Description

Technical Field

[0001] This utility model relates to the technical field of conveyor cleaning equipment, and more specifically to an automatic cleaning device for air cushion conveyors. Background Technology

[0002] Air cushion conveyors utilize devices such as discs, air chambers, and fans to form an air film between the conveyor belt and the discs. An electric motor drives the conveyor belt to transport materials. Air cushion conveyors are characterized by large conveying capacity, long conveying distance, and low energy consumption, and are now widely used in industries such as power, coal, and grain.

[0003] When an air cushion conveyor is running, high-pressure gas is introduced into the air chamber grooves. The high-pressure gas exits from the air holes in the grooves, suspending the conveyor belt. This reduces the friction coefficient of the equipment, improves operating efficiency, and extends the service life of the conveyor belt. Therefore, after material conveying, the bottom of the air cushion conveyor needs to be cleaned to remove dust and other residues left on the grooves during material conveying, preventing dust from clogging the air holes, reducing equipment lifespan, and increasing energy consumption. However, traditional cleaning methods involve manually lifting the conveyor belt and cleaning it with scrapers, brushes, vacuum cleaners, etc., which is labor-intensive, inefficient, and incomplete. Utility Model Content

[0004] This utility model provides an automatic cleaning device for air cushion conveyors, which aims to solve the shortcomings of existing methods for cleaning the bottom of air cushion conveyors, such as manually raising the conveyor belt and cleaning the bottom with tools, which is labor-intensive and incomplete.

[0005] The present invention adopts the following technical solution:

[0006] An automatic cleaning device for an air cushion conveyor includes a support frame, a drive assembly, a cleaning mechanism, and an air compressor. The support frame is formed by four connecting rods connecting to form a rectangular structure. A vertical connecting rod is fixedly connected downwards at each of the four corners of the support frame. A roller is fixedly installed on each vertical connecting rod, and the roller is driven by the drive assembly. The cleaning mechanism includes a first scraper, an air chamber, and a second scraper. The first and second scrapers are arranged parallel to each other along the direction of roller movement. The air chamber is fixed to the top surface of the second scraper, and multiple air holes are evenly distributed on the side of the air chamber facing the first scraper. The two ends of the first scraper are detachably connected to the two front vertical connecting rods via connecting blocks. The two ends of the air chamber are detachably connected to the two rear vertical connecting rods via connecting blocks. The air compressor is connected to the air chamber via an air compressor hose.

[0007] Furthermore, a drive assembly is symmetrically installed on the connecting rod corresponding to the first scraper. The drive assembly includes a first motor and a transmission gear set. The first motor is connected to the roller through the transmission gear set.

[0008] Furthermore, the first motor is fixedly mounted on the connecting rod, and the transmission gear set includes a driving gear and a driven gear. The driving gear is connected to the output shaft of the motor, and the driven gear is coaxially fixed to the bottom surface of the roller.

[0009] Furthermore, roller tracks for the rollers to travel are respectively opened on the inner walls of both sides of the air cushion conveyor.

[0010] Furthermore, the cleaning mechanism also includes two support rods, each of which is installed along the length of the conveyor belt between the two connecting blocks.

[0011] Furthermore, each vertical connecting rod has a downward-extending insert at its bottom, and a corresponding slot is provided on the connecting block; a pin hole is provided on the side of the insert, and a connecting hole matching the pin hole is provided on the side wall of the slot, and the pin hole and the connecting hole are connected by a pin.

[0012] Furthermore, the first scraper is an arc-shaped rigid scraper, and the second scraper is an arc-shaped flexible scraper, both of which are adapted to the curvature of the air cushion conveyor's trough.

[0013] Furthermore, the drive assembly includes a second motor, the power output end of which is connected to a motor shaft, the motor shaft is fixedly connected to a winding reel, a traction rope is connected to the winding reel, and the other end of the traction rope is fixedly connected to a connecting rod.

