Description

Technical Field

[0001] This invention relates to the technical field of conveying and scraping materials, and in particular to an automatic reciprocating scraping mechanism for a conveyor and a conveyor. Background Technology

[0002] Belt conveyors are widely used in industries such as mining, building materials, chemicals, and grain processing, primarily for the continuous conveying of powdery, granular, and small lump materials. During actual operation, factors such as material viscosity, humidity, and equipment vibration can cause some materials to easily adhere to the conveyor belt surface or accumulate on the frame and trough, preventing normal unloading. If accumulated or sticky material is not cleaned promptly, it will increase the conveyor's operating resistance, increase energy consumption, and accelerate belt wear, easily leading to misalignment, jamming, and other malfunctions. In severe cases, it can cause belt tearing, equipment shutdown, and reduced conveying efficiency. Furthermore, long-term accumulation of residual material can easily clump together and generate dust, polluting the working environment and posing certain safety hazards.

[0003] Currently, the main methods for cleaning accumulated material on conveyors in the industry are manual cleaning and traditional equipment cleaning, both of which have significant technical shortcomings. Manual cleaning requires the machine to be stopped, and operators have to manually clean the material in a narrow space. This is not only labor-intensive and extremely inefficient, but also prone to safety accidents such as mechanical collisions and material collapses, and cannot meet the needs of modern continuous automated production.

[0004] Existing automated scraping devices are mostly fixed or simple unidirectional cleaning structures, resulting in poor overall performance. Chain-driven scraping mechanisms are susceptible to dust and humidity conditions, and material particles stuck in the chain links can cause tooth skipping and uneven tension. Long-term operation can lead to transmission failure and component damage. Fixed scraper structures cannot flexibly adjust the scraping height according to material accumulation thickness and conveyor belt spacing, making it difficult to control scraper contact accuracy. This often results in belt wear or missed material scraping, leading to incomplete scraping. Furthermore, traditional devices only support unidirectional cleaning, leaving blind spots at conveyor ends and corners, failing to achieve comprehensive material cleaning. Summary of the Invention

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] Reference Figures 1-5 This embodiment provides an automatic reciprocating scraping mechanism for a conveyor, comprising: A support frame 1 is arranged on the top of the conveyor. A first winch 11 and a second winch 12 are respectively installed at both ends of the support frame 1. A wire rope 13 is wound on the first winch 11, and the other end of the wire rope 13 is wound on the second winch 12. The scraping mechanism 2 is horizontally slidably mounted on the support frame 1, and the scraping mechanism 2 is driven to slide by the wire rope 13; The scraping mechanism 2 includes: The translation bracket 21 is fixedly connected to the wire rope 13. Two roller support rods 22 are symmetrically arranged at both ends of the translation bracket 21. Two support rollers 23 are symmetrically rotatably arranged on each roller support rod 22. The support rollers 23 are rolled on the support frame 1. The cylinder bracket 24 is fixedly connected to the translation bracket 21, and two clamping clamps 25 are symmetrically arranged on the cylinder bracket 24; Two lifting cylinders 26 are respectively fixedly inserted into two clamping hoops 25; The lifting frame 27 has two ends hinged to the bottom output ends of two lifting cylinders 26 respectively, and a lifting plate 28 is provided at the bottom end of the lifting frame 27. An adjustment assembly is mounted on the lifting plate 28 and is equipped with a scraper. In this embodiment, after the cleaning operation is started, the two lifting cylinders 26, installed in the cylinder bracket 24 and fixed by the clamping hoist 25, move synchronously, driving the lifting frame 27, the lifting plate 28, and the scraper to descend as a whole. The height of the scraper is adjusted according to the thickness of the accumulated material, so that the scraper is precisely in contact with the surface of the conveyor belt. The first winch 11 and the second winch 12 are controlled to operate in coordination, and the steel wire rope 13 pulls the translation bracket 21 to move horizontally along the support frame 1. The support rollers 23 roll synchronously, driving the scraper to move forward to complete the forward scraping. When the scraping mechanism reaches the end limit position, the two winches reverse, and the steel wire rope 13 pulls the mechanism back in the opposite direction. After a single cleaning is completed, the lifting cylinders 26... Cylinder 26 retracts, lifting the scraper off the conveyor belt, and the mechanism returns to its initial position, completing one round of work. The support frame 1, the first winch 11, the second winch 12, and the wire rope 13 form a traction system, abandoning the chain drive structure, which is not easily jammed by dust and materials, and will not have the problem of skipping teeth, resulting in strong transmission stability. The cylinder bracket 24, the clamping hoist 25, and the lifting cylinder 26 constitute a lifting adjustment unit, which can flexibly adjust the working height of the lifting frame 27, the lifting plate 28, and the scraper to adapt to different material thicknesses and conveyor belt specifications. It can prevent the scraper from excessively pressing down and wearing the conveyor belt, and improve the scraping quality. Timely cleaning of sticky and accumulated materials can reduce the running resistance of the conveyor and reduce energy consumption.

