Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to a passive belt cleaning device. Background Art
[0002] As the main conveying equipment for raw materials and fuels, belt conveyors have the characteristics of simple structure, large conveying capacity, and long conveying distance. They are widely used in coal mines, metallurgy, chemical industry and other enterprises. In addition to other equipment reasons, the service life of the conveyor belt is mainly affected by the composition, moisture content, adhesion of materials, production operation and other factors. During the operation of the belt conveyor, it is inevitable that the materials will stick to the surface of the conveyor belt. Various material particles often adhere to the surface of the belt and are difficult to remove. When the working surface of the conveyor belt with materials on the surface passes through the rollers and drums, the materials adhered to the surface of the belt will stick to the rollers and drums, aggravating the wear of the rollers and drums on the belts, and causing the belts to deviate during operation. Moreover, the continuously falling materials also pollute the working environment of the work site, increase the cleaning labor of employees, and affect the physical and mental health of employees. Therefore, cleaning the materials adhered to the surface of the belt is of great significance to improve the service life of the belt, ensure the normal operation of the belt and reduce the labor intensity of employees.
[0003] The belt conveyor cleaner is an indispensable working part of the belt conveyor during operation. It can clean the materials attached to the belt surface. However, the traditional scraper cleaner is easy to damage the belt, and accessories need to be replaced frequently. The cleaner is easy to loosen and may tip over. The belt cleaning effect is poor and the materials cannot be scraped clean. Utility Model Content
[0004] The utility model aims to solve the technical problems existing in the known technology and provides a passive belt cleaning device, which can clean the materials attached to the surface of the belt without damaging the conveyor belt.

[0007] A driven roller brush is arranged on the lower surface of the return belt; the central axis of the driven roller brush is perpendicular to the transmission direction of the return belt; the outer surface of the driven roller brush is provided with bristles;
[0008] The two ends of the active roller are provided with active roller shafts, and the two ends of the driven roller brush are provided with driven roller brush shafts; the active roller shaft is connected with the driven roller brush shaft through a small belt.
[0009] The advantages and positive effects of the utility model are:
[0010] The utility model belongs to an energy-saving cleaning device, which is easy to install, convenient to adjust, simple and practical, does not consume power, compressed air and other energy media, has elastic contact at the cleaning point, reasonable method, good effect, no wear and tear on the conveyor belt, and no scratches, effectively extending the service life of the belt.

[0014] In order to make the above-mentioned purpose, design control system and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0015] like Figure 1 to Figure 2 As shown, the technical solution of the utility model is:
[0016] A passive belt cleaning device, comprising:
[0017] A driving roller 1 is arranged on the upper surface of the return belt 2; the central axis of the driving roller 1 is perpendicular to the transmission direction of the return belt 2;
[0018] A driven roller brush 3 is arranged on the lower surface of the return belt 2; the central axis of the driven roller brush 3 is perpendicular to the transmission direction of the return belt 2; the outer surface of the driven roller brush 3 is provided with bristles; wherein:
[0019] Active roller shafts 4 are provided at both ends of the active roller 1 , and driven roller brush shafts 6 are provided at both ends of the driven roller brush 3 ; the active roller shaft 4 is connected to the driven roller brush shaft 6 via a small belt 5 .
[0020] The length of the driven roller brush 3 is greater than the width of the return belt 2 .
[0021] This embodiment mainly includes: active roller, return belt, driven roller brush, active roller shaft, small belt, driven roller brush shaft and fixed frame. The belt conveyor cannot completely unload the material when unloading. The active roller and driven roller brush are used to sweep the residual material on the belt with the power brought by the operation of the belt, which can quickly remove the material on the working surface of the belt without any external power source. The belt of the belt conveyor is moved by adjusting the roller 8;
[0022] The belt conveyor is fixed by the bracket 7. When transporting materials between the two adjustment rollers 8, when the conveying surface belt turns to the position directly below, it is the return belt 2 at this time, so that the active roller 1 contacts the non-working surface of the conveyor return belt 2 and generates appropriate pressure. The active roller 1 needs to be close to the upper part of the return belt 2. As the return belt 2 runs, the active roller 1 is rotated by friction. The active roller shaft 4 and the driven roller brush shaft 6 are connected by the small belt 5. When the active roller 1 rotates, the small belt 5 is connected to rotate, and the small belt 5 drives the driven roller brush 3 to rotate. The driven roller brush 3 brushes 360 degrees and directly contacts the bottom of the return belt 2. The cleaning point is in elastic contact. When rotating, the residual materials attached to the bottom of the return belt 2 are removed. When the return belt 2 turns to the top, the working surface continues to transport materials. The materials transported on the working surface of the belt do not interfere with the normal operation of the conveyor during the cleaning process.
[0023] The driven roller brush 3 is located below the return belt 2 and is in direct contact with the belt. The rotating active roller 1 drives the driven roller brush 3 to move in the opposite direction, and the rotating driven roller brush 3 cleans the belt running to the lower part.
[0024] The cleaner is installed on the frame of the belt conveyor and set as a fixed frame. When the belt is transporting materials, when the conveying working surface belt turns to the position directly below, it is the return belt, so that the active roller contacts the non-working surface of the conveyor return belt and generates appropriate pressure. As the belt runs, the active roller rotates with the friction force. When the active roller rotates, it drives the small belt to rotate, and the small belt drives the driven roller brush to rotate. The driven roller brush is located below the return belt. The rotation direction of the driven roller brush is opposite to the movement direction of the return belt. The driven roller brush rotates 360 degrees and directly contacts the bottom of the return belt. The cleaning point contacts elastically, so that the attached materials adhering to the working surface of the return belt are swept down to achieve the cleaning purpose. When the return belt turns to the top of the active roller, the material is continued to be transported. The cleaning process does not interfere with the normal operation of the conveyor. The bristles of the driven roller brush can be made of highly elastic or anti-static wear-resistant nylon wire and other materials, which are easy to replace and have better cleaning effects.
[0025] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
