Description

Technical Field

[0001] This utility model relates to the field of mining machinery engineering technology, and in particular to a dust-proof conveying mechanism for ore mining. Background Technology

[0002] Ore mining is a complex and systematic process, mainly including key steps such as exploration, mining, ore processing, beneficiation, and smelting. The exploration stage uses geological methods to determine ore reserves and grade; the mining stage uses open-pit or underground methods to separate and transport the ore from the ore body; the ore processing and beneficiation stages use processes such as crushing, screening, and flotation to improve ore grade, preparing it for subsequent smelting. Modern mining technology emphasizes efficiency, safety, and environmental protection, continuously driving equipment optimization and improving resource utilization.

[0003] In the process of ore mining and transportation, belt conveyors are the core equipment. When the return belt returns to the loading end after completing the material transportation, the surface of the conveyor belt has a certain degree of stickiness. In addition, fine dust and debris in the material are very easy to adhere to the underside of the belt surface under the action of loading, transfer and vibration. If it is not cleaned, it will cause secondary pollution to the conveying corridor and equipment, exacerbate the difficulty of dust control, and increase the cleaning and maintenance costs. Utility Model Content

[0004] One objective of this invention is to provide a dust-proof conveying mechanism for ore mining. This invention addresses the problem mentioned in the background where, during ore mining and conveying, the belt conveyor, as the core equipment, experiences a problem when its return belt, after completing material transport, returns to the loading end. Due to the adhesive nature of the conveyor belt surface, fine dust and debris from the material easily adhere to the underside of the belt surface during loading, transfer, and vibration. If this is not cleaned, it will cause secondary pollution to the conveying corridor and equipment, exacerbating the difficulty of dust control and increasing cleaning and maintenance costs.

[0005] A dust-proof conveying mechanism for ore mining according to an embodiment of the present utility model includes:

[0006] The conveying equipment and the unloading assembly installed at the feed end of the conveying equipment, the unloading assembly including a support frame, a hopper fixedly installed at the center of the support frame, and guide plates alternately arranged from top to bottom inside the hopper;

[0007] The cleaning mechanism includes a collection box installed directly below the conveying equipment and a housing fixed inside the collection box. Racks are movably arranged on both sides of the housing via guide components. A synchronous gear is rotatably arranged between the two racks inside the housing. The racks and the synchronous gear are meshed and driven. Heavy-duty scrapers and soft scrapers are respectively fixed on the back of the racks on the left and right sides via extension arms. The heavy-duty scrapers and soft scrapers are connected to the housing via a drive component to achieve reciprocating wiping motion.

[0008] Preferably, the hopper is located directly above the conveying equipment, and the guide plate is made of wear-resistant rubber.

[0009] Preferably, a collection box is movably disposed at the bottom of the collection box.

[0010] Preferably, the top of the box has a conical structure.

[0011] Preferably, the guide assembly includes a guide rail and a first roller that rotates on the top of the rack. Two first rollers are symmetrically arranged and are movably positioned inside the guide rail.

[0012] Preferably, the extension arm is fixedly disposed between the extension arm and the rack, and extends through the interior of the housing.

[0013] Preferably, both the heavy-duty scraper and the soft scraper are attached to the surface of the conveyor belt of the conveying equipment, and the soft scraper is made of polyurethane.

[0014] Preferably, the drive assembly includes a servo motor fixed to the bottom of the housing and a waist-shaped frame fixed to the bottom of the rack on the right side by bolts. A cam is fixedly provided at the output end of the servo motor, and a second roller is rotatably provided at one end of the waist-shaped frame corresponding to the cam. The second roller is located inside the waist-shaped frame and is movable.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model effectively avoids the problem of secondary pollution caused by the spillage of adhering substances on the return belt surface during the return journey through the cleaning mechanism. In use, the servo motor drives the cam to rotate, which drives the second roller to roll in the waist-shaped frame, forcing the right rack to move horizontally back and forth along the guide rail. Since the racks on both sides are meshed with synchronous gears, the left rack moves synchronously in the opposite direction. The heavy scraper and soft scraper are linked by the extension arm to alternately scrape the lower surface of the conveyor belt. The heavy scraper removes the slag, while the soft scraper finely peels off dust and debris. The scraped-off pollutants fall directly into the movable collection box in the collection box, realizing closed recycling, eliminating corridor pollution, and thus reducing cleaning and maintenance costs.

[0017] 2. This utility model effectively avoids the problem of material falling from a height and impacting the conveyor belt, generating a large amount of impact dust and airborne dust, through the designed feeding component. During use, when the ore falls through the hopper, multiple layers of alternately inclined wear-resistant rubber guide plates receive the material step by step. The upper guide plate deflects the falling direction of the ore, reducing the vertical impact speed, while the lower guide plate provides secondary buffering and guides the ore to fall smoothly onto the conveyor belt. Because the guide plates are made of wear-resistant rubber, they have good elasticity and wear resistance, further reducing friction and impact during the material's fall, thus controlling the generation and spread of dust from the source.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figures 1-4 A dust-proof conveying mechanism for ore mining, comprising:

[0026] The conveying equipment 1 and the unloading assembly 2 installed at the feed end of the conveying equipment 1. The unloading assembly 2 includes a support frame 201. A hopper 202 is fixedly installed at the center of the support frame 201. Guide plates 203 are alternately arranged inside the hopper 202 from top to bottom.

