Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and more specifically to a belt cleaning device. Background Technology

[0002] Traditional belt cleaning devices install brushes or rubber or alloy scrapers at the bottom of the belt. The brushes or scrapers are arranged perpendicular to the belt and use scraping or rotating squeezing to clean the material adhering to the belt.

[0003] Traditional belt cleaning devices are effective in the early stages of belt installation, but as the cleaning time increases, the friction between the belt and the conveyed material becomes more severe in the middle than in other areas, resulting in dents. Since the brushes or scrapers cannot be adjusted to the dents, they cannot effectively clean the dented areas, leading to poor belt cleaning results. Summary of the Invention

[0046] The present invention will now be further described with reference to the accompanying drawings.

[0047] See Figures 1 to 4 In specific embodiment 1, an adaptive belt cleaning device includes a curved chain 2 with a brush 3 mounted on it and a conveying mechanism that drives the curved chain 2 to rotate. The conveying mechanism includes left and right drive shafts, on which drive sprockets that drive the curved chain 2 to move are mounted. Either of the left and right drive shafts is connected to a drive motor, thereby realizing the movement of the curved chain. The curved chain, sleeved on the drive sprockets, has a degree of partial lifting movement. The left and right drive shafts are a first drive shaft and a second drive shaft, respectively.

[0048] It also includes a contouring mechanism that drives the bent plate chain 2 to lift in an inverted V-shape; the contouring mechanism includes an active lifting mechanism 4, a driven lifting mechanism 8, and a drive mechanism; auxiliary sprockets matching the bent plate chain 2 are rotatably mounted on both the active lifting mechanism 4 and the driven lifting mechanism 8; the active lifting mechanism 4 is rotatably connected to the first transmission shaft, and one end of the driven lifting mechanism 8 is rotatably connected to the second transmission shaft; the other ends of the active lifting mechanism 4 and the driven lifting mechanism 8 are movably connected through a connector 9; the drive mechanism drives the active lifting mechanism 4 to rotate around the first transmission shaft. This invention, through the combination of the active lifting mechanism 4, the driven lifting mechanism 8, and the drive mechanism, achieves the ejection of the brush 3, thereby achieving the cleaning of the concave area in the middle of the belt.

[0049] The curved chain 2 can rotate within the conveyor mechanism. Additionally, a contouring mechanism, driven by the drive mechanism, can lift the middle of the curved chain 2 according to the belt's concavity, forming an arc surface that roughly matches the belt's concavity. In this way, the brush 3, driven by the curved chain 2, can always maintain effective contact with the belt surface, thus ensuring continuous and effective belt cleaning.

[0050] The active lifting mechanism 4 includes at least two active lifting plates arranged side by side; the driven lifting mechanism 8 includes at least two driven lifting plates arranged side by side; each active lifting plate and each driven lifting plate is rotatably connected to the auxiliary sprocket along its length direction via bearings; the number of active lifting plates, driven lifting plates, and curved plate chains 2 are matched. This facilitates lifting and contouring of the curved plate chains 2. At least three auxiliary sprockets are installed on both the active and driven lifting plates. Preferably, five auxiliary sprockets are installed on both the active and driven lifting plates.

[0051] The drive mechanism includes a drive component and a swing arm linkage assembly 6. The swing arm linkage assembly 6 includes a hinged swing rod and a connecting rod, the top of which is hinged to the active lifting mechanism 4. The swing rod is driven by the drive component, facilitating the lifting of the active lifting mechanism 4 via the drive component. The drive component includes an adjusting shaft 7. The end of the adjusting shaft 7 is connected to the power output end of a worm gear reducer, which is connected to a connecting shaft. A swing rod is mounted on the connecting shaft, facilitating the swinging of the swing rod by the drive component. At least two swing rods are mounted on the connecting shaft, facilitating the driving of multiple active top plates. Preferably, two swing rods are mounted on the connecting shaft. The swing rods are driven by the two active top plates of the active lifting mechanism 4. The swing rods swing in the direction of rotation centerline with the back-and-forth direction as the rotation centerline. The rotation centerline of the swing rod is perpendicular to the central axis of the adjusting shaft. The drive component also includes a drive motor, which is coaxially driven by the adjusting shaft, enabling electric drive of the adjusting shaft. Manual drive can also be achieved using the adjusting shaft alone.

