Description

Technical Field

[0001] This invention relates to the field of conveyor belt cleaning technology, and particularly to an air-suspended sweeper. Background Technology

[0002] A conveyor belt drive consists of a drive roller, a driven roller, and a conveyor belt. A motor drives the drive roller, which in turn drives the conveyor belt to transport goods. Over time, materials or other items may adhere to the conveyor belt. Failure to clean it properly over a long period can damage the conveyor belt or contaminate the transported goods.

[0003] A device for cleaning the working surface of a conveyor belt, as disclosed in patent application CN117566318A, includes a crankshaft-shaped scraper bracket assembly, left and right side mounting adjustment seat assemblies, and three sets of scraper assemblies (left, middle, and right). The left and right side mounting adjustment seat assemblies are respectively installed at both ends of the scraper bracket assembly, and the three sets of scraper assemblies are connected to the middle of the scraper bracket assembly. The left, middle, and right scraper assemblies clean the working surface of the conveyor belt by contacting the PVC / PVG conveyor belt with the mechanical fastener. The elastic modules embedded in the left, middle, and right scraper assemblies provide a flexible connection between the scraper assemblies and the PVC / PVG conveyor belt with the mechanical fastener, as well as an automatic elastic compensation function. The scraper bracket assembly provides a secure connection and impact resistance for the entire cleaner. The left and right side mounting adjustment seat assemblies provide adjustment and compensation functions for the cleaner and a connection to the on-site material silo foundation.

[0004] During the cleaning process of the conveyor belt surface, scrapers are used to remove debris. To avoid damage to the conveyor, springs are often used for connection. However, springs are prone to fatigue during use, resulting in decreased elasticity and affecting the adjustment of the scraper. Furthermore, during daily use, the surface of the conveyor belt will inevitably develop depressions. Existing scrapers often cannot clean these depressions, thus failing to achieve a thorough cleaning of the conveyor belt. Moreover, as the scraper continues to scrape, a large amount of dust often adheres to the surface, causing pollution instead of cleaning the conveyor belt.

[0005] Therefore, it is necessary to provide an air-suspended sweeper to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an air-suspended sweeper to solve the defects of the prior art mentioned in the background section.

[0007] Based on the above ideas, the present invention provides the following technical solution: an air-suspended sweeper, including a conveying device, and further comprising:

[0008] Two support frames are set at one end of the conveying equipment. The two support frames are fixedly connected to both sides of the conveying equipment. The two support frames are fixedly connected to the mounting support base. The two mounting support bases are rotatably connected to a rotating connecting base on opposite sides.

[0013] As a further embodiment of the present invention: the swing assembly further includes a fixed plate fixedly connected to the cleaning frame, a transmission rod passing through the fixed plate and rotatably connected to the fixed plate, a first bevel gear fixedly connected to the bottom of the transmission rod, a second bevel gear meshing with the outer side of the first bevel gear, a rotating rod rotatably connected to one end of the cleaning frame, the rotating rod passing through the fixed plate and rotatably connected to the fixed plate, the second bevel gear fixedly connected to the outer side of the rotating rod, one end of the rotating rod extending into the inside of the push rod, a transmission gear fixedly connected to one end of the rotating rod, and the transmission gear meshing with the internal gear ring inside the push rod.

[0014] As a further embodiment of the present invention: the elastic element includes a swing rod, the mounting plate has a mounting groove on its outer side, the swing rod is disposed in the mounting groove and slidably connected to the mounting groove, a first spring is fixedly connected between the swing rod and the mounting plate, and a cleaning head is fixedly connected to the end of the swing rod away from the mounting plate.

[0015] As a further aspect of the present invention: a first scraper and a second scraper are provided on one side of a plurality of cleaning frames. The side of the first scraper away from the second scraper is rotatably connected to the cleaning frame, and the side of the second scraper away from the first scraper is rotatably connected to the cleaning frame. Two connecting plates are provided between the first scraper and the second scraper. Both connecting plates are rotatably connected to the first scraper and the second scraper. A sliding plate is fixedly connected to the outside of the connecting plates. A mounting base is fixedly connected to the outside of the cleaning frame. The mounting base passes through the sliding plate and is slidably connected to the sliding plate. A second spring is sleeved on the outside of the mounting base. The two ends of the second spring are fixedly connected to the mounting base and the sliding plate, respectively.

[0016] As a further aspect of the present invention: multiple mounting plates are fixedly connected to fixed racks on their outer sides, multiple cleaning frames are provided with through grooves on the side near the first scraper, and multiple striking elements are provided on the outer side of the mounting plates for striking the second scraper, causing the second scraper and the first scraper to shake and remove dust.

