Description
Technical Field
[0001] This utility model relates to the field of belt sweeper technology, and in particular to a belt sweeper elastic adaptive adjustment device. Background Technology
[0002] In the industrial transportation of alumina powder, belt conveyor is a common method. Belt cleaners are mainly used to clean up residual materials on the belt, preventing residual materials from spilling and polluting the environment on the return section of the conveyor, and avoiding residual materials sticking to the idlers and causing the return belt to run off-track. At the same time, cleaning the belt can also reduce belt wear. The cleaner plays a vital role in the stable operation of the belt.
[0003] When belt sweepers are in use, existing belt sweeping devices mostly adopt a fixed rigid structure, where the sweeping scraper is directly fixed to the frame with bolts. The contact pressure is determined by the initial installation position. This design can achieve basic sweeping function under normal temperature and constant tension conditions, but it has significant technical defects. First, when the conveyor belt expands and contracts due to temperature changes, the rigid sweeper cannot adapt to the belt deformation, resulting in local overpressure wear or incomplete sweeping. Second, the alumina powder stripped off during the sweeping process is repeatedly squeezed between the scraper and the belt, which easily forms secondary dust and pollutes the working environment. Third, the fixed structure lacks a pressure regulation mechanism. After long-term operation, scraper wear leads to a decrease in contact pressure, requiring frequent shutdowns for adjustment, resulting in high maintenance costs.
[0004] Therefore, to address the aforementioned issues of reducing scraper wear and preventing dust dispersion, a flexible adaptive adjustment device for the belt sweeper can be designed. When the belt sweeper is in use, a closed-loop pressure adjustment mechanism is formed by a pressure spring and an adjusting nut. Through the vertical sliding pair between the guide rod and the fixed rod, the support frame can automatically adjust its displacement according to changes in conveyor belt tension, ensuring that the guide wheel and the sweeping pad maintain a constant contact pressure. This effectively solves the belt wear problem caused by rigid contact. A 45° inclined groove is set at the upper end of the sweeping pad to form a directional flow channel for the peeled alumina. The powder slides down the groove to the dust collection hood area, where it is efficiently collected with the built-in negative pressure device, suppressing secondary dust at the source. The guide wheel serves as the first contact surface for belt alignment, while the cleaning belt is only responsible for scraping off the material. The two are in low-friction contact through polymer materials, which reduces the wear of the cleaning module and improves the system reliability through functional separation. This device integrates mechanical transmission, elastic compensation, and pneumatic collection systems, which significantly improves the cleaning efficiency of the alumina conveying system and the service life of the conveyor belt, thereby reducing scraper wear and avoiding dust flying problems. Utility Model Content
[0005] To overcome the problems of secondary dust generation caused by repeated compression of alumina powder stripped from the scraper between the scraper and the belt during the cleaning process of belt sweepers, and the lack of pressure regulation mechanism in fixed structures, which leads to wear of the scraper and reduced contact pressure after long-term operation, requiring frequent shutdowns for adjustment, thus making it difficult to reduce scraper wear and prevent dust from flying.
[0006] The technical solution of this utility model is as follows: a belt sweeper elastic adaptive adjustment device, including a conveyor frame, a conveyor belt, fixed rods, guide holes, connecting rods, a support frame, guide rods, external threaded grooves, adjusting nuts, pressure springs, guide wheels, sweeping pads, inclined grooves, dust collection hoods, and a dust collection assembly. A conveyor belt is installed above the conveyor frame. Two sets of fixed rods are fixedly installed on the side wall of the conveyor frame. One end of each fixed rod has a through guide hole. A connecting rod is installed below the fixed rod. A support frame is fixedly installed above the connecting rod. Two sets of guide rods are fixedly installed above the connecting rod. The upper side wall of each guide rod has an external threaded groove. An adjusting nut is installed on the upper side wall of each guide rod. A pressure spring is installed above one end of each fixed rod. A guide wheel is rotatably installed above the support frame. A sweeping pad is installed above the support frame. Multiple inclined grooves are formed on the upper inner wall of the sweeping pad. A dust collection hood is installed on one side of the sweeping pad. A dust collection assembly is installed inside the support frame.
