industry for environmental protection and occupational health.

[0069] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0070] See attached Figure 1 to attached Figure 2 As shown in the attached drawings to the attached drawings, the embodiments of the present invention disclose an automatic cleaning and maintenance device for a mine transportation belt, including a mine belt transportation bracket 1 and a transportation belt 2 installed on the mine belt transportation bracket 1; further including: a dust removal section 3, a water washing section 4, and a drying section 5 arranged in sequence in the conveying direction of the lower belt body 21 of the transportation belt 2;

[0071] The dust removal section 3 includes a blowing and vibrating mechanism 31 arranged below the lower belt body 21 and a hammering and vibrating mechanism 32 arranged above the lower belt body 21 and corresponding to and cooperating with the blowing and vibrating mechanism 31. The blowing and vibrating mechanism 31 blows the dust on the lower surface of the lower belt body 21, and makes the lower belt body 21 generate fluctuations by the blowing force of the blowing and vibrating mechanism 31, and cooperates with the hammering and vibrating mechanism 32 to strike and shake off the dust;

[0072] The water washing section 4 includes a flushing mechanism 41 and a sweeping and washing mechanism 42 arranged in sequence in the conveying direction of the lower belt body 21; the flushing mechanism 41 flushes along the direction of the lower surface of the lower belt body 21 by using a jet of water; the sweeping and washing mechanism 42 cleans the lower surface of the lower belt body 21 by combining water flushing and a brush structure;

[0073] The drying section 5 dries the water stains on the lower surface of the lower belt body 21 by blowing air.

[0074] To further optimize the above technical solution, the dust removal section 3 further includes a dust removal protective housing 33. The dust removal protective housing 33 surrounds the outside of the lower belt body 21, and the front and rear side walls respectively have a dust removal housing inlet 332 and a dust removal housing outlet 333 for the lower belt body 21 to pass through. The blowing and vibrating mechanism 31 and the hammering and vibrating mechanism 32 are both installed inside the dust removal protective housing 33; the water washing section 4 further includes a water washing protective housing 43. The water washing protective housing 43 surrounds the outside of the lower belt body 21, and the front and rear side walls respectively have a water washing housing inlet 431 and a water washing housing outlet 432 for the lower belt body 21 to pass through. The flushing mechanism 41 and the sweeping and washing mechanism 42 are both installed inside the water washing protective housing 43.

[0075] In this embodiment, the bottoms of the dust removal protective housing 33 and the water washing protective housing 43 are both funnel-shaped structures. The bottom of the dust removal protective housing 33 is connected to an induced draft fan 38 for collecting the blown and vibrated dust; the bottom of the water washing protective housing 43 is filtered through a circulation pipeline 44 and a filtration system 45 and reused.

[0076] To further optimize the above technical solution, the dust removal section 3 further includes a dust removal follower roller 34 and a dust removal clamping roller 35; the number of the dust removal follower rollers 34 is two, and the two dust removal follower rollers 34 are both arranged above the lower belt body 21 and on the front and rear sides of the hammering and vibrating mechanism 32; the number of the dust removal clamping rollers 35 is two, and the two dust removal clamping rollers 35 are both arranged below the lower belt body 21 and correspond to the two dust removal follower rollers 34 respectively. When the blowing and vibrating mechanism 31 is started, the dust removal clamping roller 35 can cooperate with the corresponding dust removal follower roller 34 to clamp the lower belt body 21 under the control of the first telescopic mechanism 36.

[0077] The clamping structure of the dust removal follower roller 34 and the dust removal clamping roller 35 is set to clamp the lower belt body 21 during dust removal, so that the vibration generated by the blowing and vibrating mechanism 31 and the hammering and vibrating mechanism 32 during dust removal is only limited between the two sets of dust removal follower rollers 34 and dust removal clamping rollers 35, and will not cause the vibration of the overall conveyor belt 2.

[0078] In this embodiment, the central axes of the two dust removal follower rollers 34 are connected between the two side walls of the dust removal protective housing 33, and the dust removal follower rollers 34 are rotatably connected to their central axes. Similarly, the structures of other rollers in this embodiment are also like this. The dust removal follower roller 34 can be in contact with the lower belt body 21 or not. When not in contact, the gap should not be too large. A first bracket 331 is fixed inside the dust removal protective housing 33, and the first bracket 331 is located below the lower belt body 21.