[0017] As a further aspect of the present invention: the striking element includes an L-shaped mounting plate fixedly connected to the outside of the mounting plate, a driven gear rotatably connected to one side of the L-shaped mounting plate, the driven gear meshing with a fixed rack, a rotating disk fixedly connected to one side of the driven gear, a pull plate rotatably connected to one side of the rotating disk, a striking rod rotatably connected to one end of the pull plate, the striking rod penetrating the L-shaped mounting plate and slidably connected to the L-shaped mounting plate, a striking head fixedly connected to one end of the striking rod, the striking head passing through a through groove and contacting a second scraper.

[0018] As a further aspect of the present invention: each of the multiple mounting plates is provided with a foldable airbag at both ends, and the two ends of the foldable airbag are fixedly connected to the mounting plate and the inner wall of the cleaning frame, respectively. Each of the rotating rollers is fixedly connected with an air pipe corresponding to one of the multiple cleaning frames. The air pipe is provided with multiple air holes on its outer side. A connecting pipe is fixedly connected between the air pipe and the foldable airbag. A one-way air outlet valve is provided on the outer side of the connecting pipe. An air inlet pipe is provided on the outer side of the foldable airbag. A one-way air inlet valve is installed on the outer side of the air inlet pipe.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The scraper contacts the surface of the conveyor belt to clean it. However, the spring is prone to fatigue and loss of elasticity during long-term use. In harsh environments, the spring is also prone to corrosion or blockage, affecting the cleaning performance. Therefore, in this solution, a nitrogen spring is hinged to the rotating connecting seat, and the scraper is installed on the outside of the rotating connecting seat. The scraper is adjusted by the nitrogen spring. The pressure of the nitrogen spring can be adjusted by setting a pressure sensor on the outside of the scraper, thereby achieving precise control.

[0021] 2. Through the mounting plate set inside the cleaning frame, the first spring in the elastic element inside the mounting plate pushes the swing rod. The cleaning head at one end of the swing rod extends through the mounting plate to the recess. When the mounting plate rotates with the cleaning frame, the cleaning head cleans the recess on the surface of the conveyor belt. When there are difficult-to-clean protrusions on the surface of the conveyor belt, the rotating connecting seat is rotated by the action of the nitrogen spring, and the rotating roller moves away from the conveyor belt as a whole, thereby avoiding damage to the conveyor belt. However, when the mounting plate moves away from the conveyor belt with the cleaning frame, the elastic element can always keep in contact with the recess, so that it is fully cleaned.

[0022] 3. The transmission gear rotates, which in turn drives the fixedly connected rotating rod to rotate. The rotating rod, through the outer second bevel gear, drives the meshing first bevel gear to rotate, which in turn drives the rotating plate on the first bevel gear to rotate. The push shaft at the top of the rotating plate continuously pulls the limiting frame to swing back and forth, causing the limiting frame to drive the push rod to push the mounting plate to swing inside the cleaning frame. The mounting plate swinging assembly works in conjunction with this to improve the stability of the mounting plate during swinging, so that the multiple elastic elements on the mounting plate come into contact with the surface of the conveyor belt, thereby thoroughly cleaning the surface of the conveyor belt.

[0023] 4. Since the first scraper and the second scraper rotate through a connecting plate, and a sliding plate is fixedly connected to the outside of the connecting plate, the sliding plate slides on the outside of the mounting base. When the striking element strikes, the sliding plate slides on the mounting base, causing one end of the first scraper and the second scraper to face upwards, thus causing the first scraper and the second scraper to elastically change. As the first scraper and the second scraper elastically change, the external cleaning material vibrates and separates from the first scraper and the second scraper. When the cleaning frame rotates with the rotating roller, causing the first scraper and the second scraper to face downwards, the cleaning material is quickly separated with the help of the striking element.

[0024] 5. When cleaning the outer sides of the first and second scrapers through the air outlet, a dust blowing process is performed to improve the dust cleaning effect on the surface of the first and second scrapers. The dust cleaning effect is better by alternating, intermittent, and longer blowing through two foldable airbags. One end of the first scraper is close to the surface of the conveyor belt, and one side of the first scraper is in continuous contact with the surface of the conveyor belt along with the cleaning frame, thereby cleaning the surface of the conveyor belt.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 12 As shown, the air-suspended sweeper includes the following embodiments:

[0041] like Figures 1 to 2 As shown, Embodiment 1 includes a conveying device, and further includes:

[0042] Two support frames 1 are set at one end of the conveying equipment. The two support frames 1 are fixedly connected to both sides of the conveying equipment. The two support frames 1 are fixedly connected to the installation support base 2. The two installation support bases 2 are rotatably connected to a rotating connecting seat 201 on opposite sides. A nitrogen spring 202 is hinged between the rotating connecting seat 201 and the support frame 1.