[0007] Preferably, when the belt cleaner is in use, during installation, two sets of fixed rods are symmetrically fixed to the side wall of the conveyor frame. The connecting rod forms a vertical sliding pair with the guide hole of the fixed rod through the guide rod. In addition, rotating the adjusting nut can change the preload of the pressure spring, so that the support frame generates an elastic displacement adapted to the tension of the conveyor belt. The guide wheel on the upper part of the support frame maintains sliding contact with the bottom of the conveyor belt, forming the first-level support and guiding system. In the cleaning module, inclined grooves are distributed at a 45-degree angle on the inner wall of the upper end of the cleaning tape, forming a powder guiding channel. When the conveyor belt is running, the adhering alumina powder is scraped off by the cleaning tape and slides directionally along the inclined grooves to the area above the dust collection hood. At this time, it drives the dust collection hood to generate negative pressure and collect the powder. In addition, the pressure adjustment system achieves dynamic compensation through elastic elements. When the conveyor belt expands or contracts due to temperature changes, the compression of the pressure spring is automatically adjusted to maintain the tension of the belt. The device maintains constant contact pressure between the guide wheel and the cleaning belt, ensuring optimal contact angle between them and the conveyor belt. This avoids belt wear caused by rigid contact. A closed-loop control system, comprised of a pressure spring and adjusting nut, precisely controls cleaning pressure, adapts to the dynamic deformation of the conveyor belt, and extends its lifespan. The inclined groove structure improves powder removal efficiency, and combined with a negative pressure dust collection system, effectively solves the problem of fine, easily dispersed alumina powder. The guide wheel, as the primary contact surface, guides the conveyor belt and effectively reduces wear. Combined with polymer materials, it achieves a balance between scraping and protection. Through the integration of mechanical transmission, elastic compensation, and pneumatic collection systems, this device significantly improves the cleaning efficiency of the alumina conveying system and extends the conveyor belt's lifespan, thereby reducing scraper wear and preventing dust dispersion.
[0008] Preferably, the guide rod is slidably disposed inside the guide hole, the adjusting nut is threadedly connected to the external thread groove, the upper end of the pressure spring is in contact with the bottom of the adjusting nut, the lower end of the pressure spring is fixedly connected to the top of one end of the fixed rod, the pressure spring is disposed outside the guide rod, the top of the guide wheel is slidably connected to the bottom of the conveyor belt, and the cleaning belt is disposed below the conveyor belt.
[0009] Preferably, a mounting bracket is fixedly installed on the top of the support frame, and a rotating shaft is rotatably installed inside the mounting bracket, with guide wheels fixedly installed on the side wall of the rotating shaft.
[0010] Preferably, a mounting frame is fixedly installed on the top of the support frame, and a mounting groove is opened inside the mounting frame, with the cleaning leather placed inside the mounting groove.
[0011] Preferably, the cleaning leather has a through-hole with multiple sets of fixing holes. Another set of fixing holes is opened through the inside of the mounting frame. The fixing holes are equipped with fixing bolts. A fixing nut is provided on the side wall of one end of the fixing bolt. The inside of the fixing nut is threadedly connected to the side wall of one end of the fixing bolt.
[0012] Preferably, the vacuuming assembly includes a vacuum hose and a vacuum cleaner. The vacuum hose is fixedly installed inside the support frame, and the upper end of the vacuum hose is connected to the bottom of the dust collection hood. The vacuum cleaner is fixedly installed on the inner wall of the support frame, and the top of the vacuum cleaner is connected to the lower end of the vacuum hose.