[0014] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following advantages:

[0015] 1. This utility model includes a support frame, a drive assembly, a cleaning mechanism, and an air compressor. The top of the support frame consists of several connecting rods, with a vertical connecting rod installed downwards at the connection point of each connecting rod. Each vertical connecting rod is detachably connected to a connecting block. The cleaning mechanism includes a first scraper, a second scraper, and an air chamber communicating with the air compressor. The air chamber has multiple air holes. In use, the drive assembly drives the rollers to roll, thereby moving the support frame along the width of the conveyor belt. The first scraper at the front end first pushes the dust on the tray forward, and then the high-pressure airflow from the air compressor is output from the air holes, simultaneously cooperating with the second scraper at the rear end to continue pushing the remaining dust forward, accelerating the dust cleaning work. After the first scraper removes the dust, the device uses a high-pressure airflow in conjunction with a second scraper for secondary cleaning, which can improve the cleaning speed of the air cushion conveyor, reduce labor intensity, and improve cleaning efficiency. Since the support frame is detachable and highly adaptable, it is convenient to use and easy to maintain. At the same time, timely dust removal can prevent the air holes in the tray from being blocked, extend the service life of the equipment, and reduce energy consumption.

[0016] 2. This utility model uses rollers embedded in the roller tracks on both sides of the air cushion conveyor. The first motor drives the transmission gear set on both sides of the rollers, resulting in a stable motion trajectory and strong anti-deviation capability.

[0017] 3. The first and second scrapers of this utility model have an arc-shaped structure that fits into the surface of the groove, which can avoid cleaning blind spots. The air compressor provides continuous pneumatic power, and with the flexible synergistic effect of the second scraper, the cleaning process is more stable and the cleaning effect is better.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details. Well-known components, methods, and processes will not be described in detail below.

[0023] Example 1

[0024] An automatic cleaning device for an air cushion conveyor, as described in the following description. Figure 1 The system includes a support frame 10, a drive assembly 20, a cleaning mechanism 30, and an air compressor 40. The top of the support frame 10 is formed by four connecting rods 101 connecting to form a rectangular structure. Vertical connecting rods 102 are fixedly installed downwards at the four corners of the support frame 10, and a roller 103 is fixedly installed on each vertical connecting rod 102. Roller tracks 104 are respectively opened on the inner walls of both sides of the air cushion conveyor to allow the rollers 103 to move. The rollers 103 are driven to roll by the drive assembly.

[0025] Reference Figure 2Preferably, there are two sets of drive components 20. The drive components 20 are symmetrically mounted on the front connecting rod 101 in the direction of movement of the roller 103. Each drive component 20 includes a first motor 21 and a transmission gear set 22. The first motor 21 is connected to the roller 103 via the transmission gear set 22. The first motor 21 is fixedly mounted on the connecting rod 101. The transmission gear set 22 includes a driving gear 221 and a driven gear 222. The driving gear 221 is connected to the output shaft 210 of the first motor 21. The driven gear is rotatably mounted on the vertical connecting rod 102 and coaxially fixed to the bottom surface of the roller 103. In use, the first motor 21 drives the driving gear 221 to mesh with the driven gear 222, thereby driving the roller 103 to move. The movement trajectory is stable and has strong anti-deviation capability.

[0026] Continue to refer to Figure 1 The cleaning mechanism 30 includes a first scraper 301 at the front end, a second scraper 302 at the rear end, and an air chamber 303. The two ends of the first scraper 301 are detachably connected to two vertical connecting rods 102 at the front end via connecting blocks 304. The two ends of the air chamber 303 are detachably connected to two vertical connecting rods at the rear end via connecting blocks 304. The first scraper 301 and the second scraper 302 are arranged back and forth along the moving direction of the roller 103. The first scraper 301 is an arc-shaped rigid scraper, and the second scraper 302 is an arc-shaped flexible scraper. Both are adapted to the curvature of the air cushion conveyor's trough, which can avoid cleaning blind spots. The air chamber 303 is fixed to the top surface of the second scraper 302. Multiple air holes 304 are evenly distributed on the side of the air chamber 303 facing the first scraper 301. The air compressor 40 is connected to the air chamber 303 via an air compressor hose. With the continuous pneumatic power provided by the air compressor 40, combined with the flexible synergistic effect of the second scraper 301, the cleaning process is more stable and the cleaning effect is better.