[0052] The adjusting shaft and the connecting shaft are connected by a worm gear reducer with a 90° angle and a self-locking function.

[0053] Specifically, the drive mechanism includes a drive motor and a swing arm linkage assembly 6; the swing arm linkage assembly 6 includes a hinged swing rod and a connecting rod, the top of which is hinged to the active lifting mechanism 4; the swing rod is connected to the drive component for transmission. This facilitates the drive component to drive the active lifting mechanism 4 to lift. The drive component includes an adjusting shaft 7; the end of the adjusting shaft 7 is a worm gear, which meshes with a turbine mounted on a connecting shaft, on which the swing rod is mounted.

[0054] The active lifting mechanism 4 and the driven lifting mechanism 8 are movably connected at their other ends via a connector 9. Specifically, one end of the connector can be detachably connected to the driven lifting mechanism 8; the other end of the connector has an oblong hole; a sliding member that slides within the oblong hole is mounted on the active lifting mechanism 4, and a limiting sleeve for limiting the sliding member within the oblong hole is detachably connected to the sliding member. This facilitates the linkage between the active lifting mechanism 4 and the driven lifting mechanism 8. The sliding member is an annular boss, and a bearing for rotatably connecting an auxiliary sprocket is mounted within the annular boss. In other words, the active top plate and the driven top plate are movably connected via the connector. The sliding member is mounted on the active top plate. The connector is sandwiched between the active top plate and the limiting sleeve.

[0055] The conveying mechanism also includes support plates arranged at the front and rear to support the drive shaft; the left and right ends of the support plates have through holes for the drive shaft to pass through; support mechanisms 5 are installed on both the left and right sides of the support plates. The support plates are rotatably connected to the first drive shaft via bearings, and the support plates are rotatably connected to the second drive shaft via bearings. More preferably, the support mechanism 5 includes a mounting frame, a screw, and support feet. The mounting frame includes a vertical plate and a horizontal plate, and the vertical plate is detachably connected to the support plate; two nuts are threaded onto the screw, arranged vertically and vertically, and the nuts are clamped on the horizontal plate; support feet are installed at the bottom of the screw. This facilitates adjustment of the support height. An adjusting shaft is rotatably connected to a mounting frame via bearings. The adjusting shaft is relatively fixed to the mounting frame via a locking mechanism. The adjusting shaft is mounted on a support plate via bearings. The connecting shaft is rotatably mounted on the support plate via bearings.

[0056] The brush 3 includes a plate and brush bristles. The plate is detachably mounted on the curved plate chain 2. The length direction of the plate is perpendicular to the length direction of the curved plate chain 2. The same plate can be detachably mounted on two curved plate chains 2 arranged side by side.

[0057] The bending chain 2 moves perpendicular to the direction of movement of the belt to be cleaned. The drive motor of the conveyor mechanism rotates, causing the bending chain 2 to rotate, and the brush 3 is locked onto the bending chain 2. Depending on the wear condition of the belt, the adjusting shaft 7 is moved, which can operate the swing arm mechanism 6. The swing arm mechanism 6 pushes the lifting mechanism 4 and the driven lifting mechanism 8. The sprockets on the lifting mechanism 4 and the driven lifting mechanism 8 lift the bending chain 2, causing the bending chain 2 to move in a curved motion. The brush 3 fixed on the bending chain 2 also moves in a curved motion, so that the brush 3 always keeps in contact with the surface of the belt, thereby realizing the curved cleaning of the belt surface formed by wear.

[0058] Beneficial effects: simple structure, easy to manufacture, and low price; its significant advantage is that it can always adjust the cleaning position of the brush 3 according to the condition of the belt dent, which can effectively clean the belt surface.

[0059] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