[0013] Preferably, the vacuuming assembly also includes an independent bracket, a collection chamber, and a connecting hose. An independent bracket is provided on one side of the connecting rod, a collection chamber is provided above the independent bracket, a connecting hose is provided through the top of the collection chamber, and the bottom of the vacuum cleaner is connected through the upper end of the connecting hose.
[0014] The beneficial effects of this utility model are:
[0015] When the belt cleaner is in use, during installation, two sets of fixed rods are symmetrically fixed to the side wall of the conveyor frame. The connecting rod forms a vertical sliding pair with the guide hole of the fixed rod through the guide rod. In addition, rotating the adjusting nut can change the preload of the pressure spring, causing the support frame to produce an elastic displacement adapted to the tension of the conveyor belt. The guide wheel on the upper part of the support frame maintains sliding contact with the bottom of the conveyor belt, forming the first-level support and guiding system. In the cleaning module, inclined grooves are distributed at a 45-degree angle on the inner wall of the upper end of the cleaning tape, forming a powder guiding channel. When the conveyor belt is running, the adhering alumina powder is scraped off by the cleaning tape and slides directionally along the inclined grooves to the area above the dust collection hood. At this time, it drives the dust collection hood to generate negative pressure and collect the powder. In addition, the pressure adjustment system achieves dynamic compensation through elastic elements. When the conveyor belt expands or contracts due to temperature changes, the compression of the pressure spring is automatically adjusted to maintain the guide. The constant contact pressure between the guide wheel and the cleaning belt ensures that the guide wheel and cleaning belt always maintain the optimal contact angle with the conveyor belt, avoiding belt wear caused by rigid contact. The device forms a closed-loop control system with pressure springs and adjusting nuts, which can precisely control the cleaning pressure, adapt to the dynamic deformation of the conveyor belt, and extend the belt's service life. The inclined groove structure can improve powder removal efficiency, and together with the negative pressure dust collection system, it can collect dust, effectively solving the problem of fine alumina powder being easily scattered.

Its surface maintains sliding contact with the bottom of the conveyor belt 2, forming a first-level support and guidance system. A mounting frame 17 is fixedly installed on the top of the support frame 6. A mounting groove 18 is opened inside the mounting frame 17. The cleaning leather 12 is set inside the mounting groove 18, and the polymer material cleaning leather 12 is embedded into the mounting groove 18 of the mounting frame 17.
[0024] Please see Figure 1 and Figure 3The cleaning leather cover 12 has multiple sets of through-holes 19, with another set of through-holes 19 extending into the mounting frame 17. A fixing bolt 20 is installed inside each fixing hole 19, and a fixing nut 21 is attached to one end of the fixing bolt 20. The fixing nut 21 is threaded into the fixing bolt 20. The cleaning leather cover 12 is aligned with the fixing holes 19 inside the mounting frame 17. Then, the fixing bolt 20 is inserted into the fixing hole 19, and the fixing nut 21 is threaded into the fixing bolt 20, thus mechanically locking the cleaning leather cover 12. The vacuuming assembly includes a vacuum hose 23 and a vacuum cleaner 22. A vacuum cleaner is fixedly installed inside the support frame 6. The upper end of the suction pipe 23 is connected to the bottom of the dust collection hood 14. The vacuum cleaner 22 is fixedly installed on the inner wall of the support frame 6. The top of the vacuum cleaner 22 is connected to the lower end of the suction pipe 23.

The bottom of the vacuum cleaner 22 is connected to the upper end of the connecting hose 24. The powder is transported through the suction pipe 23 to the collection chamber 26 on the independent bracket 25 for collection.
[0025] When the belt cleaner is in use, the device achieves cleaning of the conveyor belt 2 and dust control through the collaboration of multiple modules. During installation, two sets of fixing rods 3 are symmetrically fixed to the side wall of the conveyor frame 1, and the connecting rod 5 forms a vertical sliding pair with the guide hole 4 of the fixing rod 3 through the guide rod 7.