[0027] The cleaning mechanism also includes two support rods 305, each of which is installed along the length of the conveyor belt between two connecting blocks 304, which makes the cleaning device more stable.

[0028] The cleaning mechanism 30 of this device (a rigid first scraper 301 at the front end and a flexible second scraper 302 at the rear end) works in conjunction with high-pressure airflow to form a cleaning system. The rigid first scraper 301 can remove most of the accumulated dust. After scraping and cleaning, a secondary blowing is performed on the bottom of the conveyor belt. With the assistance of high-pressure air, the flexible second scraper 302 handles the remaining fine powder, which can improve the cleaning speed of the air cushion conveyor. The first motor 21 drives the transmission gear set 22 to enable the roller 103 to move autonomously, improving cleaning efficiency, reducing labor intensity, and improving cleaning efficiency. At the same time, timely cleaning of dust can prevent the air holes 303 of the tray from being blocked, extending the service life of the equipment and reducing energy consumption.

[0029] Reference Figure 3Each vertical connecting rod 102 has a downwardly extending insert 105 at its bottom. The side of the insert 105 has a pin hole 106. The connecting block 304 has a corresponding slot 306. The side wall of the slot 306 has a connecting hole 307 that matches the pin hole 106. The pin hole 106 and the connecting hole 307 are connected by a pin 308. Since the support frame 10 is detachable, it has high adaptability, is convenient to use, and is easy to maintain.

[0030] For ease of description, the cleaning device is divided into an upper and lower part based on the connection between the vertical connecting rod 102 and the connecting block 306 (i.e., the insert 105 of the vertical connecting rod and the connecting block 304 are detachably connected). The upper part is placed on the conveyor belt, and the rollers 103 on both sides are embedded in the roller tracks 104 on both sides of the air cushion conveyor. The lower part is placed in the head tray of the air cushion conveyor, and the pin hole 106 and the connecting hole 307 are connected by the pin shaft 308. By starting the first motor 21, the first motor 21 drives the transmission gear set 22 to make the rollers 104 roll, which drives the cleaning device forward. The first scraper 301 at the front pushes the coarser dust on the tray forward, and then the high-pressure airflow from the air compressor 40 is output from the air hole 304, which works in conjunction with the second scraper 302 at the rear to continue to push the remaining dust forward, thus speeding up the dust cleaning work.

[0031] Example 2

[0032] Reference Figure 4 The difference between this embodiment and Embodiment 1 is only that: the drive assembly 20 includes a second motor 23, the power output end of the second motor 23 is connected to a motor shaft 231, the motor shaft 231 is fixedly connected to a winding wheel 232, a traction rope 233 is connected to the winding wheel 232, and the other end of the traction rope 233 is fixedly connected to the connecting rod 101.

[0033] In use, the second motor 23 drives the motor shaft 231 to rotate, which in turn drives the traction rope 233 connected to the winding wheel 232, causing the traction rope 233 to drive the roller 104 in the inner roller track 105 of the air cushion conveyor to roll back and forth. The winding wheel 232 can be rotated counterclockwise first to release the traction rope 233 and move the device to the end of the air cushion conveyor. Then, the winding wheel 232 can be rotated clockwise to retract the traction rope 233 and move the device in that direction. (The way the cleaning mechanism cooperates with the air compressor is the same as in Embodiment 1, and will not be described in detail here.)

[0034] The second motor 23 controls the rotation of the winding wheel 232, and the length of the traction rope 233 can be adjusted in real time. This also reduces the weight of the device, makes it easy to install, and saves costs.

[0035] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