[0019] As a preferred embodiment of the above technical solution, two side wheel support plates 2a are symmetrically arranged on the outer side wall of each roller support rod 22, and a side guide wheel 2b is horizontally rotatably arranged on each side wheel support plate 2a, and the side guide wheel 2b rolls and fits against the outer side wall of the support frame 1. In this embodiment, during the horizontal reciprocating sliding operation of the scraping mechanism 2 along the support frame 1 by the traction of the wire rope 13, the roller support rod 22 moves synchronously with the translation bracket 21; the side wheel support plate 2a set on the outer wall of the roller support rod 22 can form a stable support for the horizontally rotating side guide wheel 2b, so that the side guide wheel 2b always keeps rolling contact with the outer wall of the support frame 1; when the scraping mechanism 2 reciprocates and moves horizontally, or when it has a tendency to deviate laterally or when it is subjected to lateral force due to scraping resistance, the side guide wheel 2b rolls and limits itself against the side wall of the support frame 1, corrects the travel trajectory of the translation bracket 21 in real time, and works with the top support roller 23 to complete the guiding support, ensuring that the scraping mechanism 2 slides smoothly in a straight line along the support frame 1 throughout the entire process.

[0020] Specifically, the top of the support frame 1 is provided with multiple limiting blocks 2c, which are located at the end of the roller support rod 22 in the horizontal sliding direction to limit the travel of the roller support rod 22. In this embodiment, when the wire rope 13 pulls the scraping mechanism 2 to slide horizontally back and forth along the support frame 1, the roller support rod 22 moves synchronously in a straight line with the translation bracket 21; multiple limiting blocks 2c arranged at the end position of the sliding stroke at the top of the support frame 1 can physically block and limit the roller support rod 22 when it slides to the preset limit position, accurately limiting the maximum reciprocating stroke of the scraping mechanism 2 and preventing the scraping mechanism 2 from sliding beyond its stroke; at the same time, in conjunction with the guiding structure of the side guide wheel 2b and the support roller 23, it ensures that the mechanism always reciprocates within the safe operating range, improving the stability of equipment operation.

[0021] More specifically, the adjustment components include: Adjusting and fixing plate 31 is fixedly installed at the bottom end of the lifting plate 28; Rotary disk 32 is rotatably mounted on the bottom of adjusting fixed disk 31; The scraper bracket 33 is fixedly connected to the outer wall of the rotary disk 32. The scraper bracket 33 is provided with two lifting arms, and each lifting arm is equipped with an adjusting cylinder 34. A swing angle plate 35 is provided, and a swing shaft 36 is fixedly inserted on the swing angle plate 35. The swing angle plate 35 is swayed and mounted on the hoisting arm through the swing shaft 36. A hinge shaft 37 is fixedly inserted on the swing angle plate 35. The output end of the adjusting cylinder 34 is hinged to the hinge shaft 37. A scraper is provided on the swing angle plate 35. In this embodiment, the adjustment assembly is installed at the bottom of the lifting plate 28. During operation, the adjusting fixed plate 31 provides a fixed support, and the rotating plate 32 can rotate relative to the adjusting fixed plate 31, driving the scraper bracket 33 and the bottom scraper to rotate and finely adjust the angle to adapt to different material accumulation states. The lifting arm of the scraper bracket 33 provides an installation reference for the adjusting cylinder 34 and the swing angle plate 35. The output end of the adjusting cylinder 34 is hinged to the swing angle plate 35 through the hinge shaft 37. The swing angle plate 35 can swing slightly relative to the lifting arm by relying on the swing shaft 36. By synchronously extending and retracting the adjusting cylinders 34 on both sides, the swing angle plate 35 is driven to drive the scraper to complete the tilt angle fine adjustment. Combined with the circumferential angle adjustment of the rotating plate 32, the scraper can be adjusted at multiple angles to adapt to the scraping operation requirements of different material accumulation thicknesses and material viscosities on the conveyor belt, thereby improving the scraping quality and operational versatility of the whole machine.