[0079] See appendix Figure 7, the first telescopic mechanism 36 includes a first hydraulic cylinder 361, a first U-shaped frame 362, a telescopic rod 363, and a first spring 364; the cylinder block of the first hydraulic cylinder 361 is fixed on the first bracket 331, the middle rod of the first U-shaped frame 362 is fixedly connected to the piston rod of the first hydraulic cylinder 361, the number of telescopic rods 363 is two, the two telescopic rods 363 are respectively telescopically connected to the two side rods of the first U-shaped frame 362, the ends of the two telescopic rods 363 are fixedly connected to the central axis of the dust removal clamping roller 35, the first spring 364 is sleeved on the telescopic rod 363 and abuts between the end of the central axis of the dust removal clamping roller 35 and the end of the side rod of the first U-shaped frame 362.

[0080] To improve the stability of telescopic control, a first sleeve 365 and a first plug rod 366 are symmetrically arranged on both sides of the first hydraulic cylinder 361. The first sleeve 365 is fixed on the first bracket 331, the first plug rod 366 is fixed on the first U-shaped frame 362, and the first plug rod 366 is slidably inserted into the first sleeve 365.

[0081] See Attachment Figure 3 to Attachment Figure 5 , the blowing and vibrating mechanism 31 includes a plurality of air nozzles 311 arranged in a matrix, and the hammering and vibrating mechanism 32 includes a plurality of elastic hammers 321 arranged in a matrix.

[0082] The blowing and vibrating mechanism 31 further includes a rectangular grid support frame 312. The air nozzles 311 are installed at the grid intersection points of the rectangular grid support frame 312, so that the plurality of air nozzles 311 are arranged in a matrix. The air nozzles 311 are supplied with air through air pipes and are controlled by frequency conversion, so that the plurality of air nozzles 311 blow intermittently, stop after each blow, and then blow again.

[0083] See Figures 5 and Attachment Figure 6 , the hammering and vibrating mechanism 32 further includes a mounting seat 322. The mounting seat 322 is fixed on the inner top surface of the dust removal protection housing 33. The elastic hammer 321 is connected to the mounting seat 322. The elastic hammer 321 includes a pipe seat 3211, a sliding body 3212, a second spring 3213, and a hemispherical rubber head 3214; the pipe seat 3211 is fixed on the mounting seat 322, the sliding body 3212 is partially slidably connected inside the pipe seat 3211, the second spring 3213 is located inside the pipe seat 3211 and abuts between the bottom surface of the pipe seat 3211 and the end face of the sliding body 3212, and the hemispherical rubber head 3213 is fixed on the exposed end face of the sliding body 3212.

[0084] When multiple air nozzles 311 blow air once each, the dust on the lower belt 21 is blown off. At the same time, under the action of the blowing force, the lower belt 21 moves upward to contact the hemispherical rubber head 3214. The hemispherical rubber head 3214 pushes the sliding body 3212 and the second spring 3213 to generate an elastic thrust, which reversely pushes the lower belt 21 to vibrate again, strengthening the dust shedding. Through repeated operations, the dust is cleaned by vibration, and at the same time, the transportation belt 2 will not be damaged by friction.

[0085] To further optimize the above technical solution, multiple air nozzles 311 and multiple elastic hammers 321 are arranged alternately. Although the transportation belt 2 has a certain conveying speed, compared with the reaction speed of the lower belt 21 after the air nozzles 311 spray, it is almost negligible. Therefore, arranging multiple air nozzles 311 and multiple elastic hammers 321 alternately can make the stress points on both sides of the lower belt 21 different, and further strengthen the vibration dust removal effect.

[0086] See attached Figure 8 , a primary dust removal scraper 37 is also provided at the front end of the dust removal part 3. There is a gap between the blade edge of the primary dust removal scraper 37 and the lower surface of the lower belt 21, so that it can perform primary treatment on the surface dust without contacting the lower surface of the lower belt 21.

[0087] The primary dust removal scraper 37 is composed of a vertical plate 371, an inclined rod 372 and a blade 373. The vertical plate 371 is connected to the front side wall of the dust removal protection housing 33 by bolts and is located inside the dust removal protection housing 33. The number of inclined rods 372 is multiple and is fixed to the vertical plate 371. The blade 373 is fixed on multiple inclined rods 372.

[0088] In order to ensure that there is a gap between the blade edge of the blade 373 and the lower surface of the lower belt 21, a strip-shaped hole 3711 is opened on the vertical plate 371. The bolt passes through the strip-shaped hole 3711 and is connected to the dust removal protection housing 33, so that the position of the blade 373 can be adjusted.