[0043] In practical implementation, two support frames 1 are detachably installed on both sides of the conveyor frame. When the conveyor is in operation for a long time, a large amount of waste will adhere to the surface of the conveyor belt, so it is necessary to clean the surface of the conveyor belt. The existing conveyor belt uses a spring and a scraper to make the scraper contact the surface of the conveyor belt for cleaning. However, the spring is prone to fatigue and loss of elasticity during long-term use. In harsh environments, the spring is also prone to rust or blockage, affecting the cleaning performance. Therefore, in this solution, a nitrogen spring 202 is hinged to the rotating connecting seat 201, and the scraper is installed on the outside of the rotating connecting seat 201. The scraper is adjusted by the nitrogen spring 202. The pressure of the nitrogen spring 202 can be adjusted by setting a pressure sensor on the outside of the scraper, thereby achieving precise control.

[0044] like Figures 2 to 3 As shown in Embodiment 2: two rotating connecting seats 201 are fixedly connected to the outer side of a fixed support plate 3, and a rotating roller 4 is rotatably connected between the two fixed support plates 3. Multiple cleaning frames 5 are fixedly connected to the outer side of the two rotating rollers 4. Each cleaning frame 5 is provided with a mounting plate 6 inside, and multiple elastic elements are provided inside the mounting plate 6 for contacting the surface of the conveyor belt of the conveying equipment.

[0045] In practice, during daily conveying, a large number of depressions will appear on the surface of the conveyor belt. Existing scrapers often cannot contact the depressions. Even after the scraper cleans the waste inside the depressions, it will still affect the subsequent conveying of other items. Therefore, in this solution, multiple elastic elements are used inside the mounting plate 6 to contact the depressions on the surface of the conveyor belt, thereby achieving surface cleaning.

[0046] Figures 9 to 10 As shown, in this embodiment, a drive motor 401 is fixedly connected to the outer side of one of the fixed support plates 3, and the output shaft of the drive motor 401 is fixedly connected to the rotating roller 4. Fixed disks 711 are fixedly connected to the opposite sides of the two fixed support plates 3, and internal gear rings are fixedly connected to the inner side of the fixed disks 711.

[0047] Multiple cleaning frames 5 are equipped with swing components at both ends to push the mounting plate 6 inside the cleaning frame 5 to swing back and forth, so that the elastic element contacts the recessed area on the surface of the conveyor belt.

[0048] The elastic element includes a swing rod 603. A mounting groove 602 is provided on the outer side of the mounting plate 6. The swing rod 603 is disposed in the mounting groove 602 and slidably connected to the mounting groove 602. A first spring 604 is fixedly connected between the swing rod 603 and the mounting plate 6. A cleaning head 605 is fixedly connected to the end of the swing rod 603 away from the mounting plate 6.

[0049] In practice, when the output shaft of the drive motor 401 drives the rotating roller 4 to rotate, the rotating roller 4 drives the fixedly connected cleaning frame 5 to rotate. As a result, the mounting plate 6 fixedly connected to the outside of the cleaning frame 5 continuously contacts the surface of the conveyor belt, thereby scraping off the waste on the surface of the conveyor belt. For waste in the recessed areas, the first spring 604 in the elastic element inside the mounting plate 6 set inside the cleaning frame 5 pushes the swing rod 603. The cleaning head 605 at one end of the swing rod 603 extends through the mounting plate 6 to the recessed area. When the mounting plate 6 rotates with the cleaning frame 5, the cleaning head 605 cleans the recessed areas on the surface of the conveyor belt. When there are difficult-to-clean protrusions on the surface of the conveyor belt, the rotating connecting seat 201 rotates due to the action of the nitrogen spring 202, thereby moving the rotating roller 4 away from the conveyor belt as a whole, thus avoiding damage to the conveyor belt. However, when the mounting plate 6 moves away from the conveyor belt with the cleaning frame 5, the elastic element can always maintain contact with the recessed area, so that it is thoroughly cleaned.