[0027] When in use, as the ore falls through the hopper 202, the multi-layered, alternately inclined guide plates 203 receive the material step by step. The upper guide plate 203 deflects the falling direction of the ore to reduce the vertical impact speed, while the lower guide plate 203 provides secondary buffering and guides the ore to fall smoothly onto the conveyor belt, further reducing friction and impact during the falling process.

[0028] The cleaning mechanism 3 includes a collection box 301 installed directly below the conveying equipment 1, and a box body 303 fixed inside the collection box 301. Racks 305 are movably arranged on both sides of the box body 303 through guide components. A synchronous gear 307 is rotatably arranged between the two racks 305 inside the box body 303. The racks 305 and the synchronous gear 307 are meshed and driven. Heavy-duty scrapers 309 and soft scrapers 310 are respectively fixed on the back of the racks 305 on the left and right sides through extension arms 308. The heavy-duty scrapers 309 and soft scrapers 310 are connected to the box body 303 through a drive component to achieve reciprocating wiping motion.

[0029] The drive assembly includes a servo motor 312 fixed to the bottom of the housing 303, and a waist-shaped frame 311 fixed to the bottom of the right rack 305 by bolts. A cam 313 is fixedly provided at the output end of the servo motor 312. A second roller 314 is rotatably provided at one end of the waist-shaped frame 311 corresponding to the cam 313. The second roller 314 is located inside the waist-shaped frame 311 and is movable.

[0030] In use, the servo motor 312 drives the cam 313 to rotate, which in turn drives the second roller 314 to roll within the waist-shaped frame 311. This forces the right rack 305 to reciprocate horizontally along the guide rail 304. Since both the left and right racks 305 are meshed with the synchronous gear 307, the left rack 305 moves synchronously in the opposite direction. Through the extension arm 308, the heavy-duty scraper 309 and the soft scraper 310 alternately scrape the lower surface of the conveyor belt. The heavy-duty scraper 309 removes the slag, while the soft scraper 310 finely peels off dust and debris. The scraped-off pollutants fall directly into the movable collection box 302 inside the collection box 301, achieving closed-loop recycling.

[0031] Example 1: The hopper 202 is located directly above the conveying equipment 1 to ensure accurate material drop position. The guide plate 203 is made of wear-resistant rubber, which has good elasticity and impact resistance, and can effectively buffer the impact force during the material drop process and reduce dust flying. The collection box 302 is movably installed at the bottom of the collection box 301 to facilitate centralized cleaning of scraped dust and debris. The top of the box 303 has a conical structure to help guide the scraped material to fall smoothly into the collection box 302, avoid residue, and improve cleaning efficiency.

[0032] Example 2: The guide assembly includes a guide rail 304 and a first roller 306 rotating on the top of the rack 305. Two first rollers 306 are symmetrically arranged. The first rollers 306 are located inside the guide rail 304 and are movable to realize the smooth linear motion of the rack 305 in the housing 303, thereby effectively reducing motion friction, reducing wear, and extending service life. At the same time, it ensures the accuracy of the meshing transmission between the rack 305 and the synchronous gear 307, and ensures the stable and reliable reciprocating motion of the heavy scraper 309 and the soft scraper 310, significantly improving the cleaning effect.

[0033] Example 3: The extension arm 308 is fixedly installed between the rack 305 and extends through the interior of the housing 303. The heavy-duty scraper 309 and the soft scraper 310 are both attached to the surface of the conveyor belt of the conveying equipment 1. The heavy-duty scraper 309 is used to remove large particles of adhering material. The soft scraper 310 is made of polyurethane, which is flexible and wear-resistant, and is suitable for fine cleaning of residual dust.

[0034] Working principle: During operation, as the ore falls through the hopper 202, multiple layers of alternating inclined guide plates 203 receive the material step by step. The upper guide plate 203 deflects the direction of the ore's fall, reducing the vertical impact speed. The lower guide plate 203 provides secondary buffering and guides the ore to fall smoothly onto the conveyor belt, further reducing friction and impact during the material's descent. Subsequently, the servo motor 312 drives the cam 313 to rotate, causing the second roller 314 to roll within the waist-shaped frame 311. This forces the right rack 305 to reciprocate horizontally along the guide rail 304. Since both the left and right racks 305 mesh with the synchronous gear 307, the left rack... The rack 305 moves synchronously in the opposite direction, and through the extension arm 308, the heavy-duty scraper 309 and the soft scraper 310 alternately scrape the lower surface of the conveyor belt. The heavy-duty scraper 309 removes the slag, while the soft scraper 310 finely peels off dust and debris. The scraped-off pollutants fall directly into the movable collection box 302 inside the collection box 301, realizing closed-loop recycling. During the process, the first roller 306 in the guide assembly moves within the guide rail 304 to ensure the smooth movement of the rack 305, reduce friction and wear, extend service life, and ensure stable and reliable reciprocating motion of the scraper. Therefore, this device realizes full-process dust control from source dust suppression to end-of-line cleaning.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
