Coal mining scraper conveyor usually contain viscous materials, such as coal dust, mud, and powdery materials, some of which stick to the working surface of the conveyor belt and cannot be removed during unloading. At this time, the adhesive material will enter the lower idler wheel of the empty part, soil the roller and stick to these accessories. Material enters the roller shell, thereby increasing the radial load and axial load on the bearing seat of the scraper conveyor, causing the bearing to wear quickly, and the roller shell material tears and pulls the surface of the conveyor belt, accelerating the wear of the conveyor belt.
If the adhesive enters the tail of the coal mining scraper conveyor and turns to the roller, it will stick to the surface of the roller. The greater the viscosity, the stronger the adhesion. The result is that the conveyor belt will be lost and increase the wear of the conveyor belt, causing serious consequences. The remaining material on the conveyor belt of the coal mining scraper conveyor also increases the friction on the roller, sometimes causing the belt surface rubber and the roller cover to tear. If the cleaning device is good, the service life of rollers, conveyor belts, etc. can be extended. It can be seen that the cleaner has a non-negligible influence on the coal mining scraper conveyor. In operation, if you want to manually remove the attachment of the tail roller, it is often easy to cause serious personal injury or death.
Therefore, in order to ensure the normal operation of the coal mining scraper conveyor, the attachments on the conveyor belt must be cleaned between the lifting wheels entering the face.