[0026] In addition, rotating the adjusting nut 9 can change the preload of the pressure spring 10, so that the support frame 6 can generate an elastic displacement that adapts to the tension of the conveyor belt 2. The mounting bracket 15 on the upper part of the support frame 6 is equipped with a guide wheel 11 through the rotating shaft 16. Its surface maintains sliding contact with the bottom of the conveyor belt 2, forming the first-level support and guide system.
[0027] In the cleaning module, the polymer cleaning tape 12 is embedded in the mounting groove 18 of the mounting frame 17, and the cleaning tape 12 is aligned with the fixing hole 19 inside the mounting frame 17. Then, the fixing bolt 20 is inserted into the fixing hole 19, and the fixing nut 21 is threaded onto one end of the fixing bolt 20, thereby achieving mechanical locking of the cleaning tape 12. At the same time, the inclined groove 13 is distributed at a 45-degree angle on the inner wall of the upper end of the cleaning tape 12 to form a powder guiding channel.
[0028] When the conveyor belt 2 is running, the adhering alumina powder is scraped off by the cleaning leather 12 and slides down along the inclined groove 13 to the area above the dust collection hood 14. At this time, the vacuum cleaner 22 starts to generate negative pressure, and the powder is transported through the suction pipe 23 and the connecting hose 24 to the collection chamber 26 on the independent bracket 25 for collection.
[0029] In addition, the pressure regulation system achieves dynamic compensation through elastic elements. When the conveyor belt 2 expands or contracts due to temperature changes, the compression of the pressure spring 10 is automatically adjusted to maintain a constant contact pressure between the guide wheel 11 and the cleaning belt 12 on the conveyor belt 2. This elastic adaptive mechanism ensures that the guide wheel 11 and the cleaning belt 12 always maintain the best contact angle with the conveyor belt 2, avoiding belt wear caused by rigid contact.
[0030] This device forms a closed-loop control system with pressure spring 10 and adjusting nut 9, which can precisely control the cleaning pressure, adapt to the dynamic deformation of conveyor belt 2, and extend the belt's service life. The inclined groove structure 13 can improve powder removal efficiency, and together with the negative pressure dust collection system, it can collect dust, effectively solving the problem of fine alumina powder being easily scattered. The guide wheel 11, as the first contact surface, undertakes the guiding function, which can effectively reduce the wear of the cleaning tape 12.

The connecting rod 5 forms a vertical sliding pair with the guide hole 4 of the fixing rod 3 through the guide rod 7. In addition, rotating the adjusting nut 9 can change the preload of the pressure spring 10, so that the support frame 6 produces an elastic displacement that adapts to the tension of the conveyor belt 2. The guide wheel 11 on the upper part of the support frame 6 maintains sliding contact with the bottom of the conveyor belt 2, forming the first-level support and guiding system. In the cleaning module, the inclined grooves 13 are distributed at a 45-degree angle on the inner wall of the upper end of the cleaning tape 12, forming a powder guiding channel. When the conveyor belt 2 is running, the adhering alumina powder is scraped off by the cleaning tape 12 and slides down the inclined grooves 13 to the area above the dust collection hood 14. At this time, the dust collection hood 14 is driven to generate negative pressure and collect the powder. In addition, the pressure adjustment system achieves dynamic compensation through elastic elements. When the conveyor belt 2 expands and contracts due to temperature changes, the compression of the pressure spring 10... The device automatically adjusts the pressure to maintain a constant contact pressure between the guide wheel 11 and the cleaning tape 12 on the conveyor belt 2. This elastic adaptive mechanism ensures that the guide wheel 11 and the cleaning tape 12 always maintain the optimal contact angle with the conveyor belt 2, avoiding belt wear caused by rigid contact. The device forms a closed-loop control system through the pressure spring 10 and the adjusting nut 9, which can accurately control the cleaning pressure, adapt to the dynamic deformation of the conveyor belt 2, and extend the belt's service life.