[0089] See attached Figure 9 , attached Figure 10 and attached Figure 14 , the flushing mechanism 41 includes a flushing follower roller 411 and a flushing pressing roller 412; the number of flushing follower rollers 411 is two, and the two flushing follower rollers 411 are both arranged below the lower belt 21; the number of flushing pressing rollers 412 is two, and the two flushing pressing rollers 412 are both arranged above the lower belt 21 and are located between the two flushing follower rollers 411. When flushing, the flushing follower roller 411 can press the lower belt 21 to deform downward under the control of the second telescopic mechanism 413, forming a downward convex flushing plane 211, so that the sprayed water body can be aligned with the flushing plane 211.

[0090] In this embodiment, the central axes of the two flushing follower rollers 411 are connected between the two side walls of the water washing protection housing 43. The flushing follower rollers 411 can be in contact with the lower belt body 21 or not. When not in contact, the gap should not be too large.

[0091] See the appendix Figure 11 , the second telescopic mechanism 413 includes a second hydraulic cylinder 4131 and a second U-shaped frame 4132; the cylinder body of the second hydraulic cylinder 4131 is fixed on the inner top wall of the water washing protection housing 43, the middle rod of the second U-shaped frame 4132 is fixed to the piston rod of the second hydraulic cylinder 4131, and both ends of the central axis of the flushing pressing roller 412 are connected to the two side vertical rods of the second U-shaped frame 4132. When starting to flush, the second hydraulic cylinder 4131 controls its piston rod to extend, pressing the upper surface of the lower belt body 21 to facilitate the cleaning of the sprayed water body.

[0092] To improve the stability of telescopic control, a second sleeve 4133 and a second insertion rod 4134 are symmetrically arranged on both sides of the second hydraulic cylinder 4131. The second sleeve 4133 is fixed on the inner top wall of the water washing protection housing 43, the second insertion rod 4134 is fixed on the second U-shaped frame 4132, and the second insertion rod 4134 is slidably inserted into the second sleeve 4133.

[0093] The water washing section 4 further includes a second bracket 46 connected to the inner side of the water washing protection housing 43, and the second bracket 46 is located below the lower belt body 21.

[0094] The flushing mechanism 41 further includes a water spraying frame 414 fixed on the second bracket 46, and water spraying nozzles 415 are installed on the water spraying frame 414.

[0095] To further optimize the above technical solution, the spraying direction of the sprayed water body is opposite to the running direction of the lower belt body 21.

[0096] See the appendix Figure 12 and the appendix Figure 15 , the sweeping and washing mechanism 42 includes a support frame 421 arranged below the lower belt body 21, a plurality of cleaning brushes 422 are installed on the support frame 421, and water spraying ports 4221 are provided on the cleaning brushes 422. When starting to sweep and wash, the support frame 421 can move upward under the control of the third telescopic mechanism 423, so that the cleaning brushes 422 are in contact with the lower surface of the lower belt body 21.

[0097] In this embodiment, see the appendix Figure 13, the third telescopic mechanism 423 includes a third hydraulic cylinder 4231, a third sleeve 4232 and a third insertion rod 4233; the cylinder block of the third hydraulic cylinder 4231 is fixed on the second bracket 46, the piston rod of the third hydraulic cylinder 4231 is fixedly connected with the support frame 421, the number of the third sleeves 4232 is multiple and they are arranged around the third hydraulic cylinder 4231, the third sleeves 4232 are fixed on the second bracket 46, the third insertion rod 4233 is fixed on the bottom surface of the support frame 421, and the third insertion rod 4233 is slidably inserted into the third sleeve 4232.

[0098] The rotating shaft of the cleaning brush 422 is rotatably connected with the support frame 421 and is driven by a motor installed in the support frame 421.

[0099] When cleaning is required, the piston rod of the third hydraulic cylinder 4231 extends, driving the support frame 421 upward, so that the cleaning brush 422 contacts the lower surface of the lower belt body 21. To improve the effect, multiple groups of cleaning brushes 422 can be provided, and the water spraying pressure of the water spraying nozzles 4221 is controlled by different water pressures respectively.

[0100] See the appendix Figure 16 , the sweeping and washing mechanism 42 further includes a support conveyor belt mechanism 424 provided on the lower belt body 21. When the sweeping and washing starts, under the pressing action of the cleaning brush 422, the belt 4241 of the support conveyor belt mechanism 424 contacts the upper surface of the lower belt body 21.