[0050] like Figures 5 to 7 As shown in Embodiment 3: The swing assembly includes a push rod 701 fixedly connected to one end of the mounting plate 6. The push rod 701 passes through the cleaning frame 5 and is slidably connected to the cleaning frame 5. One end of the push rod 701 is fixedly connected to a limit frame 702. A push shaft 704 is slidably connected inside the limit frame 702. A rotating plate 703 is rotatably connected to the push shaft 704. A transmission rod 705 is fixedly connected to the bottom of the rotating plate 703.

[0051] The swing assembly also includes a fixed plate 706 fixedly connected to the cleaning frame 5. A transmission rod 705 passes through the fixed plate 706 and is rotatably connected to the fixed plate 706. A first bevel gear 707 is fixedly connected to the bottom of the transmission rod 705. A second bevel gear 708 is meshed with the outer side of the first bevel gear 707. A rotating rod 709 is rotatably connected to one end of the cleaning frame 5. The rotating rod 709 passes through the fixed plate 706 and is rotatably connected to the fixed plate 706. The second bevel gear 708 is fixedly connected to the outer side of the rotating rod 709. One end of the rotating rod 709 extends into the inside of the push rod 701. A transmission gear 710 is fixedly connected to one end of the rotating rod 709. The transmission gear 710 meshes with the internal gear ring inside the push rod 701.

[0052] In specific implementation, when the elastic element on the mounting plate 6 inside the cleaning frame 5 cleans as the cleaning frame 5 rotates, in order to ensure that the surface of the conveyor belt can be cleaned, this solution uses a swing component to drive the mounting plate 6 inside the cleaning frame 5 to swing left and right, thereby improving the cleaning effect of the elastic element on the surface of the conveyor belt. Elastic cloths can be installed at both ends of the mounting plate 6 and the cleaning frame 5 to seal the gap between the mounting plate 6 and the cleaning frame 5, preventing dust from entering the mounting plate 6. When the rotating roller 4 rotates, the rotating rods 709 connected to both ends of the multiple mounting plates 6 rotate inside the fixed disk 711, and are connected to the internal gear ring inside the fixed disk 711 via the transmission gear 710. Contact causes the transmission gear 710 to rotate, which in turn drives the fixedly connected rotating rod 709 to rotate. The rotating rod 709 drives the meshing first bevel gear 707 to rotate via the outer second bevel gear 708. Consequently, the rotating plate 703 driven by the first bevel gear 707 rotates. The push shaft 704 at the top of the rotating plate 703 continuously pulls the limiting frame 702 to reciprocate, causing the limiting frame 702 to drive the push rod 701 to push the mounting plate 6 to swing inside the cleaning frame 5. The swinging components of the mounting plate 6 cooperate to improve the stability of the mounting plate 6 during swinging, and to make the multiple elastic elements on the mounting plate 6 contact the surface of the conveyor belt, thereby thoroughly cleaning the surface of the conveyor belt.

[0053] like Figure 4 and Figures 7 to 12As shown in Embodiment 4: A first scraper 801 and a second scraper 802 are provided on one side of multiple cleaning frames 5. The side of the first scraper 801 away from the second scraper 802 is rotatably connected to the cleaning frame 5, and the side of the second scraper 802 away from the first scraper 801 is rotatably connected to the cleaning frame 5. Two connecting plates 803 are provided between the first scraper 801 and the second scraper 802. Both connecting plates 803 are rotatably connected to the first scraper 801 and the second scraper 802. A sliding plate 805 is fixedly connected to the outside of the connecting plate 803. A mounting base 804 is fixedly connected to the outside of the cleaning frame 5. The mounting base 804 passes through the sliding plate 805 and is slidably connected to the sliding plate 805. A second spring 806 is sleeved on the outside of the mounting base 804. The two ends of the second spring 806 are fixedly connected to the mounting base 804 and the sliding plate 805, respectively.

[0054] Multiple mounting plates 6 are fixedly connected to fixed racks 601 on their outer sides. Multiple cleaning frames 5 have through grooves on the side near the first scraper 801. Multiple striking parts are provided on the outer side of the mounting plates 6 for striking the second scraper 802, causing the second scraper 802 and the first scraper 801 to shake and remove dust.

