Description

Technical Field

[0001] This utility model relates to the field of material conveying, and in particular to a self-cleaning scraper for belt conveyors. Background Technology

[0002] In the field of industrial material conveying, belt conveyors have become core equipment in industries such as ore, grain, and chemicals due to their efficient and continuous transmission performance. However, traditional belt conveyors have significant technical shortcomings in terms of cleaning and maintenance: First, the efficiency of cleaning residual materials on the belt surface is low. Existing scrapers are mostly fixed structures, which can only scrape off large pieces of material. They are ineffective at cleaning fine particles and sticky impurities adhering to the belt surface. Residual materials are easily spilled and accumulated during belt operation, polluting the production environment. Second, there is a lack of cleaning methods for the lower surface of the belt. Long-term operation leads to dust and oil contamination on the inner side of the belt, which not only accelerates belt wear but may also cause malfunctions such as belt misalignment and slippage due to uneven belt tension. Waste collection is difficult. Traditional cleaning devices do not integrate a waste recycling system, and the cleaned material is scattered around the equipment, requiring secondary manual cleaning, which increases labor intensity and cleaning costs.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] This utility model provides a technical solution: a self-cleaning scraper for a belt conveyor, such as... Figure 1 , Figure 2 As shown, it includes a chassis 1, a conveyor belt 2 on the chassis 1, a reciprocating cleaning mechanism 3 inside the chassis 1, and a scraper cleaning mechanism 4 at one end of the conveyor belt 2.

[0021] like Figures 3-5 As shown, the reciprocating cleaning mechanism 3 includes a dustproof housing 301, a motor 302 is installed inside the dustproof housing 301, a reducer 303 is connected to the output end of the motor 302, a transmission rod 304 is connected to the output end of the reducer 303, a gear 305 is provided on the transmission rod 304, a transmission main shaft 306 is provided on one side of the gear 305, a gear 307 is provided on the transmission main shaft 306, the gear 305 and the gear 307 mesh with each other, and a reciprocating mechanism 308 is provided at both ends of the transmission main shaft 306, and a roller cleaning brush 309 is movably installed on the reciprocating mechanism 308.

[0022] like Figure 6As shown, the reciprocating mechanism 308 includes a positioning plate 308-1, a rotating disk 308-2 rotatably mounted on the positioning plate 308-1, a transmission main shaft 306 passing through the positioning plate 308-1, one side of the rotating disk 308-2 connected to the transmission main shaft 306, and a positioning pin 308-3 eccentrically fixed on the other side of the rotating disk 308-2. Positioning kits 308-4 are provided on both sides of the rotating disk 308-2, and the positioning kits 308-4 are connected to the positioning plate 308-1. The positioning post 308-3 is fitted with a reciprocating assembly 308-5. The positioning post 308-3 is fitted inside the reciprocating assembly 308-5. Connecting brackets 308-6 are fixedly connected to both sides of the reciprocating assembly 308-5. The connecting brackets 308-6 are slidably set inside the positioning assembly 308-4. The connecting brackets 308-6 pass through the dustproof shell 301 and extend to the bottom of the conveyor belt 2. A pair of connecting brackets 308-6 are movably connected to the roller cleaning brush 309.

[0023] like Figure 3 As shown, the scraper cleaning mechanism 4 includes a scraper plate 401, a connecting roller 402 is provided below the scraper plate 401, a cleaning brush 403 is provided on the connecting roller 402, and a waste bin 404 is provided below the connecting roller 402.

[0024] like Figure 1 , Figure 2 As shown, both sides of the conveyor belt 2 are provided with anti-leakage plates 5. The bottom of the anti-leakage plates 5 is connected to the chassis 1. A control platform 6 is provided on one side of the chassis 1. The control platform 6 is electrically connected to the conveyor belt 2 and to the motor 302.

[0025] In practice, the operator starts the conveyor belt 2 via the control platform 6 to begin operation. Simultaneously, the motor 302 is started via the control platform 6. The power of the motor 302 is reduced by the reducer 303 and then transmitted to the transmission rod 304. The transmission rod 304 drives the gear 1 305 to rotate, and the gear 1 305 drives the transmission main shaft 306 to rotate through meshing with the gear 2 307.

[0026] When the drive spindle 306 rotates, it drives the rotating disks 308-2 at both ends to rotate. The positioning pins 308-3 on the rotating disks 308-2 move in a circular motion with the rotating disks 308-2. The reciprocating components 308-5 on the positioning pins 308-3 move in a reciprocating linear motion under the drive of the positioning pins 308-3 and the restriction of the positioning components 308-4. This causes the connecting frame 308-6 to drive the roller cleaning brush 309 to move in a reciprocating motion under the conveyor belt 2 to clean the lower surface of the conveyor belt 2.

[0027] When the conveyor belt 2 reaches one end, the scraper 401 first scrapes off the material on the surface of the conveyor belt 2, initially cleaning the surface. Next, the cleaning brush 403 on the connecting roller 402 further cleans the surface of the conveyor belt 2, brushing off any remaining fine material. The cleaned waste falls into the waste bin 404, achieving waste collection.

[0028] Once the material conveying task is completed, the operator first stops the motor 302 via the control platform 6, thus stopping the reciprocating cleaning mechanism 3. Then, the conveyor belt 2 is stopped, completing the entire workflow.

[0029] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