[0101] The outer surface of the belt 4241 of the support conveyor belt mechanism 424 is a friction surface, which can better fit with the upper surface of the lower belt body 21 to prevent the lower belt body 21 from moving during cleaning.

[0102] To improve stability, the support conveyor belt mechanism 424 further includes a support plate 4242. The support plate 4242 is provided inside the support conveyor belt mechanism 424 and fits with the lower inner surface of the belt 4241.

[0103] To further improve the stability of the lower belt body 21 during cleaning, see the appendix Figure 13 and the appendix Figure 17 , vertical rods 425 are fixed at the four corners of the top surface of the support frame 421. Rollers 426 are rotatably connected to the vertical rods 425. Correspondingly, roller grooves 42421 are provided on both sides of the support plate 4242. When the support frame 421 moves upward, the rollers 426 will press the lower belt body 21 and the belt 4241 and then embed into the roller grooves 42421, better restricting the lower belt body 21 and preventing it from moving left and right.

[0104] See the appendix Figure 18, the dryer section 5 includes a drying nozzle support 51 and drying nozzles 52. The drying nozzle support 51 is fixed on the mine belt conveyor support 1, and the drying nozzles 52 are installed on the drying nozzle support 51 and blow air obliquely in the conveying direction of the lower belt body 21.

[0105] The working process of the automatic cleaning and maintenance device for the mine conveyor belt provided in this embodiment is as follows:

[0106] 1. The lower belt body 21 enters the dust removal section 3:

[0107] Primary dust removal stage: The lower belt body 21 of the conveyor belt 2 first passes through the primary dust removal scraper 37. There is a certain gap between the blade of the primary dust removal scraper 37 and the lower surface of the lower belt body 21, and the surface dust is preliminarily treated in a non-contact manner to remove some loose dust and reduce the subsequent cleaning load.

[0108] Blowing and hammering dust removal stage: The lower belt body 21 enters the dust removal protective housing 33. The multiple air nozzles 311 of the blowing mechanism 31 are arranged in a matrix, and the dust on the lower surface of the lower belt body 21 is blown by intermittent air blowing. When the blowing mechanism 31 is started, the dust removal clamping roller 35 can cooperate with the corresponding dust removal follower roller 34 to clamp the lower belt body 21 under the control of the first telescopic mechanism 36. At the same time, the blowing force causes the lower belt body 21 to fluctuate and contact the elastic vibration hammer 321 of the hammering mechanism 32. The hemispherical rubber head 3214 of the elastic vibration hammer 321 pushes the sliding body 3212 and the second spring 3213 to generate an elastic thrust, which reversely pushes the lower belt body 21 to vibrate again, further shaking off the dust.

[0109] 2. The lower belt body 21 enters the water washing section 4:

[0110] Rinsing stage: The lower belt body 21 after dust removal enters the water washing protective housing 43. The washing follower roller 411 and the washing pressing roller 412 of the washing mechanism 41 are controlled by the second telescopic mechanism 413 to press the lower belt body 21 to deform downward, forming a downward convex washing plane 211. The spraying nozzles 415 on the spraying water frame 414 spray water along the direction of the lower surface of the lower belt body 21 and aim at the washing plane 211 for rinsing. The spraying direction is opposite to the running direction of the lower belt body 21 to enhance the rinsing effect.

[0111] Sweeping and washing stage: The lower belt body 21 after rinsing enters the sweeping and washing mechanism 42. The multiple cleaning brushes 422 on the support frame 421 move upward under the control of the third telescopic mechanism 423 and contact the lower surface of the lower belt body 21. The water spraying ports 4221 on the cleaning brushes 422 spray water, and the lower surface of the lower belt body 21 is cleaned in combination with the brush structure. At the same time, the belt 4241 of the support conveyor mechanism 424 contacts the upper surface of the lower belt body 21 to prevent the lower belt body 21 from moving during the cleaning process.

[0112] 3. The lower belt body 21 enters the drying section 5:

[0113] Drying stage: The lower belt body 21 after water washing enters the drying section 5. The drying nozzles 52 are installed on the drying nozzle brackets 51 and blow air towards the lower surface of the lower belt body 21 to dry the remaining water stains by hot air or dry air.

[0114] 4. The belt continues to run:

[0115] The lower belt body 21 after dust removal, water washing and drying continues to run along the conveying direction to complete the entire cleaning and maintenance process. Cleaning can be carried out through multiple cycles.