[0022] Furthermore, the adjustment components also include: Friction blocks 3a are provided on each swing angle plate 35; Scraper 3b, with two friction slides 3c arranged parallel to each other on the side end face of scraper 3b, the two friction slides 3c being slidably and locked in the corresponding friction block 3a respectively; Translation cylinder 3d is fixedly connected to two swing angle plates 35; Linkage plate 3e is fixedly installed on the side end face of scraper 3b and is fixedly connected to the output end of translation cylinder 3d. In this embodiment, after the adjustment component completes the scraper angle and posture adjustment, when the equipment performs reciprocating scraping operation, the friction block 3a on the swing angle plate 35 and the friction slide bar 3c on the side end face of the scraper 3b slide and engage, providing lateral sliding guidance and support for the scraper 3b; the translation cylinder 3d is fixed on the two swing angle plates 35, and its output end is rigidly connected to the scraper 3b through the linkage plate 3e; during operation, the translation cylinder 3d can extend and retract, driving the linkage plate 3e to drive the scraper 3b to move laterally along the guide direction of the friction block 3a and the friction slide bar 3c, realizing dynamic fine adjustment of the working width of the scraper 3b, completing multi-dimensional adaptive scraping adjustment, adapting to the material distribution conditions at different positions of the conveyor belt, thereby improving the equipment's versatility and scraping accuracy.

[0023] Furthermore, the cross-section of the friction surface inside the friction block 3a is set to a right angle shape. The friction surface of the friction block 3a is fitted and attached to the corner of the friction slide 3c, so that the friction slide 3c and the friction block 3a slide and cooperate. Through the cooperation of the upper and lower opposing friction blocks 3a and the two friction slides 3c, the scraper 3b and the friction slide 3c are indirectly installed on the swing angle plate 35. In this embodiment, during assembly, the friction surface of the right-angled section inside the friction block 3a is precisely engaged with the corner of the friction slide 3c. The upper and lower corresponding friction blocks 3a form a limiting clamp on the two sets of friction slides 3c, firmly assembling the scraper 3b onto the swing angle plate 35. When the translation cylinder 3d drives the scraper 3b to slide laterally to adjust the cleaning width, the right-angled friction surface always maintains a close sliding fit with the friction slide 3c, restricting the vertical and radial movement of the scraper 3b and retaining only the horizontal sliding degree of freedom. This ensures that the scraper 3b slides smoothly along the preset trajectory throughout the entire process, and completes precise scraping operations in conjunction with the multi-dimensional adjustment structure of the whole machine. This clamping structure is easy to assemble and disassemble, facilitating the inspection and replacement of the scraper 3b and reducing equipment maintenance costs.

[0024] Furthermore, a rotary motor 42 is provided on the top of the hoisting plate 28, and a gear 43 is rotatably provided at the bottom output end of the rotary motor 42. A gear ring 41 is rotatably provided inside the adjusting and fixing disk 31. The inner ring of the gear ring 41 is provided with teeth. The gear ring 41 and the gear 43 mesh with each other, and the gear ring 41 is fixedly connected to the rotating disk 32. In this embodiment, the rotary motor 42 installed on the top of the hoisting plate 28 starts running, driving the bottom gear 43 to rotate synchronously; the gear 43 and the gear ring 41 inside the adjusting fixed plate 31 form a meshing transmission, and through the gear meshing power transmission, the gear ring 41 is driven to rotate smoothly inside the adjusting fixed plate 31; since the gear ring 41 is fixedly connected to the rotating plate 32, it can further drive the rotating plate 32 and the overall scraper bracket 33 and scraper 3b below to rotate synchronously in the circumferential direction, realize the automatic and precise adjustment of the overall angle of the scraper, meet the cleaning needs of different material accumulation conditions, and thus improve the equipment's adaptability to working conditions and cleaning versatility.

[0025] Furthermore, the cross-section of scraper 3b is set to be arc-shaped, with the concave surface of scraper 3b facing the direction of material movement; In this embodiment, when the scraping mechanism moves horizontally back and forth along the support frame 1 to carry out the cleaning operation, the arc-shaped scraper 3b moves synchronously with its concave surface facing the scraping direction. The arc-shaped concave surface of the scraper 3b first contacts the accumulated and sticky material on the surface of the conveyor belt. Utilizing the guiding and gathering characteristics of the arc-shaped surface, the dispersed and sticky material is concentrated and gathered towards the center of the scraper. As the mechanism continues to move horizontally, the arc-shaped cutting edge that fits the conveyor belt gradually scrapes off the sticky material as a whole, pushing it away from the surface of the conveyor belt, reducing the situation where the material scatters to both sides of the scraper, and completing the efficient cleaning operation of the entire conveyor belt.

[0026] Furthermore, the main body of the wire rope 13 is parallel to the length direction of the support frame 1; In this embodiment, during equipment operation, the first winch 11 and the second winch 12 wind up and unwind the wire rope 13. Since the main body of the wire rope 13 is arranged parallel to the length direction of the support frame 1, the traction force direction of the wire rope 13 is completely coincident with the preset sliding trajectory of the scraping mechanism 2. The traction power can be evenly output along the straight line of the support frame 1, stably pulling the entire scraping mechanism 2 to make horizontal linear reciprocating motion along the support frame 1. In conjunction with the side guide wheel 2b and the support roller 23, the translational stability of the scraping mechanism 2 is improved.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