[0055] In specific implementation, in this scheme, the rotating roller 4 rotates in the same direction as the conveyor belt. As the cleaning frame 5 and the mounting plate 6 clean the conveyor belt, a large amount of dust and waste will adhere to the upper part of the cleaning frame 5. If a large amount of dust and debris adheres to the upper part of the mounting plate 6, the cleaning effect will inevitably decrease during subsequent cleaning, and may even contaminate the surface of the conveyor belt. Therefore, in this scheme, a first scraper 801 and a second scraper 802 are set on the upper part of the cleaning frame 5. When dust adheres to the first scraper 801 and the second scraper 802 as it is scraped off, when the swinging component in the above scheme drives the mounting plate 6 to move back and forth, a fixed rack 601 is fixedly connected to the outside of the mounting plate 6. The fixed rack 601 drives multiple striking parts, causing the striking parts to push the second scraper 802 upward. Since the first scraper 801 and the second scraper 802 are connected by a rotating connecting plate 803, the connection... A sliding plate 805 is fixedly connected to the outside of the plate 803. The sliding plate 805 slides on the outside of the mounting base 804. When the striking element strikes, the sliding plate 805 slides on the mounting base 804, causing one end of the first scraper 801 and the second scraper 802 to face upwards, thus causing the first scraper 801 and the second scraper 802 to undergo elastic changes. As the first scraper 801 and the second scraper 802 undergo elastic changes, the external cleaning material vibrates and separates from the first scraper 801 and the second scraper 802. When the cleaning frame 5 rotates with the rotating roller 4, causing the first scraper 801 and the second scraper 802 to face downwards, the cleaning material is quickly separated with the help of the striking element. It is worth noting that the first scraper 801 and the second scraper 802 in this solution are made of elastic material, so when the connecting plate 803 rises, the first scraper 801 and the second scraper 802 can deform.

[0056] like Figure 9 and Figure 11 As shown, in this embodiment: the striking component includes an L-mount plate 901 fixedly connected to the outside of the mounting plate 6. A driven gear 902 is rotatably connected to one side of the L-mount plate 901. The driven gear 902 meshes with the fixed rack 601. A rotating disk 903 is fixedly connected to one side of the driven gear 902. A pull plate 905 is rotatably connected to one side of the rotating disk 903. A striking rod 904 is rotatably connected to one end of the pull plate 905. The striking rod 904 passes through the L-mount plate 901 and is slidably connected to the L-mount plate 901. A striking head 906 is fixedly connected to one end of the striking rod 904. The striking head 906 passes through the through groove and contacts the second scraper 802.

[0057] In specific implementation, when the mounting plate 6 moves, it drives the fixed rack 601 to move. The fixed rack 601 drives multiple meshing driven gears 902 to rotate. The rotation of the driven gears 902 drives the rotating disk 903 to rotate. The rotating disk 903 pushes the striking rod 904 to rotate through the pull plate 905. The striking head 906 at one end of the striking rod 904 strikes the second scraper 802, thereby moving the second scraper 802. An elastic cloth can be set between the first scraper 801 and the second scraper 802 to seal the gap.

[0058] like Figures 5 to 12 As shown in Embodiment 5: Each end of a plurality of mounting plates 6 is provided with a foldable airbag 101. The two ends of the foldable airbag 101 are fixedly connected to the inner walls of the mounting plates 6 and the cleaning frames 5, respectively. Each of the rotating rollers 4 is fixedly connected with an air pipe 102 corresponding to one of the multiple cleaning frames 5. Multiple air holes are provided on the outside of the air pipe 102. A connecting pipe 103 is fixedly connected between the air pipe 102 and the foldable airbag 101. A one-way air outlet valve is provided on the outside of the connecting pipe 103. An air inlet pipe is provided on the outside of the foldable airbag 101. A one-way air inlet valve is installed on the outside of the air inlet pipe.

[0059] In practice, when the swinging components at both ends of the mounting plate 6 inside the cleaning frame 5 push it, foldable airbags 101 are fixedly connected between the two ends of the mounting plate 6 and the cleaning frame 5. When the mounting plate 6 moves to the other side, one of the foldable airbags 101 is compressed, causing the gas inside the foldable airbag 101 to rush into the air pipe 102 through the connecting pipe 103. When the mounting plate 6 moves to the other side, it pulls the compressed foldable airbag 101 to expand and inhale. An air outlet is provided on the outside of the air pipe 102. When cleaning the outer sides of the first scraper 801 and the second scraper 802 through the air outlet, dust blowing is performed to improve the dust cleaning effect on the surface of the first scraper 801 and the second scraper 802. The dust cleaning effect is better by alternating, intermittent, and longer blowing through the two foldable airbags 101. One end of the first scraper 801 is close to the surface of the conveyor belt, and one side of the first scraper 801 is in continuous contact with the surface of the conveyor belt along with the cleaning frame 5, thereby cleaning the surface of the conveyor belt.
